get_project_overview

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

readOnlyHint=true already establishes the safety profile, so the bar is lower. The description adds genuine value by disclosing the exact scope of returned state (edit cursor, time selection, FX chains, item counts), which is not derivable from the annotations.

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?

Front-loaded with the two-word directive 'Start here,' followed by a dense enumeration of return contents. It is a single run-on sentence, but every clause names a distinct piece of state, so little is wasted.

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?

No output schema exists, so the description carries the full burden of explaining return values — and it does so comprehensively, listing every category of project state returned. For a zero-argument read tool, nothing an agent needs in order to call it is missing.

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?

Zero parameters, so per the rubric the baseline is 4. There is nothing further for the description to clarify about inputs, and it correctly omits param discussion.

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 ('Returns') and enumerates the exact contents: tempo, time signature, transport state, master track, every track with its properties, and selected items. This is a distinct aggregate-snapshot resource that an agent can clearly separate from single-purpose siblings like get_track_details or get_tempo_map.

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?

'Start here' is a clear directive that this is the orientation/entry-point call, which is meaningful usage guidance for an agent beginning a session. It stops short of naming alternatives or exclusions (e.g. 'use get_track_details for a single track'), so it isn't the full when/when-not treatment.

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