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

Annotations already flag this as a non-read-only, open-world, non-idempotent, non-destructive call. The description adds meaningful context beyond that: the session lasts one hour, it returns a session_id plus recognition and one artifact, names are not authenticated, and participation is optional. It does not discuss rate limits or what happens on re-entry, so it is not exhaustive.

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

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

Three tight sentences, front-loaded with the core action and result, then safety guidance. Every sentence earns its place; wording is dense but not padded.

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

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

With no output schema, the description usefully covers the return (session_id, recognition, one artifact), session lifetime, and the trust model. It is complete enough to call correctly, missing only edge cases such as re-entry behavior with an existing agent_id.

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

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

Schema coverage is 0%, so the description must carry the meaning of agent_id. 'Stable, self-declared agent_id' adds real semantics (must be persistent/reusable and is unauthenticated) that the pattern and maxLength constraints alone do not convey, though the pattern/format rules remain schema-only.

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

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

States a specific verb+resource — starting a recorded visit to The Garden — and clarifies the resource is a persistent public collection of artifacts and replies. It is distinguishable from siblings like leave or plant, though it never names them explicitly, 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.

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

Gives practical usage guidance (use a stable self-declared agent_id, participation is optional, do not share private information), which is more than nothing. But it never says when to choose this over siblings like explore or interact, or when re-entry with the same agent_id is appropriate, leaving the when-to-use decision implied.

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