list_registry_projects_for_ga4

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description must carry behavioral info. It mentions conditions (env set) and hints, but does not disclose failure modes, pagination, or ordering. Since it's a read list, it's adequate but not detailed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no wasted words. Highly concise and front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given low complexity and output schema existence, description lacks clarity on what 'with .ga4.config.json and .keymaster hints' means for the output, and how filter_query interacts. Adequate but leaves gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%. Parameters 'limit' and 'filter_query' are not explained in the description. While names are suggestive, the description does not clarify what filter_query applies to (e.g., project names). No compensation for low schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states verb 'list', resource 'launcher registry projects', and conditions about config files and keymaster hints and env variable. It distinguishes from sibling tools like create/get/provision by focusing on listing with specific hints.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Description implies usage when registry env is set, but does not explicitly state when not to use or compare with alternatives like resolve_project_for_ga4. No exclusion criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
