Continuous QA agent that runs persistent test loops, evolves test plans with the code, and sends real-time progress notifications via Telegram.
Overview
Sentinel is the continuous testing agent that never sleeps. Unlike one-shot test runners, Sentinel operates in persistent loops — testing your application repeatedly, tracking test health over time, and catching regressions the moment they appear.
Sentinel maintains a living test plan that evolves with your codebase. When you add new features, Sentinel automatically discovers them and adds them to its test matrix. When you fix bugs, it adds regression checks to ensure they never return. The test plan grows smarter with every cycle.
Each test run creates a checkpoint, allowing Sentinel to resume from where it left off if interrupted. Historical results are preserved, giving you trend data on application stability across releases. Sentinel sends real-time notifications via Telegram as it progresses through test phases.

Process
Sentinel follows a systematic process to deliver consistent, high-quality results.
Reads your README, user stories, and feature documentation to build a comprehensive test plan covering all described functionality.
Executes tests in phases (INIT → RECON → TEST → FIX → VERIFY → COMPLETE), saving progress after each phase for resumability.
Runs test loops on a schedule, comparing results across runs to detect stability trends and emerging regressions.
When bugs are found, Sentinel fixes them automatically, runs verification tests, and commits with detailed fix descriptions.
Use Cases
Run comprehensive tests every night and receive a morning report showing exactly what broke, when, and in which commit.
After every deployment, Sentinel verifies all critical paths work in production and alerts immediately if anything fails.
Run full regression tests on feature branches before merge to catch issues early, when they're cheapest to fix.
Run Sentinel for days to catch memory leaks, cache invalidation bugs, and time-dependent failures that short test runs miss.
