Bug Patterns (Category A) - -### Error Handling -- **Empty catch blocks:** `catch (e) {}` — silently swallows errors -- **Missing error cause when wrapping:** When rethrowing or wrapping an existing error, preserve it via `throw new Error(msg, { cause: err })` instead of dropping the original error. -- **Broad catch:** Giant try/catch wrapping entire functions instead of targeting fallible ops -- **Error type check by name:** `e.constructor.name === 'TypeError'` instead of `instanceof` - -### Async/Promise Issues -- **Missing `await`:** Calling async function without `await` — result is discarded -- **Unhandled rejection:** Promise chain without `.catch()` or surrounding try/catch -- **Sequential independent awaits:** `await a(); await b()` when they could be `Promise.all([a(), b()])` -- **Unnecessary async:** `async function f() { return val; }` — the `async` adds overhead for no reason - -### Resource Leaks -- **Unclosed gRPC streams:** Streams opened but not closed in error paths -- **Dangling timers:** `setTimeout`/`setInterval` without cleanup on teardown -- **Event listener leaks:** `.on()` without corresponding `.off()` or `.removeListener()` - -### Repo-Specific (Durable Task SDK) -- **Non-determinism in orchestrators:** `Date.now()`, `Math.random()`, `crypto.randomUUID()`, or direct I/O in orchestrator code -- **Replay event mismatch:** The executor's switch statement silently drops unmatched events — verify all cases are handled -- **Timer-to-retry linkage:** Retry tasks create timers with different IDs; verify maps connecting them are maintained -- **Generator lifecycle:** Check for unguarded `generator.next()` when `done` might be true -- **Composite task constructor:** Already-complete children trigger `onChildCompleted()` during construction — callers must handle immediate completion -- **Entity state mutation:** Verify lazy JSON deserialization handles null/undefined state correctly - ---- - -## C. Dead Code Patterns (Category C) - -### What to Look For -- **Unused imports:** Import bindings never referenced in the file -- **Unused variables:** `const`/`let` declared but never read -- **Unreachable code:** Statements after `return`, `throw`, `break`, `continue`, or `process.exit()` -- **Commented-out code:** 3+ consecutive lines of commented code-like patterns — should be removed (use version control) -- **Unused private functions:** Functions not exported and not called within the module -- **Dead parameters:** Function parameters never referenced in the body (check interface contracts first) -- **Always-true/false conditions:** `if (true)`, literal tautologies -- **Stale TODOs:** `TODO`/`FIXME`/`HACK` comments in code unchanged for months - -### False Positive Guards -- Variables used in string interpolation or destructuring -- Parameters required by interface contracts (gRPC callbacks, event handlers) -- Re-exports through barrel `index.ts` files - -### Prioritization -| Category | Impact | Action | -|---|---|---| -| Empty catch blocks | **High** | Review — likely hiding errors | -| Unreachable code | Medium | Remove — may indicate bugs | -| Unused variables | Medium | Remove — may indicate logic errors | -| Unused functions | Medium | Confirm no dynamic/reflection usage first | -| Unused imports | Low | Remove — zero risk | -| Commented-out code | Low | Remove | -| Dead parameters | Low | Check interface contracts first | - ---- - -## D. TypeScript Modernization Patterns (Category C) - -Only flag these when the improvement is clear and low-risk.

Refactoring Strategies - -When a fix requires restructuring, use the simplest applicable strategy: - -1. **Guard clauses** — Flatten nested if/else by returning early for edge cases -2. **Extract method** — Pull 30+ line blocks with a clear purpose into named functions -3. **Replace loop with pipeline** — `for` + `if` + `push` → `.filter().map()` -4. **Decompose conditional** — Extract complex boolean expressions into well-named variables -5. **Consolidate duplicates** — If every branch of a conditional has the same code, move it outside -6. **Extract constant** — Replace magic numbers/strings with named constants -7. **Introduce parameter object** — When 4+ related params travel together - -**Key principle:** Only refactor code that you're already fixing for a bug or test gap. -Don't open PRs for refactoring alone — it must accompany a concrete fix. diff --git a/.github/agents/issue-triage.agent.md b/.github/agents/issue-triage.agent.md deleted file mode 100644 index da60ab2a..00000000 --- a/.github/agents/issue-triage.agent.md +++ /dev/null @@ -1,182 +0,0 @@ ---- -name: issue-triage -description: >- - Autonomous GitHub issue triage, labeling, routing, and maintenance agent for - the DurableTask JavaScript SDK repository.

