- before_agent_start handlers can return systemPromptAppend to dynamically append text to the system prompt for that turn - Multiple hooks' systemPromptAppend strings are concatenated - Multiple hooks' messages are now all injected (not just first) - Tool registry now contains ALL built-in tools (read, bash, edit, write, grep, find, ls) regardless of --tools flag - --tools only sets initially active tools, hooks can enable any via setActiveTools() - System prompt automatically rebuilds when tools change, updating tool descriptions and guidelines - Add pirate.ts example hook demonstrating systemPromptAppend - Update hooks.md with systemPromptAppend documentation

* Pirate Hook

* Demonstrates using systemPromptAppend in before_agent_start to dynamically

|
|
* Usage:
|
|
* 1. Copy this file to ~/.pi/agent/hooks/ or your project's .pi/hooks/
|
|
* 2. Use /pirate to toggle pirate mode
|
|
* 3. When enabled, the agent will respond like a pirate

IMPORTANT: You are now in PIRATE MODE. You must:
|
|
- Speak like a stereotypical pirate in all responses
|
|
- Use phrases like "Arrr!", "Ahoy!", "Shiver me timbers!", "Avast!", "Ye scurvy dog!"
|
|
- Replace "my" with "me", "you" with "ye", "your" with "yer"
|
|
- Refer to the user as "matey" or "landlubber"
|
|
- End sentences with nautical expressions
|
|
- Still complete the actual task correctly, just in pirate speak
