About this skill

This skill provides troubleshooting steps for Claude Code session issues such as missing sessions, session corruption, and conversations not being found. It is used when `claude -r` reports no conversations to resume, new conversations fail to create session files, or sessions appear in unexpected locations. It is also useful when migrating or recovering large numbers of legacy sessions.

Claude Code Session Recovery Skill

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

When to Use This Skill

Use this skill when:

  • "No conversations found to resume" when running claude -r
  • New conversations not creating session files
  • Sessions appearing in wrong locations (/tmp/ instead of ~/.claude/projects/)
  • Session history missing after environment changes
  • IDE/terminal settings affecting session creation
  • Need to migrate or recover 600+ legacy sessions

Quick Reference

Official Session Storage

Standard Location: ~/.claude/projects/

Structure:

~/.claude/projects/
├── -home-username-my-project/     # Encoded absolute path
│   └── 364695f1-13e7-4cbb-ad4b-0eb416feb95d.jsonl
└── -tmp-another-project/
    └── a8e39846-ceca-421d-b4bd-3ba0eb1b3145.jsonl

Format: One JSON event per line (JSONL), UUID-based filenames

Critical Pitfall: HOME Variable

Problem

Claude Code uses $HOME environment variable to determine session storage location. If $HOME is incorrect, sessions go to wrong directory or disappear.

Symptoms

  • claude -r shows "No conversations found to resume"
  • New conversations work but files don't appear in expected location
  • Sessions found in /tmp/ or other unexpected paths
  • Works on one machine but not another

Diagnosis

/usr/bin/env bash << 'PREFLIGHT_EOF'
# Step 1: Check current HOME
echo "Current HOME: $HOME"

# Step 2: Check system expectation
echo "Expected HOME: $(getent passwd $(whoami) | cut -d: -f6)"

# Step 3: Find where Claude is actually writing
find /tmp -name "*.jsonl" -path "*/.claude/projects/*" 2>/dev/null
PREFLIGHT_EOF

Troubleshooting

Issue Cause Solution
"No conversations found" Wrong HOME variable Verify $HOME matches expected user directory
Sessions in /tmp/ HOME set incorrectly Fix HOME in shell profile, restart terminal
Session files missing Disk space or permissions Check ~/.claude/projects/ permissions and disk
Wrong project sessions shown Path encoding mismatch Check encoded path matches current working directory
Sessions not persisting File system issues Verify write permissions to ~/.claude/projects/
IDE sessions separate Different HOME per environment Ensure consistent HOME across terminal and IDE
Legacy sessions not visible Migration not complete See migration section in TROUBLESHOOTING.md
UUID filename corruption Incomplete writes Check for partial .jsonl files, remove corrupt ones

Post-Execution Reflection

After this skill completes, check before closing:

  1. Did the command succeed? — If not, fix the instruction or error table that caused the failure.
  2. Did parameters or output change? — If the underlying tool's interface drifted, update Usage examples and Parameters table to match.
  3. Was a workaround needed? — If you had to improvise (different flags, extra steps), update this SKILL.md so the next invocation doesn't need the same workaround.

Only update if the issue is real and reproducible — not speculative.
