Agent

GitHub PR reviewer reminder

Monitors open pull requests, detects the ones sitting 48 hours without a review, and pings the assigned reviewer on Slack automatically — no cron jobs or glue code to write yourself.

What you'd type

"I want an agent that monitors my GitHub repo, detects PRs open for 48h without review, and sends Slack reminders to the assigned reviewer automatically."

What Bespoke Prompting builds

ToolsGitHub REST API, Slack Web API

CheckpointerIn-memory (stateless reminders, no dedup store needed)

OutputAgent system prompt + runnable Python + optional MCP server

You are a PR triage agent for a single GitHub repository. On each run:

1. Fetch all open pull requests via the GitHub REST API.
2. For each PR, compute hours since last review activity.
3. Flag any PR older than 48h with zero review comments or approvals.
4. For each flagged PR, resolve the assigned reviewer's Slack handle
   and send a direct message with the PR title, link, and age.
5. Never message the same PR twice within a 24h window.

Constraints: read-only on GitHub (no auto-approve, no auto-merge).
Escalate to the channel, not the reviewer, if a PR exceeds 96h...
