cookbook-review-pr	Review a pull request against the SGLang Cookbook (docs_new/, Mintlify) contribution checklist — the config-driven format (per-model config + benchmarks JSX consumed by the shared _deployment.jsx / _playground.jsx engines). Run with /cookbook-review-pr <PR number>.

Cookbook Review PR

Fetch the diff, run the checklist, report what you find. The cookbook is config-driven: shared engines (_deployment.jsx, _playground.jsx) with NO model-specific code; each model is a data config (+ optional benchmarks) under src/snippets/configs/<vendor>/ plus an MDX page. This checklist targets that layout. Field-schema detail lives in .claude/skills/cookbook-add-model/references/authoring-reference.md — defer to it rather than restating.

Usage

/cookbook-review-pr <PR number>

Steps

1. gh pr view <N> --repo sgl-project/sglang --json title,body,files,author,baseRefName,headRefName,commits,reviews
2. gh pr diff <N> --repo sgl-project/sglang
3. gh pr list --repo sgl-project/sglang --state open --search "<model name>" (duplicate check)
4. Run every checklist item against the diff.
5. Output per-file verdicts + overall recommendation.

Checklist

1. File hygiene

• A cookbook PR should only touch: docs_new/src/snippets/configs/<vendor>/*.jsx (config + benchmarks), docs_new/cookbook/**/*.mdx, docs_new/docs.json, docs_new/cookbook/<category>/intro.mdx (vendor card), docs_new/cards/logos/<vendor>.png (new vendor only). Flag stray files (settings.local.json, lockfiles, IDE configs).
• Pages must be .mdx, not .md. Files end with a trailing newline. Check commit history for unrelated commits accidentally included.
• Engines untouched: _deployment.jsx / _playground.jsx should NOT change in a model-add PR (adding a model is data-only). Engine edits = a separate axis/feature PR (see cookbook-add-model/references/engine-axis.md); review them against that checklist.

2. Config quality (the per-model config)

• Single export const config = { ... } literal — no function calls, spreads, fragment refs, or IIFE (Mintlify re-evals at hydration → ReferenceError).
• No !(x in y) anywhere (Mintlify AST walker crashes) — use obj.key === undefined.
• supportedHardware ⊆ HARDWARE_CATALOG (in _deployment.jsx) ∪ config.hardware. A model-specific GPU the shared catalog lacks must be declared in config.hardware ({id,label,vram,vendor}), not added to the engine catalog.
• placeholders declares every {{KEY}} used in curl or any cell.
• modelNames covers every cell (by hw|variant|quant triple or variant|quant pair).
• dockerImages covers the hw ids that have cells (else users hit the :dev fallback).
• multiNodeHints present ONLY for hw whose fabric needs manual NIC env (e.g. gb200 NVL72) — NOT every multi-N hw (standard-IB DeepEP / Marlin multi-node don't need it).
• github.cookbookModel matches the issue-template model dropdown value.
• playgroundFeatures axes are pruned to what the model supports — no empty/stub axes (megamoe only on Blackwell MoE; hisparse only DSA-style; pdDisagg.router only with a PD topology).
• No leftover __TOKEN__ — the config was stamped from the template and every placeholder is filled (grep -rn '__[A-Z_]*__' on the new config/benchmarks/MDX returns nothing).
• All-hardware considered: every supportedHardware id (from the catalog or config.hardware) has ≥1 cell OR is a deliberate greyed "coming soon"; AMD was pruned or kept on purpose (not a leftover template family).

3. Cells / 5-dim matrix

• Every cell match has EXACTLY the 5 keys (hw, variant, quant, strategy, nodes).
• env / flags are flat literals (only {{PLACEHOLDER}} subst) — no shared commonFlags reference (Mintlify won't inline it).
• NO --nnodes / --node-rank / --dist-init-addr literals in multi-node cells (the renderer injects them from match.nodes).
• NO literal --host / --port — use {{HOST_IP}} / {{PORT}}.
• Flag order: --model-path first, then parallelism, then MoE, then tuning, --host/--port last (the playground's insert anchors assume this).
• TP/memory sanity: model_weight_GB / (tp × gpu_mem) fits with ~20–30% headroom (BF16 ≈ params×2 GB, FP8 ≈ ×1, FP4 ≈ ×0.5; MoE uses total weight, not active params).

4. Benchmarks

• Each benchmarks[] entry's match tuple corresponds to a real cell.
• defaultAccuracy keys ∈ ACCURACY_LABELS (and benchmarkCommands.accuracy).
• A benchmark's quantization must match a variant actually listed — (BF16) on a model that only released FP8/FP4 is a factual bug.
• benchmarkCommands.speed is python3 -m sglang.bench_serving (the workload), separate from the sglang serve deploy command.
• sglang_version is a real build the author ran (a release, or dev/nightly) — not a guessed/placeholder value (no leftover 0.0.0).

