FlowJet
FlowJet is a friendly one-shot coding agent for your terminal. Ask a question in plain English, get an answer — no UI, no context-switching.
fj explain this repo # the short alias for flowjet-agent
fj -f what did we decide last time # continue the last conversation
fjf what did we decide last time # alias of fj -f
It runs on soothe-nano — tools, skills, MCP, subagents, and progressive loading — with SQLite persistence so every conversation is resumable.
Package: flowjet-agent · aliases:
fj,fjf(=-f) · Runtime: soothe-nano · Naming details: docs/naming.md
Install
pip install flowjet-agent
# or
uv tool install flowjet-agent
Requires Python 3.11+.
Configure
Option A — Local model (guided setup):
fj setup
This walks you through an OpenAI-compatible endpoint (Ollama, LM Studio, vLLM, …) and writes the basics to ~/.soothe/config/nano.yml.
Option B — Cloud (no config file needed):
export OPENAI_API_KEY=sk-...
fj summarize README.md
Without a nano.yml, FlowJet falls back to OPENAI_API_KEY or ANTHROPIC_API_KEY.
Doctor
Check whether your machine is ready to run fj (tool binaries, providers, observability):
fj doctor # quick check
fj doctor --deep # thorough check
fj doctor --live-llm # actually call the model
fj doctor --format json # machine-readable
Conversations
Threads persist in SQLite, so you can pick up where you left off — continue the latest, jump to a specific one, or list them:
fj -f and now add tests # continue this project's latest active thread
fj -t abc123 continue from here # continue a specific thread
fj -l # list recent threads
-f is scoped to the project you are in — the git repo root, or the current directory when it is not a repo — so parallel work in other checkouts never hijacks your thread. fj -l still lists every thread; pick one up from anywhere with -t ID.
Flags
fj [options] [--] <query...>
| Flag | Meaning |
|---|---|
-f / --follow |
Continue the latest active thread in this project directory |
-t ID / --thread |
Continue (or pin) a specific thread (overrides -f) |
-l / --list |
List recent threads (newest first) |
-n NUM |
How many threads -l shows (0 = all) |
-c PATH / --config |
Use an alternate nano.yml |
-w DIR / --workspace |
Workspace root |
--no-stream |
Wait for the full answer instead of streaming |
-v / --verbose |
Mirror tool calls on stderr |
-tand-fcan be combined;-twins (explicit id overrides follow).
Shell completion is AI-assisted — it predicts natural-language intents, not just flags:
eval "$(fj completion zsh)" # or: fj completion bash
Extend
Skills
FlowJet ships with AgentSkills (planning, TDD, debugging, document tools, MCP builder, and more). Add your own in nano.yml:
skills:
- ~/.soothe/skills/my-reviewer
- ./skills/deploy
Each skill is a SKILL.md with frontmatter; progressive loading keeps the catalog compact and loads skills on demand.
MCP servers
Connect any Model Context Protocol server:
mcp_servers:
- name: filesystem
transport: stdio
command: npx
args: ["-y", "@modelcontextprotocol/server-filesystem", "/tmp"]
With defer: true (the default), MCP tools activate on demand.
Development
git clone https://github.com/caesar0301/flowjet-agent.git
cd flowjet-agent
make sync-dev
make test
make lint
CI runs format, lint, and tests on Python 3.11–3.13; releases go GitHub Release → PyPI.
