update_log_service

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

No annotations are provided, so the description must disclose behavioral traits. It identifies the tool as a WRITE OPERATION requiring user confirmation. However, it does not describe permissions, idempotency, side effects, return value, or error handling. This is adequate but not thorough.

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 concise with a clear warning and a single sentence stating the purpose. It includes a helpful link to documentation. Every piece of information earns its place, though the warning could be formatted more prominently.

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 no output schema and no annotations, the description is minimally complete for a write operation. It highlights the necessity of reading the schema file, which provides detailed structure, but the description itself lacks information about return values, error conditions, and exact behavior beyond the update action.

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?

All three parameters are fully described in the input schema (100% coverage). The tool description does not add new semantic information beyond the schema; it merely reiterates the requirement to read the schema file. With full schema coverage, baseline is 3.

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 'Updates information for an existing group-level logging service', specifying the verb 'updates' and the resource 'logging service'. This distinguishes it from sibling tools like add_log_service (create) and delete_log_service (delete).

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 includes a prominent warning 'WRITE OPERATION - Confirm with user before calling', providing a key usage guideline. It also implies when to use (updating existing) vs alternatives (add, delete) but does not explicitly state exclusions or comparative scenarios. The prerequisite to read the schema file is also a guideline.

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