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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed-world scope, so the safety profile is fully covered. The description adds two useful facts beyond that: the note belongs to the user (ownership scoping) and the result is the full text rather than metadata. It says nothing about error behavior for a missing id, but the safety and return-shape burden is largely carried elsewhere.

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 sentence, front-loaded with the verb and resource, with no redundant restatement of the title or annotations. Every clause ('full text', 'one of the user's', 'by id') carries distinct information.

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 one required parameter, full schema coverage, a present output schema, and rich annotations, the definition covers what an agent needs to invoke it correctly. The only residual gap is the absence of any statement about failure when the id does not exist.

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 there is a single required 'id' parameter already documented in the schema, so the baseline is 3. The description's phrase 'by id' confirms the id identifies a specific note but adds no format, source, or provenance detail 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+resource pair ('Fetch the full text of ... literature notes') and scopes it to a single note identified by id, which implicitly distinguishes it from list_recent_literature_notes and search_literature_notes. It stops short of naming those siblings explicitly, so an agent must infer the boundary from 'by id'.

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?

Usage is implied rather than stated: the 'by id' phrasing signals this is the retrieval step once an id is known, and the sibling names (list_/search_/count_literature_notes) make the alternative paths inferable. There is no explicit when-to-use or when-not guidance, and no note about what happens if the id is unknown.

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