git_branch_info

Compare the current branch's commits against a base branch, returning repository info as YAML. Resolves remote or local main/master when no base is specified, ideal for reviewing changes without computing an explicit range.

Instructions

Analyze the current branch's commits against a base branch and return repository information as YAML. Use this when you want the diff against main/master (or another base) without computing an explicit range; use git_view_commits instead when you already have a range. Mirrors omni-dev git branch info.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {},
    "name": "git_branch_info"
  }
}

Input Schema

NameRequiredDescriptionDefault
branchNoBase branch to compare against, e.g. `main` or `develop`. When omitted, resolved remote-first: `origin/main`, `origin/master`, local `main`, then local `master`.
repo_pathNoPath to the git repository. Defaults to the current working directory.

TDQS

A4.5/5.0
Behavior4/5

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

No annotations provided, so description carries full burden. It mentions returning YAML and analyzing commits, implying read-only. However, it does not explicitly state non-destructive behavior or permissions. Still, the behavioral traits are reasonably inferred.

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

Conciseness5/5

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

Two sentences plus a note, front-loaded with purpose, no redundant information. Every sentence adds value.

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

Completeness5/5

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

Covers purpose, return format (YAML), use cases, and when to use alternatives. No output schema, but return type is described. Complete for a tool with two optional parameters.

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 coverage is 100% with detailed parameter descriptions. The description adds some context (e.g., branch resolution order) but does not significantly enhance understanding beyond the schema.

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

Purpose5/5

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

The description clearly states the tool's purpose: analyzing the current branch's commits against a base branch and returning YAML. It distinguishes from sibling git_view_commits by specifying when to use each, providing specific verb and resource.

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

Usage Guidelines5/5

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

Explicitly states when to use this tool (diff against main/master without explicit range) and when to use git_view_commits (already have a range). Also references CLI command for familiarity. Clear guidance.

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