Design status

design_status
Read-onlyIdempotent

Check whether a session started with design_session is ready. While generating it returns a wait instruction; when ready it returns the BRANDED HTML SESSION BRIEF — render it as an artifact. Free (no credits).

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

    "arguments": {
      "session_id": "<session_id>"
    },

TDQS

A4.5/5.0
Behavior5/5

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

Beyond the readOnly/idempotent annotations, the description discloses both possible return states (wait instruction while generating, HTML brief when ready), an action the caller must take on the result (render as an artifact), and the cost profile (free, no credits). This is exactly the behavioral context annotations cannot convey.

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 with zero waste, front-loading the core check and then the two outcome states plus the free-cost note. Every sentence earns its place.

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?

No output schema exists, yet the description covers both possible responses and what to do with the successful one, so an agent has everything needed to call and handle this polling tool correctly.

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 coverage is 100% and the single parameter is already documented as 'The session id design_session returned.' The description adds no format, sourcing or validation detail beyond what the schema provides, 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 and resource ('Check whether a session started with design_session is ready'), and explicitly ties the tool to its sibling design_session so the agent can distinguish the polling tool from the session-creation tool without opening schemas.

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?

Makes the usage context clear: it is the follow-up poll to design_session, and the 'while generating it returns a wait instruction' phrasing implies it should be re-called until ready. No explicit when-not or alternative routing is given, so it stops short of a 5.

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