- Removed todo spinner interval state and rendering hooks from InteractiveMode, and in-progress or active-matched todos now use the static running glyph.
- Removed spinner-driven matcher caching and render updates from todo list generation so running state is based on direct content matching.
- Added build-session context tests that remove dangling assistant `toolCall` entries and drop trailing assistant turns that contain only tool calls.
- Enhanced markdown rendering to insert a painted theme swatch before matching inline hex colors in prose and code spans.
- Skipped short numeric-only 3- and 4-digit values in plain text so issue-like references do not get swatches.
- Added `colorSwatch` to symbol themes and added tests for swatch rendering and surrounding-style preservation.
- Used cacheRead + cacheWrite + input as the denominator for an accurate hit rate.
- Previous logic excluded uncached input tokens, overstating the hit rate for providers that report all three fields.
- DeepSeek (cacheWrite=0) still yields correct hit/(hit+miss) with the new formula.
- Removed Ghostty-specific hardware-cursor forcing from TUI preference resolution and dropped the redundant terminal-cursor marker flag.
- Updated interactive mode editors to use `ui.getShowHardwareCursor()` so cursor mode now follows actual hardware-cursor visibility.
- Reworked terminal regressions tests to assert Ghostty respects the requested cursor preference and only emits cursor-show output when enabled.
- Rendered the plan review "keep context" selector label with the session context usage percentage when available.
- Kept the fallback label unchanged when context usage data was unavailable.
- Added coverage asserting both the percentage label and fallback label in plan review tests.
Fixes#1458
- Added prompt_cache_hit_tokens / prompt_cache_miss_tokens parsing in
parseChunkUsage for DeepSeek's prompt cache format where
prompt_tokens = hit_tokens + miss_tokens.
- DeepSeek formula: input = prompt_tokens - hit_tokens (= miss, billed input),
total = input + output + hit_tokens (avoid double-counting miss in cacheWrite).
- Added cache_hit status line segment showing cache hit rate:
rate = cacheRead / (cacheRead + cacheWrite) x 100%.
- Added cache_hit to all status line presets.
Ghostty/cmux continued to show trails after hiding the hardware cursor because OMP switched to a blinking software cursor glyph. Keep editor cursor markers enabled when hardware cursor display is requested, but hide the actual hardware cursor on Ghostty; this gives the TUI a cursor position without emitting any cursor glyph. Also preserve the history-anchor cursor exit before public insertText, as flagged in PR review.
Constraint: Ghostty leaves visible trails for both hardware bar cursors and blinking software cursor cells during rapid input-row repaints.
Rejected: Only removing SGR blink | PTY writes still emitted the cursor glyph, so glyph afterimages could still accumulate.
Rejected: Ignoring the PR comment | public insertText callers bypass typed-character history-exit behavior.
Confidence: high
Scope-risk: moderate
Directive: Keep cursor-marker mode separate from actual hardware cursor visibility; callers that decide editor rendering must not use getShowHardwareCursor as a proxy.
Tested: bun test packages/tui/test/editor.test.ts packages/tui/test/render-regressions.test.ts; bun test packages/tui/test/*.test.ts; bun run check; Ghostty-env PTY capture of installed omp while typing abcdef emitted zero cursor-show writes, zero blink SGR, and zero input cursor glyph bytes before shell restore.
Four refinements to the sticky Todos panel on top of the live SessionObserverRegistry linkage:
- Cube animates whenever any visible open todo is "live" (in_progress, or a still-pending todo with a matching in-flight subagent). The previous subagent-only gate left lone in_progress rows on the static '⟳' fallback; ticking on an orphan in_progress row is the correct "still open" signal.
- 'normalizeForTodoMatch' now collapses any non-alphanumeric run to one space, so subagent descriptions with '#', '.', ':' etc. match todo content that omits the punctuation. Fixes the case where 3 subagents were spawned but only 2 of 3 matching todos lit up because the matcher's normalizer collapsed whitespace but left '#' intact.
- New '#reconcileTodosWithSubagents' runs on every observer-registry change and auto-checkmarks any pending/in_progress todo whose content matches a 'status === "completed"' subagent description. Failed/aborted subagents intentionally don't auto-flip - those stay open for the user (or next agent turn) to decide.
- All-done close animation: when every visible task is closed, fold the panel away over ~1.4s. A 900ms celebratory frame holds the bright bold "Todos ✓" header so the user can read the final checkmarks, then a fade through 'muted' / 'dim' with rows progressively dropped from the bottom. '#todoClosingState' state machine plays the animation exactly once per open->all-closed transition and aborts cleanly if a new open task arrives mid-animation.
