Read this section before doing any work — -using these tools cuts round-trips, eliminates guessing, and prevents the -most common failure modes. - -### Always prefer structured output (`--json`) - -`--json` is the contract between agents and the CLI. Every command -that produces structured output honors it. Text output is for humans; -JSON is the stable machine-readable shape, versioned as API. - -**Flag position.** `--json` is a persistent flag on the root command, -so both positions are valid: - -```bash -gofasta --json verify # before the subcommand -gofasta verify --json # after — equivalent -``` - -**Output modes.** Two shapes, depending on the command: - -1. **Single document.** One JSON object or array on stdout, followed - by a newline. Parse with `jq`, `json.Unmarshal`, etc. This is the - default for every introspection + workflow command. - - ```bash - gofasta routes --json | jq '.[] | select(.method == "POST") | .path' - gofasta verify --json | jq '.checks[] | select(.status == "fail")' - gofasta inspect User --json | jq '.service_methods[].name' - gofasta status --json | jq '.checks[] | select(.status == "drift")' - gofasta ai list --json - gofasta do list --json - gofasta g scaffold Invoice total:float --dry-run --json | jq '.planned_files' - ``` - -2. **NDJSON (newline-delimited).** One JSON object per line, emitted - as events happen. Used by long-running commands that stream - progress. `gofasta dev --json` is the main example — it emits - `preflight`, `service`, `migrate`, `air`, and `shutdown` events in - sequence: - - ```bash - # Watch for the first service to go unhealthy and react immediately: - gofasta dev --json | jq -c 'select(.event=="service" and .status=="unhealthy")' - - # Wait until the HTTP server reports ready, then exit the tail: - gofasta dev --json | jq -c 'select(.event=="air" and .status=="running")' | head -1 - ``` - -**Exit codes.** `--json` does NOT suppress exit codes. A failing -command still exits non-zero; the JSON on stderr tells you why. -Always branch on the exit code first, then read the error payload: - -```bash -if ! gofasta verify --json > result.json 2> error.json; then - jq -r '.code' error.json # e.g. "GO_TEST_FAILED" - jq -r '.hint' error.json # remediation in one line - exit 1 -fi -``` - -**Stream separation.** Success output goes to **stdout**; errors go -to **stderr**. Never mix them. If you need only the failure payload, -redirect stdout to `/dev/null`: - -```bash -gofasta verify --json 2> err.json 1> /dev/null || jq -r '.code' err.json -``` - -**Error shape.** Every error in `--json` mode serializes as: - -```json -{ - "code": "WIRE_MISSING_PROVIDER", - "message": "undefined: NewOrderProvider", - "hint": "add NewOrderProvider to app/di/providers/order.go and run `gofasta wire`", - "docs": "https://gofasta.dev/docs/cli-reference/wire" -} -``` - -Pattern-match on `code` (stable API, never renamed). The `hint` is -the exact remediation. The `docs` URL is the most relevant reference. - -**Stable contract.** Field names and types are stable API across -releases. Adding new fields is a compatible change agents should -tolerate (parse with `jq` / unmarshal into structs that ignore -unknown fields). Renaming or removing a field follows a deprecation -cycle and is called out in release notes. - -**`--dry-run` + `--json`.** Destructive commands accept `--dry-run` to -preview actions without touching disk. Combine with `--json` to get a -structured preview — extremely useful before scaffolding or workflow -runs: - -```bash -gofasta g scaffold Invoice total:float --dry-run --json - # → { "planned_files": [...], "planned_patches": [...], ... } - -gofasta do new-rest-endpoint Invoice total:float --dry-run --json - # → { "workflow": "...", "steps": [{command, args, ...}], ... } - -gofasta ai claude --dry-run --json - # → { "agent": "claude", "files_to_write": [...], ... } -``` - -**Which commands support `--json` (non-exhaustive):** - -| Category | Commands | -|---|---| -| Introspection | `routes`, `inspect `, `config schema`, `status`, `version`, `doctor` | -| Quality gates | `verify`, `do health-check` | -| Generators (dry-run + result) | `g scaffold`, `g model`, `g service`, `g controller`, `g job`, `g task`, … | -| Workflows | `do `, `do list` | -| AI installer | `ai list`, `ai status`, `ai ` | -| Dev server (NDJSON) | `dev` | -| Deploy | `deploy status`, `deploy` (NDJSON steps) | - -Run any command with `--help` to confirm exact semantics. When in -doubt, pass `--json` — commands without structured output simply -ignore it. - -### Parse error codes, not error text - -Every CLI error carries four fields when emitted in `--json` mode: - -```json -{ - "code": "WIRE_MISSING_PROVIDER", - "message": "undefined: NewOrderProvider", - "hint": "add NewOrderProvider to app/di/providers/order.go and run `gofasta wire`", - "docs": "https://gofasta.dev/docs/cli-reference/wire" -} -``` - -Pattern-match on the **`code`** (stable across releases) rather than -regex-parsing the message.

