skillnet 0.3.0

Reconcile and manage local AI skill mirrors; calibration data for the multi-phase-plan skill.
Documentation
# skillnet

`skillnet` is a CLI for reconciling local AI skill directories into a checked-in mirror, editing mirrored skills, syncing selected mirror state back to live agent directories, and recording calibration data for `multi-phase-plan`.

The supported interface in `0.2.0` is the `skillnet` binary. This crate does not commit to a stable embeddable Rust API yet.

## Install

```sh
cargo install skillnet
```

For a source checkout:

```sh
cargo install --path .
```

### Nix Home Manager

Add the flake input and import the module:

```nix
inputs.skillnet.url = "git+ssh://git@codeberg.org/caniko/skillnet.git";

# In your Home Manager config:
imports = [ inputs.skillnet.hmModules.default ];
programs.skillnet = {
  enable = true;
  settings = {
    mirror_root = "/home/alice/skills-mirror";
    scopes = [
      {
        name = "global";
        sources = [ "/home/alice/.claude/skills" ];
      }
    ];
  };
  database = {
    backend = "postgres";
    urlFile = config.age.secrets.skillnet-pg-url.path;
  };
};
```

The module is exported as both `hmModules.default` and `hmModules.skillnet`.
It installs `skillnet` on `PATH`. When `settings` is declared, the module
renders `skillnet.toml` and exports `SKILLNET_CONFIG`, `SKILLNET_CATALOG_CONFIG`,
and `SKILLNET_MIRROR_ROOT` for the CLI. Without `settings`, you can still drop
your own TOMLs and point `programs.skillnet.configFile` at them. When SQLite is
selected, the module also creates the runtime data directory and exports
`skillnet_DATA_DIR` and `SKILLNET_DATA_DIR`.

If you also want the module to define where the `ai-skills` checkout lives,
set `skillsRoot`. On atlas, that path is:

```nix
programs.skillnet.skillsRoot = "/data/nvme0/can/Projects/ai-skills";
```

When configured, the module exports `AI_SKILLS_REPO` and warns if the checkout
directory is missing. `skillsRoot` points at the skills checkout;
`dataDir` remains skillnet's runtime database and cache location.

Postgres is the default calibration backend and requires a connection URL.
SQLite is also supported by selecting it explicitly:

```nix
programs.skillnet = {
  enable = true;
  package = inputs.skillnet.packages.${pkgs.system}.skillnet;

  database = {
    backend = "sqlite";
  };
};
```

The Postgres backend is included in default builds. If you override
`programs.skillnet.package` with a custom `--no-default-features` build, choose
a package that includes the `postgres` feature when using the Postgres backend.

The `database.url` value is written into the Nix store. For production secrets,
prefer `database.urlFile`, which reads the Postgres URL from a file at shell
initialization time.

Options:

- `programs.skillnet.dataDir` defaults to `${config.xdg.dataHome}/skillnet`.
  This is skillnet's runtime database and cache location.
- `programs.skillnet.skillsRoot` optionally sets the `ai-skills` checkout root
  and exports it as `AI_SKILLS_REPO`; atlas uses
  `/data/nvme0/can/Projects/ai-skills`.
- `programs.skillnet.database.backend` selects `sqlite` or `postgres` and
  defaults to `postgres`.
- `programs.skillnet.database.path` optionally sets the SQLite database path;
  when unset, calibration data lives at
  `<dataDir>/multi-phase-plan/calibration.sqlite`.
- `programs.skillnet.database.url` sets `SKILLNET_DATABASE_URL` and is required
  when `programs.skillnet.database.backend = "postgres"` and `urlFile` is
  unset.
- `programs.skillnet.database.urlFile` reads a Postgres URL from a file at
  shell initialization time.
- `programs.skillnet.settings` and `programs.skillnet.catalogSettings` render
  `skillnet.toml` and `skillnet.catalog.toml` from Nix.
- `programs.skillnet.configFile` and `programs.skillnet.catalogConfigFile`
  point the CLI at user-managed TOML files.
- `programs.skillnet.package` overrides the package. If `pkgs.skillnet` is not
  available in your package set, use
  `inputs.skillnet.packages.${pkgs.system}.skillnet`.

## Storage backends

Postgres is the default calibration backend:

```toml
[database]
url = "postgres://skillnet@localhost/skillnet"
```

SQLite is available by selecting it explicitly:

```toml
[database]
backend = "sqlite"
path = "/home/alice/.local/share/skillnet/multi-phase-plan/calibration.sqlite"
```

The `path` key is optional. Without it, `skillnet` uses
`$skillnet_DATA_DIR/multi-phase-plan/calibration.sqlite`,
`$SKILLNET_DATA_DIR/multi-phase-plan/calibration.sqlite`, or
`$XDG_DATA_HOME/skillnet/multi-phase-plan/calibration.sqlite`.

Select Postgres with an environment variable:

```sh
export SKILLNET_DATABASE_URL='postgres://skillnet@localhost/skillnet'
skillnet calibration migrate
```

Or with `skillnet.toml`:

```toml
[database]
url = "postgres://skillnet@localhost/skillnet"
```

Or through the Home Manager module:

```nix
programs.skillnet = {
  enable = true;
  package = inputs.skillnet.packages.${pkgs.system}.skillnet;
  database = {
    backend = "postgres";
    urlFile = config.age.secrets.skillnet-pg-url.path;
  };
};
```

`--database-url <URL>` overrides both environment and config for one command.
Plain URLs in `programs.skillnet.database.url` are written into the Nix store;
use `programs.skillnet.database.urlFile` with `sops-nix`, `agenix`, or another
secret-backed file for production credentials.

## Quick Start

Inspect the configured scopes and current divergence:

```sh
skillnet status
skillnet scope list
skillnet scope sources
```

Pull live skills into the mirror and then inspect or regenerate catalog output:

```sh
skillnet sync pull --scope global
skillnet skill list --scope global
skillnet catalog generate
```

Calibration commands are available under the dedicated command group:

```sh
skillnet calibration analyze --format table
skillnet calibration proposals --pending
```

## Development

Run the default test suite with:

```sh
cargo test --all-targets
```

Postgres parity tests run when `SKILLNET_TEST_PG_URL` points at a test database:

```sh
export SKILLNET_TEST_PG_URL='postgres://skillnet@localhost/skillnet_test'
cargo test-pg
```

## Configuration Model

`skillnet` keeps the mirror separate from live agent directories:

- `global/` stores the reconciled global skill mirror.
- `projects/<name>/` stores reconciled per-project mirrors.
- Live global sources typically come from `~/.agents/skills`, `~/.claude/skills`, and `~/.codex/skills`.
- Project scopes can add `.agents/skills`, `.claude/skills`, `.codex/skills`, root `skills`, plugin skill directories, and other configured paths.

Configuration lives in `skillnet.toml`. Catalog metadata lives in `skillnet.catalog.toml`.

## Command Surface

The current top-level commands are:

- `status`
- `completions`
- `sync`
- `skill`
- `scope`
- `project`
- `catalog`
- `calibration`

Generate shell completions with:

```sh
skillnet completions bash
skillnet completions zsh
skillnet completions fish
skillnet completions elvish
skillnet completions powershell
```
