+# Voice & tone
+
+This is the writing-style guide for Spacedock's public documentation. It is grounded in two real voice signals, not invented:
+
+- **The root `README.md`** — Spacedock's actual public voice: direct, anti-hype, claim-first ("Spacedock is a multi-agent orchestrator where nothing ships without a decision"), concrete over abstract, second person addressed to the reader.
+- **The `comm-officer` mod** (`docs/dev/_mods/comm-officer.md`) — the project's prose discipline. It applies the `elements-of-style:writing-clearly-and-concisely` skill (Strunk) and is **light-touch by default**: "Preserve the caller's voice, rhythm, and technical vocabulary. Cut empty words, tighten sentences, fix clear grammar errors." Critically, it **defers to a project voice guide when one exists**. This page is that guide — so the comm-officer and any doc-writer apply it.
+
+## Voice
+
+- **Precise, honest, technical.** State what is true and what a thing does. Spacedock's own pitch leads with the claim, not the adjective.
+- **No marketing or hype adjectives.** Avoid "powerful", "seamless", "revolutionary", "effortless", "blazing-fast", "game-changing". If a sentence still carries its meaning with the adjective removed, remove it. The product ethos — evidence over assertion — is the writing ethos.
+- **Concrete over abstract.** Name the command, the file, the outcome. Prefer "`spacedock status --next` lists the items ready to dispatch" over "Spacedock surfaces actionable work."
+- **Claim-first, then support.** Lead a section with the load-bearing sentence; follow with the detail. Mirrors the README's "what's different" bullets (bold claim, then the mechanism).
+
+## Tone and register per audience
+
+- **New-user pages (Get started): welcoming and encouraging, still precise.** Assume no prior Spacedock knowledge; define a term on first use; show the command and the output to expect. Confidence-building, never breezy.
+- **Operator pages (Concepts, Running workflows): direct and operational.** The reader is doing the work; tell them the steps and the decision points plainly.
+- **Contributor pages (Contributing, Reference): exact and unembellished.** Precision outranks warmth. Name the contract, the test, the failure mode.
+- **Person and tense.** Second person ("you run", "you approve") and present tense for how-to and instructions — the README's register. Imperative for steps ("Run `spacedock doctor`."). Describe the system in the present tense ("the first officer dispatches an ensign"), not the future.
+
+## Canonical terminology and capitalization
+
+Pinned from how the README and skills actually use these forms — not an imposed guess. Use them consistently.
+
+| Term | Form | Notes (grounded in real usage) |
+|------|------|--------------------------------|
+| Spacedock | `Spacedock` | The product. Always capitalized. `spacedock` (lowercase, code font) only as the literal command/binary. |
+| Captain | `Captain` (role) / `the captain` (prose) | README roles table capitalizes the role name; running prose uses lowercase "the captain" (skills use `{captain}`). The human operator. |
+| First Officer | `First Officer` (role) / `the first officer` (prose) | Same pattern: Title Case in the roles table / when naming the role; lowercase in running prose ("the first officer reads the README"). The orchestrator agent. |
+| Ensign | `Ensign` (role) / `the ensign`, `ensigns` (prose) | Same pattern. The worker agent that moves one item through one stage. |
+| workflow | `workflow` | Common noun, lowercase. A directory of markdown entities + a README. |
+| entity | `entity` | Common noun, lowercase. One work item (a markdown file or folder). The README also says "work item" — prefer "entity" in docs, gloss it as "work item" on first use for new users. |
+| stage | `stage` | Common noun, lowercase. backlog → ideation → implementation → validation → done. |
+| gate | `gate` | Common noun, lowercase. The decision point at the end of a stage. |
+| sprint | `sprint` | Common noun, lowercase. A grouped set of entities driven to a deliverable. |
+| worktree, mod, safehouse | lowercase | Common nouns. `safehouse` is also the sandbox profile filename `.safehouse`. |
+
+Rule of thumb: capitalize a **role** when you name it as a role (the roles table, a definition); use lowercase for the same word in ordinary running prose; never capitalize the common-noun primitives (workflow, entity, stage, gate, sprint).
+
+## Formatting conventions
+
+- **Commands and code.** Inline code font for commands, flags, filenames, and identifiers: `spacedock claude`, `--strict`, `mkdocs.yml`. Multi-line commands and config in fenced code blocks with a language tag (` ```bash `, ` ```yaml `).
+- **Show expected output.** For a command a reader runs, name the result, as `install.md` does ("Prints the installed version, e.g. `spacedock 0.20.0`").
+- **Headings.** Sentence case ("Get started", "Your first workflow"), not Title Case. One `#` h1 per page (the page title); section headings start at `##`.
+- **Links.** Descriptive link text, never "click here" / "this link". Internal links are relative so `mkdocs build --strict` can resolve them.
+- **Lists and emphasis.** Bullets for parallel items; bold for the load-bearing claim of a bullet (the README pattern). Use emphasis sparingly — if everything is bold, nothing is.
+
+## How this guide is applied
+
+The `comm-officer` mod loads a project voice guide on first use and defers to it over plain Strunk. Once this page ships, it is that guide: doc contributions and comm-officer polish follow these rules. When this guide is silent on a question, fall back to Strunk via `elements-of-style:writing-clearly-and-concisely`.

+        Documentation for Spacedock, a multi-agent orchestrator where nothing
+        ships without a decision. It lives within your existing coding harness
+        (Claude Code, Codex, or Pi), breaks work into stages, and surfaces an
+        evidenced decision at each gate.
