v0.5.0

[0.5.0] - 2026-03-04

Added

• Cascading cancellation: update(status="cancelled", cascade=true) cancels all non-terminal descendants
• Parent auto-rollup: Parent tasks auto-complete when all children reach terminal states (enabled by default)
• bulk_update tool: Batch status transitions across multiple tasks in a single call
• files parameter on claim: Auto-mark files being worked on at claim time
• prompts parameter on update: Coordinator prompt filtering (all/none/caller) to control which prompts are returned
• File contention detection: claim warns when marked files overlap with other active tasks
• Source attribution on prompts: get_prompts and transition prompts now return {"text": "...", "source": "workflow:enter~working"} with provenance
• Prompt delivery for pre-assigned tasks: Workers receive full transition prompts when claiming coordinator-assigned tasks
• Overlay resource discovery: docs://overlays/list and docs://overlays/{name} resources for exploring available overlays
• Workflow/overlay metadata in feedback: give_feedback records workflow name and active overlays from worker registration
• Uptree project directory discovery: Agents running in subdirectories or git worktrees find the parent project automatically
• Git worktree overlay advisories: 6 new advisories (worktree-setup, patch-generate, patch-apply, patch-conflict, worktree-rebase, worktree-cleanup, layered-worktree)
• Commit gate (gate/commit) in git overlay
• 28 new integration tests covering prompt delivery, file contention, and update prompts parameter

Changed

• All timestamp display converted to ISO 8601 (RFC 3339) format
• Overlay prompts rewritten for actionability (git, git-worktree, reasoning overlays)
• Git overlay enter/exit prompts now include mark_file and thinking() guidance
• Unsatisfied dependency blockers filtered from list_tasks display
• Worker role prompts in all workflow topologies now include "review prompts after claiming" guidance

Fixed

• Multi-claim accounting: enforce max_claims limits correctly, fix counting across timed states
• register_worker test calls updated for max_claims parameter
