release-test-audit

Testing & Quality

Audit whether the unreleased touchdesigner-mcp diff (since the last tag) is adequately covered by integration tests before a release is cut. Walks every API/MCP surface change in the release range, maps each to the integration suite that should cover it, and reports covered / gap / waived per change. Use before releasing, when checking release test coverage, or when asked whether the release diff "has enough tests". This skill AUDITS coverage across the whole release; it delegates HOW to write or run a test to the `integration-test-guard` skill. Pairs with `prepare-release` and the `release-manager` agent.

Release test audit

Answer one question for a release: is every API/MCP surface change in the unreleased range covered by an integration test? This is a release-wide completeness check — broader than the per-push integration-test-guard hook, which only sees one push at a time and can be legitimately skipped commit by commit. Across a full release those individual skips can add up to a real gap; this audit catches that.

Scope boundary: this skill finds gaps. It does not teach how to write a test — for suite choice, patterns, and run commands, hand off to the integration-test-guard skill.

Step 1 — enumerate the release's surface changes

LAST_TAG=$(git describe --tags --abbrev=0)
git diff "$LAST_TAG"..HEAD --name-only

Keep only files under the API/MCP surface (same paths the guard watches):

src/api/**            OpenAPI schema
src/features/tools/** tool defs + handlers
src/server/**         MCP server
src/tdClient/**       TD HTTP client
src/transport/**      stdio / HTTP transport
td/modules/mcp/**     TD-side Python API

Files outside this set (docs, deps, .claude/**, build config, pure types) need no integration test — list them as N/A so the audit is explicit about what it skipped.

Step 2 — map each change to the suite that must cover it

A surface change in…	Expected suite	Live TD (9981)?
tool response shape / formatting, registration, manifest (`src/features/tools/`, `src/server/`)	`tests/integration/mcpToolsResponse.test.ts`	No (mocked client)
client ↔ WebServer behavior — create/update/delete/exec, TD-side Python (`src/tdClient/`, `td/modules/mcp/`, contract in `src/api/**`)	`tests/integration/touchDesignerClientAndWebServer.test.ts`	Yes
HTTP transport — sessions, `/mcp`, `/health` (`src/transport/**`)	`tests/integration/httpTransport.test.ts`	No (starts HTTP server)

A change spanning two rows needs coverage in each row's suite.

Step 3 — check whether coverage actually exists in the release range

For each surface change, verify a corresponding test was added or updated in the same release range — not just that the suite file exists:

# Did the expected suite change in this release range at all?
git diff "$LAST_TAG"..HEAD --stat -- tests/integration/

# Inspect what changed in the mapped suite, and confirm it exercises THIS change.
git diff "$LAST_TAG"..HEAD -- tests/integration/<mapped-suite>.test.ts

Coverage is real only if the changed suite exercises the changed behavior. A new endpoint with no new/updated assertion in its suite is a gap, even if the suite file was touched for something else. Prefer reconciliation-style tests (compute a value, read it back, compare an invariant) over assertions that pass without the behavior working — flag assertion-only additions as weak coverage.

Step 4 — report the verdict

Emit a table, one row per Step 1 surface change:

Changed file/area	Expected suite	Status	Note
`src/api/paths/api/td/server/exec.yml`	touchDesignerClientAndWebServer	covered	reconciles stdout/stderr readback
`td/modules/mcp/services/node_layout.py`	touchDesignerClientAndWebServer	gap	no test for grid auto-align

Status is one of:

covered — a matching test was added/updated in the range and exercises it.
gap — no matching test, or the suite touched but not for this change.
weak — a test exists but only asserts shape, not behavior (reconcile instead).
waived — genuinely needs no integration test (pure refactor / type-only); state why, matching the SKIP_ITEST_GUARD rationale the guard would accept.

Step 5 — close the gaps (delegate)

For every gap / weak row, hand off to the integration-test-guard skill to pick the suite, write the reconciliation test, and run it. Re-run this audit until every surface change is covered or explicitly waived. Only then is the release ready for prepare-release.

integration-test-guard — how to choose/write/run an integration test (this skill delegates the writing to it).
touchdesigner-self-debug — bring up a real TD + .tox for the live-TD suite.
prepare-release — the release cut that this audit gates.
