fix(session): forward overwrite to SqliteSessionStore imported-session save

The merged import contract (#5547) now calls _save_imported_session(session, overwrite=overwrite), but SqliteSessionStore's override kept the old single-arg signature and raised TypeError, breaking every indexed portable import. Forward the keyword to the parent and update the concurrency test's save shim to mirror the signature. Co-authored-by: Mervin Praison <[email protected]>

 > [!IMPORTANT]
 > **Agents only recognize parameters.** When creating tools, always expose all options as function parameters—agents cannot discover env vars or config files.

-> [!IMPORTANT]
-> **Vendor / third-party API tools:** New integrations (external APIs, datasets, SaaS wrappers) belong in **[PraisonAI-Tools](https://github.com/MervinPraison/PraisonAI-Tools)** as optional pip plugins — **not** as new `praisonaiagents/tools/*_tools.py` files in this repo. Core `praisonaiagents/tools/` holds SDK primitives (decorator, registry, schedule, shell, trust, subagent) and a small set of **legacy** bundled tools kept for backward compatibility. Do not treat legacy search tools (e.g. Tavily/Exa) as precedent for adding new vendor modules here. See §6.1.1 for the full routing test.
-
-#### 6.1.1 Tool routing — third-party connectors → PraisonAI-Tools (MUST)
-
-New agent-callable third-party connectors (external HTTP/API, SaaS, DB) go to **[PraisonAI-Tools](https://github.com/MervinPraison/PraisonAI-Tools)**, NOT `praisonaiagents/tools/`. Core keeps only tool *protocols, base classes, decorator, registry, resolver, trust/fencing* — not connectors.
-
-**Decision test** — keep in core only if **both** left-column conditions hold; route out if **any** right-column condition holds:
-
-| Keep in core `praisonaiagents/tools/` | Route to PraisonAI-Tools |
-|---|---|
-| Local-state only (filesystem, shell, Python, AST, todo, schedule) **or** framework plumbing (delegation, subagent, session, artifact, memory, clarify) | Calls a third-party/remote API or SaaS |
-| …using only stdlib or already-required core deps | Needs service-specific auth or SDK; is a vendor connector (search, data, CRM, DB, messaging) |
-
-A macro/FX data client (e.g. FXMacroData) → **PraisonAI-Tools**, even on stdlib `urllib`, because it depends on an external service + credentials.
-
-> [!WARNING]
-> Legacy in-repo connectors (`tavily_tools.py`, `exa_tools.py`, `github_tools.py`, etc.) are backward-compat precedent, **not** a licence to add more. "Same shape as Tavily/Exa" is a *consistency* check, not a *routing* one — do not approve a new connector into core on precedent alone.
-
-Connectors in PraisonAI-Tools are used via `Agent(tools=[...])`. Placement/registration alone does **not** fence results — fencing requires the tool name in `EXTERNAL_TOOL_NAMES` or `ToolTrustLevel.EXTERNAL`. Register with `add_external_tool(tool_name)` to fence untrusted results.

