compare_platforms

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

No annotations are provided, so the description must disclose behavioral traits. It mentions what the tool does (find equivalents, compare coverage, assess portability, build chains), but does not state whether it reads or writes data, requires authentication, or has side effects. The read-only nature is not clarified, leaving the agent uncertain about idempotency.

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 a single sentence that efficiently lists four key capabilities without extraneous words. While it is front-loaded, it could be slightly more structured (e.g., bullet points), but it remains clear and 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?

With 6 parameters (1 required), no output schema, and moderate complexity, the description covers the main purpose but lacks details on return format, prerequisites, or how to use results. Sibling tools are numerous, but the description does not provide enough context to decide when to use this tool over them.

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 coverage is 100%, so all 6 parameters have descriptions. The tool description does not add significant extra meaning beyond the schema; it only reiterates the mode names. Baseline 3 is appropriate as schema already carries the burden.

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 the tool does cross-platform LOL binary comparison with four specific modes (equivalent, coverage_diff, portability, unified_chain). It distinguishes from sibling tools like 'compare_os_versions' by focusing on binary techniques rather than OS versions.

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 implies usage context through the listed modes (e.g., use 'coverage_diff' to compare coverage), but it does not explicitly state when to prefer this tool over alternatives like 'analyze_binary' or 'compare_os_versions'. No exclusion criteria are given.

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