- Added a unified eval framework with parser grammar, backend interfaces, and JS/Python execution result types.
- Added eval tool docs and updated prompts for fenced cells, `eval.py`/`eval.js`, and fallback behavior.
- Replaced the built-in `python` tool with `eval` across registry, rendering, interactive modes, and tool settings.
- Migrated Python execution runtime from `src/ipy` to `src/eval/py`, renamed state fields, and removed legacy introspection.
- Refactored browser tooling from in-process VM helpers to worker-managed tab supervisors and protocol transport.
- Added eval parser fallback and JS tool-bridge tests, updated imports, and removed obsolete python-mode suites.
- Documented and removed `utils/oauth` from the `ai` package entrypoint, noting it as a breaking change.
- Refactored `cli`, `auth-storage`, and `utils/oauth` to load provider modules via scoped dynamic `import()` calls.
- Removed top-level provider imports and barrel exports from `utils/oauth/index.ts`, streamlining oauth module loading.
- Consolidated OAuth symbol, type, and provider imports in coding-agent and tests to `@oh-my-pi/pi-ai/utils/oauth` modules.
- Defined `DEFAULT_LOCAL_TOKEN` locally in model-registry and removed its cross-package OAuth import usage.
- Removed `id` fields from todo models/fixtures and switched session clones to content-based task identity.
- Replaced `/todo_write` `replace` with `init`, updated setup schemas to `list`/`phase`, and append content-only items.
- Updated `/todo` command flows to match phases and tasks by names/content (exact/prefix/substr, case-insensitive), with no ID targeting.
- Updated rendering/output labels to `# Todos`, `formatPhaseDisplayName`, and Roman-numeral phase headings across todo views.
- Aligned prompts, changelog, and todo tests/fixtures with the new init and content-based todo-write contract.
- Added a `/context` slash command flow from registry to interactive-mode command dispatch.
- Added `handleContextCommand()` to the mode context interface and command-controller wiring.
- Added context usage breakdown utilities, cell allocation, and 20x10 usage rendering for token categories.
- Reworked compaction token estimation to use tokenizer counts, role aggregation, image token estimates, and fallback handling.
- Exported `resolveThresholdTokens()` as a public compaction helper.
- Updated loop command handling to toggle `/loop` without a prompt argument and prompt for the next user input to start repeating.
- Stored each user-submitted prompt as the active loop prompt while loop mode is enabled so iterations auto-resubmit that input after each yield.
- Introduced `pauseLoop` behavior to clear the captured loop prompt and cancel pending auto-submit when Escape is pressed, while `handleLoopCommand` now no longer disables mode automatically with arguments.
- Tracked locally submitted user signatures for both optimistic and streamed-queue submissions in interactive-mode context state.
- Updated user message_start handling to avoid re-clearing the editor and re-adding chat for locally originated messages.
- Cleared consumed local signatures on queued-message restore and added tests for queued, external, and optimistic message_start editor behavior.
- Added loop-mode command handling in interactive mode, including enable/disable toggling, repeated auto-submission scheduling, and Escape-based cancellation.
- Propagated loop mode state to the status line via a renamed `mode` segment that now renders plan or loop status, and updated presets/theme assets for the new loop icon.
- Migrated persisted status-line segment usage from `plan_mode` to `mode` in configuration defaults and normalization so legacy settings continue to load.
Before this change, every navigateTree → renderInitialMessages call path
performed two independent O(N) session-tree walks:
1. agent-session.ts:6586 buildDisplaySessionContext() [inside navigateTree]
2. ui-helpers.ts:402 sessionManager.buildSessionContext() [inside renderInitialMessages]
Changes:
- agent-session.ts: navigateTree() now calls sessionManager.buildSessionContext()
once, derives the display (deobfuscated) context from the raw result, and
returns the raw SessionContext in the result object.
- ui-helpers.ts: renderInitialMessages() accepts an optional prebuiltContext
parameter; reuses it when provided, falls back to buildSessionContext() otherwise.
