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

With no annotations provided, the description carries the full burden. It discloses the validation step, the output structure, and a rate limit, but it does not clarify whether the tool creates a persistent session or how it handles invalid codes. This is a moderate disclosure.

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 a single, compact sentence that front-loads the action and specifies the output components. No redundant information is present; every word adds value.

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?

For a tool with one parameter and no output schema, the description covers the input's purpose and outlines the output's composition. It lacks explicit error handling and side-effect transparency, but the core workflow is adequately described.

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?

The schema only defines 'code' as a string, but the description explains it is a 'Polish poetry session code' and that it is validated. This adds essential semantic context beyond the raw schema, which is necessary given 0% schema coverage.

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 names a specific action sequence: validate the session code, then emit a full team briefing with enumerated components (guardian, style, personas, skills, persist block). This clearly distinguishes it from the sibling tools, which are mostly list/get/read/write operations.

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 description implies the tool is used for bootstrapping a Polish poetry session but does not explicitly state when to use it or mention alternatives. The rate limit adds operational context, but there is no when-not or exclusion guidance.

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