Feature hasn't been suggested before.

  • I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

Description

Problem

Custom command templates use $ARGUMENTS, $1, $2, etc. as placeholders for argument substitution. However, there is currently no way to escape these patterns when you need to include them as literal text in the template.

Use Case

I have a meta-command called opencode-new-command that helps create new OpenCode custom commands. In this command template, I want to instruct the LLM to use the placeholder syntax in the generated commands:

---
description: Create a new OpenCode command
---
Create a new custom command based on the user's requirements.
Use $1, $2, etc. for positional arguments and $ARGUMENTS for all arguments.

When I run /opencode-new-command my-new-cmd, the template gets processed and $1 is replaced with my-new-cmd, resulting in:

Use my-new-cmd, $2, etc. for positional arguments and  for all arguments.

This confuses the LLM since the instructions about placeholder syntax are mangled.

Current Behavior

  • $1, $2, etc. → replaced with positional arguments
  • $ARGUMENTS → replaced with all arguments
  • $$1, $$ARGUMENTS → results in $<value> (prepends $ to substituted value, doesn't escape)
  • \$1, \$ARGUMENTS → results in \<value> (prepends \ to substituted value, doesn't escape)

Expected Behavior

A way to escape $ so that literal $ARGUMENTS, $1, $2 text can be included in templates. Suggestions:

  • \$1 → literal $1
  • $$1 → literal $1 (double-dollar escape)
