> clanker can create prompt templates. Ask it to build one for your workflow.
# Prompt Templates
Prompt templates are Markdown snippets that expand into full prompts. Type `/name` in the editor to invoke a template, where `name` is the filename without `.md`.
## Locations
Clanker loads prompt templates from:
- Global: `~/.clanker/agent/prompts/*.md`
- Project: `.clanker/prompts/*.md`
- Packages: `prompts/` directories or `clanker.prompts` entries in `package.json`
- Settings: `prompts` array with files or directories
- CLI: `--prompt-template <path>` (repeatable)
Disable discovery with `--no-prompt-templates`.
## Format
```markdown
---
description: Review staged git changes
---
Review the staged changes (`git diff --cached`). Focus on:
- Bugs and logic errors
- Security issues
- Error handling gaps
```
- The filename becomes the command name. `review.md` becomes `/review`.
- `description` is optional. If missing, the first non-empty line is used.
## Usage
Type `/` followed by the template name in the editor. Autocomplete shows available templates with descriptions.
```
/review # Expands review.md
/component Button # Expands with argument
/component Button "click handler" # Multiple arguments
```
## Arguments
Templates support positional arguments and simple slicing:
- `$1`, `$2`, ... positional args
- `$@` or `$ARGUMENTS` for all args joined
- `${@:N}` for args from the Nth position (1-indexed)
- `${@:N:L}` for `L` args starting at N
Example:
```markdown
---
description: Create a component
---
Create a React component named $1 with features: $@
```
Usage: `/component Button "onClick handler" "disabled support"`
## Loading Rules
- Template discovery in `prompts/` is non-recursive.
- If you want templates in subdirectories, add them explicitly via `prompts` settings or a package manifest.
