set_sequence_in_out_points

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

With no annotations, the description carries full burden but only states the basic action. It does not disclose whether setting one point preserves the other, whether an active sequence is required, or whether the operation is destructive to existing points. This is a mutating operation with no behavioral context added.

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, front-loaded sentence with no extraneous information, earning a perfect score.

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?

While the description names the action and the schema documents parameters, the tool lacks annotations and the description omits important context such as required sequence state and behavior when only one point is set, so it is only minimally complete for a simple setter.

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% for all three parameters, and the description adds no additional semantics beyond the schema. The phrase 'in and/or out' hints at optionality but doesn't clarify that both are optional in the schema, potentially leaving room for confusion about calling with only sequenceId.

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 the verb 'Sets' with a specific resource 'in and/or out points on a sequence timeline', clearly distinguishing it from sibling tools like set_source_in_out or set_item_in_out by specifying the target as the sequence timeline.

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 for setting sequence in/out points but provides no explicit guidance on when to prefer it over alternatives like set_source_in_out or clear_sequence_in_out, nor does it mention any prerequisites such as an active sequence.

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