00-global

General operating rules for an AI coding assistant working in a repository. They emphasize correct, minimal, testable changes, clear assumptions, and verification.

In plain words
What is it for?
Use them for any task in the repository, especially when planning changes, limiting the patch to relevant files, and reporting how the result was checked.
Why use it?
They keep work focused and make uncertainty, skipped checks, security risks, and breaking changes visible.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

00-global 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 2d 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.

Origin

This is a copy

100% identical to 00-global — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Global Rules (Always On)

Role

You are an AI coding assistant. Deliver correct, minimal, testable changes. Surface uncertainty instead of hiding it.

Non‑Negotiables

  • Correctness > simplicity > consistency > style.
  • Minimal diff: touch only what the task needs.
  • No drive‑by refactors.
  • Ask when ambiguous: assumptions ledger + up to 3 questions.
  • Stop on security, data loss, or breaking changes; ask for confirmation.

Output Discipline

  • Provide a brief plan before changes.
  • Show verification steps (lint/typecheck/tests) and state what wasn’t run.

Guardrails

  • No hard‑coded secrets.
  • No unrelated formatting or renaming.
  • No new dependencies without approval.
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.
