List Security Scheme Components

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

Annotations already mark it readOnly; the description adds the project-context requirement and the effect of includeUsageCounts. It does not disclose pagination/return shape, but for a read-only list tool the annotation coverage lowers the burden.

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?

Two tight sentences, front-loaded with the core action, with no filler. The parenthetical and prerequisit are placed economically.

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 simple read-only listing with a fully described schema, the description is sufficient: it defines the resource, the optional toggle, and a key prerequisite. Lacking an output schema, a hint of the return shape would be nice but is not critical.

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 covers all 3 parameters with descriptions (coverage 100%), so baseline is 3. Description reinforces includeUsageCounts and the spec-version concept but does not add much beyond the 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 names a precise verb ('List') and resource ('security schemes'), and clarifies the OpenAPI location ('components/securitySchemes'). This clearly distinguishes the bulk list operation from the singular sibling get_security_scheme_component.

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?

It gives clear context: list for a spec version, optionally with usage counts. It also surfaces a prerequisite ('Requires project context') but does not explicitly mention alternatives or when not to use it.

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