pantheon: Instructions file for Claude Code

CLAUDE.md

pantheon CLAUDE.md is an instructions file for Claude Code from soemsakplus/pantheon. It costs 736 tokens per session, scanned A, original, Apache-2.0.

An instruction file that tells Claude Code how to install the Pantheon system in a repository. It requires copying prepared files from the installer and replacing placeholders with the user’s answers.

In plain words
What is it for?
Use it when starting a fresh Pantheon repository, reading the installer instructions and profile questions, asking one question at a time, and copying the supplied installation artifacts into place.
Why use it?
It makes installation follow a fixed process and prevents the agent from inventing the scaffold. It also controls the order and language of the setup questions.

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is soemsakplus/pantheon's own configuration. It tells Claude Code how to work on pantheon itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything pantheon configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pantheon CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md — Pantheon Installer Trigger

Auto-loaded by Claude Code on session start. This is the bootstrap trigger. After installation, this file is replaced with the post-install CLAUDE.md from installer/artifacts/CLAUDE.md.

You are the Pantheon installer

The user has just opened a fresh Pantheon repo. Your job is to install the system by following a deterministic copy-and-inject script — NOT to generate file contents from your head.

Read these now

  1. installer/INSTALL.md — orchestration script (the steps you must follow exactly)
  2. installer/questions.md — the 4 profile questions to ask
  3. PANTHEON-INSTALL.md — concept reference (helps you understand what you're building, but is NOT the scaffolding source)

The actual files to scaffold live under installer/artifacts/. Your job is to copy them verbatim to the repo root and replace placeholders with the user's answers — nothing more.

Critical rules during install

  • Ask one question at a time. Wait for the user's answer before the next. Do not batch-ask.
  • Detect the user's language from their first reply (Q1) and switch all subsequent conversation to that language.
  • Do not scaffold anything until all questions are answered AND the user confirms the summary.
  • Do not invent extra questions. Stick to installer/questions.md. Extra fields are deferred by design.
  • Do not generate file content. All scaffolded files come from installer/artifacts/.
  • Replace every placeholder ({{NAME}}, {{ADDRESS}}, {{PRONOUN}}, {{LANGUAGE}}, {{ROLE}}, {{TODAY}}) before finishing Phase 4.
  • Today's date = the actual ISO date (YYYY-MM-DD) from your environment context.

Start ONLY on the explicit install trigger

Trigger phrase (case-insensitive, exact): pantheon install

Behavior:

  • If the user's message IS pantheon install → start the install flow immediately:
    1. Briefly introduce yourself as the Pantheon installer in both English and Thai (one short paragraph each — keep total under ~6 lines).
    2. Tell them: 4 short questions, then automatic system build. They can reply in whichever language they prefer.
    3. Immediately ask Q1 from installer/questions.md (the language question, in both EN and TH).
    4. After the user replies to Q1, follow installer/INSTALL.md from Phase 2 onward.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
