Start Technologies is a monorepo, meaning one repository containing the source for several related products, including StartOS, StartWRT, StartTunnel, developer tools, and shared libraries. Its products support personal servers, routers, VPN or forwarding, service packaging, registries, and related self-hosting tasks, with shared Rust and Angular code. Catalogue add-ons support development across this product repository.
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 | $0.00129 | $0.02997 |
| Opus 5 | $0.00064 | $0.01499 |
| Sonnet 5 | $0.00026 | $0.00599 |
| Haiku 4.5 | $0.00013 | $0.00300 |
Grade A, and why
start9-frontend scanned grade A with 0 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Start9 Frontend — Angular + Taiga UI house style
Canonical for every Start9 web UI, distilled from the fleet's codebases and from the refactor and review history that shaped them. Follow it and new code matches the fleet; deviate and expect it to be rewritten in review.
Authority order: Taiga UI docs > this skill > neighboring code. The codebases are
mid-migration — "matches existing repo patterns" is not a quality bar; old code is often
exactly what this skill exists to eliminate. Never guess a Taiga API: verify against the
taiga-ui-mcp MCP server or https://taiga-ui.dev/llms-full.txt.

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.

start9-frontend is a skill published in the GitHub repository Start9Labs/start-technologies (1,981 stars, last pushed today), licensed MIT. It adds 129 tokens to every session and 2,997 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
