get_pending_observations

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It states that the tool retrieves observations but does not explicitly state it is read-only, describe the return format, pagination, or any side effects. The description's sole behavioral hint is 'periodic call', implying safety, but this is insufficient without annotation backing.

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 concise—two short sentences that state the purpose and usage frequency. It avoids unnecessary fluff and gets to the point quickly. While it lacks structured sections, the brevity is appropriate for a simple retrieval tool.

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?

The description is incomplete given the absence of annotations, output schema, and parameter descriptions. It does not specify what the returned data looks like, how to handle multiple pages of observations, or any limits beyond the schema default. An agent would struggle to correctly process results or know how to use the 'limit' parameter effectively.

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 completely ignores the only parameter 'limit' (with default 20). It does not explain what 'limit' controls (e.g., maximum number of returned items) or how to use it. The description adds no value beyond the schema's bare parameter definition.

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 retrieves observation records pending reflection ('获取所有待反思的观察记录'). It is specific about the resource and its state ('pending reflection'), and the verb 'get' is clear. While it doesn't explicitly contrast with sibling tools like record_observation or reflect_and_save, the purpose is evident and distinct 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?

The description advises calling periodically ('定期调用') to check for unprocessed errors needing reflection, giving a clear usage scenario. However, it provides no guidance on when not to use it or mentions alternatives, such as other observation-related tools. The usage context is implied but lacks exclusions or comparative guidance.

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