repo-is-not-a-runtime

repo-is-not-a-runtime is a skill for Claude Code from Aitherium/awdk. It costs 54 tokens per session (1,467 once invoked), scanned A, original, no licence file.

An architecture rule for repositories used by coding agents: the source-code repository should not be treated as the place where runtime data and working state live. It focuses on separating those concerns so repository contents do not grow unnoticed.

In plain words
What is it for?
It helps design and maintain agent-driven repositories so temporary or runtime data is kept out of the source tree.
Why use it?
Mixing runtime files with source code can consume disk space and hide operational problems until they cause failures. Keeping the roles separate makes the repository easier to manage.

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

repo-is-not-a-runtime 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
