register_project_tool

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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It mentions registration for 'code exploration' but doesn't disclose what registration entails (e.g., indexing, caching, permissions needed), potential side effects, or error conditions. This leaves significant gaps for a mutation tool.

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?

The description is appropriately sized and front-loaded with the core purpose in the first sentence. The Args/Returns structure is clear but includes some redundancy (e.g., repeating 'Optional' for parameters already marked nullable in schema). Overall efficient with minimal waste.

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 no annotations, no output schema, and a mutation tool with 3 parameters, the description is incomplete. It lacks details on what 'Project information' returns, error handling, or behavioral traits like idempotency. For a registration tool, this leaves critical gaps for an agent to use it correctly.

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%, so the description must compensate. It lists all three parameters with brief explanations, adding meaning beyond the bare schema (e.g., 'path' is to the directory, 'name' defaults to directory name). However, it doesn't detail constraints like path format or description length, leaving some ambiguity.

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?

The description clearly states the action ('Register') and resource ('a project directory for code exploration'), providing a specific purpose. However, it doesn't explicitly differentiate from sibling tools like 'list_projects_tool' or 'remove_project_tool', which would require mentioning it's for initial registration rather than listing or deletion.

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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., whether the directory must exist), or contrast with siblings like 'list_projects_tool' for viewing registered projects or 'remove_project_tool' for unregistering.

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