Bounds plugin disk use: installing never removed the version it replaced, so
~/.kandev/plugins/<id>/ accumulated a full copy per install forever (4.2GB on
one machine, 3.74GB of it superseded versions). A plugin now keeps its active
version plus one rollback target, pruned only once the new version is
confirmed running.

Per-session events are published on a suffixed bus subject
("shell.output.<sessionId>") but stamped with the bare event-type constant
("shell.output"). The plugin deliverer subscribed with the manifest pattern and
then re-checked that pattern against event.Type, which made every suffixed
subject undeliverable: a 3-segment pattern matched the bus subscription but
failed the re-check on segment count, while a 2-segment pattern passed the
re-check but never subscribed to the 3-segment subject.
Carry the concrete publish subject on bus.Event (stamped in place by Publish in
both the memory and NATS implementations; the NATS receive side prefers the
delivering msg.Subject) and re-check the manifest pattern against it via a new
Event.EffectiveSubject helper that falls back to Type. The concrete subject is
also what plugins receive as pluginsdk.Event.EventType -- already documented in
the proto as "bus subject" -- so a plugin subscribed to "shell.output.*" can
read the session id off it.
Audited all 109 EventBus.Publish call sites: 17 subject families were affected;
office.run.event_appended, the office tree-hold subjects and the cross-plugin
plugin.<id>.<name> already stamped Type with the full subject. Three git.ws
sites in the orchestrator publish on git.ws.<sessionId> while stamping
events.GitEvent, so the subject there is not a suffixed form of its own type at
all -- left as-is, since the gateway routes off the subject and never reads
event.Type. Unsuffixed subjects publish with subject == type, so existing
2-segment subscriptions are unaffected, and the re-check still enforces manifest
segment-count strictness over the bus's looser NATS ">" semantics.
* feat(plugins): implement Host data API write RPCs (CreateTask/UpdateTask/CreateComment)
The api_write manifest capability was a stored no-op. Wire the deferred
phase-2 write RPCs (ADR 0043) so closed-loop plugins (Sentry->task,
Slack slash-command task creation, refactor fan-out) can create and
update tasks and post comments.
- SDK: Host.Tasks() gains Create/Update; new Host.Comments() writer;
CreateTaskInput/UpdateTaskInput/Comment DTOs (pkg/pluginsdk).
- Gating: api_write:tasks gates Create/UpdateTask, api_write:comments
gates CreateComment; undeclared -> gRPC PermissionDenied, per-method
and independent of the read caps on the same resource.
- Writes route through the first-party service layer (task service for
tasks, office service for comments) via backendapp adapters, never a
repository -- so task.*/comment-created events fire and WS updates.
Server stamps source="plugin:<id>"; CreateTask resolves workspace/
workflow defaults and best-effort honors start_agent; UpdateTask uses
a conservative title/description/state/workflow_step_id mask.
- Fixture plugins exercise a CreateTask+CreateComment round-trip;
in-process, real-broker wire, and subprocess tests cover the round-trip
and per-capability denial.
- Docs: spec, GRPC-CONTRACT, HOST-DATA-API.proto, proto comments moved
writes deferred -> implemented; ADR 0043 amended with the concrete
service-layer routing decision.

* feat(plugins): send a message to a task session via Host SendMessage (replaces CreateComment)
The office TaskComment write was the wrong primitive — it's an office/
dashboard construct, not a way to message the agent working a task, and
it only did anything under office reactivity. Replace the CreateComment
write RPC with SendMessage, which delivers a prompt to a task session
through the orchestrator's real delivery path (the same one message_task
uses).
- Proto: swap CreateComment/Comment for SendMessage(SendMessageRequest)
returns SendMessageResponse{session_id, status}; regenerated stubs.
- SDK: Host.Comments() removed; Host.Messages().Send(taskID, sessionID,
text) added (pairs with Messages().List), returning MessageDispatch.
- Gating: api_write:comments dropped; SendMessage gated api_write:messages
(independent of api_read:messages on the same accessor, like Tasks()).
- Delivery: a new pluginsTaskMessengerAdapter (backendapp) resolves the
target session (explicit id verified against the task, or the primary
session), records a user message stamped source="plugin:<id>", then
dispatches by state — running → queue; idle/completed → prompt (resume
if the agent process is gone); never-started → launch; failed dispatch
deletes the recorded message. Wired via SetWriteDeps (live-read).
- Tests: adapter state-machine unit tests (queue/start/prompt/resume/
delete-on-failure/belongs-to-task/no-primary/terminal); SDK, in-process
gating, wire, and subprocess round-trips updated to SendMessage.
- Docs: spec, GRPC-CONTRACT, HOST-DATA-API.proto, proto comments, and the
ADR 0043 amendment updated from comment-create to message-send.

