gnoma

Provider-agnostic agentic coding assistant in Go. Named after the northern pygmy-owl (Glaucidium gnoma). Agents are called elfs (elf owl).

Build

make build          # ./bin/gnoma
make install        # $GOPATH/bin/gnoma

Providers

Anthropic

export ANTHROPIC_API_KEY=sk-ant-...
./bin/gnoma --provider anthropic
./bin/gnoma --provider anthropic --model claude-opus-4-5-20251001

Integration tests hit the real API — keep a key in env:

go test -tags integration ./internal/provider/...

---

OpenAI

export OPENAI_API_KEY=sk-proj-...
./bin/gnoma --provider openai
./bin/gnoma --provider openai --model gpt-4o

---

Mistral

export MISTRAL_API_KEY=...
./bin/gnoma --provider mistral

---

Google (Gemini)

export GEMINI_API_KEY=AIza...
./bin/gnoma --provider google
./bin/gnoma --provider google --model gemini-2.0-flash

---

Ollama (local)

Start Ollama and pull a model, then:

./bin/gnoma --provider ollama --model gemma4:latest
./bin/gnoma --provider ollama --model qwen3:8b     # default if --model omitted

Default endpoint: http://localhost:11434/v1. Override via config or env:

# .gnoma/config.toml
[provider]
default = "ollama"
model   = "gemma4:latest"

[provider.endpoints]
ollama = "http://myhost:11434/v1"

---

llama.cpp (local)

Start the llama.cpp server:

llama-server --model /path/to/model.gguf --port 8080 --ctx-size 8192

Then:

./bin/gnoma --provider llamacpp
# model name is taken from the server's /v1/models response

Default endpoint: http://localhost:8080/v1. Override:

[provider.endpoints]
llamacpp = "http://localhost:9090/v1"

---

Config

Config is read in priority order:

1. ~/.config/gnoma/config.toml — global
2. .gnoma/config.toml — project-local (next to go.mod / .git)
3. Environment variables

Example .gnoma/config.toml:

[provider]
default = "anthropic"
model   = "claude-sonnet-4-6"

[provider.api_keys]
anthropic = "${ANTHROPIC_API_KEY}"

[provider.endpoints]
ollama   = "http://localhost:11434/v1"
llamacpp = "http://localhost:8080/v1"

[permission]
mode = "auto"   # auto | accept_edits | bypass | deny | plan

Environment variable overrides: GNOMA_PROVIDER, GNOMA_MODEL.

Testing

make test               # unit tests
make test-integration   # integration tests (require real API keys)
make cover              # coverage report → coverage.html
make lint               # golangci-lint
make check              # fmt + vet + lint + test

Integration tests are gated behind //go:build integration and skipped by default.
