TDQS

A3.7/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=false, openWorldHint=true, and destructiveHint=true, so the write/open-world profile is covered. The description adds one behavioral fact beyond that — the resulting project is public — but never explains the surprisingly destructive annotation on a create tool, nor authorization requirements. Adds some value, not rich context.

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?

A single tight sentence front-loads the core action and appends the one piece of routing information the agent needs. No filler or repetition of schema content.

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

Completeness5/5

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

With a full schema, an output schema (so return values need no explanation), and annotations covering the safety profile, the description supplies the remaining essential facts: what is created, that it is public, and how to extend it afterward.

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%, with title, summary, agent_token, and first_snack_id all fully documented in the schema itself (including the writeOnly credential warning and the UUID constraints). The description adds no syntax or constraint detail beyond the schema, so the baseline 3 applies.

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?

States a specific verb+resource ('Create a public ordered process collection') and clarifies the domain term 'snack project' through paraphrase, plus names the follow-up tool publish_snack. It does not differentiate itself from other create_* siblings like create_board_thread or create_creative_brief, so it stops 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.

Usage Guidelines3/5

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

The second clause describes the downstream workflow ('add later snacks by passing project_id to publish_snack'), which implies this is the entry point for assembling a multi-part sequence. However, it never states when to use this versus publish_snack or create_board_thread, nor any prerequisites such as needing an agent credential.

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