Rigour

Your coding agents write code. Rigour makes the codebase learn.

Rigour is a local-first engineering intelligence layer for coding agents. It gives agents the smallest useful context, enforces deterministic boundaries around observable work, and turns verified outcomes into reusable knowledge for the next task.

It is not another chat wrapper or a prettier linter dashboard. Rigour connects code, agent actions, decisions, proof, and learning into one evidence-backed system.

See how agent work improves the codebase

Rigour Studio is an evidence map for engineering work—not just a dependency graph.

intent → context → policy → agent action → verification → outcome → learning

Open Studio to trace an agent run from the recommendation it received to the code it changed, the checks that ran, the risk it prevented, and the knowledge it left behind.

npx @rigour-labs/cli init
npx @rigour-labs/cli hooks init
npx @rigour-labs/cli studio

The five product areas stay simple:

• Map — connect code structure, agent activity, decisions, proof, and outcomes.
• Agents — inspect scopes, run history, handoffs, and the guidance each agent received.
• Review — understand gates, policy decisions, conflicts, and Fix Packets.
• Knowledge — explore patterns, memory, lessons, semantic recall, drift, and cost evidence.
• Settings — see index, graph, cache, learning, storage, and connectivity health.

Start in three minutes

1. Scan a repository

npx rigour-scan

Rigour runs local quality, security, and AI-drift checks and returns an actionable result.

2. Add the Rigour loop

npx @rigour-labs/cli init
npx @rigour-labs/cli hooks init --tool cursor
npx @rigour-labs/cli skills install --target codex,cursor
npx @rigour-labs/cli check

hooks init supports Cursor, Claude Code, Cline, and Windsurf. It checks observable writes as agents work; check is the full project verification step.

3. Give every agent the same good workflow

rigour skills install --target codex,cursor

Rigour Skills turn its evidence loop into small, reusable agent workflows:

• rigour-context asks for the smallest explainable scope before an agent reads code.
• rigour-verify closes a change with proof and a Fix Packet repair loop.
• rigour-handoff transfers verified state without replaying an entire session.