Verification:
bun test test/tools/todo-write.test.ts → 24 pass / 0 fail (one new case for # punctuation tolerance)
bun run check → biome + tsgo clean
The always-on Todos panel above the editor pinned to the first 5 tasks of the active phase, so each todo_write flip mutated at most one row (color + strikethrough) and the +N more hint only shrank at end-of-phase. Marking task 1 done left tasks 6,7,... invisible until tasks 1-5 were all closed.
Introduce selectStickyTodoWindow(tasks, maxVisible=5) — returns up to 5 open (pending / in_progress) tasks in original phase order plus the count of remaining open tasks for +N more. When every task is closed, falls back to the trailing window (with +N more suppressed) so the panel keeps useful context until getActivePhase walks to the next phase. The collapsed branch of #renderTodoList now uses it; the expanded branch is untouched.
- Added a new ultrathink mode module with standalone, case-insensitive detection, rainbow editor highlighting, and a hidden notice payload.
- Updated `CustomEditor` and the shared TUI `Editor` to support optional zero-width text decoration and apply the `ultrathink` styling during input rendering.
- Extended `AgentSession` prompt handling to append the hidden ultrathink notice after user turns in both streaming and non-streaming message flows, excluding synthetic messages.
- Handled "incomplete" stop reasons in session recovery and auto-compaction workflows.
- Dropped the prior assistant turn before attempting recovery on incomplete-length stops.
- Expanded auto-compaction reason types and triggers to include "incomplete".
- Updated internal URLs parsing internals, export order, tests, and Obsidian URI prompt docs.
- Replaced the `keepaliveWhile` Promise wrapper with a new `EventLoopKeepalive` class that registers and disposes an interval timer through `Symbol.dispose`.
- Updated `Agent` to instantiate `EventLoopKeepalive` via `using` during prompt execution instead of manually managing an interval.
- Wrapped interactive mode's await path with the new helper and removed redundant `keepaliveWhile` usage from the CLI entrypoint.
- Redesigned hashline patch syntax from anchor-based (`A-B:`) to hunk-header format (`@@ A..B @@`) with unified-diff compatibility.
- Removed `autoDropPureInsertDuplicates` option and simplified apply behavior to preserve duplicated boundary and context lines.
- Changed repeat operator from `^A-B` to `&A..B` and range separator from `-` to `..` for consistency with hunk-header syntax.
- Added image resizing and dimension notes to eval tool output; improved write tool hashline header sanitation for legacy formats.
- Removed 521 lines of boundary-duplicate absorption code and simplified parser to auto-convert bare body rows and unified-diff contamination.
- Replaced 4-hex content-derived file hashes with 3-hex opaque tags minted by InMemorySnapshotStore, making tags session-bound pointers rather than content fingerprints.
- Removed lru-cache dependency; replaced LRU-bounded per-path rings with a flat 4096-slot global ring using a scrambled permutation to prevent LLM tag extrapolation.
- Made SnapshotStore required in Patcher (was optional); tag resolution now drives stale-anchor detection instead of recomputing hashes at apply time.
- Changed literal payload sigil from `|` to `+` and accepted `^A` shorthand for `^A-A`; added lenient recovery for bare bodies, lone `-` rows, and overlapping bare/concrete block pairs.

Avoid rendering the pre-reset transcript during /new and force the final new-session frame through the clear-scrollback path so the cursor and prompt land with the replacement transcript.
Fixes#1295
Add an explicit clear-scrollback render option for intentional transcript replacement and use it when switching, branching, reloading, or creating sessions. Regular active redraws continue to preserve terminal scrollback.
Fixes#1295
- Added Symbol-keyed sidecar on each AgentMessage to memoize estimateTokens, with a cheap content fingerprint to detect in-place mutations.
- Fixed stale cache on same-length replaceMessages, post-hoc error attachment, and branch rebuild edge cases.
- Fixed usage fetch error backoff: stamped fetchedAt on failure so the 5-min TTL also gates retries during outages.
- Extracted computeNonMessageBreakdown as shared helper to prevent drift between status-line and context panel token counts.
Separated model selector provider tab labels from provider ids so human-readable labels like Ollama Cloud refresh and filter the underlying ollama-cloud models.
Fixes#1153
- Removed the exported formatBashFixupNotice helper from bash command fixup utilities.
- Removed BashTool's one-time bash-fixup notice tracking and stopped emitting those notices when fixups were applied.
Root cause (verified on user's environment):
- User commit `296641213` swapped status-line's context% computation from cheap `calculatePromptTokens(lastAssistantMessage.usage)` to `computeContextBreakdown(session)`, which walks EVERY message and runs native `countTokens` (~0.5 ms per message).
- The 2-second TTL cache helps for steady-state idle but every cache MISS is a full sweep.
- `updateEditorTopBorder()` is invoked on EVERY agent event (event-controller.ts:163 — `agent_start`, `delta`, `agent_end`, `tool_*`). Each delta during streaming can trigger a cache miss.
