PR & deploy watcher: reviews, deploy checks, error triage

The payoff

A PR and deploy watcher for a solo developer or a small team. When a pull request opens, it reads the diff and leaves you a short review with the risky lines called out. When a deploy finishes, it checks the live site and the runtime logs and tells you only if something broke. When an error spikes, it builds a triage note with the likely commit. Small, clear fixes get handed to a cloud coding agent that opens a PR. Nothing merges, deploys, rolls back or promotes without you.

What it replaces: refreshing the deploy dashboard after every push, finding out about a broken checkout from a customer, and the context-switch tax of reading every PR cold. Time how often you check your deploy dashboard in a day. That's your baseline.

Who this is for

• Indie developers and small teams shipping on GitHub, with a host like Vercel, who don't have an on-call rotation.
• Anyone already using coding agents who wants a second pair of eyes that isn't the agent grading its own work.

Not for you if you want an autonomous agent with merge rights. This pack is deliberately the opposite. Main stays protected by GitHub itself, not by a promise in a prompt.

How it works

Lane	Trigger	Output
PR review	GitHub: PR opened or updated	Risk summary + blocking issues, in chat
Deploy check	After a deploy (webhook from your CI) or every 2h on weekdays	Silent if healthy; alert with logs if not
Error triage	Sentry event (or webhook)	Likely cause, suspect commit, repro steps
Issue intake	Twice a day	Bug reports from X mentions → deduped GitHub issues
Fix hand-off	You say "fix it"	Cloud coding agent opens one PR

A taste: the rule that makes it safe

From Mike Gannotti's builder/gatekeeper setup (@MichaelGannotti): protect main with GitHub, not with promises. Before you connect anything, turn on a branch ruleset for main in your repo settings:

Require a pull request before merging        ON
Required approvals                           1 (you)
Block force pushes                           ON
Restrict deletions                           ON
Bypass list                                  empty

With that in place, even a confused bot can't push to main. Everything else in this pack is about making the bot useful inside that fence.

Where this comes from

• Builder/gatekeeper split, branch ruleset, "wait for events, don't poll": Mike Gannotti (@MichaelGannotti). Free use-case: /use-cases/builder-gatekeeper-bots-six-rules.
• Draft first. Nothing posts, merges or deploys without you: Paulo (@paulopierrondi).
• X mentions → deduped GitHub issues → small fixes to a coding agent: Emanuele Di Pietro (@emanueledpt).
• Read-only Site Sentry and "hire it like an employee": @zeuss_000. Deploy Watch after every deploy: @igor_khalip.
• Triage bot = skill + computer + plugins: @Lucian_Lc7. Webhook hand-off from coding agents: @sakansokan. One PR, never merged by the bot: @arjunkshah21.
