Conciseness

The body is largely efficient — command tables, copy-paste code blocks, and terse rules like '`go.sum` MUST be committed — it records cryptographic checksums...'. A few instances could be trimmed: the persona preamble ('You treat every new dependency as a long-term maintenance commitment'), and explanatory asides such as 'AI agents can suggest packages that are unmaintained, low-quality, or unnecessary...' add motivational framing Claude does not need. This fits anchor 4 ('efficient; minor instances of over-explanation') rather than 5, where every token earns its place, but is well above anchor 3's 'unnecessary explanation'.

Actionability

Nearly everything is copy-paste executable: `go get github.com/google/uuid@v1.6.0`, `go get -u=patch ./...`, `go get github.com/google/uuid@none` + `go mod tidy` for removal, a complete `tool` directive workflow (`go get -tool ...`, `go tool ...`, `go install tool`), and a Quick Reference covering the common cases (add, upgrade, tidy, scan, audit, visualize, verify). This matches anchor 5 ('fully executable; copy-paste ready commands; specific examples cover the common cases') and exceeds anchor 4, which permits 'minor gaps'.

Workflow Clarity

The upgrade workflow is clearly sequenced with validation checkpoints: `go get -u=patch ./...` → `go mod tidy` → `go test ./...` → `go vet ./...` → `govulncheck ./...`. The batch-upgrade path is therefore not missing validation, so the cap-at-3 rule does not apply. However, there is no explicit error-recovery feedback loop ('if govulncheck reports findings or tests fail, do X'), which anchor 5 requires ('feedback loops for error recovery'); it fits anchor 4 ('clear sequence with most checkpoints present; minor validation gaps').

Progressive Disclosure

The body is an overview plus quick reference, with six clearly-signaled one-level-deep references in the Deep Dives section ([Versioning & MVS](./references/versioning.md), [Auditing Dependencies](./references/auditing.md), [Dependency Conflicts & Resolution](./references/conflicts.md), [Go Workspaces](./references/workspaces.md), [Automated Dependency Updates](./references/automated-updates.md), [Visualizing the Dependency Graph](./references/visualization.md)) — all six files exist in ./references/ and each entry summarizes its target's scope. A Cross-References section routes to sibling skills. This matches anchor 5 exactly: clear overview, well-signaled one-level references, appropriate split.

Specificity

The description lists many concrete, specific capabilities: 'go.mod and go.sum, `go get` install and upgrade flows, Minimal Version Selection, conflict resolution with replace/exclude/retract, `govulncheck` scanning of the module tree, outdated dependency and binary size auditing, vendoring, `tool` directives, and go.work workspaces' — comprehensive coverage of the domain with no vague filler. It matches the anchor-5 example (multiple specific concrete actions) and is clearly above anchor 4, which allows 'minor gaps in coverage'.

Completeness

It explicitly answers both: WHAT ('Dependency management for Golang projects — go.mod and go.sum, `go get` install and upgrade flows...') and WHEN ('Use when adding, removing, or upgrading Go dependencies, deciding whether to take on a package, resolving version conflicts, or auditing what a module pulls in'), with concrete trigger phrases. It exceeds anchor 4 by also adding explicit do-not-use boundaries ('do NOT use for fixing an exploitable vulnerability... or for wiring Dependabot/Renovate update bots').

Trigger Term Quality

Natural user phrasings are well covered: 'adding, removing, or upgrading Go dependencies', 'resolving version conflicts', 'auditing what a module pulls in', alongside file names (go.mod, go.sum, go.work) and tool names (go get, govulncheck) — the Go equivalent of the 'PDF files, PDFs, .pdf' synonym coverage in the anchor-5 example. It is clearly above anchor 4 ('a few natural terms missing'); a user asking to add, upgrade, or audit a Go dependency would naturally use these terms.

Distinctiveness Conflict Risk

It occupies a clear niche (Go dependency management) with distinct triggers and minimal conflict risk, actively disambiguating from sibling skills via negative boundaries: 'do NOT use for fixing an exploitable vulnerability in code (→ golang-security) or for wiring Dependabot/Renovate update bots into CI workflows (→ golang-continuous-integration)'. This is stronger than anchor 4, which still admits 'minor overlap risk with closely related skills'.
