Adds description frontmatter to all 380 MDX pages that were missing it, enabling AEO/SEO meta descriptions across the entire docs site.

What changed

  • Bulk backfill: 380 files across docs/, guides/, reference/, links/, troubleshooting/, and changelogs.mdx now have a description field
  • Content pages: description extracted from the first meaningful sentence of each page's body
  • API reference endpoints: hand-crafted concise action phrases (e.g. "Query a saved Insights report", "Delete a warehouse pipeline by ID")
  • Navigation/card pages and link redirects: custom descriptions written from title/URL context
  • Fixed extraction bugs: ~20 files where the script pulled import statements or JSX comments instead of prose were corrected manually

Example

---
title: Boards
description: "Collect your reports into a single view"   # was missing
---

The only file intentionally left without a description is snippets/utils/constants.mdx, which is a bare JS module with no frontmatter.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains from the previously reported findings.

Important Files Changed

Filename Overview
guides/guides-by-use-case/empower-your-team/mcp.mdx The description now uses valid single-quoted YAML around its internal double quotes.
docs/tracking-methods/sdks/nodejs.mdx The previously truncated metadata is now a complete, page-relevant description.
docs/tracking-methods/sdks/python.mdx The server SDK description was rewritten as a complete summary.

92 of the 380 backfilled descriptions were first-sentence extractions that
failed as descriptions: 17 data-pipelines pages shared one sentence, 6 SDK
pages said only 'Please refer to our Quickstart Guide', several captured JSX
fragments (ProductCollectiveLogo) or truncated mid-sentence, and 15 opened
with 'This page/guide'. Rewrote each from the page's actual content
(80-155 chars, answer-first, unique repo-wide). Also fixed 6 pre-existing
duplicate descriptions on the MCP industry pages ('Use Cases and Sample
Prompts' x6). 59 short-but-accurate API reference stubs left for the
OpenAPI enrichment issue (TOF-447 scope).

Reviewed all 380 added descriptions and pushed fixes directly to this branch (commit f463107).

What was solid: full coverage (443/443 pages now have a description, zero missing on this branch), clean diff shape (one frontmatter line per file, nothing else touched), and roughly three-quarters of the descriptions were usable.

What I fixed (98 files):

- 17 data-pipelines pages shared one identical generic sentence; each now names its own destination and pipeline type.

- 6 SDK pages said only "Please refer to our Quickstart Guide"; each now describes its platform and setup path.

- JSX fragments captured as descriptions ("ProductCollectiveLogo,", "AndreessenHorowitzLogo,"), a "Last updated January 21st, 2026" description on the Session Replay privacy page, and blockquote markers on 6 legacy API pages.

- 13 truncated mid-sentence, 15 opening with "This page/guide", 3 SSO pages describing the generic SSO doc instead of their own provider, and assorted duplicates (quickstart x3, autocapture x2, agent x2).

- Also fixed 6 pre-existing duplicates outside the PR's additions: the MCP industry pages all read "Use Cases and Sample Prompts".

Deliberately left: 59 short-but-accurate API reference stubs ("Delete an experiment by ID") — the OpenAPI enrichment issue covers those properly at the spec level. Also left the funnels hub/overview duplicate pair; that's the thin-hub consolidation issue's scope.

Every rewrite is 80-155 chars, unique repo-wide, derived from the page's actual content, and YAML-validated. Spot-checked factual claims (Android .aar/Maven, Snowflake storage integration + IP allowlist, GTM custom template) against page content.

Ready for your final look and merge, @tylergoerzen.

@greptile-apps review

Addresses the two Greptile P1 review comments on #172 that were resolved
without a code change, plus the truncated descriptions its second comment
referred to generically.

Malformed frontmatter (both failed yaml.safe_load, so Mintlify would drop
the description or fail the build):

- guides/.../empower-your-team/mcp.mdx: unescaped internal double quotes
  terminated the scalar early; switched to a single-quoted scalar.
- reference/profile-set-property-once.mdx: `\$` is not a valid escape in a
  double-quoted YAML scalar; rewrote as a plain action phrase.

Truncated mid-clause descriptions rewritten as complete summaries:

- docs/features/saved-metrics-and-behaviors.mdx
- docs/tracking-best-practices/hot-shard-limits.mdx
- guides/guides-by-workflow/data-privacy.mdx
- reference/ingestion-api-authentication.mdx
- reference/rate-limits.mdx
- troubleshooting/faqs.mdx

Verified: all 386 changed files now parse as YAML and every one has a
description.

@copilot resolve the merge conflicts in this pull request

Resolved — the only conflict was a modify/delete on docs/slack-bot.mdx. Since that file was intentionally deleted on main (commit fe9086b, redirected to /docs/mixpanel-agent), I accepted the deletion and finalized the merge.

Greptile's second P1 comment was right about python.mdx: the earlier fix
pass caught nodejs.mdx but left its siblings, and a repo-wide re-scan of
all 385 changed pages turned up six descriptions still cut off mid-clause
by the backfill script's character limit.

Rewritten as complete summaries:

- sdks/python.mdx, sdks/ruby.mdx, sdks/go.mdx, sdks/php.mdx — all four
  ended on "isn't directly" or "won't run"; now follow the same
  "Install and configure the Mixpanel X SDK to..." shape as the
  client SDK pages.
- cohort-sync/integrations/marketo.mdx — ended on "export cohorts into".
- migration.mdx — ended on a stray "Our" after an emoji.

Also rewrote sdks/ios.mdx, which parsed fine but described only its own
deprecation and never said what the SDK does.

Verified: all 385 changed pages parse as YAML, every one has a
description, and none exceeds 170 characters.

@greptileai review

Pushed ae16e07, which addresses the second P1 comment. python.mdx and three sibling server SDK pages (ruby, go, php) still ended mid-clause; all four are rewritten, along with marketo.mdx, migration.mdx, and a weak ios.mdx description.

The malformed YAML in mcp.mdx was fixed earlier in fd5c449, along with a second broken scalar in reference/profile-set-property-once.mdx.

Re-scan of all 385 changed pages: 0 YAML parse failures, 0 missing descriptions, 0 truncated, none over 170 characters.

Too many files changed for review (385 files, 100 file limit).

Bypass the limit by tagging @greptile-apps to review.

Completes rec #20 Part B's gate list.

- New check_openapi.py: parses all 14 specs, requires openapi/info/paths,
  and resolves every local $ref. Uses openapi-spec-validator for full
  schema validation when installed, and still runs structurally without
  it. Passes on all 14 specs today; rejects a spec with a dangling $ref.
- check_frontmatter.py now requires a non-empty description and fails on
  duplicate rendered titles, which rec #11 asked for.
- Pin actions/checkout and actions/setup-python to commit SHAs, matching
  stale.yml. Collapse four near-identical jobs into one with ordered
  steps, and add a concurrency group.

MERGE ORDER: the frontmatter gate is red until #172 (description
backfill) and #178 (title dedupe) land. Verified against the #172 tree:
all description errors clear, leaving only the duplicate titles that
#178 resolves. Merge this last, as the plan intends.

Rec #11 asks for a CI uniqueness test on rendered titles, which only
passes at zero duplicates. Three pairs survived the first pass:

- Data Pipeline Integrations: the old-pipelines copy is now marked
  (Legacy), keeping "Integrations" as its sidebar label
- Lookup Tables: the reference page is the API, so it becomes
  Lookup Tables API
- Mixpanel Headless: the guide gets the benefit-style title, leaving the
  bare product name to the docs page

Verified zero duplicate titles across the tree, so the frontmatter gate
in #180 can enforce uniqueness once this and #172 land.
