Additive sandbox provider adapted to this fork's synchronous create_sandbox
factory: agent/integrations/e2b.py registered as a lazy-import entry in
SANDBOX_FACTORIES, so the e2b/langchain-e2b imports only load when
SANDBOX_TYPE=e2b (dark-safe on unset env; unset E2B_API_KEY raises a clean
ValueError only when the provider is selected). Supports reconnect-by-id and
optional E2B_TEMPLATE. Non-langsmith providers skip the GitHub proxy step,
so the GitHub-App token flow is untouched.
Upstream: langchain-ai/open-swe 48217b68 (#1489), re-implemented against the
fork's sync sandbox lifecycle rather than cherry-picked (upstream ships on
the deferred async sandbox.py base).
Docs: provider tables/lists in README, CUSTOMIZATION, INSTALLATION; the
CUSTOMIZATION registration example now shows the lazy-tuple form the code
actually uses. uv.lock refreshed (adds e2b, langchain-e2b, dockerfile-parse).
* chore: bake sfw binary into sandbox image (#1611)
sfw only ships a launcher that fetches its real binary at first run and does a
daily update check against api.github.com/repos/SocketDev/sfw-free. Both fail in
the sandbox (restricted egress; the proxy injects the GitHub App installation
token, which lacks access to that repo), so `sfw yarn install` errors with
"could not fetch its binary". Pin sfw 2.0.6, warm + verify the binary cache at
build, and set SFW_SKIP_UPDATE_CHECK=1 so runs use the baked binary offline.
* feat: editable plan mode + fix review-plan banner overlap (#1610)
* feat: editable plan mode + fix review-plan banner overlap
Lets the thread owner edit the plan markdown by hand from the plan-review
page (Edit -> textarea -> Save) via a new PUT /dashboard/api/plan/{id}
endpoint that re-publishes the plan and mirrors it into the sandbox
plan.md, so approve hands the edited plan to the agent as the source of
truth. Also fixes the collapsed git-panel's floating expand button
covering the "Review plan ->" banner by reserving space for it.

* fix: abort plan approval when the published plan read fails
get_plan_content() swallowed store errors and returned None, so a
transient failure during approve would still mark the plan approved and
dispatch the generic fallback text — silently dropping an owner's edited
plan. Read the plan strictly (raise_on_error=True) so approval aborts
instead, matching the comment read.

* fix: inject reviewer trace context as JSON
Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com>
* fix: address review on PR trace resolution
Use the documented LangSmith metadata filter syntax
(and(eq(metadata_key,...), eq(metadata_value,...))) instead of
has(metadata, '{...}'), which does not match runs — _list_thread_runs
was silently returning nothing. Bound full-text searches to a 90-day
window so they don't hit LangSmith's large-window rate limit.
Also folds in the best-effort branch->head-sha resolver (dropping the
weighted scoring/threshold + repo/file evidence + GitHub hydration),
sandbox JSON injection, and the admin "Resolve trace" dry-run endpoint.
The IDOR findings are moot: resolve_pr_to_threads/summarize_agent_session
were removed; resolution now runs deterministically from the trusted run
config with no model-controlled pr_url or thread_id.
* fix: scope branch trace search to the repo
Branch names like fix-tests aren't unique across repos (or older PRs) in
a shared tracing project, so an unscoped branch hit could resolve to an
unrelated thread and write its runs into the reviewer sandbox. Require
the repo slug to co-occur with the branch in matched runs; the full head
SHA stays unscoped since it is globally unique. Addresses open-swe review
on PR #1612.

* fix: omit plan link in PR description when no plan exists (#1618)
Plan links in PR descriptions were always built from the thread id, so
runs that never produced a plan linked to an empty plan-review page.
Now the plan content store is consulted first; the link is only added
when a plan with non-empty markdown actually exists. A transient store
failure degrades gracefully (no link) rather than blocking PR creation.

