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

No annotations are provided, so the description carries full burden. It states this is an update operation, implying mutation, but doesn't disclose behavioral traits such as required permissions, whether changes are reversible, rate limits, or what happens to unspecified fields (e.g., partial updates). For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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, efficient sentence that front-loads the core purpose without unnecessary words. Every element ('update,' 'existing guardrail,' 'name, checks, or actions configuration') earns its place, making it appropriately sized and well-structured for quick comprehension.

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 tool's complexity (mutation with nested objects), lack of annotations, and no output schema, the description is incomplete. It doesn't explain return values, error handling, or behavioral nuances like partial updates. For a 4-parameter tool with rich nested structures, more context is needed to guide effective usage beyond the basic purpose.

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 description coverage is 100%, so the schema already documents all parameters (guardrail_id, name, checks, actions). The description adds minimal value by listing the updatable fields ('name, checks, or actions configuration'), which aligns with the schema but doesn't provide additional syntax, format, or usage details beyond what's in the structured data.

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 verb ('update') and resource ('existing guardrail'), specifying what fields can be modified ('name, checks, or actions configuration'). It distinguishes from sibling tools like 'create_guardrail' by focusing on updates, though it doesn't explicitly contrast with other update tools like 'update_config' or 'update_prompt'.

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 provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing guardrail ID), exclusions (e.g., partial vs. full updates), or sibling tools like 'get_guardrail' for retrieval or 'delete_guardrail' for removal. The description implies usage for modifications but lacks explicit context.

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