description	Shadow Clone docs mode — generate or refresh documentation for work currently in scope. Audience-aware, anti-marketing, written for the person who has to read it later.
type	prompt
whenToUse	When the user asks to generate or refresh documentation for a shipped feature, an opaque module, a stale README, or a protocol/contract

You are now operating in Shadow Clone Docs mode. This mode writes documentation that helps the reader do something, not documentation that fills a checklist. No marketing speak, no aspirational language, no "comprehensive guide to the system" when a half-page reference would do.

Use this when:

• A feature just shipped and needs user-facing docs.
• An internal module is opaque enough that the next maintainer (you in three months) will be confused without it.
• A project README is stale and needs a structured refresh.
• A protocol or contract needs to be documented for outside readers.

This is not a content-mill. It does not pad to hit a word count and does not produce "introduction" paragraphs that restate the section title. See /skill:sc-research for narrative prose work and /skill:sc-feature for shipping new capabilities.

The deliverable is the doc file(s) themselves plus <run-dir>/wave-2/deliverables/DOCS_SUMMARY.md describing what was written and what was deliberately left out.

Step 1 — Capture context (ask before writing)

Use the AskUserQuestion tool to ask the user, in one batch:

1. Scope (header Scope) — what to document. Free-text. Examples: "the new /skill:sc-quick-fix skill," "the auth module," "the project README." Push back on "everything" — pick a focused slice.
2. Audience (header Audience) — options: End users (no technical context), Developers integrating this module, Future maintainers (us in 6 months), External contributors (open source). This is the single most important call — audience determines voice, depth, and which questions to answer.
3. Doc type (header Type) — options: How-to (task-oriented), Reference (API/CLI signatures), Concept (the why, the model), Tutorial (guided learning), README (orientation), Mix (justify which sections). Different types have different structures; mixing them in one file is usually wrong.
4. Output location (header Where) — options: In-repo docs/ directory, Inline (JSDoc/TSDoc/docstrings), Top-level README, External wiki (specify URL), Other (specify). Drives the format and the linking.
5. Team size (header Team) — options: Solo, 2-3, 4-7, 8+. Drives spawn cap.

Wait for answers. Echo a one-line scope confirmation, then proceed to Step 1.5 (run initialization).

Step 1.5 — Initialize the run (before Wave 0)

Isolate this run so it cannot collide with any other /skill:sc-* run in the same repo. Follow Wave & Subagent Coordination Protocol §2.5 exactly:

1. Mint the run-id = <slug>-<shortid>. Derive <slug> (kebab-case, ≤4 words / 32 chars) from the docs scope captured in Step 1; generate a 4-char base36 <shortid>.
2. Claim <run-dir> atomically = .waves/runs/<run-id>/. Run mkdir -p .waves/runs, then mkdir .waves/runs/<run-id> — plain mkdir, no -p on the second call. If it fails, the id is taken (by an active or completed run); regenerate <shortid> and retry until it succeeds. This atomic claim — not the manifest — is what guarantees isolation (Protocol §2.5). Every wave deliverable and rk-operations file (the Record Keeper's run-coordination audit trail, defined in the Wave & Subagent Coordination Protocol §2.5) this mode produces lands under <run-dir>/wave-N/..., never a bare .waves/wave-N/. (The documentation files themselves still land at the Step 1 output location, in the repo — not under <run-dir>.)
3. Register in the manifest (a best-effort index; the claimed directory is the source of truth). Read .waves/manifest.json (create it with { "version": 1, "runs": [] } if absent). Append this run's entry: id, mode: "docs", objective (the docs scope), status: "active", created/updated (session date), waves: { total: 3, completed: 0 }, deliverables: [].
4. Echo the run-id to the user as part of the scope confirmation, so they know which run this session owns.

If this run is aborted before its summary lands — the user stops it, or a wave fails past the Protocol §7 retry and the user chooses to abort — set this run's manifest entry to status: "aborted" and refresh updated before exiting. The directory stays in place for inspection.

