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

With no annotations, the description carries the full behavioral burden. It does disclose that capability-token and ownership checks occur before execution, which is valuable, but it does not explain what happens on failure, whether execution is sandboxed, what side effects occur, or what the response contains. This is thinner than needed for an unannotated mutation/proxy tool.

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 compact, front-loaded sentence with no filler. However, it is under-specified for a generic proxy tool and provides no structure such as expected usage patterns or parameter roles, so conciseness edges toward incompleteness rather than efficiency.

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?

This is a complex generic tool with four parameters, a nested arguments object, no output schema, and no annotations. The description explains neither how to construct arguments, what 'tool' should contain, what the return value looks like, nor how failures surface. An agent would not have enough information to call this tool 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 0%, so the description must compensate, but it only loosely hints at capability_token and run_id through the phrases 'capability-token and ownership checks' and 'for this run.' The 'tool' and especially 'arguments' parameters are left unexplained, and the nested object structure receives no guidance at all.

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 names a specific action ('Proxy an approved project executor tool') and a resource ('for this run'), making the core purpose clear beyond the tool name. It does not explicitly differentiate from sibling project_* and gateway_* tools, so it falls short of a 5.

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 gateway versus direct executor tools like project_read_file, project_write_file, or gateway_run_status. It implies a proxy role but provides no exclusions, alternatives, or preconditions beyond the mention of capability-token and ownership checks.

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