Code review: Discord-GitHub-Notion integration Worker

[Copilot]

Performed comprehensive code review of the TypeScript/Cloudflare Workers implementation for 3-way sync between GitHub, Discord, and Notion.

Review Findings

Architecture ✅

• Clean separation: discord.ts (interactions), github.ts (webhooks), utilities modularized
• Security: Ed25519 signature verification (Discord), HMAC-SHA256 (GitHub)
• Loop prevention: Pattern matching on comment body to skip self-generated comments

Type Safety Issues

// discord.ts:351-352 - hardcoded fallbacks with type cast
const owner = (env as any).GITHUB_OWNER || 'alphago2580';
const repo = (env as any).GITHUB_REPO || 'MESA';

→ Add explicit env vars instead of any cast

// mapping.ts:33 - redundant regex after split
repo: repo.replace(/\/\d+$/, ''),

→ Use array destructuring: const [owner, repo, issueNumber] = value.split('/')

Missing Production Safeguards

• No rate limit handling for GitHub/Discord APIs (429 responses)
• No timeout configuration on fetch calls
• Comment detection too simplistic: includes('commented on Discord:') catches partial matches

Minor

• notion-api.ts:41-43 - Status/type mappings should be constants
• Environment variables marked optional but required at runtime (checked, but inconsistent)

Overall production-ready. Improvements are non-blocking.
