Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00043 | $0.03253 |
| Opus 5 | $0.00022 | $0.01626 |
| Sonnet 5 | $0.00009 | $0.00651 |
| Haiku 4.5 | $0.00004 | $0.00325 |
Grade B, and why
hooks-and-enforcement scanned grade B with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
if echo "$COMMAND" | grep -qE "(rm -rf /|sudo|chmod 777|curl.*\| bash)"; then Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Recursive force deletemediumDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
if echo "$COMMAND" | grep -qE "(rm -rf /|sudo|chmod 777|curl.*\| bash)"; then Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Hooks and Enforcement
Overview
Lifecycle hooks are the mechanism for enforcing rules that an AI agent must follow without exception. While CLAUDE.md instructions guide behavior, they are suggestions the agent can interpret loosely or skip. Hooks are enforcement -- they run automatically at defined points in the agent's lifecycle and block progress when checks fail.
Core principle: Instructions in CLAUDE.md are suggestions; hooks are enforcement. Use hooks for anything that MUST happen.
Dependency: Claude Code with settings.json hook configuration. Security scanning tools (e.g., Semgrep) for code analysis hooks.
When to Use
- When you need linting, tests, or compilation to pass before every commit
- When agent-generated code must be scanned for security vulnerabilities before shipping
- When you need an audit trail of every shell command the agent runs
- When you want automated approval of safe permission prompts to reduce friction
- When you have tests or files the agent must never modify
When NOT to Use
- For stylistic preferences or soft guidelines (put those in CLAUDE.md)
- For checks that are slow and disruptive when run on every edit (use pre-commit instead)
- When the project has no CI/CD and no quality requirements
Common Mistakes
| Mistake | Why it's wrong |
|---|---|
| Putting critical rules only in CLAUDE.md | CLAUDE.md is advisory. The agent can misinterpret or skip instructions. Hooks enforce mechanically -- they cannot be bypassed. |
| Using per-edit hooks for slow operations like full test suites | Per-edit hooks fire constantly and destroy flow. Sid: pre-commit hooks are preferred because they are "less disruptive to flow." Reserve per-edit for fast checks only. |
| Letting the agent modify its own test files | The agent will "fix" failing tests by weakening assertions. Create immutable test files the agent cannot touch. Josh: "Create immutable tests the agent cannot modify." |
| Skipping audit logging for agent sessions | Without an audit trail you cannot debug what went wrong. Log every shell command with timestamp. Milan: "You need to know what the agent did and when." |
| Running security scans only in CI | Agent-generated code can introduce vulnerabilities locally before it ever reaches CI. Scan before commit so vulnerabilities never enter the repo. |
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.

hooks-and-enforcement is a skill published in the GitHub repository mlopscommunity/Coding-Agents-Conference-skills (37 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 43 tokens to every session and 3,253 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 3 findings (asks for root, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
