`instance_port` is only used as a zap log field — it's never written to
the executor metadata map, so carrying it across resume in
`persistentMetadataKeys` was a no-op.
Strip the inline `git checkout -B` block from the Docker and Sprites
default prepare scripts. The kandev-managed postlude
(KandevBranchCheckoutPostlude) is appended unconditionally after every
user prepare script, so keeping the same logic inline made the default
and the postlude two sources of truth that could drift.
Tier 1 of the post-review cleanup. Each item is independently safe; bundling
because they're all small, mechanical, and lint-passing.
- fix(clone): unify injectTokenIntoURL across Docker and Sprites — Sprites
used to ignore GH_TOKEN entirely (a user with only GH_TOKEN set got 401
on Sprites clone but worked on Docker). Promote one
`injectGitHubTokenIntoCloneURL` helper, accept both env vars
(GITHUB_TOKEN wins, matching Docker), and use the documented
`https://x-access-token:T@github.com/` form on both surfaces.
- fix(executor-popover): swap the <span tabIndex role="button"> trigger
for <Button variant="ghost"> so Enter/Space activation, focus rings on
Safari, and disabled semantics come for free.
- test(docker): rewrite TestDockerStopInstance_PreservesSessionDirOnPlainStop
to drive the real DockerExecutor.StopInstance path with ContainerID=""
(skips the docker daemon, exercises the kandev-side cleanup branch).
Previous version only iterated shouldRunExecutorCleanup strings — would
pass even if StopInstance always cleaned up. Now table-driven over
preserve+destructive reasons with on-disk asserts.
- refactor(orchestrator): drop dead `_ = arg` parameters from persist*
helpers (persistResumeState, persistModelSwitchState, persistLaunchState).
Brings signatures from 9→6 args, under the funlen lint cap.
- refactor(orchestrator): collapse byte-identical isContainerizedExecutor
≡ isCloneBasedExecutorType predicate into one.
- refactor(lifecycle): drop dead getMetadataBool, FileUploader.RunCommand,
expandMountSource {home} arm (no production agent ships {home} in
Mounts; codex_acp_test asserts it), dockerTaskBranch one-line wrapper.
The executor section is informational, not a button — readiness state +
sandbox/container/branch fields. Move it to the left top bar (next to
the integrations menu) where it sits alongside the other contextual
info, drop the outline-button styling, and switch from click-to-open to
hover-to-open via HoverCard with 150ms open / 250ms close so the cursor
can travel to the destructive Reset button without flickering.
The trigger is a borderless icon-with-status-dot span; tabIndex keeps
it keyboard-accessible. Reset still works — it opens the existing
confirmation dialog independently of the hover card.
Tests: pointerEnter instead of click for the hover-to-open path.
The READY badge next to the executor name already conveys ready-state;
the dedicated "Environment ready · 12s" row above the executor info
just added vertical noise. Skip rendering for the ready phase (other
phases that surface non-redundant info — preparing, resuming, failed —
still render). Drop top padding on the executor info section now that
nothing sits above it on the happy path.
The previous tighten only fixed the top half — pb under the field rows
plus the Reset-row's full p-2 still left a generous gap below the last
"Sprite ..." line. Same fix applies whether the popover is showing
Docker or Sprites.
EnvironmentInfo: pt-2 pb-1.5 (was py-2) so the bottom field hugs the
divider, and the Reset-row goes from p-2 to px-2 py-1.5 so the button
sits closer to the text above.
The Sprites/Docker info block under the Environment-ready row had too
much vertical breathing room — the header-to-fields gap and the
inter-row spacing piled up and the popover felt airy. Trim the section
to match the snug rhythm of the rest of the popover (px-3 py-2,
1.5-unit gap before the field list, 1-unit gap between rows). Also
unify the Environment-ready row from p-3 to px-3 py-2 so the dividers
between sections sit at the same vertical cadence.
Profiles created in the UI snapshot the *then-current* DefaultPrepareScript
into their stored prepare_script field. Updates to the default — like
shipping the worktree-branch checkout block — never reach those older
profiles, so users keep landing the agent on the chosen base branch
(main) even though the env row carries a feature branch name.
