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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00024 | $0.00666 |
| Opus 5.5 | $0.00010 | $0.00266 |
| Sonnet 5.5 | $0.00005 | $0.00133 |
| Haiku 4.5 | $0.00002 | $0.00067 |
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 1mo 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copyright Header Rules
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__.pyfiles (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:
Copyright (c) <year> <Company> - All Rights Reserved.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.

copyright-headers is a skill published in the GitHub repository gosha70/code-copilot-team (7 stars, last pushed 17d ago), licensed MIT. It adds 24 tokens to every session and 666 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