- interactive-mode.ts: forwards prebuiltContext through the wrapper.
- modes/types.ts: updates InteractiveModeContext interface to match.
- selector-controller.ts: passes result.sessionContext from navigateTree into
renderInitialMessages(), closing the deduplication loop.
Bench (100-msg session, 200 iterations):
two walks [BEFORE]: 0.0702ms/op
one walk [AFTER]: 0.0298ms/op
Saved: 0.0404ms/navigation (57.5% reduction per navigate)
Tests: render-initial-messages-dedupe.test.ts asserts buildSessionContext is
called 0 times when a prebuilt context is passed, 1 time as fallback.
- Added an `irc_message` session event carrying custom IRC messages and emitted it when IRC records are created.
- Registered an IRC message handler in EventController that skips duplicate messages by role, custom type, and timestamp.
- The handler now appends IRC messages to chat, resets read grouping, and triggers a UI render.
- Replaced `AgentTool` `nointent` and `deriveIntent` with a unified `intent` option that supports `omit`, `optional`, `require`, or a callback function.
- Updated agent tool schema injection and execution paths to inject `_i` as required/optional/omitted and to derive intent through the new `intent` callback.
- Aligned atom-edit tests with the updated default sed behavior (`g` now off by default and explicit `g: true` for global replacement).
- Added `nointent` and `deriveIntent` to `AgentTool`, and made intent-schema injection honor `PI_NO_INTENT` plus per-tool opt-outs.
- Updated tool execution and streaming UI handling to derive a fallback intent when `_i` is absent, without aborting on derivation failures.
- Marked several coding tools as `nointent` and added `deriveIntent` callbacks where needed, then relaxed prompt language to indicate intent is present on most tools.
- dropSession: close persist writer before deletion to prevent EPERM
on Windows where an open file handle blocks unlink
- #runNewSessionFlow: guard UI reset on newSession return value;
session_before_switch hook cancellation now prevents chat state
being cleared and success banner being shown
- Added `AgentRegistry` singleton with session registration/unregistration and IRC routing metadata for peer lookups.
- Added IRC messaging prompts and tooling with `irc.enabled` setting, `list/send` tool paths, and peer roster rendering.
- Changed `/btw` to session-side `runEphemeralTurn`, added background IRC exchange flushing, and fixed empty-input checks.
- Added unit tests for IRC tool and BtwController ephemeral behavior, including disabled, busy, not-found, and abort cases.
/drop works like /new but permanently deletes the current session file
and artifacts instead of flushing (saving) it. Useful when the session
should not be kept.
- add drop?: boolean to NewSessionOptions
- branch in AgentSession.newSession(): skip flush, delete via
FileSessionStorage.deleteSessionWithArtifacts when drop=true;
deletion failure is non-fatal (logged, new session still starts)
- wire handleDropCommand() through InteractiveModeContext interface,
InteractiveMode delegation, and CommandController implementation
- guard: shows error if session has not been saved yet (no file to drop)
- register /drop in builtin-registry adjacent to /new
- Added `note` support to todo-write with `op: "note"` and required `text` input.
- Added optional `notes: string[]` to todo models and preserved notes in cloning and session task mapping.
- Implemented `op: "note"` append flow and markdown `>` block serialization/parsing for todo import/export.
- Updated HUD todo rendering to append superscript `+N` note markers and show in-progress note bodies.
- Documented note operation, required text field, and note rendering rules in todo-write docs and changelog.
- Added /todo export and /todo import commands to write/read markdown todos, defaulting to TODO.md.
- Changed /todo append from JSON payloads to tokenized [<phase>] <task...> input with quoted tokens.
- Changed /todo start/done/drop/rm matching to fuzzy-resolve task or phase names in TodoCommandController.
- Removed /todo replace from todo-command builtins in CHANGELOG and command registry.
