From 573fc0937c11bba4f1590ad1bb97d8b39382c7ac Mon Sep 17 00:00:00 2001 From: Brian Gebel Date: Sat, 14 Mar 2026 19:50:24 -0700 Subject: [PATCH 01/25] feat(plugins): complete CGC plugin extension system (001-cgc-plugin-extension) Implements the full plugin extension system allowing third-party packages to contribute CLI commands and MCP tools to CGC via Python entry points. Core infrastructure: - PluginRegistry: discovers cgc_cli_plugins/cgc_mcp_plugins entry-point groups, validates PLUGIN_METADATA, enforces version constraints, isolates broken plugins - CLI integration: plugin commands attached to Typer app at import time; `cgc plugin list` - MCP server integration: plugin tools merged into tools dict; handlers routed at call time Plugins implemented: - cgc-plugin-stub: minimal reference fixture for testing and authoring examples - cgc-plugin-otel: gRPC OTLP receiver, Neo4j writer (Service/Trace/Span nodes, CORRELATES_TO links to static Method nodes), MCP query tools - cgc-plugin-xdebug: DBGp TCP listener, call-stack parser, dedup writer (StackFrame nodes, CALLED_BY chains, RESOLVES_TO Method links), dev-only - cgc-plugin-memory: MCP knowledge store (Memory/Observation nodes, DESCRIBES edges to Class/Method, FULLTEXT search, undocumented code queries) CI/CD and deployment: - GitHub Actions: plugin-publish.yml (matrix build/smoke-test/push via services.json), test-plugins.yml (PR plugin unit+integration tests) - Docker: docker-compose.plugin-stack.yml (self-contained full stack with Neo4j healthcheck + init.cypher), plugin/dev overlays, all plugin Dockerfiles - Kubernetes: otel-processor and memory plugin Deployment+Service manifests - Fixed docker-compose.template.yml: neo4j healthcheck was missing (broke all overlay depends_on: service_healthy conditions), init.cypher now mounted Tests (74 passing, 17 skipped pending plugin installs): - Unit: PluginRegistry, OTEL span processor, Xdebug DBGp parser - Integration: OTEL neo4j_writer, memory MCP handlers, plugin load isolation - E2E: full plugin lifecycle, broken plugin isolation, MCP server routing Documentation: - docs/plugins/authoring-guide.md: step-by-step plugin authoring with examples - docs/plugins/cross-layer-queries.md: 5 canonical cross-layer Cypher queries (SC-005) - docs/plugins/manual-testing.md: Docker and Python testing paths, per-plugin verification sequences, troubleshooting table - docs/plugins/examples/send_test_span.py: synthetic OTLP span sender for OTEL testing - .env.example: documented all plugin environment variables - CLAUDE.md: updated with plugin directories, entry-point groups, test commands Co-Authored-By: Claude Sonnet 4.6 --- .env.example | 22 +

Key Design Decisions + +**Why Python for otel-processor and xdebug-listener?** +The `opentelemetry-sdk` Python package has excellent OTLP receiver support and Neo4j's official `neo4j` Python driver is the most mature. Keeps both services consistent. + +**Why same Neo4j database (not separate databases)?** +Cross-layer queries require traversing between node types. If CGC static nodes and OTEL span nodes are in different databases, you cannot do `MATCH (s:Span)-[:CORRELATES_TO]->(m:Method)` in a single query. The unified schema with `source` property labels is sufficient to distinguish origins. + +**Why the OTel Collector in between?** +Direct OTLP from app → otel-processor works but is fragile. The collector handles batching, retry on failure, and gives you a place to add sampling rules or additional exporters (e.g., Jaeger for visual trace inspection) without touching application config. + +**Why `mcp/neo4j-memory` rather than a custom memory service?** +It's maintained, well-documented, and covers the generic memory use case well. The value of CGC-X is the unified graph — not reinventing memory storage. + +**Xdebug `trigger` mode rather than `yes` mode?** +`yes` mode captures every request, generating massive graph noise and degrading performance. `trigger` mode lets you selectively capture specific requests using the `XDEBUG_TRIGGER` cookie/header, giving you targeted, high-quality traces. diff --git a/config/neo4j/init.cypher b/config/neo4j/init.cypher new file mode 100644 index 00000000..4014d75b --- /dev/null +++ b/config/neo4j/init.cypher @@ -0,0 +1,38 @@ +// CGC Plugin Extension — Graph Schema Initialization +// Run this against Neo4j after startup to create all constraints and indexes. +// Idempotent: uses IF NOT EXISTS throughout. + +// ── OTEL Plugin: Service nodes ───────────────────────────────────────────── +CREATE CONSTRAINT service_name IF NOT EXISTS + FOR (s:Service) REQUIRE s.name IS UNIQUE; + +// ── OTEL Plugin: Trace nodes ─────────────────────────────────────────────── +CREATE CONSTRAINT trace_id IF NOT EXISTS + FOR (t:Trace) REQUIRE t.trace_id IS UNIQUE; + +// ── OTEL Plugin: Span nodes ──────────────────────────────────────────────── +CREATE CONSTRAINT span_id IF NOT EXISTS + FOR (s:Span) REQUIRE s.span_id IS UNIQUE; + +CREATE INDEX span_trace IF NOT EXISTS + FOR (s:Span) ON (s.trace_id); + +CREATE INDEX span_class IF NOT EXISTS + FOR (s:Span) ON (s.class_name); + +CREATE INDEX span_route IF NOT EXISTS + FOR (s:Span) ON (s.http_route); + +// ── Xdebug Plugin: StackFrame nodes ─────────────────────────────────────── +CREATE CONSTRAINT frame_id IF NOT EXISTS + FOR (sf:StackFrame) REQUIRE sf.frame_id IS UNIQUE; + +CREATE INDEX frame_fqn IF NOT EXISTS + FOR (sf:StackFrame) ON (sf.fqn); + +// ── Memory Plugin: Memory + Observation nodes ────────────────────────────── +CREATE FULLTEXT INDEX memory_search IF NOT EXISTS + FOR (m:Memory) ON EACH [m.name, m.entity_type]; + +CREATE FULLTEXT INDEX observation_search IF NOT EXISTS + FOR (o:Observation) ON EACH [o.content]; diff --git a/config/otel-collector/config.yaml b/config/otel-collector/config.yaml new file mode 100644 index 00000000..52dcdab2 --- /dev/null +++ b/config/otel-collector/config.yaml @@ -0,0 +1,33 @@ +receivers: + otlp: + protocols: + grpc: + endpoint: 0.0.0.0:4317 + http: + endpoint: 0.0.0.0:4318 + +processors: + batch: + timeout: 5s + send_batch_size: 512 + + filter/drop_noise: + error_mode: ignore + traces: + span: + -

Justified because: (a) the feature requires extensibility without forking core — a non-negotiable requirement; (b) `importlib.metadata` entry-points is Python stdlib — minimal abstraction; (c) without a registry, adding each plugin would require modifying `server.py` and `cli/main.py` permanently, producing a worse monolith.

