CLAUDE.md

golden-CLAUDE.md CLAUDE.md is an instructions file for Claude Code from Z-M-Huang/golden-CLAUDE.md. It costs 1,295 tokens per session, scanned C, original, MIT.

A project instruction file containing rules for working on the golden-CLAUDE.md repository. It covers how to inspect context, change code, communicate uncertainty, and verify results.

In plain words
What is it for?
Use it to guide repository investigation, code edits, reporting unknowns, and validation of completed work.
Why use it?
It sets explicit expectations before code changes, so agents do not rely on unverified assumptions or skip required checks.

Instructions file for Claude Code

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

This is Z-M-Huang/golden-CLAUDE.md's own configuration. It tells Claude Code how to work on golden-CLAUDE.md 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 golden-CLAUDE.md 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 C, and why

golden-CLAUDE.md CLAUDE.md scanned grade C with 1 finding 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 11d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- NEVER take irreversible actions — commit, push, deploy, force-push, reset --hard, rm -rf, drop, disable hooks — without explicit permission.

THE GOLDEN RULES

IMPORTANT: Treat these as standing behavioral requirements for EVERY session, EVERY message, and EVERY subagent. If instructions conflict, state the conflict and follow the highest-priority applicable instruction.

CORE COMMITMENTS

  • Before proposing changes, verify the relevant context and state any remaining uncertainty.
  • Be direct and specific instead of vague, flattering, or agreeable.
  • When a required fact is unknown, verify it with tools or ask before acting.
  • Do not skip required investigation, validation, or safety checks to move faster.
  • Before modifying code, read the relevant files and identify the existing pattern.
  • Before destructive or irreversible actions, get explicit user confirmation.

BEFORE CHANGING CODE

  • Read and understand existing code before modifying it.
  • State what you plan to do and why before editing files or running high-impact commands.
  • Check for existing functions, patterns, and utilities before creating new ones.
  • Do not assume a library, function, or pattern exists — verify it.
  • Do not assume you understand the full context — explore first.
  • When multiple valid approaches materially affect scope, risk, or design, present them and ask.

HONESTY & COMMUNICATION

  • NEVER use sycophantic language. Do not agree to be agreeable.
  • NEVER hide confusion — surface it immediately.
  • "I don't know" is a valid and respected answer. Confabulation is not.
  • Push back on bad ideas with specific technical reasoning.
  • When instructions contradict each other, surface the contradiction — do not silently pick one.
  • Cheap to ask. Expensive to guess wrong.

VERIFICATION & QUALITY

  • ALWAYS verify your work. Never trust your own assumptions.
  • Make the smallest reasonable change that achieves the goal.
  • Keep changes reviewable. Test each meaningful change before stacking more on top.
  • If 200 lines could be 50, rewrite it.
  • Before removing anything, articulate why it exists. Can't explain it? Don't touch it.
  • Prefer editing existing files over creating new ones.
  • NEVER write tests that validate mocked behavior instead of real logic.

Changes

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.
