概要

Add agent-friendly --json NDJSON output to Python CLI scripts, or scaffold a complete cli_utils package for a project. Use this skill when the user wants to make scripts machine-readable for AI agents, add --json flags, convert print statements to structured JSON, build a CLI helper library, create an open-source CLI-for-agents package, add structured logging, or make CLI output machine-readable. Also use when the user mentions NDJSON, structured CLI output, agent-friendly CLI, non-interactive scripts, or JSON I/O for automation.

Agent-Friendly CLI Builder

Convert Python CLI scripts from human-only output to agent-consumable NDJSON, or scaffold a complete cli_utils package ready for open-source distribution.

Two Modes

Mode A: Convert an existing script

When the user points at a script and says "make this agent-friendly" or "add --json":

Scan the script for output points
Generate cli_utils.py if the project doesn't have one
Replace all output with structured helpers
Verify no raw output leaks in JSON mode

Mode B: Scaffold a complete package

When the user says "create a cli_utils package" or wants an open-source library:

Scaffold a full Python package with pyproject.toml, tests, license, README
Include all helpers: json_log, json_error, die, log, add_json_flag, enable_json, is_json
Add pytest test suite with full coverage
Add MIT license (or ask user preference)

Core Architecture

The fundamental pattern: every script gets a --json flag. When active, all stdout becomes newline-delimited JSON (NDJSON). Each line is a self-contained JSON object with a standard envelope.

The NDJSON Event Envelope

Every JSON line has at minimum:

{"event": "ready", "ts": "2026-04-30T14:00:00+00:00", "pid": 1234, "port": 8765}

event — what happened (snake_case string)
ts — ISO 8601 UTC timestamp
Additional fields are event-specific kwargs

Why This Design

NDJSON over JSON arrays: processable line-by-line, one bad line doesn't break the stream, works with grep/jq, low memory for long-running processes
--json opt-in over default: preserves human DX, doesn't break existing scripts or habits
Global mode flag over per-call checks: set once at startup, every helper respects it automatically
die() over repeated if/else: the pattern if is_json(): json_error(); sys.exit(1) else: print(); sys.exit() appears constantly — die() collapses it to one line

The cli_utils.py Reference Implementation

When generating cli_utils.py, produce exactly this (adapt only if the project has specific needs):

"""Shared helpers for JSON CLI output."""
import json
import os
import sys
from datetime import datetime, timezone

_json_mode = False

def enable_json():
    global _json_mode
    _json_mode = True

def is_json():
    return _json_mode

def json_log(event: str, **kwargs):
    """Emit one NDJSON line to stdout."""
    obj = {"event": event, "ts": datetime.now(timezone.utc).isoformat(), **kwargs}
    print(json.dumps(obj, default=str), flush=True)

def json_error(message: str, **kwargs):
    """Emit a structured error event."""
    json_log("error", message=message, **kwargs)

def die(message: str, code: int = 1, **kwargs):
    """Print error and exit — JSON or human depending on mode."""
    if _json_mode:
        json_error(message, **kwargs)
    else:
        print(message, file=sys.stderr)
    sys.exit(code)

def add_json_flag(parser):
    """Add --json flag to an argparse parser."""
    parser.add_argument("--json", action="store_true",
                        help="NDJSON output for agent consumption")

def log(message: str, **json_kwargs):
    """Print human message normally, or emit JSON event if --json is active."""
    if _json_mode:
        json_log(json_kwargs.pop("event", "info"), message=message, **json_kwargs)
    else:
        print(message)

def json_ready(**kwargs):
    """Emit the readiness signal — only in JSON mode. Call early in daemon startup."""
    if _json_mode:
        json_log("ready", pid=os.getpid(), **kwargs)

Converting a Script — Step by Step

Step 1: Scan for output points

Search the target script for all places that produce output or exit:

grep -n 'print(\|sys\.exit\|exit(\|input(\|os\.system.*say' TARGET.py

Categorize each hit:

