ultra-verify

ultra-verify is a skill for Claude Code, Codex from rocky2431/ultra-builder-pro. It costs 65 tokens per session (1,570 once invoked), scanned A, original, MIT.

A workflow for asking Claude, Gemini, and Codex to independently review a question, bug, audit, or estimate, then combining their results.

In plain words
What is it for?
It helps with architecture decisions, diagnosing bugs, code audits, and estimating development work.
Why use it?
It reduces reliance on one analysis by comparing separate conclusions and reporting where the models agree.

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

ultra-verify 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/verify_wait.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Ultra Verify - Three-Way AI Verification

Orchestrate Claude + Gemini + Codex for independent three-way analysis. Each AI works independently, then Claude synthesizes with a confidence score based on consensus.

Prerequisites

  • Gemini CLI installed: npm install -g @google/gemini-cli + authenticated
  • Codex CLI installed: npm install -g @openai/codex + codex login
  • Verify both: gemini --version && codex --version

Usage

/ultra-verify decision <question>    # Architecture/design decision — three independent analyses
/ultra-verify diagnose <symptoms>    # Bug diagnosis — three sets of hypotheses
/ultra-verify audit <scope>          # Code audit — findings ranked by consensus
/ultra-verify estimate <task>        # Effort estimation — confidence from agreement

Workflow Tracking (MANDATORY)

On command start, create tasks for each major step using TaskCreate:

Step Subject activeForm
1 Session Setup + Claude Analysis Writing Claude analysis...
2 Launch External AIs Launching Gemini + Codex...
3 Wait for Completion Waiting for AI outputs...
4 Collect + Synthesize Synthesizing results...

Before each step: TaskUpdatestatus: "in_progress" After each step: TaskUpdatestatus: "completed" On context recovery: TaskList → resume from last incomplete step

Orchestration — STRICT SEQUENTIAL EXECUTION

RULE: Each step REQUIRES the output of the previous step. Never skip ahead. Never start synthesis without wait script JSON.

Step 1: Session Setup + Claude Analysis

SESSION_ID="$(date +%Y%m%d-%H%M%S)-verify-<mode>"
SESSION_PATH=".ultra/collab/${SESSION_ID}"
mkdir -p "${SESSION_PATH}"

Write Claude's own analysis to ${SESSION_PATH}/claude-analysis.md FIRST (before reading external AI output).

Step 2: Launch External AIs (both run_in_background: true, timeout: 600000)

Launch BOTH commands in a single message with two parallel Bash calls. Both MUST use run_in_background: true.

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.
