Tests whose assertion is recomputed the way the code computes it pass by construction and give zero confidence. Add it as a peer of the existing implementation-coupling anti-pattern: a Philosophy principle, a per-cycle checklist gate, and a BAD/GOOD example pair in tests.md. Includes a patch changeset.

Engineering
Skills I use daily for code work.
User-invoked
Reachable only when you type them (disable-model-invocation: true).
- ask-matt — Ask which skill or flow fits your situation. A router over the user-invoked skills in this repo.
- grill-with-docs — Grilling session that also builds your project's domain model, sharpening terminology and updating
CONTEXT.mdand ADRs inline. - triage — Move issues through a state machine of triage roles.
- improve-codebase-architecture — Scan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick.
- setup-matt-pocock-skills — Configure this repo for the engineering skills (issue tracker, triage labels, domain doc layout). Run once per repo.
- to-issues — Break any plan, spec, or PRD into independently-grabbable issues using vertical slices.
- to-prd — Turn the current conversation into a PRD and publish it to the issue tracker.
Model-invoked
Model- or user-reachable (rich trigger phrasing so the model can reach for them).
-
prototype — Build a throwaway prototype to answer a design question: a runnable terminal app for state/logic, or several toggleable UI variations.
-
diagnosing-bugs — Disciplined diagnosis loop for hard bugs and performance regressions: reproduce → minimise → hypothesise → instrument → fix → regression-test.
-
tdd — Test-driven development with a red-green-refactor loop. Builds features or fixes bugs one vertical slice at a time.
-
domain-modeling — Actively build and sharpen a project's domain model — challenge terms, stress-test with scenarios, update
CONTEXT.mdand ADRs inline. -
codebase-design — Shared discipline and vocabulary for designing deep modules: small interfaces, clean seams, testable through the interface.
