update_author_notes

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

With no annotations, the description carries the full burden. It indicates a write operation but leaves out details about potential side effects, required permissions, or whether updates are incremental or full replacements. This lack of disclosure limits an agent's understanding of behavioral consequences.

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?

The description is relatively concise and structured with an Args section. The lead sentence immediately conveys the tool's purpose. Minor verbosity from the Args formatting does not detract significantly.

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?

Given the simple parameter set and no output schema, the description covers the essential inputs. However, it omits details about behavior such as whether updates are additive or whether non-existent authors are created, leaving some contextual gaps.

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?

The description compensates for the 0% schema coverage by explaining each parameter in detail, especially 'style_notes' with its expected dictionary keys (prose, themes, strengths, comparable_to). This adds significant meaning beyond the raw schema types.

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?

The description clearly states the tool updates notes about an author's style and impressions. It specifies the resource (author notes) and the action (update). However, it doesn't differentiate from siblings like 'save_reflection' or 'get_author_profile', though the purpose is specific enough.

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 is provided on when to use this tool versus alternatives such as 'save_reflection' or 'get_author_profile'. The description merely explains what the tool does without contextual usage tips.

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