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

weekly-prep-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 5d 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.

Weekly Prep Brief

Generate a single comprehensive weekly briefing that covers every external customer or prospect call in the next 7 days, with per-meeting account and contact research from Common Room.

Briefing Process

Step 1: Get the Week's External Meetings

Option A — Calendar connected: Use the ~~calendar connector to fetch all meetings scheduled in the next 7 days (or a user-specified range). Filter to keep only external meetings — those with attendees from outside your organization. Discard internal-only meetings, one-on-ones with colleagues, and recurring internal syncs.

Identify for each external meeting:

  • Company name
  • Meeting date and time
  • External attendee names and email addresses

Option B — No calendar connected: Ask the user: "To build your weekly prep brief, I'll need your upcoming external calls. Please list them: company name, date/time, and attendee names."

Accept freeform input and parse it into a structured list before proceeding.

Step 2: Confirm the Meeting List

Present the identified meetings to the user for confirmation before beginning research:

"Here are the external calls I found for this week. Let me know if anything's missing or should be excluded:

  • [Company] — [Day], [Time] — [Attendees]
  • ..."

This prevents wasted research on cancelled or incorrect meetings.

Step 3: Research Each Meeting

For each confirmed external meeting, run in parallel where possible:

  1. Account research — full account snapshot using the account-research skill
  2. Contact research — profile for each external attendee using the contact-research skill

Common Room data is the primary source. After CR research, run a quick recency check for each company — this is supplementary, not primary:

  • Search "[company name]" news scoped to the last 7 days
  • For executive attendees, search their name for recent public posts or interviews
  • Only include findings that are genuinely noteworthy (funding, leadership changes, major press). Don't pad the brief with generic news.

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.