Append a kandev-managed postlude to whatever prepare_script ran (custom
or default), wrapped in a subshell + `|| true` so it's idempotent and
never blocks agentctl from starting. The postlude prefers the remote tip
when origin already has the branch (resume after a destroyed sandbox),
falls back to checking out the existing local branch, and finally
creates one off the current HEAD.
Sprites needed the WorktreeProvider in resolvePrepareScript so the
postlude's `{{worktree.branch}}` actually expands; Docker already had
it.
The Docker e2e gains a regression case that explicitly stores an older
default-style script (clone, no checkout) and asserts the agent still
ends up on the feature branch — locking the contract in regardless of
which default the user happens to have stored.
Every ACP agent's session dir was bind-mounted from ~/.<agent> on the
host into /root/.<agent> in the container. That exposed host state DBs,
session caches, and lock files to the container — codex's rollout DB
caches absolute /Users/... paths, which don't resolve inside Linux and
the agent silently loses prior thread context on resume.
Replace the host bind mount with a kandev-managed per-container session
dir under <kandev-home>/agent-sessions/<instance_id>/. Before the
container starts, selectively copy the auth-relevant files (the same
files Sprites already copies via RemoteAuth.SourceFiles) into that
dir; everything else — state DBs, sessions/, lock files — stays on the
host and the agent rebuilds them inside the container with
container-local Linux paths.
The change is agent-agnostic: any agent that has SessionDirTemplate
+ SessionDirTarget gets the new behavior automatically. Cleanup runs
on destructive stops only (task/session deleted/archived), mirroring
the Sprites preserve-on-stop rule so plain stops let resume re-attach
to the same agent state.
Codex was the only agent that bind-mounted its host home into the
container via an explicit `Mounts: [{home}/.codex → /root/.codex]`
entry, while every other ACP agent uses `SessionConfig.SessionDirTemplate`
+ `SessionDirTarget`. Move codex onto the same surface so the
host-state isolation work in the next commit covers it uniformly.
This change alone does not stop the host-state leak — the bind mount
still resolves to the host's ~/.codex for now — but it removes the
last agent-specific branch in the runtime config so the docker
container manager can apply one rule for all agents.
The bottom Resume button on the chat panel was leaving users staring at
nothing for the 5-30s reconnect window: prepare-progress events are
intentionally suppressed on resume (the workspace is already there), so
the popover sat in the idle phase even while session.state was STARTING.
Synthesize a "resuming" phase from session state when no prepare events
are flowing, rendered as a spinner row in the popover with copy
"Resuming session — Reconnecting to the existing environment…". The
button icon also flips to the spinner so the toolbar advertises the
in-flight work without the user having to open the popover.
Extract the prepare-status reducer + section component into their own
file so the main popover module stays under the 600-line ESLint cap.
Adds a Docker e2e test that exercises the user-visible stop-then-resume
flow: launch session, stop it via WS session.stop, launch a fresh
session on the same task, and assert the same task environment +
container ID are reused and the kandev feature branch is preserved.
Also nudge the executor popover padding: when the prepare-status
section is rendered above the Sprites/Docker info block, the cumulative
top+bottom paddings looked too generous around "Sprites sandbox" /
"Local Docker". Tighten both sections vertically without affecting the
horizontal rhythm or the bottom action row.
StopInstance was calling sprite.Destroy() unconditionally, so every
session stop tore down the cloud sandbox. Resume then always fell into
the missing-sandbox fallback, re-cloned the repo, re-ran the prepare
script, and lost the agent's working tree. That's a 30s+ round-trip
for what should be "stop the process, then re-attach later".
Limit Destroy to terminal lifecycle reasons (task/session
deleted/archived), the same set runTerminalCleanupScript already uses.
Plain stops just close the proxy and leave the sandbox alive.
Also update the existing Docker e2e regex: the feature-branch suffix is
now a deterministic 6-hex-char prefix of the task UUID rather than a
random 3-char tail, so resume on legacy env rows lands on the same
branch.
Now that BaseBranch is preserved on resume for clone-based executors,
the missing-sandbox fallback warning detail names the actual branch
("Cloning … on the same branch main") instead of the "(unknown)"
placeholder. Add a regression test so a future change to the resume
metadata propagation can't silently regress that copy.
