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 | $0.00034 | $0.00402 |
| Opus 5 | $0.00017 | $0.00201 |
| Sonnet 5 | $0.00007 | $0.00080 |
| Haiku 4.5 | $0.00003 | $0.00040 |
Grade A, and why
observations scanned grade A 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 9d 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.

Captain Memo — recent observations
When the user invokes this skill, they want a quick view of recent session observations — the structured "voyage logs" the Stop hook produces.
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:
curl -s "http://127.0.0.1:39888/observations/recent?limit=<LIMIT>" | jq '.'
- The response is
{ items: [{id, session_id, prompt_number, type, title, created_at_epoch}] }.
Output format
Recent observations (N total):
2026-05-07 14:32 [bugfix ] Fix off-by-one in billing pro-ration loop
session=ses_..._abc123 · prompt#1 · id=42
2026-05-07 14:18 [feature ] Add NetLine SPM rule 75 for Pernik discount
session=ses_..._xyz890 · prompt#3 · id=41
…
Format created_at_epoch as a UTC date in the user's timezone. Pad [type] to 10 chars for alignment.
If empty
Say something like:
"No observations yet. Captain Memo's

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 (3 stars, last pushed 5d ago), licensed Apache-2.0. It adds 34 tokens to every session and 402 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

Opt in to memem's event-triggered mining. New sessions are mined automatically via the Stop hook.
knowledge-base
Build and maintain a company knowledge base as a wiki of interlinked markdown notes in the workspace — a private, compounding Wikipedia. Use when the user wants to start or organize a knowledge base / wiki, ingest sources (URLs, documents, pasted notes) into it, ask questions answered from it, or audit (lint) it.…

Delete a Wenlan memory by exact id from Codex. Destructive and confirmation gated. Invoked as /forget .
vault-for-llm
Connect OpenClaw to Vault Agent Memory as a local-first governed project memory layer. Search first, then bounded-read cited source ranges; propose new memories as candidates instead of writing directly into active memory.

Your next session starts cold. No memory of what you built, what broke, what you decided. Every memory you write is a gift to that future session. The richer the memory, the less time re-learning.
memem-welcome
Re-show the full memem welcome screen regardless of whether the user has seen it before. Use when the user wants to see the intro, tutorial, or welcome again.
