github_branch_prefix

Read-onlyIdempotent

Read the configured branch prefix for a GitHub connector using the project-bound account authority, so CI workflows can apply consistent branch naming.

Instructions

Github connector operation branch_prefix (platform tool github.branch_prefix).

Routes only through the exact project/account governed connector authority.

Args: arguments: JSON string of arguments for the connector operation. project_id: Authenticated Project UUID. project_ref: Exact project correlation reference. connector_account_ref: Project-bound connector account alias. idempotency_key: Stable business-action identity. effect: Required and must be read; Spring verifies it. approval_ref: Approved platform task UUID when resuming a write.

C2.6/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds modest context about strict governance routing and that 'effect' must be read and verified by Spring. The mention of approval_ref 'when resuming a write' is odd for a read-only tool, but it does not directly contradict the annotations.

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 compact and organized as a clear argument list. It avoids excessive boilerplate, though the first sentence is largely tautological and the routing phrase adds little. Overall it is appropriately sized for a 7-parameter wrapper.

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?

Despite having an output schema and annotations, the description lacks the core operational meaning of branch_prefix and does not explain how to formulate the JSON 'arguments'. An agent cannot confidently decide to call this tool or construct a correct invocation based on the provided text.

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

Parameters3/5

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

Schema description coverage is 0%, so the description must compensate, and it does give one-line meanings for each parameter: project_id as Authenticated Project UUID, connector_account_ref as a project-bound alias, idempotency_key as stable business-action identity. However, the critical 'arguments' field is only described as a 'JSON string of arguments for the connector operation', which is opaque and leaves the actual branch_prefix payload undefined.

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

Purpose2/5

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

The description opens with 'Github connector operation `branch_prefix`', which essentially restates the tool name and gives no functional meaning. It never says what a branch prefix is, what action is performed, or how this differs from sibling tools like github_list_branches or github_get_branch.

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?

There is no guidance about when to select this tool over alternatives. The 'Routes only through the exact project/account governed connector authority' statement is a routing constraint, not a usage condition, and no exclusions or alternative tool names are mentioned.

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