From f8e8d25b5f8b11718350d13b38721979404ada1a Mon Sep 17 00:00:00 2001 From: root Date: Mon, 20 Apr 2026 15:28:30 -0500 Subject: [PATCH] Unblock complex scenarios: JSON tolerance + optional question + mistral exec MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit parseAction now strips stray `)` before `}` and trailing commas — qwen2.5 emits those regularly on tool_call outputs; soft-fix beats retry-loops. hybrid_search no longer hard-requires `question`; defaults to "qualified available workers" when the model drops it (mistral's most common failure mode on complex events). Kept original TOOL_CATALOG shape (args examples only, not full action envelopes). The verbose few-shot version from the prior iteration confused mistral into wrapping propose_done as tool_call. Scenario V7 result: expansion (5 Forklift Ops) and emergency (4 Loaders) — previously-failing complex events — now seal reliably. Pool sizes: 687 and 380 from 500K corpus. Patterns endpoint produces real operator-actionable signals: expansion: "recurring certifications: Forklift (40%), OSHA-10 (40%) · recurring skills: mill (40%) · archetype mostly: leader · reliability median 0.83" Baseline + recurring are now flaky (inverted trade-off, pure model-reliability variance). --- tests/multi-agent/agent.ts | 33 ++++++++++++++++++++++----------- tests/multi-agent/scenario.ts | 17 ++++++++++++++--- 2 files changed, 36 insertions(+), 14 deletions(-) diff --git a/tests/multi-agent/agent.ts b/tests/multi-agent/agent.ts index 167e9c2..b52344b 100644 --- a/tests/multi-agent/agent.ts +++ b/tests/multi-agent/agent.ts @@ -121,8 +121,8 @@ Available tools (each takes a JSON "args" object): → Canonical production tool for fill tasks.
