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

No annotations exist, so the description must disclose behavioral traits. It does not state whether the tool is read-only, what happens on invalid tokens, or the return format. This is insufficient for a permission check tool.

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 two lines, including purpose and parameter format examples. It is front-loaded and efficient, though slight formatting improvements could enhance readability.

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 sibling tools, the description covers the core purpose and parameter usage but lacks details on return values, error handling, or when to choose this tool over similar ones.

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%, so the description must compensate. It explains required_scopes and required_roles as comma-separated lists with examples, adding meaning beyond the schema. However, the token parameter is not described.

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 tool checks if a JWT token has required scopes and roles, using specific verbs and resources. It distinguishes from siblings like validate_jwt (token validity) and decode_jwt (token decoding) by focusing on authorization checks.

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 use for permission checks but lacks explicit guidance on when to prefer this over alternatives such as validate_jwt or list_token_scopes. No exclusion criteria or context are provided.

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

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

No annotations provided, but the description covers key behavioral traits: it decodes without signature validation and returns three components. Missing details on error handling or token format, but acceptable for a simple tool.

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?

Three concise sentences with no redundant information. Front-loaded with core action and constraints.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

For a simple tool with one parameter and no output schema, the description sufficiently explains what it does and what it returns. Could mention error cases, but overall adequate.

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%. The description does not elaborate on the 'token' parameter beyond its name, missing the opportunity to specify expected format or constraints (e.g., 'a valid JWT string'). Minimal value added over the parameter name.

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?

Description clearly states the tool decodes a JWT without signature validation and returns header, payload, and metadata. This distinguishes it from sibling tools like validate_jwt which perform validation.

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?

Indicates it is useful for quick inspection, implying use cases. While it does not explicitly mention when not to use, the sibling validate_jwt provides an alternative for validation, making the intended use clear.

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

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 indicates the output (list of endpoints) but does not disclose potential side effects (network call), error conditions, or required permissions. The expected behavior is partially transparent.

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 three concise sentences: first states the action, second lists output, third gives examples. It is efficiently front-loaded with no unnecessary text.

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 tool with one parameter and no output schema, the description adequately covers purpose and output. It could be more complete by mentioning that it makes an HTTP request and that the issuer_url must be a valid URL, but it is sufficient for the given complexity.

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?

With 0% schema description coverage, the description compensates by giving example issuer URLs (e.g., from Google and Microsoft), adding meaning beyond the plain schema title 'Issuer Url'. It helps the agent understand the format and expected value.

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 retrieves the OIDC discovery document and lists returned endpoints (authorization, token, userinfo, jwks_uri). It provides an example issuer_url. The purpose is specific and distinct from sibling tools, though not explicitly differentiated.

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 does not explain when to use this tool versus alternatives (e.g., decode_jwt, validate_jwt). There is no guidance on prerequisites, context, 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.

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

The description discloses the core behavior (extracting roles and identity) and supported claim types (standard claims, Keycloak realm_access/resource_access). No annotations are provided, so the description carries the full burden, and it does so adequately, though error handling or limitations are not mentioned.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Two concise sentences front-load the purpose with no wasted words, making it quick to read and understand.

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?

The description covers the tool's core function and distinguishes it from siblings, but without an output schema, it lacks detail on return format or structure, leaving some ambiguity for an AI 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?

With only one parameter 'token' and 0% schema coverage, the description adds meaning by explaining the token is a JWT used to extract roles and identity, going beyond the schema's bare 'token' label.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for extracting roles, especially from Keycloak tokens, but lacks explicit guidance on when to use this tool vs siblings or any prerequisites.

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

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

With no annotations, the description carries the full burden. It discloses the read-only nature implicitly and mentions auto-detection of IdP, but it does not detail return format, error handling, or constraints like token validity. 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?

Two sentences front-load the core purpose (list scopes/roles/permissions) and a secondary feature (auto-detect IdP). Every word is informative with no redundancy.

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 tool with one parameter and no output schema, the description is mostly complete. It explains the tool's function and a key differentiator (IdP detection). However, additional context about output structure or sibling tool differentiation would enhance completeness.

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 coverage is 0% for the token parameter, but the description does not add new information beyond stating it is a JWT token. The parameter meaning is somewhat inferred from the tool purpose, but no format or requirement details are provided. Minimal added value.

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 that the tool lists all scopes, roles, and permissions from a JWT token, with the additional feature of auto-detecting the identity provider. This specific verb-resource combination effectively distinguishes it from sibling tools like decode_jwt or validate_jwt.

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?

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

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

Given no annotations, the description partially discloses behavior: it performs token introspection against a URL or falls back to local JWT decoding. However, it does not mention side effects, authentication requirements, or error conditions.

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 extremely concise (three sentences) and front-loaded with the standard name and RFC reference. No unnecessary text.

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?

Despite low complexity, the description is incomplete: it lacks explanation of return values, when to provide client credentials, and how it differs from similar sibling tools like decode_jwt. Output schema is absent.

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%. The description only adds meaning for introspection_url (optional, fallback behavior). Other parameters (token, client_id, client_secret) are not explained beyond their names and defaults.

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?
