generate_daily_summary

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

With no annotations, the description must disclose all behavioral traits. It mentions LLM usage and aggregation of session events, but does not state whether the tool is read-only, destructive, or if it has side effects like caching. The cost of calling an LLM and potential dependencies are not addressed.

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 a single sentence with clear front-loading. However, the phrase 'with pet reaction' adds some ambiguity and could be considered extraneous. Overall it is concise but not maximally efficient.

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 lacks details about the output format (only 'natural language summary'), does not mention caching behavior, and does not specify prerequisites like existence of session events. Given the absence of an output schema, more context is needed.

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% with both parameters described in detail. The description adds no additional meaning to the parameters, but baseline 3 is appropriate as the schema already provides sufficient semantics.

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 that the tool generates an LLM-powered daily coding summary with a pet reaction, specifying the verb 'Generate' and the resource 'daily coding summary'. This is distinct from sibling tools which focus on fixing, diagnostics, or retrieving content.

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. It does not mention that it uses cached summaries by default or that it should be called after session events are collected. No exclusions or alternative tool references are given.

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