Changelog

[Unreleased]

Added

• v0.2 PR #1 — Postgres migration: production backing store switched from SQLite to PostgreSQL 16 ahead of M8-Py (FastAPI) per DR-2.
  • pyproject.toml: asyncpg>=0.30 + psycopg[binary]>=3.2 + langgraph-checkpoint-postgres>=2.0.0 added to runtime; aiosqlite>=0.20 moved to [dependency-groups].dev (test-only); langgraph-checkpoint-sqlite removed.
  • src/my_deepagent/persistence/db.py: dialect-aware connect listener — SQLite still gets WAL + busy_timeout=5000 + foreign_keys=ON, Postgres gets SET TIME ZONE 'UTC'. New Database.dialect_name property + drop_schema method for tests.
  • src/my_deepagent/persistence/checkpointer.py: SqliteSaver → AsyncPostgresSaver. API is now async (async with) and takes a connection string; SQLAlchemy URL prefixes (postgresql+asyncpg://, postgresql+psycopg://) are auto-stripped to a plain libpq DSN. New _to_psycopg_dsn helper covered by 4 unit tests.
  • src/my_deepagent/persistence/upsert.py (new): insert_for(session) — dialect-aware UPSERT helper. Picks postgresql.insert or sqlite.insert based on the bound engine's dialect. Replaces 5 hardcoded sqlite_insert call sites in budget.py, recovery.py, and cli/doctor.py.
  • src/my_deepagent/config.py: database_url default switched from sqlite+aiosqlite:///<data_dir>/database.sqlite3 to postgresql+asyncpg://devflow:devflow@localhost:55432/mydeepagent. The v3 devflow DB is preserved untouched; v4 lives in a fresh mydeepagent DB.
  • src/my_deepagent/persistence/models.py: RunRow.__table_args__ partial unique index now declares both postgresql_where= and sqlite_where= so the index is partial on both dialects.
  • src/my_deepagent/cli/doctor.py: check 8 (disk+db) is now dialect-aware — Postgres path runs SELECT 1 (pg_isready equivalent: proves reachability + auth + DB exists); SQLite path keeps PRAGMA integrity_check. Doctor docstring updated.
  • alembic/env.py: env-aware URL resolution — MYDEEPAGENT_DATABASE_URL > DATABASE_URL > Postgres default. Async driver prefixes (+asyncpg, +aiosqlite) are mapped to the sync equivalents alembic needs (+psycopg, plain sqlite).
  • alembic/versions/9f2a6c79667e_v0_2_baseline_schema_postgres.py (new): fresh baseline autogenerated against live Postgres. Old SQLite baseline 79945fdc2649 + partial-index migration 839f2233e346 deleted.
  • tests/conftest.py (new): pg_db_url async fixture. Creates a fresh Postgres database per test (against docker-compose devflow-postgres) via the maintenance postgres DB; drops on teardown after terminating any lingering backends. Used by the E2E suite and the new checkpointer tests.
  • tests/integration/test_checkpointer.py: rewritten for AsyncPostgresSaver (4 pure DSN-converter tests + 3 async context-manager tests).
  • tests/integration/test_e2e_workflow.py: switched from sqlite+aiosqlite tmp_path to pg_db_url. Real OpenRouter E2E now exercises the production Postgres path end-to-end (~122 s, ~$0.05/run).

Migration trigger (per DR-2)

• The bound is two concurrent writers on runs / run_phases / llm_calls. Today the CLI is the only writer — but M8-Py (FastAPI) introduces a second one, and SQLite WAL allows only a single concurrent writer. Doing the move before M8-Py lands gives the test surface time to harden.
• Recovery: previous SQLite database at ~/Library/Application Support/my-deepagent/database.sqlite3 (macOS) / $XDG_DATA_HOME/my-deepagent/database.sqlite3 is not migrated — v0.1.0 was the only release that wrote to it and v0.2 starts a fresh history. Set MYDEEPAGENT_DATABASE_URL=sqlite+aiosqlite:///<path> to read the legacy file if needed.

