jev-audit SKILL.md skillA
jev-audit from onewave-ai/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Audit a codebase for LLM calls that are really classifications in disguise, then produce a costed swap plan for a System One model. Use when asked to cut AI inference cost or latency, when scoping a performance engagement for a client, when reviewing an agent loop that feels slow, or when asked "where could we use Jev here". Produces a ranked table of candidates with measured latency and dollar deltas.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Inference-cost audit
Most production LLM calls return a **label**, not prose — a route, a score, a yes/no, a
category. Those calls pay for autoregressive generation they do not use. This audit finds
them and prices the swap.
Deliverable: a ranked table of candidates with measured deltas. Sellable as a OneWave
engagement; same shape as `marketing-brain` — a repeatable audit run per client.
## 1. Find the candidates
Search for LLM calls, then filter to the ones whose output is a label:
```bash
grep -rnE "messages\.create|chat\.completions|generateText|\.invoke\(|anthropic\.|openai\." \
--include=*.{ts,tsx,js,py} . | grep -v node_modules
```
A call is a candidate when **all** of these hold:
- the prompt asks for one of a **known, finite** set of answers (≤255)
- the caller **parses** the response — JSON.parse, a regex, an enum lookup, `.trim()`
- nothing downstream shows a human the model's reasoning
- it runs **often**, or a user waits on it
Strong signals in the prompt text: "respond with only", "return JSON", "classify",
"choose one of", "rate from 1 to", "answer yes or no", "do not explain".

How to install
mdr add onewave-ai/claude-skills/jev-audit@sha256:96373e3f023c822bThe line at the top of this page pins the label git:20260921.1fa6175, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
