- Removed export leakage by demoting many helper and const symbols to module-local scope.
- Renamed underscore-prefixed internals and cache fields, then updated related references and `satisfies never` checks.
- Deleted obsolete logic branches and helpers, including harmony-stream interruption flow and unused benchmark runtime helpers.
- Updated Biome config and manifests by broadening lint coverage and removing an unused `@napi-rs/cli` dev dependency.
- Adjusted tests and utilities to use renamed test helpers and remove redundant private test-only helpers/locals.
- Restored formatDimensionNote bracket form '[Image: original WxH, displayed at WxH. Multiply coordinates by S to map to original image.]' that tests assert. The Bun 1.3.14 refactor regressed it to a less informative 'Image resized from …' line.
- Broadened bash-sixel-render multi-line styling assertion to accept both truecolor (38;2;) and 256-color (38;5;) SGR runs so CI runners with TERM=dumb don't fail. The contract being tested — every line carries its own SGR — is independent of color depth.
- Raised the Bun minimum version to >=1.3.14 across package metadata, install scripts, and changelog notes.
- Removed the Photon native image pipeline and added SIXEL-based `sixel` support in pi-natives.
- Migrated coding-agent image handling and resizing to `Bun.Image`, including updated tests and a JPEG quality bump to 80.

- Added untracked worktree baseline capture via `untrackedPatch` and synthetic tree diffing.
- Added fallback-aware backend ordering by collecting host candidates and retrying alternates on unavailable PAL.
- Hardened overlay mount lifecycle by removing stale overlays and deleting upper/work dirs after unmount.
- Refined ZFS clone deletion to validate ownership and remove dataset+origin only when checks pass.
- Updated ProjFS integration to use extended-info callbacks and symlink metadata reads.
- Updated rcopy path handling to absolutize paths, and added `writeTree` plus combined shell timeout checks.
- Extended file-display resolution to accept an immutable flag and suppress hashline anchors when immutable sources are requested.
- Plumbed immutable propagation through ReadTool and SearchTool so internal URL reads and searches pass that context.
- Added a regression test confirming artifact:// search output no longer includes hashline anchors.
- Added `./hashline` package exports and redirected callers to the new hashline entrypoint.
- Moved hashline logic out of `edit/` to `src/hashline` and removed `edit/modes/hashline`/`edit/line-hash` paths.
- Added hashline parsers, anchors, types, and diff helpers with stricter input and mismatch validation.
- Implemented preflight and cache-recovery execution flows to reapply edits and handle stale anchor mismatches.
- Documented the hashline API relocation as breaking changes in `CHANGELOG.md`.
Anthropic counts sessions by metadata.user_id. Without this fix, OMP
generated fresh random entropy on every API request, inflating the
session count and preventing backend attribution to the authenticated
account.
Changes:
packages/ai:
- resolveAnthropicMetadataUserId() now accepts JSON-format user_id
matching real Claude Code's getAPIMetadata shape
({ session_id, account_uuid, ... }). Previously only the legacy
cloaking format was accepted on OAuth, causing stable caller-supplied
values to be silently discarded.
- AnthropicOAuthFlow.exchangeToken() and refreshAnthropicToken() now
populate OAuthCredentials.{accountId, email} from the token response
account block, removing the need for a separate /api/oauth/profile
round-trip.
- AuthStorage.getOAuthAccountId(provider, sessionId) returns the OAuth
accountId for the session-sticky credential, used to build
account_uuid in metadata.user_id. Guards against misattribution for
API-key, runtime-override, env-key, and fallback-resolver paths that
do not record a session credential.
packages/agent:
- Agent.metadataForProvider(provider) resolves request metadata for
the given provider via the installed resolver, or returns the static
metadata value. The plain metadata getter now returns only the static
value; provider-aware resolution is explicit.
- Agent.setMetadataResolver(fn) installs a (provider: string) resolver
evaluated per LLM request in agent-loop, after getApiKey records the
session-sticky credential, so account_uuid reflects the credential
actually used.
- AgentLoopConfig.metadataResolver is called with config.model.provider
after getApiKey, overriding the static metadata field.
packages/coding-agent:
- AgentSession.#syncAgentSessionId installs a metadata resolver that
builds { user_id: JSON.stringify({ session_id, account_uuid? }) },
matching the Anthropic session attribution format. account_uuid is
only included for provider="anthropic" to avoid leaking the OAuth
identity to third-party Anthropic-format-compatible providers.
- sessionId getter prefers providerSessionId when supplied via
AgentSessionConfig so all API paths (getApiKey, direct calls,
metadata resolver) share the same provider-facing session ID.
- prepareSimpleStreamOptions stamps session metadata on direct calls
(runEphemeralTurn, compaction, branch summary, title generation) so
they share the same session bucket as Agent.prompt requests.
