codex-agent-creator
Create, validate, install, fold, or troubleshoot Codex custom subagent roles, role TOML config files, agent configuration, custom roles, subagent setup, and discoverability wiring. Use when a user asks for a Codex agent role, reviewer agent, role config, TOML role file, or overlapping agents to merge.

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong skill description that clearly articulates specific actions (create, validate, install, fold, troubleshoot), targets a well-defined domain (Codex custom subagent roles and TOML configuration), and includes an explicit 'Use when' clause with natural trigger terms. The description is concise, uses third-person voice, and occupies a distinct niche that minimizes conflict risk with other skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'create, validate, install, fold, or troubleshoot' applied to well-defined objects like 'Codex custom subagent roles, role TOML config files, agent configuration, discoverability wiring.' | 3 / 3 |
Completeness | Clearly answers both 'what' (create, validate, install, fold, troubleshoot Codex custom subagent roles and config files) and 'when' with an explicit 'Use when...' clause listing specific trigger scenarios like asking for a role config, TOML role file, or merging overlapping agents. | 3 / 3 |
Trigger Term Quality | Includes a strong set of natural keywords users would say: 'Codex agent role', 'reviewer agent', 'role config', 'TOML role file', 'overlapping agents to merge', 'subagent setup'. These cover multiple natural phrasings a user might employ. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive niche focused specifically on Codex custom subagent roles and TOML config files. The domain-specific terminology ('Codex', 'subagent', 'TOML role file', 'discoverability wiring') makes it very unlikely to conflict with other skills. | 3 / 3 |

Implementation
62%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill demonstrates strong workflow design with clear sequencing, validation gates, and a stop-fix-rerun feedback loop. However, it heavily depends on external reference files for its most actionable content (templates, examples, config shapes) while providing none inline, making the SKILL.md itself more of an abstract routing document than a self-contained guide. The content is reasonably concise but could be tightened in places where sections overlap.
Suggestions
Include at least one minimal, copy-paste-ready TOML role file example directly in the SKILL.md body rather than deferring all concrete examples to references/role-config-examples.md.
Add a concrete input/output example showing what a role creation request looks like and what the expected output (TOML + validation report) should contain.
Consolidate overlapping sections (Anti-Patterns, Gotchas, Failure Mode) to reduce redundancy and improve token efficiency.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is moderately efficient but includes some sections that feel redundant or could be tightened (e.g., 'Philosophy' restates Purpose, 'Failure Mode' and 'Anti-Patterns' overlap with validation gates). Some bullet points are dense but not padded with things Claude already knows, so it avoids the worst verbosity. | 2 / 3 |
Actionability | The procedure provides a clear sequence of steps and references external files for copyable templates, but the skill itself contains no executable code, no concrete TOML examples, and no copy-paste-ready config snippets. The examples section gives only natural language prompts, not input/output pairs. Key actionable content is deferred to references that aren't provided. | 2 / 3 |
Workflow Clarity | The 8-step procedure is clearly sequenced with classification, routing, verification, inventory, action, minimal edit, validation, and reporting. The validation gates section explicitly defines a stop-on-first-failure feedback loop (fix and rerun), which is appropriate for this kind of config manipulation work. | 3 / 3 |
Progressive Disclosure | The skill references multiple external files (discovery-interview.md, role-config-examples.md, role-creation-guide.md, contract.yaml, evals.yaml) with clear signaling and one-level-deep links, which is good structure. However, no bundle files were provided, so the critical actionable content (copyable templates, confidence bands, discovery interview) cannot be verified to exist, and the main file itself lacks enough standalone substance without them. | 2 / 3 |
Total | 9 / 12 Passed |
