What is claude-code-hooks CLAUDE.md?

Instructions for a Claude Code hook system that plays sounds when Claude Code events occur. Hooks are automated actions triggered by events such as starting or finishing a tool operation.

Use them to add or modify event sounds, hook scripts, configuration files, agent workflows, installation settings, or the project’s hook-count documentation.

They keep the hook configuration, sound mappings, installation files, documentation, and tests consistent when hooks are added or changed.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00898	$0.00898
Opus 5.5	$0.00359	$0.00359
Sonnet 5.5	$0.00180	$0.00180
Haiku 4.5	$0.00090	$0.00090

Security

Grade B, and why

claude-code-hooks CLAUDE.md scanned grade B with 1 finding 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 1mo 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Claude Code Hooks

Sound notification system for all 30 Claude Code hooks. Plays sound effects when hook events fire.

Critical: Hook Count Consistency

The hook count (currently 30) MUST match across ALL of these locations:

.claude/settings.json hook entries
install/settings-mac.json, settings-linux.json, settings-windows.json
hooks.py HOOK_SOUND_MAP keys + docstring count
hooks-config.json toggle count
HOOKS-README.md heading + numbered list
README.md badge + changelog table
presentation/index.html (slides 2, 3, TOC, totalSlides)
claude-code-test-agent.md frontmatter + body
demo/.claude/settings.json hook entries
demo/.claude/hooks/scripts/demo-hooks.py HOOK_SOUND_MAP + docstring
demo/hooks-lifecycle.html flowchart SVG + prompt cards + branding count

When adding a hook, use /workflows:workflow-add-hook — it updates all 14 files.

Agent Hooks

Only 6 of 30 hooks fire in agent sessions: PreToolUse, PostToolUse, PermissionRequest, PostToolUseFailure, Stop, SubagentStop. These are mapped in AGENT_HOOK_SOUND_MAP in hooks.py.

Workflows

/workflows:workflow-changelog [N] — Check last N versions for drift. Launches 2 agents in parallel, runs verification checklist, appends to changelog.md
/workflows:workflow-add-hook <HookName> — Add a new hook across all files (sounds, config, settings, scripts, docs, presentation)
/commit — Auto-generate commit message with timestamp and change count

Conventions

Hook names are PascalCase everywhere (e.g. PreToolUse, InstructionsLoaded)
Sound folder names are lowercase (e.g. pretooluse, instructionsloaded)
Settings files: timeout 5000 for all hooks except Setup (30000)
once: true only on: PreCompact, SessionStart, SessionEnd
async: true on all hooks
Changelog entries use PKT timezone: TZ=Asia/Karachi date
Version badge format: v2.X.X | Mon DD, YYYY HH:MM AM/PM PKT

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.