5. Doc ↔ config parity (the #1 finding)

• Any sglang serve command shown in MDX prose (config tips, benchmark section) must equal what the engine emits from the corresponding cell — same flags, same order. Drift here is the most common review miss.

6. Commands / port

• Launch uses sglang serve — flag any python -m sglang.launch_server / python3 -m sglang.launch_server (deprecated). The engine already emits sglang serve; guard against prose/cells reintroducing the old launcher.
• Port 30000 everywhere (launch, curl, client base_url, bench) — flag 8000. Launch port must match client/curl port on the same page.

7. Frontmatter

• Every new MDX page has title: and metatags.description: (a real one-line value prop, not copied from another vendor).
• tag: NEW only for genuine new launches; when one is added, stale tag: NEW on older pages should be dropped in the same PR (grep -RlE "^tag: NEW" docs_new/cookbook/).
• MDX imports BOTH Deployment and Playground from /src/snippets/... (absolute).
• Deploy heading slugs to deployment (or deploy), Playground to playground — so "↑ Switch base" and "Open the Playground →" scroll. No numbered headings for these two.

8. Navigation & homepage

• New page → docs_new/docs.json updated: under the right vendor group inside navigation → Cookbook → Autoregressive Models, root-relative, no .mdx: cookbook/<category>/<Vendor>/<Model>.
• Homepage <Card href> in docs_new/cookbook/<category>/intro.mdx points to the vendor's flagship; new vendors get a new <Card> + a logo at docs_new/cards/logos/<vendor>.png — 940×525 RGBA transparent, icon-only (no wordmark), lowercase filename, tracked via git add -f (*.png is gitignored repo-wide). Card order matches the docs.json nav order.
• Don't change docs_new/cookbook/intro.mdx for individual model adds (top-level only).

9. Links & factual

• HuggingFace URLs resolve to a real model. License section matches the actual HF license (don't copy from another model). Docker images from lmsysorg/sglang; no sgl-project-dev. The image tag is a real build (a release the author ran, or :dev/nightly) — not a guessed version.
• Internal links root-relative, no extension (/cookbook/.../<Model>); flag .md/.mdx or ../-relative links. docs.sglang.io is canonical.
• No Google-Drive image links (don't render). Shell placeholders are export VAR=<value>, not ${VAR} (a bash no-op).

9b. MDX authoring (Mintlify) — detail in cookbook-add-model/references/mintlify-authoring.md

• Forbidden syntax: no Docusaurus admonitions (:::), @site/@theme, GitHub alert blocks (> [!NOTE]), markdown pipe tables (use JSX <table>), inline <details>, or unknown components. <CardGroup>/<Card> only on category intro.mdx, not model pages.
• Code fences are labeled (e.g. python Example / bash Command / text Output after the opening fence); a fenced block nested inside another uses four backticks outside.
• Every runnable invocation block is followed by **Output Example:** + a text Output fenced block (real output, or Pending update... only with user acknowledgement).
• Reasoning-parser example matches the parser's output shape: separate-field (reasoning_content + content) vs inline <think> tags parsed out of content.
• No hardcoded sampling params (temperature / top_p) in sample code (SGLang uses generation_config.json defaults); listing them in §1 informationally is fine.

10. Quantization rules

• FP4 is Blackwell-only (B200/B300/GB300) — never AMD; AMD FP4 chips must be disabled.
• BF16 / FP8 work on NVIDIA and AMD. FP8 configs adding --kv-cache-dtype fp8_e4m3 should note the accuracy trade-off.

11. Scope

• Changes match the PR title. Flag global changes hiding behind a platform-specific title (e.g. an "H200 FP8" PR that adds a flag to ALL cells). Unmentioned side-fixes belong in the PR body.

12. Duplicate PRs

• Another open PR for the same model? Flag it; compare completeness; note merge-conflict risk on docs.json + the vendor card; flag a superseded older PR by the same author.

13. Build / validate

cd docs_new
mint validate
mint broken-links

Optional: mint dev for a visual smoke test.

14. Reviewer feedback

• gh api repos/sgl-project/sglang/pulls/<N>/comments — have prior reviewer requests been addressed? Unresolved requested-changes should be flagged.

15. Grammar & spelling

• Check added/changed prose for typos and grammar (e.g. "recommend" vs "recommended"). Flag each with the exact wrong text + correction.
