uat-signoff

uat-signoff is a command for GitHub Copilot from HoangNguyen0403/agent-skills-standard. It costs 23 tokens per session (567 once invoked), scanned A, original, MIT.

A user-acceptance testing, or UAT, workflow that guides a business approver through a plain-language demonstration of a verified feature. It records whether each expected outcome is accepted, rejected, or accepted with conditions.

In plain words
What is it for?
Use it after verification passes and before release to prepare a demo, ask the approver for decisions, record conditions, and route rejected work back for fixing.
Why use it?
It turns technical verification into an explicit business decision and prevents release without recorded approval of the feature's expected outcomes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

uat-signoff 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 6d 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.

UAT Signoff Workflow

Goal: Convert a verify-work PASS into an explicit, evidence-linked business acceptance decision before release.

Steps

  1. Load scope:
    • verify-work report, AC list, PRD/BRD-lite business objective, and inherited operator_profile (carry, do not re-infer).
    • Load common-operator-profile.
  2. Draft demo script:
    • Map each AC to an observable business outcome in plain language; omit file paths, commands, and code identifiers from the primary script.
    • For operator_profile=business or hybrid, this plain-language script is the primary artifact; keep technical trace in a trailing appendix.
  3. Walk the signoff:
    • Present each AC outcome and ask the approver to accept or reject.
    • Ask max 3 blocking questions at a time with a recommended default and 2-3 options.
    • Record conditions attached to any conditional acceptance.
  4. Capture decision:
    • Signoff owner, date, and per-AC accept/reject status.
    • Reject on any AC -> route to dev-fix.
    • Full accept -> route to deploy-release.

Runtime Contract

  • Use after verify-work PASS on a feature, before deploy-release.
  • Required inputs: a PASS verification report with an AC list to demo against.
  • Return BLOCKED only when no verification report exists or the approver is unavailable in autonomous/channel mode.

Handoff Payload

  • slug, operator_profile, signoff owner, per-AC decision, conditions, outcome report, next workflow.

Blocking Questions

  • Ask max 3 at a time with a recommended default and 2-3 options.

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.