The full list lives in the error-code registry at -`https://gofasta.dev/docs/cli-reference/verify` and related pages. - -### Understand a resource before modifying it - -When asked to change an existing resource (e.g. "add a `SoftArchive` -method to `Order`"), **run `gofasta inspect ` first**. It -AST-parses the model, DTOs, service interface, controller methods, and -routes, emitting the whole resource shape as one structured document. -Replaces opening six files and guessing. - -```bash -gofasta inspect Order --json -``` - -Reveals: -- Every field in the model -- Every DTO type declared for the resource -- Every service-interface method signature -- Every controller method signature -- Every registered route - -Equivalent to reading `app/models/order.model.go` + `app/dtos/order.dtos.go` -+ `app/services/interfaces/order_service.go` + `app/rest/controllers/order.controller.go` -+ `app/rest/routes/order.routes.go` — but in one call, in a shape that -parses cleanly. - -### Check for drift before making changes - -`gofasta status` is the offline "is this project in a clean state?" -check. It reports when derived artifacts (Wire, Swagger) are out of -sync with their inputs, when migrations are pending, and when -regenerated files show up as uncommitted in git. Run it when entering -the project cold — if anything reports `drift`, fix it before starting -work so your own changes don't mix with unrelated staleness. - -```bash -gofasta status # one-glance drift report -gofasta status --json # structured consumption -``` - -### Use workflows to avoid multi-round-trip command chains - -When a task requires multiple gofasta commands in sequence, use -`gofasta do ` instead of invoking each command separately. -Fewer tool calls, stable atomic contract, transparent step list. - -```bash -gofasta do list # every workflow -gofasta do new-rest-endpoint Invoice total:float # scaffold + migrate up + swagger -gofasta do rebuild # wire + swagger -gofasta do clean-slate # db reset + seed -gofasta do health-check # verify + status -``` - -Pass `--dry-run` to preview the chain without executing. Use -`--json` to get a structured `{workflow, steps[], status, duration_ms}` -result. - -### Validate config edits against the schema - -When editing `config.yaml`, generate the schema first to know what keys -and values are valid — don't guess from memory, and don't trust training -data (it may be stale): - -```bash -gofasta config schema > /tmp/config.schema.json -# validate your proposed config edit against the schema before writing -ajv validate -s /tmp/config.schema.json -d config.yaml -``` - -The schema is emitted by a project-local helper (`./cmd/schema`) so it -always matches the exact `gofasta` version pinned in `go.mod` — no -version skew between the CLI and the library your project uses. - -### Use the right generator, not hand-written CRUD - -Before writing any CRUD code by hand, check whether a `gofasta g *` -generator produces the right starting point. The scaffold auto-wires -every layer (DI container, routes index, `cmd/serve.go`) and runs -`go build ./...` after generation to catch template regressions -immediately. See the "Code generation" table below. - -If unsure what a generator would produce, run it with `--dry-run` — -every file it would create and every patch it would apply is printed -without touching disk. - -```bash -gofasta g scaffold Invoice total:float --dry-run -``` - -### One command to verify your work - -The single most important command for agents: **`gofasta verify`**. -Runs gofmt, `go vet`, `golangci-lint`, `go test -race`, `go build`, -Wire drift check, and routes sanity — in one invocation. Run it -**before** claiming any task is done. `--json` output gives -per-check status so you can pinpoint failures: - -```bash -gofasta verify --json | jq '.checks[] | select(.status == "fail")' -``` - -Wrap in `gofasta do health-check` to also run `gofasta status` -(drift detection) at the same time. - -### Debug a failing request without guesswork - -When a test fails, an endpoint returns the wrong status, or a request -is slow and you can't tell why, **do not grep through logs**. The -scaffold ships a devtools package that captures structured runtime -state (requests, SQL with bound vars, trace spans with call-stack -snapshots, slog records, cache ops, panics), and the CLI exposes -every surface as a first-class `gofasta debug ` — -agent-friendly, `--json`-native, no port or URL guessing required. - -`gofasta dev` sets the `devtools` build tag automatically so the -endpoints are live. In production builds the same package compiles -to no-ops — zero debug surface. - -#### The `gofasta debug` command family - -Every command below honors `--json` (stable API) and the global -`--app-url` override. Run `gofasta debug --help` for flag -details. Exit codes are meaningful: `DEBUG_APP_UNREACHABLE` (app not -running), `DEBUG_DEVTOOLS_OFF` (production build — rebuild under -`gofasta dev`), `DEBUG_TRACE_NOT_FOUND`, `DEBUG_BAD_FILTER`, -`DEBUG_BAD_DURATION`. - -| Command | Purpose | -|---|---| -| `gofasta debug health` | Probe the app + every `/debug/*` surface; reports reachability + devtools state. First call after `gofasta dev`. | -| `gofasta debug requests` | List captured requests. Filters: `--trace`, `--method`, `--status=2xx\|5xx\|400-499`, `--path`, `--slower-than=100ms`, `--limit`. | -| `gofasta debug sql` | List captured SQL. Filters: `--trace`, `--slower-than`, `--contains`, `--errors-only`, `--limit`. | -| `gofasta debug traces` | List completed trace summaries. Filters: `--slower-than`, `--status=ok\|error`, `--limit`. | -| `gofasta debug trace ` | Full waterfall for one trace — spans, durations, parent-child nesting. Add `--with-stacks` for the captured call frames. | -| `gofasta debug logs --trace=` | Slog records for a specific trace. Filters: `--level`, `--contains`. | -| `gofasta debug errors` | Recent recovered panics with stacks and originating requests. | -| `gofasta debug cache` | Cache ops with hit/miss status and a hit-rate footer. Filters: `--trace`, `--op`, `--miss-only`. | -| `gofasta debug goroutines` | Live goroutines grouped by top-of-stack. Filters: `--filter=`, `--min-count`. | -| `gofasta debug n-plus-one` | Detected N+1 patterns in the recent SQL ring — one row per `(trace, template)` with ≥3 hits. | -| `gofasta debug explain ` | Run EXPLAIN against a captured SELECT via the app's registered GORM handle. Takes `--vars`. | -| `gofasta debug last-slow-request` | **Composed**: latest request ≥ `--threshold=200ms` + its trace + logs + SQL + N+1 findings, bundled as one JSON payload. | -| `gofasta debug last-error` | **Composed**: most recent panic + its trace + logs in one call. | -| `gofasta debug watch` | NDJSON stream of new events. Channels: `--requests` + `--errors` by default, `--sql`, `--cache`, `--trace` opt-in. | -| `gofasta debug profile ` | Download a pprof profile. Kinds: cpu, heap, goroutine, mutex, block, allocs, threadcreate, trace. | -| `gofasta debug har` | Export the request ring as HAR 1.2 JSON (import into Chrome DevTools / Insomnia / Postman). | - -#### Typical agent workflows - -**A slow endpoint.** One call returns everything: - -```bash -gofasta debug last-slow-request --threshold=200ms --json -``` - -The bundled JSON has `request`, `trace` (waterfall), `logs`, `sql`, -and `n_plus_one`. Parse with `jq` — no follow-up fetches needed. - -**A failing endpoint.** Same shape, for the most recent panic: - -```bash -gofasta debug last-error --json -``` - -**Live triage.** Stream new requests + errors as they happen: - -```bash -gofasta debug watch --requests --errors --json | jq -c 'select(.status >= 500)' -``` - -**Targeted inspection.** When you know the trace ID: - -```bash -gofasta debug trace # waterfall -gofasta debug logs --trace= # request logs -gofasta debug sql --trace= # request SQL -gofasta debug cache --trace= # request cache ops -``` - -**N+1 hunt.** After reproducing the slow request: - -```bash -gofasta debug n-plus-one --json -``` - -**EXPLAIN on demand.** Once you've found a suspect SELECT: - -```bash -sql=$(gofasta debug sql --limit=1 --json | jq -r '.[0].sql') -vars=$(gofasta debug sql --limit=1 --json | jq -r '.[0].vars[]?') -gofasta debug explain "$sql" --vars "$vars" -``` - -**Leak investigation.** Goroutines grouped by function: - -```bash -gofasta debug goroutines --min-count=10 -``` - -**Deeper profiling.** Capture a 30s CPU profile and open with pprof: - -```bash -gofasta debug profile cpu --duration=30s -o cpu.pprof -go tool pprof -http=:8090 cpu.pprof -``` - -**Share a repro.** Export HAR and attach to a bug report: - -```bash -gofasta debug har -o bug.har -``` - -The dashboard at `localhost:9090` renders all of this visually, but -the `gofasta debug` commands are the stable, scriptable interface -agents should prefer.

Ctrl+C tears it all down. | - -#### `gofasta dev` flags - -`gofasta dev` is the one-command dev loop. Every flag below is additive and orthogonal — combine them freely. - -| Flag | Purpose | -|---|---| -| `--no-services` | Skip all compose orchestration; just run Air (project has its own DB) | -| `--no-db` / `--no-cache` / `--no-queue` | Skip individual service classes by name-heuristic | -| `--services=` | Comma-separated explicit list (overrides `--no-*` flags) | -| `--profile=` | Pass through to `docker compose --profile` (e.g. `cache`, `queue`) | -| `--no-migrate` | Skip `migrate up` after services become healthy | -| `--no-teardown` | Leave compose services running on exit | -| `--keep-volumes` | Preserve named volumes on teardown (default `true`). Pass `--keep-volumes=false` for `down -v` instead of `stop`. | -| `--fresh` | Drop every compose volume before starting — forces a clean DB state | -| `--wait-timeout=` | Healthcheck wait timeout (default `30s`) | -| `--env-file=` | Alternate env file (default `.env`) | -| `--port=` | Override `PORT` env var | -| `--rebuild` | Delete Air's `tmp/` cache before starting so the next build is fresh | -| `--seed` | Run seeders after migrations | -| `--dry-run` | Print the resolved plan and exit (no side effects) | -| `--attach-logs` | Stream `docker compose logs -f` alongside Air output | -| `--dashboard` | Start the local dev dashboard (HTML debug page on `:9090` by default) | -| `--dashboard-port=` | Port for `--dashboard` | -| `--json` | Structured NDJSON events instead of human log lines (inherited from root) | - -**Structured output.