textstack: Skill for Claude Code

.claude/skills/run-prod-eval/SKILL.md

run-prod-eval is a skill for Claude Code from mrviduus/textstack. It costs 56 tokens per session (632 once invoked), scanned A, original, AGPL-3.0.

A procedure for running an AI evaluation gate against a production system. The evaluation scores a feature using tool-call accuracy and judged test suites with real production access.

In plain words
What is it for?
Use it to evaluate production behavior when you have the required OpenAI key, test corpus, and administrator session.
Why use it?
It checks whether a feature meets its definition of done in production rather than relying only on local or CI results.

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

run-prod-eval 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 3d 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.

Makes network callslowCapability

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

2. Confirm the endpoint exists (not 404): `curl -s -o /dev/null -w '%{http_code}'` POST unauth → expect 401.

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.
