combfind 0.1.12

Queryable concept map of a codebase for LLM coding agents

combfind

Give an AI agent a codebase. combfind tells it where to look.

combfind builds a local index of a repository so an agent can find the right files and functions for a task with a plain-text query, without reading the entire codebase.

Install

For local LLM inference:

pip3 install "combfind[llm]" \
  --extra-index-url https://abetlen.github.io/llama-cpp-python/whl/cpu

Download a model (one-time, ~2 GB):

combfind download-model

For a remote OpenAI-compatible API instead:

pip3 install "combfind[openai]"

Usage

# Index a repository (local LLM, auto-detected model)
combfind init /path/to/repo --db repo.db

# Index using a remote OpenAI-compatible API
COMBFIND_LLM_API_KEY=sk-... COMBFIND_LLM_MODEL=gpt-4o-mini \
  combfind init /path/to/repo --db repo.db --llm-mode openai

# Query it
combfind query "how does authentication work" --db repo.db
combfind query "where are database migrations" --db repo.db --format json

Init options

Flag	Default	Description
--db	<repo_path>/.combfind.db	Output path
--llm-model	auto-detected	Path to a GGUF model file (local mode only)
--llm-mode	local	LLM backend: local (llama.cpp) or openai (OpenAI-compatible API)
--exclude-paths	-	Paths to skip relative to repo root (repeatable)
--exclude-regex	-	Regex matched against file paths to skip

Query options

Flag	Default	Description
--db	.combfind.db	Database to query
--top-k	5	Number of results to return
--format	text	Output format: text or json

Environment variables

Variable	Default	Description
COMBFIND_LOG_LEVEL	info	Log verbosity: debug, info, warning, error
COMBFIND_LLM_BASE_URL	-	Base URL for OpenAI-compatible API (e.g. https://api.openai.com/v1)
COMBFIND_LLM_API_KEY	-	API key for the remote LLM
COMBFIND_LLM_MODEL	gpt-4o-mini	Model name to use with --llm-mode openai

Using a remote LLM API

Pass --llm-mode openai to use any OpenAI-compatible API instead of a local model. Configure it with environment variables:

export COMBFIND_LLM_BASE_URL=https://api.openai.com/v1
export COMBFIND_LLM_API_KEY=sk-...
export COMBFIND_LLM_MODEL=gpt-4o-mini

combfind init /path/to/repo --db repo.db --llm-mode openai

Any API that speaks the OpenAI chat completions format works, including:

• OpenAI — set COMBFIND_LLM_BASE_URL=https://api.openai.com/v1
• Ollama — set COMBFIND_LLM_BASE_URL=http://localhost:11434/v1 and COMBFIND_LLM_API_KEY=ollama
• LM Studio — set COMBFIND_LLM_BASE_URL=http://localhost:1234/v1
• Any other OpenAI-compatible server — point COMBFIND_LLM_BASE_URL at its /v1 endpoint

--llm-model is ignored in openai mode; the model is selected via COMBFIND_LLM_MODEL.

Supported languages

Python, Go. More languages can be added via tree-sitter grammars.
