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

With no annotations, the description must carry the behavioral burden. It does disclose one real trait — results are scoped to the token's access rights — and hints the payload contains project ids, but it says nothing about ordering, pagination, or whether names/other fields are returned.

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?

Two short sentences, no filler, with the scope constraint front-loaded before the usage hint. Every clause earns its place.

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 zero-parameter read tool with no output schema, the description covers what it returns at a high level (projects, and specifically the id) and why an agent would call it. The exact shape of each returned record is the only material gap.

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?

The tool takes zero parameters, so the baseline is 4; there is nothing the description could usefully add on that axis. The mention of the project id in the output is a small bonus beyond what an empty schema conveys.

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 the QA projects") plus a scope qualifier ("this token can access"). No sibling tool (get_exploration, list_issues, get_test_run, etc.) lists projects, so the tool is distinguishable without naming an alternative, though the description doesn't say so explicitly.

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?

"Use it to find the project id the other tools need" gives a concrete entry-point condition: call this first to obtain a prerequisite id. It doesn't state any when-not-to-use case (e.g., if the project id is already known), but the usage context is clear.

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