auto-yes 0.13.0

Automatically respond 'yes' to interactive CLI prompts via PTY proxy

auto-yes

Auto-respond to AI CLI prompts. Never get blocked by interactive yes/no dialogs again.

auto-yes wraps any CLI command in a PTY (pseudo-terminal) proxy, watches the output stream for interactive prompts and automatically injects the correct response — so your overnight AI agent loops, CI scripts, and automation pipelines never block waiting for a human.

Works out-of-the-box with Claude Code, Cursor Agent, Gemini CLI, OpenAI Codex, GitHub Copilot, Amazon Q, Aider, and 10+ more AI CLI tools. Also handles generic [y/n], Continue?, SSH fingerprint, Terraform yes, and any custom regex you define.

Installation

pip install auto-yes

Windows users — for full PTY support add the optional extra:

pip install auto-yes[windows]

Quick start

Wrap an AI CLI tool directly (recommended)

auto-yes claude "fix the tests"          # wraps: claude "fix the tests"
auto-yes cursor chat "add unit tests"    # wraps: agent chat "add unit tests"
auto-yes gemini "review this PR"         # wraps: gemini "review this PR"
auto-yes codex "explain this function"   # wraps: codex "explain this function"
auto-yes aider --model gpt-4o           # wraps: aider --model gpt-4o
auto-yes copilot                         # wraps: gh copilot
auto-yes amazonq chat "help me"          # wraps: q chat "help me"

The profile name maps to the real binary automatically — run auto-yes list to see all profiles.

Overnight / automation mode (--auto)

For unattended overnight runs in corporate environments where --dangerously-skip-permissions is restricted:

# load ALL AI profiles, near-zero cooldown (0.05s), verbose logging
auto-yes run --auto -- claude --dangerously-skip-permissions "work through the backlog"

# or pipe through a loop
for task in tasks/*.md; do
    auto-yes run --auto -- claude "$(cat $task)"
done

--auto automatically:

• Loads patterns for all supported AI CLI tools
• Sets cooldown to 0.05s (fast batch mode)
• Enables verbose logging so you can audit what was approved

Shell session mode

Start a persistent shell where every prompt is auto-answered:

auto-yes --on --cli claude
# → now inside an auto-yes session; type normally, prompts are handled
exit

Single-command mode

auto-yes run -- apt install nginx
auto-yes run --cli claude --cooldown 0.2 -- claude "fix tests"
auto-yes run --cli all -- ./deploy.sh   # match every AI tool + generic

Session management

auto-yes status            # check if active in current shell
auto-yes ls                # list all running auto-yes sessions
auto-yes pause <pid>       # pause a session (prompts pass through)
auto-yes continue <pid>    # resume a paused session

Anti-false-positive safeguards:

Guard	What it prevents
Typing suppress (1 s)	User's own keystrokes triggering auto-responses
Match cooldown (0.05 s)	Terminal redraws re-triggering the same prompt
Response cooldown (0.5 s default)	Rapid-fire duplicate responses
Bottom-up line scan	Matching stale text buried in scrollback
Buffer clear on input	Stale prompt text re-matching after user interaction

Multi-agent & parallel agent scenarios

auto-yes is designed for multi-agent orchestration where multiple AI agents run concurrently and each may trigger prompts:

# 5 parallel Claude Code subagents — auto-yes handles all prompts
auto-yes run --auto -- orchestrator --agents 5 --task "migrate database schema"

# Overnight loop: run until complete, auto-approve every permission
while true; do
    auto-yes run --auto -- claude "continue where you left off"
    sleep 60
done

Tested with 5 simultaneous agents, 10-iteration overnight loops, interleaved Claude + Cursor prompts, and 1 000+ rapid sequential approvals.

Python API

from auto_yes.runner import Runner
from auto_yes.patterns import get_command

# wrap claude with all its patterns
runner = Runner(
    categories=["claude"],
    cooldown=0.1,
    verbose=True,
)
exit_code = runner.run_command(["claude", "fix the tests"])

# generic patterns for any command
runner = Runner(categories=["generic"], response="y")
exit_code = runner.run_command(["apt", "install", "nginx"])

# custom extra pattern on top of a profile
runner = Runner(
    categories=["cursor"],
    extra_patterns=[r"deploy to production\?"],
)
cmd = get_command("cursor")   # → ["agent"]
exit_code = runner.run_command(cmd + ["chat", "deploy the app"])

Configuration

Stored at ~/.config/auto-yes/config.json (Linux / macOS) or %APPDATA%\auto-yes\config.json (Windows):

{
  "custom_patterns": [],
  "response": "y",
  "cooldown": 0.5,
  "verbose": false
}

Adding a new AI CLI profile

Add one entry to REGISTRY in src/auto_yes/patterns.py:

_MY_TOOL = {
    "description": "My AI Tool CLI",
    "command": ["my-tool"],              # real binary (list of strings)
    "patterns": [
        (r"approve action\?", None),     # None → use default response ("y")
        (r"type yes to confirm", "yes"), # explicit response string
    ],
}
REGISTRY["my-tool"] = _MY_TOOL

No other file needs to change. Run auto-yes list to verify it appears.

---