-# SDK Behavior Matrix
-
-Deterministic expectations for the public knobs that integrators most often mistake for
-"model randomness". Each row lists a related test. Passing it is a useful check, but mocked
-unit tests do not rule out SDK bugs in the paths they replace. If your app disagrees with a
-row, check the sharp edges and investigate the real call path.
-
- **Scope:** `praisonaiagents` Python API (main branch). Paths are relative to
-  `src/praisonai-agents/`.
- **Source of truth:** code + the listed tests. If a docstring disagrees with this page,
-  trust the test, then fix whichever is stale.
-
-## How to use
-
-1. Find the knob from the report in the tables below.
-2. Run the listed test: `PYTHONPATH=. python -m pytest <test> -q`.
-3. **Test fails** → SDK defect; open a bug. **Test passes** but behavior differs → check the
-   *Sharp edge* column, reproduce on the real call path, then open a bug or update this page.
-
---
-
-## 1. Chat & streaming
-
-Streaming is configured through `output=`, not a constructor kwarg.
-`Agent(stream=True)` raises `TypeError` with the hint
-*"streaming moved into output=; use output=OutputConfig(stream=True)."*
-`agent.stream` is `False` unless `output="stream"` or `OutputConfig(stream=True)` is used.
-
-| API / knob | Expected behavior | Sharp edge | Test |
-| --- | --- | --- | --- |
-| `chat(prompt, stream=None)` | Inherits `agent.stream`. Returns the final `str` (or model, see §3). | Never a generator. | `tests/unit/agent/test_execution_api.py` |
-| `chat(stream=True)` | Tokens go to `agent.stream_emitter`; the call still returns the full `str`. If the adapter cannot stream (`"Streaming is not supported"`) or the stream attempt fails transiently, it falls back to a non-streaming call. | `None` is **not** a valid "streaming succeeded" result (#5737). `LLMError`, `ToolExecutionError`, other `ValueError`s and post-dispatch tool-turn failures are **not retried** by the fallback. Of these, only `ToolExecutionError` reaches the caller; the rest roll back history and `chat()` returns `None` (see below). | `tests/test_chat_explicit_stream_fallback.py`, `tests/test_streaming_fallback_kwargs.py` |
-| `chat(stream=False)` | Single non-streaming completion; no stream events. | — | `tests/unit/test_stream_preset.py` |
-| `start(prompt)` | Stream priority: explicit kwarg > `agent.stream` > TTY. When streaming, returns a **generator** of chunks; otherwise a `str`. | Because `agent.stream` is always a bool, the TTY fallback only applies if `agent.stream` is set to `None`. Output guardrails are not applied to streamed chunks. | `tests/unit/agent/test_execution_api.py` |
-| `run(prompt)` | Never streams unless `stream=True` is passed; returns `str`. | Ignores TTY. | `tests/unit/agent/test_execution_api.py::TestAgentRunMethod::test_run_ignores_tty_detection` |
-| `iter_stream(prompt)` | Always a generator of chunks. | — | `tests/unit/agent/test_execution_api.py::TestAgentIterStreamMethod::test_iter_stream_always_streams` |
-| `achat()` / `astart()` | Same `stream` resolution as `chat()`; awaits and returns the final `str`. | Unlike `start()`, `astart()` never returns an (async) generator. | `tests/unit/agent/test_achat_unified_dispatch.py`, `tests/unit/agent/test_execution_api.py::TestAsyncMethods::test_astart_streams_in_tty` |
-
-**When `chat()`/`achat()` return `None`:** input guardrail or `BEFORE_AGENT` hook blocked the
-run, or the LLM call failed with anything other than `ToolExecutionError` (history is rolled
-back and the error is displayed/logged, not raised). Check for `None` rather than relying on
-`try/except` around `chat()`.
-An **output** guardrail rejection returns a fixed refusal string, not `None`; see
-`agent.last_guardrail_error`.
-
-## 2. Memory prefetch & scope
-
-| API / knob | Expected behavior | Sharp edge | Test |
-| --- | --- | --- | --- |
-| `MemoryConfig(prefetch=True)` — sync (`_prefetch_memory`) | Before each turn, searches long-term memory with up to 5 terms (verbatim prompt → significant words → salient single words), stopping at the first non-empty hit. Results are injected into the **system prompt** under `## Recalled memories`, capped by `prefetch_limit` (5) and `prefetch_token_budget` (512, truncated with `…`). | Off by default. Errors are swallowed (debug log) and inject nothing. | `tests/unit/memory/test_prefetch.py` |
-| Same — async (`_aprefetch_memory`) | Same terms, stop rule, scope and formatting via `asearch_memory`. | Backends with only `.search()` (no `search_long_term`) are searched by the sync path but not the async path. | `tests/unit/memory/test_prefetch.py::test_async_prefetch_falls_back_to_significant_tokens` |
