Can you instead update the source, and rebuild the dist part? https://github.com/BoldPenguin/cdk-diff-action/blob/main/src/stage-processor.ts#L246 |

Instead of listing every stack individually (causing per-stack comments when the stage comment exceeds GitHub's size limit), collapse stacks with no changes into a single summary line. Only show detail for stacks with actual diffs. This prevents the per-stack comment fallback and reduces email notification spam.
When the stage comment exceeds GitHub's 65536 char limit, truncate with a notice to run cdk diff locally rather than splitting into per-stack comments (which generates N email notifications). Also collapse no-changes stacks into a summary count to minimize comment size in the common case.

- Revert action.yml from node24 to node20 (runners don't support node24 yet, causing the action to silently produce no output or comments) - Remove per-stack comment fallback when body is too long — just log a warning and let GitHub truncate on display (avoids 200+ comments and email notifications)

Description
When CDK diff output is too large for a single PR comment, the action falls back to one comment per stack. It fires ALL comment API calls in parallel via
Promise.allSettled, hitting GitHub's secondary rate limit with 100+ stacks.Fix: Replace parallel
Promise.allSettledwith sequential execution + 200ms delay between API calls.How did you test this?
Will validate via cdk-infra PR.
