From 8c90d21c7ba9e002516eaf69a535a59d63fbca0c Mon Sep 17 00:00:00 2001 From: Aditi Kumari Date: Mon, 22 Jun 2026 23:09:02 +0530 Subject: [PATCH 01/12] feat(governance): add Microsoft Agent Framework governance adapter Appends a ChatMiddleware (BEFORE/AFTER_MODEL) and FunctionMiddleware (TOOL_CALL/AFTER_TOOL) to agent.middleware; walks WorkflowAgent executors for multi-agent apps. Self-registers via the uipath.governance.adapters entry point; unit-tested and verified firing through the framework's real execution path. BEFORE/AFTER_AGENT remain owned by the uipath-runtime wrapper.

charset=UTF-8 Content-Transfer-Encoding: 8bit Review findings (Viswa) for PR #361: - AFTER_MODEL / AFTER_TOOL now run inside a try/finally around call_next, so they still fire (audit + rules observe the turn) when the model or tool call raises. GovernanceBlockException from before_* still aborts before call_next; the underlying error still propagates after the finally. - Streaming AFTER_MODEL: on a streaming ChatContext, context.result is a ResponseStream after call_next (reading it yielded empty text). We now register a stream_result_hook so AFTER_MODEL runs on the finalized ChatResponse the framework assembles once the stream is consumed. - Drop the per-callbacks uuid trace_id (identical for every call); trace correlation is owned by the layer below, matching LangChain. Requires uipath-core >= 0.5.20 (removed trace_id from EvaluatorProtocol) — bumped. - Count llm/tool calls only after governance passes: a DENY raised before the bump, inflating the counter on blocked calls. - Cap _stringify output so an oversized tool result / message can't hand a multi-megabyte string to the evaluator. - Trailing newline (W292). Note: agents are not cached by the factory (each runtime gets a fresh instance to avoid concurrent-Workflow reuse), so the cached-agent re-attach concern does not apply here — the idempotency guard is only a double-install safety net. The PR description's entry-point claim is stale (factory-evaluator uses no governance entry-point) and will be corrected. Tests: added finally-on-error (model + tool), streaming result-hook, and no-inflation-on-block coverage.

charset=UTF-8 Content-Transfer-Encoding: 8bit Follow-up to the #361 review pass — the earlier commit covered streaming (stream_result_hook), try/finally, trace_id, counters, and the _stringify cap; these are the rest: - middleware.py:113 (walk gap — page-2 theme + minor 8) — _iter_agents now RECURSES through nested WorkflowAgents (workflow-of-workflows). Before it stopped one level down, so a nested workflow's inner agents ran ungoverned. Converted to an explicit stack walk with a _MAX_GRAPH_NODES cap that logs when it trips (was a silent inline `len(seen) < 1000`). - middleware.py:326 (_coerce_args) — log a warning when model_dump() fails instead of silently dropping the tool args from governance visibility. - middleware.py:135 (nit) — inverted the empty-targets check to a guard clause. Tests: nested-workflow recursion + cycle-safety (self-referential executor); streaming + AFTER_MODEL-on-error were added in the earlier pass. 141 pass. Acknowledged, unchanged: latest-message-only scan (same documented tradeoff as #899); cached-agent re-attach does not apply — this factory does not cache agents (fresh per runtime) and trace_id is no longer held.
