- Add watchDirConfig() for per-directory config watching
- Register watchers for subdirectories with their own dispatch.toml
- Fix permission ordering: move "*" wildcard to front so findLast
reaches specific rules first (was silently breaking all specific
bash permission rules)
- Add comprehensive tests for watcher functionality
- Update mocks in test files
|
|
Load an optional global config at ~/.config/dispatch/dispatch.toml
(override via DISPATCH_GLOBAL_CONFIG) and deep-merge it underneath every
project/working-directory dispatch.toml, so machine-wide settings — most
notably globally available LSP servers — work in any repo without per-repo
config. Local always wins on conflicts.
- loader: add getGlobalConfigPath(), loadGlobalConfig(), mergeConfigs();
loadConfig(dir) now loads+merges global. [lsp] and [[keys]] merge by id;
[permissions] merge per-group with global patterns emitted first so local
rules win at evaluation time (findLast). A malformed global config is
downgraded to empty rather than breaking every repo.
- watcher: watch BOTH global and local dispatch.toml so hot-reload re-merges
on either change (dedupes when paths coincide).
- export new loader fns from config/index and core index.
- types/agent-manager: doc updates reflecting merged LSP resolution.
- dispatch.toml: document global-default merge behavior; activate biome and
typescript-language-server LSP entries.
- tests: merge precedence, lsp/keys merge-by-id, permissions merge,
filesystem integration, malformed-global resilience; isolate global path
in existing loader tests.

Root cause of the 'first warmup misses' + 'switch to chat misses' bugs:
Anthropic keys the MESSAGE-level prompt cache on `tool_choice` AND the
extended-thinking parameters (both rows in their cache-invalidation table mark
the messages cache as invalidated on change). The original warmCache() sent
toolChoice:'none' and NO thinking providerOptions, while real turns send
toolChoice:'auto' + thinking config for the effort. So warming and chat wrote
TWO different message-cache buckets:
- warmup #1 missed (no warm-only bucket existed yet), every later warmup hit
its own bucket;
- the next real chat message read the OTHER bucket → miss.
Fix: extract a shared buildStreamOptions() that produces the cache-affecting
params (toolChoice + thinking providerOptions + maxOutputTokens). Both run()
and warmCache() now call it with the SAME resolved reasoning effort, so the
warming replay refreshes the exact cache the next real message reads. The
trivial probe turn is still appended AFTER the last cache breakpoint, so it
never disturbs the cached prefix.
Threaded the per-tab reasoning effort (per-model -> per-tab selector -> default,
mirroring processMessage) from the frontend resolver through POST /chat/warm to
warmCacheForTab to warmCache.
Tests: updated the warmCache toolChoice test to assert it MATCHES a real turn,
added an invariant test driving run() and warmCache() and asserting identical
cache-affecting params, and assert effort forwarding in the frontend store.
check / test (780) / frontend build / typecheck all green.

Keep a tab's provider prompt-cache warm while idle by periodically replaying
the exact cached conversation prefix plus a single trivial throwaway turn,
resetting the provider's ~5-min cache TTL so the user's next real message hits
a warm cache.
Backend:
- Agent.warmCache(history): extracts buildLlmContext() shared with run(), then
re-sends the identical system+tools+history prefix (same Anthropic
cache_control breakpoints) plus a 'reply with just a .' probe turn via
toolChoice:none. Returns the request usage; mutates no history, emits/persists
nothing.
- AgentManager.warmCacheForTab(): resolves the same agent the next real turn
would use, replays the FULL genuine history, refuses while a turn is running.
- POST /chat/warm: returns ONLY the warming request's usage (never persisted,
never folded into the real usage aggregate).
Frontend:
- cache-warming.svelte.ts store: per-tab 4-min repeating idle timer with
countdown, warming-specific last-request cache %, and error capture. Arms on
turn end, pauses during a turn, disables+resets on a real user message.
- cache-warm-storage.ts: per-tab localStorage persistence of the toggle.
- Lifecycle hooks wired into tabs.svelte.ts (status/statuses/sendMessage/
hydrate/create/open/close).
- ModelSelector: bottom-of-panel checkbox + debug strip (last-% / countdown /
error), shown only when enabled. Warming cache data never touches the real
Cache Rate view.
Tests: core warmCache (5), api warm route (3) + warmCacheForTab (3), frontend
store (12) + storage (10). check / test (779) / frontend build / typecheck all
green.

