Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00089 | $0.01090 |
| Opus 5 | $0.00044 | $0.00545 |
| Sonnet 5 | $0.00018 | $0.00218 |
| Haiku 4.5 | $0.00009 | $0.00109 |
Grade C, and why
og-generation scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

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/.
-
Restore the temp route from the skill asset:
mkdir -p src/app/og-card cp <skill-dir>/assets/og-card-page.tsx src/app/og-card/page.tsx -
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
Logocomponent). - Headline slogan has no trailing period.
- Subline: "Terminal-first Agentic Development Environment, built for AI builders."
- Agent row uses real
AgentIconicons; 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.pngat 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.
- Wordmark is capitalized "Termio" (matches the nav
-
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:
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-cardreturning 200 (and kill the server afterwards if you started it yourself).
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

og-generation is a skill published in the GitHub repository termio-sh/termio (395 stars, last pushed yesterday), licensed MIT. It adds 89 tokens to every session and 1,090 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Execute a workflow script that orchestrates multiple subagents deterministically. Use when the user explicitly requests a workflow, multi-agent orchestration, parallel or sequential agent pipelines, structured agent outputs, or a durable background workflow run.