Three current plugins + third-party extensibility require a clean registration boundary. | Hardcoding plugins in `server.py`/`main.py` defeats the extensibility requirement entirely. There is no simpler path to the stated goal. | +| gRPC server in OTEL plugin | OTLP protocol uses gRPC. The Python opentelemetry-sdk is tracer-side only and cannot act as a receiver. | Pure HTTP OTLP would require the same gRPC-level effort and provides less tooling ecosystem support. The OTel Collector (sidecar) already handles the edge; gRPC is the right interface for collector → processor. | +| Multiple new graph node types | Runtime and memory layers produce genuinely different data (spans, frames, knowledge entities). Reusing existing `Method`/`Class` nodes for runtime data would corrupt the static layer. | Cannot collapse runtime nodes into static nodes — they represent different semantic things (observed execution vs. declared code). The `source` property differentiates them without schema explosion. | diff --git a/specs/001-cgc-plugin-extension/quickstart.md b/specs/001-cgc-plugin-extension/quickstart.md new file mode 100644 index 00000000..ab880bdc --- /dev/null +++ b/specs/001-cgc-plugin-extension/quickstart.md @@ -0,0 +1,211 @@ +# Quickstart: CGC Plugin Extension System + +**Feature**: 001-cgc-plugin-extension +**Audience**: Developers setting up CGC-X locally and contributors building plugins + +--- + +## Prerequisites + +- Python 3.10+ +- pip / virtualenv +- Docker + Docker Compose (for container services) +- A running Neo4j instance (or use the provided docker-compose) + +--- + +## 1.

CGC calls +`app.add_typer(plugin_app, name=cmd_name)` for each loaded plugin. + +**Rationale**: Typer's `add_typer()` is the idiomatic way to compose command groups. The +pattern requires the plugin to own its Typer app (clean separation), and CGC to own the +top-level `app` (clean host). Returning a tuple rather than a dict is simpler for the +common case (one command group per plugin) and is consistently typed. + +**Startup sequence**: +``` +CLI main.py imports → PluginRegistry discovers cgc_cli_plugins entries → +calls each get_plugin_commands() → app.add_typer() for each → Typer starts +``` + +**Alternatives considered**: +- Plugin directly calls `app.add_typer()` — creates bidirectional coupling; plugin + imports core at registration time which can cause circular imports +- Plugin returns a Click group — Typer wraps Click but mixing levels is error-prone; + Typer's add_typer is cleaner + +--- + +## R-003: MCP Plugin Interface + +**Decision**: Each MCP plugin entry point resolves to a function +`get_mcp_tools(server_context: dict) -> dict[str, ToolDefinition]` that returns a +mapping of tool name → tool definition dict (same schema as core `tool_definitions.py`). +CGC's `MCPServer._load_plugin_tools()` merges these into its tools manifest and routes +calls via a unified `handle_tool_call()` dispatcher. + +**Server context passed to plugins** (minimal, read-only intent): +```python +{ + "db_manager": self.db_manager, # shared database connection + "version": "x.y.z", # CGC core version string +} +``` + +**Rationale**: Plugins receive the `db_manager` so they can share the existing database +connection rather than opening independent connections (violating the constitution's +single-database principle). Passing only what is needed (not `self`) prevents plugins +from calling internal server methods they shouldn't access. + +**Tool handler registration**: The plugin's `get_mcp_tools()` return value maps +tool names to JSON Schema definitions. The plugin ALSO registers handler callables +in a separate `get_mcp_handlers()` function (or combined in a single object). The +server stores handlers in `self.plugin_tool_handlers` dict and routes calls there +before checking built-in handlers. + +**Alternatives considered**: +- Subclass MCPServer per plugin — couples plugin to server implementation; not viable + for third-party plugins +- Plugin monkey-patches server — completely unsafe and untestable +- gRPC plugin protocol — overkill for in-process plugins; entry-points are sufficient + +--- + +## R-004: Plugin Version Compatibility + +**Decision**: Each plugin's `__init__.py` declares `PLUGIN_METADATA` dict with a +`cgc_version_constraint` key using PEP-440 version specifier syntax (e.g. +`">=0.3.0,<1.0"`). CGC's `PluginRegistry` validates this against the installed +`codegraphcontext` package version using `packaging.specifiers.SpecifierSet`. + +**On mismatch**: plugin is skipped with a WARNING log; all compatible plugins still load; +no error is raised to the user unless zero plugins load. + +**Rationale**: `packaging` is already an indirect dependency of pip and is present in +all virtual environments. PEP-440 specifiers are the Python standard for version +constraints. Soft-fail (warn, skip) rather than hard-fail ensures partial plugin +ecosystems remain usable. + +**Alternatives considered**: +- Semver-only checking — PEP-440 is a superset and already the ecosystem standard +- No version checking — risks silent breakage when core APIs change + +--- + +## R-005: Plugin Isolation (Error Containment) + +**Decision**: Wrap each plugin load in a `try/except Exception` block. Use a +`PluginRegistry` class that catches `ImportError`, `AttributeError`, `TimeoutError`, and +generic `Exception` at each stage (import, metadata read, command/tool registration). +A broken plugin logs an error and sets `failed_plugins[name] = reason`; it NEVER +propagates an exception to the host process. + +**Timeout**: On Unix, `signal.SIGALRM` with a 5-second timeout prevents hanging imports. +(Windows lacks SIGALRM — on Windows, timeout is skipped with a warning.) + +**Startup summary**: After all plugins are processed, CGC logs: +``` +CGC started with 19 built-in tools and 6 plugin tools (1 plugin failed). + ✓ cgc-plugin-otel 4 tools + ✓ cgc-plugin-memory 2 tools + ✗ cgc-plugin-xdebug SKIPPED: missing dependency 'dbgp' +``` + +**Rationale**: The spec requires (FR-003) that plugin failures do not prevent CGC core +from