Purpose

An agent that only needs to write or update a blueprint had to load dispatch:design (a whole design conversation) or dispatch:design-review (a whole review), and neither held all the rules. They now live in one skill:

Load `dispatch:blueprint` with the Skill tool.

Design and design-review load it where they used to state the rules. This is an extraction. No rule or outline section was added, dropped or changed in meaning.

Implementation

• New skills/blueprint/SKILL.md with the outline, saving rules, PII, TODO: and [NEEDS CLARIFICATION: ...] markers, run records, the domain-boundary statement, the OpenAPI second document and spec check, Glossary changes, the unnumbered ADR: <title> section, and the read-and-patch rules with the Decision Log entry for review answers.
• skills/design/SKILL.md loads dispatch:blueprint at Start; its "Write the blueprint" section now points to it and keeps the draft-save cadence.
• skills/design-review/SKILL.md loads it at the top; its reading, glossary, ADR and contract steps point to it.
• CONTEXT-FORMAT.md stays in skills/design/; the new skill links ../design/CONTEXT-FORMAT.md, so the three existing links are unchanged.

Calls on the borderline text:

• Kept in design: the three-flag stop on [NEEDS CLARIFICATION: ...], draft saving after each phase, the domain-boundary checks.
• Kept in design-review: the scratchpad blueprint.md copy for sub-agents, offering an ADR, duh lint, "add nothing for dismissed findings". Soft-flag consumers (Pre-work, Phase 4) still spell out the marker.
• Added lines (the only new prose): the one-line summary of what a blueprint is, "Drafts ... can be saved whole. A blueprint saved before your session is changed only by patch" (resolves design's draft saves against review's never-push-whole rule), "When reviewing a saved blueprint" before the Decision Log entry, short glosses for "contract sketch" and "working tree", and a longer description.
• Not changed, per the ticket: skills/design-adr-audit/SKILL.md and skills/design-fit-review/SKILL.md also restate the scratchpad-copy rule.

Verification

make test passes. No evals were run, as asked. A fresh sub-agent loaded anthropic-skills:skill-creator and reviewed the skill without test prompts. I fixed what it found: design-review lacked a load line, the patch-only rule reached design's draft saves, the Decision Log entry was not scoped to review, "soft flags" was undefined, and the description under-triggered. Perspectives not used: a second independent lens on rule-meaning drift.

Suggestions from the review that change a rule, left for you: say which section a run's record goes in; place "We considered X but chose Y because Z" in the Decision Log; Pieces (added by breakdown) is not in the outline.
