gate

One ship/no-ship verdict from your whole nugehs toolchain.

gate runs aiglare, bouncer, tieline and repoctx against a repo and merges their four dialects into one normalized verdict. Each tool already answers a different "can this ship?" question — gate is the place they finally agree on the answer.

npx @nugehs/gate                      # audit the current repo
npx @nugehs/gate ./service --ci       # fail the build on a blocking verdict
npx @nugehs/gate --json               # the unified verdict, machine-readable

What it reports

  gate · /path/to/repo

  ✗  AI governance    fail      2 red · 1 amber · 13 green · 1 blocking side-effect
  ·  Compliance       skipped   not configured (run `bouncer init`)
  ·  Contract drift   skipped   not configured (run `tieline init`)
  ⚠  Merge readiness  warn      1 of 8 checks need attention

  verdict: FAIL — 1 blocking · 1 warn · 2 skipped

Each tool's native result is normalized onto one status vocabulary:

The top-level verdict is the worst across the domains that actually ran (skipped never counts). unknown and error roll up to warn so nothing slips through as a silent pass.

How each dialect maps

gate runs aiglare without --ci and derives the blocking verdict itself, so a tool that process.exit()s before flushing its pipe can't truncate the report it feeds us.

A run that checked nothing is not a pass. If every domain is skipped or deselected (e.g. --skip them all, or a typo'd --only), gate reports NO CHECKS RAN (ok:false) and fails under --ci — a misconfiguration can't silently turn the gate green.

On repoctx + local mode. repoctx's merge-readiness gate can only verify review state (approvals, CODEOWNERS, required checks) against a host like GitHub. Run locally it reports those as a WARN, so on a clean local repo gate will often show merge readiness: warn. That's repoctx being honest about what it can't see locally — not a problem with your change.

CLI

gate [path] [options]

  --json            Emit the unified verdict as JSON
  --ci              Exit non-zero when the gate fails (blocking by default)
  --strict          Treat WARN/UNKNOWN as blocking too
  --only <list>     Run only these tools (aiglare,bouncer,tieline,repoctx)
  --skip <list>     Skip these tools
  -h, --help        Show this help

gate mcp            Start the MCP server (stdio)

By default only a fail verdict blocks under --ci — safe to adopt without drowning a team in warnings. Add --strict when you want warnings to gate too.

Tool resolution

gate doesn't bundle the four tools; it finds each one at runtime. Per tool, first hit wins:

1. GATE_<TOOL>_BIN environment variable (explicit override)

2. the installed @nugehs/<tool> package (from node_modules)

3. a sibling checkout at ../<tool> (local development)

A tool that can't be resolved is reported as skipped, never a hard failure — so gate is safe to run in a repo that only uses some of the toolchain.

In CI

- run: npx @nugehs/gate . --ci

For a machine-readable record, --json emits the full verdict (schema version, per-domain results, counts, and the blocking reasons) for dashboards or audit evidence.

MCP

gate is also an MCP server, so an agent can ask "can this ship?" in one call — the unified verdict, not four separate tools.

gate mcp                 # stdio JSON-RPC server
npx @nugehs/gate mcp

Tools:

Registry manifest: server.json (io.github.nugehs/gate).

Editor extension

The same normalized verdict drives a VS Code / Cursor extension (clients/vscode) — the gates, shifted left from CI into the editor:

• a verdict cockpit and a checks tree in gate's own Activity Bar container;

• inline diagnostics, hovers, Quick Fixes (mute / open docs) and CodeLens on located findings;

• AI-native gating — an @gate chat participant, a gate_check tool agent mode can call before it says "done", and an MCP server provider — so the assistant writing the code is checked by the same gate as CI;

• debounced run-on-save with in-flight cancellation, and multi-root support.

Roadmap

gate is the shared spine. The same JSON already drives the CLI, the --ci gate, the MCP server, and the editor extension above. Next client on the same JSON:

• Web cockpit — a repo/PR verdict board over the JSON, unifying the four *-web sites.