-| `MemoryConfig(user_id=...)` | Agents sharing a `user_id` share a store and recall each other's turns. Search is scoped by `user_id` + `session_id`, not `agent_id`. | Without `user_id`, each Agent gets a random `agent-<uuid>` id (warning logged) — memory is **isolated per instance**. There is no `Agent(user_id=...)` kwarg. | `tests/test_memory_cross_session.py` |
-
-## 3. Structured output
-
-`output_pydantic` / `output_json` are per-call `chat()`/`achat()` kwargs (forwarded by
-`start()`/`run()`) and `Task` fields — not `Agent` constructor params. There is no
-`output_json_schema`. Native `response_format` is used when the model supports structured
-outputs; otherwise the schema is appended to the prompt as text.
-
-| API / knob | Expected behavior | Sharp edge | Test |
-| --- | --- | --- | --- |
-| `chat(..., output_pydantic=Model)` | Returns a `Model` **instance** (tries strict JSON, fenced ```json, then first `{...}` in prose). | On parse failure, logs a warning and returns the **raw string** — no exception, no retry. Check `isinstance`. | `tests/unit/agents/test_chat_output_pydantic_coercion.py` |
-| `chat(..., output_json=Model)` | Returns a JSON **string**. | Never a `dict` — call `json.loads` yourself. | `tests/unit/agents/test_chat_output_pydantic_coercion.py::test_chat_output_json_stays_string` |
-| `Task(output_pydantic=Model)` in a team | `TaskOutput.pydantic` holds the instance; `output_format="Pydantic"`. | Fails closed: invalid output is a failed task (`Structured output validation failed ...`), which drives the retry loop. Setting both `output_json` and `output_pydantic` raises `ValueError`. | `tests/unit/agents/test_output_pydantic_policy.py` |
-| `Task(output_json=Model)` in a team | `TaskOutput.json_dict` holds the parsed `dict`; `output_format="JSON"`. | Same fail-closed rule. | `tests/unit/agents/test_output_pydantic_policy.py::test_output_json_prose_is_not_success` |
-| Native vs text schema | `response_format` (strict) for capable models; prompt injection otherwise. | Provider-dependent. | `tests/test_native_structured_outputs.py` |
-
-## 4. Teams & handoff
-
-| API / knob | Expected behavior | Sharp edge | Test |
-| --- | --- | --- | --- |
-| `AgentTeam(agents, tasks=[Task, ...])` | Accepts a list/tuple of `Task`. Sequential tasks are chained. `start()` returns the last task's `.raw` string (`return_dict=True` → `{"task_status", "task_results"}`). | `tasks="..."` → `TypeError: AgentTeam.tasks must be a list of Task instances, not str. ...`; `tasks=[]` → `ValueError: If tasks are provided, at least one task must be present`; non-`Task` item → `TypeError: tasks[i] must be a Task instance, got <type>`. | `tests/unit/agents/test_agentteam_task_validation.py` |
-| `AgentTeam(agents)` (no tasks) | One task auto-generated per agent. | Empty `agents` fails at `start()`, not construction. | `tests/unit/agents/test_agentteam_task_validation.py::test_tasks_none_auto_generates` |
-| `Agent(handoffs=[other])` | Adds a `transfer_to_<name>` tool; the model decides whether to call it. Tool returns `"Handoff successful. <name> response: ..."`. | The model may not call the tool — that is a prompt issue, not a crash. Cycles/depth (`max_depth=10`) return an `"Error: ..."` string to the model rather than raising. Timeout (300 s) applies to async handoffs only. | `tests/test_handoff_compatibility.py`, `tests/unit/test_handoff_unified.py` |
-
-## 5. AG-UI
-
-| API / knob | Expected behavior | Sharp edge | Test |
-| --- | --- | --- | --- |
-| `AGUI(agent=...).get_router()` | Returns a FastAPI `APIRouter`; mount it with `app.include_router(...)`. `POST {prefix}/agui` → SSE (`text/event-stream`); `GET {prefix}/status` → `{"status": "available"}`. | AGUI has no built-in server or default port — you run uvicorn and own startup/shutdown. `AGUI()` with no agent raises `ValueError`. | `tests/agui/test_agui.py`, `tests/agui/test_router.py` |
-| SSE events | `RUN_STARTED` → `TEXT_MESSAGE_*` / `TOOL_CALL_*` → `RUN_FINISHED`; exceptions become `RUN_ERROR`. | Multi-agent (`agents=`) sends the whole result as one text message, not token stream. Event order and `RUN_ERROR` emission over the endpoint are **not pinned** by a test; the router test only checks that a failing agent still yields HTTP 200. | `tests/agui/test_streaming.py::TestRunLifecycleEvents` (event construction), `tests/agui/test_router.py::TestAGUIEndpointErrorHandling::test_agui_endpoint_handles_agent_error` (HTTP only) |

praisonai-triage-agent[bot]andMervin Praison	43724ab962	fix(session): forward overwrite to SqliteSessionStore imported-session save The merged import contract (#5547) now calls _save_imported_session(session, overwrite=overwrite), but SqliteSessionStore's override kept the old single-arg signature and raised TypeError, breaking every indexed portable import. Forward the keyword to the parent and update the concurrency test's save shim to mirror the signature. Co-authored-by: Mervin Praison <[email protected]>	2026-10-02 13:55:11 +00:00
