Briefing Skill

Compile a daily briefing from brain context.

Filing rule: When the briefing creates or updates brain pages, follow

skills/_brain-filing-rules.md

.

Contract

• Every fact in the briefing includes an inline

  [Source: slug, updated DATE]

  citation.
• Meeting participants are resolved against the brain; gaps are explicitly flagged.
• Active deals and action items include deadlines and recency context.
• The briefing is read-only: no brain pages are created or modified unless the user explicitly requests it.
• Stale alerts surface pages relevant to today's context, not just all stale pages.

Phases

1. Today's meetings. For each meeting on the calendar:
   • Search gbrain for each participant by name
   • Read their pages from gbrain for compiled_truth context
   • Summarize: who they are, recent timeline, relationship to you
2. Active deals. List deal pages in gbrain filtered to active status:
   • Deadlines approaching in the next 7 days
   • Recent timeline entries (last 7 days)
3. Time-sensitive threads. Open items from timeline entries:
   • Items with deadlines in the next 48 hours
   • Follow-ups that are overdue
4. Recent changes. Pages updated in the last 24 hours:
   • What changed and why (read timeline entries from gbrain)
5. People in play. List person pages in gbrain sorted by recency:
   • Updated in last 7 days
   • Have high activity (many recent timeline entries)
6. Stale alerts. From gbrain health check:
   • Pages flagged as stale that are relevant to today's meetings

GBrain-Native Context Loading

Before generating any briefing, load context from gbrain systematically.

Before a meeting

For every attendee on the calendar invite:

• gbrain search "<attendee name>"

  -- find their brain page

• gbrain get <slug>

  -- load compiled truth, recent timeline, relationship context
• If no page exists, note the gap ("No brain page for Sarah Chen -- consider enrichment")

Before an email reply

Before drafting or triaging any email:

• gbrain search "<sender name>"

  -- load sender context
• Read their compiled truth to understand who they are, what they care about, and your relationship history. This turns a cold reply into an informed one.

Daily briefing queries

Run these queries to populate the briefing sections:

• gbrain query "active deals status"

  -- deal pipeline snapshot

• gbrain query "meetings this week"

  -- recent meeting pages with insights

• gbrain query "pending commitments follow-ups"

  -- open threads and action items

• gbrain search --type person --sort updated --limit 10

  -- people in play

Output Format

DAILY BRIEFING -- [date]
========================

MEETINGS TODAY
- [time] [meeting name]
  Participants: [name] (slug: people/name, [key context])

ACTIVE DEALS
- [deal name] -- [status], deadline: [date]
  Recent: [latest timeline entry]

ACTION ITEMS
- [item] -- due [date], related to [slug]

RECENT CHANGES (24h)
- [slug] -- [what changed]

PEOPLE IN PLAY
- [name] -- [why they're active]

Back-Linking During Briefing

If the briefing creates or updates any brain pages (e.g., new meeting prep pages, updated entity pages), the back-linking iron law applies: every entity mentioned must have a back-link from their page. See

skills/_brain-filing-rules.md

.

Citation in Briefings

When presenting facts from brain pages, include inline citations:

• "Jane is CTO of Acme [Source: people/jane-doe, updated 2026-04-01]"
• This lets the user trace any claim back to the brain page and assess freshness

Anti-Patterns

• Briefing without brain queries. Never generate a briefing from memory alone; always query gbrain for current data.
• Uncited facts. Every claim must include

  [Source: slug, updated DATE]

  . A fact without a citation is unverifiable.
• Stale context presented as current. If a page hasn't been updated in 30+ days, flag the staleness explicitly rather than presenting it as fresh.
• Modifying brain pages unprompted. The briefing is read-only by default. Do not create or update pages unless the user explicitly requests it.
• Ignoring coverage gaps. When a meeting participant has no brain page, say so. Silence about gaps hides ignorance.

Tools Used

• Search gbrain by name (query)
• Read a page from gbrain (get_page)
• List pages in gbrain by type (list_pages)
• Check gbrain health (get_health)
• View timeline entries in gbrain (get_timeline)
