feat(runtime): implement goal continuations (#3858)
* implement goal continuations * fix(goal): address review findings for goal continuations - goal: key the no-progress breaker on a signature of the latest visible assistant evidence instead of the evaluator's volatile free-text, so it actually fires on stalled turns; thread the signature through every worker persist / no-progress call site - goal: align _stand_down_reason default caps with should_continue_goal (8 / 2) so the two gate functions agree on goals missing the fields - runtime: offload the synchronous checkpointer fallback via asyncio.to_thread (goal.py + worker.py) to keep blocking IO off the loop - frontend: i18n the GoalStatus "Goal" label (goalLabel in en/zh/types) - frontend: extract pure composer helpers into input-box-helpers.ts with unit tests (parseGoalCommand, readGoalResponseError, skill suggestions) - tests: cover the evidence-based no-progress and default-cap behavior - docs: align backend/AGENTS.md goal paragraph with actual behavior - e2e: prettier-format chat.spec.ts (fixes the lint-frontend CI failure) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * feat(frontend): hide goal continuation counter until the agent continues The goal status bar rendered a raw "0/8" before any auto-continuation, which read as a mysterious score. Now the counter is hidden until continuation_count > 0, then shows "Continuing N/M" with a tooltip explaining the auto-continuation cap. - Extract getGoalContinuationDisplay into a pure helper (hides at 0) + unit tests - Add goalContinuing / goalContinuationTooltip i18n keys (en/zh/types) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(goal): address review findings for goal continuations Frontend correctness - Fix the optimistic /goal result permanently shadowing server goal state: the streamed continuation counter never surfaced for a goal set in-session. Extract a shared useActiveGoal hook (used by both chat pages) that reconciles the optimistic copy with server state via a goalReconciliationKey, de-duping the copy-pasted goal block across the two pages. - Stop /goal status|clear failures from escaping handleSubmit as unhandled rejections (handleGoalCommand now returns success; the run only starts when a goal was actually saved). - Use a function replacer for the goal-status toast so an objective containing $&/$1 isn't treated as a replacement pattern. Backend cleanliness / correctness - De-duplicate four byte-identical helpers (_call_checkpointer_method, _message_type, _additional_kwargs, _is_visible_message) by importing them from runtime.goal instead of re-defining them in the run worker. - Remove the dead `checkpoint_tuple.tasks` durability guard (CheckpointTuple has no tasks field) and document that pending_writes is the durability signal. - Decompose the 176-line _prepare_goal_continuation_input: extract _reread_goal_and_checkpoint and a _persist closure so the thread-unchanged guard and stand-down persistence aren't open-coded three times. Document the last-writer-wins write-window limitation as a follow-up. - Add a shared parse_goal_command helper and use it from the TUI and IM-channel /goal handlers (one place for the status/clear/set semantics). Tests - Restore the 11 command-registry tests dropped by the previous goal change (filter_commands ranking/description, build_registry builtins/skills, resolve cases) alongside the new goal tests. - Add coverage for the IM-channel _handle_goal_command, the TUI _handle_goal handler, parse_goal_command, and goalReconciliationKey. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix goal review feedback * fix goal continuation checkpoint races * prioritize goal commands while streaming Route composer submits through a shared helper so /goal commands can be handled before the streaming stop shortcut, while ordinary streaming submits still stop the active run. Testing: cd frontend && pnpm exec rstest run tests/unit/components/workspace/input-box-helpers.test.ts tests/unit/components/workspace/goal-status-helpers.test.ts; cd frontend && pnpm check * preserve goal status during clarification Keep omitted stream goal fields distinct from explicit null clears so clarification interrupts do not hide an active thread goal that is still present in the checkpoint. Testing: pnpm exec rstest run tests/unit/components/workspace/use-active-goal.test.ts tests/unit/components/workspace/input-box-helpers.test.ts tests/unit/components/workspace/goal-status-helpers.test.ts; pnpm check; git diff --check * style: format active goal hook Run Prettier on use-active-goal.ts to satisfy the frontend lint workflow formatting gate. Testing: pnpm format; pnpm exec rstest run tests/unit/components/workspace/use-active-goal.test.ts tests/unit/components/workspace/input-box-helpers.test.ts tests/unit/components/workspace/goal-status-helpers.test.ts; pnpm check; git diff --check * fix goal review followups --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> |

