90 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Use this standalone skill to build or update a project architecture knowledge base (docs/architecture.md) for multi-end monorepos or any repo with a shared layer, from code evidence, or to check existing rules for staleness, or to write back a newly confirmed convention in one sentence. Do not use for mining coding style only (spec-rule-miner), capturing solved-problem learnings (spec-compound), reviewing diffs (spec-code-review), or writing lint/formatter config.

Works with any agent that supports SKILL.md skills.

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

if [ -e ~/.agents/skills/'spec-project-rules' ] || [ -L ~/.agents/skills/'spec-project-rules' ]; then echo 'A skill folder named spec-project-rules already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/leo-kuang-ai/spec-first' "$d" && git -C "$d" checkout --quiet '74655dc86b1270bb52239e0f8bc9517de7a7071c' -- 'skills/spec-project-rules' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/spec-project-rules' ~/.agents/skills/'spec-project-rules' && 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/'spec-project-rules' ~/.claude/skills/'spec-project-rules' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
