  • Custom tools with session lifecycle, examples for hooks and tools 
    - Custom tools: TypeScript modules that extend pi with new tools
  - Custom TUI rendering via renderCall/renderResult
  - User interaction via pi.ui (select, confirm, input, notify)
  - Session lifecycle via onSession callback for state reconstruction
  - Examples: todo.ts, question.ts, hello.ts

- Hook examples: permission-gate, git-checkpoint, protected-paths

- Session lifecycle centralized in AgentSession
  - Works across all modes (interactive, print, RPC)
  - Unified session event for hooks (replaces session_start/session_switch)

- Box component added to pi-tui

- Examples bundled in npm and binary releases

  • Fix image limits test to use realistic payload sizes 
    Previous test used compressed 8k images (0.01MB) which was meaningless.
Now tests with actual large noise images that don't compress.

Realistic payload limits discovered:
- Anthropic: 6 x 3MB = ~18MB total (not 32MB as documented)
- OpenAI: 2 x 15MB = ~30MB total
- Gemini: 10 x 20MB = ~200MB total (very permissive)
- Mistral: 4 x 10MB = ~40MB total
- xAI: 1 x 20MB (strict request size limit)
- Groq: 5 x 5760px images (5 image + pixel limit)
- zAI: 2 x 15MB = ~30MB (50MB request limit)
- OpenRouter: 2 x 5MB = ~10MB total

Also fixed GEMINI_API_KEY env var (was GOOGLE_API_KEY).

  • GitHub Copilot: auto-enable models, fix gpt-5 API, normalize tool call IDs 
    - Auto-enable all models after /login via POST /models/{model}/policy
- Use openai-responses API for gpt-5/o3/o4 models (not accessible via completions)
- Normalize tool call IDs when switching between github-copilot models with different APIs
  (fixes #198: openai-responses generates 450+ char IDs with special chars that break other models)
- Update README with streamlined GitHub Copilot docs

  • feat: initial impl 
    - add GitHub Copilot model discovery (env token fallback, headers,
compat) plus fallback list and quoted provider keys in generated map
- surface Copilot provider end-to-end (KnownProvider/default, env+OAuth
token refresh/save, enterprise base URL swap, available only when
creds/env exist)
- tweak interactive OAuth UI to render instruction text and prompt
placeholders

gpt-5.2-high took about 35 minutes. It had a lot of trouble with `npm
check`  and went off on a "let's adjust every tsconfig" side quest.
Device code flow works, but the ai/scripts/generate-models.ts impl is
wrong as models from months ago are missing and only those deprecated
are accessible in the /models picker.

  • Fix image rendering artifacts and improve show-images selector 
    - Image component returns correct number of lines (rows) for TUI accounting
- Empty lines rendered first, then cursor moves up and image is drawn
- This clears the space the image occupies before rendering
- Add spacer before inline images in tool output
- Create ShowImagesSelectorComponent with borders like other selectors
- Use showSelector pattern for /show-images command

  • mom: refactor to use AgentSession for context management

- Create MomSessionManager for channel-based context.jsonl storage
- Create MomSettingsManager for mom-specific settings

- Split logging: tool results go to context.jsonl, human messages to log.jsonl
- Enable auto-compaction and overflow detection from coding-agent

  • Auto-retry on transient provider errors (overloaded, rate limit, 5xx) 
    - Add retry logic with exponential backoff (2s, 4s, 8s) in AgentSession
- Disable Anthropic SDK built-in retries (maxRetries: 0) to allow app-level handling
- TUI shows retry status with Escape to cancel
- RPC mode: add set_auto_retry, abort_retry commands and auto_retry_start/end events
- Configurable via settings.json: retry.enabled, retry.maxRetries, retry.baseDelayMs
- Exclude context overflow errors from retry (handled by compaction)

  • fixes #161: stop theme watcher and exit cleanly in print mode 
    The theme file watcher was keeping the Node.js process alive indefinitely
even in print mode where hot-reload is unnecessary. This simple fix calls
stopThemeWatcher() and process.exit(0) after print mode completes.

- Added stopThemeWatcher() call after runPrintMode() completes
- Added process.exit(0) to ensure clean process termination
- Imported stopThemeWatcher from theme module

This is a minimal fix that addresses the symptom (process hanging) without
changing the theme initialization logic.

