Skill Fusion

Q: How do I know the Skill Fusion output is good?

The skill verifies itself against its own quality checks: The dominant parent was chosen by audience analysis, stated in one sentence — not by which skill came first; Every parent section is dispositioned (keep/merge/drop) with a reason — no silent omissions; The fused structure is shorter than the sum of parents — fusion compresses or it's stapling; At least one ⚗️ hybrid-only quality check exists — if none, the task probably needed one parent, and the output should say so.

🔵 Stable🕐 updated 2026-07-08 🔷 SkillSpec L3 pm-advanced

Fuse two skills from this library into one hybrid brief for a task that sits between them — the meta-skill. Use when a task straddles two skills (a PRD that's also a pitch; a postmortem that must double as a board update) and running them separately would produce two documents where one is needed. Produces the fused operating brief: combined structure, merged quality bar, precedence rules for where the parents disagree, and the fused output itself if input was provided.

What to give it

▸The two parent skills — by name if known; otherwise describe the task and identify the two best parents first (say which and why).

▸The task itself — what's being produced, for whom. The audience decides which parent leads.

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓The dominant parent was chosen by audience analysis, stated in one sentence — not by which skill came first

✓Every parent section is dispositioned (keep/merge/drop) with a reason — no silent omissions

✓The fused structure is shorter than the sum of parents — fusion compresses or it's stapling

✓At least one ⚗️ hybrid-only quality check exists — if none, the task probably needed one parent, and the output should say so

✓The staple test ran: no section sequence alternates parent voices without a merge

⚠️ What it refuses to do

Do not fuse more than two skills — three-parent hybrids are committees; run fusion twice if truly needed

Do not fuse when one parent covers 90% — the honest output is "use X, borrow one section from Y", and it should say exactly that

Do not average conflicting rules — precedence means one wins per conflict, visibly

Do not inherit boilerplate from both parents (two intros, two summaries) — the classic staple smell

Do not let the fusion drop both parents' verification sections in the compression — the quality bar merges; it never thins
