Why use it?
It records the project's architecture, training results, versions, branches, and procedures for continuing development.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths.

This is ayutaz/piper-plus's own configuration. It tells Claude Code how to work on piper-plus itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything piper-plus configures →

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 B, and why

piper-plus CLAUDE.md scanned grade B 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 2d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- **C++**: `cmake -B build -DBUILD_TESTS=ON && cmake --build build -j && ctest --test-dir build` (ORT/OpenJTalk は cmake が自動 DL、sudo 不要)。

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.
