- Add `setPromptDropped` hook and `DroppedPrompt` type to return prompts that were cancelled during turn setup before dispatch.
- Restore dropped prompt text and image attachments to the interactive mode editor and remove the optimistic transcript row.
- Implemented the `ctok` Rust native tokenization engine with offline support for Claude V3, V47, V5, and V5Sonnet families.
- Replaced global token estimation with model-scoped `Tokenizer` instances and provider-anchored transcript accounting across packages.
- Added vocabulary generation scripts, test fixtures, and comprehensive unit tests for tokenizer routing and matching modes.
getContextBreakdown used message position (anchorIndex >= pending.cutoffCount) as a proxy for usage freshness. After a mid-run compaction rebased the in-flight snapshot, an in-flight provider response whose request predated the compaction landed past the rebase cutoff carrying pre-compaction usage, so it out-ranked the rebased estimate and reported the pre-compaction token count (~2.6x the real one). That phantom overflow tripped the "freed too little context to make progress" guard and drove the frame-rescue path on a byte-identical tokensBefore.
Assistant context snapshots now carry a monotonic compaction epoch, bumped in rebaseAfterCompaction and stamped at message-record time. A post-cutoff anchor whose epoch predates the pending snapshot's epoch is no longer trusted over the rebased estimate.
Fixes#8887
A boolean latch survived /new and unnamed session switches, so the
replacement session skipped titling and could inherit the previous
skill's title. Bind the latch and the apply check to the originating
session id.
maybeStartTitleGeneration used to fire again for every untitled skill
prompt, so a queued /skill: during the first title request could race
and rename the session. Latch until the first request settles.
Session titles ignored /skill:<name> <args> because the invocation is a
custom skill-prompt, not a user turn. Feed the chip or reconstructed
/skill line into first-title generation and replan context, never the
expanded SKILL.md body.
Mirrored registry status from pre-wire session run-state transitions and required live session corroboration before a peer can sustain bare hub waits.
Fixes#8634
A user-invoked /skill:<name> reaches the session as a user-attributed skill custom message (role custom, attribution user) whose expanded SKILL.md body is the task prompt. The auto-thinking gate in #promptWithMessage only accepted role === "user", so these turns skipped classifyDifficulty/applyAutoThinkingLevel and the effort stayed stuck on pending auto.
Broaden the gate to also accept user-invoked skill prompts via the now-exported isUserInvokedSkillPrompt helper; agent-originated and autoload skill injections stay excluded.
Fixes#8554
Address review: #checkpointState is now assigned in the pre-await section alongside the reminder append, so a model that calls rewind immediately after seeing the notice finds an active checkpoint instead of 'No active checkpoint'. The entry id is backfilled post-await once the checkpoint toolResult entry is persisted; #applyRewind runs on a later rewind turn, never before the backfill.
Move the per-request date/cwd line out of the system prompt into a
first-turn system-reminder so open-weight providers keep their tool-schema
prefix cache; the reminder refreshes itself at midnight. Closes#7404.

Address review: move the reminder text into a static prompt file rendered via prompt.render (no inline prompt strings); append it to agent.state synchronously before any await in the message_end handler so the next provider call within the same tool loop always sees it; persist it via the interrupted-thinking pattern; locate the checkpoint entry by message identity since the reminder entry now follows it; collapse the rewind tool description to one line (the MUST-rewind rule lives in the notice).
Move the rewind instruction out of the permanent checkpoint tool result into a transient post-checkpoint notice that is branch-cut away on rewind; rewrite the rewind-report prompt forward-looking (no negation); collapse the rewind tool description to one line. Closes#8499.
Reparent service-tier metadata before removing discarded empty turns. Persist a branch marker for content-bearing children so reload never selects the discarded subtree.
Fixes#5179
Empty assistant stops were reparented off the active leaf in memory only. The session loader rebuilds the active branch from the last physical journal entry, so a capped empty stop (or one killed mid-retry) resurfaced as the active leaf on reload. Added SessionManager.dropLeafEntry to physically remove the entry and rewrite the file, and route every empty-stop discard through it.
Fixes#5179
Kept the Bun event loop live across subagent yield drains and delayed parent result flushes. Added a timer-lifecycle regression for the idle flush.
Fixes#8462
Expose the Pi-compatible tui, rpc, json, or print host mode to every extension context and cover mode transitions in the runner regression suite.
Fixes#8419
- Replaced blanket subagent advisor global settings with fine-grained per-agent configuration and frontmatter support.
- Added dashboard keybindings and inline override editors for managing agent advisor patterns.
- Implemented settings migration logic to convert legacy global options into per-agent settings.
- Updated session persistence and execution layers to restore and enforce per-agent advisor behaviors.
- Added a 60-character minimum length threshold for demoting interrupted thinking into hidden continuity context in agent-session.ts.
- Updated LLM message conversion in messages.ts to strip incomplete thinking from user-interrupted assistant turns regardless of continuity note presence.
- Added test coverage in agent-session-interrupted-thinking.test.ts verifying behavior for reasoning lengths below and at the threshold.
Clear the scheduled marker when the queued-message continuation claims its run so later idle steers and follow-ups can schedule another drain.
Add coverage for two successive successful idle drains.
Fixes#8326
Replace the resettable queued-message block with a nested mode-exit suppression depth that steer and follow-up queueing cannot clear.
Cover a steer arriving after abort settles but before Vibe teardown releases.
Fixes#8326
abort()'s stranded-queue drain could restart a queued user turn on the still-live Vibe tools before teardown removed them. Run the exit teardown with the queued-message drain suppressed, then re-arm it so the queued turn resumes as a clean non-Vibe turn.
Fixes#8326