When a sandbox is destroyed and we provision a fresh one for the same
task, the agent may have previously committed and pushed onto the
feature branch. The previous prepare scripts only ran `git checkout -b
{{worktree.branch}}` which would overwrite that progress with a fresh
branch off the chosen base.
Try `git fetch origin <feature>` first; on success, `git checkout -B`
against the remote tip so the agent picks up where it left off. Falls
back to a fresh local branch when origin has nothing.
Also add the same checkout block to the Sprites prepare script — it was
missing entirely, so every Sprites session was committing onto main.
Sprites tasks committed straight onto the chosen base branch because
SpritesPreparer didn't populate WorktreeBranch and the orchestrator's
"forward env.WorktreeBranch on reuse" check only fired for Docker.
Mirror the Docker preparer's TaskBranchName generation in Sprites,
extract a shared `nonWorktreeTaskBranch` helper that uses a
deterministic suffix derived from the task ID (so legacy env rows that
predate this change resolve to the same branch on every resume), and
let the orchestrator forward env.WorktreeBranch for any clone-based
executor — Docker or Sprites.
Sprites and Docker resumes were sending the launch request with an empty
BaseBranch, so the in-sandbox prepare script's `git clone --branch <X>`
shifted positional args and failed with "repository '/workspace' does
not exist". applyResumeRepoConfig only set BaseBranch inside the
worktree-specific block; widen that to all executors that require a
clone URL.
Local executors are intentionally left untouched: LocalPreparer reads
BaseBranch and forces a `git fetch && git checkout` against the user's
own workspace, which would clobber the "use current state" path.
IconContainer's vertical ribbing reads as a microchip on small sizes.
IconBox is an unambiguous outlined cube. Use it for both docker
variants so the executor surfaces look like a box, not a chip.
The desktop task top bar carried a small cloud icon (RemoteCloudTooltip)
in the breadcrumb cluster while the right-side Executor popover showed
the same kind of info — two surfaces for one concept. Remove the cloud
icon from the desktop top bar; kanban cards, task list rows, and the
mobile top bar keep theirs since they have no popover.
The popover button now picks its icon by executor type (cloud for
sprites, container for docker, server for local PC) using a shared
getExecutorStatusIcon helper. While the prepare progress is preparing
the icon swaps to a spinner so the user can see at a glance that work
is in flight.
The popover content gains a Preparing-environment section that streams
"Step N of M: <step>", an amber inline note when the missing-sandbox
fallback is in progress, an Environment-ready row with duration on
success, and a failed-step summary on failure. Polling promotes to the
active 3s cadence while preparing so the icon flips to ready without
the user opening the popover.
When the only warning on a completed prepare is the missing-sandbox
fallback notice, render "Environment prepared on a fresh sandbox" in
the header instead of the generic "Environment prepared with warnings".
The fallback row still carries its own amber warning callout so the
user understands why a fresh sandbox was provisioned.
Resuming a Sprites task whose sandbox was destroyed upstream returned
"sprite not found" and dead-ended the user. Detect the upstream 404 via
a typed ErrSpriteNotFound sentinel, mark the reconnect step skipped with
a user-facing warning explaining what happened, swap the prepare plan
in place to the fresh-provision shape, and continue the launch under a
new sandbox name on the same branch.
The progress plan is now mutable so the reporter can stream the fresh
steps live after the reconnect-then-fresh transition. Only the explicit
not-found case triggers fallback; other reconnect failures still
surface as before, and the fallback fires at most once per launch.
Local docker tasks were rendering the Docker brand "chip" mark while
remote docker uses the container glyph. Map both variants to
IconContainer so the executor surfaces look consistent.
Backend:
- service_task_environments: fail closed when checkAnySessionRunning
errors so a transient DB hiccup can't bypass the running-session
guard and tear down a live container/sandbox; teardown is now truly
best-effort with errors.Join across container/sandbox/worktree, so a
failed Docker call doesn't permanently orphan the worktree on retry.
Adds tests for the running-check error path and the multi-resource
best-effort path.
