Trace harness generation (Phase 2.5). Use when: (1) instrumenting a system's source code to emit NDJSON traces for TLA+ trace validation, (2) writing test scenarios that exercise protocol code paths, (3) producing the first batch of traces from instrumented tests.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'harness-generation' ] || [ -L ~/.agents/skills/'harness-generation' ]; then echo 'A skill folder named harness-generation already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/specula-org/Specula' "$d" && git -C "$d" checkout --quiet 'e616bdae7b4eea622f8248ead79b9f8937c29fe7' -- 'skills/harness-generation' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/harness-generation' ~/.agents/skills/'harness-generation' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'harness-generation' ~/.claude/skills/'harness-generation' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
