Nick Vigilante 25a6bf56c9 docs: state what the style guide tooling actually checks (#29298)
## Summary

The style guide documents 77 rules. Tooling checks 8 of them, one of
which doesn't run on published pages, and Vale runs advisory so no
finding fails a build. Nothing said so, and several annotations said the
opposite.

This corrects the false claims and states the coverage where authors and
agents actually read.

### The false claims

Nine annotations read as active enforcement with no `(planned)` marker:

- `Google.Gender`, `Google.GenderBias`, `Google.Headings`,
`Google.HeadingPunctuation`, `Google.OxfordComma`, `Google.Quotes`,
`Google.Exclamation`, `Google.Ranges`. The repo-root `.vale.ini` sets
`BasedOnStyles = Coder`, and the doctrine in `docs/.style/README.md`
deliberately excludes third-party rules.
- `Coder.FirstPersonSingular` and `Coder.FirstPersonPlural`. No YAML
exists for either in the rule package.

All are now marked planned, matching the 17 annotations that already
were.

### What changed

| File | Change |
|---|---|
| `docs/.style/style-guide/README.md` | New "What the tooling checks,
and what it doesn't" section: per-rule table with tool, severity, and
scope, per-section coverage counts, and the enumeration and
classification rules that reproduce them |
| `docs/.style/style-guide/capitalization-and-punctuation.md`,
`voice-and-tone.md`, `accessibility-and-inclusion.md` | Mark the 9 false
enforcement claims planned |
| `docs/.style/style-guide/audience-and-scope.md` | Give each rule its
own enforcement footer, so the page's 6 rules stop counting as 1 |
| `docs/.style/style-guide/word-choice.md` | Say that `Coder.BrandNames`
covers `HashiCorp` casing only, and give the What's next? sub-rule its
own footer |
| `docs/about/contributing/documentation.md` | Drop "to enforce prose
style"; state that Vale covers a subset and a clean run isn't
conformance |
| `AGENTS.md`, `.claude/docs/DOCS_STYLE_GUIDE.md`,
`.claude/skills/write-docs/SKILL.md` | Same statement for agents; split
the skill checklist item so applying the guide and passing linters are
separate gates |

## Why

An agent (me) wrote a new install page, ran `make lint/prose` and
markdownlint clean, and shipped a draft that violated
one-sentence-per-line, the "refer to" rule, `sh` fence tags, H3 tab
headings, and the Learn more heading. None of those are enforced. The
single checklist item that bundled "style guide applied with it open"
with "Vale passes" made the substitution easy to miss.

<details>
<summary>Verification and method</summary>

### Empirical probe

A scratch file violating 12 documented rules (gerund heading, trailing
heading punctuation, first person singular and plural, `Click`,
`Github`, `Hashicorp`, `VSCode`, Oxford comma, US quotation, numeric
range, exclamation point, one-sentence-per-line, `Simply`, navigational
`See`, `Next steps`) produced exactly 3 findings: `Coder.GerundHeading`,
`Coder.SelectClick`, `Coder.BrandNames`.

### Counts

One rule section is one heading with an enforcement footer (`*Enforced
by ...*`, `*Documentation-only ...*`, `*Adapted from ASD-STE100 ...*`).
Sections are classified against `.vale.ini` and
`docs/.style/styles/Coder/` by an ordered test: a stated
**Documentation-only** wins, then a check that runs today, then planned.
77 total: 8 tool-checked, 25 planned, 44 documentation-only. PR 2 in
this stack adds a script that reconciles those three sources in CI so
the table and the annotations can't drift from the config again.

### Two findings recorded but not fixed here

- `Coder.BrandNames` ships at `error` but swaps only `Hashicorp` and
`HASHICORP`, though the table it's cited under lists 8 brands. `Github`
and `VSCode` pass clean. The footer now says so; widening the rule is
tracked in DOCS-889.
- `Coder.OneSentencePerLine` is set to `NO` repo-wide and re-enabled
only for `docs/.style/*.md` and `docs/.style/styles/Coder/*.md`. Rollout
tracked in DOCS-888.

### Note for the reviewer

`make lint/prose` over `docs/` currently reports a backlog of
`Coder.GerundHeading` warnings, plus the intentional `Coder.Demo*`
findings in the annotation demo. That backlog is the advisory channel
working as designed and is out of scope here, but it's the concrete
evidence behind the new sentence about findings accumulating rather than
blocking. Worth a separate cleanup decision: fix the headings, or
re-scope the rule.

Coder is a self-hosted platform for cloud development environments and AI coding agents. Workspaces are defined with Terraform, connected through a secure Wireguard® tunnel, and automatically shut down when not used. Coder Agents runs a native AI coding agent whose loop executes in the control plane on your infrastructure, with no API keys in workspaces.

  • Define cloud development environments in Terraform
    • EC2 VMs, Kubernetes Pods, Docker Containers, etc.
  • Automatically shutdown idle resources to save on costs
  • Onboard developers in seconds instead of days
  • Delegate coding work to AI agents on your infrastructure
    • Bring any model (Anthropic, OpenAI, Google, Bedrock, self-hosted)
    • No LLM credentials in workspaces, user identity on every action
    • Centralized model governance, cost tracking, and audit logging

Coder platform showing templates and a running workspace

Quickstart

Check out our install guides for other methods and a complete tutorial.

Try Coder with the install script on Linux and macOS, or grab the latest binary or installer from GitHub Releases on Windows:

curl -L https://coder.com/install.sh | sh

Start the server and open http://localhost:3000 to create your initial user, create a Docker template, and provision your first workspace:

coder server

For a production deployment, add a PostgreSQL database (version 13 or later) and an external access URL, and see our validated architectures for sizing and infrastructure guidance:

coder server --postgres-url <url> --access-url <url>

Without these flags, Coder uses a built-in database and sets up a *.try.coder.app access URL for evaluation. Use coder --help for the full list of flags and environment variables.
