- 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.

- Updated test suites to use renamed generic discovery methods and removed back-compat test coverage for legacy MCP shapes.
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.
ImmutablePrefix caches system prompt + tool specs after first build()
so subsequent turns reuse identical byte sequences. AppendOnlyLog
converts messages once via syncMessages() and only appends deltas
on further turns — prior-turn bytes stay stable.
- New module: packages/agent/src/append-only-context.ts
StablePrefix, AppendOnlyLog, AppendOnlyContextManager
- AppendOnlyContextManager added to AgentLoopConfig
- Wired into streamAssistantResponse in agent-loop.ts
- Toggleable via provider.appendOnlyContext setting (auto/on/off)
- Default auto enables for deepseek provider
- 38 tests covering prefix, log, sync, compaction handling
- /session info surfaces current active state
Keep chat notifications emitted during session_start visible after the initial transcript render rebuilds the chat container. Add regression coverage for preserving startup notifications during initial render.
Fixes#1316
When session.prompt() returns, idle-flush tasks for async-job result
deliveries are scheduled via #schedulePostPromptTask (1ms delay) and
added to #postPromptTasks immediately. The 800ms loop timer could fire
in that window before isStreaming became true, causing the loop to
submit the next prompt while the delivery turn was still pending. The
delivery then hit AgentBusyError and the job result was silently dropped.
Add AgentSession.hasPostPromptWork (= #postPromptTasks.size > 0) and
include it in #isLoopAutoSubmitBlocked() alongside isStreaming and
isCompacting. Add a regression test that verifies the loop defers when
hasPostPromptWork is true and fires once it becomes false.
Fixes#1294
Allowed /goal set to replace the current active goal instead of rejecting and discarding the command input.
Added goal runtime and interactive-mode regression coverage for active replacements.
Fixes#1293
- Added a shared `interruptHint()` utility in the modes shared module to generate the interrupt suffix with themed bracket glyphs.

- Updated interactive mode to render the loader spinner with the current working message accent when available.
- Added a fallback to theme accent and a reset color code when no working-message accent is provided.
- Loading message rendering now derived session-specific accent colors and applied them to shimmer output when a session name was available.
- Shimmer palettes were updated to accept raw ANSI color values as well as theme color names during compilation.
- A unit test was added to confirm shimmer text rendered with a supplied ANSI crest color.
- Added SettingsList#setItems to replace items and clamp selection to a valid index after updates.
- Updated SettingsSelector to rebuild active memory items on backend changes and skip refresh when appropriate.
- Switched MCP wizard and command spinners to theme frames with themed initial frame and 80ms updates.
- Reworked welcome intro animation for a 3-second eased sweep with optional shine blending.
- Added memory backend refresh tests and aligned package changelogs with the updated behavior.
- Added optional `onBeforeYield` configuration and `setOnBeforeYield` in Agent, executed before follow-up checks.
- Added `YieldQueue` to `AgentSession`, with setup/teardown and streaming/idle flush via `setOnBeforeYield`.
- Replaced immediate async-result follow-up dispatch with queued batch entries, including stale-state suppression.
- Added MCP follow-up queueing in SDK, deduplicating updates by `serverName` and `uri`.
- Added changelog entries for `onBeforeYield`, async-result batching, MCP dedupe, and `display.shimmer` modes.
- Added yield queue unit tests for streaming emission, debounced idle batches, stale filtering, and error isolation.
- Added `display.shimmer` setting (`classic`, `kitt`, `disabled`) with default `classic` and UI metadata.
- Added shimmer mode resolution with defaulting plus classic/KITT intensity tier profiles and thresholds.
- Added `getFgAnsi` handling across shimmer compilation and progress-bar themes, with fallback ANSI output defaults.
- Reworked shimmer rendering to coalesce same-tier segments, cache palettes by symbol, and map disabled mode to mid-tier.
- Tuned loader timing to a 16ms render interval and 80ms spinner stepping for smoother ~60fps updates.
- Added configurable shimmer palettes by introducing ShimmerPalette and ShimmerSegment types.
- Added a new shimmerSegments helper to render a single sweep across multiple text segments with optional per-segment palettes.
- Updated working-message rendering to style the interrupt hint using a separate borderAccent palette.
- Added a new shimmerText helper that computes a moving accent shimmer band across characters.
- Updated the interactive mode loader and slash-command ASCII bar renderer to use shimmer styling, with interrupt hints kept dim.
- Added tests for shimmer-enabled progress rendering and verified the visible bar output remains correct.
- get op now returns paused goals (was returning null when enabled=false)
- complete op now works on paused goals; previously required enabled=true
which always failed after an interrupt set enabled=false
- create op now allowed after previous goal status is 'complete'; was
incorrectly blocked by the same guard as 'dropped' check
- goal tool is re-added to the active tool set on session reload when a
paused/active goal is persisted to disk; sdk.ts:1599 excludes 'goal'
from initial active tools unconditionally, so restoreModeFromSession
now re-adds it and saves #goalModePreviousTools for later cleanup
- goal_updated event for 'dropped' status now triggers #exitGoalMode
before clearing goalModeEnabled, ensuring the previous tool set is
restored when the agent drops a goal via the tool
- added 'resume' and 'drop' ops to goal tool schema and execute path
- updated goal.md prompt to document new ops and the paused-goal workflow

- Updated loop iteration flow to defer next prompts while the session is streaming or compacting.
- Added tests verifying loop submissions wait until compaction/streaming completes before resolving.
