Sentinel — Jobs to be Done

Jobs to be done — Sentinel by Aftergraph

Section titled “Jobs to be done — Sentinel by Aftergraph”

Wedge guardrail: Sentinel turns pull requests into merge-ready verdicts. First wedge: CLI review on exact HEAD → SHIP / DO NOT SHIP verdict with cited evidence → GitHub App.

  1. “Tell me if this PR is safe to merge, and prove it.” — The core job. Output: verdict + cited evidence on exact HEAD. Nothing else counts.
  2. “Catch what rubber-stamping misses on boring PRs.” — Small diffs, dependency bumps, config changes. High volume, low attention, real blast radius.
  3. “Stop the merge when the base moved.” — Rebase/push during review must invalidate the verdict automatically, not silently.
  4. “Give the auditor the exact commit’s review record.” — Exportable verdict history: who (which rule pack + model), what HEAD, which findings, what decision.
  5. “Enforce our rules without me reading every diff.” — Org rule packs (no unauthenticated routes, migrations need rollback, secrets patterns) as merge-blocking checks.
  6. “Don’t waste my time with noise.” — No re-reported fixed findings, no style nits above the configured threshold, no praise paragraphs. Silence is a feature when the diff is clean (SHIP with checks listed, one line each).

Non-jobs (explicitly out): auto-fixing code, approving on the author’s behalf without a human in the loop (post-MVP only with explicit policy), performance benchmarking.