* fix(plugins): address PR review — nil guards, detached contexts, state validation
Follow-up fixes from the #1970 review (Claude + CodeRabbit bots):
- grpcHostServer.CreateTask/UpdateTask/SendMessage: nil-guard the returned
value before toProto() so a custom/test Host returning (nil, nil) yields a
gRPC Internal error, not a server panic (matches GetTask's pattern).
- host.go: fix stale server doc comment (Comments()/CreateComment →
Messages()/SendMessage).
- startTaskBestEffort and the post-resume wait+retry now run on
context.WithoutCancel(ctx): the task/resume is already committed, so a
plugin's incoming deadline must not silently abort the launch/resume.
- pluginsTaskWriterAdapter.UpdateTask validates the state string against the
known task-state enum (excluding orchestrator-owned SCHEDULING) and returns
InvalidArgument, so a plugin typo can't forward a bogus state to the service.
- Tests: add the resume-wait-timeout path (message deleted so a retry can't
duplicate), and a dedicated pluginsTaskWriterAdapter test covering
source→metadata mapping and state validation (both adapters now depend on
narrow interfaces for testability).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(plugins): launch start_agent asynchronously so CreateTask doesn't block
Review nit follow-up: startTaskBestEffort called StartTask synchronously, so
with the detached context the plugin's CreateTask RPC blocked on the
orchestrator's full inline launch path (office lookup, state update, workflow
step move, task fetch) with no bound — and the "asynchronous" comment was wrong.
Move the fire-and-forget into pluginsTaskStarterAdapter (backendapp, no goleak),
mirroring MCP's launchAutoStartTask: the launch runs in a goroutine on a
context.WithTimeout(context.WithoutCancel(ctx), AgentLaunchTimeout), and
StartTask returns immediately. The plugin host stays a simple synchronous call
(its taskStarter contract now documents "returns promptly, launches async").
Adds adapters_plugin_starter_test.go: launch invoked, returns before the launch
completes, detaches from a cancelled caller context, and swallows launch errors.

* docs(plugins): document write validation + SendMessage rollback; harden starter test cleanup
Addresses the final PR #1970 review nits:
- adapters_plugin_starter_test.go: register the block-channel release via
t.Cleanup (sync.Once-guarded) before the goroutine can block, per AGENTS.md.
- GRPC-CONTRACT.md: document CreateTask/UpdateTask validation + error rules
(title required, id required, NotFound on missing task, invalid-state reject).
- spec.md: document that a failed SendMessage dispatch deletes the recorded
message, plus the required-field/NotFound/terminal-session rules.

* feat(plugins): add auth capability for plugin-provided OIDC/SAML login
Plugins can now authenticate a visitor against an external IdP (OIDC/SAML)
and contribute a login button to the pre-auth screen:
- new `auth` manifest capability + a capability-gated X-Kandev-Auth-Login
webhook-response directive; the host mints the kandev_session (ADR 0050),
the plugin never receives the raw token. Plugin-set Set-Cookie is dropped.
- auth.Service.AuthenticateExternal: existing-identity / link-by-email / JIT
member provisioning; refuses to auto-link to an admin; verified-email is
the plugin's contract.
- auth_providers manifest block + plugins.SSOProviders() populate the
anonymous boot payload (auth.ssoProviders); the login page renders a
"Continue with <provider>" button per provider.
- ADR 0050 + plugin-manifest / plugin-authoring / auth spec docs.

* docs: exclude publish_review_findings_kandev from public-docs coverage
The native code-review agent (#1957) added the publish_review_findings_kandev
MCP tool but did not update docs/public/coverage.json; that PR did not touch
docs/public so the path-filtered validator never ran. It's an internal review
reporting tool, not a user-facing feature, so record it as an exclusion.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(plugins,auth): address review on SSO directive and JIT provisioning
- takeAuthLoginDirective strips every case variant of X-Kandev-Auth-Login and
rejects (403) when a plugin sends more than one, so no variant leaks to the
browser and login never uses a nondeterministically-picked assertion.
- provisionExternalUser rolls back the just-created user when the identity
insert fails (transient error or a lost UNIQUE(provider,subject) race) and
resolves to the winning identity, so no account is left without a login and
no email is reserved by an unusable row. Adds userstore.DeleteUser.
- auth spec: mark the login-page SSO buttons + provider discovery as landed.

* feat: add opt-in plugin auto-updater
Automatically update installed plugins in the background, off by default
and opt-in. Builds on the existing verified install pipeline — an
auto-update is just an automatic reinstall of a newer catalog package_url.
Two-tier toggle on Settings > Plugins: an instance-wide default (SQLite
plugin_settings) plus a per-plugin override (tri-state auto_update on the
plugin record, carried forward on upgrade). The AutoUpdatePoller
(~90-min cadence + a boot sweep) upgrades only plugins that are currently
active, opted in, and report update_available; disabled/errored plugins
stay on their installed version.
New endpoints: GET/PUT /api/plugins/settings and
PUT /api/plugins/:id/auto-update.

