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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00094 | $0.01373 |
| Opus 5 | $0.00047 | $0.00687 |
| Sonnet 5 | $0.00019 | $0.00275 |
| Haiku 4.5 | $0.00009 | $0.00137 |
Grade A, and why
ring:applying-licenses 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 8d 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 — 166 lines — stays where its author put it; the contents beside it link to each section on GitHub.
License Management
When to use
- User requests to set, apply, or switch a license on a repository
- Scaffolding a new service from the boilerplate
- Task mentions "license", "licensing", "license header", "Apache 2.0", "ELv2", "proprietary"
- Gate 0 of dev-cycle when no LICENSE file exists
Skip when
- Repository already has requested license AND all headers match AND SPDX is correct (verified)
- Non-code repositories (documentation-only, design assets)
Related
Complementary: ring:running-dev-cycle, ring:implementing-tasks
You orchestrate. Agents update source headers. NEVER apply a license without user confirmation.

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ring:applying-licenses is a skill published in the GitHub repository LerianStudio/ring (211 stars, last pushed 19d ago), licensed Apache-2.0. It adds 94 tokens to every session and 1,373 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
