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

No annotations are provided, so the description carries the full burden. It usefully discloses the return format (Markdown full text) and that only public pages are served, but says nothing about behavior on an invalid path, rate limits, or whether content is cached/static.

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: the first establishes what is returned, the second the prerequisite. No padding, and the core capability is front-loaded.

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 correctly states the return format (Markdown text), and it covers the path-acquisition prerequisite. It is nearly complete for a single-param read tool; only error/failure behavior is left unstated.

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 schema already gives a format example for `path`. The description adds only the constraint that the path must be valid and where to get one, which is helpful but not meaningfully beyond the schema.

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 (read/return), resource (one public page of pavels.dev), and output form (Markdown), and scopes it against the sibling list_* tools by requiring their paths. An agent can immediately tell this fetches a single page's content rather than enumerating content.

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?

Explicitly names the prerequisite: use list_services, list_case_studies or list_articles first to obtain a valid path. This is clear routing guidance, though it does not state when NOT to use it (e.g., for non-public or contact pages, which siblings cover).

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