- executor_execute: propagate GetTaskEnvironmentByTaskID errors instead
of silently launching a fresh environment that orphans existing
containers/worktrees; gate environment reuse on matching ExecutorType
so a profile switch doesn't pass stale PreviousExecutionID/container
IDs to the wrong backend.
- task_environment_handlers: reject malformed JSON on POST
/tasks/:id/environment/reset (still allow empty body) so a destructive
endpoint doesn't silently proceed with a bad payload.
- worktree (PushEnvironmentBranch): bound git push with a 30s context
timeout and disable interactive prompts via GIT_TERMINAL_PROMPT=0
so a stalled remote can't hang the request thread.
- manager_environment: explicitly call ensureClient() before
ContainerMgr() in DestroyContainer/GetContainerLiveStatus so a missing
Docker daemon surfaces as "docker unavailable" rather than the
generic "container manager not initialized".
- container: WorkingDir always uses the in-container /workspace path
rather than the host workspace path (Docker would happily start in an
unrelated directory in host bind-mount mode); bootstrap now logs the
prepare-script exit code so failures show up in container logs.
- docker/client: CreateContainerInteractive honors ContainerConfig.Entrypoint
so the same config struct produces consistent behavior on both creation
paths.
Frontend:
- executor-settings-button: extract useTaskEnvironment hook (component
shrinks below the 100-line limit); only treat 404 as empty env (other
errors no longer wipe a valid environment); track "loaded once" via a
ref so loadEnv doesn't depend on env state — that dep was creating a
new function identity on every successful poll, cancelling the
3-second interval and turning the popover into a tight loop hammering
/environment/live; copy-shell command uses sh instead of bash so it
works on user-built minimal images.
- task-reset-env-confirm-dialog: AlertDialogAction onClick calls
e.preventDefault() so Radix's auto-close doesn't dismiss the dialog
before the async reset completes (loading spinner now visible; close
is parent-controlled via onOpenChange).
- remote-credentials-card: track env method in selectedIds the same way
files/gh_cli_token are tracked, and let initialChoice match either
selectedIds OR envSecretId. First-time env-credential setup for an
agent that exposes both files+env was broken: clicking the env radio
never updated state, choice re-derived to "none", and the secret
picker disappeared before the user could pick anything.
- e2e/executor-reuse: select the acknowledge checkbox by label, not by
positional last(), so adding another checkbox to the dialog can't
silently target the wrong control.
Format pass on prettier-flagged files; gofmt fixed two whitespace
nits in lifecycle files.
Remote executors (local Docker, remote Docker, Sprites) bind-mount the
linux/amd64 agentctl binary into the container. On non-Linux hosts (e.g.
macOS dev installs) running plain \`make build\` produced only the host
binary, so the first Docker session would fail with:
failed to build container config: agentctl linux binary not found
The top-level \`make dev\` already special-cased non-Linux hosts to chain
\`build-agentctl-linux\`, but \`make build\` and \`make start\` skipped it.
Add it as a dependency of the standard backend build so every install
ships a usable linux variant. Cross-compiling agentctl is fast (~1-2s)
and the binary is ~20 MB, so the cost is negligible.
Users who hit the error can run \`make build-backend\` (or \`make build\`
in apps/backend) to regenerate; setting KANDEV_AGENTCTL_LINUX_BINARY
remains a manual override.
A new Playwright project — \`docker\` — runs container-bound E2E specs
against a backend with KANDEV_E2E_DOCKER=1. The fixture probes for a
Docker daemon and skips the worker entirely when none is reachable, so
contributors without Docker can still run the rest of the suite.
The fixture builds a tiny kandev-agent:e2e image once per machine
(node:22-slim + git/curl), pre-seeds a local_docker executor profile,
and seeds a local repo with a file:// origin so the executor's
clone-inside-container path resolves without network access. A small
WS-based session.launch helper is added to the api-client for tests
that need to launch additional sessions on an existing task.
First spec — docker-launch.spec.ts — covers the smoke path: a session
launches in a real container, the task environment records its
container_id, and \`docker inspect\` confirms the container exists.
Two follow-up specs (multi-session env reuse + recovery from external
container removal) are wired up but marked test.fixme with comments
pinpointing the backend gaps that block them: persistTaskEnvironment
isn't called for workflow-prepared sessions (so task_environment_id
stays empty on those rows), and DockerExecutor.reconnectToContainer
loses the agentctl handshake auth token across launches (so reconnect
401s and falls back to a fresh container every time).
