run-regression

run-regression is a skill for Claude Code from insideout-ai/make-it-work. It costs 75 tokens per session (11,060 once invoked), scanned B, original, no licence file.

A tool that runs a project's regression tests, either across the whole project or for selected areas, and reports which checks passed or failed. Regression tests check that existing behavior still works after changes.

In plain words
What is it for?
It helps verify a project after changes by running all tests or tests for particular domains or use cases.
Why use it?
It reduces the need to run test commands manually and makes the outcome of a full or focused test run visible.

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 B, and why

run-regression scanned grade B with 1 finding 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.

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.

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.
