mcp_opendaw_add_signature_change

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

No annotations are provided, so the description carries full burden. It explains that the tool creates a SignatureEventBox on the timeline's signature track and returns details. However, it does not mention potential conflicts with existing signature changes at the same position or idempotency, which would strengthen transparency.

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?

The description is concise, using only three sentences: purpose, distinction from sibling, and parameter descriptions. No redundant information; every sentence serves a purpose.

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?

Given no annotations and three parameters, the description adequately covers the tool's function and parameter semantics. It mentions the return value (signature event details) and the effect on the signature track. Could provide a bit more about behavior with existing events, but it's largely complete.

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?

The description fully explains each parameter: position_beats (position in beats), numerator (beats per bar), denominator (note value per beat with examples). Since schema coverage is 0%, this compensates completely, adding meaning beyond type and title.

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 clearly states the tool adds a time signature change at a specific position, using a specific verb ('Add') and resource ('SignatureEventBox'). It distinguishes itself from the sibling tool 'set_time_signature' by explaining the difference (global vs. mid-track).

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?

The description explicitly contrasts with 'set_time_signature' and explains when to use this tool (for mid-track changes). It provides an example (4/4 → 3/4 → 4/4) to illustrate usage, making the context clear.

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