Run locally with: \`pnpm --filter @kandev/web exec playwright test
--config e2e/playwright.config.ts --project=docker\`.
Lay the backend groundwork so the existing mock-agent can run inside
local_docker containers — needed for real-Docker E2E tests that don't
require Anthropic/OpenAI API keys.
Container builder bind-mounts a host mock-agent binary at
/usr/local/bin/mock-agent when KANDEV_MOCK_AGENT_LINUX_BINARY is set
(or build/mock-agent-linux-amd64 sits next to the kandev binary), the
same pattern already used for agentctl. MockAgent.BuildCommand always
resolves via PATH so the same command works on host (E2E PATH includes
bin/) and in containers (mounted at /usr/local/bin/mock-agent).
Mock now declares non-nil empty RemoteAuth so it counts as a
remote-capable agent. The remoteauth catalog includes specs even with
zero methods, and the frontend gating helper treats an empty-method
spec as "no credentials needed" — letting mock-agent pass the
configure-on-executor check that hides uncatalogued agents on remote
executors.
repositoryCloneURL falls back to the local origin remote URL when the
repo has no provider info, so local-only repos with a real remote
(including file:// remotes used in E2E) work on remote executors that
clone inside the container.
Makefile: build-mock-agent-linux target mirrors build-agentctl-linux.
Filter the agent profile dropdown in both the Create Task dialog and the
New Session dialog to only show agents that are actually configured for
the selected executor profile.
For local/worktree executors, no gating (agents need no extra creds).
For Docker/Sprites profiles, an agent is "configured" iff one of its
remote-auth methods has a value in `remote_credentials` or a non-null
secret in `remote_auth_secrets`. Agents without an entry in the remote
auth catalog (Copilot, Amp, OpenCode, TUI, mock) cannot carry creds on
remote executors and are blocked.
Spec IDs match `AgentProfileOption.agent_name` (the registry-type string
like "claude-acp"); `agent_id` is a DB UUID and unrelated to the catalog.
The Create Task footer surfaces a "No agent profile is configured for X"
tooltip and disables submit when the selected executor profile has no
compatible agents. The New Session dialog auto-swaps to the first
compatible agent and shows the same banner inline.
`useRemoteAuthSpecs` returns a `loaded` flag so callers don't filter
during the initial fetch (would otherwise hide everything).
Three independent fixes that all surface together while iterating on the
Docker executor flow:
- Remote Credentials card: the per-agent "Configured" / "Not Configured"
badge was driven by useState that only seeded once on mount. Picking a
secret in the dropdown updated the parent's `agentEnvVars` map but the
local `choice` never moved to `"env"`, so the badge stayed grey until
the page was reloaded. Derive `choice` straight from props every render
so the badge tracks live state.
- ACP session/load: when the agent process restarted between turns
(common with claude-agent-acp because its session map is in-memory),
the host's session/load call failed with JSON-RPC -32002 "Resource not
found" and the entire launch errored out. Treat that as the same kind
of "session is gone" signal as -32601 / capability=false and fall back
to session/new. Worst case the agent loses prior context; best case
the user just keeps typing.
- Executor Settings popover: dropped Execution ID and Environment ID
rows (debug-only noise users don't need), kept Container ID + the
copyable `docker exec -it … bash` line, added a live status badge
with tones for running / exited / paused / dead / error / missing,
and a 3-second polling interval so the badge follows the real
container state. New `GET /api/v1/tasks/:id/environment/live`
endpoint plumbs Docker `inspect` data through the lifecycle manager
→ task service → handler. ContainerLiveStatus mirror type at the
service layer keeps lifecycle types out of the public surface.
The Remote Credentials card (per-agent secret picker, plus the GitHub
credential checkbox) is rendered for any remote executor — Sprites,
local_docker, or remote_docker — but the save path in both the create
and edit pages only emitted `remote_auth_secrets` and `remote_credentials`
when `isSprites` was true. Selecting a secret for the Claude / Codex /
Auggie ANTHROPIC_API_KEY-style entry on a Docker profile updated form
state, the dropdown showed it as picked, but Save Changes silently
dropped the value before posting to the API. On reload the agent showed
as "Not configured", and any session start failed with
`{"code":-32000,"message":"Authentication required"}`.
