SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

SENTINEL prevents premature completion claims by requiring fresh verification evidence before stating that work is done.

Core Features & Use Cases

  • Gate-style verification: requires IDENTIFY, RUN, READ, VERIFY, and ONLY THEN to claim completion.
  • Applies to tests, builds, linting, and code changes to ensure verifiable results before merges or PRs.
  • Keeps teams honest by surfacing actual status with evidence rather than confident assumptions.

Quick Start

Run the verification workflow on your latest change to produce fresh evidence before claiming completion.

FAQPage Schema
How do I prevent premature completion claims during software development?

Prevent premature completion claims by enforcing fresh verification evidence before accepting any success claim. This requires running tests, builds, and linting to produce current outputs, ensuring statements about code changes are backed by verifiable results.

What is evidence-based verification for code changes and builds?

Evidence-based verification is a gate-style process that structures reporting by requiring IDENTIFY, RUN, READ, VERIFY, and ONLY THEN to claim completion. It ensures every code change or build success is backed by fresh verifiable results rather than assumptions.

How do I verify test and build outputs before claiming a task is complete?

Verify test and build outputs by running a structured workflow that identifies the target, executes the run, reads the output, and verifies the result. Only after this fresh evidence is confirmed can you claim completion for your code changes.

Does this verification workflow apply to linting and code changes?

Yes, this verification workflow applies directly to linting, tests, builds, and code changes. It requires current outputs for every claim, ensuring merges or PRs are backed by verifiable results instead of confident assumptions about quality assurance.

What's the best way to enforce quality assurance before merging a PR?

The best way to enforce quality assurance before merging is applying a gate-style verification process. By requiring fresh evidence from tests, builds, and linting through a structured IDENTIFY to VERIFY workflow, teams surface actual status and prevent premature completion claims.

Why do confident assumptions cause issues in software verification?

Confident assumptions cause issues in software verification because they allow premature completion claims without fresh evidence. Enforcing a structured workflow that requires current test, build, and linting outputs surfaces the actual status and keeps teams honest with verifiable results.
