Extended the Kitty protocol parser to handle functional keys with
~ terminator (Delete, Insert, PageUp, PageDown) and Home/End keys.
Updated editor.ts and input.ts to use the new helpers.
Exports getAvailableModels, getApiKeyForModel, findModel, login, logout,
and getOAuthProviders from @mariozechner/pi-coding-agent so scripts using
AgentSession directly can reuse OAuth token storage and model resolution.
Fixes#245
Backspace, Delete, and arrow keys now use Intl.Segmenter to operate
on grapheme clusters instead of individual UTF-16 code units. This
fixes deletion of emojis and other multi-codepoint characters.
fixes#240
Fixes keyboard input in Ghostty on Linux when Num Lock is enabled.
The Kitty protocol includes Caps Lock (64) and Num Lock (128) bits
in modifier values. Now masks out lock bits when matching shortcuts.
Added helper functions: isArrowUp/Down/Left/Right, isEnter, isTab,
isBackspace, isShiftEnter, isAltEnter, isAltLeft/Right, isCtrlLeft/Right
fixes#243
- Add supportsXhigh() function to ai package for checking xhigh support
- Clamp xhigh to high for OpenAI models that don't support it
- Update coding-agent to use centralized supportsXhigh()
- gpt-5.2, gpt-5.2-codex now show xhigh in thinking selector
Closes#236
- Add XHIGH_MODELS constant and getAvailableThinkingLevels() to AgentSession
- Update ThinkingSelectorComponent to accept availableLevels parameter
- Both shift+tab cycling and /thinking command now show xhigh for supported models
- Update types.ts documentation to list supported models
When cwd is `~/.pi/agent/` or a subdirectory, the global AGENTS.md file
was included twice in the system prompt.
`loadProjectContextFiles()` loads context files in two steps:
1. Explicitly loads from `getAgentDir()` (`~/.pi/agent/`)
2. Walks from cwd up to root, collecting all AGENTS.md/CLAUDE.md files
There was no deduplication. When cwd is at or below `~/.pi/agent/`, the
ancestor walk includes that directory again.
Fix: track seen paths with a Set and skip duplicates.
- Export getMarkdownTheme() from coding-agent for custom tools
- Chain/parallel modes now use Markdown component in expanded view
- Chain streaming updates include all previous steps (not just current)
- Strip {previous} placeholder from task preview in renderCall
Breaking changes:
- Custom tools now require index.ts entry point in subdirectory
(e.g., tools/mytool/index.ts instead of tools/mytool.ts)
Subagent tool improvements:
- Refactored to use Message[] from ai package instead of custom types
- Extracted agent discovery to separate agents.ts module
- Added parallel mode streaming (shows progress from all tasks)
- Added turn count to usage stats footer
- Removed redundant Query section from scout output
Fixes:
- JSON mode stdout flush: Fixed race condition where pi --mode json
could exit before all output was written, causing consumers to
miss final events
Also:
- Added signal/timeout support to pi.exec() for custom tools and hooks
- Renamed pi-pods bin to avoid conflict with pi
Add isEscape() helper that handles both raw (\x1b) and Kitty protocol
(\x1b[27u) Escape sequences. Update all components that check for
Escape key to use the new helper.
Add getApiKey hook to AgentLoopConfig that resolves API keys dynamically
before each LLM call. This allows short-lived OAuth tokens (e.g. GitHub
Copilot, Anthropic OAuth) to be refreshed between turns when tool
execution takes a long time.
Previously, the API key was resolved once when ProviderTransport.run()
was called and passed as a static string to the agent loop. If the loop
ran for longer than the token lifetime (e.g. 30 minutes for Copilot),
subsequent LLM calls would fail with expired token errors.
Changes:
- Add getApiKey hook to AgentLoopConfig (packages/ai)
- Call getApiKey before each LLM call in streamAssistantResponse
- Update ProviderTransport to pass getApiKey instead of static apiKey
- Update web-ui ProviderTransport with same pattern
- Export isBashToolResult, isReadToolResult, etc. type guards
- Update hooks.md with type guard usage examples
- Document custom tool handling in hooks.md
Breaking change: ToolResultEvent now exposes content and typed details
instead of just a result string. Hook handlers returning { result: ... }
must change to { content: [...] }.
- ToolResultEvent is now a discriminated union based on toolName
- Each built-in tool has typed details (BashToolDetails, etc.)
- Export tool details types and TruncationResult
- Update hooks.md documentation
Closes#233
Implement Agent Skills standard (https://agentskills.io/specification):
- Validate name (must match parent dir, lowercase, max 64 chars)
- Validate description (required, max 1024 chars)
- Warn on unknown frontmatter fields
- Warn on name collisions (keep first)
- Change prompt format to XML structure
- Remove {baseDir} placeholder (use relative paths)
- Add tests and update documentation
fixes#231
These generic helpers aren't used externally and would require
exporting MODIFIERS constants to be ergonomic. The specific
isCtrl* helpers cover all practical use cases.
- Add isCtrlD helper to keys.ts
- CustomEditor intercepts Ctrl+D and only triggers callback when editor is empty
- Single Ctrl+D with empty input exits immediately
- Update CHANGELOG to frame as feature (Kitty protocol support) not fix
- Add isCtrlA/C/E/K/O/P/T/U/W helper functions that check both raw and Kitty formats
- Add isAltBackspace helper function
- Refactor editor.ts, input.ts, select-list.ts to use helper functions
- Refactor custom-editor.ts, session-selector.ts, user-message-selector.ts
- Add CHANGELOG entry for the Shift+Enter fix
Enable the Kitty keyboard protocol on terminal start to receive enhanced
key sequences that include modifier information. This fixes Shift+Enter
not working in Ghostty, Kitty, WezTerm, and other modern terminals.
Changes:
- Enable Kitty protocol on start (\x1b[>1u), disable on stop (\x1b[<u)
- Add centralized key definitions in packages/tui/src/keys.ts
- Support both legacy and Kitty sequences for all modifier+key combos:
- Shift+Enter, Alt+Enter for newlines
- Shift+Tab for thinking level cycling
- Ctrl+C, Ctrl+A, Ctrl+E, Ctrl+K, Ctrl+U, Ctrl+W, Ctrl+O, Ctrl+P, Ctrl+T
- Alt+Backspace for word deletion
- Export Keys constants and helper functions from @mariozechner/pi-tui
