v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the entire behavioral burden and largely fails to. It does not say whether the check is read-only, whether a shared boundary endpoint counts as a collision, whether all collisions are reported or the first one aborts, or anything about the result shape for a tool with no output schema.
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?
A single front-loaded sentence with no filler or repetition. It is efficient, though its brevity is also the source of the missing behavioral and usage detail rather than a virtue in itself.
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 tool with no annotations and no output schema, the description should explain the safety profile and at least sketch what a collision result looks like. It gives only the domain of the check, leaving the agent unable to predict the response or the exact collision criteria.
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 reported at 100% and the sole parameter is documented as "List of memory regions to check for collision," so the baseline is 3. The description adds nothing further, and the genuinely ambiguous semantics of start/end (units, whether end is inclusive or exclusive) are left unaddressed by both schema and description.
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 ("detect") and resource (memory layout collisions) and enumerates the region kinds involved (buffers, heaps, display lists, texture staging areas). An agent can distinguish it from memory_check_alignment and memory_inspect_region by domain, though the description never explicitly contrasts with those siblings.
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 when-to-use or when-not-to-use guidance, and no mention of the closely related siblings memory_check_alignment or memory_inspect_region. The agent must infer from the purpose sentence alone that this is the multi-region overlap check rather than the per-region inspection or alignment tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
