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

Annotations declare readOnlyHint=false, openWorldHint=true, idempotentHint=true and destructiveHint=false, and the description adds real context beyond them: ingestion happens server-side, the asset is returned as a sha256 that must be consumed downstream, and it persists into the downloaded .logicx without a desktop. It does not cover failure modes (bad URL, non-audio content) or confirm whether re-adding the same URL is a no-op despite idempotentHint=true.

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 core action, and the downstream usage follows in a logical order with no filler. It is dense and cluttered with inline object literals and parenthetical asides ('the drum-pack / sample-swap path'), which slightly hurt scanability but each clause carries information.

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 mutating ingest tool with annotations and no output schema, the description supplies what an agent most needs: the return value (sha256) and how to consume it (attach_audio / load_quick_sampler_sample). Remaining gaps are the audio_key input path and error behavior, so it is strong but not exhaustive.

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 75%, so the schema largely documents the inputs already; the description reinforces audio_url semantics (public https, pre-signed links) but adds little on filename. Notably it frames input purely as a URL and never mentions audio_key, the alternate ingestion path that the schema exposes — a meaningful omission for a two-path parameter set.

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 ('Add an audio file to a session') plus the intake mechanism ('from a public https URL'), and immediately scopes it as server-side ingestion returning a sha256. That distinguishes it from local-file paths handled by attach_audio / load_quick_sampler_sample, so an agent can pick it without opening another 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?

Explicit when-to-use (any audio file online, a bounce's pre-signed stem link 'works as is') and when-not-to-use ('A file on the user's machine needs no upload'), with the alternative route named via local_path/sample_path and a pointer to doseedo_edit_ops_reference. This is close to a complete routing decision.

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