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 | $0.00043 | $0.00273 |
| Opus 5 | $0.00022 | $0.00137 |
| Sonnet 5 | $0.00009 | $0.00055 |
| Haiku 4.5 | $0.00004 | $0.00027 |
Grade B, and why
doctor scanned grade B with 1 finding 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 10d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
…or whatever the actual install path is — find it via `readlink ~/.claude/plugins/captain-memo`. What it actually says
Captain Memo — doctor (health probe)
When invoked, run a comprehensive health check and report PASS/WARN/FAIL for each component, with one-line remediation hints when something's not green.
What to do
The CLI has the canonical implementation. Just shell out:
captain-memo doctor
…and pass the output back to the user verbatim (it's already nicely formatted with colour and remediation hints).
If captain-memo isn't on PATH, fall back to:
/home/kalin/projects/captain-memo/bin/captain-memo doctor
…or whatever the actual install path is — find it via readlink ~/.claude/plugins/captain-memo.
On error
If even the CLI invocation fails, that's a sign something is broken at the install layer. Suggest:
ls ~/.claude/plugins/captain-memo
systemctl --user list-units 'captain-memo-*'
…to see whether the install ever happened, then captain-memo install if not.
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 kalinbogatzevski/captain-memo (3 stars, last pushed 7d ago), licensed Apache-2.0. It adds 43 tokens to every session and 273 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
