postfader_creation_readiness

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

The description explicitly states 'without changing FL Studio' which is a behavioral trait that matches the annotations (readOnlyHint=true, destructiveHint=false). The annotations already provide readOnly and non-destructive hints, so the description adds the concept of 'aggregate' which is not in annotations but is a small additional behavioral clarification. However, it doesn't disclose what happens if blockers are found or if it returns normally or throws. The description is consistent with annotations, so no contradiction.

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 a single sentence with exactly three word chunks: 'Aggregate all detectable setup blockers without changing FL Studio.' It is concise stubcount and front-loaded with the main verb and object database. It is appropriately sized for the complexity of the tool, and every word contributes to understanding the primary behavior and safety property. No extra words 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?

Given the complexity of the tool with a large input schema and an output schema (which hedges on return details), the description is sufficient to understand the tool's core purpose. The annotations provide read-only and non-destructive hints, and the schema fully defines the inputs. The description adds the key element that it aggregates blockersaints without modifying state, which is complete for an agent to decide when to call it. The only missing piece is when to use it (e.g., before execution), but that is not essential for invocation

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 schema for the two parameters (request and plan) is fully described with descriptions in the schema, so the schema documentation coverage is 100%. However, the description of the tool adds no additional meaning beyond what the schema provides. The parameters are complex objects (ProductionRunRequest and ProductionRunPlan), and the schema has extensive definitions, so the agent can infer what they are. The description does not need to elaborate on the parameters since the schema covers them. Baseline is 3 for high coverage.

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 'Aggregate all detectable setup blockers without changing FL Studio' is specific in that it aggregates setup blockers and emphasizes it does not change anything dropped. However, the tool name includes 'creation_readiness', which is a narrow verb-resource pair, but the description does not mention the tool's inputs, only its output. It is also not differentiating enough from siblings like postfader_validate_run, which might also check blockers. The verb 'aggregate' is clear but the object 'setup blockers' is somewhat vague without knowing the context.

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 implies usage is to check for setup blockers without changing state, and is read-only, which is confirmed by annotations. It does not explicitly say when to use this tool vs alternatives like postfader_validate_run or postfader_execute_run. It also does not state that it should be called before execution, which would be a natural usage guideline. The description could be improved by saying 'use before postfader_execute_run to ensure no blockers'.

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