enforce-hooks

enforce-hooks is a skill for Claude Code from Bande-a-Bonnot/Boucle-framework. It costs 86 tokens per session (1,048 once invoked), scanned A, original, MIT.

A skill that reads a CLAUDE.md file and turns selected tagged rules into automatic checks before covered Claude Code tool calls.

In plain words
What is it for?
Use it to scan project rules, install dynamic enforcement hooks, and verify them with smoke tests. The dynamic mode rereads CLAUDE.md whenever a tool is used.
Why use it?
It reduces reliance on an AI agent remembering project instructions by checking enforceable rules at runtime.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

  • high Tool Misuse · line 91
    Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.
    Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.
  • low Supply Chain · line 91
    Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.
    Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.

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

enforce-hooks 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 2mo ago.

The scan reads SKILL.md. This mod also ships 12 executable files (enforce-hooks.py, engine.sh, examples/enforce-knowledge-first.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Enforce Hooks

Turn CLAUDE.md rules into runtime checks for covered Claude Code tool calls.

When to use

  • User says "enforce my CLAUDE.md rules" or "generate hooks from my CLAUDE.md"
  • User complains about Claude ignoring CLAUDE.md instructions
  • User wants code-level checks for project rules
  • User mentions @enforced directives

Default workflow

Use dynamic plugin mode unless the user explicitly asks for individual generated hook scripts.

  1. Read the user's CLAUDE.md, or the file they specify.
  2. Run python3 tools/enforce/enforce-hooks.py --scan from a local checkout, or download enforce-hooks.py and run python3 enforce-hooks.py --scan.
  3. Explain which rules are enforceable, which are skipped, and why.
  4. With the user's confirmation, run python3 enforce-hooks.py --install-plugin.
  5. Verify with python3 .claude/hooks/enforce-hooks.py --verify and python3 .claude/hooks/enforce-hooks.py --smoke-test.
  6. Tell the user to start a fresh Claude Code session from the same project root.

Plugin mode installs one PreToolUse wrapper plus the Python engine in .claude/hooks/. It reads CLAUDE.md on every tool call, so rule changes do not require regenerating scripts.

What is enforceable

A directive is enforceable when the tool call itself contains enough signal to decide before execution.

Enforceable examples:

  • "Never modify .env files" -> file-guard rule for Write/Edit/MultiEdit paths
  • "Don't force push" -> bash-guard rule for push --force and push -f
  • "Always search locally before using web search" -> require-prior-tool rule
  • "Don't commit to main" -> branch-guard rule for protected branches
  • "Never run rm -rf" -> bash-guard rule for dangerous command patterns
  • "Don't edit files in vendor/" -> file-guard path rule
  • "Always run tests before committing" -> require-prior-tool or command rule
  • "Never use sudo" -> bash-guard rule
  • "Don't read files in secrets/" -> file-guard rule including Read
  • "Use TypeScript, not JavaScript" -> content or path rule for generated files

What ships with it

15 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