Summarize a conversation's older "head" into a structured anchored Markdown
summary while preserving the most recent turns verbatim, shrinking context size
while keeping the information needed to continue coherently. Triggered by a
"Compact conversation" button in Chat Settings (not an agent tool).
Approach informed by OpenCode's session/compaction.ts:
- Ported SUMMARY_TEMPLATE (Goal / Constraints / Progress / Key Decisions /
Next Steps / Critical Context / Relevant Files) and the anchored-summary
buildPrompt (re-summarizes a prior summary when present).
- Ported the TOOL_OUTPUT_MAX_CHARS (2000) cap on tool results in the summary
request.
- Simplified tail selection to a fixed recent-turn count (DEFAULT_TAIL_TURNS=2)
instead of OpenCode's token-budget splitTurn.
core:
- New src/compaction/ module (pure, DB-free): template, prompt builder,
head/tail selection, transcript renderer with tool-output capping, prior
summary extraction. Generic over ChatMessage so callers keep turnId/seq.
- db/chunks.ts: rekeyChunks(from,to) relocates a tab's full history to a
backup tab (reversible — nothing is deleted).
- AgentEvent: compaction-started / -complete / -error variants.
api:
- AgentManager.compactTab(tempTabId, sourceTabId): side-effect-free
resolveConnection() for the compactor model (configured compaction_model_*,
else the source tab's own key+model), one-shot tool-less summary generation
via a transient Agent, then relocate full history to a fresh backup tab and
re-seed the canonical source id with [summary turn + preserved tail]. Source
tab is locked (messages queue) during the run; queue drains afterward.
- Routes: POST /tabs/:id/compact, GET/PUT /tabs/settings/compaction-model.
frontend:
- "Compact conversation" button in ModelSelector (Chat Settings), between
Working Directory and the agent toggle; idle-gated.
- Compaction-model key+model selector in Settings, beside the title model.
- Transient placeholder tab shows a large, non-faded "Please wait, compacting
conversation…" screen; closing it cancels. Source input locked while running.
- Handle compaction-* events: reload compacted source, insert backup tab,
refocus source, discard placeholder.
tests: core compaction unit tests, rekeyChunks DB test, AgentManager.compactTab
orchestration tests, and compaction route tests. All green (713 tests), biome
clean, all typechecks pass, frontend builds.

Add multimodal image/PDF input to the chat box via clipboard paste, gated by a
graceful per-model capability check.
UX: a pasted image/PDF inserts an inline token (【image:…】 / 【pdf:…】) into the
draft, so attachments have ORDER relative to typed text and can be referenced
positionally. The token is the only handle — deleting it (atomic Backspace/
Delete, or selection overlap) detaches the file; an input-reconciliation safety
net detaches any attachment whose token is no longer intact. No preview strip.
Capability check: resolveModelCapabilities reads models.dev modalities.input
(new GET /models/capabilities, mirrors /context-limit). The input blocks Send
(no tokens spent) only on a definitive 'no'; unknown capability (catalog offline
/ unmapped provider) stays permissive. Attachments require a fresh turn — Send is
blocked while generating and /chat rejects content mid-turn (409).
Attachments are EPHEMERAL: forwarded to the model for the turn via ordered AI SDK
ImagePart/FilePart content, but never persisted (history keeps the text with
[image]/[pdf] markers). Text-only turns serialize byte-identically to before.
Limits (Anthropic-aligned, enforced at paste + re-validated server-side):
PNG/JPEG/WebP/GIF/PDF; image ≤5MB, PDF ≤32MB, ≤20 attachments, ≤32MB total.
core: UserContentPart types, models/attachments validator, capability resolver,
agent.run+toModelMessages thread ordered content. api: /chat content validation +
passthrough. frontend: attachment-tokens helper, ChatInput paste/token/gating,
per-tab staged attachments, App.svelte capability fetch. +44 tests.

Adds an agent-callable `key_usage` tool that reports current usage for
configured API keys so the agent can pick a key with headroom, warn before
hitting a rate limit, and diagnose exhausted-key failures.
Per key it reports: provider, active/exhausted status (with last error +
when it was exhausted), remaining rate-limit headroom and reset timestamp per
window (5-hour, weekly, and monthly where the provider exposes it), and
whether the figures are live or served from cache (with the cache's
last-fetched-from-source time). Supports anthropic and opencode-go keys
(live with cache fallback for anthropic; live scrape for opencode-go).
Optional `key_id` reports one key; omitted reports all.
Hard permission gate `perm_key_usage` (default off): when disabled the tool
is completely removed from the toolset/context. Registered in both the
parent permission-gated path and the child whitelist path, advertised in the
system prompt (TOOL_DESCRIPTIONS), grantable to subagents via the summon
enum, and exposed as a frontend tool-permission checkbox.
To report data freshness, claude.ts gains `getAccountUsageWithSource` +
`ClaudeUsageResult` (live vs cache + cachedAt from usage_cache.cached_at);
the existing `getAccountUsage` now delegates to it, preserving behavior.
Tests: core key-usage tool suite (windows, %-conversion, freshness, exhausted
status, unsupported/unavailable, filtering) + agent-manager perm-gate test.

