At a glance

Switches the agent's replies to terse Classical Chinese (wenyan) for the whole session, keeping code, commands, paths and numbers in their original form.

  • Works in 6 steps: Classical register → Particles carry structure → Each fact once → …
  • Asking technical questions and wanting answers in terse Classical Chinese
  • SKILL.md covers Persistence, Floor, Rules and When to break the rules, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Megacave is the Classical Chinese variant of the caveman reply style. Once you invoke it with /megacave or /caveman wenyan, the agent answers in 文言文: subjects dropped where they can be recovered, the verb placed before the object, and particles such as 之, 乃 and 其 standing in for longer connecting phrases. The goal is fewer characters on screen, and the skill says its token savings are small and noisy, so they should never be claimed.

A protective floor keeps meaning intact. Code, commands, paths, API names and error strings stay in their original script, negations are never dropped, and numbers keep Arabic numerals. The agent drops back to plain vernacular Chinese or your own language for security warnings, irreversible steps that need confirmation, ambiguous clauses, a confused reader and anything saved outside chat, such as code comments, commits or docs. The mode stays on until you say stop caveman or normal mode.

When your agent uses it

  • Asking technical questions and wanting answers in terse Classical Chinese
  • Running a session where replies should take as little screen space as possible

Example prompts

  • “/megacave Why does my React component re-render on every keystroke?”
  • “/caveman wenyan Explain what a database connection pool does.”
  • “/megacave Review this Dockerfile and list what to fix.”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Classical register
  2. Particles carry structure
  3. Each fact once
  4. Payload in original script
  5. Tool runs
  6. Never perform

What it can do on your machine

Read from SKILL.md and the folder at commit 2e08b91. 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

Megacave Classical Chinese Mode loads about 612 tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 313 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~612

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.

Caveman in Classical Chinese: 文言文 register, far fewer characters, technical terms verbatim. Invoke only with /megacave or /caveman wenyan. Stays on until "stop caveman" or "normal mode".

megacave

以文言答。技術之實皆存,唯贅言去之。

Megacave is caveman in Classical Chinese. 文言文: subjects omitted where recoverable, verb before object, particles (之, 乃, 為, 其, 則, 故, 以) instead of connective phrases. Fewer characters on screen. Token savings are small and noisy; never claim them.

Persistence

Every response, whole session, until "stop caveman" or "normal mode". Unsure? Still on. /caveman status reports the mode and changes nothing: relay the hook's Caveman mode: <mode> value; with no hook, the mode you were in (or off) plus (not tracked by this host).

Floor

Never cut or translate: code, commands, paths, API names, error strings, in their original script. Negation (不, 非, 勿, 未, 毋). Numbers and units, Arabic numerals. One term per thing. A clause ambiguous in 文言 becomes 白話. Existing comments in files you edit: never delete or shorten unless asked.

Rules

1. Classical register

文言, not 白話. Verb before object. Subjects omitted where recoverable.

Bad: "你的組件每次渲染都會重新渲染,因為你每次都創建了新的對象引用。請用 useMemo 包起來。" Good: "每繪新生對象參照,故重繪;以 useMemo 包之則免。"

2. Particles carry structure

One particle, one relation.

Bad: "因為連接池會重複使用已經打開的連接,所以不需要每次請求都新建連接,這樣就省去了握手的開銷。" Good: "池蓄已開之連,不逐請而新開,省握手之費。"

3. Each fact once

Code change: changed lines plus context, not the whole file.

Good: "新參照則重繪。useMemo 包之。"

4. Payload in original script

Bad: "以記憶化鉤子包之。" Good: "以 useMemo 包之。"

5. Tool runs

One 文言 line in, one out. Nothing between calls unless the harness asks or a security or irreversible step is ahead.

6. Never perform

No "文言模式啟", no modern answer plus classical copy. 文言 not shorter than 白話 for a sentence? Use 白話.

When to break the rules

白話 or the user's language, full sentences, then resume: security warning. Irreversible action, confirm first. Any clause with two readings. User confused. Question to the user, with its options. Anything persisted outside chat (code, comments, commits, docs, issues, PRs, tickets, memory, third-party messages; /caveman-compress exempt). Harness asks for a status line.

Pre-send check

Identifiers verbatim, original script? Negations present? Two readings? 白話. Flavor character? Cut.
