- Updated skill invocation cards with home-shortened paths, dynamic line count units, and compact invocation argument display.
- Unified branch summary styling with compaction banners to provide a consistent visual language for history collapse points.
- Removed leaked absolute home directory paths from skill metadata displays.
- Swapped legacy `zodToWireSchema` for `toolWireSchema` to normalize tool schemas.
- Updated `getSchemaPropertyKeys` in `tool-index.ts` to process schemas via `toolWireSchema`.
- Refactored tool token estimation in `context-usage.ts` to utilize the new schema helper.
- Fixed ArkType assertion checks in test helpers to correctly verify instances against `arkType.errors`.
- Aligned test suites and mock specifications with raw schema-based parameters instead of manually stringified JSON structures.

- Anchored context usage calculations on assistant snapshots and computed percent numerically.
- Updated status-line, /context, selector, and interactive mode flows to share session usage totals.
- Extended status-line cache fingerprinting and invalidation for assistant usage and prompt/tool/skill changes.
- Created AdvisorRuntime and AdviseTool to drive a read-only advisor agent that delivers severity-tagged advice (nit, concern, blocker) with interruption policy and transcript delta rendering.
- Added /advisor slash command with on/off/status/dump subcommands to control advisor lifecycle and inspect advisor metrics (model, messages, tokens, cost).

- Added canonicalizeMessage tests for undefined, blank, whitespace, and dot-only inputs.
- Removed the streaming guard that previously rejected /tan while the parent response was still generating.
- Passed "deliverAs: \"nextTurn\"" when sending the background dispatch breadcrumb and kept "triggerTurn: false" so an in-flight turn is not steered.

With display.showTokenUsage on, the usage row was rendered inside the
assistant block above the turn's tool blocks. Finalizing the assistant
block was therefore deferred, and the late append recommitted the
already-committed tool rows, duplicating them in scrollback (worst with
parallel tool calls).
The assistant block now always finalizes as soon as a tool-call appears,
and the usage row is emitted as a standalone finalized block below the
turn's tool blocks across all three render paths (live event-controller,
transcript rebuild, agent-hub). The now-dead setUsageInfo/#usageInfo path
on AssistantMessageComponent is removed.
- 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.
- 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.
- Added snapcompact.shape setting with auto and variant options in agent config.
- Implemented resolveShape support for forced variants, auto provider winners, and repricing.
- Threaded resolved shape into compaction and inline-image flows for pricing and rendering.
- 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.
- Fixed `/dump` output (`session-dump-format.ts`) and the RPC `get_state` `dumpTools` payload (`rpc-mode.ts`) serializing Zod schema instances — leaking `def`/`shape` internals and stringified methods — by converting parameters through `zodToWireSchema` like providers receive.
- Fixed context-usage token estimation stringifying the Zod `def` tree, which overcounted tool schema tokens in the status line.
- Fixed tool-discovery indexing (`tool-index.ts`) returning empty `schemaKeys` for Zod tools, weakening BM25 ranking; keys are now recovered via wire conversion.
- Fixed the extension inspector panel rendering "(no arguments)" for Zod tools by reading properties off the converted wire schema.
- Added coverage in `tool-index.test.ts` plus new `context-usage.test.ts` and `session-dump-format.test.ts`, and a changelog entry.
A subagent's send await:true to Main during a blocking task spawn was a structural deadlock: deliverIrcMessage queues mid-turn messages as step-boundary asides, but Main's next boundary requires the sender's own batch to finish, so the sender always burned the full irc.timeoutMs. Awaited sends now pass expectsReply through IrcBus.send; a mid-turn recipient with async.enabled off generates an ephemeral no-tools reply via runEphemeralTurn, records an irc:autoreply aside in its own history, and delivers it back over the bus with replyTo threading so the sender's waiter resolves.
- Added an exported `createIrcMessageCard` renderer to `tools/irc.ts` for incoming and relay IRC traffic.
- Updated IRC message rendering in `UiHelpers` to use the shared card component instead of manual transcript block construction.
- Included `replyTo` and timestamp-derived age metadata in the IRC transcript card output.
A job poll whose watched jobs are all still running and nothing was cancelled is pure 'still waiting' noise once a newer block exists. ToolExecutionComponent now detects isWaitingPollDetails on the result, leaves the block displaceable, and keeps its rows out of scrollback. EventController tracks the most recent displaceable poll and resolves it (sealing the block) on every event that proves another tool now owns the live region: a new tool call/result, a streaming arg start, an end-of-turn signal, or another job result that itself isn't displaceable. UiHelpers' transcript rebuild applies the same rule. Docs and the new job-poll-displacement test pin the behavior.
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.
app.clipboard.pasteImage dead-ended with a status message when the
clipboard held text, which made the chord useless on hosts that only
deliver that one keypress (VS Code's integrated terminal forwarding
Ctrl+V, Windows clipboard history via Win+V simulating Ctrl+V).
- handleImagePaste now pastes clipboard text through the editor's
paste semantics when no image is available; an empty clipboard
reports 'Clipboard is empty'.
- readTextFromClipboard reaches the Windows clipboard through host
PowerShell under WSL (mirroring readImageFromClipboard), with CRLF
normalization and UTF-8 output encoding.
- handleClipboardTextRawPaste's empty-clipboard status message moved
to the actual empty branch (was shown after successful pastes).
- Clipboard reads are constructor-injectable for tests.