Add Language Server Protocol integration modeled on opencode's, wired for
this codebase's plain-TypeScript tool/agent architecture.
Core (@dispatch/core):
- lsp/client.ts: LSP/JSON-RPC client over stdio (vscode-jsonrpc) with the
initialize handshake, didOpen/didChange sync, push + pull diagnostics
(textDocument/diagnostic, workspace/diagnostic), and a generic request()
passthrough for hover/definition/references/documentSymbol.
- lsp/server.ts: resolves dispatch.toml [lsp] entries into spawn specs.
Config-driven only — no builtin registry, no auto-download.
- lsp/manager.ts: process-wide LspManager owning client lifecycles, keyed
by root+serverID, lazy spawn + reuse + graceful shutdown.
- lsp/language.ts: extension->languageId map incl. .luau -> "luau".
- lsp/diagnostic.ts: error-only <diagnostics> block formatting (1-based).
- tools/lsp.ts: on-demand 'lsp' tool (1-based coords -> 0-based wire).
- write-file.ts: optional onAfterWrite hook for diagnostics-on-write.
- config schema: validate [lsp] block; DispatchConfig.lsp + LspServerConfig.
API (@dispatch/api):
- AgentManager owns one LspManager; per-working-directory server cache
cleared on config reload; diagnostics appended to write_file results;
'lsp' tool gated by new perm_lsp setting; shutdownAll on destroy().
Config:
- dispatch.toml: documented, commented [lsp.luau-lsp] Roblox example.
Tests: fake-lsp-server fixture + client/manager/server/diagnostic/schema/
tool/write-hook suites, plus an opt-in real-binary luau-lsp smoke test
(auto-skipped when luau-lsp is absent). 652 pass; biome + 3 typechecks green.

Add a dedicated, permission-gated search_code tool that wraps boyter/cs
(code spelunker) — a fast, relevance-ranked, structure-aware code search
engine — giving agents a better default than grep/find for exploratory
'where is X / how does Y work' searches (ranked results, snippets, ~5x
smaller payloads).
- packages/core/src/tools/search-code.ts: createSearchCodeTool factory;
-f json invocation, workdir path containment, graceful missing-binary
handling (DISPATCH_CS_BIN override), readable per-file formatted output.
- Wire-up: export from core; register in agent-manager (both child-whitelist
and parent perm paths) behind new perm_search_code; add to summon catalog
+ tools enum; frontend ToolPermissions + settings.
- Docker: build a patched, statically-linked cs (pinned v3.1.0 commit) in a
golang builder stage and bundle at /usr/local/bin/cs.
- docker/cs/luau-declarations.patch: additive Luau declaration table so
--only-declarations / definition ranking works for Roblox .luau files
(upstream has Lua but not Luau). Applied during the Docker build.
- Tests: new search-code.test.ts (stubbed JSON formatting + live-cs
integration, skipped when cs absent); agent-manager/routes mocks +
perm-gating assertions; loader pass-through.
All tests (596), biome, and tsc (core/api/frontend) pass. cs-builder Docker
stage verified to build and produce a working patched binary.

'arrives on its own')
Matches actual behavior: a peer's reply wakes this tab with a new message in a
later turn. Updated the send_to_tab description (both canReadTab branches), the
delivery-result text (both branches), and the system-prompt one-liner; updated
the test assertion accordingly.
|

Granting only the user-agent (top-level) permission without the
subagent-summon permission left the agent unable to summon user agents:
the whole summon tool was gated behind perm_summon, so perm_user_agent
alone produced no summon tool.
Register summon when EITHER perm_summon OR perm_user_agent is granted.
createSummonTool now takes an independent subagentEnabled flag (mirrors
perm_summon) alongside userAgentEnabled (mirrors perm_user_agent):
- subagent-only -> ordinary subagents, no top_level
- user-agent-only -> spawns ONLY top-level user agents (top_level
forced, background/top_level params dropped, user-agent catalog only)
- both -> unchanged full behavior
retrieve stays bundled with perm_summon (user agents are fire-and-forget).
Adds core summon tests (user-agent-only mode + legacy-default regression)
and an agent-manager summon/user_agent permission-split suite.
|

