describe_issuance_flow

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

No annotations are provided, so the description carries the full burden for disclosing behavior. It states that the tool 'resolves' the offer and returns the applicable flow, which implies a read/analysis operation rather than a mutating one. It does not address side effects, permissions, or edge cases, but the 'Describe' framing makes the operation's non-destructive nature reasonably clear.

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 definition is two short sentences with no waste; the first sentence states the purpose and the second adds detail about the output (grant-based flow and ordered steps). It is concise and front-loaded, though the first sentence is slightly redundant with the tool name.

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 single-parameter tool with an output schema, the description covers the core purpose and result well. However, it lacks explicit usage boundaries, mentions no sibling alternatives, and does not clarify the credential_offer input format. Without annotations, these gaps leave the agent with some uncertainty about when and how to invoke it correctly.

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 schema has 0% description coverage for the only parameter, so the descrition must compensate. It mentions that the input relates to a 'Credential Offer', but it does not explain the expected string format, encoding, source, or any constraints on credential_offer. This is insufficient for an agent to confidently construct the parameter 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 uses a specific verb 'Describe' and names the resource: the issuance flow for a Credential Offer. It further clarifies the output by saying it returns which grant-based flow applies and its ordered steps. However, it does not explicitly differentiate this from sibling tools like inspect_credential_offer or initiate_issuance, so it stops short of a 5.

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 when the agent needs the ordered steps to obtain credentials from an offer, but it does not explicitly state when to use this tool instead of siblings such as inspect_credential_offer, initiate_issuance, or request_credential. It offers no exclusions, prerequisites, or alternative-routing guidance, so the usage context is only implied.

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