👁️ Vigilis

The QA gate for AI-written code.
It heals safe test drift, refuses real regressions, and signs every decision into an independent, verifiable receipt.

The problem

Tell any coding agent to "make CI pass" and the cheapest path to green is deleting the test that caught the bug. AI now writes and fixes tests on its own — so the only question that matters is: can you trust what it did?

Vigilis answers it. Point it at the Playwright, Cypress, or Selenium suite you already have. When a test breaks, it decides:

• Cosmetic drift (a renamed selector) → it heals the locator, re-runs to verify green, opens a PR.
• A real behaviour change (checkout total went from $49 to $0) → it refuses to touch the test, fails the gate, and surfaces the bug instead of burying it.

And every decision is sealed into a signed, offline-verifiable receipt by an independent notary — so a refusal is something you can prove, not just claim.

Self-healing is the wedge. Verifiable proof is the point.

Where teams point it: gate AI-written code · self-heal without hiding bugs · auditable test runs · audit-grade evidence for SOX / payment controls · agent-native (MCP). → see the use cases

See it refuse a real bug

The agent ran the spec, saw it fail, checked that the selectors were all correct, concluded the app's login was genuinely broken, and refused to heal — then sealed a receipt anyone can verify offline.

Quickstart

npm i -D vigilis                      # in your Playwright / Cypress / Selenium project
npx playwright install chromium       # one-time, for browser automation
export ANTHROPIC_API_KEY=sk-ant-...   # a pay-as-you-go API key (not a Claude.ai subscription)

npx vigilis init                                   # scaffold vigilis.config.json (auto-detects your framework)
npx vigilis generate https://your-app.com --run    # explore the app → write + run a real spec
npx vigilis heal https://your-app.com --spec tests/login.spec.ts   # heal drift → verify green → PR (refuses real bugs)

Runs in your CI on your own key + chromium. About 10¢ per run on the fast model (--model claude-haiku-4-5); Opus by default for quality.

Why it's different

	Vigilis
Heals	Rewrites the locator for cosmetic drift, re-verifies green, opens a PR.
Refuses	A real regression is a hard, fail-closed contract — it will not weaken the assertion that caught the bug.
Proves	Every heal and every refusal is sealed into an independent, offline-verifiable receipt (via Treeship).

Attestation is verifiable and auditable — it proves what the agent did, in order, unaltered. It does not claim the agent's judgement was correct. That honesty is the point: Vigilis improves signal, it doesn't hide failures.

Why a refusal is credible: no layer grades its own work. The actor (any agent) writes the code and tests; Vigilis judges the behaviour and gates the deploy; an independent notary (Treeship) signs the verdict. Vigilis never signs its own homework — which is what makes the proof worth anything to someone who doesn't already trust you.

Optional: alert on a refusal

On a real-bug refusal, Vigilis can post a Slack alert and file a deduplicated Linear ticket — each linking the signed receipt. Off by default; a no-op until you set SLACK_WEBHOOK_URL / LINEAR_API_KEY. See docs/REFUSAL-ACTIONS.md.

Drive it from Claude (MCP)

The same tools ship as an MCP server (vigilis-mcp, in the official MCP registry) — generate / triage / heal straight from Claude Desktop, Claude Code, or Cursor. Add it to your MCP client config:

{
  "mcpServers": {
    "vigilis": {
      "command": "npx",
      "args": ["-y", "vigilis-mcp"],
      "env": { "ANTHROPIC_API_KEY": "sk-ant-..." }
    }
  }
}

Full setup: docs/MCP.md.

Provenance receipts

When the Treeship CLI is present, every vigilis heal run is sealed into a signed, offline-verifiable receipt automatically. No hard dependency; --no-receipt to opt out. Verify with treeship verify last. See docs/TREESHIP.md.

Why I built this

I've spent my career in QA, and AI just rewrote the job: agents now write and fix tests on their own. Huge speed win — but it quietly breaks the one thing testing exists for. When an agent makes a red test green, did it fix the bug, or delete the test that caught it? At scale, nobody can check every change by hand.

So Vigilis isn't another self-healer — healing is becoming a commodity. It's the layer that decides honestly which failures to heal and which to refuse, and signs every call so you don't have to take its word for it.

The way I think about it: git is a ledger of your code; Vigilis is a ledger of your agent's decisions — proof you can hand to someone who doesn't already trust you.

How it's built

Vigilis defines its QA tools once and exposes them twice — as an MCP server and as a CLI — over one Claude agent loop:

                     ┌──────────────────────────────┐
                     │   core                       │  Anthropic Messages API + tool use
                     │   Agent loop + Tool Registry │  browser · dom · fs · playwright · git
                     └───────┬───────────────┬──────┘
                ┌────────────▼──┐         ┌──▼───────────────┐
                │ vigilis-mcp   │         │ vigilis (CLI)    │
                │ MCP server    │         │ npx vigilis ...  │
                │ (Claude)      │         │ (used in CI)     │
                └───────────────┘         └──────────────────┘

The loop: Generate (explore a URL → write specs) → Triage (real-bug vs drift vs flake) → Heal (fix drift → verify green → PR, refuse real bugs). Author (plain-English intent → test plan) is on the roadmap.

Repo layout

Develop

pnpm install
cp .env.example .env    # add ANTHROPIC_API_KEY
pnpm build && pnpm test

Roadmap

• ✅ Generate · Triage · Heal (Playwright, Cypress & Selenium — all live-verified)
• ✅ GitHub Actions QA gate · signed provenance receipts · MCP server
• ✅ Refusal actions (Slack + Linear) · governance-cloud audit dashboard
• 🚧 Author (intent → test plan) · broader agent-attestation surface
