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 | $0.00058 | $0.03776 |
| Opus 5.5 | $0.00023 | $0.01510 |
| Sonnet 5.5 | $0.00012 | $0.00755 |
| Haiku 4.5 | $0.00006 | $0.00378 |
Grade A, and why
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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 283 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/learning-loop:doctor
A read-mostly diagnostic. Runs the health-check library, presents the result, and walks you through fixes one at a time.
If invoked with --redact, skip the normal health-check steps and run the Redact mode section instead.
Paths
Resolve PLUGIN_DATA, VAULT, and the plugin root per ${CLAUDE_PLUGIN_ROOT}/skills-shared/paths-preamble.md (read it and apply).
fix strings in the health-check JSON prefix paths with a user-facing PLUGIN shorthand for the plugin root (defined in guide/troubleshooting.md; the guide/ tree is not shipped with the plugin). Show them verbatim when the user will run the command; substitute ${CLAUDE_PLUGIN_ROOT} for the leading PLUGIN segment when you execute it yourself via Bash.
Step 1: Run all checks
node ${CLAUDE_PLUGIN_ROOT}/scripts/health-check.mjs --full --json
Parse the JSON. The schema:
{
"ts": "...",
"ran": "full",
"checks": [
{ "id", "name", "status": "ok" | "fail", "severity": "ok" | "warn" | "fail", "detail", "fix" }
]
}
Step 2: Present the report
Format the dashboard like this:
learning-loop doctor
====================
Health checks (N passed, M warnings, F issues):
✓ Node.js v25.9.0
✓ Claude Code 2.1.145
⚠ ~/.local/bin on PATH not on PATH
→ Add to your shell rc: export PATH="$HOME/.local/bin:$PATH"
✗ ll-search binary missing at /Users/.../bin/ll-search
→ Run /learning-loop:init to re-download the binary
…
F issues, M warnings.
Icon rules:
✓whenstatus === "ok"⚠whenstatus === "fail" && severity === "warn"✗whenstatus === "fail" && severity === "fail"
Step 3: If F + M === 0
Print ✓ All checks pass. Nothing to fix. and exit.
Step 4: Otherwise, iterate fails first, then warns
For each check with status === "fail":
- Show the check:
✗ <name>: <detail> Suggested fix: <fix> - Ask via
AskUserQuestion:- Option A:
Fix this (auto-runnable)— only when the fix is in the auto-runnable table below - Option A':
Run the suggested command and tell me when done— when the fix is manual - Option B:
Skip — I'll handle this later - Option C:
Stop the doctor session— exits cleanly
- Option A:
- On choice A: execute the corresponding fix command via Bash. After it finishes, re-run
node ${CLAUDE_PLUGIN_ROOT}/scripts/health-check.mjs --full --jsonand find the same check by itsidfield. Report:✓ Fixed (new state: <detail>)if the check now returns ok⚠ Still warning: <new detail>if it improved to warn✗ Still failing: <new detail>if it didn't help (don't loop — move on)
- On choice A' (manual): print the command, then ask
Done? [Y]es / [N]o. On Yes, re-runnode ${CLAUDE_PLUGIN_ROOT}/scripts/health-check.mjs --full --jsonand find the same check by itsidfield, then report as above. - On choice B: track as skipped and move to next.
- On choice C: print summary and exit.
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.

doctor is a skill published in the GitHub repository robinslange/learning-loop (13 stars, last pushed 4d ago), licensed Apache-2.0. It adds 58 tokens to every session and 3,776 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
