flipper_unlock_desktop

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

Annotations already indicate non-destructive mutation (readOnlyHint=false, destructiveHint=false). The description adds 'unlock' which aligns with mutations. It does not disclose additional behaviors like side effects or prerequisites (e.g., device must be connected), but given the low complexity, this is adequate.

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 a single, front-loaded sentence with no superfluous words. It earns its place by stating the tool's purpose and condition efficiently.

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 tool with one optional parameter and no output schema, the description is nearly complete. It could mention connectivity prerequisites, but overall it provides sufficient context for an agent to operate correctly.

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 the schema fully documents the optional 'port' parameter. The description adds no extra meaning beyond the schema, meeting the baseline score of 3.

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 clearly states the tool's action ('Unlock the device's desktop') and condition ('if it is locked'). It uses a specific verb and resource, distinguishing it from sibling tools like flipper_connection_status or flipper_reboot.

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 implies when to use (when locked) but does not explicitly state when not to use or provide alternatives. However, the context is clear enough for an agent to infer reasonable use.

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