What it does

Geju is an agent skill from hylarucoder/hai-stack. Challenges an overly conservative, incremental, or compatibility-led proposal with a bold target model, a concrete kill/merge/split list, materially different options, and a falsifiable first proof point. Use when the user asks to think bigger, open the design space, or imagine the clean target without legacy constraints(打开格局、别太保守、不要被兼容绑架). Use goudi to pressure-test how the chosen direction lands, and hai-idea to decide whether the idea deserves doing at all.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `SKILL.zh_CN.md`, `agents/openai.yaml` and `references/frame-opening-moves.md`).

When your agent uses it

  • The user asks to think bigger
  • Open the design space
  • Imagine the clean target without legacy constraints(打开格局、别太保守、不要被兼容绑架)

Example prompts

  • “Use the geju skill to challenge an overly conservative, incremental, or compatibility-led proposal with a bold target model, a concrete…”
  • “/geju”

Workflow steps

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

  1. Reframe at the highest useful level. What is the real decision? What is the system trying to become? What would be obvious if we were not…
  2. Name the inherited constraint. Compatibility, migration difficulty, existing naming, local implementation shape, organizational habit…
  3. Decide whether the constraint is real. This is the operational heart of the skill — apply it in exactly this spot.
  4. Offer the high-格局 thesis. Say the clean direction plainly. Explain what to delete, preserve, merge, split, or rebuild. Include the…
  5. Apply at least one move from Ways To Open The Frame.
  6. Give 2-3 options only if they materially differ, using the canonical labels: Conservative path / Clean target / Staged clean path…
  7. Bring it back to execution. Identify the first irreversible decision, the first proof point, what would falsify the thesis, and what not…

What it can do on your machine

Read from SKILL.md and the folder at commit a6c7ed2. 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

Geju loads about 1.8k tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 117 tokens; SKILL.md has 985 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~117
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.9k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 985 words (~1,823 tokens).

“For Chinese readers, see SKILL.zh_CN.md. The English SKILL.md is the execution source of truth.”

When should I use Geju?

Geju fits situations like: the user asks to think bigger; open the design space; imagine the clean target without legacy constraints(打开格局、别太保守、不要被兼容绑架).

How do I install Geju in Claude Code?

Run `npx skills add hylarucoder/hai-stack --skill geju -a claude-code`. Or copy the skill folder (skills/geju in hylarucoder/hai-stack) into .claude/skills/geju in your project. Claude Code loads it when a task matches its description.

How do I install Geju in Codex?

Run `npx skills add hylarucoder/hai-stack --skill geju -a codex`. Or copy the skill folder (skills/geju in hylarucoder/hai-stack) into .agents/skills/geju in your project. Codex loads it when a task matches its description.

Can I use Geju 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 hylarucoder/hai-stack --skill geju -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/geju, .gemini/skills/geju, .github/skills/geju and .opencode/skills/geju in your project.

What does Geju need to run?

SKILL.md names no scripts, command-line tools or credentials: Geju is instructions for the agent only.

Does Geju 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 Geju 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. Review the folder before installing.

What licence does Geju use?

Geju has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Geju use?

About 1.8k tokens (SKILL.md is roughly 7.3k 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 1.1k tokens, read only when the agent opens those files.

What are the alternatives to Geju?

Skills that share tags, products or a category with Geju: Geo Proposal (sickn33/agentic-awesome-skills, 47k stars), Better Proposals Automation (ComposioHQ/awesome-claude-skills, 77k stars), Agent Challenges (ruvnet/ruflo, 74k stars) and Contract And Proposal Writer (alirezarezvani/claude-skills, 28k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
