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

Annotations already cover the safety profile (readOnlyHint=false, destructiveHint=false, openWorldHint=false), so the bar is lower, but the description adds nothing beyond them. It does not say whether the removal is undoable, whether all effects in a stack are wiped or only top-level ones, or what happens to clips that have no effects. There is also a mild tension between 'Remove all effects' and destructiveHint=false that the description does nothing to resolve.

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 single sentence is front-loaded and free of filler, which is good. But for a bulk mutation on multiple clips, one sentence is under-specified rather than genuinely concise, leaving the agent to guess at scope and side effects.

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?

There is no output schema and no annotation detail on reversibility, so the description carries the burden for a bulk edit affecting many clips at once. It omits return behavior, error conditions, and scope semantics, leaving the definition inadequate for the tool's complexity.

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 only 50%: projectId is documented in the schema as defaulting to the open project, but clipIds has no description at all. The tool description does not compensate, saying nothing about whether clipIds accepts one or many clips, whether unknown IDs cause errors, or whether the array can be empty.

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 gives a specific verb and resource: 'Remove all effects from clips', so the bulk-clearing nature of the operation is clear. However, it never distinguishes itself from the closely related siblings remove_effect (single effect) and copy_effects, so an agent must infer the difference from the name alone.

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 instead of remove_effect, or when not to use it. No prerequisites, no note about whether clips without effects are tolerated, and no mention of the relationship to projectId targeting.

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