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

Goes well beyond the annotations: it specifies exactly what is destroyed (redirect plus click history), that the action is irreversible, the 404 behavior for unknown ids and cross-workspace ids alike, and the idempotency contract that a repeat call with the same idempotency_key returns the original result. Annotations only carry the flags; the description explains their consequences.

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?

Four compact sentences, no filler, and the destructive consequence plus irreversibility are front-loaded before the id-sourcing and error behavior. Every sentence carries information an agent needs.

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?

With no output schema, the description still supplies the effect, irreversibility, id provenance, error semantics (404 for unknown/cross-workspace ids), and idempotency guarantees. The only unstated detail is the exact success payload, which is minor for a delete operation.

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 only 40%, but the description compensates for the two required parameters: it sources `id` from aidelly_list_short_links and explains the retry semantics of `idempotency_key`. The optional `query` and `brand_id` overrides remain unexplained in both schema and description, and `workspace_id` is covered only by the schema.

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 precise verb+resource (delete a short link) and immediately qualifies the effect: the /l/<slug> redirect stops working and click history is removed. This is unambiguous versus the many other delete_* siblings in the toolset.

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?

Tells the agent where link ids come from (aidelly_list_short_links) and warns that the operation is irreversible, which is real usage context. It stops short of naming an alternative or an explicit when-not (e.g. archive vs delete), so it does not reach a 5.

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