What problem does it solve? Long agent walks lose decisions, accepted limitations, and process lessons in ephemeral scratch notes; this Skill enforces categorized, machine-validated durable record-keeping so the trail stays reconstructable. ## Core Features & Use Cases - Category model: Routes each step's output into flight-log, tech-debt, or process-feedback records, each with a defined contract, .ledger home, and trigger. - Three-gate promotion: Promotes artifacts from scratch to ledger or repo/docs via structural readiness (Nickel contract validation), a zero-context sensibility read, and role-based authorization. - Use Case: When an agent accepts a known limitation instead of fixing it, it writes a tech-debt YAML entry with a falsifiable claim and signpost, validates it with nickel export --apply-contract, and commits it to .ledger/tech-debt/ instead of burying it in prose. ## Quick Start Ask the agent to record the limitation you just accepted as a validated tech-debt entry in the ledger.
