Pull Three.js project

pull_project

Compares your revision against the server and returns the project whenever your version is out of date, so you always work with the latest state.

Instructions

Returns the project when the editor revision is stale.

Behavior2/5

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

With no annotations, the description must disclose side effects and behavior. It mentions a staleness condition but does not state whether the tool modifies the project (e.g., overwrites local changes), what happens if the revision is not stale, or any permissions or error behaviors. For a 'pull' operation, this is a significant transparency gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence with no redundant phrasing. It is concise and easy to parse, though the content is sparse. It earns its place but could be more informative.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool likely syncs or pulls project state, the description is incomplete. It does not explain the full flow: what happens when the revision is current, whether the returned project is the latest version, or any error conditions. The output schema covers return structure, but not the tool's overall behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must explain parameter meaning. It hints at 'revision' but does not explicitly describe projectId or currentRevision beyond the schema's format patterns. It does not clarify how the parameters relate to the stale-check logic.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states the tool returns a project, but only under the condition that the editor revision is stale. This gives some purpose but is vague about what 'pull' means (fetch, update, sync) and does not distinguish from sibling tools like inspect_project or open_editor.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. The condition 'when the editor revision is stale' is a behavioral trigger, not explicit usage advice or exclusion of other tools.

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