flat_create_score

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

With no annotations, the description carries the full burden. It does disclose two useful traits: the score is private by default and the accepted source formats. It does not state authentication/ownership requirements, what happens if both musicxml and file_path are supplied, or what occurs on parse failure.

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?

A single front-loaded sentence with no filler that states the action, the default privacy, and the accepted inputs. It is efficient, though the parenthetical extension list slightly crowds the core statement.

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 5-parameter write tool with no annotations and no output schema, the description leaves meaningful gaps: no ownership/permission context, no conflict rule between the two input sources, and nothing about title or collection semantics. What it does cover (privacy default, source formats) is accurate but not sufficient on its own.

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 0%, so the description must compensate, and it does partially: it clarifies that musicxml is raw XML text and that file_path points to a local .musicxml/.xml/.mxl/.mid file, which is real added meaning. However, 'title' and 'collection' are never explained, and the mutual exclusivity/precedence of musicxml vs file_path is left ambiguous.

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?

The description uses a specific verb and resource ('Cria uma partitura nova') and names the accepted input sources (MusicXML text or a local file), so an agent can tell it is a creation tool rather than a revision or fork operation. It does not name any sibling, so differentiation from flat_upload_revision / flat_fork_score is only implicit.

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?

There is no statement of when to use this tool versus alternatives such as flat_upload_revision (add a revision to an existing score) or flat_fork_score (copy an existing score). The only guidance is the implied 'use this to create something new', which the agent could infer from the name alone.

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