raw_last_track

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

No annotations are present, so the description must disclose behavioral traits. It does warn that it 'may open a dialog or change project state,' which signals potential side effects. However, it does not specify what dialog or what state changes, leaving an agent uncertain about what to expect. This is a partial disclosure, not a thorough one.

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 short and front-loads the action: 'Focus the last track.' The phrase 'Static no-argument Audacity action' is somewhat redundant since a zero-parameter schema already implies no arguments, but it adds minimal overhead. The caution is appended at the end. Overall, it is efficient with little waste.

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 no-parameter action, the description covers the basic operation and a warning about side effects. However, it leaves out what 'last track' means precisely (e.g., the last in selection order or project list) and does not explain the potential dialog or state change in enough detail for an agent to fully predict outcomes. It is adequate but not comprehensive for a tool that might mutate project state.

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?

The tool has zero parameters and the schema fully covers an empty object. According to the rule, a tool with no parameters gets a baseline of 4. The description adds no parameter-specific details because there are none to explain. This is appropriate.

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 the action clearly: 'Focus the last track.' It identifies the resource and verb. However, it does not explicitly contrast with siblings like raw_first_track or raw_next_track, though the 'last' qualifier implies a distinction. That leaves some ambiguity about whether it selects, moves to, or highlights, but the core purpose is clear.

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?

No guidance on when to use this tool versus alternatives. It does not mention raw_first_track or other track-navigation tools, nor does it explain a scenario where 'last' is preferred. The caution to 'inspect the command name first' is a safety hint, not usage guidance.

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