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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Read', implying a safe read operation, but adds no details about return format, potential errors, authentication requirements, or side effects. For a tool with zero annotation coverage, this is a significant gap.

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, focused sentence with no wasted words. The key information ('Read one section... by id') is front-loaded, and the sentence is appropriately sized for the tool's simplicity.

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 simple read tool with one parameter and no annotations, the description covers the core purpose but misses return value expectations (e.g., what content is returned, whether it is plain text or structured). Since there is no output schema, the description could be more complete by stating what the agent receives, but the simplicity of the operation makes it adequate for basic selection.

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 parameter 'id' is already documented as 'Section id, e.g. m001'. The description's 'by id' adds no new meaning beyond what the schema provides. Baseline score of 3 applies because the schema fully covers parameter semantics.

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 ('Read') and a specific resource ('one section of Mar00n Book 1') with a clear parameter ('by id'). It distinguishes itself from siblings like read_maroon_manifest and read_briefing by explicitly naming 'section' and 'Book 1', which are not ambiguous with the other read tools.

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?

There is no guidance on when to use this tool versus siblings. It does not mention alternatives, prerequisites, or conditions under which the tool is appropriate. The description merely states the action, leaving the agent to infer usage context from the name alone.

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