# AI Visibility > Review documentation PRs, pages, or navigation for visibility to AI consumers — crawlers building training corpora, RAG retrievers, and autonomous agents — across the model lifecycle (pre-training, training, post-training, inference/RAG). Use whenever the user asks how docs appear to LLMs or AI agents, asks to review a PR or page for AI visibility, discoverability, GEO, or agent experience, or mentions llms.txt, llms-full.txt, markdown twins, JSON-LD, canonical links, sitemap-md, or "how would a model navigate this" — even if they don't say "AI visibility" explicitly. Also covers SEO-relevant frontmatter review (titles, descriptions, canonicals) since the same metadata drives both search snippets and AI retrieval. - Skill: `influxdata/ai-visibility` (Agent Skill) - Install (CLI): `npx skillmds@latest add influxdata/ai-visibility` - Raw SKILL.md: https://api.skillmd.com/api/skills/influxdata/ai-visibility/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Marketing & Growth - Author: influxdata (https://skillmd.com/u/influxdata) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/influxdata/ai-visibility --- # AI visibility review Review documentation the way AI systems consume it, not the way humans read it. Different consumers read different surfaces at different times: crawlers snapshot HTML for training corpora, RAG retrievers fetch Markdown twins and chunk them, and agents walk URLs and bind to machine-readable contracts. A page can be excellent for human readers and invisible — or misleading — to every one of these consumers. This review finds those gaps with evidence, not assumptions. ## Inputs Accept any of: - **A PR**: `gh pr view ` and `gh pr diff ` for the change; the PR preview site for rendered output (see the reference file for preview URL shape and its known artifacts). - **Page URLs**: production or preview. - **A section or product**: review the navigation graph and discovery paths, not just individual pages. ## Step 0: Scope the review before fetching anything State a one-paragraph review plan first: what the target is, which pages you will fetch, and which layers matter most for this target. An unscoped review fetches everything at full depth and burns most of its budget proving things that were never in doubt. - **PR**: review the changed pages and the discovery paths they depend on. Pre-existing product-wide gaps get one line and a pointer, not a re-investigation. - **Single page**: full depth on that page; discovery paths checked once. - **Section or product**: sample, don't enumerate. The product root, one or two task pages, one reference page, and one API page (if any) reveal every defect class; reading all 285 pages reveals the same classes slower. Use corpus-level greps (`llms-full.txt`) to measure how widespread a defect is after you find it on a sampled page. - **Match depth to the product**: for a GUI product, the agent-harness layer is "what can be done headless" (install, config files), not API contracts. For a legacy product, lead with currency and compatibility-statement checks. Don't run every layer at uniform depth when the target makes a layer mostly moot. ## Step 1: Fetch the surfaces — verify, don't assume A review is read-only. **Never build the site (`hugo`, `yarn build:*`, docker) for a review** — everything a review needs is already published (production, the PR preview) or readable in source (templates, data files, content). Local builds take minutes, stall in constrained environments, and leave artifacts in the working tree, and they verify nothing that a fetch plus a source read doesn't. If a claim can't be verified from published artifacts and source, label it an inference and include the one-line command that would verify it. Every claim in the report must come from a fetched artifact or a read source file. Three gotchas that produce false findings if skipped: - **Always `curl --compressed`.** Production serves gzip; raw bytes look like binary garbage and a naive fetch "finds" nothing. - **Minified HTML drops attribute quotes.** `grep '`. Match with quote-tolerant patterns (for example `]*canonical[^>]*>`) or you will report present metadata as missing. - **Check preview AND production before calling something a bug.** See [PR Preview](../../../DOCS-DEPLOYING.md#pr-preview) for deployment behavior and known parity gaps. Its advertised Markdown twins 404, so check twin fidelity on production or staging. Other preview-only defects need investigation; don't dismiss them as expected prefix behavior. For each page, capture: | Surface | What to check | | ---------------- | ---------------------------------------------------------------------------------------------- | | `` | ``, meta description, `<link rel=canonical>`, `<link rel=alternate type=text/markdown>` | | JSON-LD | Which `@type` nodes exist, and whether `@id` references resolve (entity graph coherence) | | Headings | h2/h3 hierarchy, stable anchor ids, question-shaped phrasing | | Markdown twin | Exists? Served as `text/markdown`? Conversion quality (see Step 3, RAG) | | robots / noindex | Anything blocking AI crawlers from this path | ### Frontmatter and SEO signals Frontmatter is the single source for the page's `<title>`, meta description, JSON-LD fields, and twin metadata — one weak field degrades every surface at once. Check in the source files (not just rendered output): - **`description`**: present, specific to the page, roughly one to two sentences. A missing description falls back to generic text; a duplicated description (for example, a section landing reusing the product root's) makes search snippets interchangeable and page embeddings near-identical — the retriever can't tell the pages apart. Grep for duplicates across the section; don't check pages one at a time. - **`title`**: distinct within the product, matches how users phrase the task. Title is the strongest single retrieval and snippet signal. - **Canonical intent**: self-canonical