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

aperture_lab_fstop 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 12d 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

Aperture Lab F-Stop

Use this skill when the goal is to operate F-Stop, the discovery and proposal subsystem inside Aperture Lab.

The canonical command surface is:

  • pnpm lab:fstop:campaign --provider <provider> --reviewer-provider <provider> --optimizer-provider <provider> ...
  • pnpm lab:fstop:run --provider <provider> --reviewer-provider <provider> --optimizer-provider <provider> ...
  • pnpm lab:fstop:review --reviewer-provider <provider> ...
  • pnpm lab:fstop:reviewer --provider <provider>
  • pnpm lab:fstop:propose --reviewer-provider <provider> --optimizer-provider <provider> ...
  • pnpm lab:fstop:optimize --provider <provider> ...
  • pnpm lab:fstop:optimizer --provider <provider>

Load first:

  • packages/lab/research/autoresearch-program.md
  • packages/lab/research/autoresearch-config.json

Main rule:

  • keep AI out of the live Aperture hot path
  • use F-Stop to discover, review, calibrate, and propose
  • let Aperture Lab own the scoring and gates
  • prefer lab:fstop:campaign for unattended VPS work

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.
