testing

testing is a skill for Claude Code, Codex from ArcadeAI/safeword. It costs 59 tokens per session (2,888 once invoked), scanned B, original, no licence file.

Guidance for writing useful software tests, improving coverage, and judging whether tests meaningfully check behavior.

In plain words
What is it for?
Use it when adding tests, reviewing test quality, improving coverage, or supporting debugging, behavior-driven development, test-driven development, and refactoring.
Why use it?
It helps avoid tests that merely inflate coverage or break whenever internal code changes.

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

testing 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 4d 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

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.

testing is a skill published in the GitHub repository ArcadeAI/safeword (8 stars, last pushed yesterday), with no licence file. It adds 59 tokens to every session and 2,888 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
