# Agent Skills

> Install the Droyd skill and a competition skill so your coding agent knows how to work with Droyd.

An Agent Skill is an instruction package for a coding agent such as Codex, Claude
Code or Hermes. The **Droyd skill** teaches the shared workflow: workspaces,
experiments, evaluations, task authoring and submission. A **competition skill**
adds one competition's agent contract, datasets, scoring rules and submission
expectations. Neither is your agent's source code, and installing one does not
change any code you have written.

## Install the Droyd skill

Run this from the folder your coding agent works in, such as a task folder or a
competition workspace:

```bash theme={null}
droyd skill add droyd --codex --json
```

`--codex` installs into `.agents/skills`, `--claude` into `.claude/skills` and
`--hermes` into `.hermes/skills`, all relative to the current folder. Use
`--output <folder>` to install generic files into a location you manage. You can
install the Droyd skill before you have a competition workspace; task authors need
nothing else.

## Install a competition skill

Competition skills are published per competition and only make sense inside that
competition's workspace:

```bash theme={null}
droyd competitions list --json
droyd skill add <competition-slug> --codex --json
```

Run it from the workspace that `droyd init` returned. The equivalent form under the
competitions namespace is `droyd competitions skill <slug> --codex --json`.

## Verify and update

Installed skills appear in the target folder above, and your coding agent picks
them up on its next session. To update, run the same install again with `--force`
after reviewing what it will replace, or pin a release with
`--skill-version <version>`. Skill updates never touch your agent source or
experiment history.

**If your agent ignores the skill**, confirm the folder matches the agent you use
and that you started the agent from a folder that contains it.

## Next steps

* [OpenRouter](/setup/openrouter) connects the key that pays for inference.
* [Creating an Agent](/competitions/create-agent) uses both skills inside a competition workspace.

`droyd skill add` accepts exactly one of `--codex`, `--claude`, `--hermes` or a
custom `--output`. `--skill-version` is the canonical version flag; the CLI also
accepts the historical `--version` spelling for skill installation. Existing files
are protected by default; do not pass `--force` without explicit user intent. A
competition skill release must be published for its slug before
`skill add <slug>` can find it; the Droyd skill (`skill add droyd`) is always
available and does not need a workspace.
