fix(review): adopt every documented backend protocol, not just get_response

Review found the Agent(llm=<object>) fix was incomplete, and it was right. Verified by running it: chat_completion-only backend -> self.llm=<object> custom=False BUG get_response backend -> self.llm="custom/..." custom=True ok llm/protocols.py documents two more backend surfaces besides get_response: LLMProviderProtocol via chat/achat, and UnifiedLLMProtocol via chat_completion/achat_completion. A backend implementing either still fell through to the plain OpenAI branch, where the object became the model identifier and the turn went to the wrong backend -- the same defect the branch was added to fix, for a different protocol. Detection now duck-types across all of them. Five tests, including two controls: a plain object with no backend method is still NOT adopted, and a string llm is unaffected.

Read ALL comments above from Gemini, Qodo, CodeRabbit, and Copilot carefully before responding.\n\n**MANDATORY READ (before reviewing):**\n- Always read src/praisonai-agents/AGENTS.md\n- If this PR touches src/praisonai-ts/, also read src/praisonai-ts/AGENTS.md §2.1.2 (TS triage + PR review checklist)\n\n**Phase 1: Review per AGENTS.md**\n1. Protocol-driven: check heavy implementations vs core SDK\n2. Backward compatible: ensure zero feature regressions\n3. Performance: no hot-path regressions\n4. SDK value: review in depth whether the change genuinely adds value to the SDK — never add features for the sake of adding them. It must strengthen the SDK (simpler, more user-friendly, robust, world-class, secure). If it does not clearly add value, request changes or recommend rejecting/closing rather than merging scope creep\n5. Do not bloat the Agent class with additional params — only if absolutely required; we already support many params.\n6.

+  '@claude You are the FINAL architecture reviewer. If the branch is under MervinPraison/PraisonAI (not a fork), you are able to make modifications to this branch and push directly. SCOPE: Review changes in this PR. Python SDK: praisonaiagents, praisonai. TypeScript SDK: src/praisonai-ts/. Do NOT modify src/praisonai-rust. Read ALL comments above from Gemini, Qodo, CodeRabbit, and Copilot carefully before responding.\n\n**MANDATORY READ (before reviewing):**\n- Always read src/praisonai-agents/AGENTS.md\n- If this PR touches src/praisonai-ts/, also read src/praisonai-ts/AGENTS.md §2.1.2 (TS triage + PR review checklist)\n\n**Phase 1: Review per AGENTS.md**\n1. Protocol-driven: check heavy implementations vs core SDK\n2. Backward compatible: ensure zero feature regressions\n3. Performance: no hot-path regressions\n4. SDK value: review in depth whether the change genuinely adds value to the SDK — never add features for the sake of adding them. It must strengthen the SDK (simpler, more user-friendly, robust, world-class, secure). If it does not clearly add value, request changes or recommend rejecting/closing rather than merging scope creep\n5. Do not bloat the Agent class with additional params — only if absolutely required; we already support many params.\n6.

-# Why this exists
-#
-# praisonai-agents has ~11,900 tests. Until this gate, CI executed 15 of them:
-# one smoke step in test-optimized.yml naming two files. Everything else was
-# collected by nobody.
-#
-# The cost of that showed up as two test modules that could not even be
-# IMPORTED -- they referenced symbols moved or replaced months earlier, so 19
-# tests silently contributed nothing while still appearing to exist. A failing
-# test is loud; a test that never collects is not.
-#
-# This job started as collection-only, because running the suite would have gone
-# red on arrival: 297 pre-existing failures nothing had been enforcing, and a job
-# that is red the day it lands teaches people to ignore it. Then a curated
-# green-set, ratcheted upward.
-#
-# Both are gone. The unit suite now runs in full and passes: 9373 tests, 0
-# failures. The `collect` job stays because it is the cheaper, stricter signal --
-# it cannot pass while a test file is unimportable, and it says so in 40s.

    Harbor Container → `praisonai code -p --output json "TASK" --dangerously-skip-approval`

 Notes:
-    - `--dangerously-skip-approval` registers an always-approve backend on the
-      approval registry (plus PRAISON_APPROVAL_MODE=auto /
-      PRAISONAI_TOOL_SAFETY=off) so the assistant runs fully autonomously in the
-      container. Before that registry wiring existed the flag left every
-      critical-tool prompt in place and the non-TTY container auto-denied all of

-      exiting 0 -- one cause of the 0.000 scores in #3932.

