Nool sits between your coding agents and Git: you decide who may change what, your rules run before anything lands, and every change carries signed evidence.

Coding agents are planes. Nool is air traffic control. Git is the flight log.

Plus d’agents.
Moins de nettoyage.
Des règles appliquées.

Nool se place entre vos agents de code et Git : vous décidez qui peut modifier quoi, vos règles s’exécutent avant tout atterrissage, et chaque changement porte des preuves signées.

Nool은 코딩 에이전트와 Git 사이에 있습니다. 누가 무엇을 바꿀 수 있는지는 여러분이 정하고, 규칙은 변경이 반영되기 전에 실행되며, 모든 변경에는 서명된 증거가 남습니다.

وكلاء أكثر.
إعادة عمل أقل.
قواعد مُطبَّقة.

يقف Nool بين وكلاء البرمجة لديك وبين Git: أنت تقرر من يغيّر ماذا، وتُنفَّذ قواعدك قبل أن يُدمج أي تغيير، ويحمل كل تغيير أدلة موقّعة.

Nothing reaches Git unchecked. Every change takes the same three steps before it reaches Git.

How it works in detail →

CoordinateAgents claim what they will change before they change it.
CheckYour rules run before anything lands, the same way every time.
LandEvery change reaches Git with signed evidence.

Faster source control, same collisions.

Anthropic went from 2,500 to over 30,000 merges a day and rebuilt source control to keep up; OpenAI rebuilt its Git server for Codex. Faster source control doesn't stop two agents from starting work that conflicts.

Without coordination

42–71%

of tokens went to work that never landed.

35 agents on one codebase, unscheduled git

What happens with 35 agents on one codebase using Nool

98–100%

of tasks landed. Same agents, same tickets, same model.

vs 33–62% for unscheduled git

41%

fewer tokens per task landed. Almost nothing has to be redone.

Control

You decide what each agent may change. Agents claim code before they edit it, so overlap shows up first.

Bring your agents. Keep your Git.

Why Nool →

Keep your Git forge. Keep your CI/CD.

Your code stays in Git. Your team keeps its repositories, reviews and CI, so agentic engineering can scale across the company without a migration.

Use the agents you already run: Claude Code, Codex or opencode. Want a harness your team owns? nool code is the one Nool ships, optional and governed the same way.

Enforcement

Tests and policy run before a change lands. A change that breaks them is refused, not flagged afterwards.

Configurable rules. YAML beside the code; edit the file and it applies to the next change.

policies/no_secret_keys.yaml

inv_id: POL-WS-001title: "No secret keys in source code"scope: { type: global }kind: behavioralseverity: criticalmode: blockingreason_code: 403when:  # skip tests: fixtures may hold fakes  not: { semantic_path_is_test: true }forbids:  # refuse AWS access key IDs  - diff_matches: "AKIA[0-9A-Z]{16}"

Hard rules, installed for your teams. Compiled to WASM and sealed; changed only by rebuilding.

fn evaluate(ctx: &PolicyContext) -> PolicyResult {  let changed = changed_paths(ctx);  let has_test = changed.iter().any(|p| p.ends_with(".test.ts"));  for p in &changed {    if p.starts_with("src/billing/") && !has_test {      return PolicyResult::deny(499, format!(        "{p} is billing code: include a test for it in the same change"));    }  }  PolicyResult::Allow}

Security teams ask where the code lives, who signs what, how rules are protected from tampering and what happens if a signing key is compromised. The answers are on one page.
