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

Annotations already declare this tool safe (readOnlyHint=true, idempotentHint=true, destructiveHint=false). The description adds useful behavioral context beyond annotations by stating it retrieves the page 'in full' and by identifying the source and license (blender.org, CC-BY-SA 4.0), which is relevant for reuse.

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?

A single concise sentence contains the verb, resource, scope, and path source, followed by licensing information. No filler or redundancy; every phrase earns its place.

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 one-parameter, read-only tool with a rich output schema and complete annotations, the description fully covers what an agent needs: what it fetches, how to identify the resource, and the license terms. Nothing essential is missing.

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%, with the path parameter already documented as 'Manual page path returned by docs_manual_search.' The description reinforces this but adds no new semantic detail beyond what the schema provides. 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 ('Fetch'), a precise resource ('one Blender manual page in full'), and the required mechanism ('by its path'). It also references docs_manual_search, which distinguishes it from sibling docs tools like docs_bpy_search and docs_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 clearly implies the intended workflow: first use docs_manual_search to obtain a path, then call this tool with that path. It provides clear context but does not explicitly name alternatives or state when not to use it. No exclusions are given.

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