# firefly-cli

A command-line tool that lets an LLM agent (and you) interact with a
[Firefly III](https://www.firefly-iii.org/) instance over its REST API.
Python package, stdlib only, exposing the `firefly` command.

## Install

```bash
pip install -e .
```

Requires Python 3.11 or newer. No third-party runtime dependencies.

### Bash completion

A completion script lives at `completions/firefly.bash`. Enable it by sourcing
it from your shell profile, or install it system-wide:

```bash
# per-user: add to ~/.bashrc
source /path/to/firefly-cli/completions/firefly.bash

# or system-wide
sudo cp completions/firefly.bash /usr/share/bash-completion/completions/firefly
```

It is generated from the command registry, never hand-edited. Regenerate after
adding or changing commands:

```bash
python scripts/gen_completion.py > completions/firefly.bash
```

## Configuration

Provide your Firefly III URL and a personal access token in either way:

- Run `firefly auth set` and follow the prompts (stored in a local TOML file).
- Or set environment variables `FIREFLY_URL` and `FIREFLY_TOKEN`, which take
  precedence over the config file.

## Commands

Run `firefly --help` for the full list. Current commands (v0.4.1):

```
firefly auth set                 write URL and token to the config file
firefly auth test                verify connectivity and token

firefly account list [--type T]  list accounts (filter: asset, expense, ...)
firefly account get <name|id>    show one account
firefly account balance <name>   show an account balance
firefly account create <name> --type asset|expense|revenue
        [--opening-balance N] [--currency CODE]

firefly tx add <amount> --from <acct> --to <acct> [--desc T]
        [--date YYYY-MM-DD] [--category C] [--tags a,b] [--type T]
        [--budget B]
firefly tx list [--since D] [--until D] [--account A] [--limit N]
firefly tx get <id>              show one transaction
firefly tx search <query>        search transactions by Firefly query string
firefly tx edit <id> [--amount N] [--date D] [--desc T] [--from A]
        [--to A] [--category C] [--tags a,b] [--type T]
firefly tx delete <id> --yes     delete one transaction (requires --yes)

firefly budget list [--start D] [--end D]
        list budgets with spent for a period (default: current month)
firefly budget create <name> [--active|--inactive] [--currency CODE]
        [--auto-budget-amount N]
        [--auto-budget-period daily|weekly|monthly|quarterly|half_year|yearly]
        [--auto-budget-type reset|rollover|adjusted|none]
firefly budget enable <name|id>  mark a budget active
firefly budget disable <name|id> mark a budget inactive
firefly budget delete <name|id> --yes
firefly budget limit-list <name|id>
firefly budget limit-set <name|id> --amount N [--start D] [--end D]
        [--currency CODE]

firefly category list
firefly tag list
```

The command set grows over time; see `CLAUDE.md` for how to add one.

## For agents

- Output is JSON by default. Pass `--human` for aligned tables.
- Exit code is 0 on success, 1 on any error; errors print as
  `{"error": "..."}` on stderr.
- Account arguments accept names, which are resolved to IDs. An ambiguous or
  unknown account is a hard error listing the candidates, never a silent guess.
- Categories and tags are not resolved: `tx add --category`/`--tags` pass the
  names straight to Firefly, which creates them if new. Accounts are never
  auto-created; use `account create`.
- `tx add` infers the transaction type from the account types (asset to expense
  is a withdrawal, revenue to asset is a deposit, asset to asset is a transfer).
  Override with `--type`. `tx edit` changes only the fields you pass.
- Budgets are managed by name or id. `budget list` reports spent per budget for
  a period; `budget limit-set` sets a spending limit over a date range.
  `budget delete` and `tx delete` require `--yes`.

## For agents (skill)

[`SKILL.md`](SKILL.md) is an agent-operating guide for driving `firefly`: the
JSON/exit-code contract, name resolution, transaction-type inference, task
recipes, and gotchas. It carries skill frontmatter, so it can be symlinked into
a Claude Code skills directory to auto-activate on Firefly III and personal
finance tasks.
