Fine to try.

By DavidSouther/ailly (GitHub) · coding · 16 stars · scanned at commit 3b72cbd

Use when performing research on the current codebase — finding where a symbol is defined, discovering all call sites of a function, understanding a type's structure, tracing interface implementations, or answering any question about what the code does right now at the checked-out commit.

Works with any agent that supports SKILL.md skills.

What this skill can do

Downloads and installs other software

The author does not mention this.

Found in 3 places.

research/skills/codebase/lsp-python.md, line 9- **pylsp** (python-lsp-server): installed via `pip install python-lsp-server`. Wraps multiple analysis backends (pyflakes, rope, jedi).
research/skills/codebase/lsp-python.md, line 10- **pyright**: installed via `npm install -g pyright` or `pip install pyright`. Stronger type inference; preferred for typed codebases.
research/skills/codebase/lsp-setup.md, line 16- Install pyright (`pip install pyright` or `npm install -g pyright`); pylsp (`pip install python-lsp-server`) is the alternative.

Install

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

if [ -e ~/.agents/skills/'codebase' ] || [ -L ~/.agents/skills/'codebase' ]; then echo 'A skill folder named codebase already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/DavidSouther/ailly' "$d" && git -C "$d" checkout --quiet '3b72cbd7d7d6d933ac8e173639b08c833d2a844a' -- 'research/skills/codebase' && mkdir -p ~/.agents/skills && cp -R "$d"/'research/skills/codebase' ~/.agents/skills/'codebase' && 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/'codebase' ~/.claude/skills/'codebase' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
