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

turritopsis-onboarding 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.

How it starts

The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Turritopsis Onboarding

Use the installed Agent as the classifier and writer. Keep scanning local and deterministic; never require a second model or API key for onboarding.

Cold start

  1. Run turritopsis scan. Reuse existing scan-evidence.json unless the repository changed enough to justify --refresh.
  2. Read scan-run.json first, then inspect coverage and omitted materials in scan-evidence.json. Do not assume the snapshot contains everything.
  3. Read stage-types.md. Select one responsibility for each Stage.
  4. Read project-suites.md. Choose the smallest suitable suite; combine suites for hybrids.
  5. Inspect only the evidence needed to classify durable knowledge regions. Do not generate one Stage per file, directory, or document.
  6. Read cli-contract.md, then write skeleton.json from that public contract. Never inspect installed package source to discover fields, revisions, or write calls.
  7. Run turritopsis apply-skeleton skeleton.json. Fix every validation error instead of bypassing it.
  8. Run turritopsis get-stage --all, write the Stage body files and one batch manifest, then use turritopsis update-stages --manifest updates.json --actor <name>.

Use paired-examples.md when a Stage is structurally valid but vague. Use the seven fixtures when selecting a suite:

Fixtures are examples, not templates. Replace their fictional evidence paths and choose only the types the target project needs.

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.
