verify_oidc_claims

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 discloses that the tool checks specific claims and detects missing required claims and mismatches, which are core behaviors. However, it does not explicitly state that it is read-only or describe error handling or side effects, which would be beneficial.

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 concise sentences. The first sentence states the purpose (validate OIDC claims), and the second adds specifics about what is checked and detected. No wasted words.

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?

With 4 parameters and no output schema, the description is partially complete. It explains the validation checks but lacks details on return format, error handling, and exact parameter behavior (e.g., what happens if expected_nonce is not provided). Adequate for basic understanding but leaves gaps.

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 0%, and the description does not explain individual parameters (token, expected_nonce, expected_issuer, expected_audience). It only mentions the claims checked (nonce, iss, aud) which obliquely relates to expected parameters but does not clarify their meaning or format.

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 it validates OIDC-specific claims per OpenID Connect Core 1.0, listing specific claims (iss, sub, aud, exp, iat, nonce) and detection of missing required claims and mismatches. This distinguishes it from sibling tools like decode_jwt or validate_jwt which are more generic.

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 implies usage for OIDC token validation but does not explicitly state when to use this tool versus alternatives (e.g., validate_jwt, oauth_introspect). No exclusions or context for when not to use it are provided.

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