Python rewrite of the agent harness on top of deepagents 0.6.1 + langchain 1.x, replacing the abandoned TS attempt in packages/. 388 unit/integration tests pass. Steps ----- 0. Scaffolding — uv workspace, ruff/mypy/pre-commit/alembic, src/tests/docs trees with docs/schemas/ seeded from my-deepagent-seed/. 1. Core — config (pydantic-settings with MYDEEPAGENT_ env prefix and TOML source), enums (Backend, Capability, RiskLevel, ApprovalDecisionAction, ApprovalState, RunState, RunPhaseState, SessionState, ErrorClass), errors (MyDeepAgentError + BudgetExhaustedError with PEP-3134 cause + context suppression), hash (canonical JSON + sha256). 2. Persona/Workflow/Binding — pydantic v2 schemas with tuple-based deep immutability (post-construction hash drift prevented), YAML loaders, deterministic auto-select (preferred_backends → version → name → hash), override resolution with ineligibility diagnostics, PersonaConsentStore with fcntl.flock + tmp+fsync+rename atomic write. 3. Artifact schema registry — Draft202012Validator, multi-root resolution, structured ValidationFinding output. 4. Persistence — 18 SQLAlchemy 2.0 async ORM models with FK CASCADE/RESTRICT, WAL + busy_timeout + foreign_keys PRAGMA, alembic baseline + ux_active_run_repo_base partial unique index, LangGraph SqliteSaver as context manager only (lifecycle safety). 5. DeepAgent session — build_agent wires Persona → create_deep_agent with LocalShellBackend / FilesystemBackend / StateBackend / CompositeBackend, ChatOpenAI(base_url=openrouter) for openrouter: model strings, and 4 middleware classes (cost / audit-tool / safety-shell / fallback-model). Critical workarounds -------------------- - deepagents 0.6.1 rejects FilesystemPermission together with backends that implement SandboxBackendProtocol (LocalShellBackend). SafetyShellMiddleware enforces destructive-command and secret-path policy at the tool layer instead, and build_agent strips the permissions kwarg when the persona's deepagents_backend is local_shell. - FilesystemOperation in deepagents is Literal['read', 'write'] only; _map_operations collapses our richer schema (read/write/edit/ls) safely. Real OpenRouter smoke --------------------- test_openrouter_deepagents_local_shell_smoke calls DeepSeek via deepagents + LocalShellBackend + SafetyShellMiddleware end-to-end. PASS, ~$0.000001 cost, input=9 / output=1 tokens with content "OK". Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Changelog
[Unreleased]
Added
- persistence/models.py (P0-1): partial unique index
ux_active_run_repo_baseonruns(repo_path, base_branch) WHERE state NOT IN ('completed','failed','aborted')— prevents duplicate active runs per repo/branch - persistence/models.py (P0-3): FK constraints added to
RunRow.template_id(RESTRICT),RunBindingRow.persona_id(RESTRICT),InteractiveSessionRow.persona_id(RESTRICT),RunEventRow.phase_id(CASCADE),ApprovalRequestRow.phase_id(CASCADE),ArtifactRow.phase_id(CASCADE),ToolCallRow.run_id/phase_id/interactive_session_id(CASCADE),LlmCallRow.run_id/phase_id/interactive_session_id(CASCADE),PhaseFeedbackRow.run_id/phase_id(CASCADE) - alembic/versions/839f2233e346: new migration adding partial unique index and all FK constraints above; uses SQLite table-rebuild pattern with PRAGMA foreign_keys=OFF/ON guard
- persistence/checkpointer.py (P0-4): removed
get_checkpointer(leaking connection helper); onlyget_checkpointer_ctxcontext manager is now exported - tests/integration/test_checkpointer.py: 5 tests for checkpointer ctx lifecycle (file creation, parent dir, connection cleanup, lock-free concurrent use)
- tests/integration/test_persistence.py: 7 new P0 verification tests (active-run partial index blocks/allows, cascade-delete of phase_feedback+run_phases, RESTRICT on template delete, index exists in sqlite_master)
- tests/unit/test_session.py: full rewrite to deepagents dataclass API — FilesystemPermission attribute access (.mode/.paths/.operations), build_backend type dispatch (5 cases), _map_operations deduplication (8 cases), _spec_to_permission mapping, updated _subagent_to_dict and _resolve_openrouter_api_key tests; 47 unit tests total
- tests/integration/test_openrouter_smoke.py: real OpenRouter/DeepSeek smoke test (3 tests, ~$0.001-$0.003/run, max_tokens=50); skipped automatically when no API key is configured; validates ChatOpenAI response, usage_metadata tokens, and deepagents CompiledStateGraph end-to-end
- pyproject.toml: registered
integrationpytest marker to silence --strict-markers error - v0.1.0 scaffolding (Step 0): src/tests/docs trees, ruff/mypy/pre-commit/alembic config
- Seed assets copied to docs/schemas/ (personas/workflows/artifacts validated)
- Core module (Step 1): config, enums, errors, hash + unit tests
- Persona / Workflow / Binding module (Step 2): pydantic schemas, YAML loaders, deterministic auto-select, override, consent store with atomic write
- Step 1 review patches (P0/P1): exception chain context suppression, classmethod LSP fix, workspace_root realpath canonicalization, config_invalid error mapping
Changed
- deepagents 0.6.1 LocalShellBackend + permissions conflict workaround: removed
permissionsblock from all 10 seed personas;SafetyShellMiddlewarenow enforces destructive-command + secret-path policy at the tool layer for local_shell backend agents. build_agentautomatically prependsSafetyShellMiddlewareto every agent and skipspermissionskwarg whendeepagents_backend == "local_shell".SafetyShellMiddlewareextended with secret-path enforcement:read_file/write_file/edit_file/lstool calls are blocked whenfile_path/pathmatches anyDENY_PATH_PATTERNSglob (wcmatch GLOBSTAR|IGNORECASE|DOTGLOB).- All env vars require
MYDEEPAGENT_prefix (e.g.MYDEEPAGENT_OPENROUTER_API_KEY,MYDEEPAGENT_BUDGET_DAILY_USD)..env.exampleupdated accordingly. This isolates my-deepagent's env namespace from other tools. - Persona / Workflow / FilesystemPermission models now store list-valued fields as tuples (deep immutability — prevents post-construction mutation that would invalidate compute_hash()).
