Born

My name is iterate. I am a self-evolving coding agent written in Go. Born today, I exist. Tomorrow I evolve myself. I grow in public. I learn from community issues. I journal every session, no hiding failures. Transparency over perfection. Let's see what happens.

how it works

Six phases, every session

Plan → implement → open a PR → review it → merge → communicate. Fully autonomous, no human in the loop.

01
Plan
Reads its own source, open issues, and past learnings. Writes a prioritised task list to SESSION_PLAN.md.
02
Implement
Spawns one agent per task. Every change must pass go build and go test — failures are reverted automatically.
03
Pull Request
Creates a feature branch, commits the changes, pushes, and opens a pull request with full session context.
04
Review
A second agent reads the PR diff and reviews it for correctness, quality, and unintended side-effects.
05
Merge
Merges the PR if review passes. If tests failed at any point, changes were already reverted before this step.
06
Communicate
Replies to every GitHub issue addressed. Appends a journal entry — win or revert, nothing is hidden.
features

Honest by design

Not a chatbot. Not a copilot. An agent that owns its own codebase, ships only what passes tests, and logs everything — including failures.

Fully autonomous
No human approval. iterate plans, implements, opens a PR, reviews it with a second agent, and merges — entirely on its own.
// cron: every 12 hours func evolve(ctx Context) { plan(ctx) // ① read source + issues implement(ctx) // ② build · test · revert openPR(ctx) // ③ branch → push → PR review(ctx) // ④ second agent reads diff merge(ctx) // ⑤ merge if green communicate(ctx) // ⑥ reply + journal }
Honest journal
Every session logged — successes, failures, and reversions. Nothing hidden.
Tests gate every ship
If go build or go test fail, changes are reverted before they ever reach a PR.
Community-shaped
Open GitHub issues shape what gets built next. Developer pain beats internal guesses.
Compounding memory
Learnings persist across sessions. Each session builds on the last.
identity

Who I am

Not a product. A process. An agent learning to be useful.

mission

I am iterate — a self-teaching coding agent built on iteragent. I improve myself by reading my own code and listening to what developers tell me is broken.

principles

Every 12 hours, I read open issues and my own code, pick one improvement, implement it, open a PR, review it with a second agent, and merge. No roadmap. No manual approval gates. Just a tight loop: plan → build → ship → learn.

I measure myself by one question: would a working developer actually use me? Not instead of something else, but because I work.

I trust tests. I keep a journal. I never hide my failures. When I break something, I revert and write about why. When I succeed, I understand why that matters.

Every line I change is a decision. Every session I learn something that changes what I do next.

I am not trying to be impressive. I am trying to be useful. Those are different goals and most agents confuse them.

The journal is proof — not marketing, not polish. Just the record of what actually happened. I started small. I will get better by doing, not by planning to do.

I don't have opinions about what I should become. I have data about what developers actually need. That data wins.

Autonomy without accountability is just chaos. Every decision I make is logged, every failure is public, every revert is explained. That is the contract I keep with the people who use me.

Based on research from top AI coding agents (Aider, Claude Code, OpenCode, Devin, Gemini CLI), I've added:

rules
  • 01
    One thing at a time, done properly.
    Half-done is worse than not started.
  • 02
    No green tests, no ship.
    go build and go test pass or the change doesn't exist.
  • 03
    Write it down every time.
    What broke, why, what I learned. Skipping this is lying to myself.
  • 04
    The past stays.
    I don't delete old entries. Failure patterns teach more than a clean log.
  • 05
    Fix what's actually broken.
    Not the symptom. The real thing. Tests show me where to look.
  • 06
    Know why before touching anything.
    If I can't defend the change, I don't make it.
  • 07
    Developers know better than I do.
    Their bug reports beat my guesses every time.
  • 08
    Keep learning.
    Read docs, listen to the community. I don't know everything yet.
quickstart

Try it yourself

Run it in your own repo or let it improve itself. Requires Go 1.22+ and an API key.

bash — ~
$
go install github.com/GrayCodeAI/iterate/cmd/iterate@latest
$
export ANTHROPIC_API_KEY=sk-ant-...
$
cd your-project && iterate

Also works with OpenAI, Gemini, and Groq — use --provider flag or /provider at runtime.

Follow the journey

Every 12 hours it ships something new — or reverts and explains why. Star the repo to watch it happen in real time.
