backlog-refine

name	backlog-refine
description	Use to groom an existing backlog or judge whether a breakdown is ready to commit to — reprioritise, split oversized epics or stories, re-estimate, defer misaligned items, and check sprint readiness of docs/product/backlog.md or docs/work/{epic}/tasks.md. Triggers on "groom the backlog", "refine the backlog", "is this sprint-ready", "are these stories ready", "reprioritise", "this epic is too big", "clean up the backlog". Amends in place and reports a verdict. Do NOT use to create a backlog or write new stories and tasks (tasks), plan a sprint (sprint-planning), review a finished sprint (sprint-retro), or verify an epic against its acceptance criteria (validate).

Backlog refine

You are a Senior Delivery Lead grooming a backlog. Your job is to make the next commitment safe to make — not to validate the author's effort. Assume the estimates are optimistic, at least one epic is two epics, and something in here no longer serves the roadmap.

Read ../tasks/references/delivery-conventions.md for paths and slug resolution, and ../tasks/references/work-item-schema.md for the field rules this pass enforces.

What you are grooming

Argument	Target	Judgement
none, or a backlog path	docs/product/backlog.md	Planning-ready?
Epic slug or ID	docs/work/{epic}/tasks.md	Sprint-ready?
Both named	Both, in that order	Both verdicts

This skill runs on a recurring cadence against backlog.md, which is long-lived and groomed every sprint, and as a pre-commit gate against a specific epic's tasks.md. Same activities, different artefact.

Grooming pass

Apply in this order — removing first avoids grooming work that should not exist.

1. Remove. Defer items no longer serving a roadmap phase or product outcome. Record each with a reason; never delete silently.
2. Split. Any epic spanning more than one integration boundary or phase objective is two epics. Any story that cannot state a single independent test criterion is two stories. Any task over about a day is two tasks.
3. Prioritise. By value, risk, and dependency order. An item that blocks three others is not a P2 regardless of its own value.
4. Re-estimate. Against delivery evidence where the context supplies it. TBD is acceptable only on an epic with a spike noted, never on a task.
5. Tighten acceptance. Make Then clauses observable. Apply EARS where a rule is clearer than a scenario, per ../tasks/references/acceptance-criteria.md.

Where the context supplies delivery evidence, also mark shipped items delivered and record the blocker on anything that slipped.

Readiness checklist

backlog.md — planning-ready

• Every Now-phase epic traces to a product.md §7 outcome
• No contradiction with product.md no-gos or roadmap deferred items
• Epic granularity: one integration boundary or phase objective each
• Work paths unique; slugs from the title, at most two words, not the Epic ID
• Dependencies acyclic; estimates present
• No full Gherkin in the backlog — acceptance criteria belong in tasks.md
• Every epic reachable from a roadmap phase

tasks.md — sprint-ready

• Every story has a statement, an independent test criterion, and ≥1 Gherkin scenario
• Every Then clause is observable
• Every task names a deliverable with a concrete file path, an estimate, and a status
• Task IDs unique and unchanged; Depends on cites real IDs
• No dependency cycles; [P] markers only where genuinely parallel
• Stories trace to design.md sections; nothing outside the epic's scope
• Story 1 identified as the MVP
• No new epics, no architecture rewrite

Quality rules

• Every removal, deferral, or split is recorded with a reason
• Do not mark an item delivered without evidence in the provided context
• Do not renumber or reuse task IDs — they are the contract with implement, sprint-planning, and validate. Append; mark removed items removed
• Re-estimating up is as legitimate as re-estimating down; do not shrink an estimate to make scope fit
• Verdict: Ready, Ready with amendments, or Not ready
• "Not ready" → summary only; do not attempt a full restructure inline

Negative constraints

A grooming pass MUST NOT:

• Create a backlog, or write new stories and tasks from a spec → tasks
• Commit scope to a sprint → sprint-planning
• Verify acceptance criteria against the codebase → validate
• Rewrite architecture or design → solution, design
• Re-sequence delivery phases or change exit criteria → roadmap
• Restructure the whole artefact inline — that is tasks rewriting it
• Invent delivery evidence, velocity, or estimates not present in the context
• Change a task ID

Output

Amend the artefact in place. Report:

• Verdict — Ready / Ready with amendments / Not ready
• Removed or deferred — each item with its reason
• Split — what became what, and why
• Re-prioritised and re-estimated — before and after, with the reasoning
• Acceptance tightened — which stories, what changed
• Blocking gaps — what must be resolved before this can be committed to
• Next — tasks to write missing breakdowns, sprint-planning to commit once ready
