browser_session_health

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

No annotations provided, but the description fully discloses the read-only diagnostic nature. It lists what information is retrieved, implying no destructive effects. Could be more explicit about lack of side effects, but very clear overall.

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?

Single sentence packed with all relevant information: tool purpose, data points, and usage guidance. No redundancy, front-loaded, highly concise.

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 diagnostic tool with no parameters and no output schema, the description provides complete context: what it retrieves, when to use it, and how it relates to sibling tools. No gaps.

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 in schema (0 params, 100% coverage). Description doesn't need to add parameter info, and baseline for 0 params is 4. No further context needed.

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 explicitly states it provides a diagnostic snapshot of the bridge and active session, listing specific data points (bridge mode, extension connectivity, etc.). Clearly distinguishes from other browser tools by focusing on health diagnostics.

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?

Explicitly says 'Use when something feels stuck before reaching for browser_session_end,' providing clear context and an alternative. This tells the agent when to invoke and when not to.

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