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

No annotations are provided, so the description carries the full burden. It discloses key behavioral traits: the tool tracks property reads for analysis, supports persistent tracking across page navigations, and has a default max_entries limit. However, it lacks details on permissions, rate limits, or what happens when max_entries is exceeded, leaving gaps for a mutation tool.

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 appropriately sized and front-loaded, starting with the core purpose. It uses bullet points for examples and parameter details, which aids readability. However, the 'Returns' section could be integrated more smoothly, and some phrasing is slightly verbose (e.g., 'Critical for JSVMP analysis' could be tighter).

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?

Given the tool's complexity (monitoring property access), no annotations, and no output schema, the description is fairly complete. It covers purpose, usage context, parameters, and return structure. However, it lacks details on output format (beyond 'dict with status and targets') and potential side effects, which could be improved for a tool with mutation implications.

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%, so the description must compensate fully. It adds significant meaning beyond the schema: explains 'targets' with examples and wildcard usage, clarifies 'persistent' as surviving page navigation, and specifies 'max_entries' default and purpose. This fully documents all three parameters with practical guidance.

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 clearly states the tool's purpose: 'Track property access on specified objects to reveal what environment info is being read.' It specifies the verb ('track'), resource ('property access'), and context ('JSVMP analysis'), distinguishing it from siblings like 'get_property_access_log' (which likely retrieves logs rather than setting up tracking).

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?

The description provides clear context for when to use this tool: 'Critical for JSVMP analysis: reveals which browser properties... the VM reads to generate fingerprints.' It implies usage in fingerprinting scenarios but does not explicitly state when not to use it or name alternatives among siblings, such as 'trace_function' for different monitoring needs.

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