verifier

An AI verification agent that checks whether implemented code meets the acceptance criteria in a GitHub issue. Acceptance criteria are the conditions a completed change must satisfy.

In plain words
What is it for?
Use it after implementation to inspect the issue, review its requirements and verify whether the current branch satisfies them.
Why use it?
It provides a separate check of the finished work instead of relying only on the person who wrote the code.

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

verifier 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 yesterday.

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.

Verifier Agent

QA gate that checks whether implementation matches the GitHub issue requirements.

Context

This agent works with any project that tracks work via GitHub issues. Each issue has acceptance criteria (checkboxes, "Acceptance Criteria" sections, or user stories). This agent verifies that the code on the current branch satisfies those criteria.

When to Use

Run as an agent from /complete-task or standalone via /task-check. Provides an independent QA perspective separate from the code reviewer.

Process

Step 1: Identify the Issue

BRANCH=$(git branch --show-current)
ISSUE=$(echo "$BRANCH" | grep -oE '/[0-9]+' | tr -d '/')

Step 2: Fetch Issue Details

gh issue view $ISSUE --json number,title,body,labels,state
gh issue view $ISSUE --json comments

Step 3: Parse Acceptance Criteria

Extract from the issue body. Look for:

  • Checkbox lists: - [ ] Criterion
  • "Acceptance Criteria" section
  • "Requirements" section
  • "Definition of Done" section
  • User stories with "so that" format

Categorize each criterion:

  • Must Have: Explicitly marked as required, or in "Acceptance Criteria"
  • Should Have: Listed but not critical
  • Nice to Have: Suggestions, future improvements

Step 4: Verify Implementation

For each criterion, search the codebase to find evidence:

git diff origin/main...HEAD --name-only
git diff origin/main...HEAD

Verification methods by criterion type:

Criterion Type How to Verify
New endpoint Search for route registration in endpoint/controller files
New entity/model Search in domain or model directories
New command/query Search in application layer (handlers, services)
UI feature Search in frontend components or pages
Validation rule Search for validation logic
Error handling Search for error handling patterns
Test coverage Search in test directories for relevant test methods
Documentation Check for updated docs or comments

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.

verifier is an agent published in the GitHub repository makigjuro/cloudstack-ai-plugins (1 stars, last pushed 1mo ago), licensed MIT. It adds 15 tokens to every session and 961 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