The send_to_tab guidance previously told the agent it could call read_tab to
check for a reply, but the tab-messaging permissions are split — a tab can
hold send_to_tab WITHOUT read_tab (the exact case in testing). Advertising a
tool the agent wasn't granted is wrong.
Thread a canReadTab flag from AgentManager.buildTabCommToolEntries into
createSendToTabTool (true iff this tab is also granted read_tab). The tool
description and the delivery-result text now only reference read_tab when
canReadTab is true; otherwise they say a reply arrives on its own and to end
the turn. Drop the read_tab phrasing from the static TOOL_DESCRIPTIONS
one-liner (can't be conditional per-tab there).
Also uppercase ONLY in the recipient reply-contract footer for emphasis.
Tests: cover both canReadTab branches for description + result text; assert
ONLY is uppercased.

replies
Two behavioral problems observed once the tools were usable:
1. The SENDER busy-waited for a reply (ran 'sleep 20' / polled) instead of
ending its turn. Tool description, the delivery result text, and the
system-prompt one-liner now say plainly: do not sleep/poll/run commands
to wait; a reply arrives on its own in a later turn (or via read_tab in a
future turn); keep working if there's other work, else end your turn.
2. The RECIPIENT replied to its OWN user in plain text instead of routing the
answer back through send_to_tab. The provenance wrapper now states the
message is from another AGENT (not your user), and that to reply you must
use send_to_tab addressed to the sender's handle — and only if asked, since
it may just be context. A plain text answer reaches only your own user.
Tests updated for the new wording.
|
|
Granted tab-messaging tools were registered in the API tool payload but
buildSystemPrompt built its 'You have access to the following tools' list
by filtering toolNames through TOOL_DESCRIPTIONS, which had no entries for
send_to_tab/read_tab. The model was therefore told it lacked those tools
and refused to use them even when explicitly granted.
Add the two missing TOOL_DESCRIPTIONS entries so the capability list
matches the granted toolset. Add regression tests that capture the
constructed Agent's systemPrompt and assert the tab-messaging tools are
listed when granted (and omitted when not), locking the prompt list to
the schema list so they can't drift again.

Replace the imperative id-based CRUD todo tool (add/update/list/get/remove)
with opencode's declarative whole-list design: a single `todos` param that
replaces the entire list each call. No model-visible ids, no delta reasoning,
no "task not found" spirals.
- core: TaskItem { id, content, status }; statuses pending|in_progress|
completed|cancelled. TaskList.setTasks/getTasks/onChange. New rich
TODO_DESCRIPTION adapted from opencode's todowrite.txt.
- api: TASK_MANAGEMENT_GUIDANCE system-prompt section (from anthropic.txt);
updated TOOL_DESCRIPTIONS.todo. Reload fix: TabStatusSnapshot now carries
per-tab tasks so getAllStatuses rehydrates the panel on reconnect.
- frontend: mirror types; hydrate tasks from snapshot in both restore paths;
upgrade sidebar Tasks panel to render content + all four statuses + progress.
- tests: new core task-list.test.ts (15); updated api TaskList mocks +
getAllStatuses task-snapshot coverage.
bun run check clean; 569 tests pass; all packages typecheck.

Addresses the live-accumulator overshoot a Gemini review surfaced: the
frontend adds every streamed usage event to cacheStats, but a rate-limited
fallback attempt's usage is discarded server-side (never persisted). Live
numbers overshot until a reload re-seeded from the DB aggregate.
Fix: turn-sealed (emitted AFTER the atomic usage-row write) now carries the
authoritative getUsageStatsForTab aggregate. The store REPLACES (not adds)
cacheStats with it every turn — landing the just-sealed turn's usage AND
self-healing any live drift, including the discarded-fallback overshoot. No
extra round-trip (piggybacks turn-sealed); idempotent in the happy path.
- core: add UsageStats type; getUsageStatsForTab returns it; turn-sealed gains
optional usageStats field.
- api: agent-manager reads getUsageStatsForTab post-flush and attaches it to
the turn-sealed emit (try/catch: omit on DB error).
- frontend: turn-sealed handler replaces cacheStats (undefined ⇒ untouched
back-compat; null ⇒ clear).
Tests: frontend reconcile/self-heal/back-compat/null-clear; api turn-sealed
carries aggregate. 509 -> 514 passing; typecheck + biome green.
|
|
Persist usage as invisible type:"usage" chunk rows (side channel):
- core: add "usage" ChunkType + UsageData; exclude usage rows from
getChunksForTab/getTotalChunkCount; add getUsageStatsForTab aggregate
(exported from barrel); defensive skip in groupRowsToMessages.
- api: agent-manager accumulates per-attempt usageRows and flushes them in
the same atomic appendChunks call as the turn's content (discarded on a
superseded fallback attempt). GET /tabs enriches rows with usageStats.
- frontend: hydrateFromBackend seeds cacheStats from usageStats (reload only;
no re-seed on statuses reconnect, so no double-count with live events).
Tests: core DB-backed usage persistence/aggregate; api usage-row-per-event +
fallback discard; routes GET /tabs usageStats; frontend hydrate seed +
no-double-count + live-accumulation-after-seed. 495 -> 509 passing.

