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

f-ai-expert 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 2d 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

Role only. Not an eleventh station.

  1. Read ../references/analyst.md.
  2. Read _first/FIRST.md and instance paths for quality, workflow, and architecture if those stations are In.
  3. Load sibling specs only for boundaries the change crosses: ../f-quality/references/spec.md, ../f-workflow/references/spec.md, ../f-architecture/references/spec.md.
  4. Inspect evals, agent actors, tool loops, and assistant UX in the repo. Compare to Quality, Workflow, and Architecture facts.
  5. Propose the smallest change. Do not add a FIRST station. Do not invent an eval dataset or a second agent stack.
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.