Gates

• ruff check + ruff format --check + mypy --strict: PASS (102 source files)
• pytest non-E2E: 576 PASS (5.46 s) — bulk on sqlite tmp_path, new checkpointer suite on Postgres pg_db_url
• pytest E2E real OpenRouter: 1 PASS (122.93 s) on Postgres backend

[0.1.0] - 2026-05-16

First tagged milestone of the Python rewrite. The pre-Python-rewrite TypeScript monorepo has been removed (commit 0e61b2d); recovery is available via the pre-python-rewrite tag at c9fed71.

Added

• Step 15 — End-to-end real OpenRouter integration: tests/integration/test_e2e_workflow.py runs spec-and-review@1 workflow (spec → review → verify) end-to-end against real OpenRouter DeepSeek in ~76s for ~$0.05 per run. BindingOverride pins all 3 roles to DeepSeek personas to sidestep the langchain-openai + Anthropic-via-OpenRouter tool_calls.args JSON-string ValidationError (known v0.1.0 limit). New seed personas: openrouter-deepseek-spec-writer@1 (capabilities: spec_write, phase_planning; max_cost_per_call_usd=0.01) and openrouter-deepseek-code-reviewer@1 (capabilities: code_review, evidence_check; max_cost_per_call_usd=0.01). Persona count test updated to 12. WorkflowEngine._build_envelope now inlines the artifact JSON Schema directly in the prompt so the LLM sees exact required fields. WorkflowEngine._record_llm_call fills every NOT NULL LlmCallRow column (thread_id, persona_version, role, turn_index, cached_tokens, reasoning_tokens, cost_usd_input/output, etc.). CostMiddleware now probes both usage_metadata and response_metadata.token_usage (prompt_tokens / completion_tokens fallback) to capture OpenAI-compatible streamed responses forwarded by OpenRouter.
• Step 12 — Doctor full 8-check + OpenRouter pricing fetch: mydeepagent doctor now runs 8 checks (python / uv / git / workspace_root / config+governance / openrouter_api_key / openrouter_ping + pricing upsert / disk+sqlite integrity). mydeepagent pricing lists the cached OpenRouter pricing matrix from the persisted model_pricing table. mydeepagent run preview now reads from the persisted model_pricing table when populated, falling back to the static seed otherwise. 26 new tests (23 unit + 3 integration).
• Step 11 — Audit log + secret scrubbing: append-only {state_dir}/audit.jsonl recording every tool call (name/args/duration/error). AuditToolMiddleware now ships with a built-in JSONL recorder (file_recorder), attached automatically in WorkflowEngine and Interactive REPL. structlog configured project-wide via my_deepagent.logging.configure_logging, with a _scrub_processor that redacts OpenRouter / Anthropic / OpenAI / LangSmith / GitHub / GitLab API keys plus generic Bearer tokens before they reach stderr or JSON sinks. audit.py provides append_audit_record (O_APPEND, 0o600 permissions), read_audit_records (with optional limit, corrupt-line skip), and make_audit_recorder async factory. 19 new tests (8 audit unit, 9 logging unit, 3 audit-middleware integration).
• Step 10 — Interactive REPL: mydeepagent (no subcommand) launches a prompt_toolkit REPL with --agent / --model overrides, slash commands (/help, /quit, /exit, /agent, /model, /clear, /stats, /budget, /runs), file refs (@path/to/file.py expansion with repo-root containment check), and CostMiddleware-wired agent calls so spending is metered per interactive session. slash.py implements parse_slash + SlashRegistry. CostMiddleware gains interactive_session_id parameter. 21 new tests (10 slash unit, 5 file-ref unit, 3 CLI integration, 3 updated CLI unit).
• Step 9 — Crash recovery + concurrency: sweep_orphan_runs(db) in my_deepagent.recovery marks non-terminal runs/phases as failed at app startup so active-run uniqueness slots (partial unique index ux_active_run_repo_base) are freed; mydeepagent runs list/show/resume CLI in my_deepagent.cli.runs (list with optional --state filter, show by full UUID or 6+ char prefix, resume stub with exit-2 hint); SIGTERM/SIGINT graceful shutdown in WorkflowEngine (install_signal_handlers, _on_signal, _force_cancel_inflight; 30s grace then cancel in-flight tasks); auto-sweep on mydeepagent run before any new phase begins. 21 new tests.
