Resolve Short Url

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds genuinely useful context beyond them: the API is Technical Preview, and the `space` parameter defaults to the default space, which is behavioral detail the annotations do not supply.

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 plus a parenthetical caveat, with the core action front-loaded. Nearly every phrase earns its place; the parenthetical preview note is short and material.

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?

An output schema exists, so return values need not be explained, and annotations cover the read-only profile. The description covers purpose, the preview caveat, and the space default, though it omits error behavior for an unresolvable slug.

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 carries the burden. It explains `space` well (targets a Kibana space by id, defaults to the default space), but says nothing about `slug` beyond its self-evident meaning from the purpose sentence. Partial compensation for the coverage gap.

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 specific verb ("resolve") and resource ("Kibana short-URL slug") and names the output ("its locator and target app path"), which is far more than a restatement of the name. It does not explicitly reference the obvious sibling create_short_url, but the verb alone distinguishes it from that counterpart.

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 never says when to use this tool versus alternatives (e.g. create_short_url) or when not to. It implies usage by describing the operation, but provides no context, prerequisites, or exclusions.

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