Add a per-model/key reasoning effort setting to agent definitions,
surfaced and editable in the Agent Settings page and displayed at a
glance in the model selector views.
- core: single source of truth for effort levels (REASONING_EFFORTS,
DEFAULT_REASONING_EFFORT='high', labels, isReasoningEffort guard);
add 'xhigh' level; AgentModelEntry.effort; xhigh budget=24000 for
classic-thinking Claude; default floor 'high'. Persist/parse effort
in the agent TOML loader.
- api: thread effort through the fallback chain with per-model -> per-tab
-> default precedence; validate /chat + agentModels effort from the
canonical list.
- frontend: effort <select> per model row in AgentBuilder; effort badges
in ModelSelector (agent + subagent chains); Thinking dropdown sourced
from canonical list; per-tab default raised to 'high'.
- tests: +15 (loader round-trip, agent xhigh budget, canonical list +
guard, api precedence, route validation).

A message queued while the agent was mid-turn was only handled if it
arrived DURING a tool batch (injected as a [USER INTERRUPT]). If it
landed after the last tool call — or the turn had no tools — the agent
silently appended it to history and ended the turn with no response, so
it sat there unanswered. This affected both user-queued messages and
agent-queued ones (send_to_tab).
- agent.ts: stop the end-of-turn drain that swallowed trailing queued
messages into history. They now stay on the queue.
- agent-manager: after a CLEAN turn settles, continueFromQueue() drains
the queue and starts a fresh turn to answer it. Skipped on a
user-stopped or errored turn (queue preserved for the next send).
- Loop safety: continuation draws from the existing autoWakeBudget, so a
runaway agent<->agent chain is bounded; human sends refill it, so human
conversations are never throttled.
- dequeueMessages now tags message-consumed with reason
"interrupt" | "continuation"; the frontend collapses continuation-
consumed queued bubbles into the next turn's initiator row (avoids the
linger/dup traps documented in queue-interrupt-reconcile-edge-cases.md).
- Tests: agent (no-swallow + interrupt regression), agent-manager
(continuation, no-op when empty, user-stop preserves queue, bounded
loop), frontend (continuation bubble becomes next initiator).
- wishlist: remove the now-fixed item.

Add send_to_tab / read_tab tools so an agent can message or read another
tab by a git-style short handle (shortest unique prefix of the tab UUID,
min 4 chars), shown in the tab bar.
- core/db/tabs: resolveTabPrefix + shortestUniquePrefix (open tabs only,
LIKE-sanitized prefix matching)
- new tools read-tab.ts / send-to-tab.ts (+ tests) decoupled from the DB
TabRow via a minimal ResolvedTabRef projection
- agent-manager: unified deliverMessage routing (busy -> queue, idle ->
new turn) shared by POST /chat and send_to_tab; agent->agent auto-wake
budget (MAX_AGENT_AUTO_WAKES) to bound ping-pong loops
- summon/loader: send_to_tab + read_tab as grantable tools
- frontend: shortHandleFor + handle badge in TabBar; perm toggles
- notes: tab-comm / user-agents / todo-redesign plans
- chore: biome format fixes (debug-logger, summon.test)

per-chunk eviction
Replace the stored ChatMessage[] with a chunk-native model: tab.chunks (sealed
ChunkRow[]) + tab.live (transient in-flight turn buffer) + derived tab.renderGroups.
This enables per-chunk eviction (trimming WITHIN a large turn) and raw-chunk
pagination (loadOlderChunks), removing the whole-message eviction limitation.
Backend:
- Emit turn-start/turn-sealed around each turn; expose currentTurnId in the status
snapshot. turn-sealed fires after the durable write (status:idle fires before it).
- New GET /tabs/:id/chunks raw paginated endpoint (limit/before).
- Wrap appendChunks in a single SQLite transaction.
Frontend:
- turn-sealed drives a turn-aware reconcile that folds the sealed turn into chunks
while preserving a concurrent newer in-flight turn and pending queued messages;
deferred while the user is scrolled up.
- Stable turn-scoped render keys (${turnId}:${role}:${n}) avoid remount/flash.
Reconcile correctness (three review passes):
- preserve a concurrent newer turn when an earlier deferred reconcile flushes;
- keep optimistic queued user messages (no loss);
- turn-start backfill skips pending queued rows and tags only the turn initiator;
- bind consumed interrupt messages to the in-flight turn so they collapse on seal
(no lingering/duplicated bubble).
Tests: chat-store reconcile/eviction/pagination suite; api chunks endpoint + events.