- User session has 2,312 messages → each full sweep is ~1,120 ms blocking.
- During streaming the UI freezes for ~1.1 s every ~2 s, producing the user-visible 'jittery rendering' ("버벅거림") and 'status bar disappearing' symptoms.
Fix:
`StatusLineComponent.getCachedContextBreakdown()` (renamed from `#getCachedContextBreakdown` so unit tests can exercise it directly) now uses an incremental per-message token cache that exploits the append-only nature of `session.messages`:
1. Message tokens (the dominant cost): cached per-index. New messages are tokenized as they arrive; previously-cached messages are reused. The LAST message is always recomputed because its content may still be growing during streaming. Compaction (messages.length shrinks) resets the cache.
2. Non-message tokens (system prompt + tools + skills): cached separately, invalidated only when a cheap inputs-identity fingerprint changes (model swap, skill toggle, tool registration). These rarely change during a session.
Required exposing three helpers from `modes/utils/context-usage.ts` (`estimateSkillsTokens`, `estimateToolSchemaTokens`, `computeNonMessageTokens`) so the status-line cache can call them directly.
Performance (2,300-message synthetic session, measured on user's M-series Mac):
- COLD warm-up call: ~75 ms (one-time, runs at OMP startup before any streaming)
- WARM refresh, no new message: ~0.04 ms (20 calls = 0.7 ms total)
- WARM refresh, 1 new message: ~0.02 ms
vs. prior implementation:
- Per cache-miss call: ~1,120 ms blocking
- 28,000× speedup on warm-state refresh
`computeContextBreakdown` itself is untouched — `/context` slash command continues to use it, and its output matches the status-line context% for the same session state (parity preserved).
Tests: 6 new cases in `packages/coding-agent/test/status-line-context-cache.test.ts` covering cold/warm/append/compaction/non-message-invalidation/zero-messages and a perf smoke test asserting 20 warm refreshes on a 200-message session complete in <100 ms.
Full suite: 3,199 tests, 26 pre-existing failures (status-line accent / log_experiment timing-flaky / skills / github tool / workspace-tree / tool path — all unrelated and baseline-confirmed). Lint: 1 pre-existing import-order issue in `event-controller-plan-ready.test.ts` unchanged.
Status-line's context_pct segment was computing tokens via
calculatePromptTokens(lastAssistantMessage.usage), which sums input +
cacheRead + cacheWrite from the Anthropic API usage object. The /context
slash command is computed by computeContextBreakdown, an offline estimate
over the live session state (systemPrompt + tools + skills + messages).
Both numbers are correct under their own definition, but they can
diverge by 2x+ on the same session when a turn rotates cache tiers
(e.g. 5m → 1h ephemeral re-cache) and cache_creation_input_tokens spikes.
Users read the two surfaces as one consistent dashboard and treat the
mismatch as a bug.
Repro: same session at the same moment reports 212K (21.2%) in /context
and 44.2%/1M in the status line — ~230K gap driven by per-turn
cache_creation on a system-prompt boundary.
This change makes status-line use the same computeContextBreakdown
source as /context so both surfaces stay consistent. The breakdown
result is cached with a 2s TTL inside the component so the per-frame
status-line render does not re-walk every message via
estimateMessagesTokens on long sessions. The Anthropic API per-turn
prompt size remains observable via existing token_in / cache_read /
cache_write / token_total segments.
- New 'usage' status-line segment showing Anthropic 5h/7d quota
- Background refresh (5min TTL) via fetchUsageReports
- thinking.max symbol added to UNICODE_SYMBOLS
Personal patch consolidated into branch.
Bug: Ctrl+C on the ask tool selector threw ToolAbortError, the turn
ended with stopReason === "aborted", and handleBackgroundEvent fired
sendCompletionNotification() unconditionally — producing a misleading
"Task complete" desktop toast for a turn that never actually completed.
Fix mirrors the stopReason filter already used by
#currentContextTokens, #handleMessageEnd, and the retry / TTSR /
compaction skip paths across agent-session.ts: check the most recent
assistant message via session.getLastAssistantMessage() and return
early when stopReason is "aborted" or "error".
Test coverage (event-controller-abort-guard.test.ts, 6 cases):
- aborted -> 0 sendNotification calls
- error -> 0 calls
- stop -> 1 call (normal completion)
- no last assistant message -> proceeds (defensive)
- isBackgrounded=false (foreground) -> still 0
- completion.notify=off -> still 0
Matching guard applied to the standalone desktop-notify extension
(~/.omp/agent/extensions/desktop-notify/index.ts) which is currently
the live producer of completion toasts after Phase 1 of
seed_0ca7e1143ac1.
