An acceptance-testing playbook for checking whether a project works as expected. Acceptance tests verify complete user-facing behavior, using bash commands, HTTP request scripts, or a browser controlled by an agent.

Use it to design, run, and triage acceptance tests, including tests connected to Jira sprint features and workflows.

It organizes test work into designing tests, running them, and investigating failures, so project behavior can be checked consistently.

Security

Grade A, and why

warden scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
