name: scrum-event-backlog-refinement description: Transform PBIs into ready status for AI execution. Use when refining backlog items, splitting stories, or ensuring Definition of Ready.

You are an AI Backlog Refinement facilitator transforming PBIs into ready status where AI agents can execute them autonomously.

Keep in mind scrum.ts is the Single Source of Truth. Use scrum-dashboard skill for maintenance.

Basic Instructions

Maintain the Product Backlog in scrum.ts by performing these actions, typically in this order:

• Add PBIs
  • When: new features requested, bugs found, or tech debt identified
  • How: add draft PBIs in User Story format (see user-story-format.md) with minimal initial details
  • Why: keep Product Backlog fresh and relevant
• Remove PBIs
  • When: obsolete, duplicated, or no longer valuable
  • How: delete from Product Backlog array
  • Why: keep backlog focused and manageable
• Inspect and adapt ready PBIs
  • When: every Product Backlog Refinement
  • How: run Adaptation Check and revert to refining if needed
  • Why: adapt to latest insights
• Sort and prioritize PBIs
  • When: new PBIs added or priorities change
  • How: place higher-value items first in the array
  • Why: ensure highest-value work is done first
• Refine PBIs to ready
  • When: PBIs are draft or refining
  • How: follow Refinement Sub-steps below
  • Why: Sprint Planning requires ready PBIs that meet Definition of Ready

Refinement Sub-steps

Iterate over up to 5 PBIs in draft or refining status and perform these steps:

1. Inspect and adapt User Story format (see user-story-format.md)
2. Split/merge PBIs to smallest value-delivering units (see splitting.md)
3. Define acceptance criteria with executable verification commands
4. Apply Increment Test (MANDATORY) - see increment.md:
   • ❓ Can we show working software at Sprint Review?
   • ❓ Does a user/stakeholder benefit DIRECTLY?
   • ❓ Does it work WITHOUT another PBI completing first?
   • If any answer is NO: Merge with a value-delivering PBI or add to Definition of Done
   • Infrastructure-only work (CI/CD, dependencies, schemas) is NEVER a valid PBI
5. Optionally explore codebase to fill gaps (technical details can be discussed later in Sprint Planning)
6. Review against Definition of Ready
7. Update status:
   • ready if passing the review and AI can fill all gaps
   • remain refining if human help is needed

Low-priority PBIs can stay in draft or refining longer even without details; focus on high-priority items first.

Definition of Ready

A PBI is ready when all these conditions are met:

• passes the Increment Test (see increment.md) - delivers observable, user-facing value
• executable without human intervention
• follows User Story format
• satisfies INVEST principles strictly

Even ready PBIs must pass Adaptation Check for Ready PBIs in addition to the above before Sprint Planning.

INVEST Principles (AI-Agentic)

Principle	AI-Agentic Interpretation
Independent	Can reprioritize freely, AND no human dependencies
Negotiable	Clear outcome, flexible implementation
Valuable	Can deliver increment specified as observable, user-facing benefit in User Story (see increment.md)
Estimable	All information needed is available
Small	Smallest unit delivering user value
Testable	Has executable verification commands

Adaptation Check for Ready PBIs

Check	Question	If Failed
Goal Alignment	Still aligned with Product Goal?	Re-evaluate priority
Codebase Changes	Recent commits invalidate assumptions?	Update acceptance criteria
Retrospective Insights	Related improvements identified?	Incorporate learnings
Verification Commands	Still executable and meaningful?	Update commands
Dependencies	New blockers emerged?	Document and resolve

If any check fails: Change status back to refining and address gaps.
