# potent

> /ˈpōtnt/

A CLI for running (idem)**potent** shell scripts across directories.

Your script runs line-by-line in each directory. If it fails, subsequent runs of the script will pick up with the first command that hasn't run successfully yet.

## Project Status

`potent` is still under active development. It's ready for basic use, but not in production-critical systems.

On the road to `v1.0.0`, expect breaking schema changes, new Operations, small behavior changes, and general stability/productionalization improvements.

Before we reach `1.0.0`, there may be breaking changes in any release; see the CHANGELOG for more details.

## Install

[uv](https://docs.astral.sh/uv/guides/tools/):

```

uv tool install potent

```

[Homebrew](https://brew.sh/):

```

brew install xavdid/projects/potent

```

[pipx](https://pipx.pypa.io/stable/):

```

pipx install potent

```

## Plans

Scripts are run as Plan files. They've got the extension `.plan.json`, but are standard json otherwise.

Plans have two main components:

- a list of folders the Plan will run in
- a list of Operations to perform in those directories

Each Operation is identified by its unique `slug` field.

### Authoring Plan files

Plans are just JSON, so you can write them by hand or generate them using other programs.

If you're handwriting, you can tell VSCode (or any other editor that supports JSON Schema) that `*.plan.json` files must match the schema by adding the following to your settings:

```json
"json.schemas": [
  {
    "fileMatch": ["*.plan.json"],
    "url": "https://raw.githubusercontent.com/xavdid/potent/refs/heads/main/schema.json"
  }
]
```

Specifying the schema will help with autocomplete and flag potential errors.

## Operations

Each of the Operations below describes a single bash command with well-defined (and validated) arguments. If you need more flexibility, check out the [raw command](#rawcommand) Operation.

## FAQ

### Reading validation messages

The error you get when you have an invalid plan file can take a little getting used to. But don't panic! It's actually pretty easy to read.

The most common error you'll get is an invalid slug. It looks like:

```
ValidationError: 1 validation error for Plan
operations.0
  Input tag 'bad-slug' found using 'slug' does not match any of the expected tags: 'git-pull',
'switch-branch', 'git-status', 'git-add', 'git-commit', 'git-push', 'create-pr',
'enable-automerge', 'raw-command' [type=union_tag_invalid, input_value={'comment': None,
'direct...', 'allow_empty': True}}, input_type=dict]
    For further information visit https://errors.pydantic.dev/2.11/v/union_tag_invalid
```

The lines tell you:

1. what failed to validate
2. its json path (in this case, `operations.0`, the first element of the `steps` array)
3. the expected values (which the input doesn't match)

The next most common is missing a required key, which follows a similar pattern:

```
ValidationError: 1 validation error for Plan
operations.0.git-commit.config.message
  Field required [type=missing, input_value={'allow_empty': True}, input_type=dict]
    For further information visit https://errors.pydantic.dev/2.11/v/missing
```

Line 2 is now even more descriptive: `operations[0].config.message` is an error of `type=missing`. More simply, a required key isn't there.

The last common error is an extra key:

```
operations.0.git-commit.config.bad_key
  Extra inputs are not permitted [type=extra_forbidden, input_value=True, input_type=bool]
    For further information visit https://errors.pydantic.dev/2.11/v/extra_forbidden
```

Only expected keys are allowed, and `bad_key` is not expected.

## Demo

Let's say we've got 3 repos, `aardvark`, `badger`, and `camel`. In each one, we want to:

1. ensure we have a clean working directory before proceeding
2. switch to the demo branch
3. create an empty commit
4. push that branch

We can create a [plan](#plans) for that operation, `demo.plan.json`:

```json
{
  "version": "v1",
  "operations": [
    {
      "slug": "clean-status"
    },
    {
      "slug": "switch-branch",
      "config": {
        "branch": "demo"
      }
    },
    {
      "slug": "git-commit",
      "config": {
        "message": "a cool demo commit",
        "allow_empty": true
      }
    },
    {
      "slug": "git-push"
    }
  ],
  "directories": ["/potent-demo/a", "/potent-demo/b", "/potent-demo/c"]
}
```

Let's make sure it parses correctly:

```
% potent summarize demo.plan.json

/Users/david/projects/potent/example.plan.json
├── ⌛ aardvark
│   ├── ⌛ clean-status
│   ├── ⌛ switch-branch
│   ├── ⌛ git-commit
│   └── ⌛ git-push
├── ⌛ badger
│   └── same steps as above
└── ⌛ camel
    └── same steps as above
```

Looks good! Let's give it a run:

```
% potent run demo.plan.json

Oh no! Everything went great in `aardvark`, but it looks like I forgot to initialize the repo in `badger` and `camel` doesn't have the `demo` branch.

I'll run `git init` in `badger` and `git checkout -b demo` in `camel` to get us back on track. Let's run the script again:

```

The ✅ marks show what steps we completed this run, while ☑️ denotes a step we completed on a previous run.

`aardvark` was skipped since it was already done. We made progress in `badger` and `camel` despite erroring out because we can't switch branches without commits and there's nothing to push to.

But, I could resume my script from the middle, skipping any completed operations. This is the power of `potent`!
