Conciseness

The body is lean and assumes Claude's competence: it never explains what gofmt, vet, or race detection are, and every line is a command, a default, or a conditional rule. It matches anchor 5 — every token earns its place — and exceeds anchor 4, which allows minor trimmable explanations (none are evident).

Actionability

All guidance is copy-paste executable: `gofmt -w .`, `go vet ./...`, `go test -v -race ./path/to/package -run TestSpecificName`, `make test`, plus named Makefile targets. The commands cover the common cases (format, vet, focused test, full suite) per anchor 5; the placeholder package path is an appropriate template, not pseudocode, so it stays above anchor 4.

Workflow Clarity

The 'When changing code' section is a clear numbered sequence (fmt → vet → race tests on edited packages + dependents → conditional Ent regeneration → skip-docs rule) where running vet/tests IS the validation, with explicit conditionals for schema and docs-only changes. It falls short of anchor 5 because there is no error-recovery feedback loop (e.g. what to do when vet or tests fail), though the anti-patterns section partially compensates by forbidding unverified pass claims.

Progressive Disclosure

The skill is under 50 lines with no need for external reference files, and no references/ scripts/ or assets/ bundle exists, so per the simple-skill guidance well-organized sections alone qualify. Sections (Defaults, Quick commands, When changing code, Anti-patterns, Related skills) are cleanly delimited; the only links are one-level-deep cross-references to sibling skills and the repo's AGENTS.md, which are clearly signaled rather than buried.

Specificity

The description lists several concrete actions — "Go fmt, vet, race tests, make test" — each naming a real tool or command, with only minor gaps (e.g. coverage/generate-ent workflows omitted). It falls short of anchor 5 because the actions are telegraphically compressed rather than fully elaborated, but it clearly exceeds anchor 3's '1-2 concrete actions'.

Completeness

Both 'what' (fmt, vet, race tests, make test) and 'when' (an explicit 'Trigger:' clause) are present, satisfying the requirement for explicit trigger guidance. It fits anchor 4 — both present but 'when' could be more explicit (it is a keyword list, not a 'Use when...' sentence) — and is clearly above anchor 3, where 'when' is only weakly implied.

Trigger Term Quality

"Trigger: godev, run tests, go vet" includes natural phrases a user would say ("run tests", "go vet") plus tool keywords (fmt, race tests, make test). It misses common variations like "go test", "run the test suite", or "format the Go code", and "godev" is the skill name rather than natural user language — matching anchor 4's 'good coverage, a few natural terms missing' rather than anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The FlexPrice Go tooling niche with triggers like "go vet" and "race tests" is mostly distinct from other skills. Minor overlap risk exists with generic test-runner skills via the broad phrase "run tests", placing it at anchor 4 rather than anchor 5's 'clear niche with minimal conflict risk'.
