ci-flaky-timing-luck

ci-flaky-timing-luck is a skill for Claude Code from maxrave-dev/kotlin-footguns. It costs 91 tokens per session (1,459 once invoked), scanned A, original, GPL-3.0.

A troubleshooting workflow for finding CI steps that pass or fail because of timing, rather than because the code is correct. CI, or continuous integration, automatically builds and tests code on a runner.

In plain words
What is it for?
Investigating runner-image-related CI failures, same-name mounted-volume races, and download steps that do not verify the downloaded artifact.
Why use it?
It addresses failures caused by an asynchronous volume detach colliding with the next mount, and downloads that save an error page as an artifact.

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

ci-flaky-timing-luck scanned grade A 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
