What counts as evidence in ai-agents and how to produce it. Covers the TESTING-RIGOR pos+neg+edge bar, test layout and collection reality, coverage proof commands, runtime-contract tests with negative controls, and ADR-034 QA skip semantics at session end. Use when you say `what counts as evidence`, `how do I test this change`, `run skill tests`, `can I skip QA`. Do NOT use for CI failure triage (use `ai-agents-debugging-playbook`) or measurement tooling (use `ai-agents-diagnostics-toolkit`).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# ai-agents Validation and QA

<!-- vendor-portability: contributor-facing knowledge pack for the rjmurillo/ai-agents repo itself; intentionally references upstream paths (.agents/, .claude/, scripts/, build/) because its audience is repo contributors, not plugin consumers (issue #2050) -->
This repo runs verification-based governance: a claim is true when a gate, test, or command output says it is, not when an agent asserts it. This skill defines the evidence bar for code changes, where tests live and how they are collected, the anti-pattern canon (each entry paid for by a real incident), and the QA gate semantics at session end.

Audience: a zero-context contributor (human or model) about to write, run, or skip tests in this repository.

## Triggers

- `what counts as evidence`
- `how do I test this change`
- `run skill tests`
- `can I skip QA`

## Scope Boundaries

| You want | Use instead |
|----------|-------------|
| Triage a red CI check or a blocked push | `ai-agents-debugging-playbook` |
| Measure drift, budgets, telemetry, coverage trends | `ai-agents-diagnostics-toolkit` |
| Probe an external tool's runtime behavior empirically | `ai-agents-empirical-probe-toolkit` |

How to install

The exact contents, by fingerprint

mdr add rjmurillo/ai-agents/ai-agents-validation-and-qa@sha256:73c9ec07931fddce

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
