harness-binary-spelunking skillA

harness-binary-spelunking is agent-read markdown (skill) from technicalpickles/pickled-claude-plugins: Use when investigating an agent-harness CLI's internals (Claude Code, codex, opencode, or similar): extracting the system prompt or tool descriptions, finding what code path produces a specific UI message, decoding minified function names or Rust symbols, understanding undocumented config keys, or otherwise spelunking a shipped binary (or its pinned source) to figure out how the tool actually behaves..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add technicalpickles/pickled-claude-plugins/harness-binary-spelunking@git:20260820.f29e5a0
Exact content
mdr add technicalpickles/pickled-claude-plugins/harness-binary-spelunking@sha256:9e34929c00f61452

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
