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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint false, and openWorldHint false, so safety is covered. The description adds practical behavioral context: cursor pagination, the pageInfo shape, and passing endCursor back as cursor for the next page. It does not add auth or rate-limit behavior, but those are not needed here.

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 three tightly written sentences with no filler, and it front-loads the core action and scope before moving to usage and pagination mechanics. Every sentence contributes to selecting or invoking the tool correctly.

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 rich annotations, 100% schema coverage, and an available output schema, the description is complete for an agent to call the tool correctly. It covers purpose, usage contexts, pagination mechanics, and return summary without redundantly re-documenting every schema field.

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 baseline is 3 even without parameter detail in the description. The description mentions filtering, sorting, and pagination generally, and explains passing endCursor back as cursor, but that is already documented in the schema's cursor description. It adds little parameter meaning beyond the schema.

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 states a specific verb and resource: list the organization's projects with filtering, sorting, and cursor pagination. It also names use cases for discovery, disambiguation, and resolving a named project, which helps separate it from focused siblings like project_overview or project_stats. It does not, however, explicitly name a sibling alternative or contrast itself against one.

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?

It gives clear when-to-use guidance: discover/disambiguate projects, resolve a project the user named, or page through a large set. That is useful context for an agent choosing among many project-related tools. It stops short of explicitly stating when not to use it or naming a sibling alternative.

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