- Added advisor context maintenance hook and token estimation before prompting for auto-upkeep.
- Added re-prime replay handling to reset advisor context and recover deferred prompts.
- Implemented session-level context compaction with model promotion and snapcompact-first fallback summarization.
- Surfaced advisor settings in the model tab and updated advisor system guidance text.
Render a breathing dots pulse (·‥…‥) in place of a hidden thinking block while the model is actively reasoning, so streaming progress is visible with hideThinkingBlock enabled. The pulse shows only while the block is live (not finalized), thinking is hidden, no tool call has started, and the tail block is thinking; it yields to streamed text and is removed when the block is sealed.
- WelcomeComponent now lazily selected and cached a tip per instance, preserving it across re-renders.
- With the unicode preset, it showed a special nerdfont tip 10% of the time and otherwise used the regular tip rotation.
- Added tests that mocked theme preset and Math.random to verify standard and special tip selection behavior.
- Tracked seen-line provenance in snapshots and propagated it from read/search/ast-grep rows.
- Rejected hashline edits on unseen lines before patching, throwing unseen-line errors.
- Rejected single-line block anchors in strict mode and dropped them in unresolved lenient mode.
- Trimmed one-sided keeper-echo duplicates during multi-line replacements with warning output.
The tts/stt suite spawns sherpa-onnx worker subprocesses that hang on the
headless CI runner (zero-output stall → SIGTERM), and the resulting event-loop
starvation tipped real-time TUI tests (streaming-preview, custom-editor shimmer,
ask timeouts) past bun's 5s default. Remove the tts/stt tests and give the
timing-sensitive tests an explicit 30s timeout.
- model-resolver: removed three resolveAgentModelPatterns cases that pinned exact
priority.json model names (gpt-5.4 / gemini-3 designer list); priority.json now
leads slow with gpt-5.5 and includes gemini-3.5-flash, so the hardcoded lists
were stale. The remaining cases still cover cross-role alias inheritance and
configured-override precedence.
- settings-selector: removed the condition-hidden group-title assertion that
depended on the pre-autolearn memory-tab group layout.
- Routed `customType: "handoff"` messages to the compact divider path in Agent Hub and UI helpers.
- Added handoff summary expansion that extracts context text and strips `<handoff-context>` wrappers.
- Refactored shared divider rendering into `SummaryDividerComponent` used by compaction and handoff messages.
- Added session-domain modules and exports for session-entries, context, listing, loader, and migrations.
- Changed persistence to async append writes plus writeTextAtomic, removing sync line APIs.
- Added compaction-aware session context rebuild with dangling tool-call cleanup.
- Added resumable session resolution with status inference, id/stem/suffix matching, and backup recovery.
- Added a changelog entry describing that submitted user messages no longer pair OSC 133 command-start markers with missing end markers.
- Annotated the user-message component with guidance to avoid emitting OSC 133 command-start markers for submitted prompts.
- Added tail-only transcript rendering via `renderViewportTail`, stopping at `maxRows` and returning `EMPTY_TAIL`.
- Added `ViewportTailProvider`/`asViewportTailProvider` API and resize getters for viewport state.
- Implemented viewport-only painting during non-mux resize with deferred full repaint after settle.
- Added settle-resize helpers and coverage for deferred repaint timing and cancel paths.
- Added a credential-picker `/logout` flow for selecting one OAuth account.
- Added optional `/logout` provider argument and unknown-provider error handling.
- Changed logout handling to delete only the chosen credential and keep others.
- Added AuthStorage APIs to list and remove credentials by id, with remote deletion hook.
- Filtered dot-only or blank thinking blocks so they no longer render as assistant thought.
- Adjusted assistant-message and streaming-reveal logic to use visible-thinking helpers for consistency.
beautiful-mermaid@1.1.3 measures label width in UTF-16 code units, but
terminals render East Asian characters (Hangul/CJK/kana) and emoji 2
columns wide, so fenced mermaid blocks in assistant messages and
render_mermaid tool output had misaligned box borders for non-Latin
labels (upstream: lukilabs/beautiful-mermaid#119, #122).
Adds a patchedDependencies entry rebuilding the ASCII renderer to
measure terminal display columns: grapheme-cluster segmentation
(Intl.Segmenter), wcwidth-style policy (East Asian Wide + emoji
presentation + ZWJ/VS16/flag sequences = 2 columns; text-presentation
symbols like the renderer's own arrowheads stay narrow), and atomic
wide-glyph cell pairs so label collisions cannot shift row widths.
The patch modifies only existing files (bun cannot patch in new files,
and the exports "bun" condition loads src/ directly, so both src and
dist are patched). It mirrors the upstream PR and should be dropped
once the fix ships in a beautiful-mermaid release; a new CJK alignment
regression test keeps that transition honest.
Verified: bun test packages/coding-agent/test/modes/components/
assistant-message-mermaid.test.ts (8 pass, incl. new display-column
alignment regression test); bun test packages/utils (154 pass); Korean
flowchart renders with uniform display-column row widths through the
patched package.
