What problem does it solve? Subagent and worker reports are often verbose, burying the verdict, evidence, and required action under chronology and filler. This Skill enforces a compact communication contract so receiving agents can decide, verify, continue, or stop without decoding long prose. ## Core Features & Use Cases - Structured report envelope: Standard fields (STATE, RESULT, EVIDENCE, CHANGED, GAPS, NEXT) for worker reports, plus FINDING/IMPACT/FIX variants for review findings and a minimal two-line form for live status updates. - Compression rules: Lead with the result, name exact artifacts, merge repeated findings by root cause, and send only one recommendation, with no greetings or recaps. - Fidelity floor: Brevity never removes authority limits, stop conditions, destructive-action gates, exact numbers, uncertainty, or failed checks. - Use Case: When dispatching a subagent to investigate a bug, include this return contract in the worker brief so the report comes back as a terse, decision-ready envelope instead of a narrative log. ## Quick Start Ask the agent to report its completed task using the agent-output envelope with STATE, RESULT, EVIDENCE, and NEXT fields.