- remove PR-babysitting (ci_autofix + ci_monitor graph + webhook wiring)
- dispatch core: agent/dispatch.py with multitask_strategy=interrupt +
durability=sync + completion webhook; reroute all webhook + plan triggers;
drop the racy in-process lock + is_thread_active busy-check

* feat(rebuild): async tools, reconcile, shared http timeouts, assembly tuning
Parallel batch on top of the reliability spine:
- async-ify all 24 tools (drop asyncio.run; requests->httpx); re-implement the
http_request/fetch_url SSRF + DNS-rebinding defense httpx-natively and harden
the IP check to 'not is_global' (+ IPv4-mapped unwrap)
- reconcile.py: stale pending-run sweep (threads.search -> per-thread runs.list
-> cancel_many), wired into the scheduler graph via task='reconcile'
- shared DEFAULT_HTTP_TIMEOUT (agent/utils/http.py) on every bare
httpx.AsyncClient() across utils/dashboard/webapp/middleware
- run budget: MODEL_CALL_RECURSION_LIMIT 5000->250
- fix stale OpenAI->Anthropic fallback id (claude-opus-4-5 -> 4-8)
- drop redundant custom repair middleware (deepagents auto-adds PatchToolCalls)
- confirm tool-result eviction + summarization auto-wired via backend
- slim system prompt ~8% (full harness-profile rewrite deferred)
Co-authored-by: open-swe[bot]
* feat(rebuild): harness-profile prompt + split webhooks out of webapp
- prompt.py: own the system prompt via a registered harness profile
(OPEN_SWE_SHARED_BASE, kept neutral so the read-only reviewer/analyzer that
share it stay safe), registered across all 4 providers; per-thread values
stay in construct_system_prompt. Assembled main-agent prompt ~6.8k -> ~3.1k
tokens (~55% smaller); de-duped PR/commit/suite/force-push guidance; dropped
ALL-CAPS markers.
- webapp.py 3325 -> 1890 LOC: moved 14 per-source handlers into
agent/webhooks/{linear,slack,github}.py; webapp re-exports them for the
routes + tests; moved handlers reach shared helpers via the webapp namespace
to preserve the test suite's monkeypatch targets.
Full suite: 1168 passing, lint clean.

* Restore MODEL_CALL_RECURSION_LIMIT to 5000 for long-running tasks
Reverts the 250 cap from the run-budget change — long-running tasks legitimately

- /webhooks/run-complete: shared-secret auth — dispatch appends ?token= when
RUN_COMPLETE_WEBHOOK_SECRET is set; route verifies via hmac.compare_digest.

- SSRF: extract the URL validator to agent/utils/url_safety.py and apply it
before server-side image fetches in multimodal.fetch_image_block.

* feat: restore forced tool call to prevent premature run stops (#1622)
Restore the ensure_no_empty_msg middleware and the always-call-a-tool system-prompt instruction that #1535 removed. When the model emits a message with no tool call (and hasn't already messaged the user or confirmed completion), the middleware re-injects a no_op / confirming_completion tool call so the run continues instead of ending mid-task.
Shipping to test whether it fixes runs that stop halfway through.

* fix: don't set failure_reply_posted on Slack preprocessing errors
The preprocessing error handler was setting failure_reply_posted=True,
the same idempotency flag handle_run_completion checks to suppress
duplicate run-failure replies. Since preprocessing failures happen
before any run exists but the flag persists on the thread, a subsequent
run failure on the same thread would be silently ignored.
The preprocessing handler already posts its own Slack reply, so the
run-completion idempotency flag should not be set here.

* fix: preserve trace_message_ts when overwriting Slack run mapping
When store_slack_run_mapping is called without trace_message_ts (e.g. on
follow-up Slack mentions), it was unconditionally overwriting the
thread-level mapping and clobbering the timestamp captured from the
initial trace reply. After that, _notify_slack_web_handoff could not find
the original message, so a subsequent move to Web silently skipped the
Slack trace update.
Now, when trace_message_ts is not passed, the existing thread mapping is
read first and its trace_message_ts is preserved.

* fix(ui): pre-bundle shiki/@pierre deps to stop dev dynamic-import failures
shiki lazy-imports a grammar per language and these libs only live inside
lazy route components, so Vite's startup scanner never sees them. They get
discovered on first thread navigation, triggering a dep re-optimize +
force-reload that aborts the in-flight route-chunk import, surfacing as
"Failed to fetch dynamically imported module: .../$threadId.tsx".
Pre-bundle them (and the github themes + common code-block languages) via
optimizeDeps.include so the optimize happens once at startup. Dev-only;
production bundles are unaffected.

