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

With no annotations, the description carries the full behavioral burden and does well: it declares the operation is non-executing, requires authorization plus exact compatibility, and explicitly guarantees no flash command is ever returned. It omits failure modes (e.g. what happens on a compatibility mismatch) and any rate/permission detail, keeping it below a 5.

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?

Two tight sentences, zero filler, and the safety-critical qualifier 'non-executing' is front-loaded before the return-value sentence. Every clause earns its place.

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?

An output schema exists, so the return-value sentence is partly redundant, but it usefully adds the negative guarantee of no flash command. Combined with the preconditions stated, an agent has enough to invoke it correctly; only playbook_id sourcing and mismatch behavior are unaddressed.

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?

Top-level schema coverage is 0%: playbook_id and owner_authorized have no descriptions. The description partially compensates by tying owner_authorized to an authorization requirement and implying 'observed' must yield an exact compatibility match, but playbook_id's provenance is left unexplained. The rich nested 'observed' descriptions live in the schema, not the description.

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 specific verb and resource ('Prepare a ... firmware manifest') and adds the crucial qualifier 'non-executing', which tells an agent this is a planning/assembly step rather than a flash operation. It is reasonably distinguishable from siblings like check_firmware_compatibility or get_firmware_playbook, though it never names an alternative directly.

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?

Gives two concrete preconditions for use: owner authorization and an exact compatibility match, implying the agent should run check_firmware_compatibility first and only proceed when authorized. It stops short of naming alternative tools or stating when not to use it, so it is clear context without explicit exclusions.

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