copyright-headers

Rules for adding copyright and licensing text to new source files when the project defines those details in its root CLAUDE.md file. They specify which file types receive headers and which files are excluded.

In plain words
What is it for?
Use it when generating new code files to determine the company, license, year, header format, and file types that should or should not receive headers.
Why use it?
It keeps newly created source files aligned with the project's stated ownership and licensing requirements without changing existing files unnecessarily.

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

copyright-headers 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 yesterday.

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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When a project's CLAUDE.md contains a ## Copyright & Licensing section, add a copyright header to every new source file you create.

Trigger

Check for a ## Copyright & Licensing section in the project CLAUDE.md (the one in the project root — not the global ~/.claude/CLAUDE.md).

If present, extract:

  • Company from the - **Company**: … line
  • License from the - **License**: … line

Which files get headers

Apply to new files with these extensions: .py, .sh, .bash, .java, .kt, .js, .ts, .tsx, .jsx, .go, .rs, .c, .cpp, .h, .css, .scss, .html, .xml, .yaml, .yml, .toml

Do not add headers to:

  • Auto-generated files (contain @generated, Code generated, or similar markers)
  • __init__.py files (conventionally empty or trivial)
  • Lock files (package-lock.json, poetry.lock, yarn.lock, etc.)
  • JSON / JSONC (no comment syntax)
  • Files you did not create — never modify existing files just to add a header

Header format

Compose the header as two lines:

  1. Copyright (c) <year> <Company> - All Rights Reserved.
  2. This software may be used and distributed according to the terms of the <License> license.

Use the current calendar year.

By file type

Python / Shell / YAML / TOML / Ruby — hash comments:

# Copyright (c) <year> <Company> - All Rights Reserved.
# This software may be used and distributed according to the terms of the <License> license.

Java / Kotlin / JavaScript / TypeScript / Go / Rust / C / C++ — line comments:

// Copyright (c) <year> <Company> - All Rights Reserved.
// This software may be used and distributed according to the terms of the <License> license.

HTML / XML — block comment:

<!-- Copyright (c) <year> <Company> - All Rights Reserved. -->
<!-- This software may be used and distributed according to the terms of the <License> license. -->

CSS / SCSS — block comment:

/* Copyright (c) <year> <Company> - All Rights Reserved. */
/* This software may be used and distributed according to the terms of the <License> license. */

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.
