patcher

patcher is a skill for Claude Code, Codex from wundercorp/builderstudio-skills. It costs 74 tokens per session (2,872 once invoked), scanned B, original, no licence file.

A workflow for finding, assessing, fixing, and checking security weaknesses in software and its build process. A CVE is a publicly recorded software vulnerability, and supply-chain risk comes from unsafe dependencies or tools used to build an application.

In plain words
What is it for?
Use it to investigate Docker vulnerabilities, dependency CVEs, zero-day mitigations, frontend and backend security issues, and insecure build-pipeline settings.
Why use it?
It helps identify exploitable problems while keeping the codebase and existing behavior intact.

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

patcher scanned grade B with 2 findings 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 7d 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.

Downloads and executes remote codemediumSupply chain

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

- `curl | sh`, `wget | sh`, remote `ADD`, unauthenticated downloads, and unsigned binaries.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

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.
