Governance Fitness Function Check

Run the requested governance check category. Default to all if no argument provided.

Scope and When to Use

This is a QUICK checklist tool — single-category, fast pass/fail, actionable remediation. Use for:

• Pre-commit spot checks on staged changes
• Quick validation before pushing
• Verifying a specific category (secrets, file size, etc.)

For deep multi-file review with severity grading and domain invariant analysis, use the governance-reviewer agent instead.

Consequence classification: If the task involves irreversible operations (production deploy, data migration, credential rotation), classify as In-the-Loop regardless of task type. [DSGAI19]

Project Type Detection

Before running checks, detect the project's primary language:

If multiple indicators exist, check all relevant languages. If none match, apply generic checks.

Check Categories

pre-commit

Scan staged/changed files for:

1. Hardcoded secrets — Search for patterns: API_KEY=, password=, sk-, sk-ant-, ghp_, AKIA, hardcoded token strings, -----BEGIN PRIVATE KEY-----, JWT tokens (eyJ...), Google API keys (AIza...), Azure connection strings, MongoDB URIs. PII patterns (email, SSN, credit card) generate warnings [DSGAI01]. Use git diff --cached or git diff to get changed content.
2. Input validation — New API endpoints/route handlers MUST have input validation. Check for language-appropriate validation:
   • JS/TS: Zod, joi, yup, express-validator
   • Python: pydantic, marshmallow, cerberus
   • Go: go-validator, custom validation functions
   • Rust: serde with validation, validator crate
3. Parameterized queries — Database queries must use parameterized queries, not string interpolation. Search for SQL string concatenation patterns.
4. File size — No file should exceed 800 lines. Use wc -l on changed files.
5. Function length — No function should exceed 50 lines. Use Grep to find function definitions and count lines.
6. Immutability — Check for direct mutation patterns (.push(, obj.prop = on shared state, delete obj.prop).
7. Debug prints — No debug prints in production code (allow in test files):
   • JS/TS: console.log
   • Python: print( (excluding logging)
   • Go: fmt.Println (excluding structured logging)
   • Rust: println!
8. Dangerous functions — Flag usage of:
   • JS/TS: eval(), innerHTML
   • Python: eval(), exec(), pickle.loads()
   • Go: unsafe.Pointer
   • Rust: unsafe blocks
9. Agent credentials — Check for hardcoded OAuth tokens, bearer tokens, refresh tokens, client secrets in code and config files. Patterns: Bearer , oauth_token=, refresh_token=, client_secret=, Authorization: Bearer. Reference: [DSGAI02].
10. AI model artifacts — Flag committed model files (.onnx, .safetensors, .gguf, .pt, .pkl, .bin >10MB). These should be tracked via Git LFS or external artifact registry, not committed directly. [DSGAI04]
11. Unsafe deserialization — Flag torch.load(), pickle.load(), pickle.loads(), yaml.unsafe_load(), joblib.load() without safe alternatives (weights_only=True, safetensors). [DSGAI04]
12. AI dependency pinning — In requirements.txt/pyproject.toml, flag unpinned AI packages (torch, transformers, openai, anthropic, langchain) using >= or no version pin. [DSGAI04]
13. Telemetry hygiene — Flag patterns logging full prompts/contexts in production: log.*prompt, log.*context, logger.*user_input, console.log.*messages, logging.*completion. Allow in test/debug files. [DSGAI14]
14. Telemetry redaction — If observability configs exist (OpenTelemetry, Datadog, Sentry), verify PII/prompt scrubbing is configured. [DSGAI14]

pre-pr

Check the full branch diff against base:

1. Conventional commits — All commits on this branch must follow format: type: description where type is one of: feat, fix, refactor, docs, test, chore, perf, ci. Use git log --oneline.
2. DOMAIN.md — If entity schemas changed (new fields, new entities, changed types), DOMAIN.md must be updated.
3. Breaking changes — API contract changes (removed fields, changed types, removed endpoints) must be documented in an ADR.
4. Test coverage — Changed files should have corresponding test files. Check for test file existence.
5. TODO context — All TODO comments must include context about what needs to be done and why.

architecture

Periodic architecture review:

1. Service boundaries — No direct cross-service database access. Services communicate through APIs.
2. Error message safety — Error responses must not leak stack traces, internal paths, or sensitive data.
3. Authentication — All non-health-check endpoints require authentication.
4. Rate limiting — Public endpoints should have rate limiting configured.
5. Cache consistency — Cache TTL policies are documented and consistent.
6. Plugin/MCP security — If the project uses Claude Code plugins or MCP servers: (a) plugins are from trusted sources, (b) MCP tool permissions follow least-privilege (no "allowed-tools": ["*"]), (c) .mcp.json contains no hardcoded credentials. Check .claude/settings.json and MCP configs. Reference: [DSGAI06].
7. Context minimization — Verify that session-start hooks stay under ~500 tokens, CLAUDE.md does not contain secrets or PII, and rules files do not embed real credentials as examples. Reference: [DSGAI15].
8. Agent credential hygiene — Verify agent .md files and skill frontmatter contain no embedded credentials or API keys. Reference: [DSGAI02].
9. Shadow AI policy — If project has shadow-ai-policy.md, verify approved AI tooling is documented. Flag references to unsanctioned AI tool endpoints in source code or configs. [DSGAI03]
10. Irreversible operation safeguards — Scripts/code performing destructive operations (DROP TABLE, rm -rf, force push, production deploy) must have confirmation gates or dry-run modes. [DSGAI19]
11. Session isolation — Agent memory/state must be scoped per-project and per-user. Cache keys must include user/project/session scope. Flag global state stores without scope qualifiers. [DSGAI11]
12. Multi-tenant data separation — In multi-tenant code, verify tenant ID is included in all database queries, cache keys, and file paths. Flag shared state without tenant scoping. [DSGAI11]

Output Format

Present results as a structured checklist:

## Governance Check: [category]

### Passed
- [x] No hardcoded secrets found
- [x] File sizes within limits

### Failed
- [ ] FAIL: `src/api/handler.ts` — 923 lines (max 800)
- [ ] FAIL: Missing input validation in `POST /api/users`

### Warnings
- [!] `src/utils/helper.ts:45` — TODO without context

### Summary
Passed: X/Y | Failed: Z | Warnings: W

When a check maps to a DSGAI control, include the reference in the output line (e.g., [DSGAI02]). For compliance mapping, see docs/compliance/DSGAI-MAPPING.md [DSGAI08]. Data classification guidance: examples/DATA-CLASSIFICATION.md.example [DSGAI07].

If all checks pass, congratulate the user. If any fail, provide specific file paths, line numbers, and remediation guidance.
