fast-repo-context Semantic code search using sgrep. Use when: exploring code, search code snippets, finding implementations by intent, understanding how features work. Triggers(semantic or similiar meaning): [fast context], [search code], [find where], [how does X work], [understand codebase], [research codebase], [find X], [locate X], [code search], [grep code], [where is], [let me search].

Fast Repo Context

Semantic grep (sgrep script) for code search with natural language queries. Note: it only give code snippets/what/where, not how or code explanations, so your query need to be focus on what/where.

Tool

bash ~/.claude/skills/fast-repo-context/scripts/sgrep.sh --json "<natural language query>"

Safety: Script checks if current directory is a git repo before running to prevent accidental indexing of large/wrong directories.

Options:

  • --json - Structured JSON output (recommended for agents)
  • -n, --limit <N> - Max results (default: 10)
  • -c, --context - Show extra context around matches
  • --glob <GLOB> - Restrict to file patterns (repeatable)
  • --filters <FILTERS> - Filter by metadata (e.g., lang=rust)

When to Use

  • Exploring unfamiliar codebases
  • Finding code by intent/behavior (not just keywords)
  • Understanding how features are implemented
  • Locating related code across files
  • Find something in another project/repo on disk

Workflow

  1. Use sgrep script for semantic search
  2. Read specific files from results for details
  3. (Optional) Query kg from our knowledge graph for additional context

Examples

Find authentication logic

~/.claude/skills/fast-repo-context/scripts/sgrep.sh --json "user login and session management"

Find in another project/repo

Use bash exa --tree -D -L 2 ~/workspace to get all projects in ~/workspace.

cd another-dir-abs-path && ~/.claude/skills/fast-repo-context/scripts/sgrep.sh --json "file upload handling that use api foo/bar"

Find error handling patterns

~/.claude/skills/fast-repo-context/scripts/sgrep.sh --json "how errors are caught and reported to users"

Find API endpoints

~/.claude/skills/fast-repo-context/scripts/sgrep.sh --json "REST endpoints for user profile operations"

Find database queries

~/.claude/skills/fast-repo-context/scripts/sgrep.sh --json "queries that fetch user data with pagination"

Find React hooks usage

~/.claude/skills/fast-repo-context/scripts/sgrep.sh --json "custom hooks for form validation"

With filters

~/.claude/skills/fast-repo-context/scripts/sgrep.sh --json --glob "*.ts" --limit 5 "error handling middleware"

Tips

  • Be descriptive: "function that validates email format" > "email validation"
  • Describe intent: "code that prevents duplicate submissions" > "debounce"
  • Ask questions: "where is the shopping cart total calculated?"
