Custom hook creation for preventing unwanted behaviors in Claude Code. Triggers: hook, hookify, rule, block, warn, prevent, pattern, detect, unwanted behavior, dangerous command, coding standards
/plugin marketplace add thkt/claude-config/plugin install complete-workflow-system@thkt-development-workflowsThis skill is limited to using the following tools:
EVALUATIONS.mdCreate declarative rules to block dangerous operations or warn about potential issues.
---
name: rule-name
enabled: true
event: file|bash|stop|prompt|all
pattern: regex-pattern # simple rules
action: warn|block
conditions: # complex rules (optional)
- field: file_path|new_text|command|user_prompt
operator: regex_match|contains|not_contains
pattern: pattern-to-match
---
Message shown when pattern matches (supports **Markdown**).
| Event | When Triggered | Use Case |
|---|---|---|
file | Edit/Write | Code patterns, debug code |
bash | Bash commands | Dangerous commands |
stop | Claude stops | Require tests before done |
prompt | User message | Input validation |
| Action | Behavior | Exit Code |
|---|---|---|
warn | Show message, continue | 0 |
block | Show message, stop | 2 |
| Event | Fields |
|---|---|
| file | file_path, new_text, old_text, content |
| bash | command |
| prompt | user_prompt |
| stop | transcript |
| Pattern | Matches |
|---|---|
rm\s+-rf | rm -rf commands |
console\.log\( | console.log statements |
\.env$ | .env files |
chmod\s+777 | chmod 777 |
| Location | Scope |
|---|---|
.claude/hookify.*.local.md | Project |
~/.claude/hookify.*.local.md | Global |
Commands: /hookify [desc], /hookify:list, /hookify:configure
Start with warn, upgrade to block if needed. Use specific patterns to avoid false positives.
/hookify, /hookify:list, /hookify:configurereviewing-security (detect dangerous patterns)This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.
This skill should be used when the user asks to "create an agent", "add an agent", "write a subagent", "agent frontmatter", "when to use description", "agent examples", "agent tools", "agent colors", "autonomous agent", or needs guidance on agent structure, system prompts, triggering conditions, or agent development best practices for Claude Code plugins.
This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.