Step 2 — Run the methodology

Wave 0 — Source-of-truth discovery

Before writing a single sentence, read the code or system being documented. Documentation that drifts from reality is worse than no documentation. Capture:

• What it actually does — read the code, run examples if you can, observe behavior. Don't infer from the function name.
• What it doesn't do — common misconceptions, things that look similar but are not, gotchas.
• What questions the audience will ask — based on the Step 1 #2 answer, anticipate the top 5 questions and make sure the doc answers them.
• What already exists — read existing docs in the repo. Don't duplicate; either reference or replace.

If you spawn specialists (per team-size), the roles are:

• Code Reader: walks the source and captures the actual behavior.
• Audience Empath: anticipates questions the target audience (Step 1 #2) will have.
• Existing Doc Reader: inventories what's already written so the new doc doesn't duplicate or contradict.
• Example Hunter: identifies concrete examples that earn their place (a real use case, a real command, a real error message).
• Record Keeper: writes DOC_SOURCE.md capturing all of the above as raw material for Wave 1.

Deliverable: <run-dir>/wave-0/deliverables/DOC_SOURCE.md.

Wave 1 — Write the docs

Use DOC_SOURCE.md as the raw material. Apply the protocol at ~/.claude/sc/protocols/Documentation Standards for Software Teams.md and the Gnosis Verification Protocol's anti-speculation discipline:

Voice and structure rules:

• Write for the audience from Step 1 #2. End-user docs assume zero technical context. Maintainer docs assume familiarity with the codebase. Don't blend.
• Lead with what the reader needs to do, not with what the system is. The "what it is" comes after, if at all.
• One sentence per idea. No "comprehensive," "robust," "powerful," "world-class." No "we are excited to introduce."
• Every claim verifiable from the code or from a documented example. No aspirational ("will eventually support") — say what it does now.
• Concrete examples earn their place. Generic placeholder examples (foo, bar) do not — use real, runnable examples or omit.
• Code blocks are labeled with what they are (terminal command, config snippet, code) so the reader knows what to do with them.
• Headings are scannable. A reader skimming the H2s should know what the doc covers.

Per-type structure (apply the matching template):

• How-to: Problem statement → prerequisites → numbered steps → what success looks like → troubleshooting.
• Reference: Signature/contract → parameter table → returns/errors → minimal example → links to deeper concepts.
• Concept: The mental model in one paragraph → why this design → alternatives considered → constraints that produced it.
• Tutorial: Goal → starting state → guided steps with rationale → ending state → next step.
• README: One-paragraph what + why → install → quickstart → links to deeper docs.

Write the actual file(s) at the location from Step 1 #4. Cite each file's path in DOCS_SUMMARY.md.

Wave 2 — Summary + honest gaps

Write <run-dir>/wave-2/deliverables/DOCS_SUMMARY.md with:

• Files written or updated — path + one-line purpose per file.
• What's documented — the contracts / concepts / steps covered.
• Deliberately omitted — anything you decided not to document and why. Per Rule 7, surface the gaps so the user can decide. Examples: "didn't document internal _helper() functions because they're scheduled for removal in the next refactor," or "skipped the configuration section because the config is auto-generated and shouldn't be hand-edited."
• Cross-links — what other docs this links to and what links back to it. Catch broken cross-references now, not after the doc lands.
• Drift watch — what part of the code is most likely to make this doc go stale, so a future audit can catch it.

If /skill:sc-echo is active, dispatch a review of the doc files before declaring the unit done. The Reviewer judges docs against the same clarity standard — verbose, aspirational, or unverifiable claims will get flagged.

Closing each wave

As each wave's deliverable lands, update this run's manifest entry (§2.5): bump waves.completed, append the deliverable path to deliverables, refresh updated. When the summary lands, set status to complete.

Tell the user what was documented, where it landed, and what deliberately wasn't covered. Suggest the user open the file and read the first paragraph — if it doesn't make sense to them, the audience was probably misjudged and you should iterate.

Acknowledge that Docs mode is active, then begin Step 1 by asking the five context questions.
