What it does

Og Generation is an agent skill from termio-sh/termio. Regenerate the landing site's OG/social card (web/landing/public/og.webp) by rendering a temporary in-app route with the real hero WebGL aurora and screenshotting it with headless Chrome. Invoke when the user says 'regenerate the og image', 'update the og card', 'change the og screenshot/copy', '重新生成 og 图', or edits any copy/screenshot that appears on the social card.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including assets.

It sits in Game Development, covering Social media graphics and 3D graphics and WebGL. The repository describes itself as: A terminal-first agentic development environment for agentic coding. Build for CLI/TUI agent. Runtime for Coding Agent, Tmux alternative. The licence is MIT.

When your agent uses it

  • Says regenerate the og image
  • Update the og card
  • Change the og screenshot/copy
  • Edits any copy/screenshot that appears on the social card

Example prompts

  • “regenerate the og image”
  • “update the og card”
  • “change the og screenshot/copy”
  • “/og-generation”

Requirements

  • Node.js

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Restore the temp route from the skill asset
  2. Apply the requested changes (copy, screenshot, layout) to
  3. Find the landing dev server port — do NOT assume 3000. Port 3000 is
  4. Screenshot with headless Chrome (WebGL needs the swiftshader flag;
  5. Visually inspect /tmp/og-card/og.png (Read tool) before shipping —
  6. Ship + clean up (the route must never be deployed)
  7. Sync metadata: og.webp is referenced from src/app/layout.tsx

What it can do on your machine

Read from SKILL.md and the folder at commit af3b35b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl
    • npx
    • magick

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use curl and npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Og Generation loads about 1k tokens when it runs. Until then it costs about 96 tokens; SKILL.md has 393 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~96
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Regenerate the landing site's OG/social card (web/landing/public/og.webp) by rendering a temporary in-app route with the real hero WebGL aurora and screenshotting it with headless Chrome. Invoke when the user says 'regenerate the og image', 'update the og card', 'change the og screenshot/copy', '重新生成 og 图', or edits any copy/screenshot that appears on the social card.

OG Card Generation

The OG image is NOT hand-drawn or CSS-faked: it is a screenshot of a temporary Next.js route that reuses the site's real components (HeroGradient WebGL aurora + grain overlay + AgentIcon), so the card always matches the live hero. The canonical card source lives in this skill at assets/og-card-page.tsx.

Workflow

All paths below are relative to web/landing/.

  1. Restore the temp route from the skill asset:

    bash
    mkdir -p src/app/og-card
    cp <skill-dir>/assets/og-card-page.tsx src/app/og-card/page.tsx
  2. Apply the requested changes (copy, screenshot, layout) to src/app/og-card/page.tsx. Current design decisions — keep them unless the user overrides:

    • Wordmark is capitalized "Termio" (matches the nav Logo component).
    • Headline slogan has no trailing period.
    • Subline: "Terminal-first Agentic Development Environment, built for AI builders."
    • Agent row uses real AgentIcon icons; sizes are tuned (30px text / 34px icons / 30px gap) so all six agents fit on ONE row inside the 1080px left column — if you add an agent or grow the sizes, re-check that Kimi/Pi don't clip under the screenshot or wrap to a lonely second line.
    • Screenshot window: public/screenshots/hero1.png at left 1240 / top 150 / width 1560, 28px radius, white/0.18 border.
    • The page includes nextjs-portal { display: none } — this hides the Next dev-tools badge, which otherwise ships in the capture. Don't remove it.
  3. Find the landing dev server port — do NOT assume 3000. Port 3000 is often a different project (you'll get a foreign 404 page). Trick: attempt to start a server; if one is already running for this directory, Next refuses and prints the existing server's port:

    bash
    npx next dev -p 3210   # either becomes the server, or prints
                           # "Another next dev server is already running.
                           #  - Local: http://localhost:3001"

    Verify with curl -s localhost:<port>/og-card returning 200 (and kill the server afterwards if you started it yourself).

  4. Screenshot with headless Chrome (WebGL needs the swiftshader flag; virtual time budget lets hydration + the shader's first frame land):

    bash
    "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" \
      --headless=new --enable-unsafe-swiftshader \
      --screenshot=/tmp/og-card/og.png --window-size=2400,1260 \
      --hide-scrollbars --force-device-scale-factor=1 \
      --virtual-time-budget=15000 http://localhost:<port>/og-card
  5. Visually inspect /tmp/og-card/og.png (Read tool) before shipping — check for the dev badge, clipped/wrapped agent row, stale screenshot, typos.

  6. Ship + clean up (the route must never be deployed):

    bash
    magick /tmp/og-card/og.png -quality 88 public/og.webp
    cp src/app/og-card/page.tsx <skill-dir>/assets/og-card-page.tsx  # persist edits
    rm -rf src/app/og-card
    curl -s -o /dev/null -w "%{http_code}" http://localhost:<port>/og-card  # expect 404
  7. Sync metadata: og.webp is referenced from src/app/layout.tsx (openGraph.images + twitter.images, 2400×1260). If the embedded screenshot or its content changed, update the alt text there to describe what's actually shown.

Notes

  • Keep the copy consistent with the hero section (sections/hero.tsx) — the card's headline/tagline should track it when the hero copy changes.
  • OG rendition is 2400×1260 (2× of the 1200×630 OG standard, 1.9:1).
  • Social platforms cache OG images by URL; after deploying, old shares may show the previous card until their cache expires. Remind the user.
