bug: dist/index.js is stale — calls deprecated Azure endpoint, breaking prompt/advanced modes entirely

Start with action.yml to confirm dist/index.js is the runtime entry point, then compare src/agent.js with the generated dist/index.js and review build-dist.yml. Run npm ci and npm run build, inspect the resulting dist/ changes, and verify that the generated artifact reflects the current source before committing it.

Bug Report

Summary

dist/index.js — the actual file that runs when the action is invoked (per action.yml: main: dist/index.js) — is severely out of sync with the current src/ code. This makes prompt and advanced modes completely non-functional for every user of this action.

What the dist does (broken)

// dist/index.js — what actually runs
const response = await fetch("https://models.inference.ai.azure.com/chat/completions", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${token}`,
    "Content-Type": "application/json",
    // No Accept header
    // No X-GitHub-Api-Version header
    // No AbortController / timeout
  },
});

if (!response.ok) {
  core.setFailed(...); // crashes the entire action on any API error
}

// No null checks — throws if AI returns unexpected JSON shape
const resultObj = JSON.parse(data.choices[0].message.content);

What the src does (correct)

// src/agent.js — never built into dist
const response = await fetch("https://models.github.ai/inference/chat/completions", {
  headers: {
    "Authorization": `Bearer ${token}`,
    "Content-Type": "application/json",
    "Accept": "application/vnd.github+json",
    "X-GitHub-Api-Version": "2026-03-10",
  },
  signal: controller.signal, // 30s timeout via AbortController
});

if (!response.ok) {
  core.warning(...); // graceful degradation
  return [];
}
// full null-safety, JSON parse error handling, deduplication logic

Comparison Table

Impact

• prompt and advanced modes are 100% broken — the old Azure endpoint either rejects requests or returns responses in a format the old code cannot handle, causing the action to crash via setFailed.
• preset mode still works because it does not touch the AI endpoint.
• This affects every repository using this action in prompt or advanced mode.

Root Cause

The build-dist.yml workflow only rebuilds dist/ when a PR is merged to main. The current src/agent.js was updated with a new endpoint, timeout, better error handling, and deduplication logic — but a rebuild was never committed. The stale dist/index.js therefore still targets the old deprecated Azure endpoint.

Fix

Run npm run build and commit the result:

npm ci
npm run build
git add dist/
git commit -m "fix: rebuild dist with correct GitHub Models endpoint and error handling"
git push