feat(subagents): system-maintained delegation ledger to stop redundant re-delegation (#3877)
* feat(subagents): add delegations ledger field + reducer to ThreadState * feat(subagents): pure helpers to derive + format the delegation ledger * feat(subagents): DelegationLedgerMiddleware records + injects the ledger * feat(subagents): register DelegationLedgerMiddleware for lead when subagents enabled + docs * add runtime log * chore(subagents): make delegation-ledger injection log production-ready * test(subagents): make delegation-ledger registration tests config-free; refresh ultra replay golden for delegations channel * refactor(subagents): derive TERMINAL_STATUSES from SUBAGENT_STATUS_VALUES + pin it Make thread_state's TERMINAL_STATUSES a frozenset over the status contract's SUBAGENT_STATUS_VALUES instead of a hardcoded literal, so the terminal-status set can never drift from the contract. Add a pinning test asserting the derivation and that the non-terminal "in_progress" stays excluded. Addresses PR #3877 review. --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(tool-search): reliably hide deferred MCP schemas by removing the ContextVar (closures + graph state) (#3342)
* feat(tool-search): add hash-scoped promoted state to ThreadState * feat(tool-search): add immutable DeferredToolCatalog with stable hash * feat(tool-search): add build_deferred_tool_setup + Command-writing tool_search * refactor(tool-search): replace deferred-tool ContextVar with closures + graph state (#3272) Build the deferred catalog + tool_search tool per agent from the policy-filtered tool list (after skill allowed-tools), pass deferred_names + catalog_hash explicitly to DeferredToolFilterMiddleware and the prompt, and record promotions in ThreadState.promoted (scoped by catalog_hash) via a Command-returning tool_search. Removes DeferredToolRegistry and the _registry_var ContextVar so deferral no longer depends on build/execute sharing an async context. MCP tools are tagged with metadata[deerflow_mcp]; client.py assembles deferral the same way. Catalog is built AFTER tool-policy filtering (no policy-excluded tool can leak via tool_search) and assembly is fail-closed. Migrate tests off the deleted registry APIs; delete the obsolete ContextVar-based #2884 regression (re-covered by state-based tests in a follow-up). * test(tool-search): lock tool_search promotion into next model turn via graph state * test(tool-search): cross-context, policy-leak, fail-closed, #2884 isolation regressions * test(tool-search): align real-LLM e2e with closure-based deferred setup * docs: update DeferredToolFilterMiddleware description for closure+state design * style(tests): drop unused import in test_deferred_setup (ruff) * test(tool-search): harden merge_promoted + replace tautological catalog test From independent code review: - merge_promoted: use existing.get("catalog_hash") so a forward-incompatible or externally-injected persisted promoted dict triggers a replace instead of a KeyError crash; add regression test for the malformed-existing case. - test_deferred_catalog: replace the `== [] or True` tautology (a test that could never fail) with a deterministic invalid-regex->literal-fallback check (positive match on calc + negative empty match). - DeferredToolCatalog: comment why frozen-without-slots is required for the cached_property hash/names fields (adding slots=True would break them). * fix(tool-search): read tool_search.enabled from self._app_config in client DeerFlowClient._ensure_agent called get_app_config() directly to read tool_search.enabled, but the client already resolves and stores its config as self._app_config at construction (and uses it everywhere else). The bare call re-resolves config from disk at agent-build time, which raises FileNotFoundError in environments without a config.yaml (CI) — test_client.py's fixture only patches get_app_config during __init__, so the later call hit the real loader. Use self._app_config, matching the rest of the client. * test(tool-search): lock tool_search post-policy append ordering tool_search is appended after skill-allowlist filtering, so the allowlist can no longer deny it by name. Lock the intended contract: it only appears when allowed MCP tools survive the filter, and its catalog (derived from the already policy-filtered list) can never expose a denied tool. Addresses the ordering observation from the Copilot review on #3342. |

fix(agents): preserve todos state across node updates (#3180)
