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

ceos-rocks 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 1mo 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.

ceos-rocks

Manage quarterly Rocks — the 3-7 most important priorities for the next 90 days. Each Rock has one owner, a measurable outcome, and a due date at quarter end.

When to Use

  • "Set rocks for this quarter" or "let's plan our quarterly priorities"
  • "Rock status" or "how are our rocks tracking?"
  • "Score rocks" or "end of quarter review"
  • "Create a rock" or "add a new rock for [person]"
  • "What rocks does [person] own?"
  • Any quarterly planning or review conversation

Context

Finding the CEOS Repository

Search upward from the current directory for the .ceos marker file. This file marks the root of the CEOS repository.

If .ceos is not found, stop and tell the user: "Not in a CEOS repository. Clone your CEOS repo and run setup.sh first."

Sync before use: Once you find the CEOS root, run git -C <ceos_root> pull --ff-only --quiet 2>/dev/null to get the latest data from teammates. If it fails (conflict or offline), continue silently with local data.

Key Files

File Purpose
data/rocks/QUARTER/ Rock files for each quarter (e.g., data/rocks/2026-Q1/)
data/vision.md V/TO document (1-Year Plan for alignment checks)
templates/rock.md Template for creating new Rock files
data/accountability.md Accountability Chart (seat owners for Rock-owner alignment)

Rock File Format

Each Rock is a markdown file with YAML frontmatter:

id: rock-001
title: "Launch Beta Program"
owner: "brad"
quarter: "2026-Q1"
status: on_track       # on_track | off_track | complete | dropped
created: "2026-01-02"
due: "2026-03-31"

Status values:

  • on_track — progressing as expected
  • off_track — behind or at risk
  • complete — done (set during end-of-quarter scoring)
  • dropped — no longer a priority (set during end-of-quarter scoring)

File naming: rock-NNN-slug.md where NNN is a zero-padded ID and slug is the title slugified (lowercase, hyphens, no special chars).

Milestones: Rocks support two milestone formats:

  • Structured (frontmatter): Array of milestone objects with title, optional due date, and status (todo/in_progress/done). Enables date-based progress tracking and overdue detection.
  • Markdown checklist (body): Traditional - [ ] / - [x] checklist items in the Milestones section. Simple and human-friendly.

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.
