  9. First observed

TDQS

A3.9/5.0
Behavior3/5

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

With no annotations, the description carries the full burden, and it does disclose the required auth scheme ('Authorization: Bearer ppn_live_*'), which is genuinely useful. However, it says nothing about the fact that arbitrary operations (including destructive writes via POST/PUT/PATCH) can be issued against 60 APIs, nor about error handling, rate limits, or side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, zero filler, and the most important operational facts (what it does, the search_apis prerequisite, the auth requirement) are front-loaded in that order.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a generic multi-API executor with no annotations and no output schema, the description covers the calling workflow and auth but omits mutation semantics, response shape, and failure behavior. Adequate to invoke correctly, but thin given the tool's broad and potentially destructive surface.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents api, operationId, body, and params, establishing a baseline of 3. The description reinforces the provenance of api/operationId (from search_apis results) but adds no syntax or format detail beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (execute) and resource (a request against one of 60 registered APIs), and scopes it precisely enough that it is immediately distinguishable from the sibling search_apis, which the description explicitly frames as a lookup step rather than a substitute.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly tells the agent to call search_apis first to obtain the correct api name and operationId, which is the exact prerequisite workflow needed. It stops short of stating when NOT to use this tool (e.g., for read-only discovery or environment inspection via environment_brief).

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