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

With no annotations provided, the description carries the full burden of behavioral disclosure. While 'Update' implies a mutation operation, the description doesn't address critical behavioral aspects: whether this requires specific permissions, whether changes are reversible, what happens to unspecified fields (partial vs full updates), rate limits, or error conditions. For a mutation tool with 10 parameters and no 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 communicates the core functionality without any wasted words. It's appropriately sized for a tool with a clear purpose and doesn't bury important information. Every word earns its place by specifying what can be updated.

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 mutation tool with 10 parameters, no annotations, and no output schema, the description is incomplete. It doesn't address behavioral aspects (permissions, side effects), provide usage guidance, or explain what the tool returns. The 100% schema coverage helps with parameters, but the description fails to compensate for the lack of annotations and output schema, leaving significant gaps for the agent.

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?

The description lists the types of fields that can be updated ('name, note, limits, or expiration'), which provides high-level context beyond the schema. However, with 100% schema description coverage, the input schema already documents all 10 parameters thoroughly with descriptions, constraints, and enums. The description adds minimal additional semantic value beyond what's already in the structured schema.

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 action ('Update') and target ('existing provider') along with specific fields that can be modified ('name, note, limits, or expiration'). It distinguishes itself from sibling tools like 'create_provider' by specifying it updates existing providers rather than creating new ones. However, it doesn't explicitly differentiate from other update tools like 'update_rate_limit' or 'update_usage_limit' that might have overlapping functionality.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (like needing admin permissions), when not to use it, or how it relates to sibling tools like 'update_rate_limit' or 'update_usage_limit' that might handle similar settings. The agent must infer usage solely from the tool name and parameter schema.

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