Switch the guards to `isRemote` so the same data persists for all remote
profile types. The backend orchestrator already propagates
`profile.config.remote_auth_secrets` and `remote_credentials` through to
metadata for any containerized executor and resolves them via
`applyContainerCredentials` → `resolveAuthSecrets`, so no backend change
is needed once the values actually land in the saved profile.
Two follow-ups to the Docker bootstrap work:
- The 30 retries × 500ms = 15s budget for agentctl health was too tight.
In the previous flow agentctl was a separate exec from the prepare
script, so it came up immediately. Now it runs after the prepare
script (which does git clone, optional installs), so first launch can
easily exceed 15s and produce a misleading "agentctl not healthy after
30 retries" error. Bumped to 240 retries (120s) and surfaced the last
underlying error in the message so failures point to the real cause.
- Prepare scripts commonly start with `set -e`/`set -eu`; running them
via `eval` propagated the option to the outer bootstrap shell, so any
failure killed the bootstrap before `exec /usr/local/bin/agentctl`.
Run prepare in a subshell so its `set -e` is contained, and start
agentctl regardless. If prepare fails, agentctl still comes up — the
host can connect, surface the failure, and let the user debug from
the Executor Settings popover.
Make the Docker executor work with a Dockerfile users can actually build,
without depending on a maintainer-shipped image:
- The container now launches a small bootstrap (`sh -c "$KANDEV_PREPARE_SCRIPT
; exec /usr/local/bin/agentctl"`) regardless of the image's ENTRYPOINT.
The agent CLI is no longer wired through container Cmd; agentctl receives
it later via its CreateInstance HTTP API.
- Host agentctl-linux binary is mounted into the container at
/usr/local/bin/agentctl via the existing AgentctlResolver. User-built
images don't have to bake it in.
- Default Dockerfile in the executor profile UI replaced with a working
node:22-slim + git + curl image — runs npx-based ACP agents (Claude,
Codex, OpenCode, Auggie) out of the box.
- lifecycleAdapter now exposes RequiresCloneURL / ShouldApplyPreferredShell
so the orchestrator can correctly identify containerized executors and
resolve the clone URL. Without this, applyRepositoryConfig short-circuits
on `e.capabilities == nil`, the cloneURL is never resolved, and the
prepare script fails with `repository '{{repository.clone_url}}' does
not exist`.
- applyRepositoryConfig also surfaces the resolved clone URL to script
metadata so the prepare script can interpolate {{repository.clone_url}}.
- docker.ContainerConfig gains an Entrypoint field, plumbed to the docker
client.
Verified end-to-end on a local stack with the new minimal image: the
container starts, bootstrap clones the GitHub repo, agentctl launches and
hands off to claude-acp inside the container.
Adds two regression tests for the recent Docker fixes:
- container_config_test.go (Go unit): asserts buildContainerConfig
expands `{workspace}` in WorkingDir (defaulting to /workspace when no
host WorkspacePath is set) and that ContainerConfig.ImageTagOverride
takes precedence over the agent runtime's hardcoded `rt.Image`. No
Docker daemon required.
- docker-profile-persistence.spec.ts (Playwright E2E): creates a
local_docker executor + profile, opens the profile edit page, clicks
"Use defaults" to populate the Image Tag input + Dockerfile editor,
hits Save, then refetches the profile via API and reloads the page to
verify both fields round-trip through `profile.config`. Catches the
prior regression where DockerSections owned the form state locally
and never wrote it back. Runs against the existing E2E backend that
has KANDEV_DOCKER_ENABLED=false — we only test the persistence path,
not container creation.
Adds an api-client helper (`getExecutorProfile`) for the round-trip
assertion.
Two bugs:
1. The Dockerfile editor and Image Tag input on the executor profile page
stored their values in component-local useState inside DockerSections,
not in the form state. Saving the profile never wrote them back, so
"Use defaults" / typing in the editor / changing the tag never
persisted — and the Build button was the only thing that consumed
them. The same gap existed in the new-executor flow's
buildProfileConfig.
