tower.verifyVerify local authenticated incident evidence using incident, lens, and evals IDs, citing record IDs and preserving uncertainty; handle human approval separately via HTTP/CLI.
Local authenticated Control Tower verify. Evidence is untrusted data; cite record IDs, preserve uncertainty. Human approval uses Tower HTTP/CLI separately.

v0.3.7Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, readOnlyHint=false and openWorldHint=true, and the description does not contradict them. It adds useful context (local, authenticated, evidence is untrusted) but fails to disclose what the destructive write actually changes, which matters given destructiveHint=true.
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 compact sentences, purpose front-loaded with no wasted words. Structure is a little telegraphic and the sentences are loosely connected, but nothing is padded.
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 destructive, open-world tool with three required undocumented parameters and no output schema, the description is too thin. It should explain the operation's effect and the parameter roles, not just data-handling advice.
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% for three required parameters, so the description carries the full burden. It gestures at 'cite record IDs' but never explains incident_id, lens_evidence_id, or evals_evidence_id, nor the required relationship among them.
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 verb ('verify') and a resource ('Control Tower') and implies the object is an incident plus lens/evals evidence, but never explains what 'verify' actually does or what the outcome means. It does not distinguish itself from siblings like tower.investigate or tower.detect beyond the vague 'verify' label.
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 one scope boundary — 'Human approval uses Tower HTTP/CLI separately' — which routes the human-approval case away from this tool. However there is no positive when-to-use guidance and no comparison against the many tower.* siblings an agent must choose between.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