Replace the message-as-container model with a flat, append-only chunk log.
- chunks table (id, tab_id, seq, turn_id, step, role, type, data_json): one
row per chunk; tool_call (assistant) and tool_result (tool) are SEPARATE
rows linked by callId. Message/turn are derived groupings, not stored.
- chunks/transform.ts: DB-free explode (Chunk[] -> rows) / group (rows ->
messages), shared by backend and the browser frontend.
- Cache fix: toModelMessages segments each turn at tool-batch boundaries into
stable [assistant, tool] pairs per step, so earlier steps serialize
byte-identically across requests (kills the prompt-cache churn).
- agent-manager persists a turn's chunks on seal (once), discarding a failed
fallback attempt's partial chunks; rebuilds agent history from the log.
- GET /messages windows the log by chunk seq then groups; loadMoreMessages
merges a turn split across the window boundary by turnId.
- One-shot migration drops the legacy messages table and clears tabs;
settings/credentials/keys/usage preserved.
Full suite green (317 tests); biome, tsc, and svelte-check clean.

On hosts where /home is a separate filesystem, the dispatch-api service
could start before /home was mounted. The API's first DB access then
failed (EACCES: mkdir '/home/tradam'), Claude account discovery silently
caught the error and left claudeAccounts empty, and -- because discovery
only ran in the constructor -- it stayed empty for the whole process
lifetime. Every Claude message then fell back to the deepseek-v4-flash /
empty-key defaults, producing a 401 'Missing API key' from OpenCode Zen.
Fixes:
- s6 run script waits (capped ~30s) for /home/tradam before exec'ing bun;
passes instantly where /home is on the root filesystem.
- systemd unit gains RequiresMountsFor=/home and After=...home.mount.
- agent-manager re-runs _refreshClaudeAccounts() on config hot-reload and
lazily on an empty cache in the Anthropic path, so a process that lost
the boot race self-heals on the next request instead of staying broken.

AgentBuilder default, SubAgent mode display
- Filter summon tool catalog to is_subagent-flagged agents only
- Return fresh subagent list in error when slug not found
- Add subagent hint to system prompt when summon tool available
- Default is_subagent checkbox to true in AgentBuilder
- Fix tab-created event to include agentSlug and agentModels
- Add SubAgent read-only mode to ModelSelector with model slider
|

- Refresh agent config from API before sending a message so edits
in AgentBuilder (changed keyId/modelId/agentModels) take effect
immediately on existing tabs instead of using stale snapshots
- Broaden isRetryable check to also match 'usage limit' and
'exhausted' so fallback keys are actually tried on quota errors

