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

Annotations already declare the mutation safety profile (readOnly=false, destructive=false, idempotent=false, openWorld=true). The description adds genuinely useful context beyond that: the session is created empty, and the call returns a session_id needed by downstream tools. No output schema exists, so naming the return value is a real contribution.

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?

One sentence, front-loaded with the core action, followed by the useful workflow hand-off and return value. Nothing 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?

For a simple two-parameter creation tool with full annotations and full schema coverage, this covers the essentials. A minor gap: it doesn't explain the implication of the "daw" binding for later operations, though the schema enum and default largely handle that.

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 coverage is 100% and both parameters (name, daw enum with default logic) are fully documented in the schema. The description adds no parameter-level detail beyond that, so the baseline 3 applies.

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 ("Create a new, empty DAW session") and the scope ("in the account"), plus what it returns. The word "empty" distinguishes it from siblings like doseedo_session_from_stems and doseedo_import_project, which also produce sessions.

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?

Explicitly names the follow-on tools (doseedo_edit_session to populate, doseedo_audio_to_session to target), giving the agent a clear workflow context. It does not state when NOT to use it (e.g., prefer session_from_stems when stems already exist), so it falls short of full when/when-not guidance.

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