csd-intent

Cross-runtime audit tool for CSD intent specifications. Validates intent.yaml against CSD-INTENT-01 and confirms every claim is attested by at least one test marker across any test runner - pytest, vitest, Playwright, Jest, or anything that uses the standard intent() / @intent() marker shape.

This tool is standalone. It does not run inside your project's test suite; it is invoked separately (CLI, CI step, or pre-commit hook).

Why it exists

pytest-intent, vitest-intent, and playwright-intent provide the test-side marker helpers - they let a test declare which intent claim it attests. They deliberately know nothing about other runtimes, schema validation, or whether a claim is unattested.

csd-intent owns the cross-runtime auditing: it walks every test file in the project (Python via AST, TS/JS via regex), reads intent.yaml, and answers:

1. Schema - does every claim match CSD-INTENT-01?
2. Orphan - does every test marker reference a real claim?
3. Coverage - does every claim have at least one attesting test, anywhere?

Install

# From PyPI:
pip install csd-intent

# Local dev against a csd-library checkout:
pip install -e path/to/csd-library/csd-intent

Use

# Audit the current directory (expects intent.yaml at the root):
csd-intent

# Audit a specific project:
csd-intent /path/to/project

# Audit but tolerate unattested claims (the "intent before test" workflow):
csd-intent --fail-on schema

# Constrain the scan to specific directories:
csd-intent --tests-dir backend/tests --tests-dir frontend/src --tests-dir e2e

# Quiet summary only:
csd-intent --quiet

Exit code is 0 on a clean audit, 1 when any violation falls into the configured --fail-on set (any by default).

Output

intent.yaml (/path/to/project/intent.yaml): 24 claims, 2 violation(s).

UNATTESTED (2):
  [unattested] INT-SB-018: no @intent / intent() marker references this claim
  [unattested] INT-SB-029: no @intent / intent() marker references this claim

What it scans

• Python: any file matching test_*.py or *_test.py, walked via AST for @intent("INT-...") decorators on functions starting with test_.
• JS/TS: any file matching *.test.{ts,tsx,js,jsx,mts,cts} or *.spec.{ts,...}, scanned by regex for intent('INT-...', 'name', fn) calls (single-ID and array-of-IDs forms both supported).
• Excluded directories: node_modules, .venv, venv, dist, build, .git, __pycache__, .pytest_cache, .mypy_cache, .ruff_cache, .tox.

CSD-INTENT-01 conformance

The schema check validates each claim against the canonical fields per CSD-INTENT-01 §4.1:

INT-NNN:
  version: 1.0.0
  status: active                # draft | active | deprecated
  statement: "..."              # >= 10 chars, RFC 2119 language
  rationale: "..."              # optional but recommended
  test:
    scope: integration          # unit | integration | e2e | llm
    component: SwitchFlow
    type: behavior              # invariant | behavior | contract
  criticality: critical         # critical | high | medium | low

For projects still on the legacy flat-scope: shape, the tool accepts it (with no warning) - that's a migration concession, not a recommendation.

Duplicate keys are refused

intent.yaml is parsed with a loader that raises on a repeated key rather than resolving it last-wins. A claim id reused by accident would otherwise delete the earlier claim before any check could see it - and every marker written for that claim would silently start attesting the survivor, with the audit still printing CLEAN. The duplicate is reported as a schema violation naming both lines:

SCHEMA (1):
  [schema] intent.yaml: duplicate key `INT-GATE-006` (first declared on line 42,
  declared again on line 187); YAML would silently keep only the last one

Merge keys still work: <<: *base plus an explicit override is not a duplicate.
