Set All Tracks Targeted

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

Annotations establish it as a non-read-only, non-destructive mutation, so the baseline is lowered. The description still adds meaningful behavior beyond that: it reads back every affected track and only reports 'verified' when all match the requested state, which tells the agent to expect post-write verification semantics it could not get from annotations alone.

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 tight sentences with the core action front-loaded, followed by use context and verification behavior. No filler, no restatement of the title.

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 two-parameter mutation with full schema coverage, a sibling set, and an existing output schema, the description covers purpose, workflow context, and verification behavior adequately. It only lacks explicit sibling disambiguation, which is a minor gap given the name already says 'all'.

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 100%, with both parameters documented including the enum for track_type, so the schema does the heavy lifting. The description adds no semantics beyond the schema, which yields the baseline 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 states a specific verb and resource ('Set all tracks targeted or untargeted'), scoping the operation to the entire track set. It is clear on its own, but it never names the obvious sibling set_target_track (single-track targeting) to differentiate itself, leaving the agent to infer the distinction from the name.

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?

'Useful before insert/overwrite edits' gives a concrete workflow context for when to reach for this tool. It stops short of naming alternatives or stating when-not to use it, so the routing guidance is contextual rather than explicit.

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