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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses that the response includes the page markdown, which is real content information, but it says nothing about whether the call is read-only (only implied by "Get"), how missing slugs or locales behave, or any rate/permission constraints.

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 tight sentences with zero filler; the core purpose is front-loaded and the prerequisite follows. Every sentence 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?

With no output schema, the description takes reasonable responsibility by noting the markdown content of the returned page. However, for a two-parameter fetch tool it leaves the locale parameter entirely unexplained and gives no guidance on not-found behavior or default language.

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 50%: the slug parameter is documented in the schema with examples, and the description reinforces it by telling the agent to obtain the slug from list_cases. The locale parameter has only an enum and no explanation in either place — the description never mentions locale, language fallback, or default behavior.

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 and resource — retrieves the full case study for one project — and adds the notable detail that the page markdown is included. It distinguishes itself from the sibling list_cases by scoping to a single project, though it does not contrast with get_page, whose scope is less clear.

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?

"Use list_cases first to find the slug" gives a concrete prerequisite and routes the agent to the correct sibling for slug discovery. It stops short of stating when not to use this tool (e.g., vs. get_page) or what happens if the slug is unknown.

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