- generateBranchSummary and generateSessionTitle accept a
(provider: string) metadata resolver evaluated after their own
getApiKey call for correct credential attribution.
runSplitCommit reset the index and then re-staged each split via
git.stage.hunks, but stage.hunks builds its file map from the current
diff. After the reset, newly created files were untracked again and
absent from that map, throwing "No diff found for <path>" mid-split.
Preserve the original staged diff so new files remain locatable
through every split iteration.
Fixes#966
- Converted systemPrompt APIs and state types to ordered `string[]` across agent, AI, and coding-agent surfaces.
- Added `normalizeSystemPrompts` and applied it to context normalization before building provider request payloads.
- Updated AI providers to emit separate normalized prompt blocks/messages instead of a single merged system prompt.
- Removed dedicated `projectPrompt` state and remapped that context into system-context buckets in session, dump, and token accounting.
- Aligned tests and changelogs to pass and assert `systemPrompt` as arrays with ordered prompt semantics.
POSIX permits short syscalls (incl. open/read/stat) to be interrupted
by a signal and surface as EINTR. Optional sync git metadata helpers
(used by the status line) propagated the raw error and crashed the
agent. Add a small bounded retry around the sync stat/read calls and
classify persistent EINTR as 'metadata unavailable' so optional reads
fall back to undefined instead of throwing.
Fixes#899
- Removed PI_STRICT_EDIT_MODE gating from edit-mode resolution so model fallbacks now always apply.
- Stopped injecting PI_STRICT_EDIT_MODE in edit-benchmark.py and rate-edit-tool.py execution environments.
- Removed PI_STRICT_EDIT_MODE from environment-variable documentation and strict-mode test coverage.
- Added `disableReasoning` to `SimpleStreamOptions` and OpenAI completions, sending `reasoning: { enabled: false }` for OpenRouter requests to prevent reasoning models from consuming the full output budget on small calls like title generation.
- Fixed `canAppend` to accept `response.completed` as a terminal event, restoring websocket append reuse after codex sessions end.
- Replaced async blob-decoding and `addEventListener` with synchronous `onmessage`/`onopen`/`onerror`/`onclose` handlers and `binaryType = "nodebuffer"` for simpler, reliable message decoding.
- Simplified title generator to discard per-role thinking level and always pass `disableReasoning: true`.
- Removed title-source aware branching from session terminal-title and accent helpers, and updated callers to use session name plus cwd only.
- Dropped UUID-based recent-session naming by preferring explicit header titles or first user prompts and generating an "Untitled · <time>" fallback.
- Adjusted welcome session-row rendering for width-aware name truncation and disabled reasoning in title generation requests to keep terminal titles concise.
- Added a `reset` helper in git utilities to execute `git reset` with optional flags.
- Added support for `hard`, `mixed`, and `soft` mode options, an optional target revision, and signal forwarding to `runEffect`.
- Replaced the eager `markit-ai` singleton import with a lazy async factory in `markit.ts`.
- Initialized and memoized a `Markit` instance on first use, with later calls reusing it.
- Updated conversion helpers to receive the initialized `Markit` instance and execute conversions through a shared runner.
- 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.
- Added support for batch PR operations by accepting `pr` as string or array and dropping `worktree` input.
- Updated `pr_view` and `pr_diff` to normalize PR IDs, process multiple PRs in parallel, and emit combined summaries.
- Refactored checkout into `checkoutPullRequest`, added repo-locking, fixed worktree paths, and summary metadata outputs.
- Updated `remote.add` handling with URL-aware idempotency and per-repo queueing for serialized git mutations.
- Added temp-home test scaffolding and expanded tests for batched PR flows and remote add conflict/no-op cases.
- Removed `pi-natives` chunk language classifier modules and all core chunk subsystems (kind, state, render, edit, resolve).
- Removed chunk-mode CLI/read/edit entrypoints, including `read` command and chunk mode registration/prompt tooling.
- Removed chunk selectors from `read` and `grep` tools, switching behavior to raw/L-range handling.
- Fixed poll wait parsing to keep defaulting to `30s` when the provided value is empty.
- Extended optional git metadata checks to treat ENFILE and EMFILE like missing paths.
- Updated sync and async helper functions to return null for those filesystem errors instead of throwing.
- Documented the status-line branch-rendering fallback for ENFILE/EMFILE failures in the changelog.
- Enabled Biome VCS settings and expanded fix scripts with new `fix:all` and `fix:tools:all` commands.
- Updated `fix:ts` and `fix:tools` to separate changed-only checks from full-run formatting and generation tasks.
- Simplified edit-benchmark variant parsing by removing hardcoded validation logic, and removed deprecated flags from `run-rs-task.ts`.
- Added raw read output propagation so read/archive commands bypass anchors, line numbers, and chunk formatting.
- Fixed atom/hashline editing by tightening hashline prefixes and applying grouped anchor edits in stable order.
