What happened?
Pi's argument parsing for prompt-templates seems to be broken. Pi docs: https://pi.dev/docs/latest/prompt-templates#arguments I want to create a custom prompt (say arg-test), and use it like this:
/arg-test short-label
Verbose description...
Expected:
$1: "short-label"${@:2}: Verbose description ...
What I get:
$1: "short-label"${@:2}: description ....
Info:
- Pi: 0.74.0
- Node: v26.1.0
- OS: macos Tahoe
Steps to reproduce
Prompt Template
File: .pi/prompts/arg-test.md:
---
description: test pi's prompt template argument substitution
---
Parse the name-value pairs below, and return the names and values back.
- arg1: $1
- rest: ${@:2}Test 1 (passes)
Prompt in CLI:
/arg-test label-1 Here is some description #1.
Wire-request (JSON) snippet:
{
"role": "user",
"content": [
{
"type": "text",
"text": "Parse the name-value pairs below, and return the names and values back.\n\n- arg1: label-1\n- rest: Here is some description #1."
}
]
}CLI shows input:
Parse the name-value pairs below, and return the names and values back.
- arg1: label-1
- rest: Here is some description #1.
CLI shows output:
Here are the parsed name-value pairs:
┌──────┬──────────────────────────────┐
│ Name │ Value │
├──────┼──────────────────────────────┤
│ arg1 │ label-1 │
├──────┼──────────────────────────────┤
│ rest │ Here is some description #1. │
└──────┴──────────────────────────────┘
Test 2 (fails)
Prompt in CLI:
/arg-test label-2
Here is some description #2.
CLI shows input:
Parse the name-value pairs below, and return the names and values back.
- arg1: label-2
Here
- rest: is some description #2.
Wire-request (JSON) snippet:
{
"role": "user",
"content": [
{
"type": "text",
"text": "Parse the name-value pairs below, and return the names and values back.\n\n- arg1: label-2\n\nHere\n- rest: is some description #2."
}
]
}CLI shows output:
Here are the parsed name-value pairs:
┌──────┬─────────────────────────┐
│ Name │ Value │
├──────┼─────────────────────────┤
│ arg1 │ label-2 │
├──────┼─────────────────────────┤
│ rest │ is some description #2. │
└──────┴─────────────────────────┘
Expected behavior
In Test 2, I expect the CLI to convert my prompt to the input:
Parse the name-value pairs below, and return the names and values back.
- arg1: label-2
- rest: Here is some description #2.
