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

Annotations already declare read-only and idempotent behavior, so the description only needs to add extra context. It adds 'App-only' and 'session-scoped' constraints, which are useful, but 'hydrate' remains vague about whether the tool returns data, initializes the board, or both.

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 sentence with no wasted words, but it is arguably too terse. The term 'hydrate' could be replaced with more explicit language, yet the structure is clean and front-loaded.

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 must convey what the agent should expect. It does not explain what a 'Shoot Board' is or what 'hydrate' returns or does, leaving significant ambiguity about the tool's actual effect and return value.

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 tool has zero parameters, so there is no parameter documentation burden. The baseline of 4 applies since the description doesn't need to compensate for schema gaps.

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 title 'Get Shoot Board' clarifies the retrieval intent, and the description identifies the resource ('Uwear Shoot Board') and scope ('session-scoped'). The verb 'hydrate' is somewhat non-standard but still conveys loading the board. It is distinguishable from mutation siblings like mcp_add_context, though 'hydrate' adds jargon.

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?

No guidance is given on when to use this tool vs alternatives such as request_user_context or other getters. The 'App-only' label is a constraint, not a usage trigger, and no exclusions or alternative tools are mentioned.

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