Beat Writer

Channel-agnostic, beats-first writer for uncommitted drafts. Owns extraction + shaping; delegates prose to /authors-voice (operator's default anchor — personal voice). Output is a plain OpenWriter doc that can stay generic OR get refactored later into a specific channel via a channel-master writer.

4-layer model:

1. EXTRACT — pull beats out of the operator. Same query-first, 5-pass discipline used by /book-writer. Channel-agnostic CATEGORY tags (CLAIM / REFRAME / MECHANISM / EVIDENCE / STORY / APHORISM / PIVOT / OBJECTION). docs/extraction.md
2. SHAPE — order beats by reader flow, lock as commitments (no content prescription). No channel template — just a sequenced beats list. docs/beat-method.md
3. VOICE — /authors-voice Apply Protocol with the operator's DEFAULT anchor (personal voice). Same machinery as every other writer; no anchor swap. The piece sounds like the operator.
4. POLISH — /polish to 90/100, then /anti-ai, then a naive-reader pass (/congruence if installed, otherwise inline). Delegated, not duplicated.

Firm rules

1. Single entry point. Invoked as /beat-writer only. No subcommands, no flag-syntax args. Internal dispatch from context.
2. EXTRACT before WRITE. Same query-first discipline as /book-writer. AI never invents beats; the operator's head is the source.
3. Beats are commitments, not content. Each beat names the OUTCOME (what the reader registers / what shift lands). The voice layer brings the words.
4. No channel template. This skill deliberately does NOT impose a page structure, thread shape, post format, or chapter container. The draft is shapeless-by-design (just a sequenced beat list) so any channel-master can later re-shape it.
5. Voice = /authors-voice Apply Protocol with operator's DEFAULT anchor. Same machine, default fuel. The piece sounds like the operator. Editor never writes prose directly; every pour is a minion dispatch. Same Rule 1 as /authors-voice.
6. OpenWriter is the writing surface. One container per draft; Beats doc + Draft doc inside (same convention as /blog-writer). Workspace: [Project] Drafts (or reuse the operator's existing writing workspace if present).
7. Refactor is optional. When a draft's destination becomes obvious, hand off to the appropriate channel-master (/blog-writer, /x-writer, /newsletter-writer, /book-writer). Refactor doesn't move the draft; the channel-master reads the Beats + Draft docs and re-shapes into its own container. See docs/refactor.md.
8. Polish is delegated. /polish → /anti-ai → naive-reader pass (/congruence if installed, otherwise read as a first-time reader and fix inline). Do not duplicate their logic.

Companion skills

• /authors-voice — REQUIRED. Every prose pour delegates to its Apply Protocol with operator's default anchor.
• /polish — REQUIRED for the 90/100 push.
• /anti-ai — final fingerprint scrub after polish.
• /congruence — naive-reader pass for jargon / broken flow (optional; if not installed, do this pass inline).
• openwriter — REQUIRED. Beats + Draft docs live here.
• /blog-writer / /x-writer / /newsletter-writer / /book-writer — refactor targets when the draft's destination becomes clear.

What this skill does NOT cover

• Channel-specific shape — page templates, thread structure, blog post layout, email scaffolds, chapter containers. Those belong to channel-masters.
• Channel-specific constraints — character budgets per slot. Use /x-writer for tweet/article budgets.
• Voice machinery — /authors-voice owns Apply Protocol, NEVER-rule patching, fingerprint audit, blinder audit.
• Personal-voice setup — /authors-voice owns anchor setup, NEVER rules, fingerprints, corpus analysis.
• Publishing — channel-master skills own publish mechanics.

When to skip this skill

• Known channel from the start — use the channel-master directly (/blog-writer, /x-writer, etc.)
• Single-paragraph or one-liner — /authors-voice directly is faster
• Pure ideation (no draft target) — talk it out, don't formalize it
• Polish-only on existing prose — /polish directly
