What it does
Bayes is an agent skill from fainshare/Liam-Skills. Verify（验证·太虚三转·叩实）: decompose conclusion → testable predictions → external data validation. Use when user says "验证", "贝叶斯", "bayes", "靠谱吗", "深挖", "/bayes".
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 27 other files, including scripts and reference files (for example `DESIGN.md`, `agents/interface.yaml` and `agents/prompts/decide.md`).
It sits in Agent Workflows.
When your agent uses it
- Agent Workflows work in your project
Example prompts
- “/bayes”
- “/bayes”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- 拆预测（Phase 1）— 把笼统结论拆成具体的、可查证的方向性预测。每个核心断言必须同时拆出两个方向：证伪预测（falsification_prediction）和零假设预测（null_hypothesis_prediction）。
- 硬验证（B1）— 调 API 查数据 / 跑 shell 命令查代码，用代码判断预测是否成立。
- 软验证（B2）— 让 Claude 和 Qwen 各自独立解读原始资料/代码，看是否一致
- 找盲区（汇总）— 预测和实际不一致的地方 = 你的认知盲区
What it can do on your machine
Read from SKILL.md and the folder at commit 931ecc9. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/, which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Bayes loads about 1.1k tokens when it runs, and up to ~14k if it reads all its reference files. Until then it costs about 40 tokens; SKILL.md has 137 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 137 words (~1,058 tokens).

Questions about Bayes
What does Bayes do?
Verify（验证·太虚三转·叩实）: decompose conclusion → testable predictions → external data validation. Bayes is an agent skill from fainshare/Liam-Skills. Verify（验证·太虚三转·叩实）: decompose conclusion → testable predictions → external data validation.
When should I use Bayes?
Bayes fits situations like: agent Workflows work in your project.
How do I install Bayes in Claude Code?
Run `npx skills add fainshare/Liam-Skills --skill bayes -a claude-code`. Or copy the skill folder (skills/bayes in fainshare/Liam-Skills) into .claude/skills/bayes in your project. Claude Code loads it when a task matches its description.
How do I install Bayes in Codex?
Run `npx skills add fainshare/Liam-Skills --skill bayes -a codex`. Or copy the skill folder (skills/bayes in fainshare/Liam-Skills) into .agents/skills/bayes in your project. Codex loads it when a task matches its description.
Can I use Bayes in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add fainshare/Liam-Skills --skill bayes -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/bayes, .gemini/skills/bayes, .github/skills/bayes and .opencode/skills/bayes in your project.
What does Bayes need to run?
SKILL.md names no scripts, command-line tools or credentials: Bayes is instructions for the agent only.
Does Bayes access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Bayes safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Bayes use?
No licence was found for Bayes or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Bayes use?
About 1.1k tokens (SKILL.md is roughly 4.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 13k tokens, read only when the agent opens those files.
What are the alternatives to Bayes?
Skills that share tags, products or a category with Bayes: MCP Server Builder (anthropics/skills, 180k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 38k stars), Using Superpowers (farm-fe/farm, 5.6k stars) and Executing Plans Inline (obra/superpowers, 296k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Bayes?
fainshare (a GitHub user) maintains it in fainshare/Liam-Skills, which has 113 GitHub stars. The repository holds 8 skills in this directory. The repository was last updated on August 12, 2026.
