A post-merge user-acceptance check for a bug fix that follows reproduction steps and compares the result before and after the change. UAT means testing the change in an environment that represents real user use.

Use it to verify merged bug fixes in UAT, gather comparative evidence, and update the related ticket status.

It confirms that the reported problem is actually fixed and that the fix did not merely look correct in development. It records evidence before updating the ticket.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.01222
Opus 5	$0.00000	$0.00611
Sonnet 5	$0.00000	$0.00244
Haiku 4.5	$0.00000	$0.00122

Security

Grade A, and why

verify-bug 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 8d 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.

Verify Bug

Post-merge UAT verification workflow. Walks JIRA reproduce steps, performs comparative audits (Before/After), attaches evidence to JIRA, and transitions status on PASS.

Input: $ARGUMENTS

Instructions

Execute the following steps for $ARGUMENTS.

Verify-Bug — UAT Audit

Goal: Prove a bug fix works in the UAT environment via comparative Before/After evidence, then transition ticket status.

Input

/verify-bug <jira-url-or-key> [--baseline-image <url>]

Workflow

Step 0: Pre-flight & Data Gathering

[!TIP] Sub-Agent Delegation: If your platform supports sub-agents (e.g., Claude, OpenCode, Gemini, Kiro), delegate steps 1-3 below to your JIRA Analyst sub-agent (e.g., @specialist-jira-analyst). If sub-agents are NOT supported (e.g., Antigravity, Windsurf), you must execute these steps yourself.

Parse JIRA: Extract Market, Reproduce steps, and Expected Result.
Resolve Markets: If multiple markets, prompt for scope (Full/Sample/Custom).
Fetch Test Data: Call Confluence for Test data - <MARKET> UAT. Parse credentials and module-specific data (e.g., customer codes).
Credential Check: Rule out expired accounts before starting sessions.
Fallback: If Jira/Confluence MCPs are unavailable, request exported ticket/test-data text and continue with local evidence.

Step 1: Comparative Audit (Execution Phase)

For each market in scope:

Environment Setup: Run the DNS probe from <SKILLS>/common/common-web-visual-testing/references/diagnostic-decoder.md; if it indicates VPN is required, connect VPN and retry.
Named Session: Start playwright-cli -s={TICKET}-{MARKET} or Appium session.
Walk Steps: Execute reproduction steps.
- Hover Discipline: Always hover the target element (warning, button, price) before screenshotting.
- Stability: Disable animations and mask dynamic fields (clocks, balances).
Verdict Determination:
- PASS: End-state matches Expected Result.
- FAIL: End-state matches Actual Result or original bug screenshot.
- NEEDS-HUMAN: Deviates from both.

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.
