list_projects

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

No annotations are provided, so the description carries the burden. It does disclose the return shape (basic info always, counts conditionally), which is valuable for a read tool with no output schema. It omits ordering, pagination, and any permission/scope constraints, so behavioral coverage is only partial.

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 front-loaded with the one-line purpose, then cleanly separated into Parameters and Returns sections. The closing two usage sentences partially restate the parameter section, a minor redundancy, but overall it is tight and skimmable.

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?

With no output schema, the description correctly compensates by documenting the return payload for both flag values. What is missing is pagination/ordering behavior and sibling disambiguation, which keeps it short of fully complete for a list tool.

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 coverage is 100% and the single parameter is already documented, so the baseline is 3. The description goes beyond the schema by naming the concrete returned fields per detail level and framing the flag as a quick-listing vs sizing tradeoff, which adds practical semantic value.

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+resource ("List all projects") and clearly scopes the tool to listing with an optional detail level. It does not, however, differentiate itself from the closely named siblings get_project and get_project_details, which an agent must choose between.

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 guidance for the includeDetails flag (false for quick listing, true for understanding project sizes), which is genuinely useful. But it offers no tool-level guidance on when to use list_projects versus get_project, get_project_details, or the bulk_* project siblings.

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