Overview

This skill indexes and searches Claude Code conversation history with a hybrid text+semantic engine to help you rediscover past solutions, commands, and related sessions. It surfaces concise results and session IDs so you can quickly review or reopen prior work. Use it to recall exact commands, revisit implementation patterns, or find similar past projects.

How this skill works

The tool runs a hybrid search combining keyword matching and semantic vectors across all indexed Claude Code sessions. You can filter by tool type (Bash, Read, Edit, Grep, etc.), time range, project, and error-only results. Commands return session IDs and compact summaries so you can open a session or expand context as needed.

When to use it

• When you need to find a past implementation or copy a prior solution.
• When you want to recall commands you ran (e.g., git, docker, cargo).
• When exploring similar sessions or related work to avoid duplicating effort.
• When debugging recurring errors and you want prior troubleshooting steps.
• When auditing recent activity across projects or sessions.

Best practices

• Use --compact to get one-line, token-efficient results for fast scanning.
• Prefer --mode semantic for conceptual, “how-to” or pattern searches; use --mode text for exact error messages or keywords.
• Filter by tool with -t (e.g., Bash) to narrow results to command snippets.
• Apply time filters (--since 1d, 1w, or specific date) to focus recent work.
• Chain commands: search → capture session ID → session <id> --summary → session <id> --limit N for full context.

Example use cases

• Find a prior authentication implementation: glhf search "authentication" --mode semantic --compact
• Rediscover a command you ran: glhf search "docker" -t Bash --compact
• Review recent sessions to catch up: glhf recent -l 10
• Inspect a specific session quickly: glhf session abc123 --summary then glhf session abc123 --limit 50
• Find sessions with errors from the last day: glhf search "error" --errors --since 1d --compact
