system_get_x25519_keypairs

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

No annotations are provided, so the description carries the full burden. It does not disclose whether the operation is read-only or mutating, whether it persists generated keys, whether it consumes system resources, or whether it is safe to call repeatedly. Listing the HTTP method (GET) hints at read semantics but is not a reliable behavioral guarantee.

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 short but is largely a restatement of the HTTP endpoint and tag metadata rather than an explanation of the tool's purpose. It is not bloated, but the front-loaded sentence does little beyond stating the obvious action.

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 tool with no annotations, no output schema, and zero parameters, the description should at least explain what the generated X25519 keypairs are for, whether they are returned or stored, and whether the operation has side effects. None of this is covered.

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?

Parameter count is 0, and the schema has no properties. Per the scoring guide, 0 params yields a baseline of 4. The description adds no parameter detail because there are none, which is appropriate.

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 states a specific action (generate 30 X25519 keypairs) and includes the HTTP route GET /api/system/tools/x25519/generate and a tag. The purpose is understandable, but it does not differentiate from the only similar sibling keygen_generate_key, nor explain what kind of keypairs or their use.

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 or why to use this tool versus alternatives such as keygen_generate_key or other system_* tools. The agent is left to infer usage context entirely.

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