Claude Code Plugins Directory is a marketplace containing plugins for Claude Code, including tools, commands, skills, agents, hooks, and model context servers. Claude Code users browse it to install Anthropic-maintained or approved third-party extensions.
Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00006 | $0.00547 |
| Opus 5.5 | $0.00002 | $0.00219 |
| Sonnet 5.5 | $0.00001 | $0.00109 |
| Haiku 4.5 | $0.00001 | $0.00055 |
Grade A, and why
list 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 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.
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.

What it actually says
List Hookify Rules
Load hookify:writing-rules skill first to understand rule format.
Show all configured hookify rules in the project.
Steps
-
Use Glob tool to find all hookify rule files:
pattern: ".claude/hookify.*.local.md" -
For each file found:
- Use Read tool to read the file
- Extract frontmatter fields: name, enabled, event, pattern
- Extract message preview (first 100 chars)
-
Present results in a table:
## Configured Hookify Rules
| Name | Enabled | Event | Pattern | File |
|------|---------|-------|---------|------|
| warn-dangerous-rm | ✅ Yes | bash | rm\s+-rf | hookify.dangerous-rm.local.md |
| warn-console-log | ✅ Yes | file | console\.log\( | hookify.console-log.local.md |
| check-tests | ❌ No | stop | .* | hookify.require-tests.local.md |
**Total**: 3 rules (2 enabled, 1 disabled)
- For each rule, show a brief preview:
### warn-dangerous-rm
**Event**: bash
**Pattern**: `rm\s+-rf`
**Message**: "⚠️ **Dangerous rm command detected!** This command could delete..."
**Status**: ✅ Active
**File**: .claude/hookify.dangerous-rm.local.md
- Add helpful footer:
---
To modify a rule: Edit the .local.md file directly
To disable a rule: Set `enabled: false` in frontmatter
To enable a rule: Set `enabled: true` in frontmatter
To delete a rule: Remove the .local.md file
To create a rule: Use `/hookify` command
**Remember**: Changes take effect immediately - no restart needed
If No Rules Found
If no hookify rules exist:
## No Hookify Rules Configured
You haven't created any hookify rules yet.
To get started:
1. Use `/hookify` to analyze conversation and create rules
2. Or manually create `.claude/hookify.my-rule.local.md` files
3. See `/hookify:help` for documentation
Example:
/hookify Warn me when I use console.log
Check `${CLAUDE_PLUGIN_ROOT}/examples/` for example rule files.
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.
