unlock_door

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

With no annotations provided, the description carries full responsibility, and it delivers. It flags the action as physical-security-sensitive, states the confirmation requirement, and discloses that calling with confirm=false is a no-op that returns a reminder instead of unlocking.

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 two sentences with no filler. It front-loads the core action, then packs the security warning, caller precondition, and confirmation behavior into compact, high-value language.

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 simple two-parameter physical-security action with no output schema, the description covers everything needed to invoke it correctly: the requirement for explicit user consent, the needed confirmation flag, and the no-op fallback. Nothing critical 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 coverage is 100%, so parameters are already documented. The description adds meaningful behavioral context beyond the schema by specifying that confirm=true is required and that false leads to a no-op reminder, which is not fully captured in the schema alone.

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?

The description states a specific verb and resource: 'Unlock a Kwikset door.' It is immediately distinguishable from sibling tools like lock_door and list_locks, leaving no ambiguity about the tool's function.

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 gives explicit when-to-use guidance: only after the user has explicitly asked to unlock this specific door. It also requires confirm=true and explains that confirm=false is a deliberate no-op, providing clear behavior boundaries.

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