starting. Isolation at the `PluginRegistry` boundary is the cleanest enforcement. + +--- + +## R-006: OTEL Span Receiver Architecture + +**Decision**: Deploy the standard OpenTelemetry Collector (`otel/opentelemetry-collector-contrib`) +as a sidecar. It receives OTLP from applications and forwards to the OTEL plugin service +via OTLP gRPC. The plugin service implements a Python gRPC server using `grpcio` + +`opentelemetry-proto` protobuf definitions. + +**Rationale**: The Python `opentelemetry-sdk` is tracer-side only — it cannot act as an +OTLP gRPC receiver endpoint. Using the official OTel Collector as a sidecar provides +batching, retry, filtering, and sampling for free before spans reach the custom processor. +This is the established production pattern (used by Datadog, Honeycomb, Jaeger agents). + +**Key packages**: +- `grpcio>=1.57.0` — gRPC server implementation +- `opentelemetry-proto>=0.43b0` — generated protobuf/gRPC classes +- `neo4j>=5.15.0` — async Python driver + +**Write pattern**: Async batch writer using `asyncio.Queue` with configurable +`max_batch_size=100` and `max_wait_ms=5000`. MERGE on `(trace_id, span_id)` for +idempotency. Dead-letter queue for resilience when Neo4j is temporarily unavailable. + +**Alternatives considered**: +- Pure Python OTLP HTTP receiver (no gRPC) — simpler but less efficient; OTel Collector + already handles the gRPC ↔ HTTP translation if needed +- Direct OTLP from app → Python service — fragile; the Collector adds resilience + +--- + +## R-007: Xdebug DBGp Listener + +**Decision**: Implement a minimal TCP server using Python's stdlib `socket` and +`xml.etree.ElementTree` modules. No external DBGp library is required — the protocol +is XML over TCP and is simple enough to implement directly. + +**Protocol flow**: PHP Xdebug connects → init packet received → `run` command sent → +on each breakpoint, send `stack_get` → parse XML response → upsert `StackFrame` nodes +and `CALLED_BY` edges → send `run` → repeat until connection closes. + +**Deduplication**: Hash the call chain (`sha256(class::method|...) [:16]`) with an +LRU cache (size configurable, default 10,000). If hash seen recently, skip upsert. +This prevents the same execution path from creating duplicate graph structure. + +**Dev-only deployment**: The Xdebug plugin starts its TCP listener only when enabled +(`CGC_PLUGIN_XDEBUG_ENABLED=true`). In production Docker Compose, the `xdebug` service +is absent from the default compose file; it exists only in `docker-compose.dev.yml`. + +**Rationale**: Xdebug is a dev tool. Running a DBGp listener in production is a security +risk. The plugin MUST default to disabled and require explicit opt-in. + +--- + +## R-008: Memory Plugin Architecture + +**Decision**: The memory plugin is a thin wrapper. The underlying storage is provided by +the `mcp/neo4j-memory` Docker image (official, maintained). The plugin package in CGC: +1. Provides a `cgc plugin memory enable/disable/status` CLI command group +2. Proxies MCP tool definitions so they appear in CGC's tool listing even though the + actual service runs separately +3. Provides a `docker-compose.yml` snippet and Kubernetes manifests for deployment + +**Rationale**: The research document explicitly states "Why mcp/neo4j-memory rather than +a custom memory service? It's maintained, well-documented, and covers the generic memory +use case well." Building custom memory storage would violate the Simplicity principle +(V) — unnecessary complexity for solved problems. + +**Neo4j sharing**: The memory plugin connects to the same Neo4j instance as CGC core, +enabling cross-layer queries (`(Memory)-[:DESCRIBES]->(Method)`) as specified. + +--- + +## R-009: CI/CD Pipeline Architecture + +**Decision**: GitHub Actions matrix strategy with `fail-fast: false`. Services defined +in `.github/services.json` as a JSON array. Shared logic for checkout, Docker login, +version tag extraction, and metadata is in the matrix job — matrix jobs inherit shared +steps via `needs` dependencies from a `setup` job that outputs the services matrix. + +**Tagging strategy**: `docker/metadata-action@v5` generates: +- Semver tags from git tags (`v1.2.3` → `1.2.3`, `1.2`, `1`) +- `latest` on default branch pushes +- Branch name tags for non-default branches + +**Health check**: After `docker/build-push-action@v5` with `push: false` (local build), +load image and run a service-specific smoke test. Only push if smoke test passes. + +**Adding a new service**: Add one JSON object to `.github/services.json`. Zero workflow +logic changes. + +**Key action versions** (current as of research date): +- `docker/setup-buildx-action@v3` +- `docker/build-push-action@v5` +- `docker/login-action@v3` +- `docker/metadata-action@v5` + +**Alternatives considered**: +- One workflow file per service — massive duplication, violates FR-030 +- Reusable workflow (workflow_call) — more complex than needed; matrix is sufficient + +--- + +## R-010: Monorepo Package Layout + +**Decision**: Plugin packages live in `plugins/` subdirectory, each as an independently +installable Python package with its own `pyproject.toml`. Plugin services that run as +standalone containers (OTEL, Xdebug) also have a `Dockerfile` in their directory. The +memory plugin's "service" is the third-party `mcp/neo4j-memory` image; its plugin +directory contains only the Python package code and deployment manifests. + +**Development installation**: +```bash +pip install -e . # CGC core +pip install -e plugins/cgc-plugin-otel +pip install -e plugins/cgc-plugin-xdebug +pip install -e plugins/cgc-plugin-memory +``` + +After this, `cgc --help` shows plugin commands automatically. + +**Production installation** (users who want only specific plugins): +```bash +pip install codegraphcontext # Core only +pip install codegraphcontext[otel] # Core + OTEL plugin (via extras) +pip install codegraphcontext[memory] # Core + memory plugin +``` + +This is achieved by declaring plugins as optional extras in the root `pyproject.toml`. diff --git a/specs/001-cgc-plugin-extension/spec.md