- Normalized agent `setSystemPrompt` to wrap string inputs into one-item arrays.
- Updated session creation to accept string `systemPrompt` values and normalize callback or direct results to string arrays.
- Adjusted extension result handling and test fixtures to accept string `systemPrompt` and missing `assistant_message` fields without crashing.
- agent-loop: raise repetition-detection floor to 180 chars and clear thinking
replay anchors when collapsing a detected loop.
- providers/google: ignore empty text parts, retain terminal thoughtSignatures,
and stop function-call signatures clobbering the prior block.
- autolearn: capture goal-mode at the turn boundary; harden managed-skill writes
against hard-links/symlinks (O_NOFOLLOW + nlink); refuse minting managed skills
whose name an authored skill already claims.
- eager tasks: thread agentKind through the session so a custom top-level agentId
still gets always-mode delegation; split Eager Tasks prompt into hard vs soft.
- title-generator: race the online title model against a local tiny-model fallback.
- eager-todo: keep the soft reminder aligned with the todo init schema.
- mcp/stdio: keep close() detaching the read loop instead of awaiting it.
- stream loop: fix collapsing and tool-call thought-signature handling.
- Validated queued toolChoice against active tools in agent and coding-agent sessions.
- Rejected queued forced choices with reason "unavailable" when selected tools were inactive.
- Dropped provider toolChoice payloads when requested function tools were not offered.
- Probed Tokio worker-thread support and fell back to current-thread runtime creation.
- Replaced queued-message interrupt flow with session abort calls on empty submit and escape.
- Removed interrupting state and notifyInterrupting teardown paths from abort handling.
- Updated AgentSession queue operations to use shared steering and follow-up queue views.
- Propagated isAborting through session state and collab payloads to suppress late updates.
- Coalesced concurrent interruptAndFlushQueuedMessages() calls through one in-flight promise.
- Replaced continue()-retry logic with agent.prompt() to flush queued messages from empty contexts.
- Skipped queued-message flush replay while compacting or streaming to avoid turn overlap.
- Updated flush path to consume queued steering first, then follow-ups, via dequeuing helper.
- Added a regression test for empty-state interrupt-and-flush delivering queued steers safely.
- Replaced unknown model contextWindow/maxTokens sentinels with nullable values across types and catalog data.
- Mapped request token calculations to treat null maxTokens as unlimited output caps.
- Updated remote compaction and context checks to ignore unknown limits by using Infinity/0 fallbacks.
- Adjusted CLI/model registry flows to skip cap enforcement for null limits and render unknown values as '-'.
- Added `REMOTE_COMPACTION_TIMEOUT_MS` and wrapped remote compaction fetch signals with a timeout-backed `AbortSignal` to prevent indefinite hangs.
- Extended `requestOpenAiRemoteCompaction` and `requestRemoteCompaction` options with `timeoutMs` so callers can customize or rely on the new default watchdog.
- Optimized `trimOpenAiCompactInput` by caching serialized item sizes and decrementing a running budget as entries are removed, avoiding repeated JSON re-stringification.
- Replaced Azure and OpenAI provider calls with `postOpenAIStream` flow.
- Fixed stream error handling by retaining status, headers, and body on failures.
- Fixed stream parsing by handling raw JSON SSE frames and `[DONE]` events.
- Added `OpenAIHttpError` with parsed messages and timeout-aware retry behavior.
- Added remote-compaction tests for timeout, abort, and 500-fallback behavior.
- InputController now dispatched Esc to active viewSession operations, aborting compaction, handoff, and retry directly.
- Removed competing onEscape handler swaps across command and event controllers so overlapping auto/manual flow events no longer overwrote cancellation callbacks.
- Compaction now propagated fetch options and rethrew aborted signals so cancellations were not treated as remote failures.
- Re-polled steering at the loop yield boundary and included it in the pre-stop pending batch so late messages are processed immediately.
- Added session-side draining for stranded queued messages, scheduling an auto-continue when a prompt settles and follow-ups or steers remain.
- Added a regression test for late steering injection at yield and updated mid-turn collab prompt handling to keep steering messages in the pending display queue until consumed.
- Added optional `useless` flags to tool result types and payload builders.
- Added `pruneUseless` and `dropUeless` options to control uneventful result pruning.
- Changed compaction and shake passes to prune or ignore non-error useless tool results.
- Changed conversation serialization to omit useless toolCall/toolResult pairs from output.
- Added coverage for useless tagging, pruning, and serialization behavior.
- Added `hasSteeringMessages` to `executeToolCalls` polling so queued steering is detected without dequeuing.
- Retained fallback to `getSteeringMessages` by consuming messages when no peek callback exists.
- Updated run-summary test mocks to track tool completion and only surface steering messages after the first task finishes.
- Reworked steering message retrieval from call counts to completion-and-drain state so pre-chat polls no longer block tool execution.
- Revised task prompt guidance to require batching multiple `tasks[]` in one call when subagents share context.
- Added optional `hasSteeringMessages` config hook and limited steering checks to boundaries.
- Fixed interrupted tool-batch steering by keeping queued messages until boundary handling.
- Added idle text and image submissions to steer queueing when no input waiter exists.
- Auto-continued resumable sessions after queued steering and preserved submit metadata.
- Renamed all functions, types, and constants in @oh-my-pi/snapcompact to namespace-relative names (`snapcompactCompact` → `compact`, `renderSnapcompactFrames` → `renderMany`, `snapcompactFrameCount` → `frames`, `SnapcompactShape` → `Shape`, `SNAPCOMPACT_SHAPES` → `SHAPES`, …).
