get_article

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

readOnlyHint=true already establishes the safe-read profile, and the parenthetical adds genuinely useful context that the response carries full HTML content (volume/payload expectations). It stops short of permission needs, content-size caveats, or error behavior for missing IDs.

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?

One compact sentence, front-loaded with the action and resource, with the payload note in a parenthetical rather than padding. No wasted words.

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 annotation-backed safety and no output schema, the description covers action, identifier, and what comes back. Only a brief note on when to prefer it over list_articles would make it fully complete.

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% and the single 'id' parameter is documented in the schema as 'Article ID'. The description's 'by ID' simply echoes that; no format, type, or resolution details are added.

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?

Specific verb+resource: retrieves a single article by ID, and clarifies the payload includes full HTML. It is easily distinguished from list_articles/create_article/update_article by name, but the description itself does not name those siblings or contrast scope.

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 on when to use this versus list_articles or search alternatives, no prerequisites, and no exclusions. The agent must infer that this is the single-record fetch 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.
