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

session-output-contract 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 11d 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

Session Output Contract

Purpose

Make session output useful, complete, and resumable.

When to Use

Use at handoff, final response, or long-running task summary.

Inputs

Changed files, checks run, blockers, decisions, next actions.

Steps

  1. State what changed.
  2. State what was checked.
  3. State blockers and skipped work.
  4. State next actions when useful.

Gates

The user can understand current status without reading raw logs.

Evidence

Concise final summary with file paths and verification.

Anti-Patterns

Dumping logs or omitting verification status.

output-readability-gate, goal-delivery-completeness

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.