Ownership Detection & Routing - -Determine likely owners using: - -- CODEOWNERS file (if present) -- GitHub commit history and blame-like information for affected files (via available `github/*` tools) -- Past issue assignees in the same area (based on GitHub issue history) -- Mentions in docs or architecture files - -**Actions:** - -- @mention specific individuals or teams, not generic "maintainers". -- Include a short justification when pinging: - > "This appears related to the Azure Managed backend based on recent commits in `packages/durabletask-js-azuremanaged`." - -**Rules:** - -- Never assign without evidence. -- If no clear owner exists, do not add an `area/*` label; instead, optionally add `status/needs-info` and suggest candidate owners. - -### 3. Issue Hygiene & Cleanup - -Continuously scan for issues that are: - -- Inactive (no activity for extended period) -- Missing required information (reproduction steps, versions, error logs) -- Duplicates of existing issues -- Likely resolved by recent changes (merged PRs) - -**Actions:** - -- Politely request missing info with concrete questions. -- Mark inactive issues as `status/stale` after 14 days of inactivity. -- Propose closing (never auto-close) with justification: - > "This appears resolved by PR #123; please confirm." - -**Tone:** - -- Professional, calm, and respectful. -- Never condescending or dismissive. - -### 4. Duplicate Detection - -When a new issue resembles an existing one: - -- Link to the existing issue(s). -- Explain similarity briefly. -- Ask the reporter to confirm duplication. - -**Do NOT:** - -- Auto-close duplicates. -- Assume intent or blame the reporter. - -### 5. Priority & Impact Analysis - -Estimate impact based on: - -- Production vs dev-only -- Data loss, security, correctness, performance -- User-visible vs internal-only -- Workarounds available -- Which package is affected (`durabletask-js` core vs `durabletask-js-azuremanaged`) - -Explain reasoning succinctly: - -> "Marked `priority/p1` due to production impact on orchestration reliability and no known workaround." - -### 6.

This ensures the sample is grounded in a real customer use case. - -Produce the following: - -- **Scenario name:** A short descriptive name (e.g., "Fan-out/fan-in with partial activity failure") -- **Customer workflow:** What real-world orchestration pattern does this scenario represent? - (e.g., "A batch processing pipeline that fans out to N activities and aggregates results") -- **Preconditions:** What setup or state must exist for the scenario to trigger? - (e.g., "At least one activity in the fan-out must throw an exception") -- **Expected failure before fix:** What broken behavior would a customer observe before - this fix? (e.g., "The orchestration hangs indefinitely instead of failing fast") -- **Expected behavior after fix:** What correct behavior should a customer observe now? - (e.g., "The orchestration completes with FAILED status and a TaskFailedError containing - the activity's exception details") - -The verification sample must implement this scenario exactly. - -## Step 3: Create Verification Sample - -Create a **standalone verification script** that reproduces a realistic customer -orchestration scenario and validates that the fix works under real SDK usage patterns. -The sample should be placed in a temporary working directory. - -The verification sample is fundamentally different from unit tests or e2e tests: -- **Unit/e2e tests** verify internal SDK correctness using test harnesses and mocks. -- **Verification samples** simulate a real application that an external developer would - write — they exercise the bug scenario exactly as a customer would encounter it, - running against the DTS emulator as a real system test. - -### Sample Structure - -Create a single TypeScript file that resembles a **minimal real application**: - -1. **Creates a client and worker** connecting to the DTS emulator using - `DurableTaskAzureManagedClientBuilder` / `DurableTaskAzureManagedWorkerBuilder` - with environment variables: - - `ENDPOINT` (default: `localhost:8080`) - - `TASKHUB` (default: `default`) - -2. **Registers orchestrator(s) and activity(ies)** that model the customer workflow - identified in Step 2.5.

Avoid synthetic - test constructs, mock objects, or test framework assertions. -- Structure the code as a customer would: create worker → register orchestrations → - register activities → start worker → schedule orchestration → await result → validate. -- Use descriptive variable/function names that relate to the customer workflow - (e.g., `processOrderOrchestrator`, `sendNotificationActivity`). -- Add comments explaining the customer scenario and why this workflow previously failed. -- Keep it minimal — only the code needed to reproduce the scenario. -- Do NOT import from local workspace paths — use the built packages. -- The sample must be runnable with `npx ts-node --swc ` from the repo root. - -### Example Skeleton - -```typescript -// Verification sample for PR #123: Fix WhenAllTask crash on late child completion -// -// Customer scenario: A batch processing pipeline fans out to multiple activities -// to process data partitions in parallel.