• Step 8 — Budget guardrails: BudgetTracker (SQLite WAL ledger via BudgetLedgerRow, on_hit policy block/warn_continue/prompt, per-run + per-day + per-persona-daily scopes) in my_deepagent.budget; cost preview before mydeepagent run (rich table with per-phase est.) via my_deepagent.monitoring.cost_estimator; CostMiddleware integrated with BudgetTracker (pre-call assert + post-call record); WorkflowEngine accepts optional budget_tracker and pricing kwargs (backward- compatible); CLI: mydeepagent budget (ledger), mydeepagent stats --by model|persona|day, mydeepagent costs (alias); --no-preview flag on mydeepagent run. 28 new tests.
• Step 7 — Workflow engine: WorkflowEngine in my_deepagent.engine orchestrates phase loop, artifact watcher (write_file/edit_file detection), jsonschema validation with one repair retry, approval gate, and final report compose (JSON + Markdown). ArtifactWatcherMiddleware in my_deepagent.middleware.artifact_watcher intercepts write_file/edit_file tool calls targeting the expected artifact path. RunEventType + run_idempotency_key in my_deepagent.run_event (closed event set, deterministic idempotency keys per plan v2.0 §13.1). cli/run.py exposes mydeepagent run <workflow.yaml>. tui/approval.py prompts the user for approve/reject/request_changes/abort. FK-safe persistence: WorkflowTemplateRow and AgentPersonaRow upserted before RunRow to satisfy SQLite FK ordering constraints. 18 new tests: 12 engine unit/integration tests + 6 artifact watcher tests.
• Step 6 — Distribution: mydeepagent init/login/logout/keys/doctor CLI commands; platformdirs-based data dirs; OS keyring (macOS Keychain / Linux Secret Service / Windows Credential Store) for API keys via my_deepagent.keys; first-run governance consent in governance.py; secret resolution priority (config → env → keyring → error) in my_deepagent.secrets; i18n catalog (ko / en) under my_deepagent.i18n controlled by MYDEEPAGENT_LANG.
• persistence/models.py (P0-1): partial unique index ux_active_run_repo_base on runs(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); only get_checkpointer_ctx context 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 integration pytest 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 permissions block from all 10 seed personas; SafetyShellMiddleware now enforces destructive-command + secret-path policy at the tool layer for local_shell backend agents.
• build_agent automatically prepends SafetyShellMiddleware to every agent and skips permissions kwarg when deepagents_backend == "local_shell".
• SafetyShellMiddleware extended with secret-path enforcement: read_file/write_file/edit_file/ls tool calls are blocked when file_path/path matches any DENY_PATH_PATTERNS glob (wcmatch GLOBSTAR|IGNORECASE|DOTGLOB).
• All env vars require MYDEEPAGENT_ prefix (e.g. MYDEEPAGENT_OPENROUTER_API_KEY, MYDEEPAGENT_BUDGET_DAILY_USD). .env.example updated 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()).

Known limitations (v0.1.0)

• usage_metadata is sometimes empty for responses forwarded by OpenRouter (deepagents wraps the underlying ChatOpenAI response so token counts may not surface). The CostMiddleware recorder still fires and a LlmCallRow row is persisted, but input_tokens / output_tokens may read as 0 — the E2E test treats this as a known limit. v0.2 will probe more response shapes (raw chunks / callbacks).
• Anthropic models via OpenRouter currently fail with a tool_calls.args JSON-string vs dict ValidationError inside langchain-openai. Workaround: pin DeepSeek personas via BindingOverride. Tracking for v0.2.
• mydeepagent runs resume <run_id> is a stub (exit-2 hint only); workflow replay from a half-run state is not yet implemented.
