We built a capture layer for Aider, Cline, and Windsurf

Something that surprised me while building this week: "OpenAI-compatible" is a statement about the API shape, not about how code edits are expressed inside it.

Aider does not use tool calls. It sends edits as structured text blocks SEARCH/REPLACE delimiters inside the assistant message. The filename is on the line before the fence, not inside it. Cline and Continue use proper tool calls. A response from some backends carries both.

The adapter we shipped this week (`openai_chat.py` in the LineageLens proxy) handles all three patterns: tool-call edits, text-content edits (Aider SEARCH/REPLACE, unified diffs, fenced blocks), and mixed responses where both appear together. It covers Aider, Cline, Continue, Copilot CLI, Goose, Windsurf, and any OpenAI-compatible backend Azure, groq, fireworks, mistral, together.ai.

The hardest design decision was not the parsing. It was fail-open vs. fail-safe. If capture logic throws an error, do you surface it (fail-safe) or swallow it and pass through (fail-open)? We chose fail-open. A proxy that occasionally interrupts a developer's coding session gets uninstalled. Governance with a 60% retention rate is strictly worse than governance with 95% retention.

Building a BI layer for Product Hunt launches — what metrics would you like to see?

One recurring piece of feedback after launching PH Radar was that makers want more context, not just rankings.

I'm currently experimenting with a BI layer that analyzes Product Hunt activity beyond the daily leaderboard.

Current prototype dashboards include::

Launches by category
Votes by category
Hunter activity
Comment-to-vote ratios
Historical launch trends
