pr_createBin

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

Annotations already declare this is a non-read-only, non-destructive, closed-world mutation, lowering the bar. The description adds a real behavioral detail — intermediate bins in a nested path are created — but says nothing about behavior on duplicate paths, where the bin lands (project root vs. current bin), or whether the call is idempotent.

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 front-loaded sentence: app, verb, resource, then the one non-obvious constraint. No filler.

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?

For a one-parameter mutation with annotations covering the safety profile and no output schema, the definition covers the essentials but omits the prerequisite context (active project/document) and what the caller gets back (the new bin's identifier or item path), which an agent chaining this into a follow-up move would need.

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?

With one parameter and 0% schema description coverage, the description must carry path semantics, and it does supply a concrete format example ("Footage/Day 1"). It still leaves unresolved whether the path is relative to the project root, whether a leading slash or trailing slash is legal, and how name collisions are handled.

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 and resource ("create a bin") scoped to Premiere Pro, so an agent knows exactly what is produced. No sibling tool creates bins, so differentiation is implicit rather than stated, keeping it just short of a 5.

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 parenthetical about nested paths implies the tool is used to build a folder hierarchy, but the description never says when to create a bin versus placing media directly, whether an active project is required, or what to do if the bin already exists. Usage has to be inferred.

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