Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00023 | $0.00264 |
| Opus 5 | $0.00012 | $0.00132 |
| Sonnet 5 | $0.00005 | $0.00053 |
| Haiku 4.5 | $0.00002 | $0.00026 |
Grade A, and why
feature-doctor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Run the workspace preflight doctor and act on it. It's read-only — it verifies everything the
workspace skill needs before building:
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/doctor.py" $ARGUMENTS
Then handle the results, splitting by the owner tag the doctor prints:
[agent]— do it yourself now (create.claude/feature/config.json,brew install ghif missing — say you're doing it), then re-run the doctor.[user]— you can't do these; relay the exact command verbatim (gh auth login,proxy-setup.shfor pretty URLs, cloning a missing repo, installing a repo's dev deps).
Exit 1 means a [user] action blocks building — surface those lines clearly. Warnings
(dev-server deps, Caddy) are non-blocking: note them and how to enable them. Run from the workspace
root (the script self-anchors), or pass --root DIR.
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.

feature-doctor is a command published in the GitHub repository fivol/claude-make-better (5 stars, last pushed 1mo ago), licensed MIT. It adds 23 tokens to every session and 264 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
