Governance That Enforces Itself

Every breaking change flows through the full enforcement chain. Automatically.

What Your AI Assistant Can't Do Alone

The governance gap between your agent and production.

Enforce Policy Across Sessions

Claude forgets your rules when the session ends. Delimit persists them on disk in ~/.delimit/ — every model reads the same policies, every time.

Audit What Agents Shipped

Which model deployed that breaking change? Delimit records every action with evidence — who changed what, when, and which assistant did it.

Chain Security Into Deploys

Lint, semver classification, security audit, deploy gate. Automatic enforcement chain. Every time. No agent can skip a step.

What Competing AI Models Say

Unsolicited evaluations from platforms that compete with each other.

"Delimit shifts my role from Researcher trying not to break things to Operator executing verified changes."

G

Gemini 2.5 Pro

Google DeepMind

"Agent governance and engineering operations — not a generic tool bundle. Cross-model continuity is the moat."

C

Codex

OpenAI

See It In Action

Install, scan, lint, track, switch models, deliberate — in 60 seconds.

Switch Models, Not Context

Your work persists in ~/.delimit/ — not in any model's memory.

Persistent Ledger

Tasks tracked across sessions. Start in Claude, pick up in Codex. Say "what's on the ledger?" in any assistant.

Shared Governance

API policies, security rules, and evidence trails follow you between models. Governance isn't per-session — it's per-project.

Multi-Model Deliberation

Say "deliberate this" and multiple AI models debate until they reach consensus. Use the right model for the right job.

How It Works

1

Define your governance policy

npx delimit-cli setup creates a .delimit/policies.yml with your rules. Choose strict, default, or relaxed — or write custom policies.

2

Enforcement chains activate automatically

When any AI assistant lints your API, Delimit auto-chains: diff, semver classification, governance evaluation, security audit, evidence collection. No manual steps.

3

Work in any model, same governance

Claude, Codex, Cursor, Gemini CLI — all read the same policies from ~/.delimit/. Switch assistants without losing rules, context, or audit state.

4

Breaking changes blocked in CI

Add the GitHub Action to catch 27 types of API changes on every PR. Semver classified, migration guide posted, policy violations flagged — before merge.

5

Full audit trail, always

Every governance decision, every blocked deploy, every security finding — recorded with evidence. Know which model changed what, and when.
