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 mentions what the output shows (regions, permissions, gaps, symbol annotations) but doesn't disclose behavioral traits like whether it's read-only, if it requires specific permissions, potential performance impact, or output format details. For a tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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: the first sentence clearly states the purpose, followed by additional details and parameter documentation. There's no wasted text, though the parameter documentation could be more informative given the schema coverage gap.

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 complexity (memory mapping tool with no annotations, 0% schema coverage, and no output schema), the description is incomplete. It doesn't explain the output format, how to interpret the layout, error conditions, or dependencies on other tools (e.g., requiring a session from 'create_emulator'). For a tool in a debugging/emulation context, this leaves too much unspecified.

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?

The description includes an 'Args:' section that documents the single parameter 'session_id', but with 0% schema description coverage, this adds minimal value beyond the schema's title 'Session Id'. It doesn't explain what a session_id is, how to obtain it, or its format, failing to compensate for the low schema coverage adequately.

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: 'Produce a /proc/self/maps-style layout of the address space' with specific details about what it shows (regions, permissions, gaps, symbol annotations). It uses a specific verb ('Produce') and resource ('layout of the address space'), but doesn't explicitly differentiate from sibling tools like 'list_regions' or 'hexdump', which might have overlapping functionality.

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 no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools like 'list_regions' or 'hexdump' that might serve similar purposes, nor does it specify prerequisites or contexts for usage beyond the required session_id parameter.

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