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 | $0.00044 | $0.00679 |
| Opus 5.5 | $0.00018 | $0.00272 |
| Sonnet 5.5 | $0.00009 | $0.00136 |
| Haiku 4.5 | $0.00004 | $0.00068 |
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 23d 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 — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
List Hookify Rules
Load hookify-plus:writing-rules skill first to understand rule format.
Display all hookify rules the engine loads.
Steps
-
Find rule files in all three locations the engine scans:
.claude/hookify-plus/*.md(project)~/.claude/hookify-plus/*.md(global)~/.claude/plugins/cache/<marketplace>/<plugin>/<version>/hookify-plus/*.md(sibling plugins, but only the marketplace hookify-plus itself is installed in, and only version dirs with an.in_usemarker). Find that marketplace dir by looking under~/.claude/plugins/cache/for the one that contains ahookify-plus/subdirectory.
-
For each file found:
- Read the file with the Read tool.
- 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 | dangerous-rm.md |
| warn-console-log | ✅ Yes | file | console\.log\( | console-log.md |
| check-tests | ❌ No | stop | .* | require-tests.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-plus/dangerous-rm.md
- Add helpful footer:
---
To modify a rule: Edit the `.md` file in `.claude/hookify-plus/` 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 `.md` file from `.claude/hookify-plus/`
To create a rule: Use `/hookify` command
**Remember**: Changes take effect immediately - no restart needed
If No Rules Found
If no hookify rules exist, display:
## No Hookify Rules Configured
No hookify rules created yet.
To get started:
1. Use `/hookify` to analyze conversation and create rules
2. Or manually create `.claude/hookify-plus/my-rule.md` files
3. See `/hookify-plus:help` for documentation
Example:
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.

list is a skill published in the GitHub repository anthony-spruyt/claude-plugins (2 stars, last pushed today), licensed MIT. It adds 44 tokens to every session and 679 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