* fix(plugins): recheck auto-update eligibility at install and fix test mock
Address PR #1903 review feedback:
- Re-check each plugin's current status + effective opt-in immediately before
InstallFromURL (eligibleForAutoUpdate), closing the TOCTOU window between the
candidate snapshot / catalog fetch and the install so a plugin disabled or
opted out mid-sweep is never reinstalled and reactivated.
- Correct the marketplace spec to describe the real failure behavior (shared
with manual updates) instead of promising a version rollback the install
pipeline does not perform.
- Fix the frontend CI failure: the plugins page test mocked the whole
plugins-api module without the new settings/auto-update functions, so
useAutoUpdateSettings threw at mount.
- Add an aria-label to the per-plugin auto-update Switch and Reset control.
- Add a use-auto-update-settings hook test (load, failure, optimistic setDefault,
rollback) and an eligibleForAutoUpdate unit test.

* feat(plugins): add keybindings and modal window capabilities
Add two independent plugin UI capabilities.
Keybindings: plugins declare keybindings in the manifest under
ui.keybindings ({id, default, description}), validated backend-side
(combo grammar + unique ids, requires a UI bundle) and exposed to the
frontend. Plugin JS binds a handler via registry.registerKeybinding(id,
handler); a global dispatcher fires it. Combos are user-overridable in
Settings > Keyboard Shortcuts (namespaced plugin:{pluginId}:{id}) with
conflict detection against core and other plugins.
Modals: host.openModal({title?, content, size?, dismissible?}) returns a
{ close() } handle and renders in a single host-owned Dialog isolated by
PluginErrorBoundary, cleaned up on plugin unload.
Fixture plugin, PLUGIN-API.md / spec, and a Playwright e2e demonstrate a
keybinding handler opening a modal.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(plugins): address review feedback on keybinding dispatch and validation
Core shortcuts now take precedence over plugin keybindings on a colliding
combo (defaultPrevented cooperation between the two capture-phase
dispatchers), a throwing plugin handler no longer aborts dispatch to other
plugins, and the keybinding combo grammar is tightened: the backend validator
and frontend parser both drop the undocumented control/super modifier
aliases and reject shift+digit/symbol combos that can never actually fire
(KeyboardEvent.key reports the shifted character, not the token).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(plugins): stop conflicting core shortcut from double-firing with plugin keybindings
The earlier defaultPrevented guard only covered the central useAppShortcuts
dispatcher. Per-component core shortcuts registered via useKeyboardShortcut
run in the bubble phase, after the capture-phase plugin keybinding dispatcher,
so a plugin-handled-and-prevented combo still triggered the core action too.
Guard useKeyboardShortcut (and use-editor-keybinds, another capture-phase core
listener) on event.defaultPrevented so exactly one action fires per combo.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(plugins): make core shortcuts always win over plugin keybindings
Panel-search, task-switcher, and other core listeners never checked
event.defaultPrevented, so a plugin bound to the same combo (e.g. Cmd/Ctrl+F)
could still fire alongside them. Instead of patching every core listener,
usePluginShortcuts now computes the set of effective core shortcut combos
(registry, resolved through user overrides, plus FIND_IN_PANEL/SAVE) and
skips invoking any plugin handler whose combo is in that set, so the
matching core listener always handles the event exactly once.
Also adds a hook-level regression test for useEditorKeybinds' existing
defaultPrevented guard, and fixes a leaked capture-phase window listener in
use-keyboard-shortcut.test.ts that could bleed into later tests.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(web): keep Cmd+K closing the command panel after shortcut-precedence guard
cmdk's built-in vim bindings intercept Ctrl/Cmd+K and +P as list-navigation
shortcuts and call preventDefault() before the event reaches our window-level
useKeyboardShortcut listeners. Once that hook started bailing on
event.defaultPrevented (added to fix core/plugin shortcut double-firing), the
palette's own Cmd+K close/reopen toggle got silently suppressed whenever focus
was inside the open panel. Disable cmdk's vim bindings on the command palette
so its Ctrl/Cmd+K and +P always reach the app-level toggle.

* docs(plugins): document keybindings and modal window plugin APIs
Fill in the public author-facing docs that the internal plugin-keybindings
and modal-window contract (PLUGIN-API.md, spec.md) already covers: the
registry.registerKeybinding / host.openModal JS surface, the ui.keybindings
manifest field with its combo grammar, and a capability mention on the
Plugins overview page.

