ds_delete_ticket

Revoke an existing iRODS ticket by providing the ticket string. Only issuers or admins can delete it; anonymous callers are rejected.

Instructions

Revoke an existing iRODS ticket. Issuer or admin only — the server enforces this. Anonymous callers are rejected at the tool layer.

A4/5.0
Behavior4/5

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

With no annotations, the description carries the full burden and does well: it discloses that authorization is server-enforced (issuer/admin) and that anonymous callers are rejected at the tool layer, which tells the agent about both permission needs and failure behavior. It stops short of saying whether revocation is reversible or what happens to already-issued tickets, leaving some behavioral gaps.

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

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with the action, then the authorization constraint and the rejection behavior. No filler and nothing redundant.

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

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter, no-output-schema, no-annotation tool, the description covers purpose, the authorization model, and caller rejection. It is largely complete, though a note on reversibility or behavior for expired/already-used tickets would close the remaining gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for the single required 'ticket' parameter, so the schema already defines it as the ticket string to delete. The description adds no syntax, format, or sourcing detail beyond that, matching the baseline 3 when the schema does the heavy lifting.

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

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (Revoke) and resource (an existing iRODS ticket), which cleanly distinguishes it from the sibling create/modify/use/list ticket tools. An agent can identify this as the deletion counterpart without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

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

The description supplies preconditions (issuer or admin only; anonymous callers rejected), which is useful usage context, but it never states when to choose this over alternatives like ds_modify_ticket or when a ticket should be revoked rather than left to expire. Usage is implied rather than routed.

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