- Added a private #currentPhases helper that reads todo phases from the latest session entries.
- Updated /todo handlers to use #currentPhases so existing todo states are loaded from entries when available.
- Added a fallback to session.getTodoPhases when no entry-derived phases exist.
- Added `openai` and `openai-codex` as image providers and let `providers.image=auto` prefer GPT images.
- Updated settings, selector, and SDK wiring so OpenAI image providers pass through `setPreferredImageProvider`.
- Replaced Gemini-only image tooling with `image-gen` and added OpenAI/Codex hosted-image execution with SSE parsing.
- Added image-gen and handoff tests, including final-yield no-compaction regression and OpenAI payload/header assertions.
Two regressions from 33dfce738:
1. selector-controller.ts imported nonexistent clearPluginRootsAndCaches
(was clearClaudePluginRootsCache). The previous commit collapsed the
inline closure that invalidated fs caches for plugin JSON files into
a direct function reference that doesn't exist. Restored the original
closure with its fs cache invalidation logic.
2. scrollToSelectedEntry() snapped oversized entries back to their top
on every PgDn/PgUp, defeating the line-scroll fallback. The condition
'entryTop < scrollOffset' fires whenever the user pages down within
a tall entry. Fixed: only snap when the viewport has no overlap with
the entry (completely above or completely below it).
- Replace `ReturnType<typeof this.ctx.ui.showOverlay>` with concrete
`OverlayHandle` type from @oh-my-pi/pi-tui
- Remove `as any` casts and redundant `as SessionMessageEntry` in
#loadTranscript; discriminated union narrowing on `entry.type` and
`msg.role` is sufficient
- Add missing `replaceTabs()` on collapsed user/developer preview text,
matching every other collapsed render path
- Canonicalized file and CLI defaults from `read` to `open` across tool registration and prompts.
- Added `resolveToolAlias()` and applied alias-normalized tool selection so legacy `read` maps to `open`.
- Updated runtime, UI, and export layers to treat `open` as first-class while preserving `read` compatibility.
- Renamed read prompt docs to `open.md`/`open-chunk.md` and refreshed system guidance to recommend `open`.
- Updated tool-related tests and expectations from `read` to `open` (including test fixtures and aliases).
- Standardized missing-file read errors and now return `File not found: <path>` for absent edit targets.
- Centralized AI provider, usage, and OAuth helpers into shared modules to remove duplicated logic.
- Migrated OAuth/API-key login flows to shared factory helpers and removed inline prompt/token-exchange code.
- Reused shared tools and formatter utilities for discovery, stream tails, LSP batching, and source formatting.
- Consolidated repeated test helpers and fixtures into shared modules, replacing inline helper duplicates.
- Added a new read.toolResultPreview boolean setting defaulting to false to control inline read result rendering.
- Updated read tool group rendering to show inline previews only when enabled and to hide duplicate summary rows for previewed entries.
- Passed the setting through event and UI helper constructors and added tests for default-off behavior and the duplicate-preview summary case.
Three issues from first test:
1. Viewer was cramped at bottom of screen because it replaced the
editor container inline. Now uses TUI's showOverlay system with
anchor=bottom-center, width=100%, maxHeight=100% for full terminal.
2. Text was truncated at hardcoded 90 chars. Removed MAX_TOOL_RESULT_LINE_WIDTH
— let the TUI framework handle wrapping at actual terminal width.
3. Enter key didn't trigger expand/collapse. Added matchesKey(keyData, 'enter')
alongside raw '\r'/'\n' checks.
Also: overrides Container.render() in viewer mode to produce viewport-
sliced output directly, with proper height computation from terminal rows.
- Added vim tool-call IDs across EventController, UiHelpers, and ToolExecution for per-call preview mapping.
- Extended Vim type and command parsing with update/write, edit, global, yank, and put handling.
- Added Vim engine support for new commands and motions, including gJ, g*, g#, g_, |, and gu/gU/g~.