* feat(plugins): add capability-gated Host reader for conversation content
Plugins can now read historical user/agent message content over the Host
data API, gated by a new `api_read:messages` capability (ADR 0047). This
unblocks "summarize yesterday"-style plugins that the live `message.added`
bus event alone cannot serve.
- proto: `ListMessages` RPC + `Message`/`MessageFilter` on `service Host`.
- SDK: `Host.Messages() MessageReader`, Go-native `Message`/`MessageFilter`.
- host: `api_read:messages` accessor + denied reader; content sanitized via
`sysprompt.StripSystemContent` (no raw system prompts); RFC3339 `since`/
`until` → `InvalidArgument` on bad input.
- data: new `ListMessagesForPlugin` filtered query (session/task ids, type,
created_at range) through the task service, never the DB file.
- tests: in-process + wire capability gating, content stripping, filter/time
passthrough, pagination, and the SQLite query.
- docs: ADR 0047, spec, plugins-manifest, plugins-authoring.

* feat(plugins): add Host.InvokeUtilityAgent for settings-selectable utility agent
Plugins can now delegate a one-shot LLM step to an operator-configured agent,
gated by a new `agent_invoke` capability (ADR 0048), so a plugin needs no
provider API key of its own.
- setting: new `utility_agent_profile_id` user setting (Settings > System >
Utility Agent), a profile dropdown cloned from the existing utility-agent
path; selectable in the UI.
- capability: boolean `agent_invoke`, enforced like `state`/`secrets`.
- proto/SDK: `InvokeUtilityAgent(prompt) -> text` RPC and
`Host.InvokeUtilityAgent(ctx, prompt)`.
- backend: reuses the sessionless host-utility inference tier (ADR 0002) via a
thin adapter — no agent loop, no task/session/workspace; resolves the
configured profile to (agent type, model). Unconfigured / deleted profile ->
gRPC FailedPrecondition.
- tests: capability gating, completion path (asserts the configured profile is
used and text returned), no-utility-agent and stale-profile error paths,
SDK/wire round-trips, and the settings apply/trim behavior.
- docs: ADR 0048, spec, plugins-manifest, plugins-authoring.

* fix(plugins): resolve utility-agent deps live and bound message filter size
Address CI + review feedback on the host plugin capabilities:
- docs: register the new /settings/system/utility-agent route in
docs/public/coverage.json (fixes the "Validate public docs" CI failure).
- utility agent (ADR 0048): hostUtilityMgr is wired late in boot — after
StartActivePlugins has already spawned boot-active plugins — so snapshotting
the utility deps in hostForPlugin stranded those hosts with nil deps and made
InvokeUtilityAgent return Unimplemented for their lifetime. Read the deps live
from the Service (mutex-guarded) at call time instead; add a regression test
for late wiring reaching an already-spawned host.
- messages (ADR 0047): cap the combined session/task/type filter values at 400
so an oversized filter fails fast with InvalidArgument instead of hitting
SQLite's host-parameter limit at query execution; add a test.

* feat(plugins): show source repo link on installed plugin list and settings
Installed plugins carried no repository URL — a "Repo" link existed only
on marketplace catalog cards, whose repo_url is registry-derived from
plugins.yaml and never reaches an installed record. Let the manifest
declare an optional repo_url so sideloaded and directly-installed plugins
surface the same link.
- manifest: add optional RepoURL (repo_url); validate http(s)-only at
registration so a javascript: scheme can't reach the operator's session.
- Record embeds the manifest, so repo_url flows through JSON to the
frontend PluginRecord with no extra plumbing.
- frontend: extract the shared, guarded PluginRepoLink (+ isHttpUrl) from
the marketplace row and render it on the installed plugin row and the
plugin detail header.
- fixture + docs: exercise repo_url in the e2e fixture manifest and
document the field in the public manifest reference.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(plugins): harden repo_url handling per review
- PluginRepoLink accepts string|undefined|null and isHttpUrl null-checks
before trim, so it can't throw on an absent repo_url (CodeRabbit); drop
the now-redundant truthiness guards at the call sites.
- validateRepoURL trims m.RepoURL in place so the stored/serialised value
matches what was validated (Greptile).

* fix(plugins): serialize empty sync-result arrays instead of null
Sync's result slices (Added/Installed/Missing/Errors) stayed Go nil when
nothing changed, and encoding/json marshals a nil slice as null. The
frontend's SyncResult type declares these as non-nullable arrays and reads
result.added.length unconditionally, so a routine "everything up to date"
sync crashed with "can't access property 'length', e.added is null".
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
* refactor(plugins): initialize sync-result slices at construction
Per review feedback (Claude, Greptile): normalizing nil slices at each
return site in sync() left the invariant fragile — a future early return
would silently reintroduce the null-serialization bug. Initialize
SyncResult's slices non-nil at the struct literal instead, and append the
scan results onto them.
Also tighten the regression test to check exact JSON field values instead
of a raw strings.Contains("null") substring search.
