Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00078 | $0.04172 |
| Opus 5 | $0.00039 | $0.02086 |
| Sonnet 5 | $0.00016 | $0.00834 |
| Haiku 4.5 | $0.00008 | $0.00417 |
Grade A, and why
eval-hooks scanned grade A with 2 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 3d 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.
Reads agent configuration directorieslowAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
| `~/.claude/settings.json` | Global user | No | Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Flag any PreToolUse script that contains slow operations (`curl`, `sleep`, network calls) without a surrounding timeout guard. How it starts
The opening of the file, as written. The whole thing — 353 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hooks Evaluator
Discover all Claude Code hooks across every settings file in scope, validate each one against the filesystem and hook semantics, then run an interactive session to confirm or improve them.
The goal is not just to score; it is to leave every hook working, correctly scoped, and safe to run.
When to Use
- First time adding hooks (validate before committing)
- A hook never fires, or fires on every tool call
- The agent hangs noticeably before executing a tool
- A PreToolUse hook is supposed to block but doesn't
- After copying hooks from another project or machine
- Periodic hygiene: "are all these hooks still doing something useful?"
Key Concepts
Event types
| Event | When it fires | Can block? (exit 2) |
|---|---|---|
PreToolUse |
Before any tool call | Yes |
PermissionRequest |
When a permission dialog appears | Yes |
PostToolUse |
After tool completes successfully | No (shows stderr to Claude) |
PostToolUseFailure |
After a tool fails | No |
PostToolBatch |
After a full batch of parallel tool calls resolves | Yes (stops agentic loop) |
UserPromptSubmit |
When user submits a prompt | Yes |
UserPromptExpansion |
When a slash command expands | Yes |
Stop |
When Claude finishes responding | Yes (continues the turn) |
SubagentStop |
When a subagent finishes | Yes (continues the subagent) |
TeammateIdle |
When an agent team teammate goes idle | Yes |
TaskCreated |
When a task is being created | Yes |
TaskCompleted |
When a task is being marked as completed | Yes |
PreCompact |
Before context compaction | Yes |
ConfigChange |
When a configuration file changes | Yes (except policy_settings) |
PermissionDenied |
When auto-mode classifier denies a tool call | No |
SessionStart |
When a session starts or resumes | No |
Setup |
On --init-only or -p --init/--maintenance | No |
StopFailure |
When the turn ends due to API error | No |
Notification |
When Claude sends a notification | No |
MessageDisplay |
While assistant message streams | No |
SubagentStart |
When a subagent is spawned | No |
InstructionsLoaded |
When a CLAUDE.md or rules file is loaded | No |
CwdChanged |
When working directory changes | No |
FileChanged |
When a watched file changes on disk | No |
WorktreeCreate |
When a worktree is created (replaces default git behavior) | Yes (any non-zero fails) |
WorktreeRemove |
When a worktree is removed | No |
PostCompact |
After compaction completes | No |
SessionEnd |
When a session terminates | No |
ElicitationResult |
After user responds to MCP elicitation | Yes |
Elicitation |
When MCP server requests user input | Yes |
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.

eval-hooks is a skill published in the GitHub repository FlorianBruniaux/claude-code-plugins (40 stars, last pushed 3mo ago), licensed MIT. It adds 78 tokens to every session and 4,172 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
