Quality

Content

85%

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

This is a well-structured skill with strong actionability through concrete commands, JSON examples, and YAML output schemas. The workflow is clearly sequenced with proper validation checkpoints and feedback loops. Minor verbosity in execution boundaries and context-disposition policy sections slightly reduces token efficiency, but overall the skill is effective and well-organized.

DimensionReasoningScore

Conciseness

Generally efficient and avoids explaining basic concepts, but some sections like 'Execution Boundaries' and the context-disposition policy paragraph add moderate verbosity. The 'Read when' block and extensive references list could be tighter.

2 / 3

Actionability

Provides concrete, executable bash and jq commands, specific JSON examples showing input defects and fixes, and a clear YAML output schema. The validation command is copy-paste ready and the example demonstrates a real manifest correction.

3 / 3

Workflow Clarity

The 5-step workflow is clearly sequenced with explicit validation checkpoints (step 3: validate before changes, step 5: rerun gate and return evidence). There's a clear feedback loop (validate → patch → revalidate) and a fail-fast directive. The failure mode section adds explicit stop conditions.

3 / 3

Progressive Disclosure

The skill provides a compact overview with well-signaled one-level-deep references to workflow.md, current-codex-plugin-runtime.md, and other reference files. The 'Read when' block clearly signals when to consult each reference. Content is appropriately split between the overview and detailed references.

Description

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 description that clearly defines a specific niche (Codex plugin package verification and hardening) with explicit trigger guidance via the 'Use when' clause. It lists concrete verification targets and uses natural domain-specific terminology that users would employ when needing this skill. The description is concise yet comprehensive, making it easy for Claude to distinguish from other skills.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: hardening, converting, auditing, pre-release checking, verifying manifest paths, bundled skills, hooks, MCP/app config, validation gates, and release blockers. These are detailed and concrete.

3 / 3

Completeness

Clearly answers both what (verifying manifest paths, bundled skills, hooks, MCP/app config, validation gates, release blockers) and when (hardening, converting, auditing, or pre-release checking a Codex plugin package) with an explicit 'Use when' clause.

3 / 3

Trigger Term Quality

Includes strong natural trigger terms users would say: 'hardening', 'converting', 'auditing', 'pre-release checking', 'Codex plugin', 'manifest', 'hooks', 'MCP', 'validation gates', 'release blockers'. Good coverage of domain-specific terms a user working with Codex plugins would naturally use.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive with a clear niche around Codex plugin package verification. The combination of 'Codex plugin', 'manifest paths', 'bundled skills', 'hooks', 'MCP/app config', 'validation gates', and 'release blockers' creates a very specific domain unlikely to conflict with other skills.