** `gofasta dev --json` emits one event per line: `preflight`, `service` (with `starting` / `healthy` / `unhealthy` status), `migrate`, `air`, `shutdown`. Agents and CI pipelines branch on the `event` field rather than string-matching log output. - -**Error codes.** Failures during the dev pipeline return one of `DEV_DOCKER_UNAVAILABLE`, `DEV_COMPOSE_NOT_FOUND`, `DEV_SERVICE_UNHEALTHY`, `DEV_MIGRATION_FAILED`, `DEV_AIR_NOT_INSTALLED`, or `DEV_PORT_IN_USE`. Each carries a specific remediation hint in the JSON error payload. - -### Testing - -| Command | What it does | -|---|---| -| `go test ./...` | Run all tests | -| `go test -race ./...` | Run with the race detector (required before commit) | -| `make test` | Project's configured test target | - -### Code generation - -These are the workhorse commands. Prefer them over writing CRUD by hand: - -| Command | What it generates | -|---|---| -| `gofasta g scaffold Product name:string price:float` | Full REST resource — model, migration, repository, service, DTOs, controller, routes, Wire provider. Auto-wires into the DI container, routes index, and `cmd/serve.go`. | -| `gofasta g model Product name:string` | Model + migration only | -| `gofasta g service Product name:string` | Model + repository + service + DTOs | -| `gofasta g controller Product name:string` | Full REST stack for existing service | -| `gofasta g migration AddIndexToUsers` | Empty migration pair | -| `gofasta g job cleanup-tokens "0 0 * * *"` | Scheduled cron job | -| `gofasta g task send-welcome-email` | Async task handler (asynq) | -| `gofasta g method Order Archive [param:type ...]` | **Modify-aware.** Append a method to an existing service: signature in `app/services/interfaces/_service.go`, stub impl in `app/services/.service.go`. AST-based (no marker comments left behind, doc comments preserved). `--dry-run` for preview. | -| `gofasta g field Order archive_reason:string` | **Modify-aware.** Add a column to an existing model + DTOs + a paired migration. Patches the model struct, every DTO variant (Create / Update / Response — each opt-out via `--no-create` / `--no-update` / `--no-response`), and writes `db/migrations/NNNNNN_add__to_.{up,down}.sql`. `--dry-run` for preview. | -| `gofasta g endpoint Order POST /orders/{id}/archive` | **Modify-aware.** Add one REST endpoint: handler on the existing controller, route registration, service-interface method (skip with `--no-service`). Handler name auto-derived from ` ` or pass `--handler=`. | -| `gofasta g middleware POST /orders/{id}/archive auth.RequireRole("admin")` | **Modify-aware.** Wrap an existing route with a chi middleware — `r.Post(...)` becomes `r.With().Post(...)`. Idempotent: re-running with a middleware already in the chain is a no-op. | -| `gofasta g repo-method Order FindByCustomer customerID:string` | **Modify-aware.** Repository-layer twin of `g method` — patches `RepositoryInterface` + the repo impl. | -| `gofasta g relation Order belongs_to Customer` | **Modify-aware.** Wire a GORM association on the parent model + emit FK migration (for `belongs_to`). `has_many` / `has_one` add navigation fields without a parent-side migration. | -| `gofasta g rename Order.Total AmountCents` | **Modify-aware.** Cross-file rename of one field: model + DTOs + service + tests + a rename migration. **Preview by default** — pass `--apply` to actually write. Substitution is token-aware (`\bOldField\b`) so partial matches inside larger identifiers are safe. | -| `gofasta g mock OrderService` | Generate (or refresh) a testify/mock implementation under `testutil/mocks/`. `--all` walks both `app/services/interfaces/` and `app/repositories/interfaces/`; `--check` exits non-zero with `MOCK_DRIFT` if the on-disk mock no longer matches the interface (CI gate). | -| `gofasta wire` | Regenerate `app/di/wire_gen.go` from Wire's sources | -| `gofasta swagger` | Regenerate OpenAPI docs from code annotations | -| `gofasta routes` | Print every registered REST route (static grep of route files) | -| `gofasta config schema` | Emit the JSON Schema for `config.yaml` — feed to a YAML language server or validate edits before writing | - -Supported field types: `string`, `text`, `int`, `float`, `bool`, `uuid`, `time`. - -### Modifying an existing resource — the modify-aware generator family - -When a resource already exists and you only need to add one method, one -field, or one endpoint, use the modify-aware generator family rather -than running `g scaffold` (which refuses to overwrite existing files) -or hand-editing 4–6 files in lockstep. - -| When you want to … | Use | -|---|---| -| Add a service method | `gofasta g method [param:type ...]` | -| Add a model column (+ DTOs + migration) | `gofasta g field :` | -| Add a REST endpoint to an existing controller | `gofasta g endpoint ` | -| Attach a middleware to an existing route | `gofasta g middleware ` | -| Add a repository method | `gofasta g repo-method ` | -| Wire a GORM association | `gofasta g relation belongs_to|has_many|has_one ` | -| Rename a field across every layer | `gofasta g rename . ` (preview), then `--apply` | -| Refresh test doubles after an interface change | `gofasta g mock ` or `--all` | - -Every modify-aware generator honors `--dry-run --json` and emits the -same `[]PlannedAction` shape `g scaffold --dry-run --json` does — agents -can preview the full diff before applying.

