metago-deep-reasoning

metago-deep-reasoning is a skill for Claude Code, Codex from metago-ai/metagolifeform. It costs 32 tokens per session (1,154 once invoked), scanned A, original, MIT.

A Chinese-language framework for analysing difficult problems through four stages: defining the issue, developing several lines of reasoning, checking them and choosing a conclusion.

In plain words
What is it for?
Complex decisions, technical evaluations, root-cause analysis, strategy exercises and academic questions that need multiple possible explanations and cross-checking.
Why use it?
It gives an agent a structured way to examine competing explanations, assumptions, evidence, risks and alternatives.

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

metago-deep-reasoning 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 12d 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.

What it actually says

FIPO深度推理

触发条件

当用户明确提到"深度推理"、"FIPO"、"多维度分析"、"深度思考"、"推理链"、"复杂决策分析"等关键词,或面对需要进行多路径推理、交叉验证假设、生成最优解与备选方案的复杂问题域时,自动触发本技能。适用于仅靠直觉或单线逻辑无法给出可靠结论的情境。

适用场景

  • 复杂决策分析:在多方利益、多重约束条件下进行决策权衡
  • 技术方案评估:对多个候选方案进行多维度对比与验证
  • 根因分析:对生产故障、性能瓶颈、组织问题等进行深层归因
  • 战略推演:对未来不确定场景进行多路径预判
  • 学术研究:对开放性命题进行严谨论证

执行步骤

1. F阶段(Focusing)——聚焦核心问题

  • 识别问题本质,剥离表象干扰
  • 明确问题边界:时间维度、空间维度、参与主体
  • 列出约束条件:硬约束(必须满足)与软约束(可妥协)
  • 输出《问题定义书》:含问题陈述、边界、约束清单

2. I阶段(Inferring)——多路径推理

  • 基于问题定义生成3-5条独立推理链
  • 每条推理链标注前提假设、推理路径、中间结论
  • 推理链之间需保持独立性,避免同源偏差
  • 记录推理路径的分歧点和汇合点

3. P阶段(Proving)——验证推理链

  • 对每条推理链的关键假设进行交叉验证
  • 寻找反例和证伪证据,避免确认偏误
  • 标注假设的可信度(高/中/低)及验证来源
  • 剔除无法验证或被证伪的推理链

4. O阶段(Optimizing)——优化推理结论

  • 综合存活的推理链,提炼最优结论
  • 生成备选方案集(至少2个),标注差异点
  • 对每个方案进行风险评估与可控性分析
  • 给出推荐结论与决策路径

5. 推理深度评估

对F、I、P、O四个阶段分别评分(1-5分):

  • 1分:浅层,仅触及表象
  • 3分:中层,完成基本分析
  • 5分:深层,触及本质并完成交叉验证
  • 计算综合推理深度 D = Σ(阶段得分) / 4

6. 输出推理报告

输出包含:问题定义书、推理链全图、验证证据表、最优解+备选方案、推理深度评分、置信度评估(0-100%)、关键风险点。

输出格式

■ 问题定义:[边界|约束]

  链1:[前提]→[路径]→[结论](验证状态:✓/✗)

■ 推理深度:F=4 I=3 P=4 O=5 综合=4.0
■ 置信度:85%
■ 关键风险:...

核心理论

本技能基于元构生命体理论体系中的 FIPO深度推理算法,来源于《卷2第六章》。FIPO为四阶段递进式深度推理框架,强调从聚焦(F)到推理(I)到验证(P)再到优化(O)的闭环过程,区别于线性单链推理,要求多路径并行与交叉验证。

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.

metago-deep-reasoning is a skill published in the GitHub repository metago-ai/metagolifeform (4 stars, last pushed 11d ago), licensed MIT. It adds 32 tokens to every session and 1,154 once invoked, about $0.0002 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.
