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

With no annotations, the description carries full burden. It lists sequential actions but lacks critical behavioral details: whether operations are atomic/rollback on failure, what permissions are needed, whether it modifies existing branches, what happens if dependencies fail to install, or what output/errors to expect.

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?

Extremely concise single sentence listing all key actions. Front-loaded with no wasted words. Every clause earns its place by specifying a distinct step in the workflow.

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 5-parameter mutation tool with no annotations and no output schema, the description is insufficient. It omits error handling, success criteria, side effects, and doesn't explain the relationship between parameters like startPoint and branch. Should provide more context for safe invocation.

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 40% (only 2 of 5 params have descriptions). The description mentions 'install dependencies' which hints at installWithLegacyPeerDependencies, and 'create and push a branch' relates to branch/startPoint, but doesn't explain currentWorkingDirectory or commitMessage semantics beyond schema. Baseline 3 as schema covers some ground.

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 tool's purpose with specific verbs (set, pull, create, push, install) and resources (remote URL, changes, branch, dependencies). It distinguishes from siblings like install_dependencies by including git operations, but doesn't explicitly contrast with vcs tools like vcs_status or vcs_log.

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?

No explicit guidance on when to use this tool versus alternatives. The description implies it's for starting work on a project, but doesn't specify prerequisites, when not to use it, or how it differs from manually combining sibling tools like vcs_status + install_dependencies.

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