What is prospec CLAUDE.md?

Repository instructions for Prospec, a TypeScript project that uses structured specifications and an AI knowledge base to guide development. They define which project documents use English and which use Traditional Chinese for Taiwan.

Use them when editing Prospec code, specifications, change records, archived material, or its AI knowledge documentation.

They prevent changes from violating the project's documentation language policy or its technical conventions. They also point agents to the project's constitution and specification resources.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01308	$0.01308
Opus 5.5	$0.00523	$0.00523
Sonnet 5.5	$0.00262	$0.00262
Haiku 4.5	$0.00131	$0.00131

Security

Grade A, and why

prospec CLAUDE.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 9d 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.

The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

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.
