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

Annotations cover safety (readOnlyHint=false, destructiveHint=false) and idempotency, but the description adds valuable behavioral detail: the publishing domain is resolved automatically, and specific ValueError conditions for invalid password/access-level combinations. It stops short of describing permissions or side effects on existing settings.

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?

The description is front-loaded with the core purpose and then efficiently details the access levels and error cases. Every sentence is informative, though the raises section could be slightly tightened without losing meaning.

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?

Given the existence of an output schema and rich annotations, the description covers the essential behavior: access level semantics, automatic domain resolution, and validation errors. It does not mention the need to check URI uniqueness via a sibling tool, but the schema already enforces uniqueness, so this is a minor gap.

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 description coverage is 100%, so the schema already documents all four parameters, including enum meanings and the uniqueness/format of uri. The description reiterates most of this (e.g., joina.chat/{uri}, password gate) without adding significant new parameter semantics, so the baseline of 3 is appropriate.

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?

The description states a specific verb (Configure) and resource (agent's access level and public URL) and explains the three access levels, making the tool's purpose clear. However, it does not explicitly differentiate itself from siblings like gnosari_update or gnosari_manage_link, which could be confused with access management.

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?

The access level descriptions imply when each mode is appropriate (PUBLIC for open links, PASSWORD_PROTECTED for a gate, PRIVATE for API/embed only), which provides implicit usage guidance. But there is no explicit statement of when to choose this tool over alternatives, no prerequisites, and no exclusions.

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