The single "am I done?" check. | -| `gofasta verify --since=` | Change-scoped gauntlet — fmt / vet / lint / test / build run only against files touched since ``. Wire drift + routes stay whole-project. | -| `gofasta status` | Offline drift report — stale Wire, stale Swagger, pending migrations, uncommitted generated files, `go.sum` freshness. | -| `gofasta inspect ` | AST-parsed structured report of a resource's model, DTOs, service methods, controller methods, and routes. | -| `gofasta inspect-jobs []` | Static AST scan of `app/jobs/*.go` — every registered job, its Go type, and its cron schedule from `config.yaml`. | -| `gofasta inspect-tasks []` | Static AST scan of `app/tasks/*.task.go` — every `Task` constant plus its payload struct + Handle / Enqueue presence flags. | -| `gofasta migrate up --explain` | Static SQL analysis of every pending `.up.sql` — flags lock-impact, data-loss, and app-incompatibility patterns before they hit the DB. `--strict` exits non-zero on high-severity warnings (CI gate). | -| `gofasta debug stack` | Resolve captured stack frames (`TraceSpan.Stack` / `ExceptionEntry.Stack`) to source-context windows. Three input modes: `--trace=`, `--last-error`, or `-` (stdin). | -| `gofasta debug replay ` | SSRF-safe re-fire of a captured request by ID. `--method`, `--path`, `--header=K:V`, `--body=@file` overrides; `--strip-auth` to drop Authorization+Cookie. The upstream URL is pinned by the skeleton's `/debug/replay` handler — overrides can change path/headers/body but never scheme/host/port. | -| `gofasta xrefs ` | Type-aware reverse lookup — every file:line:col reference to a Go symbol across the module. Uses `golang.org/x/tools/go/packages`, so survives renames, aliasing, and method-set resolution. | -| `gofasta impact ` | Reverse-dependency analysis at the package level. Direct + transitive importers + every impacted source file. Pipe the file list into `gofasta verify --since=` for a maximally-scoped CI gate. | -| `gofasta debug <...>` | Query a running dev app's `/debug/*` surface — requests, SQL, traces, logs, errors, goroutines, pprof, HAR. See the dedicated Debug section above for the full command list. | -| `gofasta config schema` | Emit the JSON Schema for `config.yaml`. Validates edits before writing; powers editor autocomplete. | -| `gofasta do ` | Named workflow chains: `new-rest-endpoint`, `rebuild`, `fresh-start`, `clean-slate`, `health-check`. | -| `gofasta do list` | List every registered workflow. | -| `gofasta ai ` | Install per-agent configuration (Claude, Cursor, Codex, Aider, Windsurf). Idempotent. | - -## Conventions the agent must follow - -- **Layered architecture** — honor the Request → Controller → Service → Repository → Database pipeline. A new dependency that skips a layer (e.g., controller calling the repo directly) is a code smell and usually a mistake. -- **Interface at each boundary** — repositories and services expose Go interfaces in their `interfaces/` subdirectory. Higher layers depend on the interface, not the concrete type. This is what makes the layer swappable. -- **DTOs for the API, models for the DB** — never expose a GORM model in a response body or accept one as a request body. Always translate through `app/dtos/`. -- **Error handling** — controllers return `error`. Wrap with `httputil.Handle(...)` from `github.com/gofastadev/gofasta/pkg/httputil` to adapt to `http.HandlerFunc`. Use typed errors from `github.com/gofastadev/gofasta/pkg/errors` (`NewBadRequest`, `NewNotFound`, etc.) so the middleware can map to the right HTTP status. -- **Context propagation** — `ctx context.Context` is the first parameter through every layer. Never call a repository without passing the request context. -- **Validation at the boundary** — `validator:"required,email"` style tags on DTOs; validators run at the controller before the service is called. Services assume input is already validated. -- **Config over constants** — read from `config.yaml` via `pkg/config`, not hardcoded values. Environment variables override with the `{{.ProjectNameUpper}}_` prefix (e.g., `{{.ProjectNameUpper}}_DATABASE_HOST`). -- **Swagger annotations on controller methods** — `@Summary`, `@Tags`, `@Param`, `@Success`, `@Router` comments drive OpenAPI generation. Add them when you add endpoints. - -## Things the agent must NOT do - -1. **Do not edit `app/di/wire_gen.go`.** It's generated. Edit `app/di/wire.go` (or add a new file in `app/di/providers/`), then run `gofasta wire` to regenerate. Commit both. -2. **Do not skip migrations.** If you add a field to a model, write a migration pair in `db/migrations/`. Never rely on `AutoMigrate` in production code. -3. **Do not put GORM tags on DTOs.** DTOs describe the API contract, not the database schema. GORM tags belong on `app/models/*` types only. -4. **Do not reorganize the directory layout** (`controllers/`, `services/`, `repositories/`, etc.). The scaffold's generators assume this layered shape. If the team wants feature-module layout, that's a dedicated migration — see the project-structure docs. -5. **Do not add business logic to controllers.** Parse the request, call the service, format the response. Nothing else. -6. **Do not call the database from a service.** Call the repository interface. The service depends on the abstraction, not the implementation. -7. **Do not commit generated files that aren't already committed** (e.g., don't add `docs/swagger.json` if it's already being regenerated by CI). Check `.gitignore` first. -8. **Do not swap or remove `pkg/*` imports speculatively.** Each `pkg/*` is an opt-out default; if replacing it is part of the actual task, do it. If not, leave it alone — the user chose these defaults for a reason. - -## Wire gotcha (the most common agent failure mode) - -Google Wire is compile-time DI. The flow is: - -1. Add a new service/controller struct. -2. Add a `New` constructor. -3. Add the constructor to a provider set in `app/di/providers/`. -4. Add the provider set to `app/di/wire.go`. -5. Add the field to `app/di/container.go`. -6. **Run `gofasta wire`** to regenerate `app/di/wire_gen.go`. -7. Update `cmd/serve.go` to pass the new controller into `routes.RouteConfig`. - -If you forget step 6, `go build` will fail with "undefined: someProvider". If -you forget step 7, the route handler panics at startup. Always run -`gofasta wire` after adding a provider. `gofasta g scaffold` automates all -seven steps; prefer the generator over manual wiring. - -## Feature flags - -`pkg/featureflag` wraps the OpenFeature Go SDK. The scaffold does not -register a provider by default — flag evaluations resolve to the -caller-supplied default. To opt in, call `openfeature.SetProvider(...)` at -startup with any OpenFeature-compatible provider (in-memory for dev, -Flagd, LaunchDarkly, go-feature-flag, or custom). See -`configs/features.yaml` for notes. - -## Where to read more - -### Preferred entry points - -Two LLM-optimized files expose the entire gofasta documentation in the -format agents consume most efficiently. Prefer these over scraping -individual pages, and use them **instead of** training-data recall -(which may be stale — features change between releases). - -- **https://gofasta.dev/llms.txt** — structured markdown index of every - docs page with a one-line description and URL, following the - [llmstxt.org](https://llmstxt.org) spec. ~11 KB. Use this to discover - which page answers a specific question, then fetch just that page. -- **https://gofasta.dev/llms-full.txt** — the entire docs site - concatenated into a single markdown file (~440 KB / ~110k tokens). - Use this when you want all gofasta context loaded at once and can - afford the token cost — every API signature, every CLI flag, every - design rationale in one fetch. - -Rule of thumb: if you're answering a specific question about gofasta, -fetch `llms.txt`, pick the right page URL from the index, then fetch -that single page.

