When & Why to Use This Skill

glhf is a specialized search utility designed for Claude Code that acts as a long-term memory layer for developers. By leveraging hybrid search—combining exact text matching with semantic understanding—it allows users to instantly retrieve past solutions, recall specific terminal commands, and explore related work across different sessions. This skill significantly enhances developer productivity by eliminating the need to repeat complex tasks or manually dig through log files, ensuring that valuable insights from previous AI interactions are always accessible.

Use Cases

  • Command Recovery: Quickly find and reuse complex Bash, Docker, or Git commands executed in previous sessions without having to remember the exact syntax.
  • Solution Retrieval: Use semantic search to locate how a specific bug or architectural challenge was solved weeks ago, even if you don't remember the exact keywords used.
  • Contextual Onboarding: When returning to an old project, use the 'recent' and 'summary' commands to get a high-level overview of past progress and technical decisions.
  • Error Debugging: Filter past conversation history specifically for error logs and their corresponding fixes to resolve recurring issues faster.
  • Knowledge Discovery: Find related sessions and projects to identify patterns or shared logic across different codebases in your development environment.

glhf

Search your Claude Code conversation history using hybrid search (text + semantic).

Quick Examples

# Find past solutions (semantic search)
glhf search "authentication" --mode semantic --compact

# Find commands you've run
glhf search "docker" -t Bash --compact

# Check recent sessions
glhf recent -l 10

# Get session overview then dive deeper
glhf session abc123 --summary
glhf session abc123 --limit 50

Commands

Command Purpose
search Find content across all sessions
session View a specific session's content
related Find sessions similar to a given one
recent List recent sessions
projects List all indexed projects
status Show index stats
index Rebuild the search index

Key Search Flags

Flag Purpose
--compact One-line output, fewer tokens
--mode semantic Conceptual search (how to X, patterns)
--mode text Exact keyword matching
-t Bash Filter by tool (Bash, Read, Edit, Grep, etc.)
-p . Filter to current project
--since 1d Time filter (1h, 2d, 1w, or date)
--errors Only show error results
--show-session-id Include session IDs for follow-up

Find past solutions:

glhf search "problem description" --mode semantic --compact
glhf search "specific keyword" --show-session-id --compact
glhf session <id> --summary

Recall commands:

glhf search "git rebase" -t Bash --compact
glhf search "cargo" -t Bash --since 1w --compact

Find similar work:

glhf recent -l 10
glhf related <session-id> --limit 5

Debug past errors:

glhf search "error" --errors --since 1d --compact

Tips

  1. Always use --compact - significantly reduces output tokens
  2. Use --mode semantic for "how to" questions and conceptual searches
  3. Use --mode text for exact keywords and error messages
  4. Chain commands: search → get session ID → view summary → get full context
  5. Current project/session auto-excluded when running inside Claude Code
  6. Use -p . to filter to current project when you want to include it
  7. Use glhf <command> --help for complete option documentation