by default; a cross-product canonical (shared content pointing at the canonical edition) is a deliberate consolidation — verify it points where intended, and flag it as a trade-off, not a bug, when it's by design. - **Dates**: `lastmod`/`date` flow into twins, JSON-LD `dateModified`, and sitemap `<lastmod>` — stale dates on current content undersell freshness to both rankers and agents. ## Step 2: Walk the discovery paths An AI consumer can only use what it can find. Walk each path end-to-end and record where it works and where it dead-ends: 1. **`llms.txt` path**: site root `llms.txt` → the product or section entry → its artifacts. Check all three granularities: the per-section `index.section.md` links, the per-page `.md` twins, and the per-product `llms-full.txt` flattened corpus. Verify the corpus file exists (fetch it, don't trust the link) and contains the pages under review. A product missing from `llms.txt` — or listed without a `llms-full.txt` corpus — is invisible to every llms.txt-first agent regardless of page quality. 2. **Sitemap path**: `sitemap.xml` and `sitemap-md.xml` → page and twin URLs. 3. **HTML head path**: canonical + markdown-alternate + JSON-LD from any page reached by crawl or search. 4. **In-site navigation**: hops from the product root to the page; menu placement; `related:` links; anchor-deep links. Report the paths as a table (works / dead end), and trace dead ends to their cause in code or data — the fix usually lives in a template, a build script, or a data file, not in the page (see the reference file for where these live in this repo). ## Step 3: Analyze per consumption layer Judge each finding by which lifecycle stage it affects. The same page serves four consumers with different needs and different latencies: ### Pre-training / training (months; shapes the next model generation) - Is the content server-rendered, public, and crawlable? Anything behind authentication, a running instance, or client-side JS is absent from every training corpus, permanently. - What concrete facts can a model memorize from this page? Ports, paths, prefixes, version numbers, header schemes. Vague prose trains nothing. - Name the hallucination risk that gaps create: when docs publish an API's conventions but not its surface, future models invent the missing endpoints by analogy with products they know better. For new products, the first crawl impression is the seed corpus — thin coverage now is parametric ignorance later. ### Post-training (instruction and agentic tuning) - Are examples self-contained and runnable — imports and auth visible, no "as in the previous example"? Instruction-tuning corpora favor Q\&A-shaped sections and copy-adaptable code. - Do placeholders follow a consistent, machine-recognizable convention (UPPER\_SNAKE tokens with replace-instructions)? ### RAG / retrieval (weeks; the layer you can move now) - **Chunk quality**: each h2 section should stand alone with the answer in its first sentence. Retrievers extract passages without surrounding context. - **Twin fidelity**: read the generated Markdown twin, don't trust that it mirrors the HTML. Look for conversion bugs (lost whitespace around links and code spans, broken tab-group rendering) and for repeated boilerplate (beta banners, sunset notices) consuming the first chunk of every page in a section — that makes section pages embed near-identically and surfaces the banner instead of the answer. - **The dead-end test**: for the page's core question, what does a docs-grounded assistant retrieve and what can it actually answer? "Check your instance" or "see the UI" is a terminal non-answer for every hosted assistant. ### Agent harness (immediate) - Can an agent execute the page's guidance headlessly? Token auth in a fenced command beats "log in via the browser." - Are machine-readable contracts published or fetchable (OpenAPI, JSON schema, MCP)? An interactive UI is not a contract. - Are URL shapes predictable and anchors stable enough to construct from a task description? Count the hops from product root to the answer. ## Step 4: Report Lead with the verdict — what's solid, what's broken, in two or three sentences. Then: - **Facts with evidence.** Every finding cites the fetched URL, file path, or command output that proves it. Distinguish confirmed facts from inferences. - **Separate findings by level.** Page-level (fix in the content), product-level (fix in data or config — for example a missing corpus entry), and pipeline-level (fix in shared templates or converters, affects all products). Mislabeling a pipeline bug as a page bug sends the fix to the wrong place. - **Prioritized recommendations.** Order by leverage: discovery-path breaks first (they gate everything else), then machine-readable contract gaps, then content coverage, then twin hygiene. - **Credit what works.** Inherited infrastructure (head links, JSON-LD, sitemap entries) that the change gets for free belongs in the report — it scopes the real gaps and prevents re-litigating solved problems. Produce the report; don't file anything unsolicited. Then offer follow-ups. If the user accepts: - File pipeline-caused findings as **general** issues citing the observed pages as evidence — not product-scoped issues, which misleads triage. - For small mechanical fixes (a cross-link, a frontmatter field), prefer a direct PR over an issue. ## Repo specifics Before reviewing anything on docs.influxdata.com or in this repo, read [DOCS-AI-VISIBILITY.md](../../../DOCS-AI-VISIBILITY.md) — it maps the three Markdown artifact layers, the eligibility predicates and their source files, the products.yml gate that controls `llms.txt` inclusion, and the PR preview workflow's known artifacts. Reviews that skip it rediscover (or misdiagnose) the same plumbing every time. [DOCS-DEPLOYING.md](../../../DOCS-DEPLOYING.md#llm-markdown-generation) covers how those artifacts are generated, if a finding traces back to the build rather than to content.
