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

With no annotations, the description carries the full behavioral burden. It usefully discloses returned fields and that private projects appear only as hidden:true, but it does not mention permissions, pagination, ordering, or other list behavior.

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 a single front-loaded sentence that lists the relevant return content and privacy behavior. Every part contributes information without repetition or filler.

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 a fairly rich schema with documented enum/default parameters and no output schema, the description supplies the key purpose, return fields, and private-project behavior. The main remaining gap is that it does not route the agent against sibling tools, but that is primarily a usage-guideline concern.

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 80%, so most parameters are already documented in the schema. The description adds no parameter-specific meaning, and the required handle parameter lacks a schema description, leaving its semantics only implicitly covered by 'A profile's projects'.

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 identifies the resource as a profile's projects and lists the fields returned, including open-source contributions. It is distinguishable from the singular get_project sibling, but it does not explicitly state a verb like 'list' or directly name an alternative.

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 gives no guidance on when to use this tool versus alternatives such as get_project, get_profile, or search. It implies usage by describing the returned data, but does not state any conditions, exclusions, or sibling routing.

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