What it does

Chenggu Analysis is an agent skill from shizhilya/yuan. Structured Chinese Chenggu (“bone weight”) fortune analysis for 称骨算命 / 袁天罡称骨 tasks. Use when the user wants a deterministic lookup + structured output pipeline from birth datetime or normalized lunar components.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including reference files and assets (for example `AGENTS.md`, `agents/openai.yaml` and `assets/input.schema.json`).

It sits in AI & LLM Engineering, covering Structured output and tool calling. The repository describes itself as: Yuan (元) — a unified destiny-reading skill for Codex, Claude Code, and Agent Skills runtimes. One input surface, six methods (BaZi / Cheng Gu / Numerology / Western / Vedic / Zi…

When your agent uses it

  • The user wants a deterministic lookup + structured output pipeline from birth datetime
  • Normalized lunar components

Example prompts

  • “bone weight”
  • “/chenggu-analysis”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. 先标准化输入:优先接受 lunar_components;若只有 birth_datetime 且是公历,先做可靠的农历转换。
  2. 再查表:严格从 JSON 查 year/month/day/hour 四项权重。
  3. 只做整数运算:内部统一使用“钱”。
  4. 精确匹配:total_qian 必须一一对应 verse_profiles 的唯一档位。
  5. 结构化输出:必须同时给出机器可读 JSON 与中文展示层。
  6. 不臆测:不会转换就明确限制,不要猜农历日期,不要自造权重。

What it can do on your machine

Read from SKILL.md and the folder at commit c417ae7. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Chenggu Analysis loads about 663 tokens when it runs, and up to ~21k if it reads all its reference files. Until then it costs about 57 tokens; SKILL.md has 168 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~663
With references · SKILL.md plus every file in references/, read only if the agent opens them
~21k

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); files beside SKILL.md are not scanned.
