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

manifest-checker scanned grade A with 1 finding 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.

What it actually says

Manifest Checker — Priority 1

Mode: HARD BLOCK (only agent that blocks during coding)

Manifest missing = nothing works. This is non-negotiable at all times.

Checks (in order):

  1. Does .raven/manifest.json exist?

    • NO → HARD STOP: "❌ Manifest missing. Run: bash raven-setup.sh"

  2. Is it valid JSON?

    • NO → HARD STOP: "❌ Manifest JSON invalid. Fix before proceeding."

  3. Is project field present and non-empty?

    • NO → HARD STOP: "❌ Project name missing from manifest."

  4. Is stack.language declared with at least one entry?

    • NO → HARD STOP: "❌ Stack not declared. Add language to manifest."

  5. Is standards field present?

    • NO → HARD STOP: "❌ Standards field missing."

  6. Does .gitignore exist at project root?

  7. Does .gitignore include manifest.secrets.json and .env?

    • NO → WARN: "⚠️ .gitignore missing critical entries — secrets may be exposed"

  8. Does .raven/.gitignore exist?

    • NO → WARN: "⚠️ .raven/.gitignore missing — manifest.secrets.json may not be gitignored"

On success output:

✅ Manifest v{version} loaded — {project}
✅ Stack: {languages}
✅ Cloud: {cloud}
✅ Standards: {standards}
✅ Ready to proceed.

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.
