skill-quality-scorer

skill-quality-scorer is a skill for Claude Code, Codex from aristoteleo/awesome-skill-generate. It costs 77 tokens per session (1,144 once invoked), scanned A, original, BSD-2-Clause.

A reviewer that evaluates a Codex skill across several quality criteria and produces a structured score, verdict, and revision advice. A skill is a set of instructions that tells a coding agent how to perform a task.

In plain words
What is it for?
Use it to review a SKILL.md, skill folder, proposed changes, or two competing skill designs. It writes a Markdown score report in the current working directory.
Why use it?
It helps reveal unclear triggers, incomplete instructions, wasted context, weak validation, or claims that do not match the actual tools and workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

skill-quality-scorer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/inspect_python_interface.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Skill Quality Scorer

Goal

Score a skill on quality, not domain sophistication. Review whether another agent could trigger and use the skill reliably with minimal ambiguity and minimal context waste.

Quick Workflow

  1. Read the target SKILL.md.
  2. If the skill documents a real callable or CLI, inspect the live interface before trusting notebook-derived claims.
  3. For data workflows, try to follow the skill on representative data before final scoring.
  4. Read only the referenced files needed to judge execution quality, resource partitioning, validation quality, source grounding, and empirical executability.
  5. Score each required dimension using references/rubric.md.
  6. Apply hard gates before computing the final verdict.
  7. Return a compact scorecard plus the highest-signal revision guidance.
  8. For every dimension score, include an explicit rationale directly under that score in the report.
  9. Write a human-readable Markdown score report to the current working directory instead of hiding it inside the generated skill folder.

Scope

Use this skill to review:

  • a skill folder
  • a standalone SKILL.md
  • a proposed skill diff
  • two competing skill designs
  • a notebook-derived skill after conversion

Do not score:

  • the scientific correctness of the underlying domain unless the skill itself makes unsupported domain claims
  • code quality outside the skill's own bundled scripts and instructions
  • repository-wide documentation unrelated to the skill

Review Rules

  • Default to reading SKILL.md first.
  • Read references/ only when the main skill explicitly depends on them or when resource partitioning is being scored.
  • Read scripts/ only when the skill relies on them for core execution or validation.
  • When the skill claims concrete function or CLI behavior, verify that behavior against source, help(...), or -h/--help before treating the skill as complete.
  • For notebook-derived data workflows, do not stop at interface inspection if representative data can be constructed or loaded reasonably.
  • Treat missing branch coverage for method, backend, mode, provider, or similar parameters as a real usability risk, not a minor omission.
  • Do not reward verbosity.
  • Do not reward domain difficulty.
  • Do not assume missing validation or compatibility notes are present elsewhere.
  • Penalize trigger ambiguity, execution ambiguity, and hidden dependencies aggressively.

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
