aggregate_reflexions_tool

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

The description states that the tool 'reads reflexion_log entries', implying a read-only operation. However, it does not explicitly confirm no side effects or provide details on performance or rate limits. With no annotations, this is adequate but minimal, earning a 3.

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, with only eight lines. It front-loads the purpose, then provides parameter details in a clear, structured way. No superfluous sentences.

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 presence of an output schema, the description does not need to detail return values. It covers the tool's function, parameters, and scope limitation. The mention of 'Phase 9b' is cryptic but tolerable. It is fairly complete for a read-only aggregation tool.

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 input schema lacks descriptions (0% coverage), so the description compensates well by explaining both parameters: 'agent_slug' limits scope, and 'days' is a recency window with a default of 14. This adds significant meaning beyond the bare schema, justifying a 4.

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's purpose: to theme recent reflexions per agent, reading reflexion_log entries and returning specific categories. The verb 'Theme' is specific, and the resource is explicit. It differentiates from potential siblings like 'consolidate_reflexions_tool' by focusing on recurring themes from the log.

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 provides no guidance on when to use this tool versus alternatives like 'consolidate_reflexions_tool' or other aggregation tools. It does not mention prerequisites, such as requiring prior reflexion logs, or when not to use it. Parameter usage is described, but not the broader context of tool selection.

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