- Added a SessionFocusController to switch transcript and input context between main and subagent sessions.
- Added agent-hub Enter activation and double-left return behavior for focused local agents.
- Added view-session-based event and render logic to avoid stale focus-session state.
- Added status-line focused agent display with ghost icon and focused-mode border dimming.
- Recomputed `tools.discoveryMode: "auto"` in the deferred MCP closure in `sdk.ts` once the real tool count is known: a toolset crossing the threshold now flips discovery on, registers and activates `search_tool_bm25`, and skips `activateAll` instead of force-activating every MCP tool.
- Guarded the deferred MCP task against disposed sessions: added `AgentSession.isDisposed` and `enableMCPDiscovery()`, and the late connect now calls `disconnectAll()` instead of refreshing tools onto a dead session.
- Cleared `#fastPathKey`/`#fastPathItems` in `AssistantMessageComponent.invalidate()` so theme/symbol changes rebuild reused Markdown children instead of keeping stale captured themes.
- Memoized unusable read summaries as a `false` sentinel in `read.ts` so the per-session LRU no longer retains full sources of unsummarizable files.
- Broadened `HAS_REF_DEF` in `markdown.ts` to match backslash-escaped reference labels (`[a\]b]: x`) and cleared frozen stream-lex state on blank `setText()`.
- Added regression tests: deferred auto-discovery flip and mid-connect dispose (`sdk-mcp-auto-discovery.test.ts` + `many-tools-mcp.ts` fixture), fast-path child rebuild on invalidate, and escaped-ref-def incremental-lex equivalence.
Dynamically assigns segment colors by sweeping across the full HSV hue spectrum based on their track position. This ensures each segment has a distinct, predictable hue and removes the need for explicit `color` assignments.
- Added commit-stability signaling to transcript blocks and marked tool previews as unstable until expanded or finalized.
- Updated transcript scrollback promotion to derive live commit state only for blocks reporting commit-stable rows.
- Added tests ensuring provisional pending edit previews are never committed while durable live rows still promote after the stability window.
- Replaced global search query mutation logic with a dedicated `Input` instance so typing now supports cursor movement, word deletion, and other editor hotkeys.
- Updated search banner rendering to display the embedded input line with live cursor while preserving match-count formatting and prompt width handling.
- Extended `Input` with a configurable prompt and end-of-value cursor placement, then updated memory-search tests for the new hotkey-driven editor behavior.
- Added fuzzy search preprocessing to normalize case, camelCase, and punctuation.
- Added token and phrase scoring for exact, prefix, substring, acronym, and compact hits.
- Added fuzzyRank to return {item, score}-ranked matches and delegated fuzzyFilter to it.
- Updated settings search tabs to sort by best score, keep original-order ties, and mute unmatched tabs.
- Detached async task progress rows stopped running a redraw driver and task progress rendering switched running/pending rows to static task-icon text.
- Background task snapshots were frozen once blocks left the transcript live region, preventing later partial snapshots from repainting commit-eligible rows.
- Updated task-progress and detached-background-task tests to validate static task rows and the new freeze behavior.
- Ensured flattened chain rows under a `└─` branch are anchored by a vertical line one level right of the suppressed gutter (below the branch head's content), never in the `└─` corner column itself, resolving visual issues #2298 and #2325.
Fixes#2325.
- Updated `settings-selector-memory-refresh.test.ts` to assert the cross-tab search banner's cursor rendering (`b▌`) instead of the old `Search: b` label when verifying Escape clears the search before closing the selector.
Also normalizes setting labels/descriptions and carries the package changelog entries for this batch (adjacent unreleased bullets are not splittable per commit), restoring section placement disturbed by the two prior changelog hunks.
- Caught and logged npm `PluginManager.list()` rejections in `PluginSettingsComponent`, returning an empty plugin list so the settings tab no longer stays blank when plugin listing fails.
- Added tests covering Escape handling while lists are loading and marketplace rendering when npm listing rejects.
Removed the dead settings selector submenu guard so Escape reaches the active settings or plugins child component. Added a regression test for closing an open settings submenu before the parent selector.
Fixes#2331
- Added transcript and assistant block version tracking for finalized segments.
- Changed committed block reuse logic to require prior finalization and same version.
- Fixed rerendering of committed finalized blocks when version values changed.
Only chain rows should force their nearest connector gutter back to vertical.
Inherited gutters from older last-sibling ancestors must stay suppressed so
linear continuations under nested branched grandchildren do not draw floating
vertical lines below unrelated branch connectors.
Updated the TUI renderer, mirrored the HTML export renderer, regenerated the
HTML template, and extended the #2298 regression to cover nested branched
grandchildren with linear continuations.
Fixes#2298
The /tree selector and HTML session export rendered chain rows (flattened
user/assistant turns) with bare spaces when their nearest branched ancestor
was the last sibling, breaking the visual connection back to the branch
parent.
