Conciseness

The body is dense and functional — a routing table, terse operating rules, and a short commands block — with no explanations of concepts Claude already knows. Not 5 because there is mild redundancy: script paths appear in both the routing table and 'Quick commands', and 'Do not use this skill for' partially restates scope already delimited elsewhere.

Actionability

The 'Quick commands' block gives copy-paste-ready invocations whose flags (`--input <path> --json`, `--skill-dir <path>`, `--source-dir skills --skill <name> --agent cursor --scope project --mode symlink`) match the actual argument parsing in the bundled scripts, and the routing table maps every task to a concrete reference file and script. Not 4 because the commands are executable as written and cover the common install/validate/inspect cases.

Workflow Clarity

The six-step workflow is clearly sequenced with an explicit validation checkpoint ('Use `scripts/validate-skill.mjs` before and after installation'), confirmation gates for risky batch operations ('summarize the planned batch operation before execution and wait for confirmation'), and a 'Minimum self-check' checklist for error recovery. This satisfies the feedback-loop expectation for batch/destructive operations, so the workflow-clarity cap does not apply.

Progressive Disclosure

SKILL.md is a clear overview: every referenced path (`references/source-classification.md`, `migration-playbook.md`, `cli-alignment.md`, `install-workflow.md`, `mapping-extension.md`, and the three scripts) exists in the bundle, references are exactly one level deep with no nested pointers, and the routing table plus workflow steps signal exactly when to open each file. Not 4 because navigation is explicit and the split between overview and detail is clean.

Specificity

Lists multiple concrete actions — 'Analyze, standardize, validate, and sync locally maintained skills', 'turn ad-hoc prompt or rules folders into reusable `SKILL.md`-based skills', 'install or sync one or more local skills from `./skills`', 'manage local skill path mappings and symlink or copy installation behavior' — comprehensively covering the skill's capabilities. Not 4 because coverage of the skill's actions is essentially complete rather than having minor gaps.

Completeness

Explicitly answers both: the first sentence states what it does, and 'Use this skill when Codex needs to turn ad-hoc prompt or rules folders into reusable `SKILL.md`-based skills, install or sync ... or manage local skill path mappings' gives concrete trigger phrases. Not 4 because the 'when' clause is explicit and enumerates specific triggering scenarios rather than being merely adequate.

Trigger Term Quality

Good natural-term coverage: 'install', 'sync', 'prompts folder', 'reusable skill', 'symlink or copy', and concrete agent names (Claude, Cursor, CodeBuddy, Codex). Not 5 because a few phrasings users would plausibly say are missing (e.g. 'add a skill to an agent', 'skill library', 'share skills across agents'); not 3 because the included terms map well onto real request phrasing, as echoed by the skill's own 'Common requests'.

Distinctiveness Conflict Risk

A clear niche — locally maintained skills installed from `./skills` with a source-first, `skills` CLI-aligned model — distinguishes it from generic skill-authoring or remote-registry skills. Not 5 because broad install/sync phrasing leaves minor overlap risk with other skill-management or packaging skills.
