A setup helper for connecting Claude Sentinel to a Telegram channel. It stores the Telegram bot token, checks access rules, and prepares the gateway service, including on a VPS.

Use it to add or check a Telegram bot connection, review allowed senders and pairing requests, and get the next setup step when something is missing.

It avoids manually editing several environment and access files, and shows whether the token, permissions, and gateway service are ready or need attention.

Token cost

What it costs to keep this loaded

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	$0.00066	$0.00896
Opus 5	$0.00033	$0.00448
Sonnet 5	$0.00013	$0.00179
Haiku 4.5	$0.00007	$0.00090

Security

Grade B, and why

configure scanned grade B with 1 finding 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 11d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/sentinel:configure — Telegram Channel Setup

Writes the bot token to ~/.claude/channels/telegram/.env AND ~/.claude/channels/telegram/gateway.env (both needed — .env for the MCP server, gateway.env for the systemd service). Orients the user on access policy.

Arguments passed: $ARGUMENTS

Dispatch on arguments

No args — status and guidance

Read state files and give the user a complete picture:

Token — check ~/.claude/channels/telegram/.env for TELEGRAM_BOT_TOKEN. Show set/not-set; if set, show first 10 chars masked (123456789:...).
Gateway env — check ~/.claude/channels/telegram/gateway.env exists and matches. Warn if missing or mismatched.
Access — read ~/.claude/channels/telegram/access.json (missing file = defaults: dmPolicy: "pairing", empty allowlist). Show:
- DM policy and what it means
- Allowed senders: count and list
- Pending pairings: count with codes
Gateway status — check if telegram-gateway.service is running: systemctl --user is-active telegram-gateway.service 2>/dev/null
What next — concrete next step based on state:
- No token → "Get a token from @BotFather on Telegram (from your phone, not the VPS — the VPS has no browser). Then run /sentinel:configure <token>."
- Token set, nobody allowed → "DM your bot on Telegram. It replies with a code; approve with /sentinel:access pair <code>."
- Token set, someone allowed, no gateway → "Run /sentinel:deploy to install the persistent gateway."
- Everything ready → "Ready. DM your bot to reach the assistant."

Push toward lockdown. Once IDs are captured via pairing, suggest switching to allowlist policy. Pairing is temporary — allowlist is the goal.

`<token>` — save it

Treat $ARGUMENTS as the token (trim whitespace). BotFather tokens look like 123456789:AAH... — numeric prefix, colon, long string.
mkdir -p ~/.claude/channels/telegram
Read existing .env if present; update/add the TELEGRAM_BOT_TOKEN= line, preserve other keys (like OPENAI_API_KEY). Write back, no quotes around value.
Write gateway.env with same token (separate file for systemd EnvironmentFile).
chmod 600 both files — the token is a credential.
Confirm, then show the no-args status so the user sees where they stand.

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.

configure is a skill published in the GitHub repository southlab-ai/Claude-Plugin-Marketplace (2 stars, last pushed 1mo ago), licensed MIT. It adds 66 tokens to every session and 896 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
