Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00145 | $0.01681 |
| Opus 5.5 | $0.00058 | $0.00672 |
| Sonnet 5.5 | $0.00029 | $0.00336 |
| Haiku 4.5 | $0.00015 | $0.00168 |
Grade A, and why
brief-me 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 2d 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brief Me — DEPRECATED
This skill is deprecated. Use
/where-are-weinstead.If someone has invoked this, tell them in one line that it is retired, then run
/where-are-wefor them. Run the brief below only if they explicitly ask for this one anyway.Why it was retired.
/where-are-wecovers the same re-entry case and scales to the gap: it checks how long the user has been away, gives just done and left to someone who is still active, and adds a paragraph on what the task is for someone who has been gone. Six fixed headings were more than most re-entries needed.
The user has come back to this session with weak or no memory of it. Reading the last message will not fix that: the last message was written for someone who was here five minutes ago. It leans on pronouns, on shorthand coined mid-session, and on file names introduced hours back. It continues the thread; it does not introduce it.
Produce one short briefing that puts them back in the chair. Then stop.
1. Check the state before you narrate
The failure mode of this skill is a fluent, confident, wrong story. Guard against it by reading the real state first, not your memory of it:
git statusandgit diff --statagainst the base branch — what is actually changed, and is anything half-applied?git logfor recent commits, and the current branch name.- Any plan, spec, or todo file written during this session, and the active todo list.
- Whether tests were run, and what they said.
Then hold two categories apart as you write. A claim backed by disk or git is stated flat. A claim recalled from the conversation and not checkable is marked as recalled, with the check named. Never assert a piece of work is finished without confirming the file exists.
2. The brief
Six headings, in this order. The whole thing fits on one screen.
In one line — the entire session in one sentence a stranger could follow.
What we're doing — the goal in plain terms, one or two sentences. This thread, not the codebase.
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.

brief-me is a skill published in the GitHub repository adamlinscott/claude-skills (3 stars, last pushed 2d ago), licensed MIT. It adds 145 tokens to every session and 1,681 once invoked, about $0.0006 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
session
Session lifecycle management. Parent skill for session-related skills: learning (pattern extraction) and compact (context compression).
vault
Context vault operations: read/update todos, add log entries, search vault content, read strategy/project docs, update project files. Use when user says "vault", "add todo", "update todos", "log entry", "search vault", "check todos", "context vault", "add to log", or any operation on a personal context vault.
handoff
Generate a HANDOFF.md that captures goal, current state, files touched, failed attempts, and next steps — so a fresh Claude session can continue exactly where this one left off. Use when sessions are getting long, Claude keeps retrying the same broken solution, or the user wants to step away and resume later.
moai-factory-foreman
One unattended factory foreman iteration: watch the backlog queue, dispatch the next operator-picked card to an isolated worker, collect completion evidence on read (not on claims), and report. This is the body the project's loop.md driver invokes each iteration of a bare /loop; it can also be invoked directly to test…
daily-briefing
Proactive daily briefing that fires on a recurring schedule, pulls recent memory and workspace context, composes a structured summary (action items, progress, radar, next steps), and delivers it to all active channels. Enable with a time like "set up my daily briefing at 9am". Disable, reschedule, or check status at…
moai-foundation-context
Manages context window optimization, session state persistence, and token budget allocation for multi-agent workflows. Use for token budget management, context limits, or session handoff across agents.
