building SKILL.md skillA

building from romiluz13/cc10x is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add romiluz13/cc10x/building@git:20261007.84fdb74

Pins git:20261007.84fdb74 in mdr.lock. Pin the fingerprint instead.

Use when writing production code test-first: the RED-GREEN-REFACTOR cycle, false-RED detection, vertical slicing, scope escalation, test process discipline, and code generation patterns.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Building (Code Generation + TDD)

**Iron Law:** NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST.

## Reference Files

Read only what's needed:

- `references/testing-patterns.md` — test structure, isolation, naming; load when writing the first test of a cycle or a test feels awkward to structure
- `references/test-data-and-mocks.md` — mock discipline, test data factories; load when a test needs fixtures/factories or you are about to mock anything
- `references/integration-and-live-proof.md` — integration test guidance, live verification; load when the slice crosses a service/DB/API boundary or the plan names live proof

## Test Process Discipline

- **Always use run mode:** `CI=true npm test`, `npx vitest run` (NOT `npx vitest`), `CI=true npx jest` — watch mode never exits, so the agent hangs waiting for a prompt that never returns
- **Timeout guard:** `timeout 60s npx vitest run` if uncertain about CI=true
- **After TDD cycle:** `pgrep -f "vitest|jest" || echo "Clean"`. Kill if found — orphaned watchers hold ports and re-run stale code, producing false greens in later cycles.
- **IDE vs CLI truth:** If CLI tests pass with exit 0, trust CLI over IDE/LSP errors (stale cache)

How to install

The exact contents, by fingerprint
mdr add romiluz13/cc10x/building@sha256:cfd081c6e617e7c5

The line at the top of this page pins the label git:20261007.84fdb74, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
