minutes-brief

minutes-brief is a skill for Codex from silverstein/minutes. It costs 150 tokens per session (2,936 once invoked), scanned D, original, MIT.

A quick briefing made before a meeting that finds the next calendar event and summarizes relevant relationship history and open commitments. It is designed as a one-page overview you can read shortly before a call.

In plain words
What is it for?
Use it to prepare for an upcoming call, review someone’s history and outstanding commitments, and get a concise factual briefing about the meeting.
Why use it?
It gathers useful background without requiring an interactive preparation session. This reduces the need to search past meetings and calendar details at the last minute.

About the project

Minutes is an open-source, local-first meeting recorder that transcribes meetings, calls, and voice memos on the device and stores the results as Markdown files. It is for people who want their meeting records available to Claude Code, Codex, Cursor, and other MCP clients without uploading them. The catalogue add-ons extend agent workflows for querying and using those local meeting files.

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 D, and why

minutes-brief scanned grade D with 2 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 11d 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.

Tells the agent never to refusehighAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

- **If the user types two names, ask once.** "brief me on Sarah and Alex" — pick one as the focus and tell the user. "I'll focus the brief on Sarah since you have more history with her, and mention Alex briefly." Don't r

How it starts

The opening of the file, as written. The whole thing — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill Path

Before running helper scripts or opening bundled references, set:

export MINUTES_SKILLS_ROOT="$(git rev-parse --show-toplevel)/.agents/skills/minutes"
export MINUTES_SKILL_ROOT="$MINUTES_SKILLS_ROOT/minutes-brief"

/minutes-brief

Fast, non-interactive briefing that synthesizes your relationship history with someone into a one-page brief — designed so you can read it in 60 seconds before walking into a call.

This is the proactive layer. It's built to be invoked silently by a hook (e.g., 15 min before a calendar event) and to also work as a manual /minutes-brief command. Unlike /minutes-prep, brief asks no questions and sets no goals — it just hands you the facts.

How it works

Phase 0: Determine the target

Three ways the user can invoke this:

1. With a name (/minutes-brief sarah, "brief me on Alex") → Use that name directly. Before searching, check for learned aliases:

node "$MINUTES_SKILLS_ROOT/_runtime/hooks/lib/minutes-learn-cli.mjs" aliases "<name>" 2>/dev/null

If aliases exist, search across all returned variants and treat them as the same person for the rest of the flow. If the user explicitly says two names are the same person, persist it:

node "$MINUTES_SKILLS_ROOT/_runtime/hooks/lib/minutes-learn-cli.mjs" set-alias "Sarah Chen" "Sarah" "User confirmed these refer to the same person"

Then skip to Phase 1.

2. With "auto" or no argument (/minutes-brief, "brief me on my next call") → Auto-detect the next upcoming calendar event. Try sources in order — use the first that works:

  • Google Calendar MCP (best — Claude users):

    gcal_list_events(timeMin: "<now ISO>", timeMax: "<+2hr ISO>", condenseEventDetails: false)
    

    Filter to events with 2+ attendees, skip all-day events, pick the soonest. Pull attendee names from the event.

  • gog CLI (if installed):

    gog calendar list --today --json 2>/dev/null
    
  • Apple Calendar via osascript (every Mac, zero install):

    osascript -e 'tell application "Calendar" to get {summary, start date} of (every event of every calendar whose start date >= (current date) and start date < ((current date) + 2 * hours))'

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.