b/specs/001-cgc-plugin-extension/spec.md new file mode 100644 index 00000000..5aceb21b --- /dev/null +++ b/specs/001-cgc-plugin-extension/spec.md @@ -0,0 +1,362 @@ +# Feature Specification: CGC Plugin Extension System + +**Feature Branch**: `001-cgc-plugin-extension` +**Created**: 2026-03-14 +**Status**: Draft +**Input**: Based on research in `cgc-extended-spec.md` — extend CGC to support runtime +memory and project knowledge layers via a plugin/addon pattern for CLI and MCP, with a +common CI/CD pipeline for Docker/K8s images. + +## User Scenarios & Testing *(mandatory)* + +### User Story 1 - Plugin Extensibility Foundation (Priority: P1) + +A CGC contributor or third-party developer wants to extend CGC with new capabilities +(new data sources, new MCP tools, new CLI commands) without modifying the core CGC +codebase. They build a self-contained addon package that declares its CLI commands and +MCP tools, publishes it separately, and CGC discovers and loads it automatically when +installed. + +**Why this priority**: All other stories depend on a functioning plugin system. Without +the foundation, the runtime, memory, and CI/CD stories cannot be independently developed +or released. This is the architectural backbone that makes the project composable. + +**Independent Test**: Install CGC core alone and verify it starts correctly. Then install +a minimal stub plugin; verify CGC discovers the plugin, the plugin's CLI command appears +in `cgc --help`, and its MCP tool appears in the MCP tool listing — without any changes +to core CGC code. + +**Acceptance Scenarios**: + +1. **Given** CGC core is installed without any plugins, **When** a user runs the CGC + CLI, **Then** only built-in core commands appear and no plugin-related errors occur. +2. **Given** a plugin package is installed in the same environment, **When** CGC starts, + **Then** the plugin's CLI commands and MCP tools are automatically available alongside + core capabilities. +3. **Given** a plugin is installed, **When** the plugin is uninstalled, **Then** CGC + starts cleanly without the plugin's commands or tools and without crashing. +4. **Given** two plugins are installed simultaneously, **When** CGC starts, **Then** + both plugins' commands and tools are available with no naming conflicts for distinct + plugins. +5. **Given** a plugin declares an incompatible version constraint, **When** CGC loads + plugins, **Then** the incompatible plugin is skipped with a clear warning stating the + version mismatch, and all compatible plugins still load. + +--- + +### User Story 2 - Runtime Intelligence via OTEL Plugin (Priority: P2) + +A backend developer running a PHP/Laravel application wants to understand what code +actually executes at runtime, not just what the static graph shows. They enable the +OTEL plugin, point their application's telemetry at the CGC OTEL endpoint, and can then +ask their AI assistant questions that combine runtime call data with static code +structure — for example, "which methods were called in the last hour that have no test +coverage" or "show the full execution path for a POST /api/orders request." + +**Why this priority**: The OTEL plugin is the highest-value runtime layer. It is +non-invasive (standard OTEL instrumentation already used in many projects), production- +safe, and delivers cross-layer queries immediately once spans flow into the graph. + +**Independent Test**: Start CGC with the OTEL plugin enabled. Send a sample trace (or +synthetic span payload) to the plugin's ingestion endpoint. Verify that the graph now +contains runtime nodes linked to static code nodes from a pre-indexed repository, and +that a cross-layer query returns meaningful results. + +**Acceptance Scenarios**: + +1. **Given** the OTEL plugin is enabled and a repository is indexed, **When** a + telemetry-instrumented application sends request traces, **Then** runtime call data + appears in the graph within 10 seconds of the request completing. +2. **Given** runtime nodes exist in the graph, **When** an AI assistant queries + "which methods ran during request X", **Then** the MCP tool returns a linked result + showing both the runtime call chain and the corresponding static code nodes. +3. **Given** a cross-service call occurs (service A calls service B), **When** spans + from both services are received, **Then** the graph contains an edge connecting the + two services and the call is queryable as a single path. +4. **Given** health-check or noise spans are received, **When** ingestion runs, **Then** + noise spans are filtered out and do not pollute the graph. +5. **Given** the OTEL plugin is disabled or not installed, **When** CGC starts, **Then** + no OTEL-related commands or tools appear and the core graph is unaffected. + +--- + +### User Story 3 - Development Traces via Xdebug Plugin (Priority: P3) + +A PHP developer debugging a complex feature wants method-level execution traces that +capture exactly which concrete class implementations ran (not just the interface), which +is information OTEL spans don't always provide. They enable the Xdebug listener plugin +in their development environment and selectively trigger traces for specific requests. +The resulting call-chain graph is linked back to CGC's static code nodes so they can +navigate from "what ran" to "where it's defined." + +**Why this priority**: This plugin is development/staging-only and requires Xdebug on +the target application, limiting its audience. It delivers deep, precise traces but is +not needed in production. It depends on the plugin foundation (P1) but is independent +of the OTEL plugin (P2). + +**Independent Test**: Start CGC with the Xdebug plugin enabled in development mode. +Trigger an Xdebug connection from a PHP process. Verify that stack frame nodes appear +in the graph linked to the corresponding static method nodes from a pre-indexed +repository. + +**Acceptance Scenarios**: + +1. **Given** the Xdebug plugin is enabled and a repository is indexed, **When** a PHP + process triggers an Xdebug trace, **Then** the full call stack