-> **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`.

-| --- | --- | --- | --- |
-| `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) |

-    1. No event loop exists - use asyncio.run()
-    2. Event loop already running - avoid deadlock by running the coroutine
-       to completion in a dedicated thread with its own event loop.
-
-    This is a live production helper on the sync tool-calling path (see

+    UnifiedExecutionMixin is unused and scheduled for removal (Issue #2644).
+    None of its methods are invoked by production code: the live execution paths
+    use ``_chat_impl`` / ``_execute_unified_chat_completion`` (in ``chat_mixin.py``)
+    and ``execute_tool`` (in ``tool_execution.py``), which are distinct from this
+    mixin's methods despite the similar names. This module remains importable and
+    emits a ``DeprecationWarning`` from its public methods during the deprecation
+    window; it will be removed from the ``Agent`` MRO after the cycle completes.
    Use ``Agent.chat()`` / ``Agent.achat()`` / ``Agent.execute_tool()`` instead.

-    NOTE: The event-loop bridge previously defined here as
-    ``_run_async_in_sync_context`` **is** live production code (the sync
-    tool-calling path in ``tool_execution.py`` depends on it). It has been
-    relocated to the stable ``async_safety.run_async_in_sync_context`` so that
-    removing this deprecated mixin from the MRO is a true no-op. The method here
-    is now only a thin shim kept for the deprecated public methods above.

 implementation with a thin sync bridge, eliminating code duplication between
 chat()/achat() and execute_tool()/execute_tool_async().

MervinPraisonandClaude Opus 5	323b37bdfc	fix(review): adopt every documented backend protocol, not just get_response Review found the Agent(llm=<object>) fix was incomplete, and it was right. Verified by running it: chat_completion-only backend -> self.llm=<object> custom=False BUG get_response backend -> self.llm="custom/..." custom=True ok llm/protocols.py documents two more backend surfaces besides get_response: LLMProviderProtocol via chat/achat, and UnifiedLLMProtocol via chat_completion/achat_completion. A backend implementing either still fell through to the plain OpenAI branch, where the object became the model identifier and the turn went to the wrong backend -- the same defect the branch was added to fix, for a different protocol. Detection now duck-types across all of them. Five tests, including two controls: a plain object with no backend method is still NOT adopted, and a string llm is unaffected.

MervinPraisonandClaude Opus 5	4b3449f423	chore(parity): waive the two new tool() guardrail parameters, with an expiry CI's signatures gate failed on tool().input_guardrails and tool().output_guardrails: both are new Python parameters with no TypeScript counterpart. These waivers are marked NOT an equivalence. Every other reason in waivers.yaml documents two SDKs reaching the same result by different routes, validated by running both. These record a real gap instead -- nothing in praisonai-ts resolves the same behaviour. They exist only to unblock this PR, because porting is a praisonai-ts change and the two packages do not share a branch. Both carry expires: 2026-12-07. An expired waiver fails the check, so if the TypeScript port is forgotten the gate goes red rather than the gap quietly becoming permanent.

MervinPraisonandClaude Opus 5	0fe844a726	feat: per-tool guardrails Guardrails were agent-wide: _tool_call_guardrails / _tool_result_guardrails are fed only from Agent(guardrails=...) and fire for every tool. Approvals gate calls interactively. Nothing sat between them, so validating one tool's arguments -- rejecting a send_email whose recipient is off-domain -- meant hand-wrapping the function. Adds input and output guardrails scoped to a single tool, declared alongside the approval and trust options a tool already carries. An input guardrail sees the arguments before the tool runs and may block or rewrite them; an output guardrail may block or substitute the result. A blocked call feeds a message back to the model rather than raising at the user. Built on the existing GuardrailResult and GuardrailChain rather than a second guardrail system, so there is one vocabulary for a validation outcome. Ordering relative to the approval gate and the trust fence is chosen for safety and documented at the call site. Co-Authored-By: Claude Opus 5 <[email protected]>	2026-09-07 12:46:23 +01:00
MervinPraisonandClaude Opus 5	b6b0f19cff	chore(parity): regenerate tracker for the new Python exports Merging the three fixes made the tracker stale in a way none of the individual branches showed: each was regenerated before the others existed. Records 6 praisonai-ts gaps (GuardrailRetry plus the five model_harness test-double exports), up from 0. Recorded rather than avoided. Withholding the exports to keep the count at zero would game the measurement instead of reporting it; Python is the source of truth and TypeScript follows in a separate PR, which is exactly the state this tracker exists to make visible.

