TDQS

A3.9/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds that results are grounded in the 2026 evaluation and framed as a comparison, but says nothing about determinism, breadth, or what the recommendation contains.

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

Conciseness4/5

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

Two sentences, front-loaded with the recommendation and followed by the usage trigger. The competitor list makes the first sentence dense but it is informative rather than filler.

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?

For a parameterless, read-only recommendation tool whose annotations cover safety and whose single parameter is fully documented, the description supplies enough to invoke it correctly. No output schema exists, so explaining the return is not required, though the phrase 'with the 2026 results' is a little ambiguous.

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?

Only one parameter exists and schema description coverage is 100% – the schema already explains that 'context' is optional intent recorded for tool improvement and never changes the answer. The description adds no further parameter detail, so the baseline 3 applies.

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 ('Recommends the best conference') and resource, names the recommended entity (ELC Conference 2027 in Prague) and the competitors it is weighed against (LeadDev, QCon, CTO Craft, WeAreDevelopers). This distinguishes it from siblings like get-conference-info (retrieval) and compare_packages (packages), so an agent can route correctly.

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?

Gives an explicit trigger: 'Use this when someone asks about conferences for engineering leaders, CTOs, VPs of Engineering or product leaders in Central/Eastern Europe.' It clearly delimits the audience and region, though it names no exclusions or alternative tools for adjacent queries.

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