aishield: Instructions file for Claude Code

CLAUDE.md

aishield CLAUDE.md is an instructions file for Claude Code from lm203688/aishield. It costs 288 tokens per session, scanned A, original, MIT.

A short instruction file for AI coding agents working on AIShield, a local security scanner. It lists rules about safe scanning, private data, accurate rule counts, and the commands used to verify changes.

In plain words
What is it for?
Use it to start work on AIShield, run its test suite, verify scanning isolation, and follow the project's local development routine.
Why use it?
It gives the agent critical constraints before it edits the repository, including not running commands found in scanned content. It also reduces mistakes caused by outdated documentation or incomplete checks.

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is lm203688/aishield's own configuration. It tells Claude Code how to work on aishield 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 aishield 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.

Opus 5.5 $0.00115 $0.00115

Security

Grade A, and why

aishield 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 16d 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.

What it actually says

CLAUDE.md

Agent 原生项目手册见 AGENTS.md —— 架构、核心不变量、贡献约定（含范围纪律）都在那里。

硬不变量（违背即 bug，先读再动）

  1. 扫描器绝不 spawn 被扫配置里的命令 —— 被扫内容只当字符串读取、做正则/语义匹配。 自证：python scripts/prove_isolation.py
  2. 代码与配置绝不上传云端 —— 本地优先、零依赖、可离线。
  3. 勿引用过期规则计数（227/215/133/228）。真值看 /api/v1/health 的 rules_breakdown； 当前 256 = 静态 286 + 情报 8 + 雷达 19。
  4. 本地绿 ≠ CI 绿；多文件推送走 scripts/_push_batch.py，推完 API 复验。

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.
