Spine texture pack

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

With no annotations, the description alone must inform about behavioral traits. It only states the action and configuration options but does not disclose side effects (e.g., overwriting output), permissions needed, performance impact, or failure modes. For a tool with 8 parameters, this is insufficient.

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 conveys the core action efficiently without any filler. It is front-loaded with the primary purpose, making it easy for an AI agent to grasp quickly.

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 (8 parameters, no output schema, no annotations), the description is too brief. It does not explain the packing process, output format, constraints, or any prerequisites, leaving significant gaps for an AI agent to understand correct usage.

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 63%, and the description adds some context for the 'pack' parameter by mentioning 'default settings or a pack settings JSON file'. However, it does not clarify the purpose of parameters like spinePath, timeoutMs, or updateVersion, which lack schema descriptions. The baseline of 3 is appropriate as the description provides marginal added value.

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 verb 'Pack' and the resource 'image folders into a Spine texture atlas', making the tool's purpose unambiguous. It distinguishes itself from sibling tools like spine_export (which exports in other formats) and spine_summarize_atlas (which summarizes existing atlases).

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 mentions using 'default settings or a pack settings JSON file', implying two usage modes, but does not provide explicit guidance on when to use this tool versus alternatives like spine_export or when not to use it. No exclusion criteria or named sibling comparisons are given.

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