What problem does it solve? Dispatched Kanban workers often fail silently by producing bad handoffs, claiming phantom cards, blocking with vague reasons, or repeating the mistakes of prior failed runs. This Skill provides the deeper operational detail beyond the auto-injected lifecycle guidance so workers complete, block, and hand off tasks correctly. ## Core Features & Use Cases - Structured handoff patterns: Concrete examples of kanban_complete summaries and metadata shapes for coding, research, and review tasks, including review-required blocking flows. - Workspace and tenant handling: Rules for scratch, shared directory, and git worktree workspaces, plus tenant-prefixed memory isolation. - Retry and failure diagnostics: How to interpret prior run outcomes (timed_out, crashed, spawn_failed, reclaimed) and avoid repeating failed paths. - Codex lane integration: Optional isolated implementation lane using Codex CLI in a git worktree, with reconciliation checklists and metadata schema. - Use Case: A worker dispatched to fix a rate limiter completes with structured metadata (changed files, test counts, decisions), claims only verified created cards, and blocks with a specific review-required reason so a human can approve the merge. ## Quick Start Load the kanban-worker skill and follow its handoff and blocking patterns to complete your dispatched Kanban task with structured metadata.