- Hardened chunk parsing and path handling by using `bigram_end` checks and resolving edit paths via shared `args.path` fallback.
- Updated path-related behavior for chunk, replace, patch, and hashline previews to honor optional edit paths.
- Removed mode-level param validators and replaced them with runtime handling, then removed obsolete validation tests.
- Added `atom` edit mode to `EditTool` with single-point hashline-style dispatch and `executeAtomSingle`.
- Added `AtomToolEdit`/`AtomParams` schema and `atom` prompt docs to require one op per edit entry.
- Changed `EditTool` entry processing to inherit per-entry `path` from a top-level request `path` fallback.
- Added top-level `path` defaults to patch and replace schemas and now reject missing entry paths.
- Added an `atom` streaming strategy and registered it in `EDIT_MODE_STRATEGIES` for live mode support.
- Enabled hashline read anchors for `atom` mode via `file-display-mode.ts` path-display logic.
- Added `atom` unit tests covering schema checks, anchor conflicts, and hash mismatch diagnostics.
- Added built-in model entries for gpt-5.5 and gpt-image-2, including updated context windows, token limits, and pricing.
- Updated generated-model policy application to set or clear applyPatchToolType based on inferred GPT-5 freeform rules.
- Changed Spark edit-mode resolution to return apply_patch by default, honoring explicit replace and strict-mode overrides.
- Added tests for GPT-5 freeform policy inference and Spark edit-mode default, variant, and strict-mode behavior.
Slots a new "apply_patch" variant alongside the existing edit modes
(replace, patch, hashline, chunk, vim). The mode accepts a single input
string containing a Codex *** Begin Patch / *** End Patch envelope,
parses it with a new lenient parser (heredoc-tolerant), and fans each
file-op out to the existing executePatchSingle so LSP writethrough,
plan-mode guards, fs-cache invalidation and diagnostics are shared
with the patch mode.
Exposes both tool shapes from the spec: the JSON function-tool variant
(§1.2, {input: string}) and the OpenAI custom-tool / Lark-grammar
"freeform" variant (§1.1, raw patch string). The edit tool advertises
a Lark grammar via customFormat and a wire name via customWireName;
openai-responses emits it as a grammar-constrained custom tool when a
model opts in with applyPatchToolType: "freeform" in models.json.
custom_tool_call / custom_tool_call_output are plumbed end-to-end
through the shared responses code (emission, streaming, history
replay), and the agent-loop dispatcher matches tool calls by either
name or customWireName so returned calls route correctly.
Also threads preview/diff rendering for apply_patch through the TUI
(tool-execution + edit renderer) so streaming patches show per-file
diffs like the other edit modes.
Default edit mode is unchanged (hashline); opt in via edit.mode or
PI_EDIT_VARIANT=apply_patch.
- Updated todo start handling to set the requested task to in_progress while demoting all other in_progress tasks to pending.
- Added task note rendering in summary output by prefixing each note line with "Note:".
- Set GIT_OPTIONAL_LOCKS to 0 in git execution options and added tests for out-of-order start jumps and note summaries.
ollama-chat was missing from buildNamedToolChoice, causing forced tool
calls (e.g. eager todo enforcement, submit-result) to be skipped for
Ollama Cloud models. Ollama supports tool_choice: "required" but not
named function forcing, so it maps to "required" alongside the
Google APIs.
- Removed the standalone vim tool and normalized built-in/requested tooling to edit.
- Updated session and SDK tool activation to dedupe lowercase names and track edit state via the edit key.
- Added vim-mode argument detection and delegated edit rendering/execution into Vim handlers under edit.
- Updated Vim step handling to auto-reorder numeric-positioned commands, including cc/C/S/s/i/I/A cases.
- Renamed prompt/changelog text and test expectations to reflect edit-only tool naming and usage.
- Added `vim` as a supported edit mode and resolved mode-specific active tool names.
- Migrated chunk-edit requests from legacy `op`/`content` to `path` plus `write`, `replace`, and `insert`.
- Replaced chunk-edit internals with `put`/`replace`/`delete` operations and ID-based selection.
- Updated chunk prompts/output docs to document ID-based selectors and `write: null` deletions.
- Switched chunk and grep render output to `@`/dash-style anchors and updated file-count behavior for multi-file edits.
- Updated multi-file result rendering with distinct file counting and pending-file progress indicator.
- Refreshed chunk-mode and chunk-tree tests for the new contract and anchor style.
- 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.
- Added `/rename <title>` slash command to set explicit session names and update header/tab titles.
- Added `session_name` status segment with hash-derived accent color for session titles.
- Fixed shell execution failure sanitization to preserve all `execResult` fields after redacting stderr.
- Fixed tool execution completion output to pass original `toolResult` text instead of sanitized `content`.
- 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
