get_bedrock_daily_usage_stats

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

No annotations provided, so description must carry full burden. It only states 'Get' and returns a string, but does not disclose read-only nature, required permissions, rate limits, or any side effects. Insufficient for a data retrieval tool.

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?

Description is very brief with structured Args/Returns. Front-loaded with purpose. However, it sacrifices clarity for brevity by omitting important details.

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?

No output schema, so description must describe return value – it does as 'formatted string'. But nested parameter object is not explained, and sibling differentiation missing. Incomplete for a parameterized tool with no annotations.

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 0% meaning description does not explain parameters. It vaguely mentions 'number of days and region' but omits log_group_name, defaults, and constraints. Schema itself has descriptions, but tool description adds no value.

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?

Description clearly states 'Get daily usage statistics with detailed breakdowns', specifying verb and resource. It distinguishes from hourly stats and EC2 spend siblings through 'daily' in name and description.

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 siblings like get_bedrock_hourly_usage_stats or get_detailed_breakdown_by_day. Agent has no context on selection criteria.

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