Intent

ok, push to repo learn-firstmate as reference

"This" is a just-finished research report (Chinese, 2026-09-29) on which AI-related tool website to build first as a new product. It covers a check of the 2026 "small tool makes money" pattern against verified revenue data, selection criteria and scoring, a long list of about 27 candidates with elimination reasons, a comparison of 6 shortlisted directions, and a deep dive on the recommended direction (an AI sheet-music transcription website: users upload a song or recording and get a playable lead sheet and easy piano arrangements), including keywords, competitors, MVP scope, tech route, unit economics, acquisition plan, risks, and next steps. The repo already holds an earlier report as reference material at references/agent-skills-evaluation-2026-09-28.md, linked from README's reference-material section.

What Changed

• Adds references/ai-tool-site-research-2026-09-29.md, a Chinese research snapshot dated 2026-09-29 on which AI tool website to build first. It checks the 2026 "small tool makes money" pattern against verified revenue data, sets selection criteria and scoring, lists about 27 eliminated candidates with reasons, and compares 6 shortlisted directions. It then goes deep on the recommended direction, an AI sheet-music transcription site: keywords, competitors, MVP scope, tech route, unit economics, acquisition, risks, and next steps. Appendices hold the sources, Google Trends data, autocomplete samples, competitor traffic, license checks, and a command log.
• Links the new report from the reference-material section of README.md, next to the existing agent-skills evaluation report.

Risk Assessment

✅ Low: The change adds one reference document and one README link that matches the existing reference-material pattern. The fix from round 1 correctly replaces the private backlog clause with a neutral "the direction decision is still pending", as the user instructed. No private paths or captain-private data appear in the document.

Testing

This change only adds a Markdown reference report and a README link, so there is no product to run live. The baseline docs check passed again and confirms the new link resolves. The diff contains only the expected two files. Targeted greps found no private paths or backlog references. The requested fix, reducing section 8 step 1 to saying the decision is pending, is present. No visual artifact was captured: this is plain Markdown in a docs repo, and rendering it through GitHub's API would publish unreleased content to an external service.

• ℹ️ references/ai-tool-site-research-2026-09-29.md:413 - Section 8 step 1 says the pending decision "已登记为待办队列（backlog）里的一条工单，等待决定". That backlog is the captain's own private FirstMate state (outside this repo), so readers of the reference copy cannot see it and the statement will go stale. The earlier reference (agent-skills-evaluation-2026-09-28.md) notes that captain-specific content was removed when it was imported. Consider dropping that sentence or saying the decision is pending, for consistency. No private path or data is exposed.

🔧 Fix applied.
✅ Re-checked - no issues remain.