-```bash -gofasta verify --json # full quality-gate gauntlet -gofasta status --json # drift detection -``` - -Or in one call: - -```bash -gofasta do health-check --json -``` - -If anything fails, the JSON output tells you precisely which check -broke and what the remediation is (via the `hint` and `docs` fields). - -The detailed checklist, for reference: - -- [ ] `gofasta verify` passes (covers build, tests, lint, fmt, vet, Wire drift, routes) -- [ ] `gofasta status` reports no drift (Wire, Swagger, migrations, generated files) -- [ ] `gofasta routes --json` shows any new endpoints you added -- [ ] If you added a Wire provider: `gofasta wire` was run and `wire_gen.go` is up to date -- [ ] If you added a model field: a migration exists in `db/migrations/` -- [ ] If you added a controller endpoint: Swagger annotations are present -- [ ] If you edited `config.yaml`: it validates against `gofasta config schema` -- [ ] No edits to `app/di/wire_gen.go` - -If any item fails, fix it before reporting the task complete.

of opening six files. - **`gofasta config schema`** — emits a Draft-7 JSON Schema describing `config.yaml`. Shells out to the project-local `cmd/schema/` helper so the schema always matches the `gofasta` version pinned in the project's `go.mod`.

Agents pattern-match on the code instead of regex-parsing English. - **Global `--json` flag** — every structured-output command honors it, producing a single-line JSON document for agent consumption. - **Post-generation auto-verify** — `gofasta g scaffold` automatically runs `go build ./...` after generation so template regressions surface immediately. Disable with `--no-verify`. - **Generator `--dry-run`** — `gofasta g scaffold --dry-run` shows every file it would create and every patch it would apply without touching disk. - **Per-resource controller test scaffolding** — `gofasta g scaffold` now emits a starter `.controller_test.go` with smoke tests + a TODO placeholder, so generated resources are green on `go test` out of the box. -- **`AGENTS.md` in every scaffolded project** — comprehensive agent briefing (project overview, tech stack, every command, conventions, Wire gotcha walkthrough, "do not do" list, pre-commit self-check). Read automatically by Claude Code, OpenAI Codex, Cursor, Aider, and other MCP-aware agents. +- **No scaffold-time agent files** — `gofasta new` ships a project with zero agent-related files at the root.

Check `.gitignore` first. +8. **Do not swap or remove `pkg/*` imports speculatively.** Each `pkg/*` is an opt-out default; if replacing it is part of the actual task, do it.

The shortest, highest-value +chunk — if Claude reads only one rule before starting work, this is it. + +## Conventions the agent must follow + +- **Layered architecture** — honor the Request → Controller → Service → Repository → Database pipeline. A new dependency that skips a layer (e.g., controller calling the repo directly) is a code smell and usually a mistake. +- **Interface at each boundary** — repositories and services expose Go interfaces in their `interfaces/` subdirectory. Higher layers depend on the interface, not the concrete type. This is what makes the layer swappable. +- **DTOs for the API, models for the DB** — never expose a GORM model in a response body or accept one as a request body. Always translate through `app/dtos/`. +- **Error handling** — controllers return `error`. Wrap with `httputil.Handle(...)` from `github.com/gofastadev/gofasta/pkg/httputil` to adapt to `http.HandlerFunc`. Use typed errors from `github.com/gofastadev/gofasta/pkg/errors` (`NewBadRequest`, `NewNotFound`, etc.) so the middleware can map to the right HTTP status. +- **Context propagation** — `ctx context.Context` is the first parameter through every layer. Never call a repository without passing the request context. +- **Validation at the boundary** — `validator:"required,email"` style tags on DTOs; validators run at the controller before the service is called. Services assume input is already validated. +- **Config over constants** — read from `config.yaml` via `pkg/config`, not hardcoded values. Environment variables override with the `{{.ProjectNameUpper}}_` prefix (e.g., `{{.ProjectNameUpper}}_DATABASE_HOST`). +- **Swagger annotations on controller methods** — `@Summary`, `@Tags`, `@Param`, `@Success`, `@Router` comments drive OpenAPI generation. Add them when you add endpoints. + +## Things the agent must NOT do + +1. **Do not edit `app/di/wire_gen.go`.** It's generated. Edit `app/di/wire.go` (or add a new file in `app/di/providers/`), then run `gofasta wire` to regenerate. Commit both. +2. **Do not skip migrations.** If you add a field to a model, write a migration pair in `db/migrations/`. Never rely on `AutoMigrate` in production code. +3. **Do not put GORM tags on DTOs.** DTOs describe the API contract, not the database schema. GORM tags belong on `app/models/*` types only. +4. **Do not reorganize the directory layout** (`controllers/`, `services/`, `repositories/`, etc.). The scaffold's generators assume this layered shape. If the team wants feature-module layout, that's a dedicated migration — see the project-structure docs. +5. **Do not add business logic to controllers.** Parse the request, call the service, format the response. Nothing else. +6. **Do not call the database from a service.** Call the repository interface. The service depends on the abstraction, not the implementation. +7. **Do not commit generated files that aren't already committed** (e.g., don't add `docs/swagger.json` if it's already being regenerated by CI). Check `.gitignore` first. +8. **Do not swap or remove `pkg/*` imports speculatively.** Each `pkg/*` is an opt-out default; if replacing it is part of the actual task, do it. If not, leave it alone — the user chose these defaults for a reason. + +## Wire gotcha (the most common agent failure mode) + +Google Wire is compile-time DI. The flow is: + +1. Add a new service/controller struct. +2. Add a `New` constructor. +3. Add the constructor to a provider set in `app/di/providers/`. +4. Add the provider set to `app/di/wire.go`. +5. Add the field to `app/di/container.go`. +6. **Run `gofasta wire`** to regenerate `app/di/wire_gen.go`. +7. Update `cmd/serve.go` to pass the new controller into `routes.RouteConfig`. + +If you forget step 6, `go build` will fail with "undefined: someProvider". If +you forget step 7, the route handler panics at startup. Always run +`gofasta wire` after adding a provider. `gofasta g scaffold` automates all +seven steps; prefer the generator over manual wiring. + +## Feature flags + +`pkg/featureflag` wraps the OpenFeature Go SDK. The scaffold does not +register a provider by default — flag evaluations resolve to the +caller-supplied default. To opt in, call `openfeature.SetProvider(...)` at +startup with any OpenFeature-compatible provider (in-memory for dev, +Flagd, LaunchDarkly, go-feature-flag, or custom).

