skill-doctor

skill-doctor is a skill for Claude Code, Codex from warpdotdev/common-skills. It costs 55 tokens per session (2,206 once invoked), scanned A, original, MIT.

A local review tool for judging how well an agent setup and its skills work by examining past agent conversations, then suggesting specific improvements.

In plain words
What is it for?
It helps grade installed skills, review conversations from a repository or selected projects, and produce a report with proposed skill changes.
Why use it?
It helps reveal inefficient or low-quality agent behavior that may be hard to notice during individual tasks.

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-doctor 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 6d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (assets/pierre-diffs.js, scripts/collect_sessions.py, scripts/render_report.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.

How it starts

The opening of the file, as written. The whole thing — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.

skill-doctor

Grade the user's agent setup by scoring recent local agent conversations, then propose concrete skill edits and render one shareable report page.

The report can cover conversations in the current repository, conversations in selected projects, or all local conversations. It can evaluate project skills alone or project and global skills together.

Everything runs locally. Never upload transcripts, session files, or any excerpt of them anywhere. The only shareable artifact is the report the user chooses to post.

Let SKILL_ROOT be the directory containing this SKILL.md.

Step 0: Start the run

Verify the executing harness

Read $SKILL_ROOT/references/supported-harnesses.md and identify the harness executing this skill from the runtime context. If it is unsupported or cannot be identified confidently, follow the reference's stop behavior. Do not create a report directory or read conversation history.

Ask which conversations to grade

First check whether the current directory is inside a git repository:

git rev-parse --show-toplevel

Use the harness's user-question tool when available.

When a current repository is available, ask “Which conversations should I grade?” with:

  1. Conversations in this repository — recommended.
  2. All conversations.
  3. Choose projects to analyze.

When there is no current repository, ask the same question with:

  1. All conversations — recommended.
  2. Choose projects to analyze.

If the user chooses projects, ask for one or more project paths. Expand and validate every path as a git repository before continuing. The run produces one combined report across those projects.

Ask which skills to evaluate

Then ask “Which skills should I evaluate?” with:

  1. Project skills + global skills — recommended.
  2. Project skills only.

For an all-conversations run, “Project skills” means skills from local git repositories inferred from the conversations' working directories. After these answers, proceed immediately.

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.
