v0.1.2Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description alone must disclose side effects, state changes, outputs, and caveats. It only mentions deterministic sequences and adaptive timing; it does not explain what capturing does to stored recordings, whether replay is available, or what the tool returns.
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 compact sentence with no filler, and the core idea is front-loaded. It loses points only because brevity comes at the cost of crucial details.
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?
With no annotations, no output schema, six parameters, and no parameter descriptions, this one-sentence description is far from complete. It does not tell the agent how to invoke the tool, what arguments mean, or what outcome to expect.
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%, and the description does not explain any of the six parameters such as name, frames, project, execution_id, or recording_id. The agent has no semantic guidance beyond the enum on action, so it cannot correctly populate parameters.
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 names a specific verb and resource: capturing or replaying deterministic browser action sequences. However, it is ambiguous against siblings such as load_behavior, and it misleadingly says 'replay' when the only supported action enum values are 'capture' and 'list'.
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 guidance on when to use this tool instead of load_behavior, register_trigger, or other siblings. The phrase 'with adaptive timing' hints at a use case but does not state conditions, prerequisites, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
