Frequently Asked Questions About Vinzenz 'evilissimo' Feenstra

FAQPage Schema
What tasks can I accomplish with vinzenz's skills?▼

You can triage git diffs by risk, find which tests a change affects, estimate file read costs before loading them, query coding-agent session logs, manage GitHub and GitLab issues and pipelines, control Podman containers, and capture design decisions as ADRs and glossaries.

Who are these skills designed for?▼

Software developers and coding-agent operators working in git repositories who need deterministic, token-efficient command-line utilities. The author's background is C++, Go, and Python development, and the skills target engineers running agents like Copilot CLI, Claude Code, Codex, and opencode.

How do I install and run these skills?▼

The workflows skill links the toolbox into one selected repository without global availability, and the toolbox skill governs adding commands and wiring dependencies into install.sh. Skills run as command-line utilities inside the current repo checkout.

What prerequisites do these skills require?▼

A local git repository is the core requirement, since most skills operate on diffs, blame, churn, and committed ledgers. Specific skills wrap the GitHub CLI, GitLab CLI, or Podman CLI, and agent-log and agent-pager require local Copilot CLI, Claude Code, Codex, or opencode session stores.

Do these skills replace language servers or full test suites?▼

No. The xref skill explicitly states it is a cached heuristic lexical index, not a substitute for an LSP or ast-grep when correctness matters. Similarly, affected selects which tests are worth running rather than replacing the suite, and diag normalizes build output under enforced timeouts.
