Agent Native 1.0.0

The first stable release. Stability lists the eleven stable entry points covered by semver and the experimental ones that are not. Upgrading from 0.1.x covers every change below. See the 1.0.0 changelog.

• npm run check:api guards the declarations of every stable entry point against api/stable-api.txt.
• Breaking: @uppercut-labs/agent-native/mcp no longer exports the MCP Apps plumbing. Use @uppercut-labs/agent-native/mcp-apps.
• Behavior change: with bearerAuth and no public-read capability, a request without a token gets a 401 challenge instead of an empty tool list. bearerAuth.required controls this.
• Bindings receive the authorized caller as context.caller, including the verified identity.
• MCP adapters gain onToolFailure and toolName.
• The Zod peer accepts ~4.6.5.
• npm run check passes on Windows 11 with npm 12.

These changes come from the first real integration, Domain Expansion. It serves its records to Claude Code over remote MCP on Cloudflare Workers.

Agent Native 0.1.3

Documentation and example-reliability release. The package's own source and API are unchanged from 0.1.2. See the 0.1.3 changelog.

• The packaged host evidence records that both Claude Code 2.1.286 and Antigravity CLI invoked the flagship E04 tool over remote MCP. It also records the verified 0.1.2 npm publication.
• The E05 example server installs its signal handlers before announcing readiness, and its host test always cleans up spawned servers. The example is not included in the npm package.

Agent Native 0.1.2

Native WebMCP interop fix, a commercial agent-host probe, flagship CLI and E12 server parity, out-of-repository example checks, and the TypeScript house-style pass. Node.js 22+. See the 0.1.2 changelog.

Highlights

• Browser WebMCP tools send the draft's consequentialHint for destructive capabilities. E06 and E01 were verified in Chrome 155 with the opt-in WebMCP feature.
• Antigravity CLI invoked the flagship E04 album tool over remote MCP.
• E04 has a remote CLI over the shared flagship contract, and E12 adds a server binding with HTTP parity tests.
• npm run check:isolated-examples installs and tests all twelve exports outside the repository.
• src follows the TypeScript house guide; exported signatures are unchanged.

Agent Native 0.1.1

Local Codex programmatic sessions using existing managed ChatGPT sign-in, explicit model selection, same-thread resume, targeted interrupt and owned process cleanup. Includes isolated neutral contracts and a loopback MCP bridge that preserves application authorization. Node.js 22+; no optional provider SDK required for the harness exports.

Installation

@uppercut-labs/agent-native@0.1.1 is published and npm latest resolves to 0.1.1. Install with npm install --save-exact @uppercut-labs/agent-native@0.1.1. Initial unauthenticated publication failed; subsequent authenticated publication and fresh registry acceptance succeeded.

The GitHub archive remains a fallback. Download both assets, run shasum -a 256 -c uppercut-labs-agent-native-0.1.1.tgz.sha256 (Linux: sha256sum -c), then install the verified archive into the intended project with npm install ./uppercut-labs-agent-native-0.1.1.tgz.

SHA-256: a1ce884f89eadba319d6fbad5c9b09b05575a7ab15998bcfd4a6ad8cc8228fbb
Archive: 168772 bytes, 152 files. Source: ab79aed4b8556752b33286f2edf261a07b3921d1; its tree matches reviewed candidate 012a830.

Validation and limits

Full checks passed: 130 package tests, all twelve independently installed examples, types/browser boundaries, docs and optional-peer-free packed consumers. Node 22/24 CI passed on the exact candidate. Independent focused synthetic verification passed all 15 harness/bridge tests. Source and predecessor fresh-tarball Luna two-turn file verification, same-thread cross-process resume and cleanup passed; release workflow acceptance is recorded in the reusable skill release.

Codex local is supported by this preview. Cursor, cloud and programmatic Codex MCP configuration remain deferred. Existing Codex configuration still applies. The bridge does not grant capability permissions or open a public tunnel. No provider secrets, account identities or raw transcripts are included.

Released-archive acceptance

Verified 2026-10-05T04:57:41Z using the public GitHub downloads and matching SHA-256 sidecars. Fresh bundled skill installation preserved project dependency metadata and added no project runtime packages; Codex app-server discovered the enabled repo skill without discovery errors. After separately installing the released adapter, the installed reusable proof passed both exact file checks, same-session resume through a fresh process and owned cleanup with Node 24.19.0, Codex CLI 0.145.0, gpt-5.6-luna / low and managed ChatGPT sign-in. No raw provider or account output is included. This is local-route evidence only.

Registry acceptance - 2026-10-05

Both registry downloads match the released archives byte-for-byte and by SHA-256/SHA-512 integrity; npm latest is 0.1.1 for both packages. A fresh npm cache/consumer installed the skill through the public registry without changing dependency metadata or creating project runtime packages, and actual Codex discovery passed. Separate npm adapter installation, optional-peer-free root/browser/Codex imports and missing-runtime guidance passed without further inference.