appears in the graph + as linked frame nodes within 5 seconds of the trace completing. +2. **Given** the same call chain occurs repeatedly, **When** ingestion processes the + repeated traces, **Then** the graph contains deduplicated nodes (no duplicate chains) + and the repetition count is reflected rather than duplicated structure. +3. **Given** a frame resolves to a method that CGC has indexed, **When** the graph is + queried, **Then** the frame node is linked to the corresponding static method node, + enabling navigation from runtime execution to source definition. +4. **Given** the Xdebug plugin is not installed, **When** CGC starts, **Then** no + Xdebug-related commands or tools appear and no port is opened. + +--- + +### User Story 4 - Project Knowledge via Memory Plugin (Priority: P4) + +A developer or AI assistant wants to store and retrieve structured project knowledge +(specifications, decisions, research notes, known bugs) alongside the code graph. When +the memory plugin is enabled, the AI assistant can link stored knowledge entities to +specific classes or methods that CGC has indexed, enabling queries like "show me the +spec for the payment service and which methods implement it" or "which running code has +no associated specification." + +**Why this priority**: The memory plugin uses an existing third-party service with no +custom ingestion logic to build. It delivers high value (project knowledge linked to +code) with the lowest implementation cost of the three data-layer plugins. Its queries +are most powerful in combination with the static layer already provided by core CGC. + +**Independent Test**: Enable the memory plugin. Using the MCP tools it exposes, store a +knowledge entity describing a specific class that exists in an indexed repository. Query +for all classes that have associated knowledge entities and verify the stored entity +appears linked to the correct code node. + +**Acceptance Scenarios**: + +1. **Given** the memory plugin is enabled and a repository is indexed, **When** a user + stores a knowledge entity describing a class, **Then** the entity is linked to the + corresponding graph node and retrievable via an MCP tool query. +2. **Given** knowledge entities exist in the graph, **When** an AI assistant asks "which + code has no associated specification", **Then** the MCP tool returns the set of + indexed code nodes that have no memory entity linked to them. +3. **Given** the memory plugin is not installed, **When** CGC starts, **Then** no + memory-related commands or tools appear and the core graph is unaffected. + +--- + +### User Story 5 - Automated Container Builds via Common CI/CD Pipeline (Priority: P5) + +A maintainer releasing a new version of CGC or any plugin wants every service that +exposes an MCP endpoint to automatically build a versioned, production-ready container +image and publish it to a container registry. The build pipeline is shared across all +services (CGC core, OTEL plugin, Xdebug plugin, memory plugin), so adding a new plugin +service requires minimal CI configuration changes. The resulting images are compatible +with both Docker Compose and Kubernetes deployment patterns. + +**Why this priority**: The CI/CD pipeline enables reliable, reproducible deployment of +the plugin ecosystem. It is independent of the plugin system itself and can be delivered +after the plugins are working locally. It is foundational for anyone wanting to run +CGC-X in a self-hosted or homelab environment. + +**Independent Test**: Trigger the pipeline for a single service (CGC core or the OTEL +plugin). Verify that a tagged container image is built, passes a health-check smoke +test, and is published to the target registry with the correct version tag. Then verify +that the same pipeline configuration can build a second service with only a service +name change. + +**Acceptance Scenarios**: + +1. **Given** a version tag is pushed to the repository, **When** the pipeline runs, + **Then** container images for all enabled plugin services are built and published with + that version tag and a `latest` tag. +2. **Given** a plugin service container is started from its published image, **When** a + health check is performed, **Then** the service responds correctly within 30 seconds. +3. **Given** a new plugin service directory follows the shared conventions, **When** it + is added to the pipeline configuration, **Then** it builds and publishes alongside + existing services without changes to shared pipeline logic. +4. **Given** a build failure occurs in one service, **When** the pipeline runs, **Then** + only that service's build fails; other services complete successfully and their images + are published. +5. **Given** published images, **When** a Kubernetes manifest referencing those images + is applied to a cluster, **Then** the services start successfully and connect to their + configured graph database. + +--- + +### Edge Cases + +- What happens when a plugin depends on a specific graph schema version and the core has + been upgraded with schema changes? +- How does CGC handle a plugin that registers a CLI command name or MCP tool name + already used by another loaded plugin? +- What happens if the graph database is unavailable when a plugin attempts to write + ingested data? +- How does the system behave when the OTEL plugin receives a very high volume of spans + (burst traffic) that exceeds ingestion capacity? +- What happens when Xdebug sends stack frames for a file path that CGC has not indexed? +- How are sensitive values (database credentials, API keys) managed in container images + so they are never baked into the image layer? + +## Requirements *(mandatory)* + +### Functional Requirements + +**Plugin System Core** + +- **FR-001**: CGC MUST provide a plugin registration interface that allows independently + installable packages to declare CLI commands and MCP tools without modifying core code. +- **FR-002**: CGC MUST auto-discover installed plugins at startup and load them without + requiring manual configuration file edits. +- **FR-003**: