brief

brief is a skill for Claude Code, Codex from 7xuanlu/wenlan. It costs 50 tokens per session (839 once invoked), scanned B, original, Apache-2.0.

A workflow for reviewing pending Wenlan captures, revisions, or daemon refinements after a briefing or handoff.

In plain words
What is it for?
Listing up to four pending items, then accepting, dismissing, skipping, or editing them after the user gives explicit instructions.
Why use it?
It prevents unapproved changes by requiring a clear decision for each item and showing the queue in small batches.

Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

brief 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/brief

Read one Space's current project snapshot. The daemon Brief is authoritative; ~/.wenlan/sessions/_status/*.md is only a one-way human-readable receipt and must never be read as product state.

1. Resolve the Space

raw_args="<the full argument string passed to /brief>"
space_arg="$(printf '%s\n' "$raw_args" | grep -oE 'space:[A-Za-z0-9_-]+' | head -1 | cut -d: -f2)"
topic_arg="$(printf '%s\n' "$raw_args" | sed -E 's/[[:space:]]*space:[A-Za-z0-9_-]+[[:space:]]*/ /g' | sed -E 's/^[[:space:]]+|[[:space:]]+$//g')"
# The resolver ships inside the installed plugin; the relative path only
# exists in a wenlan checkout.
resolver="$(find "$HOME/.codex/plugins/cache" -path '*/wenlan/*/bin/resolve-space.sh' 2>/dev/null | head -1)"
resolved="$("${resolver:-plugin-codex/bin/resolve-space.sh}" --cwd "$PWD" ${space_arg:+--arg "$space_arg"} 2>/dev/null)"
space="$(printf '%s\n' "$resolved" | cut -f1)"
source_layer="$(printf '%s\n' "$resolved" | cut -f2)"

Print Resolved space: <space> (from <source-layer>). If no Space resolves, print Resolved space: none (unscoped) and omit space.

2. Read the Brief

Call:

mcp__wenlan__brief(
  topic="<topic_arg only when the user supplied one>",
  space="<resolved only when non-empty>"
)

Do not invent or infer a topic when the argument is absent. No topic means the complete Brief alone. A topic means the same complete Brief plus a separate Related Context section scoped to that Space.

Brief reads never create state. If the state is brief_not_created, explain that the first /handoff update will create it. If the state is space_not_resolved, ask for a Space only when the working directory and configuration cannot resolve one safely.

Render the last-session summary, Active, Backlog, then Related Context only when returned. Keep stable item IDs and versions available for later /handoff reconciliation, but omit them from the normal user-facing list.

3. Pending revisions

Call:

mcp__wenlan__list_pending_revisions(limit=10)

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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 is a skill published in the GitHub repository 7xuanlu/wenlan (64 stars, last pushed today), licensed Apache-2.0. It adds 50 tokens to every session and 839 once invoked, about $0.0003 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 2026-08-30.