- Converted every consumer to `import * as snapcompact` member access: `agent/compaction.ts`, `coding-agent` `agent-session.ts`/`session-manager.ts`/`snapcompact-inline.ts`, and all affected tests.
- Renamed internal `geometry` locals to `geo` in `snapcompact.ts` to avoid TDZ collisions with the new `geometry` export.
- Updated `docs/compaction.md` prose and added a Breaking Changes entry to the snapcompact changelog documenting the full rename map.
- Added `renderSnapcompactFrames()` and `snapcompactFrameCount()` to @oh-my-pi/snapcompact for paging arbitrary text into PNG image blocks without dim-marker bookkeeping.
- Widened the agent loop's `transformProviderContext` hook to `(context, model) => Context` so per-request transforms can gate on the dispatch model's capabilities.
- Added `SnapcompactInlineTransformer` rendering the system prompt and large historical tool results as snapcompact frames on vision models: vision gate, per-provider image budgets, 3k-token floor, savings-margin gate, skip-last rule, and hash-keyed render caches swept to live tool calls.
- Added default-off `snapcompact.systemPrompt` and `snapcompact.toolResults` settings under a new Context → Experimental group, composed after secret obfuscation in `sdk.ts` so frames are built per-request and never persisted to session.jsonl.
- Added prompt stubs (`snapcompact-system-stub.md`, `snapcompact-system-frames-note.md`, `snapcompact-toolresult-note.md`) and unit tests covering frame paging, no-mutate guarantees, budget caps, gates, and render caching.
- Mapped Codex `end_turn:false` terminal events to `pause_turn` stop details in response stream parsing.
- Updated `agent-loop` to re-sample `pause_turn` turns, reset on tool calls, and cap continuations at 8.
- Added coverage for pause-turn mapping and continuation-capping in agent and AI stream tests.
- Extended `AgentTool.concurrency` to accept per-call resolver functions and resolved concurrency mode from each tool call, falling back to exclusive on resolver errors.
- Updated BashTool to schedule non-PTY calls as shared and PTY calls as exclusive so non-interactive bash calls can run in parallel within one message.
- Tracked in-use persistent shell sessions in the bash executor and routed overlapping calls on the same session key to isolated one-shot shells while preserving owner session availability.
The shake-strategy post-shake threshold check was reading
#estimatePendingPromptTokens([]) while #checkCompaction triggered on
calculateContextTokens(assistantMessage.usage). The local estimator
ignored block.thinkingSignature payloads (OpenAI Responses encrypted
reasoning items, Anthropic signed thinking blocks, etc.), so on a
thinking-heavy session the estimate sat ~0.9–2× below provider-reported
usage. Once the two straddled the threshold, the #2119 dead-loop guard
never fired, shake reported 'handled', and #scheduleAutoContinuePrompt
re-injected the auto-continue developer prompt every turn — 53 injections
in a real 25-minute repro session before an external timeout.
Thread the trigger's provider-anchored contextTokens through
#runAutoCompaction → #runAutoShake for the threshold and incomplete
paths, then evaluate residual pressure as triggerContextTokens −
result.tokensFreed with an 80% recovery-band hysteresis. Re-checking
against the raw threshold (even on the corrected metric) would still let
shake reclaim a trickle of the previous turn's elidable blocks and land
just under the line every turn; the band closes that oscillation.
As defense in depth, estimateTokens() now charges thinkingSignature and
redactedThinking.data alongside the visible thinking text so every
other site that uses the estimator (idle compaction, pre-prompt check,
status line) tracks provider usage on replay.
New regression test pins the contract; existing dispatch test bumped
its mocked tokensFreed so its happy-path scenario lands inside the new
recovery band.
Fixes#2275
- The `snapcompact-summary.md` prompt was removed from `packages/agent` to further centralize `snapcompact`-related concerns within the dedicated `@oh-my-pi/snapcompact` package.
- Introduced `isSnapcompactShape` for runtime validation of `SnapcompactShape` overrides, enhancing data integrity when loading configuration from dynamic sources.
- Updated README and native module comments to reflect the standalone `snapcompact` package structure.
- Added a new @oh-my-pi/snapcompact package and redirected compaction call sites to it.
- Added provider-aware snapcompact shape resolution for model-specific mixed-frame behavior.
- Added optional image detail support by extending ImageContent and passing hints through OpenAI providers.
- Added native snapcompact render options, including 5x8/8x8 font loading and palette/geometry controls.
Interrupting mid-tool execution (e.g. Enter with a pending steer) drained the steering queue into the dying run — it landed in history without a response and the post-abort resume saw an empty queue, so the agent stopped instead of continuing. Steering/follow-up/aside queue polls in runLoopBody and the post-tool-call check in executeToolCalls are now skipped once the run's abort signal fires, leaving the queue intact for Agent.continue().
Adds snapcompactCompact() in compaction/snapcompact.ts: instead of an LLM-generated summary, discarded history is printed onto dense 2576px PNG frames with the public-domain X.org 5x8 pixel font and re-attached to the compaction summary message as image blocks. Fully local — no model call; ~7x cheaper than raw text at near-parity recall. CompactionSummaryMessage now charges per attached frame in estimateTokens(), frames persist under preserveData.snapcompact with an 8-frame budget that evicts middle-out (session-head frame pinned so head and tail both survive). Rasterization and PNG encoding run in native code via renderSnapcompactPng().
