set_strip_property

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

No annotations are provided, so the description carries the full behavioral burden. It states that settings are changed and gives return fields, but it does not explain merge-versus-replace semantics, mutation side effects, permissions, validation behavior, or what happens when optional groups are omitted.

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 front-loaded with the core action, then organized by Args and Returns. It is appropriately sized, though the Returns section is somewhat redundant because an output schema exists.

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?

The parameter groups are well explained and return information is present, which is useful even though an output schema exists. However, for a mutation tool with no annotations and 0% schema description coverage, key behavioral details about merge semantics and side effects are missing.

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 0%, but the description meaningfully compensates by giving examples for settings, text-strip-specific keys, transform units, and crop bounds. It is not exhaustive for all possible settings keys, but it adds substantial semantic value beyond the generic object schema.

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 first sentence names a specific verb and resource: change a sequencer strip, including its settings, position, and crop. This clearly distinguishes it from siblings such as add_sequencer_strip, remove_strip, and list_strips.

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?

Usage is implied: modify an existing sequencer strip rather than add, remove, or list strips. However, it does not explicitly say when to use this versus related tools or what preconditions must hold, such as whether the strip must already exist or be selected.

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