Adam Moussa	1f060f2a1d	chore: sync upstream/main, defer #1621 modular webhooks (#81) ... * 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. Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> * 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.

Messages render the timestamp inline; tool rows reveal a dim timestamp chip on hover. Real backend created_at still takes precedence when present. * fix: hide client-stamped message timestamps Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> --------- Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> * feat: add PR trace resolution (#1612) * feat: add PR trace resolution Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> * 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.

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.

All client-side over already-fetched sidebar threads; preferences persist in localStorage.

Extract a shared PrHeader component reused by both the git panel and the review main body. Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> * refactor: drop PrHeader wrapper, use shared component directly The review-side PrHeader was just a thin adapter mapping detail -> the shared component's props. Inline it at the call site and use the shared PrHeader directly so there's a single component.

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. Co-authored-by: open-swe[bot] * Restore MODEL_CALL_RECURSION_LIMIT to 5000 for long-running tasks Reverts the 250 cap from the run-budget change — long-running tasks legitimately need many model calls. The notify_step_limit_reached safety net still fires if a run does hit the cap, so runs end with a signal either way. Co-authored-by: open-swe[bot] * fix: address PR review (auth, SSRF, interrupted status, redirect headers) - completion.py: drop `interrupted` from failure statuses — with multitask_strategy=interrupt a follow-up ends the prior run as interrupted, which is healthy, not a failure to report. [open-swe] - /webhooks/run-complete: shared-secret auth — dispatch appends ?token= when RUN_COMPLETE_WEBHOOK_SECRET is set; route verifies via hmac.compare_digest. [corridor-security] - SSRF: extract the URL validator to agent/utils/url_safety.py and apply it before server-side image fetches in multimodal.fetch_image_block. [corridor-security] - http_request: preserve caller headers/extensions across redirect hops instead of dropping them on the first hop. [open-swe] Co-authored-by: open-swe[bot] * chore: remove REBUILD_PLAN.md (planning doc, not needed in the repo) Co-authored-by: open-swe[bot] * fix: fail closed on run-complete webhook auth when secret unset Corridor follow-up: verify_run_complete_token returns False (not True) when RUN_COMPLETE_WEBHOOK_SECRET is unset, so the public route is never unauthenticated. Logs a startup warning when the secret is absent, and dispatch skips registering the webhook when there's no secret (no rejected callbacks). Co-authored-by: open-swe[bot] --------- Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> * 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.

Strip the Socket Firewall guidance from the agent and reviewer prompts so installs run through the project's package manager directly. sfw stays in the Docker image; nothing invokes it now.

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. --------- Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> * chore: avoid recapping Slack replies (#1629) * chore: avoid recapping Slack replies Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> * chore: simplify Slack reply prompt wording Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> --------- Co-authored-by: Ramon Nogueira <270434257+ramon-langchain@users.noreply.github.com> Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> * fix: update Slack trace reply on web handoff (#1630) * fix: update Slack trace reply on web handoff Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> * fix: trigger web handoff on dashboard starts Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> * fix: format web handoff as contextual fragment Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> * 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. * style: ruff format --------- Co-authored-by: Ramon Nogueira <270434257+ramon-langchain@users.noreply.github.com> Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> Co-authored-by: Johannes du Plessis <51395795+johannes117@users.noreply.github.com> Co-authored-by: Johannes du Plessis <johannes@langchain.dev> * fix: pre-bundle shiki/@pierre deps to stop dev dynamic-import failures (#1643) * 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.

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. --------- Signed-off-by: dependabot[bot] <support@github.com> Co-authored-by: Johannes du Plessis <johannes@langchain.dev> Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> Co-authored-by: Ramon Nogueira <ramon.nogueira@langchain.dev> Co-authored-by: Ramon Nogueira <270434257+ramon-langchain@users.noreply.github.com> Co-authored-by: Caroline di Vittorio <43390382+carolinedivittorio@users.noreply.github.com> Co-authored-by: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> Co-authored-by: Johannes du Plessis <51395795+johannes117@users.noreply.github.com> Co-authored-by: Ankush Gola <9536492+agola11@users.noreply.github.com> Co-authored-by: Mukil Loganathan <mukil@langchain.dev>	2026-06-30 16:45:19 -04:00
Johannes du Plessis	911c835c2a	feat: chat with your PR on the review page (#1534) ... * feat: chat with your PR on the review page Add a sandbox-less `chat` graph that answers questions about a single PR from its diff, the published review findings, and read-only GitHub access. - agent/chat.py: deepagents graph, no sandbox (default StateBackend, file mutation + execute tools excluded). PR context is seeded as virtual files under /pr/; a repo-scoped App token is resolved in-graph. - tools: read_repo_file, search_repo_code, list_review_findings. - dashboard/review_chat_api.py + routes: per-user chat thread, LangGraph stream/commands/state/history proxy pinned to the chat assistant, seeds diff/findings/overview on first run. Gated by repo access. - UI: Chat tab wired to a chat-scoped StreamProvider (replaces Coming Soon). * feat: admin setting for review-chat default model Add a 'Open SWE Review Chat' default to team settings (default_chat_model / default_chat_reasoning_effort). get_team_default_model("chat") inherits the Agent default when unset; the chat graph resolves through it. Admin RolePicker gains an 'Agent default' inherit option that clears the override. * feat: multi-conversation review chat (tabs, new chat, history) Replace the single per-PR chat thread with multiple per-user conversations: - threads minted client-side; first message persists with a title derived from the prompt. - list + delete endpoints; chat panel gets a tab strip (history), new-chat (+), close (x), refresh, an intro greeting, and suggested prompts. - get_review_chat now returns availability only (ids are client-minted). * ui fixes * ui: review-chat history dropdown, full-width AI replies, resizable side panel * fix(review-chat): enforce per-user thread ownership on proxy endpoints; reseed PR context on head change --------- Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com>	2026-06-15 17:17:30 -07:00
