apply_subtopic_assignments

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

The description implies a write operation but does not disclose potential side effects, such as overwriting existing frontmatter, or permission requirements. With no annotations, the agent has minimal behavioral context.

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 too brief for a tool with two parameters and nested objects. It sacrifices necessary detail, making it insufficiently informative for correct usage.

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?

Despite having an output schema and nested parameters, the description omits crucial context like output format, behavior on existing data, error handling, and usage workflow. It fails to provide a complete picture.

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%, and the description does not explain the parameters 'cluster_slug' or 'assignments'. The agent cannot infer their meaning or structure, especially with a nested object type.

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 action (write) and target (subtopics frontmatter to each paper note). It distinguishes from sibling tools like 'propose_subtopics' which generates subtopics, but could be more explicit about the context of cluster usage.

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 on when to use this tool versus alternatives like 'propose_subtopics' or 'apply_cluster_summaries'. The description lacks any context or prerequisites.

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