Portable Review AgentNot a PR bot

The Review Agent That Goes Where PR Bots Can't.

Most AI review tools live inside pull requests. MSD reviews code before, during, and after the PR — across GitHub, desktop, terminal, CI, Slack, and WhatsApp — with the same context on every surface.

The Problem

PR bots comment on diffs and stop. Your team reviews software across six surfaces, but the review signal is trapped in GitHub comments that nobody re-reads. Failing checks go unwatched. Stale PRs go unnoticed. Merge readiness is a manual status check.

The Solution

MSD is a portable review agent — one reviewer identity across GitHub, desktop, terminal, CI, Slack, and WhatsApp. It reviews code before the PR opens, delivers specialist feedback during review, and proactively watches checks, surfaces blockers, and tracks merge readiness after. You set the trust boundaries. MSD follows through.

One Agent, Six Surfaces

The same reviewer with the same context, wherever your team works. No re-explaining. No context loss.

Pull Requests

Specialist review agents for security, architecture, and correctness — not generic AI comments. Plus check monitoring and merge readiness tracking.

Desktop

Your review inbox across all repos. See what is blocked, what is failing, and what is ready to merge — without opening GitHub.

Terminal

Same review agent, same context, from the command line. Ask what is blocking a PR or trigger a safe action without leaving your terminal.

CI & Cloud

MSD watches CI pipelines and flags failures as they happen. When policy allows, it suggests or applies fixes so pipelines keep moving without you.

Slack

"What is blocking PR #184?" Get merge readiness, review summaries, and safe follow-up actions from the channel where your team already talks.

WhatsApp

Quick triage from your phone. Check review status, get blocker summaries, and approve safe actions from WhatsApp when you are away from your desk.

Proactive Review Operations

MSD does not wait for you to check. It watches, surfaces, and acts — then asks before crossing trust boundaries.

1

Review Finds You

MSD monitors every connected repo and pushes what needs attention to your review inbox — failing checks, unresolved threads, stale PRs, and new review requests. You see it in desktop, terminal, Slack, or WhatsApp before you go looking in GitHub.

Specialist Depth, Not Generic Noise

Dedicated security, architecture, and correctness reviewers separate must-fix issues from routine noise. Breaking changes and real bugs surface first. Formatting nits and generated-file changes stay out of your way.

Follow-Through, Not Just Feedback

MSD suggests fixes, applies safe changes when policy allows, tracks comment resolution, and monitors merge readiness until the PR lands. It follows through on every review — you set what it can do autonomously and what requires your approval.

What PR Bots Structurally Can't Do

MSD is a portable review runtime, not a comment generator tied to one surface.

Portable Review Runtime

One review agent identity across GitHub, desktop, terminal, CI, Slack, and WhatsApp. Context, history, and prior decisions travel with you. PR bots are locked to one surface — MSD is not.

Run Anywhere — Local, Cloud, or Hybrid

Run reviews on your machine, in your cloud, or both. Your code never leaves your infrastructure unless you choose. No vendor lock-in on where the review agent executes.

Proactive Check Watch

MSD monitors CI pipelines continuously and alerts you across desktop, terminal, and chat the moment a check fails — not when you remember to look. When policy allows, it suggests or applies fixes automatically.

Merge Readiness, Not Manual Status Checks

MSD aggregates approvals, resolved threads, passing checks, and open blockers into a single merge-readiness state. When a PR is ready, it tells you — across every surface. No more manually checking each signal.

Review From Where You Already Talk

Ask from Slack or WhatsApp: what is blocking this PR? Is it safe to merge? What changed since last review? Get answers with full review context — and trigger safe follow-up actions without opening GitHub.

Review Inbox Across Every Surface

One prioritized view of what needs attention across all repos — blocked PRs, failing checks, stale reviews, and merge-ready work. Available in desktop, web, and terminal. PR bots do not give you this because they do not operate outside the PR.

Smart Issue Prioritization

Focus human review time where it matters most. MSD separates must-review issues from routine noise so teams can move with confidence.

Review Without Switching Contexts

Ask a question from desktop. Check a blocker from Slack. Triage a review from WhatsApp. MSD keeps review context intact so you never re-explain across surfaces. When something looks off, ask directly — the agent pulls in history, checks, and comments to give you the full picture.

Context Stays Attached

MSD pulls in history, checks, comments, and prior decisions so review stays intact across desktop, Slack, WhatsApp, and the web.

MSD Review Agent
Tracking PR #184
What is blocking PR #184 from merge?

PR #184 is blocked by one failing integration-tests check and an unresolved security thread on refresh-token storage.

Once the check passes and that thread is resolved, merge readiness goes green. I can summarize the thread or pull the latest failing logs next.

Stop Checking. Start Shipping.
