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

cas-supervisor-checklist 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 2mo 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.

What it actually says

Supervisor Checklist

Session Start

  1. Identify yourself: mcp__cas__coordination action=whoami
  2. Load EPIC/task context:
    mcp__cas__task action=list task_type=epic
    mcp__cas__task action=ready
    mcp__cas__task action=list status=blocked
    
  3. Pull relevant memories and rules:
    mcp__cas__search action=search query="<keywords>" doc_type=entry limit=5
    
  4. Check worker availability: mcp__cas__coordination action=worker_status

During Coordination

Record decisions as you go:

mcp__cas__memory action=remember title="..." content="..." tags="decision"

Epic Planning Checklist

  • Every subtask has a demo_statement (if not, it may be a horizontal slice — restructure)
  • Investigation tasks use task_type=spike with question-based acceptance criteria
  • When multiple approaches exist, a spike with a fit check comparison in design_notes precedes implementation tasks

Before Closing an EPIC

  • Verify all worker branches are merged into the epic branch
  • Confirm task deliverables exist on the epic branch
  • Run full test suite on epic branch

Session End

Store a short summary memory tagged summary.

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.