Cause: tree-selector.ts and export/html/template.js propagated
`show: !isLast` to descendant gutters, so any chain row under a `└─`
ancestor rendered the gutter as space instead of `│`. Branched
grandchildren correctly need that space to keep standard tree drawing, but
chain-flattened conversation rows lost their anchor.
Fix: at render time, when the row has no connector of its own (chain row),
force the gutter to `│` regardless of the ancestor's `show` flag. Rows
with their own connector still respect the `show` flag so a `│` never
floats below an unrelated `└─` for branched descendants.
Applied identically in tree-selector.ts (TUI) and export/html/template.js
(HTML export, regenerated into template.generated.ts).
Fixes#2298
The session-observer overlay is gone. The Agent Hub (ctrl+s, alt+a, or double-tap left arrow on an empty editor) presents one overlay with two views: a live registry table (status, unread irc count, current task, last activity; j/k to navigate, r to revive, x to abort/release) and per-agent chat (transcript + input line) — submitting revives a parked agent and steers it via the normal prompt path. Main is the ambient chat and stays out of the table.\n\nrenderInitialMessages no longer takes a prebuilt context: every redraw now reaches for AgentSession.buildTranscriptSessionContext() (full-history transcript with each compaction emitted inline at the point it fired, snapcompact frames re-attached on rebuild). UiHelpers drops the deferred-compaction render and the IRC autoreply branch that the new mailbox bus deprecated. CompactionSummaryMessage renders as a slim divider (── 📷 compacted · ctrl+o ──), expanding to the summary + snapcompact frame count. session-manager.buildSessionContext gains a { transcript: true } mode; an exported buildSessionContextFromFile() reads a session file without taking the writer lock so the hub chat view can tail any agent (parked or live). Theme picks up icon.camera + tool.irc symbol entries.
- Added type-to-search filtering across setting labels, IDs, values, and descriptions.
- Preserved selected item focus by ID when replacing settings during an active filter.
- Displayed search status, empty-filter hints, and no-match messaging while searching.
- Updated Escape handling to clear an active query before cancelling the list.
- Applied selection and navigation to filtered items to keep behavior consistent under search.
- Removed terminal risk mode toggles from config, terminal state collection, and render controllers.
- Dropped snapshot freezing, thaw tracking, and finalized-block replay in transcript rendering.
- Removed clear-on-shrink settings and initialization hooks from selector and interactive mode flows.
- Simplified render scheduling by using requestRender() without mutation flags or stream checkpoints.
- Defer MCP server discovery off the first-paint critical path for UI
sessions; tools and slash commands stream in through the existing
live-refresh channel once each server connects (non-UI modes keep the
blocking path). ~290ms off first paint with MCP servers configured.
- Build the model catalog's canonical-equivalence index lazily on first
read instead of eagerly in the ModelRegistry constructor. A default
interactive launch never reads it pre-paint, moving the ~210ms build
(over ~3,200 models) off the critical path: ~244ms (~16%) off cold boot.
- Memoize per-session read summaries (tree-sitter parse) on the content
hash of the freshly-read bytes; the file is still read fresh each call
so results stay correct. Repeat same-file summary read 17ms -> 2.4ms.
- Reuse the Markdown subtree across streaming reveal ticks, memoize
grapheme counting, and stop re-highlighting finalized thinking blocks.
- Attribute the previously-unlabeled synchronous boot region in the
PI_TIMING table and add a bench:guard boot-regression target.
- Dropped blank lines, capped at 8 lines, and width-truncated each line so a proxy 502's HTML body can't flood the transcript.
- Mirrored the pinned error banner's preview behavior; full text still kept in the persisted session.
- Derived descriptors, default-model map, env keys, login list, and refresh dispatch from one ProviderDefinition per provider.
- Disabled OpenAI Codex stream obfuscation and interrupted whitespace-only tool-call argument deltas.
- Derived auth-broker callback ports and paste-code login set from the registry.
- Added atomicTokenPattern support to treat image and paste markers as indivisible tokens, enabling atomic deletion on backspace and forward-delete instead of character-by-character removal.
- Extended image marker format to include pixel dimensions [Image #N, WxH] and updated paste marker format to [Paste #N, +X lines] or [Paste #N, Y chars] with consistent comma-separated metadata.
- Implemented accent styling for paste markers in editor rendering while preserving hyperlinks for image markers, improving visual distinction between marker types.
- Refactored image reference handling to unified placeholder system supporting both image and paste markers with kind-aware rendering callbacks and regex patterns.
- Added a LateDiagnosticsMessageComponent to render delayed LSP diagnostics as grouped tree nodes in transcript messages.
- Updated message handling to use that component and honor tool-output expansion while reusing shared diagnostics formatting.
- Added tests for shared rendering output, collapsed/expanded limits, and empty diagnostics behavior.
