+description: Drive authoring of a human-audience design document — a narrative that explains a settled design for a person to understand, not for an agent to execute — one section at a time with user review between chunks, delegating the writing to the mid-tier-technical-writer agent. Also drives standalone editing passes on such a doc (clarify, simplify, restructure, re-term). Use only when the user explicitly asks to write, draft, or edit a human-readable design doc, or to turn a brainstorm, decision log, or design notes into one. This is an opt-in, manually invoked workflow — do not trigger it automatically for general writing, editing, or documentation tasks. Not for planning or agent-targeted RFCs, execution plans, or reference documentation (domain, architecture, component, business-process); those have their own paths.

+# Authoring Human-Readable Design Docs
+
+Drive the creation of a design document written for a person to understand a
+design — the kind of narrative you hand a colleague so they grasp how something
+works and why, not a spec an agent executes. The design is already settled; this
+workflow turns it into readable prose and keeps it readable over later editing
+passes.
+
+Work incrementally. Author one section at a time and let the user review each
+chunk before moving on. One-shot drafts of a whole doc cost more, bury mistakes,
+and review worse — small chunks keep the user in control and catch drift early.
+
+## The agent that does the writing
+
+The `mid-tier-technical-writer` agent writes and edits the prose. The voice,
+tone, and wording rules live in that agent, not here — this skill orchestrates
+and defers every writing decision to it. Do not write the document prose
+yourself in the coordinating session, and do not restate the agent's writing
+rules here; that only creates a second, drifting copy.
+
+Give the agent the source material and the target section, and relay its output
+back to the user concisely.
+
+## The one boundary: wording versus design
+
+Each round of user feedback is either about the writing or about the design.
+Classify it before you act:
+
+- **Wording, structure, or clarity** — rephrasing, reordering, splitting or
+  merging sections, simplifying a dense passage, fixing a term. This is in
+  scope. Route it to the writer agent.
+- **The design itself** — "actually, let's change how X works," a new
+  constraint, a reversed decision, a different approach. This is out of scope.
+
+When feedback changes the design, stop. Do not hand it to the writer agent and
+do not absorb it into the prose. The writer agent must not invent or alter
+design conclusions; if it did, an unreviewed design change would end up buried
+in a document instead of being decided deliberately. Tell the user plainly that
+this is a design change, and suggest they take it back to the drawing board in a
+separate design session, then return to authoring once the design is settled
+again.
+
+## Workflow
+
+1. **Setup** — Confirm the section structure (take the user's, or propose one
+   and get agreement) and the output file. Write to a new file and leave any
+   original source untouched, so the source stays available for reference.
+   Identify the source material the doc is built from.
+2. **Author section by section** — Send one (sub)section at a time to the writer
+   agent, relay the result, and let the user review before the next. Defer terms
+   or links that point at sections not yet written; add the backlinks once the
+   target section exists, so the draft never references something that isn't
+   there.
+3. **Editing passes** — For polish on an existing doc, use the same agent for
+   standalone passes: clarify wording, simplify dense or math-heavy passages,
+   restructure, fix terminology, remove repetition.
+4. **Wrap-up** — Check that cross-references and anchors resolve. If a pass
+   surfaced a fix that also belongs in the source design material, note it for
+   the user rather than silently changing only the doc.
+
+## Coordinator behaviors
+
+- When the user is confused by a passage, explain the concept in plain terms
+  first, then let that explanation drive the rewrite. Often the plain
+  explanation you just gave is the model for the fixed prose.
+- Prefer incremental progress over large one-shot sections — cheaper and easier
+  to review.
+- User decisions override. Do not silently re-decide something the user already
+  settled.