* fix(agents): preserve todos state across node updates ThreadState.todos had no reducer, so any downstream node returning a partial state without todos was implicitly setting it to None, which LangGraph then used to overwrite the previously streamed value. This caused the to-do list to render correctly during streaming but vanish once streaming completed. Add a merge_todos reducer that keeps the last non-None value, mirroring the merge_artifacts pattern already used in the same file. An explicit empty list is still respected so that 'user cleared todos' works. Tests: 10 new unit tests in tests/test_thread_state_reducers.py covering merge_todos plus regression coverage for merge_artifacts and merge_viewed_images. All 69 thread-related tests pass locally. Closes #3123 * test(agents): add annotation binding regression guard Address Copilot review feedback on #3123: - Add TestThreadStateAnnotations asserting that ThreadState.todos is Annotated with merge_todos. Without this guard, reverting the Annotated[list | None, merge_todos] binding would silently regress #3123 while all existing reducer unit tests continue to pass. - Align test imports to 'from deerflow.agents.thread_state import ...' matching the rest of the backend test suite. |

refactor: split backend into harness (deerflow.*) and app (app.*) (#1131)
* refactor: extract shared utils to break harness→app cross-layer imports Move _validate_skill_frontmatter to src/skills/validation.py and CONVERTIBLE_EXTENSIONS + convert_file_to_markdown to src/utils/file_conversion.py. This eliminates the two reverse dependencies from client.py (harness layer) into gateway/routers/ (app layer), preparing for the harness/app package split. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: split backend/src into harness (deerflow.*) and app (app.*) Physically split the monolithic backend/src/ package into two layers: - **Harness** (`packages/harness/deerflow/`): publishable agent framework package with import prefix `deerflow.*`. Contains agents, sandbox, tools, models, MCP, skills, config, and all core infrastructure. - **App** (`app/`): unpublished application code with import prefix `app.*`. Contains gateway (FastAPI REST API) and channels (IM integrations). Key changes: - Move 13 harness modules to packages/harness/deerflow/ via git mv - Move gateway + channels to app/ via git mv - Rename all imports: src.* → deerflow.* (harness) / app.* (app layer) - Set up uv workspace with deerflow-harness as workspace member - Update langgraph.json, config.example.yaml, all scripts, Docker files - Add build-system (hatchling) to harness pyproject.toml - Add PYTHONPATH=. to gateway startup commands for app.* resolution - Update ruff.toml with known-first-party for import sorting - Update all documentation to reflect new directory structure Boundary rule enforced: harness code never imports from app. All 429 tests pass. Lint clean. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * chore: add harness→app boundary check test and update docs Add test_harness_boundary.py that scans all Python files in packages/harness/deerflow/ and fails if any `from app.*` or `import app.*` statement is found. This enforces the architectural rule that the harness layer never depends on the app layer. Update CLAUDE.md to document the harness/app split architecture, import conventions, and the boundary enforcement test. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add config versioning with auto-upgrade on startup When config.example.yaml schema changes, developers' local config.yaml files can silently become outdated. This adds a config_version field and auto-upgrade mechanism so breaking changes (like src.* → deerflow.* renames) are applied automatically before services start. - Add config_version: 1 to config.example.yaml - Add startup version check warning in AppConfig.from_file() - Add scripts/config-upgrade.sh with migration registry for value replacements - Add `make config-upgrade` target - Auto-run config-upgrade in serve.sh and start-daemon.sh before starting services - Add config error hints in service failure messages Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix comments * fix: update src.* import in test_sandbox_tools_security to deerflow.* Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: handle empty config and search parent dirs for config.example.yaml Address Copilot review comments on PR #1131: - Guard against yaml.safe_load() returning None for empty config files - Search parent directories for config.example.yaml instead of only looking next to config.yaml, fixing detection in common setups Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: correct skills root path depth and config_version type coercion - loader.py: fix get_skills_root_path() to use 5 parent levels (was 3) after harness split, file lives at packages/harness/deerflow/skills/ so parent×3 resolved to backend/packages/harness/ instead of backend/ - app_config.py: coerce config_version to int() before comparison in _check_config_version() to prevent TypeError when YAML stores value as string (e.g. config_version: "1") - tests: add regression tests for both fixes Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix: update test imports from src.* to deerflow.*/app.* after harness refactor Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> |
