Why link_commits_to_sessions needs a policy

The tool appears to read git commit history and writing session data, then correlates them for contextual analysis. 'Linking' here likely means creating an association or mapping in memory/display rather than writing persistent data. However, if it writes this linkage to a file or database, it would be Write. The description is vague, so confidence is moderate.

From the tool's definition 'Link git commits to writing sessions for context' — associates/correlates existing data for analytical context

How to control link_commits_to_sessions

PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Writer's Aid MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for link_commits_to_sessions:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "link_commits_to_sessions": {}
  }
}

link_commits_to_sessions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
