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 | $0.00022 | $0.00955 |
| Opus 5 | $0.00011 | $0.00477 |
| Sonnet 5 | $0.00004 | $0.00191 |
| Haiku 4.5 | $0.00002 | $0.00096 |
Grade A, and why
claude-code-hook-agent 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 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.
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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the claude-code-hook-agent. Your goal is to trigger all 6 configured hooks (the only ones that actually fire in agent sessions) with sound playback. Follow ALL steps below in order.
Step-by-Step Workflow
Step 1: Read a file (triggers PreToolUse + PostToolUse)
Read the file .claude/agents/claude-code-hook-agent.md to confirm the hooks config.
Step 2: Web search (triggers PreToolUse + PostToolUse again)
Search the web for "current weather in Dubai UAE today" to get live weather data.
Step 3: Write a file (triggers PreToolUse + PostToolUse, may trigger PermissionRequest)
Write the weather results to tests-agents-hook/dubai-weather-report.txt.
Step 4: Run a bash command (triggers PreToolUse + PostToolUse, may trigger PermissionRequest)
Run: echo "Hook agent executed at $(date)"
Step 5: Intentionally read a non-existent file (triggers PostToolUseFailure)
Try to read tests-agents-hook/this-file-does-not-exist-12345.txt — this WILL fail and that is intentional to trigger the PostToolUseFailure hook.
Step 6: Fetch a URL (triggers PreToolUse + PostToolUse)
Fetch https://wttr.in/Dubai?format=3 to get a compact weather summary.
Hooks Configured (6 of 16 — only the ones that actually fire)
- PreToolUse — fires before every tool call (plays agent_pretooluse sound)
- PostToolUse — fires after every successful tool call (plays agent_posttooluse sound)
- PermissionRequest — fires when a tool needs user permission (plays agent_permissionrequest sound)
- PostToolUseFailure — fires after a failed tool call (plays agent_posttoolusefailure sound)
- Stop — fires when the agent session ends (plays agent_stop sound)
- SubagentStop — fires when a subagent completes (plays agent_subagentstop sound)
Output Format
After completing all steps, provide:
- Weather Report:
- Location: Dubai, UAE
- Temperature: [Celsius and Fahrenheit]
- Conditions: [description]
- Humidity: [percentage]
- Wind: [speed and direction]
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.

claude-code-hook-agent is an agent published in the GitHub repository shanraisshan/claude-code-hooks (531 stars, last pushed 3mo ago), licensed MIT. It adds 22 tokens to every session and 955 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
