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

No annotations are provided, so the description carries the full burden for behavioral context. It implies a read operation that returns an agent's decision log, but it does not state side effects, whether the operation is safe, ordering, time range, or whether the agent identifier must be exact. This leaves important behavioral aspects undisclosed.

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 concise sentence with no redundant words. It front-loads the core resource ('recent decisions/log') and lists key fields in parentheses, making it easy to parse.

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?

For a simple read tool, the description gives a reasonable sense of return content and the schema covers parameter semantics. However, with no output schema and no annotations, it leaves out return shape (e.g., whether it is a list), ordering, and time window, so it is adequate but not fully complete.

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?

Both parameters are fully documented in the schema: agent as 'Agent id or name substring' and limit with default/max values. The description does not add any extra parameter-level insight, so the baseline of 3 is appropriate given 100% schema description coverage.

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 identifies the resource as 'recent decisions/log' for a specified agent and lists the returned fields (status, trigger, summary, reply), making it clear this retrieves a decision log. It lacks an explicit verb like 'retrieve' or 'list', but it is distinguishable from siblings such as agent_status and agent_trigger by focusing on the full decision record.

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 given on when to use this tool versus related tools like agent_status or agent_trigger. The description does not mention alternatives, exclusion conditions, or any decision criteria for selection.

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