Abbreviated Git Status

Abbreviated Git Status Inspection (git status -s / --porcelain)

Overview

When an autonomous coding assistant executes a standard git status command, Git emits 30 to 80 lines of conversational advice ("On branch main", "Your branch is up to date with 'origin/main'", "use 'git add ...' to include in what will be committed", etc.).

In multi-turn agent loops with frequent state checks, this verbose commentary consumes 500 to 1,500 wasted tokens per turn without adding any actionable file-level information.

The Abbreviated Git Status Protocol enforces the use of git status -s (short format) or git status --porcelain=v1 / v2 - streaming a compact, machine-parseable 2-character matrix that reduces token consumption by 85% while retaining 100% of staging, modification, and branch tracking information.

The 2-Character Status Matrix (XY Format)

In git status -s, the first column X represents the Staging Area (Index), and the second column Y represents the Working Tree:

Automated Agent Execution Recipes

1. Python Subprocess Agent Parser

import subprocess
from typing import Dict, List

def get_compact_git_status() -> Dict[str, List[str]]:
    """Executes porcelain git status and categorizes modified files with zero token bloat."""
    result = subprocess.run(
        ["git", "status", "--porcelain=v1", "-b"],
        capture_output=True,
        text=True,
        check=True
    )
    
    staged, unstaged, untracked, conflicts = [], [], [], []
    lines = result.stdout.strip().split("\n")
    branch_header = lines[0] if lines and lines[0].startswith("##") else "## unknown"
    
    for line in lines:
        if not line or line.startswith("##"):
            continue
        x, y, path = line[0], line[1], line[3:].strip()
        if x == "U" or y == "U":
            conflicts.append(path)
        elif x in "MADRC":
            staged.append(f"{x}: {path}")
        if y in "MD":
            unstaged.append(f"{y}: {path}")
        elif x == "?" and y == "?":
            untracked.append(path)
            
    return {
        "branch": branch_header.replace("## ", ""),
        "conflicts": conflicts,
        "staged": staged,
        "unstaged": unstaged,
        "untracked": untracked
    }

# Example Output:
# {'branch': 'main...origin/main', 'conflicts': [], 'staged': ['M: src/api/auth.ts'], 'unstaged': ['M: src/components/Header.tsx'], 'untracked': ['src/utils/token.ts']}

2. Bash / CLI Agent Tool Wrapper

When crafting commands for terminal execution in tools like run_command:

# Optimal high-signal inspection command
git status -s -b --ignored=no

• -s: Short format (2-column status).
• -b: Shows branch name and tracking status (## main...origin/main [ahead 1]) in 1 line.
• --ignored=no: Suppresses thousands of ignored node_modules and build artifacts.

Agent Operational Directive

MANDATORY: Autonomous coding agents must never run bare git status. Always append -s or --porcelain to keep conversation context windows clean, fast, and token-efficient.
