Summary

  • Adds a new Recipes section to the documentation with an Error Monitoring & Alerting guide
  • Covers error triage, alert processing pipelines, real-time alert dispatch, external system monitoring, and content security scanning
  • Motivated by usage data: 39% of ALL runs (4.7M) are error handling workflows - the update docs sidebar to auto expand #1 use case by volume
  • All 6 TypeScript code samples pass type checking; all links validated

Test plan

  • Verify MDX renders correctly in local dev server
  • Verify code examples are syntactically valid (all pass pnpm test:docs)
  • Verify meta.json navigation works (Recipes section appears after AI)
  • Verify link validation passes (bun run lint:links - 0 errors)

docs(next): replace README with full integration reference
b777482
Replaces the placeholder @workflow/next README with a complete package-level reference.
The new content documents installation, withWorkflow() API usage/signature,
configuration examples, internal behavior, env vars, exports, generated files,
runtime routing, public manifest exposure, and troubleshooting.
Verified: rg -n "^## Install|^### Type signature|^### Example: object config|^### Example: async config function|^## What .* does|^## Serving the manifest publicly|^## Troubleshooting" packages/next/README.md
Verified: rg -n "WORKFLOW_TARGET_WORLD|WORKFLOW_LOCAL_DATA_DIR|PORT|WORKFLOW_NEXT_PRIVATE_BUILT|WORKFLOW_PUBLIC_MANIFEST|WATCHPACK_WATCHER_LIMIT" packages/next/README.md
Verified: rg -n "@workflow/next|@workflow/next/loader|@workflow/next/runtime|\.well-known/workflow/v1/flow/route\.js|\.well-known/workflow/v1/step/route\.js|\.well-known/workflow/v1/webhook/\[token\]/route\.js" packages/next/README.md
How to test: open packages/next/README.md and confirm all required sections and tables render correctly.
swarm:codex-swc-spec@johnlindquist
docs(swc-plugin-workflow): clarify method support and validation errors
58c54b2
Update spec.md to resolve the static/instance method contradiction, document forbidden step-expression validation errors, and add import compatibility guidance for serialization-file discovery.
Verified: git diff --check -- packages/swc-plugin-workflow/spec.md
Verified: npx --yes markdownlint-cli@0.41.0 packages/swc-plugin-workflow/spec.md --disable MD013 (fails with pre-existing file-wide markdown style issues unrelated to this change)

docs(blog): add stateless retries side-effects post
1e3c2d5
Add the requested blog draft as an exact markdown copy for agent reliability content.
Verified: cat <<'EOF' | cmp -s - .blog/stateless-retries-multiply-agent-side-effects.md && echo "Exact content match verified"
Verified: git status --short -- .blog/stateless-retries-multiply-agent-side-effects.md

docs(blog): replace stateless retries article text
d73f2ad
Overwrite the target blog file with the exact markdown content provided for this task.\n\nThis preserves all headings, prose, and fenced code examples verbatim.\n\nVerified: cat <<'EOF' | diff -u - .blog/stateless-retries-multiply-agent-side-effects.md (no diff; exit 0)\nVerified: repository Biome config does not include Markdown files (.md), so no project-scoped markdown linter applies

  • Wall Time: Total testbench time (trigger workflow + poll for result)
  • Overhead: Testbench overhead (Wall Time - Workflow Time)
  • Samples: Number of benchmark iterations run
  • vs Fastest: How much slower compared to the fastest configuration for this benchmark
