Chained Multi-Skill Pipeline & Stage Transition Polish

# Multi-Skill Chained Workflow Optimization Protocol ## Objective Review a multi-agent workflow composed of multiple chained skills. Optimize the inter-stage data schemas, execution order, failure containment, and verification gates. --- ## Key Optimization Axes: 1. **Schema Standardization:** Ensure the output of Stage N matches the exact JSON/Markdown structure required by Stage N+1. 2. **Context Pruning:** Filter out intermediate scratchpad noise so downstream agents only receive high-signal inputs. 3. **Quality Gates & Checkpoints:** Add deterministic verification steps between stages to catch errors early. 4. **Idempotency & Resumability:** Design stages so failed workflows can resume from the last successful checkpoint without repeating expensive calls.
