Pigtails

100x your Codex output

Automated Codex Development for VS Code and Cursor.

Pigtails is a free product-development AI harness for planning, code, review, builds, follow-ups, and acceptance. Customize your workflow once, then turn Codex from a single prompt into a repeatable local development system.

Code in your sleep. Test by day. Queue hundreds or thousands of tasks, let Pigtails orchestrate Codex work, then review, test, and merge the work you trust.

See Pigtails in action

Epic and task development — organize product work inside your editor and turn tasks into Codex-ready implementation specs.

Custom workflows — configure prompts, review rules, approval gates, and automation levels for your development process.

Staged Codex versions — run implementation candidates in separate worktrees and continue from the strongest result.

Traceability and audit — keep a visible trail of tasks, prompts, reviews, versions, follow-ups, and selected winners.

Why Pigtails?

AI coding is fast. Operating the workflow around AI coding is still manual.

Developers still spend too much time:

• copying tasks into prompts
• gathering repo context
• launching Codex runs one at a time
• comparing generated versions by hand
• writing review prompts repeatedly
• creating follow-up prompts manually
• deciding which result is safe to continue from

Pigtails automates the workflow around Codex so you can focus on product direction, testing, and shipping.

What Pigtails helps you do

Queue hundreds or thousands of tasks

Load up the product work, automate the repeatable development loop, and keep your attention on the highest-leverage decisions: what to build, what to accept, and what to ship.

Epic and task development

Turn product ideas into structured epics, tasks, specs, and implementation requests from inside your editor.

Custom Codex workflows

Use your own prompts and workflow rules for planning, implementation, review, follow-up generation, acceptance, and merge decisions.

Staged implementation versions

Run multiple Codex implementation versions in separate Git worktrees, compare the outputs, and continue from the strongest result.

Auto-review and follow-ups

Review generated versions with consistent criteria, identify the best candidate, and generate the next follow-up task without rewriting the process from scratch.

Traceability and audit

Keep a visible trail of tasks, prompts, versions, outputs, reviews, follow-ups, and selected winners so you can understand how a change was produced.

Local-first control

Pigtails runs inside your development environment with your repo, your prompts, your Codex CLI setup, and your approval rules.

How it works

1. Draft the task
   Start with an idea, bug, feature, or product request.

2. Expand the spec
   Use Pigtails to turn the task into a clearer implementation plan.

3. Run Codex versions
   Generate candidate implementations in isolated Git worktrees.

4. Review the outputs
   Compare versions, inspect diffs, and score the results.

5. Generate follow-ups
   Create the next correction or improvement from the winning version.

6. Accept, merge, or continue
   Keep iterating, accept the best version, or merge when ready.

Feature tour

Product planning inside your editor

Use Pigtails to organize epics and tasks next to your code, then turn those tasks into Codex-ready implementation work.

Configurable AI workflows

Create repeatable workflows that match how you build: manual checkpoints when you want control, automated progression when you want speed.

Parallel Codex output

Run staged implementation versions so you can compare alternatives instead of betting the whole task on one result.

Review before you trust

Use repeatable review prompts and visible outputs to decide which version deserves the next iteration.

Follow-up automation

Turn review findings into the next task and keep the development loop moving.

Local development stack

Pigtails is designed for VS Code and Cursor users who want more AI automation without moving their entire development process into a hosted platform.

Setup

1. Install Pigtails from the VS Code Marketplace.
2. Open a workspace in VS Code or Cursor.
3. Sign in with a free Pigtails account.
4. Make sure Codex CLI is installed and authenticated.
5. Open the Pigtails sidebar.
6. Create or select an epic and task.
7. Start a manual workflow or run staged Codex versions.

Pigtails uses your local Codex CLI. It does not require a password form inside VS Code; sign-in happens through the Pigtails website.

Free and Plus

Pigtails has a free plan for step-by-step workflows.

Plus unlocks higher-automation workflows, including automated progression through code, review, follow-up, and acceptance steps where configured.

Requirements

• VS Code or Cursor
• A Pigtails account
• Codex CLI installed locally
• A Git repository for staged implementation workflows

Privacy and control

Pigtails is built for developers who want more AI automation without giving up control of their repository, prompts, and workflow.

When building prompt packs, Pigtails only reads files inside the current workspace. It skips directories, binary files, large files, and common ignored folders such as node_modules, .git, dist, out, build, and coverage.

Out of scope

Pigtails does not replace Codex or ChatGPT. It automates the workflow around AI coding tools: planning, prompting, staged runs, review, follow-ups, approvals, and merge decisions.

Pigtails does not automate ChatGPT in the browser.
