📝 Walkthrough

Walkthrough

A new GitHub Actions workflow (.github/workflows/pr-formatter.yml) is added. It triggers on pull_request opened events, calls the OpenAI Responses API twice—once to reformat the PR body into a structured markdown format and once to generate a semantic-release style title—then updates the PR via github.rest.pulls.update, appending the original description in a collapsible <details> block.

Changes

PR Auto-formatter Workflow

Layer / File(s)	Summary
Workflow trigger and permissions .github/workflows/pr-formatter.yml	Sets workflow name, pull_request opened trigger, and pull-requests: write permission.
Rewrite PR body via OpenAI .github/workflows/pr-formatter.yml	POSTs original PR body to OpenAI Responses API with a structured markdown instruction, parses output_text, and fails the workflow if empty.
Generate semantic-release PR title via OpenAI .github/workflows/pr-formatter.yml	POSTs the rewritten body to OpenAI to produce a semantic-release style title, parses output_text, fails if missing, and strips surrounding quotes.
Apply rewritten title and body to PR .github/workflows/pr-formatter.yml	Calls github.rest.pulls.update with the new title and body; body includes a collapsible <details> block with the original PR description.

Poem

🐇 Hop, hop, a PR arrives so bare,
OpenAI fluffs the body with care,
A semantic title springs from the air,
The original tucked in a <details> snare,
No messy PR shall ever despair! ✨

Inline comments:
In @.github/workflows/pr-formatter.yml:
- Around line 42-46: Update the default checklist text in the PR formatter
template so the fallback checklist reads naturally when the original body has no
items. In the workflow template that generates formatted PR descriptions,
replace the two default unchecked checklist entries with clearer, grammatically
correct wording, and keep the existing behavior of copying any original
checklist items exactly when they are present.
- Around line 34-35: Update the issue-linking text in the pr-formatter workflow
so it preserves the original keyword instead of always forcing “Closes”; in the
workflow/template logic around the issue placeholder, ensure the generated text
keeps values like “Related to” or “Refs” exactly as provided, and only uses
“Closes” when that was the intended original keyword.
