  • Evaluating stocks through Qiu Guolus value-quality lens: stay within circle of competence
  • Focus on industry leaders with structural advantages
  • Demand simple clear thesis before investing

Example prompts

  • “/qiuguolu-value-quality”

Workflow steps

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

  1. Identify the industry leader with structural advantage.
  2. Write the thesis in 2-3 sentences. If you can't, pass.
  3. Check valuation relative to quality and growth.
  4. Own only if the thesis is simple and the leader is clear.

What it can do on your machine

Read from SKILL.md and the folder at commit 2844d78. 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 (its code samples are markdown).

    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

Qiuguolu Value Quality loads about 461 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 194 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
~461

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.

Qiu Guolu Value Quality

Use this skill to apply Qiu Guolu / 邱国鹭-style judgment.

When To Use

Use this skill when the user asks for:

  • Qiu Guolu-style value analysis
  • whether a company is an industry leader worth owning
  • simple clear thesis evaluation
  • A-share quality stock screening

Trigger phrases include 邱国鹭, Qiu Guolu, 投资中最简单的事, 行业龙头, value quality A股, 简单清晰.

Do Not Use When

  • Another skill fits better.
  • Critical data for this model is missing.
  • The user wants guaranteed returns or unbounded leverage.
  • The request is generic chatter with no decision.

Inputs Needed

  • Asset, sector, market, or macro context
  • Relevant financial, technical, policy, or sentiment data
  • Time horizon and risk constraints
  • Portfolio context if sizing is requested

Process

  1. Identify the industry leader with structural advantage.
  2. Write the thesis in 2-3 sentences. If you can't, pass.
  3. Check valuation relative to quality and growth.
  4. Own only if the thesis is simple and the leader is clear.
