Sigils for SubAgent templates.

~T Sigil

The ~T sigil creates a PtcRunner.Template struct at compile time with extracted placeholders.

Examples

import PtcRunner.SubAgent.Sigils

~T"Hello {{name}}"
#=> %PtcRunner.Template{
#=>   template: "Hello {{name}}",
#=>   placeholders: [%{path: ["name"], type: :simple}]
#=> }

~T"User {{user.name}} has {{count}} items"
#=> %PtcRunner.Template{
#=>   template: "User {{user.name}} has {{count}} items",
#=>   placeholders: [
#=>     %{path: ["user", "name"], type: :simple},
#=>     %{path: ["count"], type: :simple}
#=>   ]
#=> }

The sigil also supports heredoc syntax:

~T"""
Hello {{name}},

You have {{items.count}} items.
"""

Use PtcRunner.SubAgent.PromptExpander.expand/2 to expand the template with values.

Note on Elixir's Built-in ~T Sigil

Elixir has a built-in ~T sigil for Time structs (e.g., ~T[00:00:00]). When you import this module, our ~T sigil shadows the built-in one.

This is safe in practice because:

• The built-in ~T uses square brackets: ~T[00:00:00]
• Our ~T uses double quotes: ~T"Hello {{name}}"
• Files using Time literals typically don't import this module

If you need both in the same file, you can use Time.new!/3 instead of the Time sigil, or explicitly qualify the Time sigil with import Kernel, only: [sigil_T: 2].