running in background
Implements the 'background-running agents + restore-layout-on-reopen'
feature. Full design and parallel-implementation plan in
`plan-bg-restore.md`; Gemini code review (SHIP verdict, no findings) in
`report.md`.
User-visible behaviors:
1. Browser-close keeps agents alive. If an agent is mid-stream when
the browser closes / reloads / loses the network, it continues
processing on the backend. (This was already the case in code —
agents run fire-and-forget in app.ts:77-79 — but it was previously
pointless because the UI never restored the tab to receive the
output.)
2. Layout restore on browser reopen. Every tab that existed at the
time the window was closed is restored, in original `position`
order, with full persisted message history. Tabs whose agents
finished while disconnected appear with the completed message.
Tabs whose agents are still running appear streaming live — the
in-flight assistant message is reconstructed from the backend's
in-memory `currentChunks` (sent over the wire on connect) and
accumulates new deltas as they arrive.
3. Explicit tab-close cancels + forgets. Clicking the X still
cancels the agent (existing `stopTab` in DELETE /tabs/:id) and
archives the row (`is_open = 0`), so it is not restored. No
change to that path.
The gap that the implementation closes: previously, App.svelte:onMount
unconditionally called `createNewTab()` with a fresh UUID, ignoring
every existing row in the `tabs` table. Every browser open was a
clean slate. The DB had the conversation history but no way for the
UI to discover it.
Implementation:
• New `TabStatusSnapshot` interface in
packages/core/src/types/index.ts (auto-exported via existing
`export * from "./types"`):
interface TabStatusSnapshot {
status: AgentStatus;
currentChunks?: Chunk[]; // present iff running
currentAssistantId?: string; // present iff running
}
• `agent-manager.ts:getAllStatuses()` rewritten to return
`Record<string, TabStatusSnapshot>` (was
`Record<string, AgentStatus>`). For running tabs only, attaches a
defensive shallow copy of `tabAgent.currentChunks` (the live
streaming array the per-message loop appends to) plus the DB id
of the in-flight assistant message. The defensive copy is the
consumer's to mutate. Idle / error tabs get `{ status }` only.
`GET /status` and the WS `onOpen` snapshot both pick up the new
shape automatically — neither call site changed.
• Frontend mirror of `TabStatusSnapshot` in
packages/frontend/src/lib/types.ts; `AgentEvent.statuses` variant
updated to use `Record<string, TabStatusSnapshot>`.
• New `hydrateFromBackend()` on the tab store
(packages/frontend/src/lib/tabs.svelte.ts). Sequence on app
mount:
1. Bail with 0 if `tabs.length > 0` (hot-reload idempotency).
2. GET /tabs → list of `is_open=1` rows in
`position` order.
3. GET /status → in-flight TabStatusSnapshot map.
4. GET /tabs/:id/messages for each tab in parallel via
Promise.all → persisted ChatMessage[].
5. Build the Tab objects, splicing the snapshot's live
chunks into the in-flight assistant message for every
running tab (two paths: merge into the existing DB row
with matching id, or append a fresh in-flight message
if no row matches).
6. `tabs = restored; activeTabId = restored[0]?.id ?? null;`
Every fetch is wrapped in try/catch so one tab's failure can't
destroy the whole restore pass.
• WS `statuses` handler in `tabs.svelte.ts:handleEvent` rewritten
for the new shape. Still fires `reloadTabMessagesFromApi` on the
desync case (frontend thinks running, backend says idle — the
pre-existing recovery path is preserved). When backend says
running, seeds in-flight chunks into the assistant message
matching `snap.currentAssistantId` (creating it if needed).
When backend says non-running, clears `isStreaming` on the
previous in-flight message and nulls `currentAssistantId`.
• `App.svelte:onMount` now awaits `tabStore.hydrateFromBackend()`
before deciding whether to fall back to `createNewTab()`.
Fallback condition is the doubly-defensive
`restored === 0 && tabStore.tabs.length === 0`. `wsClient.connect()`
fires in parallel with hydration — the resulting WS `statuses`
event is per-tab idempotent against the hydrated state, so there
is no race even if it arrives mid-hydration.
What was NOT done (deliberately, deferred to wishlist):
• Pre-existing inconsistency: core `AgentStatus` includes
"waiting_for_key" but frontend `TabStatusSnapshot.status` uses
only the existing 3-state pattern ("idle" | "running" | "error").
Not introduced here; mirrored the existing precedent.
• Restored tabs use defaults for `reasoningEffort`, `agentSlug`,
`agentScope`, `agentModels`, `workingDirectory` — these are not
in the DB `tabs` schema. Future schema expansion.
• Per-delta DB flushing — not needed; the in-memory snapshot
covers the gap between flushAssistant calls.
• LocalStorage cache of tab ids — backend DB is the source of truth.
Process notes:
• Implemented via parallel programmer subagents (flash agents were
requested but unavailable in this environment — substituted with
"programmer" agents, which share the "reads a plan, implements a
single step" charter). Backend (Segment A: getAllStatuses + 5
tests) and frontend (Segment B: types + hydrateFromBackend +
statuses handler + onMount + 8 tests) ran disjoint-file-ownership
in parallel.
• Gemini code review (yolo mode for tool access, explicit
prompt-level write restriction to `report.md` only) returned a
SHIP verdict with no findings against the plan.
• Self-review surfaced one followup gap that Gemini's earlier
plan-mode pass also caught: no explicit test for
`/tabs/:id/messages` failure isolation. Added a test covering
both HTTP-500 and network-error variants alongside a healthy
tab, asserting per-tab failures don't destroy the whole restore.
Tests:
• api/tests/agent-manager.test.ts: +5 (snapshot empty record,
idle-tab field omission, running-tab field inclusion, defensive
copy invariant, omits chunks for running tab with null
currentChunks). 31 total (was 26).
• frontend/tests/chat-store.test.ts: +9 (restore-with-messages,
in-flight seeding, /tabs failure → 0 returned, empty /tabs
array, idempotency when tabs already exist, idle-status when
/status omits, running-snapshot statuses handler seeding,
idle-snapshot statuses handler clearing, per-tab failure
isolation across HTTP-500 and network-error). 44 total (was 35).
Totals: 243 tests across 3 packages all green; typecheck clean on
core + api + frontend; biome clean across 124 files.

