Stop an active recording and delete the capture immediately, closing the browser without uploading. Use when the session captured the wrong content or encountered an error.
Discard the active recording session: closes the browser and deletes the capture. Nothing is uploaded. Use this when the session captured the wrong thing or an error made it worthless.

v0.8.6Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, description fully discloses behavioral traits: closes browser, deletes capture, no upload. No contradictions. Transparent about the destructive nature of the action.
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?
Two concise sentences, front-loaded with core action. Every sentence adds value with no redundancy.
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?
For a simple, parameterless tool, description completely explains outcome and use case. No missing information.
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?
No parameters exist (100% schema coverage implicitly), so description need not add param info. Baseline 4 applies as schema already covers everything.
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?
Description clearly states verb ('discard') and resource ('active recording session'), with distinct actions: close browser, delete capture, nothing uploaded. Differentiates from sibling tools like 'stop_recording' which likely preserves the capture.
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?
Provides explicit when-to-use scenarios ('when the session captured the wrong thing or an error made it worthless'), but does not explicitly mention when not to use or point to alternatives. Given zero parameters and simple behavior, guidance is adequate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