- Reworked Vim tool flow to cache per-file engine clones, reuse tool details, and stream inserts in chunks.
- Updated vim.md and changelog to document new vim keys, ex aliases, and fixed :global preview behavior.
- Added parser and renderer tests plus a tmp/vim_test.txt fixture for chunked, cursor, and partial-insert cases.
- Removed `SearchDb` APIs and `searchDb` fields, dropping db-backed state from native and agent sessions.
- Replaced crate export `fff` with `fd`, moving fuzzy-find bindings into `fd.rs`.
- Removed `SearchDb`/picker fast-path logic from `glob` and `grep`, simplifying scan flow and dropping db args.
- Removed `SearchDb`/`getSearchDb` wiring from extension, tool, and task context constructors across coding-agent.
- Added over-indentation validation warnings in chunk-edit normalization for suspicious `~` body line formatting.
- Removed `bytes`, `fff-grep`, `fff-search`, and `blake3` deps, adding `grep-searcher = "0.1"`.
- Added multi-file edit payload support by requiring per-entry `edits` arrays across patch, hashline, replace, and chunk modes.
- Changed edit schemas and validators to move `path` (and `sel`->`path`) and op data into each edit entry.
- Changed edit execution flow to parse `file:selector` paths, run single-entry executors per file, and return grouped per-file results.
- Updated chunk diff rendering and test expectations to emit consistent anchor gutters with spaced pipes and `^` head-line markers.
- Propagated session title source through terminal-title update calls so auto and user names are handled consistently across controllers.
- Suppressed auto-generated names in status-line segments and completion messages by falling back to cwd-based titles.
- Updated title formatter tests to verify auto-generated and user-specified session titles produce different terminal labels.
- Add /rename <title> slash command to set an explicit session name,
updating the session header, terminal tab title, and status line
- Add session_name status segment: displays the session name on the
right side of the status bar with a stable djb2-hash-derived accent
color unique to each name; shown in all presets when a name is set
- Add setSessionName source tracking ('user' vs 'auto'): auto-generated
titles are silently ignored once the user has explicitly set a name,
preventing the async title generation from overwriting a /rename
- Sanitize session names at storage time: strip C0/C1 control characters
(including ANSI ESC) via static #sanitizeName before storing, blocking
escape sequence injection into the TUI, terminal title, and session file
- Extend sanitizeStatusText to cover the full C0/C1 range as
defense-in-depth (superset of the previous \r\n\t-only strip)
- Use stored (sanitized) name for showStatus message and terminal title
in handleRenameCommand, not the raw user input
- Guard terminal title update in auto-title path via titleSource === 'auto'
so a user rename is never overwritten by a late-resolving LLM call
- Reset #titleSource in #newSessionSync so each new session starts fresh
- Thread source parameter through AgentSession.setSessionName wrapper;
extension API and RPC set_session_name treated as 'user' intent

- Updated input controller to handle remaining text from slash commands and use it as prompt input.
- Extracted image metadata detection and MIME type utilities to @oh-my-pi/pi-utils package for shared use across projects.
- Consolidated image-input.ts and mime.ts modules into image-loading.ts with simplified API removing redundant metadata parameters.
- Updated all import paths across coding-agent to use readImageMetadata from @oh-my-pi/pi-utils instead of local utilities.
- Added peek-file utility module to @oh-my-pi/pi-utils with buffer pooling for efficient file header reading.
- Added asynchronous LSP server discovery and warmup at startup via `discoverStartupLspServers()` function.

- Added `LspStartupServerInfo` type to track LSP server status (connecting, ready, error) throughout lifecycle.
- Changed LSP server warmup from blocking synchronous operation to non-blocking background task.
- Refactored interactive mode to subscribe to LSP startup events and display real-time server status updates.
- Extracted prompt rendering and formatting utilities from coding-agent to centralized pi-utils package with new API surface (prompt.render, prompt.format, prompt.registerHelper).
