Run `mise run license` to apply. -- Every package has a `doc.go` with a package-level doc comment. -- Every exported Go declaration (functions, methods, types, constants, variables) must have a Go doc comment that starts with the declaration name. -- Doc comments must be directly attached to the declaration they document (no blank line between comment and declaration). -- Keep comments directly attached to the code they describe (avoid empty lines between a comment block and the following statement/declaration). -- Sentinel errors live in `errors.go` within each package. Use `errCamelCase` naming. -- No `testify` or assertion libraries — tests use stdlib `testing` only. -- Prefer visual separation between logic blocks: - - Add an empty line before `return`, non-error-guard `if`, and `for` when they are not the first statement in their current block. - - Do not add a blank line before those statements when they are the first statement in the current block (`func`, `if`/`else`, `for`, `switch`/`case`, or nested block). - - Keep adjacent logical blocks separated by one blank line, except tightly coupled `switch`/`case` style flows. - - Add an empty line between setup assignments and the first decision branch when it improves scanability. - -### HCL <-> YAML conversion - -- **Parse** = HCL to YAML (the "forward" direction). -- **Unparse** = YAML to HCL (the "reverse" direction). -- `$${{ }}` in HCL string literals becomes `${{ }}` in YAML (double-dollar escaping). -- Document type is auto-detected during unparse: workflow (has `on`+`jobs`), action (has `name`+`runs`, no `on`/`jobs`), or step-only fallback. -- Actions write to `//action.yml`. Workflows write to `/.yaml`. -- All `runs.using` types (composite, node20, docker) work in both directions. Only composite needs special handling for `steps` reference resolution; all other attributes flow through generic parsing. - -### Schema contracts (critical) - -- Provider parse schema must be defined by typed HCL structs in `provider//config.go` (HCL tags are the source of truth). -- Avoid ad-hoc "allowed attribute/key" maps for schema enforcement. They drift from parser contracts and create duplicate maintenance. -- `hcl:",remain"` is allowed only for intentional pass-through islands (for example deeply nested free-form sections), not as the default parse strategy. -- For unparse YAML validation, prefer strict typed decode (`goccy/go-yaml` strict mode) over hand-maintained key allowlists. -- Decoder-native diagnostics are acceptable and preferred. Tests should assert stable substrings from strict decoder errors instead of custom-normalized wording. -- When adding fields, update typed structs first, then conversion logic, then fixtures/tests. Never add schema keys in validation-only tables. - -### YAML output - -- Uses `gopkg.in/yaml.v3` node-level marshalling for precise control. -- Strings that need quoting use `DoubleQuotedStyle` (not single quotes — Zed editor converts `'` to `"` on save, breaking golden tests). -- `stringNeedsQuoting()` determines when to quote: empty strings, booleans, null, numbers, YAML special characters. The `@` character does NOT trigger quoting (e.g., `actions/checkout@v4` stays unquoted). -- Top-level key order: `name`, `run-name`, `on`, `jobs`, then remaining keys alphabetically. -- Uses `goccy/go-yaml` for test assertions (semantic comparison), but `gopkg.in/yaml.v3` for production marshalling. - -### Testing - -- **Golden tests**: compare generated output against `.golden.yaml` files. Use `assertYAMLSemanticEqual` (not byte comparison). -- **Roundtrip tests**: HCL -> YAML -> HCL -> YAML, assert semantic equality. Proves bidirectional stability. -- **Fixture matrix**: structured under `testdata/fixtures/matrix/{parse,unparse}/{valid,invalid}/`. Valid cases have `.hcl`+`.golden.yaml`, invalid cases have `.hcl`+`.error.txt`. -- **Action fixtures**: under `testdata/fixtures/actions/` — composite, node, docker action types. -- **Benchmark tests**: `BenchmarkParseWorkflow`, `BenchmarkUnparseWorkflow`, `BenchmarkRoundtripWorkflow`. - -### Commits - -- Conventional commits enforced via `commitlint` (types: feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert). -- Header max 50 chars, body/footer max 72 chars per line. -- Changelog managed by `git-cliff`. - -### CI/CD - -- GitHub Actions workflows in `.github/workflows/`. -- `mise run test` runs the key test suites before release. - -## Adding a new provider - -1. Create `provider//` implementing `provider.Provider`. -2. Wire it into `cinzel.go` alongside `github.New()`. -3. Add `provider//README.md` with HCL schema reference. -4.

Action version pinning (`cinzel pin`) + +The LLM outputs tag-based versions (`actions/checkout@v4`) because it doesn't know current SHAs. cinzel resolves them via GitHub API: + +``` +1.

