reopen_comment · Codecks MCP: Risk & Policy

WHAT IT DOES

What reopen_comment does on Codecks

AI agents use reopen_comment to create or update resources in Codecks — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Codecks environment.

WHY IT NEEDS A POLICY

Why reopen_comment needs a policy

This tool modifies existing data (comment state) in a reversible manner. Reopening a comment does not delete or destroy data, and does not execute arbitrary code or affect finances. It falls under Write category as it changes the state of a comment thread.

From the tool's definition Tool name 'reopen_comment' and description 'Reopen a closed comment thread' indicate a state modification operation. This reverses a prior close action on a comment, modifying the comment's status from closed to reopened.
