brief

brief is a skill for Claude Code, Codex from gtapps/claude-code-hermit. It costs 62 tokens per session (2,882 once invoked), scanned A, original, MIT.

A short status report for recent work in the current coding session, or in the latest saved report if the session is unavailable. It is intended for quick updates such as a morning or evening check-in.

In plain words
What is it for?
Use it when you ask for a brief, progress update, morning update, evening update, or a summary of what happened. It reports recent session activity and can follow the project's notification rules.
Why use it?
It removes the need to reconstruct recent activity from many messages or files. It gives the operator a compact view of what happened and what is currently active.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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 A, and why

brief 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 today.

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 — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Session Brief

Provide a concise executive summary of recent session activity. Designed for morning check-ins, phone/channel consumption, and quick status updates.

Always-On Delivery Rule

If config.always_on is true, deliver all operator-facing output per CLAUDE-APPEND.md § Operator Notification. The terminal is unmonitored in always-on mode. For the push-fallback branch, condense the brief to a single line (per § Operator Notification push format): include whichever of open proposal count and active heartbeat alerts are present and non-zero; omit zero or unavailable fields. Example: Brief: 16 proposals open, 1 alert — open CC to view. In interactive mode, output to terminal. This applies to all flags below.

Dispatch

Before composing any brief, determine the dispatch mode:

  1. Read session_state from .claude-code-hermit/state/runtime.json (live state — always in main).
  2. Resolve the active flag (--morning, --evening, "brief today"/"daily summary", or no flag).

Live files (SHELL.md, alert-state.json, proposals/) are read fresh on this turn; a value held in context from before a compaction is stale.

Dispatch decision:

  • --morning → dispatch (mode: morning)
  • --evening → dispatch (mode: evening)
  • "brief today" / "daily summary" / "what happened today" → dispatch (mode: daily)
  • No flag + session_state is in_progressno dispatch — summarize the live SHELL.md in main (Plan step 1a)
  • No flag + session_state is idleno dispatch — read the live SHELL.md in main and emit the idle block (Plan step 1b)
  • No flag + no active session (no SHELL.md / no session_state) → dispatch (mode: default-no-session, Plan step 1c)

For dispatching modes: invoke claude-code-hermit:skill-eval-runner pointed at ${CLAUDE_PLUGIN_ROOT}/skills/brief/reference.md. Pass in the dispatch prompt: mode (one of the values above), today (current ISO date), and for morning only: context_recovery (set to true if auto-memory seems sparse — new instance, fresh machine — false otherwise).

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 gtapps/claude-code-hermit (73 stars, last pushed today), licensed MIT. It adds 62 tokens to every session and 2,882 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
