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

With no annotations, the description carries the full burden; it does add real behavioral context by noting the matching is deterministic and that it returns trust, safety and access metadata rather than performing the action. However, it never explains what the safety/access metadata means, whether the call has side effects, or how the binding/external-effect gates behave.

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 tight sentence with the core action and its returns front-loaded and zero 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?

For a five-parameter tool with no annotations, no output schema and 0% schema descriptions, the one-line description is too thin. It hints at returned metadata but leaves the gating flags and their effects unexplained, which is the exact context an agent needs to call this safely.

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 0% and the description explains none of the five parameters. The Arabic/English mention loosely maps to locale, but the safety-critical allow_binding_action and allow_external_effect flags, plus limit, are left entirely undefined. Low coverage demands compensation that isn't delivered.

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?

Clear verb+resource: it matches an Arabic/English intent to SAASH capabilities and returns trust/safety/access metadata. 'before invocation' implicitly positions it relative to saash_grow_invoke, but no sibling is named explicitly, so it stops short of full differentiation.

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?

'before invocation' implies this is a pre-flight step ahead of an actual capability call, but the description never states when to use it versus saash_gateway_discover or saash_grow_invoke, nor any exclusions or prerequisites.

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