The scaffold's generators assume this layered shape.

Check `.gitignore` first. +8. **Do not swap or remove `pkg/*` imports speculatively.** Each `pkg/*` is an opt-out default; if replacing it is part of the actual task, do it.

Never rely on `AutoMigrate` in production code. +3. **Do not put GORM tags on DTOs.** DTOs describe the API contract, not the database schema. GORM tags belong on `app/models/*` types only. +4. **Do not reorganize the directory layout** (`controllers/`, `services/`, `repositories/`, etc.). The scaffold's generators assume this layered shape. +5. **Do not add business logic to controllers.** Parse the request, call the service, format the response.

A new dependency that skips a layer (e.g., controller calling the repo directly) is a code smell and usually a mistake. +- **Interface at each boundary** — repositories and services expose Go interfaces in their `interfaces/` subdirectory. Higher layers depend on the interface, not the concrete type. This is what makes the layer swappable. +- **DTOs for the API, models for the DB** — never expose a GORM model in a response body or accept one as a request body. Always translate through `app/dtos/`. +- **Error handling** — controllers return `error`. Wrap with `httputil.Handle(...)` from `github.com/gofastadev/gofasta/pkg/httputil` to adapt to `http.HandlerFunc`. Use typed errors from `github.com/gofastadev/gofasta/pkg/errors` (`NewBadRequest`, `NewNotFound`, etc.) so the middleware can map to the right HTTP status. +- **Context propagation** — `ctx context.Context` is the first parameter through every layer. Never call a repository without passing the request context. +- **Validation at the boundary** — `validator:"required,email"` style tags on DTOs; validators run at the controller before the service is called. Services assume input is already validated. +- **Config over constants** — read from `config.yaml` via `pkg/config`, not hardcoded values. Environment variables override with the `{{.ProjectNameUpper}}_` prefix (e.g., `{{.ProjectNameUpper}}_DATABASE_HOST`). +- **Swagger annotations on controller methods** — `@Summary`, `@Tags`, `@Param`, `@Success`, `@Router` comments drive OpenAPI generation. Add them when you add endpoints. + +## Things the agent must NOT do + +1. **Do not edit `app/di/wire_gen.go`.** It's generated. Edit `app/di/wire.go` (or add a new file in `app/di/providers/`), then run `gofasta wire` to regenerate. Commit both. +2. **Do not skip migrations.** If you add a field to a model, write a migration pair in `db/migrations/`. Never rely on `AutoMigrate` in production code. +3. **Do not put GORM tags on DTOs.** DTOs describe the API contract, not the database schema. GORM tags belong on `app/models/*` types only. +4. **Do not reorganize the directory layout** (`controllers/`, `services/`, `repositories/`, etc.). The scaffold's generators assume this layered shape. If the team wants feature-module layout, that's a dedicated migration — see the project-structure docs. +5. **Do not add business logic to controllers.** Parse the request, call the service, format the response. Nothing else. +6. **Do not call the database from a service.** Call the repository interface. The service depends on the abstraction, not the implementation. +7. **Do not commit generated files that aren't already committed** (e.g., don't add `docs/swagger.json` if it's already being regenerated by CI). Check `.gitignore` first. +8. **Do not swap or remove `pkg/*` imports speculatively.** Each `pkg/*` is an opt-out default; if replacing it is part of the actual task, do it. If not, leave it alone — the user chose these defaults for a reason. + +## Wire gotcha (the most common agent failure mode) + +Google Wire is compile-time DI. The flow is: + +1. Add a new service/controller struct. +2. Add a `New` constructor. +3. Add the constructor to a provider set in `app/di/providers/`. +4. Add the provider set to `app/di/wire.go`. +5. Add the field to `app/di/container.go`. +6. **Run `gofasta wire`** to regenerate `app/di/wire_gen.go`. +7. Update `cmd/serve.go` to pass the new controller into `routes.RouteConfig`. + +If you forget step 6, `go build` will fail with "undefined: someProvider". If +you forget step 7, the route handler panics at startup. Always run +`gofasta wire` after adding a provider. `gofasta g scaffold` automates all +seven steps; prefer the generator over manual wiring. + +## Feature flags + +`pkg/featureflag` wraps the OpenFeature Go SDK. The scaffold does not +register a provider by default — flag evaluations resolve to the +caller-supplied default. To opt in, call `openfeature.SetProvider(...)` at +startup with any OpenFeature-compatible provider (in-memory for dev, +Flagd, LaunchDarkly, go-feature-flag, or custom).

