AI makes waves.
jKeel keeps you steady.

The safe AI harness for Java teams: the rules, permissions, automatic checks and review steps that let you use an AI coding agent on a real codebase without lowering quality.

Your team wants AI. Your organisation is careful.

Government, banks and insurers have good reasons to be cautious. The answer is not to ban AI agents, but to put a keel under them.
  • Agents act fast
    An AI coding agent can delete files, push to main or open a secrets file in seconds, long before anyone reviews it.
  • Rules are only advice
    A rules file tells the agent what you want. Nothing stops it when it gets that wrong. A harness adds checks that do.
  • Skills are unproven
    Skills are instruction packs you add to an agent. They are free everywhere, but almost nobody measures whether one helps.
First release · free

A template repo you can copy

We are building the first piece now: a free, open-source template with everything a team needs to start safely.
Team rules
Ready-made rules files (CLAUDE.md and AGENTS.md) written for Java and Spring Boot projects.
Safety hooks
Small scripts that check each agent action before it runs. They block deleting files outside the project, pushing to main, touching secrets and editing CI or build credentials.
Safe permissions
A safe default: the agent starts read-only. Guarded edits are the second step, when your team is ready.
Review check
A CI check that flags AI-written changes, so a person always reviews them before they merge.
One tested skill
One skill, plus a simple way to test it: run the same tasks with and without the skill and compare the results.

Steady, not slow

A keel keeps a boat on course without slowing it down. That is the idea behind every choice we make.
  • Nothing leaves your environment
    The template is plain files in your own repository. It runs inside your own AI agent and sends nothing to us.
  • Open source
    Read every rule and every hook before you use it. No black box between your team and your code.
  • Made for Java teams
    Java 21 and up, Spring Boot and Maven first. Gradle support comes later.
  • Honest about limits
    Hooks are a seatbelt, not a sandbox. We say what they catch, what they miss and what you still need, such as branch protection.

Nothing to install yet