CGC MUST isolate plugin failures so that a broken or incompatible plugin + does not prevent CGC core or other plugins from starting. +- **FR-004**: CGC MUST enforce plugin version compatibility checks and skip plugins that + declare an unsupported version range, reporting a clear diagnostic message. +- **FR-005**: CGC MUST ensure plugin-registered CLI commands appear in the top-level + help output, grouped under a visible "plugins" section or annotated as plugin-provided. +- **FR-006**: CGC MUST ensure plugin-registered MCP tools appear in the MCP tool listing + alongside core tools with their plugin source identified in metadata. + +**CLI Plugin Interface** + +- **FR-007**: The plugin interface MUST define a standard contract for registering CLI + command groups, including command name, arguments, options, and handler. +- **FR-008**: Plugins MUST be able to add new top-level CLI command groups without + conflicting with core command names. + +**MCP Plugin Interface** + +- **FR-009**: The plugin interface MUST define a standard contract for registering MCP + tools, including tool name, description, input schema, and handler function. +- **FR-010**: Plugins MUST be able to share the same graph database connection managed + by CGC core rather than opening independent connections. + +**OTEL Processor Plugin** + +- **FR-011**: The OTEL plugin MUST expose an ingestion endpoint that accepts telemetry + spans from a standard OpenTelemetry collector. +- **FR-012**: The OTEL plugin MUST extract structured runtime data from spans (service + identity, code namespace, called function, HTTP route, database query) and write it + to the graph as typed runtime nodes and relationships. +- **FR-013**: The OTEL plugin MUST attempt to correlate runtime nodes to existing static + code nodes in the graph where the function identity can be resolved. +- **FR-014**: The OTEL plugin MUST detect and represent cross-service calls as graph + edges between service nodes. +- **FR-015**: The OTEL plugin MUST support configurable span filtering to exclude + high-noise spans (health checks, metrics polling) from graph storage. +- **FR-016**: The OTEL plugin MUST expose at least one MCP tool that enables querying + the execution path for a specific request or route. + +**Xdebug Listener Plugin** + +- **FR-017**: The Xdebug plugin MUST expose a TCP listener that accepts DBGp protocol + connections from Xdebug-enabled PHP processes. +- **FR-018**: The Xdebug plugin MUST capture the full call stack on each trace event + and write stack frame nodes and call-chain relationships to the graph. +- **FR-019**: The Xdebug plugin MUST deduplicate identical call chains so repeated + execution of the same path does not create redundant graph structure. +- **FR-020**: The Xdebug plugin MUST attempt to resolve stack frames to static method + nodes already indexed by CGC core. +- **FR-021**: The Xdebug plugin MUST be configurable as a development/staging-only + service, excluded from production deployments without changing core configuration. + +**Memory Plugin** + +- **FR-022**: The memory plugin MUST expose MCP tools for storing, retrieving, updating, + and searching structured knowledge entities (specifications, decisions, research, + bugs, feature context). +- **FR-023**: The memory plugin MUST allow knowledge entities to be linked to specific + code nodes (classes, methods) already present in the graph. +- **FR-024**: The memory plugin MUST support full-text search across stored knowledge + entities via an MCP query tool. +- **FR-025**: The memory plugin MUST expose an MCP tool that returns all code nodes + lacking any associated knowledge entity, to identify undocumented code. + +**CI/CD Pipeline** + +- **FR-026**: The pipeline MUST build a versioned container image for each plugin + service when a version tag is pushed to the repository. +- **FR-027**: Container images MUST pass a basic health-check smoke test before being + published to the registry. +- **FR-028**: The pipeline MUST publish images with both a specific version tag and a + `latest` tag to the configured container registry. +- **FR-029**: A build failure in one service image MUST NOT prevent other service images + from completing their build and publish steps. +- **FR-030**: The pipeline MUST support a shared build configuration so that adding a + new plugin service requires only adding the service name to a list, not duplicating + pipeline logic. +- **FR-031**: Container images MUST NOT embed sensitive credentials; all secrets MUST + be provided at runtime via environment variables. +- **FR-032**: Each published image MUST include a container health-check definition that + verifies the service is ready to accept connections. +- **FR-033**: Published images MUST be compatible with Kubernetes pod specifications + (no host-mode networking requirements, configurable via environment variables only). + +### Key Entities + +- **Plugin**: A self-contained, independently installable package that contributes CLI + commands and/or MCP tools to CGC. Has a declared name, version, compatibility range, + and lists of registered commands and tools. +- **PluginRegistry**: The runtime component within CGC core that discovers, validates, + and loads installed plugins. Tracks which plugins are active and resolves conflicts. +- **CLICommand**: A command or command group contributed by a plugin. Has a name, + description, argument schema, and an executing handler. +- **MCPTool**: An MCP-protocol tool contributed by a plugin. Has a name, description, + input schema, and a handler. Source plugin is identified in its metadata. +- **RuntimeNode**: A graph node produced by the OTEL or Xdebug plugin representing an + observed execution event (span, stack frame). Carries a `source` property identifying + its origin layer. +- **KnowledgeEntity**: A structured project knowledge record (spec, decision, research, + bug, feature) stored by the memory plugin. Can be linked to static code nodes. +- **ContainerImage**: A versioned, publishable artifact for a plugin service.

