codex-agent-creator

Create, validate, install, fold, or troubleshoot Codex subagent role TOML, agents-table config, discoverability wiring, and duplicate-role merges. Use when a user asks for a Codex agent role, reviewer agent, role config, TOML role file, subagent setup, or overlapping agents to merge.

Quality

Content

85%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is well-structured: concise imperative guidance, concrete commands, a gated validation workflow, and clean one-level-deep progressive disclosure with all references present. Main opportunity is tightening the densest nominal-phrase sections and converting a few policy statements into runnable steps.

Suggestions

Convert remaining policy statements (e.g. 'Narrow each role request to one primary surface before editing') into a concrete decision procedure or command so the guidance is fully runnable.

Tighten the Inputs and Execution Boundaries sections by merging overlapping constraints into a single checklist to reduce nominal-phrase density.

DimensionReasoningScore

Conciseness

Dense imperative prose that assumes Claude's competence with no basic-concept padding; a few nominal-phrase-heavy sections could be trimmed to reach the lean 5-anchor ideal.

4 / 5

Actionability

Provides concrete executable commands ('./bin/ask skills audit ...', 'python3 ...validate_he_subagent_routing.py') and schema specifics (e.g. 'agents.max_depth >= 1'), though some guidance is policy-level rather than runnable, leaving minor gaps.

4 / 5

Workflow Clarity

Nine-step numbered workflow with explicit validation checkpoints ('Stop at the first failed gate, fix that failure class, and rerun it') and a feedback loop; appropriate validation for this repo-write skill.

5 / 5

Progressive Disclosure

Overview body points to one-level-deep references, all of which exist as real bundle files (role-creation-guide.md, role-config-examples.md, contract.yaml, evals.yaml, discovery-interview.md), with a clear References section for navigation.

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is strong: concrete multi-action capability list, explicit 'Use when' triggers in third person, and a clear niche that minimizes conflict risk. The only slight gap is that trigger terms favor internal jargon over everyday user phrasing and lack file-extension/synonym breadth.

Suggestions

Add everyday phrasings and file extensions to the triggers (e.g., '.toml role files', 'set up a subagent', 'merge duplicate agents') to round out the natural-term coverage.

Consider leading with the most common user phrasing before the technical surfaces so the most frequent trigger is front-loaded.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('Create, validate, install, fold, or troubleshoot') across several distinct surfaces (TOML, agents-table config, discoverability wiring, merges), matching the comprehensive-coverage anchor.

5 / 5

Completeness

Explicitly answers both what (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').

5 / 5

Trigger Term Quality

Strong natural triggers ('Codex agent role', 'reviewer agent', 'role config', 'TOML role file', 'subagent setup', 'overlapping agents to merge'), but leans on internal jargon rather than full synonym/file-extension breadth of the top anchor.

4 / 5

Distinctiveness Conflict Risk

Narrow Codex-subagent-role niche with distinct triggers makes it unlikely to fire for unrelated skills.
