Use when existing code has untestable dependencies that prevent writing tests -- direct construction of collaborators, static or global function calls, tight coupling to external systems, or singleton access patterns. Specifically for identifying substitution points (seams) that make legacy or tightly-coupled code testable without editing at the call site. Do NOT use for greenfield TDD (see tdd), general test writing patterns (see testing), or refactoring already-tested code (see refactoring).

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/'finding-seams' ] || [ -L ~/.agents/skills/'finding-seams' ]; then echo 'A skill folder named finding-seams already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/citypaul/.dotfiles' "$d" && git -C "$d" checkout --quiet 'cd4028d57d6e4e95814f7b8ee55ca13c23a9c2f0' -- 'claude/.claude/skills/finding-seams' && mkdir -p ~/.agents/skills && cp -R "$d"/'claude/.claude/skills/finding-seams' ~/.agents/skills/'finding-seams' && 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/'finding-seams' ~/.claude/skills/'finding-seams' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