MervinPraisonandClaude Opus 5	59369664c4	fix: feed guardrail rejections back into the live conversation _apply_guardrail_with_retry already retried on validation failure, but it threw the conversation away: on rejection it built one fresh user message, prompt + "Note: Previous response failed validation due to: ...", and sent that alone. The system prompt, retrieved context, tool results and the rejected answer never reached the retry. Proven against pristine code -- the second request was a single-element message list. So the missing capability was never retry; it was feedback into the live conversation. The retry now appends the rejected assistant turn plus the reason as a user turn and re-calls with the full history, bounded by the max_guardrail_retries that already existed. No competing setting is added. Validators signal rejection the way they already could, by returning (False, reason). GuardrailRetry is added for validators whose check fails several frames down -- a Pydantic parse, a lookup helper -- whose message was previously mangled into "Agent guardrail validation error: ...". The whole-task layer had the same disease: AgentTeam re-ran tasks with the identical prompt, logging the guardrail reason and dropping it. It now fills the Task.validation_feedback slot that already existed, so Process._build_task_context renders it into the re-run. Reuse of existing wiring, not new wiring. Two fixes fell out: the retry passed stream=True regardless of agent config (the sync path logged an ERROR and fell back on every retry), and GuardrailChain buried the rejection under "Guardrail error: ...". Regenerates the parity tracker, which records GuardrailRetry as a new praisonai-ts gap (count 0 -> 1) pending a TypeScript follow-up.

MervinPraisonandClaude Opus 5	f6788b2db7	feat: scriptable test model and a no-network guard Nothing shipped let a user unit-test an agent offline. The repo's own pattern is hand-rolled per test -- LLM.__new__(LLM) followed by assigning twelve private methods -- repeated across three files. ScriptedModel subclasses the real LLM and replaces only the provider-facing methods, so system-prompt assembly, tool-schema serialisation, the tool-execution loop, tool-result messages, streaming and async all run production code. Replies are real litellm ModelResponse objects, parsed by the same path as a live response, so the double cannot drift from reality. It records requests, scripts tool calls, and raises ScriptExhausted rather than hanging or inventing a reply. allow_model_requests(False) blocks every real provider call at the 6 litellm request sites and both OpenAI client properties, and names the offending call site -- which needed a frame walk, since requests are dispatched through an asyncio loop on a worker thread. Fixes a bug found while building this: Agent(llm=<model object>) fell through every branch to the plain OpenAI path, leaving self.llm set to the object itself and _using_custom_llm False, so every turn went to OpenAI under a model name that was really a repr(). Passing your own model did the opposite of what it means. Both new error types derive from BaseException on purpose: the tool loop's broad `except Exception` would otherwise turn "your script is one reply short" into a silent None return.

MervinPraisonandClaude Opus 5	ac9006edc0	fix: never drop an attachment silently _build_multimodal_prompt matched five image extensions and had no else branch, so agent.chat(attachments=["report.pdf"]) appended nothing -- no part, no warning, no error. The model answered from the text prompt alone and the caller could not tell the file was ignored. A mistyped path failed just as quietly, as did pathlib.Path attachments, directories, non-image URLs, non-image data: URIs and video. Routing moves to praisonaiagents/agent/attachments.py with one invariant: an attachment either becomes a model-visible content part or produces a loud signal. The split is on who can act on it, not on severity. Addressing errors raise AttachmentError (a ValueError subclass, so existing handlers still catch): the path does not exist, is a directory, is unreadable, or is not a str/PathLike/dict. These are always caller mistakes and there is no useful degraded answer -- continuing means the model confidently discussing a document it never saw. The message names the path and the cwd, since a relative path resolved from an unexpected directory is the usual cause. Capability limits warn and degrade visibly: the file is readable but the target model cannot ingest that type. A logging.warning names the file, model and remedy, AND a marker part is injected into the prompt so the model knows too and can say it answered without the file. A log line alone would still leave the answer looking complete. PDF, audio and ~45 text/code extensions are now routed per model capability via new supports_pdf_input / supports_audio_input / supports_vision helpers. PDF degrades by local text extraction, labelled as such. Images are unchanged, byte for byte. Co-Authored-By: Claude Opus 5 <[email protected]>	2026-09-07 12:40:28 +01:00
