Check Prior Work

Category: Engineering · Sub-category: code-quality · Last updated: 2026-05-21

Use BEFORE starting any non-trivial coding task in an existing project — feature work, refactors, bugfixes, or "look at this codebase" requests. Triggers when the user asks to add/change/fix something inside a repo (e.g. "add X to the dashboard", "refactor the auth flow", "fix the bug in cost calculation", "why is this slow"). Surfaces recent prior sessions in the same project so the agent isn't redoing work or contradicting decisions made in past sessions.

What this skill does

Check Prior Work is a community-contributed Claude Code skill in the code-quality sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/check-prior-work/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Check Prior Work Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