switches preserve chat history
Before this change, swapping the model mid-conversation via the sidebar
slider lost all prior turns: the new model saw only the current user
message and treated the conversation as brand-new.
Root cause: `getOrCreateAgentForTab` invalidates the cached Agent
(`tabAgent.agent = null`) whenever the effective keyId, modelId,
permission key, or working directory differs from the cached values.
The replacement Agent was then constructed with `messages: []` and
the post-construction step that loads prior turns from the SQLite
`messages` table simply did not exist. `processMessage` had already
appended the current turn's user message to the DB (line 960) before
calling `getOrCreateAgentForTab` (line 1015), so the DB held the full
context — it was just never read.
Fix: after every `new Agent(...)` in `getOrCreateAgentForTab`, call
`getMessagesForTab(tabId)`, walk backwards to the most recent user-role
row, and assign all strictly-prior rows to `tabAgent.agent.messages`.
The walk-backwards strategy correctly handles two boundary cases:
1. Simple model switch — last DB row is the current user message;
drop it (`Agent.run()` will push it again at line 546).
2. Agent-mode auto-fallback retry — last DB row may be a partial
assistant response flushed by the previous failed attempt; we
drop both that and the current user message in one pass.
System-role rows (config-reload notices, etc.) are preserved verbatim;
`toModelMessages` already strips them before the wire payload, so this
is safe.
The fix covers every Agent-reconstruction trigger, not just the model
slider:
- Sidebar model/key change (the reported case)
- Permission setting change
- Working-directory change (`processMessage` line 951)
- dispatch.toml config-watcher reload (lines 236–237)
- Skills directory watcher reload (lines 249–250)
- `stopTab` after user cancellation (line 775)
If `getMessagesForTab` throws (e.g. DB locked, schema mismatch), we
swallow the error and leave `messages: []` — matching pre-fix
behaviour for that case so this commit never regresses.
Tests (+6 in `packages/api/tests/agent-manager.test.ts`, total 26):
- pre-populates Agent.messages from DB history
- leaves messages empty when DB has only the current turn (first msg)
- excludes a partial assistant trail from a prior fallback attempt
- preserves system-role rows in pre-populated history
- survives a getMessagesForTab failure without crashing
- reloads history on every Agent reconstruction (simulated slider
switch from Opus to DeepSeek across two processMessage calls)
The test rig was extended with:
- `fakeMessagesByTab` map + `setFakeMessages` helper letting tests
inject arbitrary DB rows for the mocked `getMessagesForTab`.
- `constructedAgents` array captured at `run()` entry (not at
construction) so each test sees the post-pre-populate snapshot;
the production code reassigns `agent.messages` after `new Agent()`
returns, so capturing at construction yielded a stale empty array.
- Pluggable `runImpl` hook for tests that want a custom event stream
(not yet exercised; staged for the next round of agent-mode
fallback tests).
Totals: 229 tests across 3 packages all green; typecheck clean on
core + api + frontend; biome clean across 124 files.

SDK compat
- Implement Anthropic prompt caching: first system message + last 2 non-system messages get cache_control: ephemeral, mirroring OpenCode's applyCaching strategy. Move system prompt inline into messages array so providerOptions can attach.
- Add opencode-anthropic provider variant routing MiniMax/Qwen models through the /messages endpoint with x-api-key auth, distinct from the Claude OAuth flow's Bearer auth and Claude Code mimicry.
- Split isAnthropic into isClaudeOAuth (billing header, mcp_ tool prefix, thinking config) and usesAnthropicSDK (cache markers) so non-OAuth Anthropic-format gateways get the right treatment.
- Pin @ai-sdk/anthropic to ^1.2.12: v3 returns LanguageModelV3-spec models that ai v4's streamText rejects at runtime ('AI SDK 4 only supports models that implement specification version v1'). Drop unnecessary V1 casts.
- Restore Opus 4.7 extended thinking by rewriting the outgoing /messages body in the Claude OAuth fetch interceptor: inject thinking: { type: 'adaptive' } (v1 SDK can't emit it), strip temperature/top_p/top_k (Anthropic rejects them with thinking enabled). Gated on max_tokens > 4096 so effort=none still works.
- Bump MAX_STEPS from 10 to 50 to align with AI SDK's stepCountIs(20) default and reduce mid-task halts.
- Fix pre-existing typecheck errors in agent-manager.ts (entry/nextEntry narrowing), app.ts (agentModels body field), KeyUsage.svelte (m guards), and a TS2742 in provider.ts via explicit ModelFactory return type.
- buildFallbackSequence now always returns at least one entry so processMessage runs the agent loop even without keyId/modelId (fixes 4 broken agent-manager tests).
