Conciseness

The body is dense and imperative throughout ('Build the smallest role surface that can be validated from current Codex evidence') with no explanations of concepts Claude already knows, but there is minor redundancy between the Purpose and When to Use sections and slightly padded Discovery Interview bullets ('Explain why this matters for the current skill decision'), fitting the 'minor instances of over-explanation that could be trimmed' anchor rather than the lean top level.

Actionability

Concrete guidance is abundant — exact schema fields ('`description`, `config_file`, and `nickname_candidates`; keep `agents.max_depth >= 1`'), real source anchor paths, and copy-paste validation commands — but some workflow steps remain abstract ('Verify current Codex role schema, `spawn_agent` surface...') and the role template is fully delegated to references, matching 'mostly executable guidance... with minor gaps' rather than fully executable.

Workflow Clarity

The nine-step Workflow is clearly sequenced with validation embedded (step 8) and backed by a dedicated Validation section with an explicit feedback loop ('Stop at the first failed gate, fix that failure class, and rerun it') and concrete gate commands — matching the top anchor's 'explicit validation steps; feedback loops for error recovery'. The destructive/batch cap does not apply since validation is present.

Progressive Disclosure

A clear, sectioned overview with well-signaled, one-level-deep references — role-creation-guide.md, role-config-examples.md, contract.yaml, evals.yaml, and discovery-interview.md all exist in references/ — with template and contract detail appropriately split out and a consolidated References section. This matches the top anchor.

Specificity

Lists five concrete actions ('Create, validate, install, fold, or troubleshoot') applied to specific artifacts ('Codex subagent role TOML, agents-table config, discoverability wiring, and duplicate-role merges'), comprehensively covering the skill's surfaces with no notable gaps — matching the top anchor rather than the 'minor gaps' level 4.

Completeness

Explicitly answers both what (first sentence enumerating concrete actions and artifacts) and when ('Use when a user asks for a Codex agent role, reviewer agent, role config, TOML role file, subagent setup, or overlapping agents to merge') with concrete trigger phrases — a verbatim match for the top anchor.

Trigger Term Quality

The 'Use when' clause supplies six natural triggers a user would plausibly say ('Codex agent role', 'reviewer agent', 'role config', 'TOML role file', 'subagent setup', 'overlapping agents to merge'), but coverage is not comprehensive: no '.toml' file-extension form and few synonyms beyond 'role file/role config'. This fits the 'good keyword coverage; a few natural terms missing' anchor rather than the top level.

Distinctiveness Conflict Risk

'Codex' scoping combined with TOML role files and agents-table config carves a clear niche with distinct triggers; it would not fire for generic agent-creation or document skills, satisfying the 'clear niche with distinct triggers; minimal conflict risk' anchor.
