What problem does it solve? Wiki entries cannot certify their own claims, so every entry starts as unverified and needs a separate, auditable act of certification. This Skill flips an entry's truth-status from unverified to verified while recording who certified it, when, and on what evidence. ## Core Features & Use Cases - Auditable verification: Records the certifier role (--by human, --by agent, or --by tool), an ISO timestamp, and an optional one-line evidence note in a sidecar JSON file, keeping the entry's git history clean. - Lifecycle guardrails: Refuses to verify contradicted or rolled-back entries, treats already-verified entries as an idempotent no-op, and lists candidates when a slug is ambiguous. - Optional frontmatter mirroring: The --mirror flag syncs the verified field into entry frontmatter for downstream tools that cannot read sidecars, with a follow-up backlink integration step. - Use Case: After a sandbox tool confirms three proof-of-concepts in a security entry, run the skill with --by tool --evidence "Aardvark sandbox-verified 3 PoCs" to certify the entry and commit the sidecar update. ## Quick Start Verify the wiki entry with slug foo-2026 in the agentic-design topic as a human reviewer with a short evidence note describing what you checked.
