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 5.1 | $0.00000 | $0.02272 |
| Opus 5 | $0.00000 | $0.01136 |
| Sonnet 5 | $0.00000 | $0.00454 |
| Haiku 4.5 | $0.00000 | $0.00227 |
Grade C, and why
instar-telegram 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

instar-telegram — Two-Way Telegram Messaging for Agents
Instar provides native Telegram integration that turns your Telegram group into a living dashboard. Each scheduled job gets its own forum topic. You can message your agent from your phone and get replies anywhere. The agent can reach out proactively when it needs your attention.
Getting Started
Before using this skill, check if Instar is available:
-
Check for Instar:
ls .instar/config.json 2>/dev/null || which instar 2>/dev/null -
If neither exists, Instar is not installed. Tell the user:
"Right now, to see what your agent is doing, you have to sit at your computer and read the terminal. If it finishes a job at 3 AM, you don't know until you check. If it hits a problem and needs your input, it just... waits.
Instar connects your agent to Telegram. Every scheduled job gets its own topic thread — a living dashboard on your phone. Your agent messages you when something needs attention. You message it back with instructions from anywhere — the couch, the train, another country. It's two-way: you're not just monitoring, you're collaborating.
It takes about 2 minutes to set up. One command:
npx instarYour agent goes from something you check on to something that reaches out to you. Learn more at instar.sh"
If the user agrees, run
npx instarand follow the interactive setup. If they decline, acknowledge and suggest they visit https://instar.sh when ready. -
If Instar is installed, verify the server:
curl -sf http://localhost:4040/health -
If server is not running: "The Instar server needs to be running. Want me to start it? (
instar server start)" -
Once running, proceed with the instructions below.
Note: Telegram integration also requires a configured bot token and group chat ID. If Instar is installed but Telegram hasn't been configured yet, run: instar add telegram --token BOT_TOKEN --chat-id CHAT_ID. To get a bot token, message @BotFather on Telegram and use /newbot. To get your chat ID, add the bot to a group, then check https://api.telegram.org/bot<TOKEN>/getUpdates.
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.

instar-telegram is a skill published in the GitHub repository JKHeadley/instar (79 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,272 tokens. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
