MergeWarden v0.4.0 Release Notes
MergeWarden v0.4.0 renames the project from Agent Gate and publishes the CLI
under the unscoped npm name mergewarden. The GitHub repository is now
sjh9714/mergewarden; old repository URLs redirect. The scoped package
@jinhyuk9714/agent-gate remains at v0.3.1 and is deprecated.
Try It
npx --yes mergewarden@0.4.0 scan owner/repo#123The CLI analyzes public pull requests without cloning, checking out,
installing, or executing target-repository code. Private repositories and
higher GitHub API limits use GH_TOKEN, with GITHUB_TOKEN as the fallback.
Highlights
- Rename the base-branch policy file to
mergewarden.ymland the PR body
contract marker tomergewarden-contract. This is a clean break with no
compatibility alias; see the v0.4.0 migration guide. - Rename default report outputs to
mergewarden-report.jsonand
mergewarden-report.md. Finding IDs keep theagf_prefix so existing
waivers remain valid. - Reposition the README around agent-specific boundaries: declared PR scope,
agent-control-plane drift, and agentic workflow injection. - Add integration guides for gating Claude Code
and Codex pull requests. - Publish the AI-agent PR scan methodology used for the
v0.4.0 launch study.
The signed v0.3.x tags remain immutable. v0.4.0 is a new source, tarball, and
provenance identity under the MergeWarden name.