* Remove dead breakout-thread e2e scenario after dropping the tool
The merge resolution deferred upstream's Slack breakout-thread tool
(slack_start_new_thread, #1638) since it depends on the #1621 dispatch
module, but the e2e harness still scripted it. Removing the tool name
from fake_llm.py's _tool_step call left a malformed scenario, crashing
the langgraph-dev web server at import (TypeError: _tool_step() missing
'call_id') and failing Playwright E2E.
Drop the "breakout" script scenario, its _is_breakout_request helper +
ScriptRule, and the corresponding full_flow.spec.ts test.
* Revert upstream pnpm switch; keep bun for the UI build
The merge auto-adopted upstream's pnpm switch (#1645) in tests/e2e/
global-setup.ts and ui/package.json, but our fork builds the UI with
bun (vercel.json + the E2E workflow's setup-bun). That left the
Playwright globalSetup running `corepack pnpm install --frozen-lockfile`
with no pnpm-lock.yaml, failing E2E at UI build time.
Revert global-setup.ts and ui/package.json to the dev (bun) baseline,
drop the merge-added ui/pnpm-lock.yaml, and remove the re-added
ui/AGENTS.md (our fork had deleted it).
* Align plan-review e2e + UI with the HEAD (pre-#1635) backend
The merge left a split plan vertical: the backend save_plan/plan_api are
HEAD (we deferred the editable-plan/sandbox-publish features #1610/#1635/
#1637 per #80), but the plan UI and e2e harness were upstream's. The
fake_llm scenario called save_plan(plan_file_path=...) — upstream's
file-based #1635 contract — while HEAD save_plan takes plan_markdown,
so the plan never saved and PlanReview never rendered (E2E failure on
the plan-review locator).
Pass plan_markdown to save_plan, and revert PlanReview.tsx / plan.ts /
$threadId_.plan.tsx / plan_review.spec.ts to the dev baseline so the
whole plan flow (save -> render -> approve -> implement) is consistent
with the HEAD backend.

* feat: repo-scoped dynamic sandbox snapshots
Let admins build a per-repo sandbox image from a custom Dockerfile so runs
targeting that repo boot from a snapshot with its deps pre-baked. Snapshot
selection is purely additive: repos without a `ready` repo-scoped snapshot
always fall back to the configured DEFAULT_SANDBOX_SNAPSHOT_ID.
Backend adds a repo_snapshots store module (Dockerfile + build status keyed by
owner/name), threads the resolved repo through the LangSmith sandbox creation
path, runs builds via SandboxClient.create_snapshot_from_dockerfile in a
throwaway builder sandbox, and exposes admin-only CRUD + build endpoints. The
UI adds an admin-only Agents-tab page (repo picker + Monaco Dockerfile editor +
build status/logs).

* fix: harden repo snapshot builds
Require REPO_SNAPSHOT_BASE_IMAGE for generated Dockerfile templates so admins
cannot accidentally build a repo snapshot from a bare Python image that lacks
Open SWE's sandbox tools. Allow stale building records to be retried by tracking
build_started_at and treating old or missing timestamps as stale.

* fix: document repo snapshot base image config
Document REPO_SNAPSHOT_BASE_IMAGE alongside sandbox snapshot setup and convert
missing base-image configuration into a handled dashboard API error so admins see
a clear configuration message instead of an unhandled template-generation error.

* feat: add user-scoped Currents.dev API key for e2e test investigation
Allow each user to configure their own Currents.dev API key on the
Profile Settings page. The key is encrypted at rest in a per-user
LangGraph Store namespace and feeds server-side read-only tools that
query the Currents REST API (runs, instances, projects, test results)
so agent runs can inspect e2e test failures including screenshots and
DOM snapshots.

* fix: add pagination cursors to currents_list_project_runs
Address review feedback: forward starting_after/ending_before cursor
parameters to /projects/{projectId}/runs so the agent can paginate
beyond the first 50 results.

