anchor-test

anchor-test is a skill for Claude Code, Codex from unknowbug/anchorlaw. It costs 35 tokens per session (384 once invoked), scanned A, a copy of anchor.test, MIT.

A command-line workflow for running anchor verification and reporting each function’s health state.

In plain words
What is it for?
Use it after adding anchors or when investigating failed checks, with an optional verbose mode for a full error trace.
Why use it?
It shows whether recorded checks pass, have started failing, are outdated, or cannot run because the code does not compile independently.

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

anchor-test 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.

Origin

This is a copy

89% identical to anchor.test — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

anchor.test — 运行验证

Protocol: spec/protocol-v0.20.md §5.4 (Anchor Health States), §9 (Degraded Verification) Layer: L2 (Anchors) Execution: inline

触发场景

添加 anchor 后验证、CI 失败排查时。

操作步骤

  1. 运行(CLI,§14.4):anchorlaw test [module]-v 显示完整 traceback)。
  2. 按健康状态解读(§5.4):
    • healthy → 通过,声称已验证
    • degrading → 有测试失败:之前验证过的行为坏了 → 修复或更新 anchor,不得静默
    • unverified → 只有 idk:探索区,正常
    • stale_unknown → idk 超 90 天且函数改过(§5.3)→ 升级处理
    • uncompilable → 代码无法独立编译 → 按 §9 降级验证分类(Full/Partial/Degraded)处理,不硬跑
  3. 无法独立编译的代码先按 §9 分类模式,再决定能否运行。

输出

测试结果 + 每函数健康状态。

约束

  • 只通过 CLI 运行(§14.4)。
  • 失败不掩盖:degrading 如实报告。
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.
