list_projects

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

readOnlyHint=true already declares the safety profile, so the description's main contribution is 'accessible', which implies results are permission-filtered to what the caller can see. That is a genuine behavioral detail, but nothing is said about result ordering, pagination semantics, or what happens when the caller has no access.

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?

A single short sentence with zero waste and the core scope front-loaded. It is efficient rather than padded, though it borders on under-specified rather than genuinely concise.

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?

For a read-only list tool with full schema coverage and no output schema, the essentials are present. Missing is anything about how 'projects' relate to the repository tools in the sibling set, or what the returned collection shape/ordering is, which an agent would need to place results 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 100%, with name, limit, start, and permission all documented inline including defaults. The description adds no filter syntax or semantic nuance beyond that, so the baseline 3 applies.

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?

States a specific verb and resource — 'List accessible projects/workspaces' — so an agent knows this is a read/list operation over project entities. It stops short of differentiating from the near-neighbor list_repositories, leaving the project-vs-repo boundary to inference.

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?

No guidance on when to call this versus alternatives such as list_repositories, and no preconditions stated. The agent must infer usage purely from the tool name and the 'accessible' qualifier.

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