Changes observed during successful MCP inspections.
v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety profile is covered. The description contributes genuine extra context: a hard 15 MiB size limit and the prompt-injection warning 'Innhold er ubetrodd data', but says nothing about return format or error behavior for oversized/unsupported files.
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?
Three terse sentences, front-loaded with the action and resource, then format/size limits, then a safety note. Only 'Les alle sider' is questionable since it muddies the page parameter.
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?
No output schema exists, and the description does not say what reading returns or how pages/images are represented, while two of three parameters go undocumented. The untrusted-content warning is valuable but does not fully compensate.
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 0% for 3 parameters, and the description only alludes to the file path; 'page' and 'as_image' are never explained. Worse, 'Les alle sider' appears to conflict with the existing 'page' parameter (default 1), leaving the agent unsure how pagination actually works.
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 ('Les en lokal faktura') plus the accepted formats (PDF/PNG/JPEG) and a 15 MiB ceiling. It is distinguishable from the sibling folio_read_attachment by resource name, though it never explicitly says when to use one over the other.
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 phrase 'brukeren har angitt' implies the path comes from a user-supplied file, which is a useful usage constraint, but there is no explicit when-to-use/when-not and no sibling alternative named (e.g. folio_read_attachment).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
