metadata_render_listing

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

No annotations are provided, so the description carries the full burden. "Sync" and "fill" imply a write to listing.json, but the description says nothing about what gets overwritten, whether existing values are preserved, idempotency, permissions, or failure behavior.

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 dense sentence that front-loads the core action and parenthetically enumerates the store locales/IAP copy slots scope. It is appropriately short and free of filler, though the parenthetical is cryptic rather than clarifying.

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?

An output schema exists, so return values needn't be explained, but with no annotations, an undocumented required parameter, and no usage context, the definition is thin for an operation that mutates repository files. An agent could not reliably know when or how to call it correctly.

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?

There is a single parameter, app_dir, with 0% schema description coverage, and the description never mentions it or clarifies its expected form. With one opaque param and no compensating text, the description leaves the schema to speak for itself when the schema doesn't.

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 states a verb ("Sync") and resource ("listing.json to the spec"), plus the sub-content it touches (store locales, IAP copy slots, legal URLs). However, the meaning of "listing.json" and "spec" is jargon-dependent, and it does nothing to distinguish itself from siblings like metadata_check, metadata_listing_check, metadata_export, or legal_render.

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 statement of when to run this versus metadata_check, metadata_export, metadata_listing_check, or legal_render, nor any prerequisite or ordering guidance. The agent is left to infer usage entirely from the name.

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