Quick Start¶
In 3 minutes you'll generate a knowledge bundle from any codebase and look up any function, class, or dependency — no LLM, no API key, no setup.
1. Generate a bundle¶
Run okf generate from your project root — it auto-detects the source directory:
cd my_project
okf generate
Or specify paths explicitly:
okf generate ./my_project ./okf_bundle
Auto-detection walks up the directory tree looking for project markers (pyproject.toml, Cargo.toml, package.json, go.mod, .git/, etc.) across all languages. If nothing is found, it uses the current directory.
This scans all recognized files using tree-sitter AST parsers (17 languages) and writes a structured knowledge bundle to ./okf_bundle/.
What you get: - Every function, class, method, and module as a concept card - Every dependency extracted from manifest files - Cross-reference edges (calls, called-by, imports, depends-on) - Pure markdown — diff cleanly, version alongside code
Example output:
Class 12
Function 48
Module 14
Dependency 8
Interface 3
Enum 2
────────────────────────
TOTAL 87
2. Look up any concept¶
okf lookup --bundle ./okf_bundle MyFunction
Returns the full concept card — signature, parameters, docstring, return type, callers, callees, and source location — in milliseconds.
Filter by type:
okf lookup --bundle ./okf_bundle --type Function
okf lookup --bundle ./okf_bundle --type Class
okf lookup --bundle ./okf_bundle --type Dependency
Filter by language or ecosystem:
okf lookup --bundle ./okf_bundle --tag lang:python
okf lookup --bundle ./okf_bundle --tag ecosystem:pip
Fuzzy search — camelCase, snake_case, acronyms:
okf lookup --bundle ./okf_bundle repo # Finds UserRepository, OrderRepo
okf lookup --bundle ./okf_bundle calc # Finds Calculator
okf lookup --bundle ./okf_bundle ur # Acronym match: UserRepository
JSON output for programmatic use:
okf lookup --bundle ./okf_bundle --json MyClass
3. Browse visually¶
Static visualization¶
okf visualize ./okf_bundle
# Opens an interactive HTML graph in your browser
Live dashboard (FastAPI)¶
# Install the dashboard extra first:
pip install "okf-generator[dashboard]"
okf dashboard ./okf_bundle --open
# Launches at http://127.0.0.1:8700
The dashboard provides:
- Search — full-text search with type and language filters
- Detail view — signature, params, docstring, source, tags, related links
- Interactive graph — visual dependency graph per concept
- REST API — all data available at /api/ endpoints
4. Diff and track changes¶
# Generate from two versions
okf generate ./project_v1 /tmp/v1
okf generate ./project_v2 /tmp/v2
# See what changed
okf diff /tmp/v1 /tmp/v2 --compact
# See dependency impact
okf diff /tmp/v1 /tmp/v2 --impact
The --impact flag traces changed dependencies to affected modules and their functions/classes — critical for CI/CD pipelines.
5. Use from Python¶
from okf.generator import scan_codebase, write_bundle
from okf.lookup import load_bundle, search
from pathlib import Path
# Scan a codebase
concepts = scan_codebase(Path("./my_project"))
print(f"Extracted {len(concepts)} concepts")
# Write a bundle
write_bundle(concepts, Path("./okf_bundle"), "my_project", ["initial scan"])
# Load and search
bundle = load_bundle(Path("./okf_bundle"))
results = search(bundle, tokens=["PaymentService"])
print(results[0].title) # "PaymentService"
print(results[0].type) # "Class"
print(results[0].signature) # "class PaymentService"
6. Set up for AI agents¶
One command installs okf-generator into your preferred agent:
okf install claude # Claude Code skill
okf install cursor # Cursor rules
okf install copilot # GitHub Copilot
okf install opencode # OpenCode /lookup command
okf install all # All of the above
After installation, when you ask your agent about any concept in your codebase, it will automatically run okf lookup instead of reading entire files — saving 80-95% tokens.
