TDQS

A3.6/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and non-destructive behavior. The description adds that responses are summarised and cited from a curated knowledge base, but it does not add further behavioral context such as rate limits, freshness, or limitations. With annotations covering the safety profile, a 3 is appropriate.

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?

Two sentences, front-loaded with the tool's purpose and domain scope, followed by the return behavior. No wasted language and easy for an agent to parse.

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

Completeness4/5

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

The description covers purpose, domain, and return nature, while annotations cover safety and the schema fully documents parameters. No output schema exists, but the description sufficiently indicates that callers receive summarised, cited insights. Minor missing context around result freshness or limitations keeps it at 4.

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 every parameter including email tier behavior, top_k range, and subscribe semantics is already documented in the schema. The description does not add meaning beyond the structured fields, making the baseline 3 appropriate.

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

Purpose4/5

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

The description names a specific specialist and domain topics (SaaS metrics, cash flow, valuation, fundraising, CFO topics), and states the return format as summarised, cited insights. It clearly separates this finance-focused tool from generic siblings, though it does not explicitly contrast with any specific sibling tool.

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

Usage Guidelines3/5

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

Usage is implied by the domain scope: ask this specialist for finance topics. There is no explicit guidance on when to prefer this over ergora_business_strategy or ergora_ask, and no exclusions or prerequisite context beyond what the schema states.

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