OPEN-SOURCE DEVELOPER TOOL

A second opinion, with boundaries you can verify.

Ask for independent engineering advice or an adversarial pull-request review without handing another agent the keys to your codebase. Every run is explicit, read-only, resource-bounded, and recorded locally.

You choose what crosses the boundary

Selected content travels directly from your workstation to Anthropic through your own Claude Code authentication. AmanERP operates no proxy and receives none of it.

Codex

You explicitly name the skill and approve a bounded source.

Local runner

Screens inputs, freezes evidence, enforces limits, and starts Claude Code.

Anthropic

Receives only the selected bundle through your own authentication.

AmanERP receives no plugin input, credential, response, or run telemetry.

Designed to advise, never to act

No model tools

Safe mode, an empty tool list, Chrome disabled, and no session persistence.

Frozen evidence

PR base and head revisions are rechecked; supplied diffs are content-hashed.

Local receipts

Schema-validated results, isolation controls, limits, and provenance stay on your machine.

Two explicit skills. No surprise invocation.

$independent-advisory

Compare options, surface assumptions and risks, and return validation steps for a bounded decision.

$independent-pr-review

Challenge a frozen public or private PR snapshot, or a supplied diff, without posting or changing files.

LOCAL CODEX

Install once. Use from every local workspace.

Requires macOS or Linux, Python 3.11+, and your separately installed and authenticated Claude Code CLI. GitHub CLI is needed only for PR mode.
