compare-geo-retest

compare-geo-retest is a skill for Codex from stella-dust/autoxeo-agent-codex-plugin. It costs 60 tokens per session (450 once invoked), scanned A, original, Apache-2.0.

A skill for checking whether two GEO measurements can be fairly compared and for calculating and explaining their differences. GEO, or generative-engine optimisation, concerns how brands appear in AI-generated answers.

In plain words
What is it for?
Use it to compare a baseline with a later retest, assess mention, recommendation, ranking, source, and coverage changes, and create the next review plan.
Why use it?
It prevents changes from being called an improvement when the questions, platforms, language, model version, method, or collection period changed. It also keeps real changes separate from sample failures and other limitations.

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

compare-geo-retest 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/compare-retest.mjs), 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.

What it actually says

GEO 同题复测分析

复测先证明可比,再讨论变化。当前 Codex 会话解释变化;脚本只核对问题身份和计算差异。

工作流

  1. 读取基线与复测 dataset/summary。两批必须记录 question set、问题 identity hash、平台、区域/语言、模型/能力版本、采集窗口、方法版本和 Evidence 状态。
  2. 运行 scripts/compare-retest.mjs <baseline-summary.json> <retest-summary.json> <comparison.json>。若问题集或方法版本不一致,结果必须为 not_comparable,不得输出效果结论。
  3. 分开解释:品牌正文提及变化、推荐变化、首位变化、来源命中变化、问题覆盖变化和平台结构变化。样本失败、平台版本变更和时间窗口差异是限制,不是品牌效果。
  4. 变化按三类输出:可确认事实、合理解释、待验证假设。任何归因都必须指出还能由什么外部变化解释。
  5. 生成 分析/复测/<date>-复测分析.md对比结果.json下一周期.json。列出保留动作、停止动作、修订内容、未解决问题和下一复测窗口。
  6. 报告必须明确基线/复测样本数、排除项、可比性判定、Evidence refs 和局限;完成后登记本地产物 hash。

真实性边界

  • “同题”意味着稳定问题 identity,不是文本看起来相似。
  • 小样本变化不自动代表趋势;不得伪造显著性或 ROI。
  • 案例中的正向结果只用于学习报告结构,不能作为当前项目先验。
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
