Reproducible Docs With Guarantees

When updating technical docs, write them as executable, environment-aware workflows and as reliable behavioral descriptions.

1) Encode real constraints/workarounds

• Call out tool/platform limitations explicitly and include the safe alternative patterns.
  • Example patterns to document:
    • Trusted Types restrictions: prefer document.createElement(...) + textContent over innerHTML.
    • UI/selector quirks: specify how to interact when accessible names/roles are missing.

2) Make workflows deterministic

• State and enforce preconditions so “what you’ll see” matches the docs:
  • Clean state before starting (clear tabs/toasts/modals in a separate step).
  • Use a safe git strategy so examples don’t depend on uncommitted local state.

  # Example doc pattern
  git commit -am "Update for demo"   # ensure clean state
  git switch --detach "$(git merge-base HEAD origin/main)"  # base build
  npm run build-fast -- --client-only
  # record "before"
  git switch -  # restore demo change
  npm run build-fast -- --client-only
  # record "after" with an in-script assertion (e.g., toast appears only after change)
  

3) Prevent misleading outputs

• For demos/comparisons, include verification in the scripted workflow (assert expected outcome before/after) so the recording can’t silently show the wrong state.

4) Describe behavior with stable guarantees, not brittle constants

• If exact operational numbers (intervals/attempt counts) aren’t part of a stable contract, document the guarantees/bounds and triggers instead of hardcoding exact values—keeping the docs resilient while tests still validate correctness.

Applying this consistently will make documentation both actionable for developers and trustworthy over time.