Lift `dockerfile` and `image_tag` into useProfileFormState (edit) and
useCreateProfileFormState (new), and emit them in buildSaveConfig /
buildProfileConfig so they round-trip through profile.config.
2. Even when an image_tag is set on the profile, the container builder
ignored it. imageName was always derived from the agent runtime's
hardcoded `kandev/multi-agent`, so a user who built a custom image
like `kandev/agent:latest` would still see Docker fail with
"No such image: kandev/multi-agent:latest".
Propagate `profile.config.image_tag` → metadata
(`image_tag_override`) → ExecutorCreateRequest → ContainerConfig,
and let it override `rt.Image` in buildContainerConfig when set.
Also align the frontend default image tag (kandev/multi-agent:latest)
with the backend's hardcoded runtime default so users who don't override
end up with a working build.
The agent runtime config carries `WorkingDir: "{workspace}"` for most ACP
agents. Mount sources were already expanded via expandMountSource, but
WorkingDir was passed through verbatim, so Docker rejected new containers
with:
Error response from daemon: the working directory '{workspace}' is
invalid, it needs to be an absolute path
Run the same expansion on WorkingDir, defaulting to /workspace when no
host WorkspacePath is set (the clone-inside-container case introduced by
PR #654).
A new button on the task top bar opens a popover showing the active
TaskEnvironment — executor type, status, container/sprite/worktree
identifiers, and a copy-ready 'docker exec' command for local Docker.
The popover hosts the destructive Reset Environment action so users have
one obvious place to inspect and manage the environment without
cluttering the New Session dialog.
The reset confirmation dialog requires explicit acknowledgement that
uncommitted changes will be lost. When the environment has a host-side
worktree it offers an opt-in 'push branch before resetting' checkbox so
committed work can be pushed first; the backend aborts the reset on
push failure.
- task-environment-api.ts: fetchTaskEnvironment + resetTaskEnvironment
- executor-settings-button.tsx: popover trigger + identity panel
- task-reset-env-confirm-dialog.tsx: destructive confirm with push opt-in
- task-top-bar.tsx: wire the new button into the right-side controls
- e2e: replace fresh-env-toggle test with reset-from-popover flow
Users sometimes need a clean slate — broken packages, stale caches, a
container that drifted into a bad state. Reset Environment is the explicit
escape hatch: tear down the recorded container, sandbox, and/or worktree
for a task and delete the TaskEnvironment row so the next session starts
fresh.
- service.ResetTaskEnvironment(taskID, ResetOptions) is the entry point.
ResetOptions.PushBranch optionally git-pushes the workspace branch
before teardown so committed work isn't dropped on the floor; a failed
push aborts the reset and leaves the environment intact.
- A new EnvironmentDestroyer interface in the task service hides the
per-resource teardown behind a single seam, implemented in cmd/kandev
by delegating to lifecycle.Manager (containers, sprites) and
worktree.Manager (worktrees, branch preserved).
- lifecycle.Manager.DestroyContainer / DestroySandbox dispatch to the
Docker and Sprites executor backends without leaking model types into
the lifecycle package.
- Reset is blocked while any session on the task still has an
ExecutorRunning row (returns ErrSessionRunning → HTTP 409). Per-resource
teardown is best-effort but the DB row is only removed once everything
is confirmed gone or already missing, so a partial failure is retryable
by clicking Reset again.
- Endpoint: POST /api/v1/tasks/:id/environment/reset.
Worktree, container, and sandbox IDs now flow uniformly from a persisted
TaskEnvironment back into LaunchAgentRequest through a single helper. This
gives Sprites session-to-session reuse the same first-class treatment that
Docker already gained from the GitHub-token-injection PR, and lets a fallback
launch refresh the environment row instead of leaving stale IDs in the DB.
- applyExistingEnvironment propagates WorktreeID, ContainerID (via metadata),
and SandboxID (as sprite_name metadata) onto the launch request
- persistTaskEnvironment refreshes those IDs when the executor ends up
creating new resources (e.g. the previous container was pruned)
- extractSandboxID lifts the sprite identifier out of executor response
metadata so it can be persisted on the TaskEnvironment row