  • fixes #161: disable theme watcher in print mode 
    The theme file watcher was keeping the Node.js process alive indefinitely
even in print mode where hot-reload is unnecessary. This fix adds an
enableWatcher parameter to initTheme() and setTheme() functions, and only
enables watchers in interactive mode.

- Modified initTheme() to accept enableWatcher parameter (default: false)
- Modified setTheme() to accept enableWatcher parameter (default: false)
- Updated main.ts to only enable watchers in interactive mode
- Updated InteractiveMode to enable watchers when changing themes

  • Add Mistral as AI provider 
    - Add Mistral to KnownProvider type and model generation
- Implement Mistral-specific compat handling in openai-completions:
  - requiresToolResultName: tool results need name field
  - requiresAssistantAfterToolResult: synthetic assistant message between tool/user
  - requiresThinkingAsText: thinking blocks as <thinking> text
  - requiresMistralToolIds: tool IDs must be exactly 9 alphanumeric chars
- Add MISTRAL_API_KEY environment variable support
- Add Mistral tests across all test files
- Update documentation (README, CHANGELOG) for both ai and coding-agent packages
- Remove client IDs from gemini.md, reference upstream source instead

  • Add hooks system with pi.send() for external message injection 
    - Hook discovery from ~/.pi/agent/hooks/, .pi/hooks/, --hook flag
- Events: session_start, session_switch, agent_start/end, turn_start/end, tool_call, tool_result, branch
- tool_call can block execution, tool_result can modify results
- pi.send(text, attachments?) to inject messages from external sources
- UI primitives: ctx.ui.select/confirm/input/notify
- Context: ctx.exec(), ctx.cwd, ctx.sessionFile, ctx.hasUI
- Docs shipped with npm package and binary builds
- System prompt references docs folder

  • feat(coding-agent): implement hooks system 
    - Add hooks infrastructure in core/hooks/ (loader, runner, types)
- HookUIContext interface with mode-specific implementations
- Interactive mode: TUI-based selector/input/confirm dialogs
- RPC mode: JSON protocol for hook UI requests/responses
- Print mode: no-op UI context (hooks run but can't prompt)
- AgentSession.branch() now async, returns { selectedText, skipped }
- Settings: hooks[] and hookTimeout configuration
- Export hook types from package for hook authors

Based on PR #147 proposal, adapted for new architecture.

- Remove proactive mid-turn compaction abort
- Merge turn prefix summary into main summary
- Add isCompacting property to AgentSession and RPC state
- Block input during compaction in interactive mode
- Show compaction count on session resume

  • feat(coding-agent): implement new compaction system with overflow recovery 
    Phase 1: Updated compaction.ts
- findCutPoint now returns CutPointResult with isSplitTurn and turnStartIndex
- Can cut at user, assistant, or bashExecution messages (never tool results)
- Added turnPrefixSummary support for split turns (parallel summarization)
- estimateTokens helper for context size estimation

Phase 2: Updated session-manager.ts
- CompactionEntry now has optional turnPrefixSummary field
- loadSessionFromEntries injects both summaries when turn was split

Phase 3: Updated agent-session.ts
- Overflow detection via isContextOverflow after agent_end
- Proactive compaction check on turn_end before next LLM call
- _abortingForCompaction flag to skip saving aborted messages
- Auto-retry after overflow recovery or proactive compaction
- New event fields: reason (overflow/threshold), willRetry

Phase 4: Updated interactive-mode.ts
- Shows reason in compaction status (Context overflow detected...)
- Shows retry status after compaction

Tests updated for new CutPointResult return type.

  • feat(coding-agent): maintain in-memory session entries for --no-session compaction support 
    SessionManager now tracks all entries in memory regardless of whether file
persistence is enabled. This allows compaction to work in --no-session mode
where no session file is created.

- Added inMemoryEntries array to store session entries
- All save methods now push to inMemoryEntries
- loadEntries() returns in-memory entries when file persistence is disabled
- File persistence only writes when enabled flag is true
- Session loading (constructor, setSessionFile) populates in-memory entries

- Rewrite tests to use RpcClient instead of raw process spawning
- All commands support optional correlation ID for request/response matching