Graph-First Architecture + +All code intelligence MUST be represented as a property graph of typed nodes (functions, +classes, files, modules) and typed relationships (CALLS, IMPORTS, INHERITS, DEFINES). +New parsers and indexers MUST produce graph-compatible output — flat or ad-hoc data +structures are not acceptable as the final output of any indexing step. +The graph schema (node labels, relationship types, and their required properties) is the +canonical source of truth; all CLI commands, MCP tools, and query logic MUST derive from +it, not duplicate or contradict it. + +**Rationale**: The entire value proposition of CGC is queryable graph context. Deviating +from graph-first design undermines the core product contract with AI agents and users. + +### II. Dual Interface — CLI and MCP + +Every user-facing capability MUST be accessible via both the `cgc` CLI (Typer/Click) and +the MCP server tool API. Neither interface may lag behind the other; a capability that +exists in one MUST exist in the other within the same release. CLI commands output to +stdout (human-readable by default, JSON when `--json` flag supplied); errors go to stderr. + +**Rationale**: Users rely on CGC in both interactive terminal sessions and automated AI +assistant pipelines. Parity between the two interfaces prevents feature silos and ensures +the tool is universally accessible regardless of integration context. + +### III. Testing Pyramid (NON-NEGOTIABLE) + +CGC follows a strict testing pyramid: + +- **Unit** (`tests/unit/`): Fast (<100ms), heavily mocked, covers isolated components. +- **Integration** (`tests/integration/`): Covers interaction between 2+ components with + partial mocking (~1s). +- **E2E** (`tests/e2e/`): Full user journey tests with minimal mocking (>10s). + +All new features MUST include tests at the appropriate pyramid level(s) before merging. +`./tests/run_tests.sh fast` (unit + integration) MUST pass locally before any PR is +submitted. Tests for a feature MUST be written and observed to fail before implementation +begins (Red-Green-Refactor). + +**Rationale**: CGC's correctness guarantees — that graph queries return accurate, complete +context — can only be trusted with comprehensive, layered test coverage. Untested parsers +or query paths create silent failures that degrade AI agent output quality. + +### IV. Multi-Language Parser Parity + +Every programming language supported by CGC MUST expose the same canonical node types +(Function, Class, File, Module, Variable) and the same relationship types (CALLS, IMPORTS, +INHERITS, DEFINES) where applicable to the language. Language-specific parsers MAY add +language-native relationship types (e.g., IMPLEMENTS for Java interfaces) only if they +are documented in the graph schema and do not break cross-language queries. A parser MUST +NOT introduce schema deviations (renamed labels, different property keys) without a +migration plan approved via the amendment process. + +**Rationale**: Users and AI agents query the graph without knowing which language produced +the data. Schema inconsistency across parsers would produce unreliable query results and +break tooling that depends on stable node/relationship contracts. + +### V. Simplicity + +Implement the simplest solution that satisfies the current requirement. YAGNI (You Aren't +Gonna Need It) applies strictly: abstractions, helpers, and new modules MUST be justified +by a current, concrete need — not anticipated future requirements. Three similar lines of +code are preferable to a premature abstraction. Complexity in the graph schema, parser +logic, or query layer MUST be justified in the plan document before implementation. + +**Rationale**: CGC serves a broad contributor base across many languages and stacks. +Unnecessary complexity raises the barrier to contribution, increases maintenance cost, and +makes the graph schema harder to reason about. + +## Technology Constraints + +CGC's core technology choices are stable and MUST NOT be replaced without a major +constitutional amendment: + +- **Language**: Python 3.10+ (no other implementation languages for the core library) +- **Parsing**: Tree-sitter (the sole AST parsing mechanism; regex-based parsing is + prohibited for language node extraction) +- **Protocol**: Model Context Protocol (MCP) for AI agent integration +- **Graph Database**: FalkorDB (embedded/default) or Neo4j (production); the database + abstraction layer MUST support both without feature disparity +- **CLI Framework**: Typer / Click +- **Package Distribution**: PyPI (`codegraphcontext`) + +New runtime dependencies MUST be added to `pyproject.toml` (or equivalent) and MUST be +justified in the PR description. Dependencies that significantly increase install size or +reduce cross-platform compatibility require explicit maintainer approval. + +## Contribution Standards + +All contributors MUST adhere to the following standards: + +- **Code style**: Follow existing