storekit_generate

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

No annotations exist, so the description carries the burden. It usefully discloses that the operation is deterministic, derived from app.spec.json, and what content is emitted. However, it never states that the write overwrites any existing Configuration.storekit, nor anything about path resolution or failure behavior, which matters for a file-producing tool.

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?

Two tightly packed sentences: the primary action and output path come first, followed by the determinism/timing note. No filler, no repetition of the tool name.

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 an output schema present, return values need not be described, and the description covers source, destination, and generated contents. The remaining gap is overwrite/side-effect semantics on an existing StoreKit file, which is not addressed.

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 0% and the single required parameter app_dir is documented nowhere. The description says the file comes from 'the app's app.spec.json' but never explains that app_dir locates that spec or how paths are resolved, so it fails to compensate for the coverage gap.

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?

States a specific verb (Write) plus the exact output artifact (Resources/Configuration.storekit) and the input source (app.spec.json). It also enumerates what the file contains (group, levels, intro offers, offer product, en_US), so it is clearly distinguishable from the similarly named sibling storekit_parity.

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?

Gives explicit timing guidance: 'run after any product change.' That is a clear context for invocation, but it never names an alternative tool or states when not to run it, so it stops short of full routing guidance.

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