Good fit. I read the repo and your Search Console export.

Three systems fit: organic growth, content, and a Monday note on what to try next.

Turn on organic growth first? The first audit takes about four minutes.

It lives in your agent and your repo.Nothing ships without you.

Your coding agent already knows how. Tin is an MCP server. Ask how it could help, and it reads the repo and answers.

›How could Tin help me grow virvid.app?

This is a good fit. I read the repo, your Search Console export and the skills you already keep in .claude/skills.

Three systems I would set up:

Organic growth
you rank on page two for “video API for agents”. Weekly audits, answer pages, and the canonical fixes.
Content
a launch post each time you ship, drafted from the changelog in your voice.
What to work on next
a Monday note that reads Stripe and Search Console and says what to try.

Plain files, with git history. Your voice, research and every draft live in the repo, where your agent can read them.

Files

    • # Scanning a project
      Read what exists before proposing anything.
      1. Sitemap, robots, canonical tags
      2. What the site says it is for
      3. Where it nearly ranks
    • # Answer pages
      One page for one buyer question, in your words.
      Answer in the first two lines, then show the work.
    • # Technical SEO
      Crawlable, canonical, fast enough. In that order.
      Fix what blocks the crawler before writing anything new.
    • # Virvid memory
      Product: a video API for agents. Live since 2026-03.
      Buyers ask: which video API works with an agent framework.
      ## Sources
      6 runs, latest 2026-09-15.
    • # Positioning
      Virvid is a video API for agents, not for editors.
      Against: APIs that assume a human presses render.
    • # Writing style
      - Short sentences. One idea in each.
      - We for the team, you for the reader. No one else.
      - Say the number, the file, the date. Never “seamless”.
      - End on what happens next, not on a summary.

      title: Video API for agents: what to check before you build
      status: draft, waits in Decisions
      ---
      Most guides start with the SDK. Start with the failure modes.
    • # 2026-Q4
      Three answer pages, one launch post, one case study.
      Ships weekly. Reviewed Mondays, in Decisions.
    • # Changelog: scheduled runs
      Runs start on their own now, on the schedule you set.
      What you do differently: nothing.

    • # Scan: virvid.app
      42 pages read. 3 issues, 2 questions for you.
      No canonical on /docs. One title used on 6 pages.
    • # Week of 2026-09-15
      Moved: audit done, one PR merged.
      Needs you: nothing.
      Smallest next step: publish the answer page.
    • # Signup QA, 2026-09-15
      Ran the signup as a new account. 4 steps, 1 dead end.
      The verification link expired before the email arrived.

  • # AGENTS.md
    This project runs on Tin. Before proposing work:
    1. Read company-wiki/INDEX.md.
    2. Check reports/ for the latest audit.
    3. Write in the voice in skills/writing-style/SKILL.md.
  • # Virvid
    A video API for agents.
    This folder is the marketing project Tin keeps for it: knowledge, drafts, reports, all as files with history.

You approve what ships. Drafts arrive as a pull request or a one-click publish. Nothing goes out on its own.
