Problem

When PRs have many bot comments (dependabot, renovate, CI bots, etc.), Claude processes all of them, leading to:

• High token usage and increased Anthropic API costs
• Slower response times
• Claude potentially getting distracted by bot noise when reviewing code changes

Example: A PR with 50 dependabot + 20 renovate + 10 human comments = Claude processes all 80 comments unnecessarily.

Proposed Solution

Add two new action inputs to filter comments based on comment author username:

• include_comments_by_actor: Only process comments from specified actors
• exclude_comments_by_actor: Exclude comments from specified actors

Both should support wildcard patterns like *[bot] to match all bot accounts.

Benefits

• Token cost reduction: Up to 88% reduction in bot-heavy PRs
• Noise elimination: Claude focuses only on relevant human feedback
• Faster responses: Less data to process
• Lower API costs: Fewer tokens sent to Anthropic API

Implementation

See PR #812 for implementation details.

Example Usage

- uses: anthropics/claude-code-action@v1
  with:
    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
    exclude_comments_by_actor: "*[bot]"  # Exclude all bots

Closes #812
