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

Annotations already declare readOnlyHint=false, idempotentHint=false, destructiveHint=false, and openWorldHint=true, so the description's burden is lower. It adds useful non-schema behavior: the session is created empty, it lands in the account, and the call yields a session_id the agent needs for subsequent calls. It does not say whether repeated calls with the same name create duplicates (relevant given idempotentHint=false) or what quota/permission limits apply.

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?

Two compact sentences, front-loaded with the action and the blank-project clarification, then the return value. No filler or 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 simple two-parameter creation tool with full schema coverage and annotations, the definition supplies everything needed to invoke it correctly, including the return value in lieu of an output schema. Minor remaining gaps are duplicate-name behavior and any account-level limits.

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 'name' and the 'daw' enum already documented in the schema, so the schema carries the parameter semantics. The description adds nothing about the daw binding (e.g. what happens if omitted, whether it can be changed later), so the baseline of 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 in the account') and immediately disambiguates from the neighboring edit tool by describing the result as 'a blank project you can then populate with doseedo_edit_session'. An agent can distinguish this from doseedo_edit_session, doseedo_import_project, and doseedo_add_audio_to_session without opening any schema.

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 frames the create-then-populate workflow by naming doseedo_edit_session as the follow-up, which gives clear context for when this tool is the right entry point. It stops short of naming exclusions, e.g. when to use doseedo_import_project instead if the user already has a project file, so it is clear context rather than a full decision rule.

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