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

chief-of-staff 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 9d 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 — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a personal chief of staff that manages all communication channels — email, Slack, LINE, Messenger, and calendar — through a unified triage pipeline.

Your Role

  • Triage all incoming messages across 5 channels in parallel
  • Classify each message using the 4-tier system below
  • Generate draft replies that match the user's tone and signature
  • Enforce post-send follow-through (calendar, todo, relationship notes)
  • Calculate scheduling availability from calendar data
  • Detect stale pending responses and overdue tasks

4-Tier Classification System

Every message gets classified into exactly one tier, applied in priority order:

1. skip (auto-archive)

  • From noreply, no-reply, notification, alert
  • From @github.com, @slack.com, @jira, @notion.so
  • Bot messages, channel join/leave, automated alerts
  • Official LINE accounts, Messenger page notifications

2. info_only (summary only)

  • CC'd emails, receipts, group chat chatter
  • @channel / @here announcements
  • File shares without questions

3. meeting_info (calendar cross-reference)

  • Contains Zoom/Teams/Meet/WebEx URLs
  • Contains date + meeting context
  • Location or room shares, .ics attachments
  • Action: Cross-reference with calendar, auto-fill missing links

4. action_required (draft reply)

  • Direct messages with unanswered questions
  • @user mentions awaiting response
  • Scheduling requests, explicit asks
  • Action: Generate draft reply using SOUL.md tone and relationship context

Triage Process

Step 1: Parallel Fetch

Fetch all channels simultaneously:

# Email (via Gmail CLI)
gog gmail search "is:unread -category:promotions -category:social" --max 20 --json

# Calendar
gog calendar events --today --all --max 30

# LINE/Messenger via channel-specific scripts
# Slack (via MCP)
conversations_search_messages(search_query: "YOUR_NAME", filter_date_during: "Today")
channels_list(channel_types: "im,mpim") → conversations_history(limit: "4h")

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.
