This PR

  • Adds @signalwire/docusaurus-plugin-llms-txt to generate llms.txt, llms-full.txt, and a .md copy of each docs and spec page at build time.
  • Adds scripts/rehype-llms-cleanup.ts to clean up the rendered HTML before conversion: strips heading permalinks, restores code block languages, labels tab panels, and replaces YouTube embeds with links.
  • Excludes community, search, and generated category pages. flagd and the GitHub org are listed under ## Optional.
  • Removes the hand-curated static/llms.txt from docs: add llms.txt index #1548, since it's now generated.
  • Adds a description to the synced SDK pages. Without it, Docusaurus used the "automatically generated" HTML comment, so both the llms.txt entries and the page meta descriptions were <!--. Re-ran yarn update:sdk-docs, which also pulls in the latest SDK README changes.

Example output

Generated from a local build, in this gist:

  • llms.txt: the generated index
  • evaluation-api.md: tabbed multi-language examples
  • getting-started-node.md: a tutorial with JavaScript/TypeScript tabs
  • sdk-server-go.md: an SDK page synced from go-sdk
  • spec-flag-evaluation.md: a spec page

Related Issues

Relates to #1482, follow-up to #1548.

📝 Walkthrough

Walkthrough

SDK references now show updated release details and page metadata. Docusaurus also configures an LLM text output plugin and a HAST cleanup transformer; the previous static llms.txt index was removed.

Changes

SDK reference updates

Layer / File(s) Summary
SDK release details
docs/reference/sdks/client/dart.mdx, docs/reference/sdks/client/swift.mdx, docs/reference/sdks/server/dart.mdx, src/datasets/sdks/sdk-compatibility.json
The Dart references update release versions and status, installation guidance, and release-procedure wording. The Swift reference and compatibility data show version 0.7.0; the Dart server reference and compatibility data show version 0.1.0.
SDK page metadata
docs/reference/sdks/client/*, docs/reference/sdks/client/web/*, docs/reference/sdks/server/*, docs/reference/sdks/server/javascript/*
SDK reference pages gain descriptions and refreshed generated timestamps.

LLM text output

Layer / File(s) Summary
HAST content cleanup
scripts/rehype-llms-cleanup.ts
The new transformer removes comments and selected controls, rewrites video containers, rebuilds code blocks, and emits tab-panel contents with labels.
LLM text plugin integration
docusaurus.config.ts, package.json, scripts/process-sdk-readmes.ts, static/llms.txt
Docusaurus configures the LLM text plugin, exclusions, route rules, and cleanup plugin. SDK README generation adds descriptions, and the previous static index is deleted.

Merge Risk: 🔵 Low · up to 62607

Generated LLM documentation includes a category page intended to be excluded. This is a limited output-quality issue that can be fixed before merging or accepted for follow-up.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 62607

The inspected changes generate text from rendered documentation without adding a request-time endpoint or granting agent permissions. No concrete security regression was substantiated. Complete-publication and deployed-output guarantees remain partly unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — For the inspected path, someone able to change documentation content can influence its generated text representation and aggregation. The affected outputs are documentation files; the added dependency executes with the build process's authority. No additional tenant, service or data-store authority was demonstrated.

Trust Boundaries and Controls

  • observed — Route filtering occurs before publication and applies content-type and exclusion settings. Cleanup consumes rendered content on a separately parsed tree and preserves document-derived text and links; it is not a sanitization or authorization boundary for downstream agents.

Resilience and Maintainability Implications

  • inferred — Page-local parsing and the cleanup's lack of mutable closure state contain transformation failures to the current conversion. Repeated transformation does not introduce additional authority or cross-page state. This isolation does not imply atomicity of the complete output set.

Hardening Proposals

  • proposed — Consider checking expected page and index completeness before publishing a staged documentation build, so skipped conversions cannot silently omit security guidance from generated text. This is a publication-integrity proposal, not an observed security finding.

Exclude specification category pages.

excludeRoutes covers /docs/category/** but not /specification/category/**. The example llms.txt includes /specification/category/sections.md, contrary to the stated category-page exclusion. Add /specification/category/** to this list. (gist.github.com)