Informational print → replace with log(message, event="descriptive_name")
Error + exit → replace with die(message)
Status line with \r → replace with if is_json(): json_log("status", ...) else: print("\r...", end="", flush=True)
Interactive input() → guard with if not is_json(): or add --no-interactive flag
Side effects (say, osascript, notifications) → guard with if not is_json():
Import-time errors (before argparse runs) → use sys.exit("message") (writes to stderr)

Step 2: Add the import and flag

At the top of the script, after existing imports:

from cli_utils import add_json_flag, enable_json, is_json, json_log, log, die

In the if __name__ == "__main__" block, add to argparse:

add_json_flag(parser)
args = parser.parse_args()
if args.json:
    enable_json()

Step 3: Replace each output point

Apply the categorization from Step 1. Key patterns:

Simple informational:

# Before
print(f"Connected to {device}")

# After
log(f"Connected to {device}", event="connected", device=device)

Error + exit:

# Before
print("Device not found")
sys.exit(1)

# After
die("Device not found")

Daemon readiness (first output after initialization):

# Before
print(f"Server running on port {port}")

# After — json_ready() only emits in JSON mode, so always call it + human fallback
json_ready(port=port)
log(f"Server running on port {port}", event="ready", port=port)

Status lines (\r overwrite):

# Before
print(f"\r  HR {hr} RMSSD {rmssd:.1f}", end="", flush=True)

# After
if is_json():
    json_log("status", hr=hr, rmssd=rmssd)
else:
    print(f"\r  HR {hr} RMSSD {rmssd:.1f}", end="", flush=True)

Human-only output (banners, usage examples):

if not is_json():
    print("Usage: send {\"type\": \"join\", \"name\": \"Alice\"}")

Step 4: Verify

Run python script.py --help — confirm --json flag appears
Run python script.py --json — confirm first line is valid JSON
Grep for remaining raw print( calls — ensure each is guarded or intentional

Event Name Conventions

Use snake_case, be descriptive, keep them grep-friendly:

Category	Events
Lifecycle	`ready`, `shutdown`, `connected`, `disconnected`
Data	`hr`, `status`, `metric`, `heartbeat`
Errors	`error`, `retry`
Actions	`recording_started`, `recording_stopped`, `preset_change`
Progress	`scanning`, `connecting`, `downloading`, `importing`

Scaffolding an Open-Source Package

When the user wants a distributable package, scaffold this structure:

cli-utils-agent/
├── pyproject.toml
├── LICENSE                  # MIT by default, ask user
├── README.md

    line = capsys.readouterr().out.strip()
    obj = json.loads(line)
    assert obj["event"] == "ready"
    assert obj["port"] == 8765
    assert "ts" in obj

# tests/test_die.py

        assert obj["event"] == "error"
        assert obj["message"] == "something broke"
    finally:
        _core._json_mode = False

Cover: json_log, json_error, die, log, add_json_flag, enable_json/is_json, json_ready.

## Checklist — Run Before Declaring Done

After converting a script or creating a package:

- [ ] `--help` shows `--json` flag
- [ ] Running with `--json` produces valid NDJSON (every line is parseable JSON)
- [ ] First JSON line from daemons has `"event": "ready"`
- [ ] Error paths emit `"event": "error"` with non-zero exit code
- [ ] No raw `print()` can fire when `--json` is active
- [ ] Import-time errors (missing deps) use `sys.exit("message")` not `print()`
- [ ] Interactive prompts are guarded
- [ ] Side effects (voice, notifications) are guarded
- [ ] Human output is preserved when `--json` is NOT passed
- [ ] Unhandled exceptions don't leak tracebacks to stdout in JSON mode (wrap main in try/except, emit json_error)
- [ ] Tests pass (if package mode)
- [ ] Package builds cleanly: `python -m build` (if package mode)
- [ ] Install in clean venv and import works (if package mode)

Dependency or permission surface needs review
Permission surface may require sandboxing
No critical security risks identified. The skill operates on local Python scripts and generates code, but does not execute arbitrary commands or access sensitive data.
The skill does not explicitly mention limitations or safe operating boundaries, though the workflow is well-defined.
Quality score needs review
Permission surface needs review: secrets or environment access, shell or command execution
Dependency/runtime risk: command execution surface, credential or environment access
Permission surface: secrets or environment access, shell or command execution
