Conciseness

The body is a dense, command-first reference with almost no explanation of concepts Claude already knows, and the version-sensitive Bun 1.3 linker default is properly quarantined in a 'legacy opt-out' callout rather than scattered. Minor padding remains ('dramatically faster replacement for npm, yarn, and pnpm. Up to **25x faster**') that could be trimmed, so it sits at the 4 anchor rather than 5.

Actionability

Nearly every section is copy-paste-ready: quick-start commands, a flag table, executable JSON/TOML/YAML config snippets, concrete CI YAML, and an error→cause→fix table. The commands cover the common cases (add/remove/update, dev deps, frozen lockfile, workspaces, trustedDependencies), matching the 'fully executable, covers common cases' anchor.

Workflow Clarity

The one real multi-step workflow — lockfile upgrade ('bun install --save-text-lockfile --frozen-lockfile --lockfile-only' then 'rm bun.lockb') — deletes the old lockfile with no verification that the new bun.lock is valid first, and migration steps likewise lack checkpoints. Per the guideline that destructive/batch operations without validation cap workflow clarity at 3, this cannot score higher despite the useful Common Errors feedback table.

Progressive Disclosure

Scored against the actual bundle, only references/cli-commands.md exists; the 'When to Load References' section advertises references/workspaces.md and references/migration.md, which are missing, so 2 of 3 navigation pointers are dead. Signaling is clear, but dead pointers make navigation unreliable, fitting the 2 anchor (structure present but references effectively broken) rather than 3.

Specificity

The description lists multiple concrete actions — 'commands (install, add, remove, update), workspaces, lockfiles, npm/yarn/pnpm migration' — comprehensively covering the package manager domain. It exceeds the 4 anchor because there are no meaningful gaps in capability coverage for a Bun dependency-management skill.

Completeness

It has both a clear 'what' ('commands (install, add, remove, update), workspaces, lockfiles, npm/yarn/pnpm migration') and an explicit 'when' ('Use for dependency management with Bun'). Not a 5 because the 'when' clause is generic — it lacks concrete trigger phrases like 'when the user mentions Bun, npm, yarn, pnpm, or installing packages'.

Trigger Term Quality

Good natural keywords ('install', 'add', 'lockfiles', 'dependency management', 'npm/yarn/pnpm migration'), but a few common phrasings users would naturally say ('add a package', 'update dependencies', 'migrate', 'node_modules', 'bun add') are missing. It falls between the 4 and 5 anchors, closer to 4, since synonyms and command-form variations are not fully covered.

Distinctiveness Conflict Risk

'Bun package manager' plus 'Use for dependency management with Bun' carves a clear niche with explicit Bun scoping, so conflict risk is low. Not a 5 because 'npm/yarn/pnpm migration' could cause the skill to trigger when a user wants help with npm/yarn/pnpm themselves rather than moving to Bun.
