diff_projects

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

With no annotations, the description carries full burden. It discloses that the tool is read-only and performs a diff of specified aspects. However, it does not describe behavior like error handling, password usage, or performance implications. Still, it provides a good overview of what the tool does.

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, well-structured sentence that immediately conveys the tool's purpose. It is front-loaded with the key concept ('Semantic diff') and lists specifics concisely. No unnecessary words.

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 presence of an output schema (not shown), the description does not need to detail return values. It adequately explains the tool's role within the set of sibling tools. A brief mention of output type or the meaning of 'diff' could enhance completeness.

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 adds meaning for path_a and path_b by clarifying their roles as base/old and new, which the schema does not specify. However, password_a and password_b are not explained, though they are optional and likely self-explanatory. Given 0% schema coverage, the description partially compensates.

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 it performs a semantic diff between two .knxproj files, specifying the exact aspects compared (added/removed GAs, DPT changes, renames, security-flag changes). This differentiates it from sibling tools like analyze_all or check_* tools, which have different scopes.

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 (comparing two project files) but does not explicitly state when to use this tool versus alternatives. There is no mention of when it should not be used or any exclusions. The 'Read-only' hint is useful but not a usage guideline.

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