Extends Capability Evolver with verification, rollback, and promotion gating. Use when an agent logs a learning, proposes a self-improvement, or wants to promote a learning to permanent memory. Before promotion, define a deterministic spec, verify actual output via SettlementWitness, then PASS → promote with receipt_id, FAIL → rollback and log counter-evidence, INDETERMINATE → hold for review." Verification is performed via an external SettlementWitness service. This skill defines the verification requirement and workflow but does not embed API clients or credentials; integration is handled by the runtime or connected verification layer.

From the source SKILL.md

This verified version ensures every promoted learning is externally validated by SettlementWitness, preventing incorrect patterns from becoming permanent agent behavior. Log learnings and errors for continuous improvement, but do not allow permanent self-modification unless the improvement is verified. This skill adds a verification gate before promotion to project memory, attaches SettlementWitness receipts to promoted learnings, and requires rollback when a promoted learning later fails verification.

What this skill does

Verified Capability Evolver is a community-contributed Claude Code skill in the forensics sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/verified-capability-evolver/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when an agent logs a learning, proposes a self-improvement, or wants to promote a learning to permanent memory.
