- Add systemPrompt to BeforeAgentStartEvent so extensions can see current prompt
- Change systemPromptAppend to systemPrompt in BeforeAgentStartEventResult for full replacement
- Extensions can now chain modifications (each sees the result of previous)
- Update ssh.ts to replace local cwd with remote cwd in system prompt
- Update pirate.ts, claude-rules.ts, preset.ts to use new API
fixes#575
When overriding a built-in tool (read, bash, edit, write, grep, find, ls)
without providing renderCall/renderResult, the built-in renderer is now
used automatically. This allows wrapping built-in tools for logging or
access control without reimplementing the UI (syntax highlighting, diffs, etc.).
- Add setActiveTools() to ExtensionAPI for dynamic tool management
- Extensions can now override, wrap, or disable built-in tools
- Add tool-override.ts example demonstrating the pattern
- Update documentation for tool override capabilities
When aborting a retry attempt, surface the retry-aware abort message
in the assistant output and tool results instead of a generic "Aborted".
- Set errorMessage for aborted streaming messages
- Render abort message without forcing a leading newline when no content
Three related fixes:
1. google-gemini-cli: Handle abort signal in stream reading loop
- Add abort event listener to cancel reader immediately when signal fires
- Fix AbortError detection in retry catch block (fetch throws AbortError,
not our custom message)
- Swallow reader.cancel() rejection to avoid unhandled promise
2. agent-session: Fix retry attempt counter showing 0 on cancel
- abortRetry() was resetting _retryAttempt before the catch block could
read it for the error message
3. interactive-mode: Restore main escape handler on agent_start
- When auto-retry starts, onEscape is replaced with retry-specific handler
- auto_retry_end (which restores it) fires on turn_end, after streaming begins
- Now restore immediately on agent_start if retry handler is still active
Amended: suppress reader.cancel() rejection on abort.
Add --no-tools flag that allows starting pi without any built-in tools,
enabling extension-only tool setups (e.g., pi-ssh-remote).
- Add --no-tools flag to CLI args parsing
- Handle --tools '' (empty string) as equivalent to no tools
- Fix system prompt to not show READ-ONLY mode when no tools (extensions may provide write capabilities)
- Add tests for new flag and system prompt behavior
fixes#555
Tools now use ExtensionRunner.createContext() instead of a separate
inline context factory. This ensures tools and event handlers share
the same context, fixing ctx.shutdown() and other context methods.
- Made ExtensionRunner.createContext() public
- Changed wrapRegisteredTools to accept ExtensionRunner instead of getContext callback
- Create ExtensionRunner when SDK custom tools are present (not just extensions)
- Removed redundant inline context factory from sdk.ts
The tool execution context was created with a no-op shutdown handler.
Now it delegates to ExtensionRunner.shutdown() which uses the handler
set by the mode via initialize().
Adds --no-extensions CLI flag that skips automatic extension discovery
while still allowing explicit -e paths. Three modes now available:
1. Default: auto-discover + any -e additions
2. --no-extensions: no extensions at all
3. --no-extensions -e foo.js: only load explicit extensions
Useful for debugging or running subagent instances without auto-discovered
extensions.
closes#524
Skip new version check at startup when set. Useful for Nix or other
package manager installs where npm install is not used.
Also documents PI_CODING_AGENT_DIR and other environment variables
in the README.

- Replace per-extension closures with shared ExtensionRuntime
- Split context actions: ExtensionContextActions (required) + ExtensionCommandContextActions (optional)
- Rename LoadedExtension to Extension, remove setter methods
- Change runner.initialize() from options object to positional params
- Derive hasUI from uiContext presence (no separate param)
- Add warning when extensions override built-in tools
- RPC and print modes now provide full command context actions
BREAKING CHANGE: Extension system types and initialization API changed.
See CHANGELOG.md for migration details.
