Tower execute

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

Annotations already declare destructiveHint=true, readOnlyHint=false and openWorldHint=true, so the safety profile is covered. The description still adds real context beyond them: a local authentication requirement, that evidence returned is untrusted data requiring ID citation and preserved uncertainty (injection-safety guidance), and that approval is a separate out-of-band step. It stops short of saying what state is mutated or whether the action is reversible.

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?

Three short sentences with no filler, and the terse data-handling constraints are compact rather than padded. The main weakness is ordering: a vague purpose statement leads while the more informative approval boundary is buried at the end.

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 flagged-destructive mutation with no output schema and 0% parameter documentation, the description is too thin: it does not describe what gets changed, what the result looks like, failure modes, or how preview_digest ties to prior previews. Key context an agent needs before invoking a destructive tool is missing.

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% and the description never mentions either parameter. The critical semantics of preview_digest — that it must correspond to a prior tower.preview — and the meaning of incident_id are left entirely unstated, so the agent gets no help beyond the bare field names.

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?

"Local authenticated Control Tower execute" largely restates the name/title; it never says what is being executed (presumably applying a previewed incident action). The only differentiating element is that human approval happens elsewhere, which hints at scope but does not state the action performed.

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 states one boundary ("Human approval uses Tower HTTP/CLI separately") but gives no when-to-use guidance relative to the obvious siblings tower.preview and tower.verify, despite preview_digest implying this runs after a preview. No preconditions or lifecycle ordering are provided.

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