Normalizes non-standard code-fence language tags across `docs/**` so a strict highlighter (Shiki, used by Fumadocs) won't fail the build on an unrecognized language, and unifies redundant synonym tags onto one canonical form per language. The current renderer (Speed-Highlight) detects the language from the code content, not the fence label, so this drift wasn't visible until now. ## Changes - `hcl` -> `tf` (199 fences, including indented ones nested in numbered/bulleted lists). Shiki ships `hcl` and `terraform` as two distinct grammars (not aliases); every `hcl`-tagged fence in `docs/**` is actually Terraform resource/data/provider syntax, so the more specific `terraform` grammar is correct for all of them. `tf` is Shiki's own alias for that grammar, and it's also what GitHub's own markdown renderer resolves to the same HCL/Terraform highlighting. - `pwsh`/`powershell` -> `ps1`. Both `ps` and `ps1` are registered PowerShell aliases in Shiki, but on GitHub's renderer only `.ps1` is a registered file extension (`.ps` isn't), so `ps1` renders identically to `powershell` there today while bare `ps` would silently lose highlighting. - `env` -> `dotenv` (a dedicated Shiki grammar for `KEY=VALUE` files) - `text`/`output`/`none`/`url` -> `txt`. Same built-in plain-text fallback either way, just shorter. - `Dockerfile` -> `dockerfile` (lowercase) - `bash`/`shell` -> `sh` (732 fences). Shiki and GitHub both alias all three to a single shell grammar; this was already the style guide's stated preference, just not enforced across the existing corpus until now. - `markdown` -> `md` (4 fences). Alias of the same grammar in both Shiki and GitHub. - `jsonc` -> `json` (1 fence). The block has no comments or trailing commas, so it doesn't need the comments-capable grammar. - `ts` -> `tsx` (2 fences, `docs/about/contributing/frontend.md`). Verified the actual content tokenizes identically under both grammars, and a sibling block in the same file already needs `tsx` for real JSX, so unifying to one tag is safe for this file. Documented a caveat: `tsx` mis-tokenizes the legacy angle-bracket type-assertion syntax (`<Type>value`), which is invalid in real `.tsx` files anyway, so use `value as Type` instead. - `yml` -> `yaml` (1 fence) - Updated `docs/.style/style-guide/formatting.md` to document all canonical tags `promql` (2 fences) and `caddyfile` (2 fences) are left as-is. Shiki doesn't bundle a grammar for either, so they need a custom grammar registration when the site adopts Shiki, rather than degrading to `txt`. Tracked as follow-up work under DOCS-118 and [DOCS-544](https://linear.app/codercom/issue/DOCS-544/vendor-a-local-promql-grammar-for-shiki-syntax-highlighting) (promql). Does not touch `offlinedocs/`. Linear: [DOCS-476](https://linear.app/codercom/issue/DOCS-476/normalize-docs-code-fence-languages-de-risk-shikifumadocs) <details> <summary>How the fence tags were verified</summary> Each tag was tested against a real `shiki@latest` highlighter instance (`codeToHtml`/`codeToTokens`) and cross-checked against GitHub's `@wooorm/starry-night` grammar sources (the renderer that actually displays these `.md` files today, in repo browsing and PR diffs), since that's what determines whether brevity is safe before Shiki adoption: ```text FAIL env -- Language `env` is not included in this bundle. FAIL Dockerfile -- Language `Dockerfile` is not included in this bundle. FAIL promql -- Language `promql` is not included in this bundle. FAIL caddyfile -- Language `caddyfile` is not included in this bundle. FAIL pwsh -- Language `pwsh` is not included in this bundle. FAIL output -- Language `output` is not included in this bundle. ``` `hcl` doesn't error in Shiki, since it's a real grammar, but that's exactly the trap: it was silently rendering every fence with the generic HCL grammar instead of the Terraform-specific one. Every `hcl`-tagged fence in `docs/**` was manually checked against `origin/main` and is genuinely Terraform content. For `ts`/`tsx`, tokenizing the actual doc content confirmed identical output under both grammars; a synthetic test with the legacy angle-bracket cast syntax confirmed `tsx` degrades on that specific construct, which the style guide now calls out. The first normalization pass only matched fence tags at column 0 (`^```tag$`), missing tags indented inside numbered/bulleted lists. A follow-up pass caught the remaining occurrences at any indentation level. </details> --- *This PR description and the underlying changes were prepared with Coder Agents assistance.*

Advisor
Note
This feature is experimental. Pin a release before broad rollout and review the release notes before upgrading.
Enable the experiment
coder server --experiments=chat-advisor
Or set the environment variable:
CODER_EXPERIMENTS=chat-advisor
What it does
Lets a root agent pause its current turn and request strategic guidance from a separate, single-step model call. The advisor sees recent conversation context, runs without any tools, and returns concise advice for the root agent rather than the end user. While active, it is the only tool the root agent can call for that turn.
Useful for planning ambiguity, architectural tradeoffs, debugging strategy after repeated failures, or risk reduction before a destructive operation.
Configuration
Once the experiment is enabled, configure the advisor under AI Settings > Coder Agents > Advisor.
| Field | Default | Notes |
|---|---|---|
| Max uses per turn | 0 (unlimited) |
Caps how many times the root agent can call the advisor in a single chat turn. Must be a non-negative integer. |
| Max output tokens | 0 (server default) |
Caps the advisor model's response length. 0 uses the server default of 16,384 tokens. Must be a non-negative integer. |
| Advisor model | Use chat model | Optional dedicated chat model config for the advisor. When unset, the advisor reuses the root agent's model. |
| Reasoning effort | Model default | Overrides the selected advisor model's reasoning effort. Available only when the model supports selectable effort. |
The advisor is not available in plan mode or to subagents. Failed advisor invocations refund the per-turn budget, and advisor calls are not metered against the root chat's usage limit.