Parse with `jq`, `json.Unmarshal`, etc. + + ```bash + gofasta routes --json | jq '.[] | select(.method == "POST") | .path' + gofasta verify --json | jq '.checks[] | select(.status == "fail")' + gofasta inspect User --json | jq '.service_methods[].name' + gofasta status --json | jq '.checks[] | select(.status == "drift")' + gofasta g scaffold Invoice total:float --dry-run --json | jq '.planned_files' + ``` + +2. **NDJSON (newline-delimited).** One JSON object per line, emitted as + events happen. `gofasta dev --json` is the main example — emits + `preflight`, `service`, `migrate`, `air`, and `shutdown` events: + + ```bash + gofasta dev --json | jq -c 'select(.event=="service" and .status=="unhealthy")' + gofasta dev --json | jq -c 'select(.event=="air" and .status=="running")' | head -1 + ``` + +**Exit codes.** `--json` does NOT suppress exit codes. A failing +command still exits non-zero; the JSON on stderr tells you why. Always +branch on the exit code first, then read the error payload: + +```bash +if ! gofasta verify --json > result.json 2> error.json; then + jq -r '.code' error.json # e.g. "GO_TEST_FAILED" + jq -r '.hint' error.json # remediation in one line + exit 1 +fi +``` + +**Stream separation.** Success output goes to **stdout**; errors go to +**stderr**. Never mix them. + +**Error shape.** Every error in `--json` mode serializes as: + +```json +{ + "code": "WIRE_MISSING_PROVIDER", + "message": "undefined: NewOrderProvider", + "hint": "add NewOrderProvider to app/di/providers/order.go and run `gofasta wire`", + "docs": "https://gofasta.dev/docs/cli-reference/wire" +} +``` + +Pattern-match on `code` (stable API, never renamed). The `hint` is the +exact remediation. The `docs` URL is the most relevant reference. + +## Parse error codes, not error text + +Codes are grouped by subsystem — `WIRE_*`, `HEALTH_*`, `DEV_*`, +`DEPLOY_*`, `SEED_*`, `ROUTES_*`, `INIT_*` — and are never renamed once +shipped. + +## Understand a resource before modifying it + +When asked to change an existing resource (e.g. "add a `SoftArchive` +method to `Order`"), **run `gofasta inspect ` first**. It +AST-parses the model, DTOs, service interface, controller methods, and +routes, emitting the whole resource shape as one structured document. + +```bash +gofasta inspect Order --json +``` + +Reveals every field in the model, every DTO type, every service- +interface method signature, every controller method signature, every +registered route — in one call, in a shape that parses cleanly. +Replaces opening six files and guessing. + +## Check for drift before making changes + +`gofasta status` is the offline "is this project in a clean state?" +check. Reports when derived artifacts (Wire, Swagger) are out of sync +with their inputs, when migrations are pending, and when regenerated +files show up as uncommitted in git. Run it when entering the project +cold — if anything reports `drift`, fix it before starting work. + +```bash +gofasta status # one-glance drift report +gofasta status --json # structured consumption +``` + +## Use workflows to avoid multi-round-trip command chains + +When a task requires multiple gofasta commands in sequence, use +`gofasta do ` instead of invoking each command separately. +Fewer tool calls, stable atomic contract, transparent step list. + +```bash +gofasta do list # every workflow +gofasta do new-rest-endpoint Invoice total:float # scaffold + migrate up + swagger +gofasta do rebuild # wire + swagger +gofasta do clean-slate # db reset + seed +gofasta do health-check # verify + status +``` + +Pass `--dry-run` to preview without executing. Use `--json` for a +structured `{workflow, steps[], status, duration_ms}` result. + +## Validate config edits against the schema + +When editing `config.yaml`, generate the schema first to know what keys +and values are valid — don't guess from memory: + +```bash +gofasta config schema > /tmp/config.schema.json +ajv validate -s /tmp/config.schema.json -d config.yaml +``` + +The schema is emitted by a project-local helper (`./cmd/schema`) so it +always matches the exact `gofasta` version pinned in `go.mod`. + +## Use the right generator, not hand-written CRUD + +Before writing any CRUD code by hand, check whether a `gofasta g *` +generator produces the right starting point. See the commands rule +(`commands.md`) for the full generator catalog. The scaffold auto-wires +every layer and runs `go build ./...` after generation to catch +template regressions immediately. + +If unsure what a generator would produce, run it with `--dry-run` — +every file it would create and every patch it would apply is printed +without touching disk. + +```bash +gofasta g scaffold Invoice total:float --dry-run +``` + +## One command to verify your work + +The single most important command for agents: **`gofasta verify`**. +Runs gofmt, `go vet`, `golangci-lint`, `go test -race`, `go build`, +Wire drift check, and routes sanity — in one invocation. Run it +**before** claiming any task is done. `--json` output gives per-check +status so you can pinpoint failures: + +```bash +gofasta verify --json | jq '.checks[] | select(.status == "fail")' +``` + +Wrap in `gofasta do health-check` to also run `gofasta status` (drift +detection) at the same time. + +See `debugging.md` for the `gofasta debug` family that turns failing +requests into structured JSON instead of grep-through-logs sessions.
