(Optional) Switch the agent loop to `claude-agent-sdk` - -DataMind ships two interchangeable agent-loop implementations: - -| Backend | How it talks to the model | When to pick it | -|---|---|---| -| `native` (default) | Pure Python, `anthropic` SDK → your gateway | Simplest deploy, fewest deps | -| `sdk` | `claude-agent-sdk` → `claude` CLI → **CCR** (local translator) → your gateway | Want the SDK's own Subagents / Compaction facilities | - -The role-scoped tool registries (19 read/utility tools for RetrieveAgent and 11 write tools for StoreAgent), the event shape, the frontend, **and DataMind's own safety HookChain** (PathAllowlist / DestructiveSql / AuditLog) all work identically either way — only the inner loop changes. On `native` the HookChain runs at the loop's dispatch chokepoint; on `sdk` it runs inside each MCP tool wrapper. Same chain instance, same Allow/Deny/AskUser/Rewrite decisions, same audit log. - -> Note: the SDK's *own* hook system (its `PreToolUse`/`PostToolUse` API) is a separate thing from DataMind's `HookChain`. DataMind's safety hooks are enforced on both backends regardless of which one you pick. - -### Why CCR - -The SDK always speaks Anthropic's `/v1/messages` protocol. If your upstream gateway only speaks OpenAI `/v1/chat/completions`, put `claude-code-router` (CCR) in the middle — it's a tiny Node process that translates both directions. - -### Start CCR - -```bash -# Install node >= 18.

Pick whichever fits your workflow. - -### 9.1 Agentic storage (recommended for ad-hoc additions) - -StoreAgent owns all writes across the five data surfaces.

See [migration notes](LEGACY_RUNTIME.md). +The supported architecture is Codex over a shared data layer. -## Python facade - -The preferred entry point is `build_datamind`: +## Direct Python data plane ```python -from datamind.agent import build_datamind -from datamind.config import Settings - +from datamind.config import DataSettings +from datamind.data_plane import build_data_plane -async def run() -> None: - settings = Settings() # reads DATAMIND__* environment variables - system = await build_datamind(settings) +async def run(): + data = await build_data_plane(DataSettings(), enable={"graph", "memory", "skills"}) try: - receipt = await system.ingest("Remember that weekly reports use Chinese.") - result = await system.query("What language should weekly reports use?") - print(receipt["receipts"]) - print(result["answer"]) + await data.warmup() + receipt = await data.call("memory_save", {"content": "Weekly reports use Chinese."}) + result = await data.call("memory_recall", {"query": "report language"}, read_only=True) + print(receipt, result) finally: - await system.aclose() + await data.aclose() ``` -`DataMind` also supports the async context-manager form: - -```python -system = await build_datamind(settings) -async with system: - result = await system.query("...") -``` - -### Stable facade methods - -| Symbol | Stability | Contract | -|---|---|---| -| `datamind.agent.build_datamind(settings, enable=None)` | Stable | Builds one `DataMind` facade with shared services and separate Store/Retrieve registries. `enable` may contain `kb`, `db`, `graph`, `skills`, and `memory`. | -| `DataMind.ingest(message, history=None)` | Stable | Runs StoreAgent and returns the StoreAgent result, including `answer`, `receipts`, `tool_trace`, `surfaces_used`, `iterations`, `stop_reason`, and `usage`. | -| `DataMind.query(message, history=None, final_contract=None)` | Stable | Runs RetrieveAgent and returns `answer`, `evidence`, `surfaces_used`, `tool_trace`, `iterations`, `stop_reason`, and `usage`. | -| `DataMind.warmup()` | Stable | Loads profile skills/graph and returns warmup counts plus hook names. | -| `DataMind.aclose()` | Stable | Idempotently closes shared clients, engines, stores, and providers. | -| `datamind.config.Settings` | Stable | Pydantic settings model populated from `DATAMIND__*` variables or `.env.datamind`. | - -The `StoreAgent` and `RetrieveAgent` objects are available as -`system.store_agent` / `system.retrieve_agent` (or the shorter -`system.store` / `system.retrieve` properties). Their public `store`, `query`, -and `warmup` methods are stable convenience methods; loop constructors and -private attributes are not. - -## Result shapes +`DataSettings` and `Settings` name the same typed settings model. +`DataPlane.call(name, arguments, context=None, read_only=False)` validates the +schema, profile and hooks. Business write tools attach receipts. Selecting +surfaces controls which services initialize. No conversation client is created; +KB still requires a configured embedding provider. An explicit `text_client` +parameter is reserved for custom capability pipelines and benchmark fixtures. -The facade returns JSON-serialisable dictionaries so it can be used from a -CLI, HTTP server, or worker without importing a provider model. The important -fields are: +## Codex hosting -### RetrieveAgent result - -```json -{ - "answer": "...", - "evidence": [ - { - "surface": "kb", - "source_id": "file:...", - "locator": {"source": "handbook.md", "chunk_id": "..."}, - "content": "...", - "score": 0.82 - } - ], - "surfaces_used": ["kb", "db"], - "tool_trace": [], - "iterations": 1, - "stop_reason": "end_turn", - "usage": {} -} -``` - -`evidence` is best-effort normalized provenance.

