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

No annotations are present, so the description carries the full burden. It discloses that the key is 'discarded,' which hints at no persistence/return of the key, but it does not state side effects, return value, errors, or whether any network/disk access occurs. Too little to be 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 very short and waste-free; both sentences serve a purpose. It could include an example or input mapping, but as a conciseness measure it is strong.

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 9 optional parameters, no required parameter, no output schema, and no annotations, the description is too sparse to let an agent correctly invoke this tool. It leaves ambiguous what to pass and what the result means.

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?

All 9 parameters have descriptions (100% coverage), which meets the baseline, but none of them maps to a 'Jira key' or explains how to supply the key to check. The unrelated parameters (city, feed, json, etc.) actually obscure the tool's purpose, so the schema descriptions add little useful meaning for this tool.

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?

States a clear verb+object ('Check a Jira key shape') and distinguishes from sibling shape tools by naming Jira. However, it never defines what a Jira key shape is or which input parameter carries the key, so the purpose is only moderately clear.

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?

Provides no explicit when-to-use or alternative/comparison guidance. The only usage cue is the purpose statement itself, but there is no instruction about valid inputs or when to prefer this over other shape checkers.

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