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

With no annotations provided, the description carries full burden for behavioral disclosure. It states the tool lists projects with optional filtering, but doesn't describe important behaviors like pagination, rate limits, authentication requirements, sorting order, or what 'all projects' means in practice (e.g., archived projects included?). For a list operation with zero annotation coverage, this leaves significant gaps in understanding how the tool behaves.

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 perfectly concise with two clear sentences: one stating the core purpose and one explaining the optional parameter. Every word earns its place, and the information is front-loaded with the primary function stated first. No wasted words or unnecessary elaboration.

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 the tool's moderate complexity (list operation with filtering), no annotations, and no output schema, the description is minimally adequate but incomplete. It covers what the tool does and the parameter purpose, but lacks behavioral context (pagination, permissions, etc.) and output format information. For a tool with 1 parameter and 100% schema coverage, it meets basic needs but leaves important operational questions unanswered.

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 100%, so the schema already fully documents the single optional 'query' parameter. The description adds that the query filters by 'project name or key', which slightly elaborates beyond the schema's 'filter projects by name or key'. However, this is minimal additional value since the schema already provides the essential information.

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 ('List all projects') and resource ('in the organization'), making the purpose immediately understandable. It distinguishes from siblings like 'get_project' (singular retrieval) and 'create_project' (creation), though it doesn't explicitly name these alternatives. The description is specific but could be more precise about sibling differentiation.

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 implies usage for listing projects with optional filtering, but provides no explicit guidance on when to use this tool versus alternatives like 'get_project' for single project retrieval or 'create_project' for creation. It mentions filtering capability but doesn't specify scenarios where filtering is appropriate versus retrieving all projects.

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