Production-tested skills for Claude Code. Drop-in markdown files that teach Claude specific workflows.
These are patterns I built for my own daily work and generalized for anyone to use. They work with Claude Code out of the box and follow the agentskills.io standard where applicable.
| Skill | Commands | What it solves |
|---|---|---|
| Session Management | /start, /end, /update, /today |
Claude Code has no memory between sessions — this adds it |
| Reconcile | /reconcile |
Parallel sessions cause state drift — this detects it |
| Recover | /recover |
Crashed sessions leave orphaned worktrees — this cleans them |
| Skill Creator | /skill-creator |
Writing skills from scratch is slow — this scaffolds them |
Prerequisites: Claude Code installed, a project with a .claude/commands/ directory.
# 1. Copy a skill into your project
cp -r session-management/SKILL.md your-project/skills/session-management/SKILL.md
# 2. Create a command routing file
cat > your-project/.claude/commands/start.md << 'EOF'
---
name: start
description: Start a session — load state and get a briefing
---
Load and follow the instructions in `skills/session-management/SKILL.md`, section "/start — Begin Session".
EOF
# 3. Use it
# Type /start in Claude CodeRepeat for each skill/command you want. See each skill's SKILL.md for the full setup details.
A system of four commands (/start, /end, /update, /today) that give Claude Code memory across conversations. Maintains state files so every session picks up where the last one left off.
/start— Load project state, check what changed, get a briefing/end— Auto-extract session summary, update state, check for uncommitted work/update— Mid-session checkpoint (quick save)/today— Morning heartbeat: staleness check, deadlines, memory curation
Includes setup guide with the required file structure and minimal starter templates.
Tripwire check for multi-session drift. Scans recent commits, state files, and cross-references for inconsistencies caused by parallel Claude Code sessions.
Use after merging worktree branches, after crashes, or whenever something feels off.
Scan for orphaned worktrees and stale branches left behind by crashed or abandoned sessions. Read-only by default — reports findings and waits for your approval before any cleanup.
Meta-skill: describe what you want a skill to do in plain language, and it generates the SKILL.md, command routing file, and CLAUDE.md additions. Good for bootstrapping new skills quickly.
- Copy the
SKILL.mdfrom the skill directory you want - Place it in your project (e.g.,
skills/session-management/SKILL.md) - Reference it in your
CLAUDE.mdor.claude/commands/directory - Use the slash command (e.g.,
/start,/end,/reconcile)
- Clone this repo or copy the skill directories into your project
- Add command routing files to
.claude/commands/for each skill:
---
name: start
description: Start a session — load state and get a briefing
---
Load and follow the instructions in `skills/session-management/SKILL.md`, section "/start — Begin Session".- Add the commands to your
CLAUDE.mdslash command table
These skills follow the agentskills.io format and work with Cursor, Windsurf, Cline, OpenHands, and 40+ other AI coding tools. Check each tool's docs for how to load custom instruction files.
