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

prospec AGENTS.md 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 yesterday.

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.

Tech Stack

  • Language: typescript
  • Package Manager: pnpm

Language Policy

The user's primary language for change artifacts (.prospec/changes/**, .prospec/archive/**, .prospec/abandoned/**, prospec/specs/_archived-history/**) is Traditional Chinese (Taiwan), and requests may be phrased in it. The trust zone (prospec/CONSTITUTION.md, prospec/README.md, prospec/index.md, prospec/specs/product.md, prospec/specs/features/**, prospec/ai-knowledge/**) always remains in English, as do code, identifiers, technical terms, and git commit messages — it is technical documentation read next to the code and cited in English, exempt from the Traditional Chinese (Taiwan) requirement. The Constitution's Language Policy rule is generated from this same path set and names the few per-spot exceptions in both directions — trust-zone spots that may use Traditional Chinese (Taiwan), and change-artifact spots that stay English because their content is copied into the trust zone verbatim.

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.
