check_budget

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

With no annotations provided, description carries full behavioral disclosure burden. Excellent coverage: specifies reset schedule ('resets on schedule'), calculation logic ('clamped to >= 0'), rate limiting enforcement status, and precise return structure including ISO 8601 timestamp format.

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?

Well-structured with clear visual separation between purpose statement and return value specification. Front-loaded with the core action. Detailed return dictionary is verbose but justified given budget monitoring requires precise field definitions.

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?

Comprehensive coverage for a zero-parameter read operation. Despite existence of output schema (per context signals), description ensures completeness by documenting all return fields, calculations, and temporal behaviors (reset schedules) that might not be visible in schema alone.

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?

Zero parameters present; baseline score of 4 applies per rubric. Description appropriately does not fabricate parameter semantics where none exist.

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?

Clear verb ('Check') and resource ('safety budget utilization'). Implies read-only status check distinct from sibling 'certify_action' (which performs mutations) by framing itself as state retrieval and referencing certifications as metadata rather than actions.

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 explicit when-to-use guidance or comparison to siblings. Does not advise calling this before 'certify_action' to validate budget availability, though the return structure implies this use case.

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