Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00030 | $0.00424 |
| Opus 5.5 | $0.00012 | $0.00170 |
| Sonnet 5.5 | $0.00006 | $0.00085 |
| Haiku 4.5 | $0.00003 | $0.00042 |
Grade A, and why
observations 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 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.
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
Captain Memo — recent observations
When the user invokes this skill, they want a quick view of recent session observations — the structured "voyage logs" the summarizer writes from a session's tool events.
What to do
- Parse the user's argument as
--limit N(default 20). If they typed/captain-memo:observations 50, treat 50 as the limit. - Run:
captain-memo observation list --limit <LIMIT>
The CLI sends the worker's secret for you: there is no token to handle. If captain-memo is not on PATH, use the shim and checkout fallbacks described in the doctor skill. With no CLI at all (a plugin-only install), call the MCP tool search_observations with a query instead; it has no plain "recent" listing.
- Pass the output back as it is. It is one line per observation, newest first, then a row count.

The timestamp is UTC. For a hit worth reading in full, search_observations or search_all returns its doc_id and get_full opens it.
If empty
Say something like:
"No observations yet. Tool events are summarised shortly after each turn, so an empty list usually means no session has run since installing, or no summarizer is live —
captain-memo statsshows which one is live,captain-memo doctorsays why it is 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.

observations is a skill published in the GitHub repository kalinbogatzevski/captain-memo (5 stars, last pushed 2d ago), licensed Apache-2.0. It adds 30 tokens to every session and 424 once invoked, about $0.0001 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 2026-08-31.
Other skills, from other repositories
memem-mine
Opt in to memem's event-triggered mining. New sessions are mined automatically via the Stop hook.
wenlan-capture
Save a memory to Wenlan in flow, or save something from this conversation as one note when the user asks for a note. Use proactively when the user states a preference, makes a decision, corrects you, or shares a durable fact. Invoked as /wenlan-capture .
wenlan-handoff
End a work session. Stores durable captures, writes a narrative session log, and automatically applies typed item-level deltas to the current Space Brief. Invoked as /wenlan-handoff.
curate
Power-user audit of Wenlan's pending surfaces: accept or dismiss pending revisions (conflicts/merges), or audit pending captures (not yet confirmed). Most users want /brief for revisions; that handles the daily flow. Use /wenlan curate only for explicit deep-walk audits after bulk imports, or to walk the full queue…
wenlan
A single command entry point for Wenlan, a tool that checks its setup and connection and turns stored memories into notes. It can also open or list notes and report its current status.
pages
Browse, open, or print distilled pages, reusing the wenlan pages CLI for the actual open (one implementation on your PATH, no setup). /wenlan pages opens the page when one matches, or shows a small native picker when 2-4 match. /wenlan pages --print reads the page here instead of opening an editor. /wenlan pages lists…
