TDQS

C2.2/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false and destructiveHint=false, so the safety profile is largely covered. The description adds one genuinely useful behavioral fact — the twin becomes visible on a *shared* globe, i.e. public exposure — but says nothing about the truncated remainder, rate limits, moderation, or what happens on resubmission despite idempotentHint=false.

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

Conciseness2/5

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

A single sentence is appropriately short, but it terminates mid-word-boundary at 'at...', so the definition is literally incomplete and the most informative part (presumably a URL or destination) is lost. Front-loading is fine; the truncation is the problem.

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

Completeness1/5

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

A six-parameter mutation tool with no output schema, 0% schema coverage, and a truncated description leaves the agent unable to construct a valid call. Nothing explains manifest format, what proof/key must contain, or whether 'dry' performs validation only — a critical gap for a non-idempotent write.

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

Parameters1/5

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

Schema description coverage is 0% and the description explains none of the six parameters. The especially opaque ones — 'manifest' (the only required field, accepting object or string), 'proof', 'key', 'entry_js' vs 'entry_url', and 'dry' — get no explanation at all, so the agent must guess at authentication and validation semantics.

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

Purpose3/5

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

The verb 'Put' plus 'your own digital twin' with examples (factory, line, building, lesson) conveys a publish/register action, and 'on the shared 3D globe' implies publication to a shared space. But the sentence is truncated mid-clause ('at...'), so the actual statement of what gets created or where is cut off, leaving the purpose only partially resolved.

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

Usage Guidelines2/5

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

There is no guidance on when to use this versus twin_get, twins_community, twins_search, twins_near, or site_publish/app_publish. Nothing states prerequisites (an account, an agent identity, a signed proof) or whether a prior twin_get is needed before submitting.

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