project conventions; run linting before submitting. +- **PR scope**: Each pull request MUST be focused on a single feature or bug fix. +- **Test gate**: `./tests/run_tests.sh fast` MUST pass before PR submission. +- **Documentation**: New CLI commands and MCP tools MUST be documented in `docs/`. +- **Security**: Vulnerabilities MUST be reported privately (see `SECURITY.md`); do not + open public issues for security findings. Dependencies MUST be kept up to date. +- **Breaking changes**: Any change to the graph schema, CLI command signatures, or MCP + tool API signatures is a breaking change and requires a MAJOR version bump and a + migration guide. + +## Governance + +This constitution supersedes all other development practices documented in this repository. +In the event of a conflict between this document and any other guideline, this constitution +takes precedence. + +**Amendment procedure**: +1. Open a GitHub issue proposing the amendment with rationale. +2. Allow at least one maintainer review cycle. +3. Update this file, increment the version per the versioning policy, and set + `Last Amended` to the date of the change. +4. Propagate changes to dependent templates (per the Consistency Propagation Checklist + in `.specify/templates/constitution-template.md`). + +**Versioning policy**: +- MAJOR: Backward-incompatible governance changes, principle removals, or redefinitions. +- MINOR: New principle or section added, or materially expanded guidance. +- PATCH: Clarifications, wording fixes, non-semantic refinements. + +**Compliance review**: All PRs MUST be reviewed against Core Principles I–V. Reviewers +MUST reject PRs that violate any non-negotiable principle without documented justification +in a Complexity Tracking section (see plan template). + +**Version**: 1.0.0 | **Ratified**: 2025-08-17 | **Last Amended**: 2026-03-14 diff --git a/.specify/scripts/bash/check-prerequisites.sh b/.specify/scripts/bash/check-prerequisites.sh new file mode 100755 index 00000000..6f7c99e0 --- /dev/null +++ b/.specify/scripts/bash/check-prerequisites.sh @@ -0,0 +1,190 @@ +#!/usr/bin/env bash + +# Consolidated prerequisite checking script +# +# This script provides unified prerequisite checking for Spec-Driven Development workflow. +# It replaces the functionality previously spread across multiple scripts. +# +# Usage: ./check-prerequisites.sh [OPTIONS] +# +# OPTIONS: +# --json Output in JSON format +# --require-tasks Require tasks.md to exist (for implementation phase) +# --include-tasks Include tasks.md in AVAILABLE_DOCS list +# --paths-only Only output path variables (no validation) +# --help, -h Show help message +# +# OUTPUTS: +# JSON mode: {"FEATURE_DIR":"...", "AVAILABLE_DOCS":["..."]} +# Text mode: FEATURE_DIR:... \n AVAILABLE_DOCS: \n ✓/✗ file.md +# Paths only: REPO_ROOT: ... \n BRANCH: ... \n FEATURE_DIR: ... etc. + +set -e + +# Parse command line arguments +JSON_MODE=false +REQUIRE_TASKS=false +INCLUDE_TASKS=false +PATHS_ONLY=false + +for arg in "$@"; do + case "$arg" in + --json) + JSON_MODE=true + ;; + --require-tasks) + REQUIRE_TASKS=true + ;; + --include-tasks) + INCLUDE_TASKS=true + ;; + --paths-only) + PATHS_ONLY=true + ;; + --help|-h) + cat << 'EOF' +Usage: check-prerequisites.sh [OPTIONS] + +Consolidated prerequisite checking for Spec-Driven Development workflow. + +OPTIONS: + --json Output in JSON format + --require-tasks Require tasks.md to exist (for implementation phase) + --include-tasks Include tasks.md in AVAILABLE_DOCS list + --paths-only Only output path variables (no prerequisite validation) + --help, -h Show this help message + +EXAMPLES: + # Check task prerequisites (plan.md required) + ./check-prerequisites.sh --json + + # Check implementation prerequisites (plan.md + tasks.md required) + ./check-prerequisites.sh --json --require-tasks --include-tasks + + # Get feature paths only (no validation) + ./check-prerequisites.sh --paths-only + +EOF + exit 0 + ;; + *) + echo "ERROR: Unknown option '$arg'.

e2e-tests.yml: add FalkorDB service container with health check, bump checkout@v3->v4 and setup-python@v4->v5, add cache: pip, expose FALKORDB_HOST/FALKORDB_PORT/DATABASE_TYPE env vars for test runner - macos.yml: replace || true shell suppression with continue-on-error: true on Install system deps, Run index, and Try find steps - test-plugins.yml: remove silent pip fallback from core install step so broken installs fail fast instead of silently proceeding with partial deps -

The PluginRegistry calls ep.load() and reads PLUGIN_METADATA, get_plugin_commands, get_mcp_tools, and get_mcp_handlers off the returned object as module attributes — so loading always failed. Fix: remove the colon-attribute suffix so each entry point resolves to the package module (e.g. cgc_plugin_stub). Add re-exports of get_plugin_commands, get_mcp_tools, and get_mcp_handlers from the cli/mcp_tools submodules into each plugin's __init__.py so the registry finds them on the loaded module.
