Summary

Agent frontmatter tools: entries in dt-learning-tutor.agent.md and implementation-validator.agent.md use bare tool names (e.g., run_in_terminal, read_file) instead of the official VS Code tool identifiers required by the frontmatter linter.

Affected Files

Expected Behavior

Frontmatter tools: entries should use official identifiers (e.g., github.copilot-chat#terminalCommand instead of run_in_terminal).

Acceptance Criteria

• All bare tool names replaced with official VS Code tool identifiers
• npm run lint:frontmatter reports 0 errors for both files
• No other frontmatter or markdown lint regressions