This is non-destructive — running `assist` multiple times overwrites only the `assist/` folder. + +## Resolved questions + +1. **Context injection** — Yes. `assist` reads existing `./cinzel/*.hcl` files and includes them in the LLM prompt. This lets the LLM reference existing steps (e.g., `step.checkout`, `step.mise_setup`) instead of duplicating them, and avoids conflicting workflow/job names. + +2. **Validation feedback loop** — Yes. If unparse fails, cinzel feeds the error back to the LLM for a retry. Cap at 2 retries to avoid runaway costs. Flow: generate → unparse → fail → retry with error context → unparse → succeed or abort. + +3. **Multiple files** — Optimize LLM calls. If the prompt implies multiple workflows, generate them in a single LLM call (the YAML can contain multiple documents separated by `---`). Only split into separate calls if the single-call output fails validation. + +## Resolved: remaining questions + +4. **Refinement flow** — Both `--prompt` and `--refine` supported: + ```sh + cinzel github assist --prompt "golang PR with tests" # fresh generation + cinzel github assist --refine "add slack on failure" # iterates on previous + ``` + `--prompt` starts fresh (injects existing `./cinzel/*.hcl` as context). + `--refine` builds on previous output (injects both `./cinzel/*.hcl` AND `./cinzel/assist/*.hcl` as context). The LLM sees the full picture and modifies accordingly. `--refine` without a previous `assist/` output errors with "nothing to refine". + +5. **Cost transparency** — First run shows a confirmation: "This will call {provider} ({model}). API usage will incur costs. Continue? [y/N]". The `--acknowledge` flag bypasses this confirmation for CI or scripted use: + ```sh + cinzel github assist --prompt "..." --acknowledge + ``` + +6. **Streaming** — No streaming.

Shared steps appear once. + +3. **System prompt for step reuse** — instructs the LLM to use identical step names/IDs across workflows so dedup works. + +4. **Top-level vs nested** — `assist` is top-level (provider-agnostic, takes `--provider` flag). `pin` and `upgrade` are under `cinzel github` (GitHub-specific operations). + +## Privacy: string literal stripping + +Instead of a redaction/restoration engine, `StripHCLContext` walks the HCL AST and replaces ALL string literal values with `"..."`. Comments are dropped by the parser. Block labels preserved (accepted residual risk — comparable to function names). + +The LLM sees structural skeleton only: +```hcl +step "checkout" { + name = "..." + uses { + action = "..." + version = "..." + } +} +``` + +Context capped at 8000 tokens with newline-boundary truncation. + +## Pin: tag-to-SHA resolution + +`Resolver` interface with `GitHubResolver` (GitHub API) and `CachedResolver` (file-based, 24h TTL in `os.UserCacheDir()/cinzel/pins/`). + +- Handles annotated tags (dereferences to commit SHA) +- Adds/updates `// actions/checkout v4` comment above `uses` blocks +- Fallback on failure: warning + keep unpinned tag +- `GITHUB_TOKEN` env var for authenticated requests (5000/hr vs 60/hr) + +## Upgrade: latest version lookup + +Uses GitHub releases API (`/repos/.../releases/latest`). Compares by tag OR SHA — detects already-current versions even when SHA-pinned. No cache (must check live). Optional `--parse` regenerates YAML after upgrading. + +## AI provider interface + +```go +type Provider interface { + Generate(ctx context.Context, req GenerateRequest) (GenerateResponse, error) + Name() string +} +``` + +Two implementations: `Anthropic` and `OpenAI`. Shared `resolveAPIKey` helper. Error classification distinguishes auth/quota/rate-limit/timeout with actionable messages. + +`GenerateResponse` includes `InputTokens`/`OutputTokens` — displayed after every generation. + +## Configuration (`cinzel init`) + +`cinzel init` creates an interactive config file at `os.UserConfigDir()/cinzel/config.yaml` with `0600` permissions: + +```yaml +ai: + default: anthropic + providers: + anthropic: + model: claude-sonnet-4-5-20250514 + api_key: "sk-ant-..." + openai: + model: gpt-4o + api_key: "sk-..." +``` + +Resolution order (highest wins): CLI flags (`--ai`, `--model`) > env vars (`ANTHROPIC_API_KEY`, `OPENAI_API_KEY`) > config file > hardcoded defaults. + +`LoadConfig()` in `internal/ai/config.go` reads the file silently — missing file returns empty config, no error. + +## Review findings addressed + +Three rounds of parallel reviews (architecture, security, simplicity, performance, pattern recognition) produced these fixes: + +| Finding | Fix | +|---------|-----| +| Brace-counting HCL splitter fragile | Replaced with `hclwrite.ParseConfig` AST | +| Regex compiled per call | Hoisted to package-level `var` | +| Sentinel errors scattered | Consolidated into