* feat: server-side Datadog/LangSmith observability tools + team creds
Add team-wide observability credential settings (Datadog DD_SITE/API/APP
keys, LangSmith API key) stored encrypted server-side, with an admin
dashboard section to connect/disconnect each provider. When connected,
get_agent loads read-only observability tools server-side: Datadog via its
hosted MCP server (langchain-mcp-adapters, toolsets=core) and LangSmith
read tools (langsmith_get_trace, langsmith_list_runs). Credentials live in
the LangGraph server process and are never exposed to the sandbox.

* fix: address review on observability tools
Address PR review feedback:
- Authorize observability tools per triggering user (admins + the
OBSERVABILITY_AUTHORIZED_EMAILS allowlist) so prompt-injected runs from
untrusted contributors can't reach team Datadog/LangSmith data.
- Use the documented Datadog MCP auth headers DD_API_KEY / DD_APPLICATION_KEY.
- Store each provider's credentials under its own store key to avoid a
read-modify-write race dropping the other provider on concurrent saves.

* fix: enforce client-side deadline on sandbox execute
The langsmith SDK's default execute path is now a WebSocket stream with
no client-side read deadline. On a live socket where the dataplane never
emits an exit/error frame, CommandHandle.result blocks forever in an
uncancellable thread, wedging the run (introduced by the langsmith
0.8.3 -> 0.8.8 bump in #1385). The command `timeout` is only enforced
server-side, so it doesn't fire.
TimeoutLangSmithSandbox drives a non-blocking CommandHandle and kills the
command if it overruns its timeout by a grace window
(SANDBOX_EXECUTE_CLIENT_GRACE_SECONDS, default 30), returning a timed-out
tool result instead of hanging. WS connect failures fall back to the base
wait=True path, whose HTTP fallback carries its own request deadline.
* fix: fall back to HTTP when WS execute connect fails
run(wait=False) eagerly opens the WebSocket and reads the "started" frame,
so connect/setup failures (and connect timeouts) raise from the run() call
itself, not from handle.result. The previous structure left run() outside
the try, so those failures bypassed the HTTP fallback and would fail every
sandbox command in any environment where the WS path is unavailable.
Move handle creation inside the fallback handler in both execute and
aexecute, and run it via to_thread in the async path since it now blocks on
connect. Add tests for connect-failure and connect-timeout fallback.

create_local_sandbox now mkdir -p's the resolved root dir, so a custom
LOCAL_SANDBOX_ROOT_DIR (or a /tmp path cleared on reboot) no longer fails
sandbox work-dir resolution.
* feat: move github workflows to gh cli
Use LangSmith proxy auth to support gh-driven GitHub workflows while removing custom GitHub wrapper tools.
* docker ignore + snapshot and docker image updates
* updated image and instructions
* removing open_pr if needed after agent call
Previous defaults (4 vCPU / 15 GiB) exceed the maximum sandbox size
the LangSmith API accepts, causing a 400 on every sandbox creation:
sandbox size 4 vCPU / 15360 MiB exceeds the maximum supported size;
must fit within one of: small (1 vCPU / 1792 MiB),
medium (1 vCPU / 3840 MiB), or large (2 vCPU / 7936 MiB)
Default to the "large" cap (2 vCPU / 7936 MiB) so deployments without
DEFAULT_SANDBOX_VCPUS / DEFAULT_SANDBOX_MEM_BYTES env overrides boot
into a working state.

* feat: migrate LangSmith sandbox creation to snapshot API
Replaces the template-based sandbox flow (DEFAULT_SANDBOX_TEMPLATE_NAME /
DEFAULT_SANDBOX_TEMPLATE_IMAGE) with the new snapshot-based flow.
- New required env var DEFAULT_SANDBOX_SNAPSHOT_ID (UUID of a pre-built
LangSmith snapshot; build out-of-band via UI or SandboxClient.create_snapshot)
- Optional DEFAULT_SANDBOX_SNAPSHOT_FS_CAPACITY_BYTES overrides the root FS
size at boot (default 32 GiB)
- Startup-time validation via a FastAPI lifespan hook: the server refuses
to boot with a clear ValueError if SANDBOX_TYPE=langsmith and
DEFAULT_SANDBOX_SNAPSHOT_ID is unset, so failures surface in boot logs
rather than on the first thread
- Reconnect-to-existing-sandbox path unchanged
- Docs (INSTALLATION.md, CUSTOMIZATION.md) updated to describe the new
snapshot workflow
