README

T4 is the lint-only tier. There are no renders to diff — the skill is graded on whether it correctly refuses to translate each case (and recommends the runtime interop pattern from PR #214 instead) or, where appropriate, translates after dropping warning-level decorations.

Each cases/*.tsx file is a minimal Remotion composition that demonstrates one specific pattern. The skill should:

1. Run scripts/lint_source.py over the source.
2. Compare the JSON output to expected.json for that case.
3. Take the documented skill_action:
   • refuse_translation_recommend_interop — print the rationale + link to the PR #214 interop guide; do not produce HF output.
   • drop_lambda_code_translate_remainder_if_clean — drop the @remotion/lambda code with a note; translate the rest only if no other blockers are present.
   • translate_after_dropping_wrappers — translate normally; drop useCallback / useMemo / delayRender wrappers.
   • inline_hook_body_if_pure — inline the custom hook’s body if it’s a pure derivation of useCurrentFrame; otherwise bow out.

Cases

Validation

The script runs lint_source.py against each case and asserts:

• Each expected blocker rule fires with severity blocker.
• Each expected warning rule fires with severity warning (or stronger).
• lint_source.py‘s exit code is 1 when blockers are expected, 0 otherwise.

T4 passes when every case matches its expected output. No renders involved.
