voyager-repo

Voyager's repo-penetration organ — the eyes an AI agent sends ahead before it touches an unknown repository.

Voyager penetrates the web (@dir-ai/voyager), the repo (this), and — next — networks. Repotector is the repo's guardian that receives and controls; Voyager Repo is the agent's counterpart that reaches outward and reports back, safely.

npx @dir-ai/voyager-repo scout .          # orient in the repo you're standing in
npx @dir-ai/voyager-repo scout . --check-deps 10   # + vet 10 deps via Voyager

What it does

Like how Claude or Codex orient themselves in a new codebase — but as a safe, repeatable tool. scout produces an orientation brief:

• purpose — inferred from the manifest/README, framed as untrusted (owner text is injection-stripped before it reaches your model)

• structure — languages, key dirs (with role guesses), entrypoints

• build — the install/build/test/run commands (detected, never run)

• health — git signals: commit count, bus factor (top-author share), recency, churn hotspots

• dependencies — composes with Voyager to give each dependency a real OSV-gated verdict (--check-deps N)

• risks — install hooks (RCE on npm install), committed secrets, missing lockfile, large opaque binaries

• approach plan — see below

The approach protocol (the point)

A careful newcomer, not a bulldozer:

1. Handshake with Repotector if the repo carries one (.repotector/) — read its active zones/leases and respect them before editing.

2. Fail-closed permissions. Everything is read-only by default. Installing dependencies, executing code, or cloning a remote is withheld until you consent (--allow-install / --allow-exec / --allow-clone) — and execution, when allowed, belongs in a sandbox.

3. An orderly tour — the brief ends with the ordered next steps a well-behaved agent should take, so it explores on purpose instead of poking at random.

Guarantees

• Nothing in the target is executed on the host. scout reads files and git; it never runs the repo's code. (Execution, when consented, runs in Voyager's hardened container.)

• Every owner-controlled byte is untrusted — README, description, commit messages, the Repotector ledger — injection-stripped and framed before your model sees it.

• Exit codes: 0 oriented · 1 oriented + HIGH-risk finding(s) · 2 tool error.

Tool: scout_repo — same orientation, safe-by-default (invasive flags off).

Library

import { scout } from '@dir-ai/voyager-repo'
const brief = await scout('/path/to/repo', { checkDeps: 10 })
if (brief.risks.some((r) => r.level === 'high')) { /* caution */ }

Status

0.x — Phase 1 (repo orientation) of the Voyager "senses" line. Roadmap: capability analysis of a package's tarball, PyPI/cargo/go dependency vetting, and the net organ (cloud/infra introspection).
