Conciseness

The body is lean and operational with no padding or explanation of concepts Claude already knows ('Do not infer new CLI behavior from this card; the implementation is authoritative'). Minor trimming is possible: the interactive/non-interactive distinction is repeated across sections ('non-interactive runs do not block', 'non-interactive runs preserve it', 'non-interactive runs preserve existing files'), and bullets like the '--merge-agents' selector line pack layered caveats into single run-on sentences.

Actionability

Guidance is fully executable: copy-paste commands ('omx setup --force --verbose', 'omx doctor', 'npm run build' followed by 'node dist/cli/omx.js setup --force --verbose'), exact flag spellings and semantics, and a concrete scope/mode resolution procedure with an explicit discovery path ('${CODEX_HOME:-~/.codex}/plugins/cache/**/.codex-plugin/plugin.json with name: oh-my-codex'). Common cases (installed CLI vs local source, plugin vs legacy) are each covered.

Workflow Clarity

The sequence is clearly organized (resolve scope/mode in numbered steps, run setup, verify, troubleshoot, report) with an explicit validation checkpoint ('Expect doctor evidence for prompts and skills in the selected scope, project-root AGENTS.md, .omx/state, and CLI-first config'). The exit contract provides a feedback loop for error recovery ('on failure preserve the exact command output and rerun the smallest corrective command') and a stop checklist ('Do not claim installation from a dry-run alone'), which satisfies validation requirements for this mutating operation.

Progressive Disclosure

The body is roughly 54 lines, well-sectioned under clear headers, with a single clearly-signaled one-level-deep reference ('Shared safety, lifecycle, hook, team, autonomy, and cancellation rules live in templates/AGENTS.md'). No bundle files exist or are needed, so the well-organized section structure fully meets the short-skill bar.

Specificity

The description names the domain ('oh-my-codex') but the actions are generic: 'Setup and configure' are near-synonymous catch-all verbs with no concrete actions such as installing prompts/agents/skills or merging config.toml. It fits anchor 2 ('Names the domain but actions are minimal or generic'), not anchor 3, which requires 1-2 concrete named actions.

Completeness

The 'what' is stated ('Setup and configure oh-my-codex using current CLI behavior') but the 'when' is entirely absent — there is no 'Use when...' clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. It is above anchor 2 because the 'what' is not vague; it clearly identifies the tool and task.

Trigger Term Quality

Some relevant natural terms are present ('Setup', 'configure', 'oh-my-codex') but common variations users would actually say are missing: 'install', 'initialize', 'refresh', and the 'OMX' abbreviation used throughout the body. This matches anchor 3 ('Some relevant keywords but missing common variations or synonyms') rather than 4, since the most likely user phrasing ('install omx') is absent.

Distinctiveness Conflict Risk

Naming the specific tool 'oh-my-codex' gives a clear niche unlikely to trigger unrelated skills, but the generic 'Setup and configure' framing creates minor overlap risk with closely related sibling skills the body itself hints at (doctor, update, agents-init). It fits anchor 4 ('Mostly distinct; minor overlap risk with closely related skills') rather than 5, which requires distinct trigger phrases that are absent.
