A3.7/5.0

Behavior4/5

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

Annotations already declare destructiveHint=true, idempotentHint=false and readOnlyHint=false, so the safety profile is covered. The description adds substantive context beyond that: stopped transport, macOS English Live, binding saved references and source bytes, verifying Project-relative sample copies, large library copying, and an explicit no-portability-guarantee caveat. It stops short of saying what existing Set content is overwritten.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The purpose is front-loaded in the first sentence, followed by compact precondition and caveat sentences. Each sentence carries information, though the telegraphic phrasing ('Binds saved references and source bytes') is dense and the final caveat sentence is somewhat cryptic.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive, non-idempotent operation with an output schema and full parameter coverage, the description supplies the key preconditions, side effects and caveats an agent needs. It does not define the four media categories or state whether an existing saved Set is overwritten, but overall it is complete enough to call correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and all five parameters are documented in the schema, including dryRun, planHash and confirmationToken. The description adds no parameter-level meaning and does not mention the plan/confirmation workflow, so the baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: 'Collect all four native media categories into the current Project and save its clean named Live 12 Set.' An agent can distinguish this from the read-only sibling get_project_media, though the description never names that sibling or save_live_set explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives real preconditions ('Requires stopped transport and macOS English Live') and a caution ('Can copy large libraries'), which implies usage context. It never states when to choose this over get_project_media or save_live_set, or when not to use it, so guidance remains implicit rather than explicit.

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