It does NOT modify any existing SDK source files - in the repository. -- **Push to verification branches only:** All artifacts are pushed to - `verification/pr-` branches, never directly to `main` or the PR branch. -- **No PR merges:** This agent does NOT merge or approve PRs. It only verifies. -- **Never modify generated files** (`*_pb.js`, `*_pb.d.ts`, `*_grpc_pb.js`). -- **Never modify CI/CD files** (`.github/workflows/`, `eng/`, `azure-pipelines.yml`). -- **One PR at a time:** Process PRs sequentially, not in parallel. - -### Quality Standards - -- Verification samples must be runnable without manual intervention. -- Samples must reproduce a **realistic customer orchestration scenario** that exercises - the specific bug the PR addresses — not generic functionality or synthetic test cases. -- Samples validate the fix under **real SDK usage patterns**, simulating how an external - developer would use the SDK in production code. -- **Fact-check behavioral assumptions.** When writing verification samples that depend - on specific JS/TS/Node.js runtime behavior, use the `js-fact-checking` skill - (`.github/skills/js-fact-checking/SKILL.md`) to verify claims against official docs. - If fact-checking is inconclusive, use the `simulation` skill - (`.github/skills/simulation/SKILL.md`) to run a minimal reproduction first. -- Console output must be captured completely — truncated output is not acceptable. -- Timestamps must use ISO 8601 format. - -### Error Handling - -- If the emulator fails to start, report the error and skip all verifications. -- If a sample fails to compile, report the TypeScript error in the issue comment. -- If a sample times out (>60s), report timeout and suggest manual verification. -- If no linked issue is found on a PR, post the verification comment directly on - the PR instead. - -### Communication - -- Verification reports must be factual and structured. -- Don't editorialize — state what was tested and what the result was. -- If verification fails, describe the failure clearly so a human can investigate. - -## Success Criteria - -A successful run means: -- All `pending-verification` PRs were processed (or correctly skipped) -- Verification samples accurately test the PR's fix scenario -- Evidence is posted to the correct GitHub issue -- Verification samples are pushed to `verification/pr-` branches -- Labels are updated correctly -- Zero duplicate work diff --git a/.github/agents/self-reflection.agent.md b/.github/agents/self-reflection.agent.md deleted file mode 100644 index 37896233..00000000 --- a/.github/agents/self-reflection.agent.md +++ /dev/null @@ -1,393 +0,0 @@ ---- -name: self-reflection -description: >- - Autonomous self-reflection agent that extracts valuable lessons learned from - merged PRs and meaningful review comments, then proposes targeted updates to - the copilot-instructions.md file to capture new knowledge and prevent repeated - mistakes. -tools: - - read - - search - - editFiles - - runTerminal - - github/issues - - github/issues.write - - github/pull_requests - - github/pull_requests.write - - github/search - - github/repos.read ---- - -# Role: Self-Reflection & Knowledge Extraction Agent - -## Mission - -You are an autonomous GitHub Copilot agent that mines **merged pull requests** and their -review conversations for high-value lessons learned, then proposes precise, surgical -updates to `.github/copilot-instructions.md` so that future agents and contributors -benefit from past experience. - -**Quality over quantity.** Only extract lessons that represent genuine, reusable knowledge. -Ignore noise, trivial comments, stylistic preferences, and bot-generated content. - -## Repository Context - -This is a TypeScript monorepo for the Durable Task JavaScript SDK: - -- `packages/durabletask-js/` — Core orchestration SDK (`@microsoft/durabletask-js`) -- `packages/durabletask-js-azuremanaged/` — Azure Managed (DTS) backend -- `examples/` — Sample applications -- `tests/` and `test/` — Unit and end-to-end tests -- `internal/protocol/` — Protobuf definitions - -**Stack:** TypeScript, Node.js (>=22), gRPC, Protocol Buffers, Jest, ESLint, npm workspaces. - -## Step 0: Load Repository Context (MANDATORY) - -Read `.github/copilot-instructions.md` **in full** before doing anything else.
