WHAT IT DOES

What set_week_theme does on Coach AI

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

RISK

Why set_week_theme is rated Medium

The tool appears to set a weekly theme for the productivity/coaching system, which is a reversible data modification. This fits the Write category—it creates or updates user preferences or goal structures, but is not destructive (reversible), not financial, not execute-level code running, and not read-only.

From the tool's definition Tool name 'set_week_theme' combined with sibling tools that modify state (add_todo, complete_todo, create_daily_note, add_task_context) indicates this creates or modifies user-facing goal/productivity data. No explicit description provided.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs set_week_theme safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Coach AI, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_week_theme, this is the rule to start with:

set_week_theme Rate-limited

set_week_theme stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