A receipt records -what DataMind observed and attempted; it is not a two-phase commit with an -external database or sink. +`CodexHost` is a transport adapter around the official SDK, not another agent +implementation. `query` binds read-only access; `ingest` permits explicit +writes. `stream` yields `text`, `tool_use`, `tool_result`, and `done` dictionaries. +Completion includes `answer`, `receipts`, `evidence`, `tool_trace`, +`surfaces_used`, `iterations`, `stop_reason`, `usage`, `request_id`, +`workspace_revision` and `recovery`. The iteration count represents observed +data/tool calls, not internal model reasoning iterations. -## NetworkX graph traversal +Actual MCP operations supply request-scoped traces and receipts, including +when SDK Code Mode wraps calls inside a generic execution event. Evidence is +best-effort normalized provenance. Receipts contain `stored`, `unchanged` or +`failed` per-surface outcomes; an ID alone does not mean success. -`NetworkXGraphStore.traverse` returns paths distinguished by their exact stored -edge sequences, not just their node sequences. Parallel relations and the same -relation from distinct origins remain separate evidence paths; relation, -weight, and source properties are preserved. Upserting an existing edge identity -still replaces that edge rather than creating another path. +`CodexSession` is the lower-level official-SDK bridge. Local plugin use does +not require `CodexHost` or a second model key. Gateway and approval settings are +documented in [deployment](CODEX_GATEWAY_DEPLOYMENT.md). -Traversal uses breadth-first expansion in deterministic target/relation/edge-key -order. `relation_filter` applies at every hop, no path repeats a node, and -`max_hops` and `max_results` bound expansion. Non-positive limits return no paths. -Each emitted prefix counts toward `max_results`, so reaching the cap stops -expansion rather than enumerating all combinations of parallel edges. Selected -paths are sorted by descending score; this is not a global top-k guarantee. +## Workspace snapshots -## HTTP API contract +`Workspace.prepare` inventories sources; `Workspace.publish` builds and atomically +publishes selected KB/DB/Graph snapshots from prepared, source-hashed inputs. +`Workspace.reader(revision=...)` selects immutable historical snapshots; +`enable` may select a subset of that manifest's surfaces. `reader.call` enforces +read-only access. Query hosting selects the current head at request admission; +without a published head, it reads independent live stores. Direct writes do +not silently modify snapshots. Memory/Skills are not one atomic business snapshot. -The bundled FastAPI app is a thin transport over the same facade. Request body -for `/api/ask` and `/api/store`: +## HTTP API ```json {"message": "...", "history": []} ``` -| Route | Stable response | +| Route | Contract | |---|---| -| `GET /api/health` | `status`, active profile, LLM protocol/model, enabled tool counts, and StoreAgent revision | -| `GET /api/tools` | `{ "tools": [...], "count": N }`; each item includes role, surface, access, description, group, and input schema | -| `POST /api/ask` | `AskResponse` containing the RetrieveAgent result fields | -| `POST /api/store` | `AskResponse` containing the StoreAgent result fields, including receipts | -| `POST /api/chat` | `text/event-stream`; each frame is `{ "type": ..., ... }` with `text`, `tool_use`, `tool_result`, `error`, or `done` events | -| `POST /api/upload` | Saved filename/path metadata and suggested StoreAgent prompts; upload alone does not ingest data | - -`/api/kb/reindex`, `/api/kb/documents`, `/api/memory/{namespace}`, and -`/api/graph/stats` are inspection/compatibility routes.

Inspection/reindex routes +remain available; KB routes require a configured provider. Memory inspection +is limited to the active profile. `X-Session-Id` scopes conversation and is not +an authentication credential. See [security boundaries](SECURITY_BOUNDARIES.md). + +## Graph traversal + +NetworkX traversal distinguishes exact stored edge sequences, including +parallel relations and different origins. Breadth-first expansion is bounded +by `max_hops` and `max_results`; relation filters apply at every hop, and paths +do not repeat nodes. Deterministic expansion and score sorting do not promise +a global top-k result. Sources and edge properties remain attached to paths. ## Compatibility policy -- Patch releases fix bugs and improve diagnostics without changing the stable - result fields or role boundary. -- Minor releases may add optional fields, tools, providers, or routes. Consumers - should ignore unknown JSON fields and unknown SSE event types. -- Major releases may change stable contracts and require migration notes. -- The StoreAgent write/read separation and RetrieveAgent read-only guarantee are - security-relevant API behavior, not prompt conventions. +Minor releases may add fields and tools; consumers should ignore unknown JSON +fields and SSE events.
