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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds useful value beyond that by disclosing what is returned ('the full Markdown') and that the path must originate from the sibling tools, which is non-obvious workflow context.

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?

Two sentences, both front-loaded with the operation and then the usage condition. No redundant restatement of the tool name or schema details.

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 single-parameter read tool with annotations covering safety and no output schema, the definition gives enough to call it correctly: what is fetched, the key, and when to prefer it. Return structure beyond 'full Markdown' is not elaborated, but that is not required here.

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 coverage is 100% and the path parameter already documents accepted formats ('.md' suffix, leading slash, full URL), so the description need not compensate. It only restates 'by its path' without adding syntax meaning, so the baseline 3 applies.

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?

States a specific verb+resource ('Fetch the full Markdown of one Griddo backoffice documentation page') with an explicit retrieval key ('by its path'). It also distinguishes itself from siblings search_griddo_editor_docs and list_griddo_editor_docs by naming them as the sources of the path.

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?

Gives a clear selection condition: 'Use it when the search excerpt is not enough to answer accurately,' which implicitly routes discovery to the sibling search/list tools. It names the alternatives but does not state an explicit when-not (e.g. don't use this for browsing or listing pages).

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