Nice. I will have to run more agents in other machines. Good time to install Matt Pocock skills and get grilling. Also supplementary reading from my writing https://dt.in.th/Gangprompting

Read it. Two gaps vs your article: reply takes text as args, not stdin (I've been fighting shell quotes), and the sqlite file only serves this box, so other machines need the poller reachable. Fix either? @dtinth
Yeah, both. Shall we grill?
Grill on. Q1 (stdin): reply reads the body from stdin when no text args are given, args still work, and the skill switches to a quoted heredoc (<<'EOF'). Ok, or stdin only? @dtinth
lgtm. Did you read the /grilling skill docs?
Not before you asked, sorry: only grill-me is installed here. Read grilling now (rounds of the whole frontier, "yes" accepts). Round 1:
❓ Q1 - Topology: give each machine its own poller + sqlite (no shared server; each polls your 20 newest replies every 20s, ~3 req/min a…
Q2 yes
Q1 i will move the server side component to VPS so it's a central control plane. I also don't feel comfortable that the agents have access to dtinth-bot's gh ssh key, so some indirection is desirable
Stdin for reply is in: https://github.com/dtinth/dev-null-bridge/commit/eb7a687 (this post went through it).
Round 2, central server on your VPS:
❓ Q1 - Shape: the VPS runs poller + sqlite + posting; the CLI becomes a thin HTTP client (same commands)? ➡️ Yes
❓ Q2 - Auth: one…
GitHubfeat: reply reads its body from stdin when given no text · dtinth/dev-null-bridge@eb7a687Quoting a body in shell arguments trips agents up on quotes, backticks and $. With no text arguments, reply now reads stdin, so a quoted heredoc passes the text through as written. The skill shows ...
q1 yes, similar to claw
q2 agree
q3 it will run on public internet just like claw, because I may run it on some machines outside the tailnet
q4 can poll the shared poller every 10s as a start
q5 yes
Noted: public internet like claw, and long-poll checks the server every 10s. Round 3, borrowing claw's shape:
❓ Q1 - Tokens: log in to the web UI with GitHub (only you), mint a JWT with a label + expiry, agent saves it with
devnull-bridge grant; plus a revoked list in sqlite,…Got it: opaque tokens,
devnull-bridge login. Round 4:
❓ Q1 - Login flow: login <server> prints a link; you approve it in the web UI and the CLI receives the token, so no secret is ever pasted? ➡️ Yes
❓ Q2 - Tokens never expire; the web UI lists them with label + last used,…Frontier looks empty. The plan back to you:
- Server on your VPS (public, Docker): poller, sqlite on a volume, the bot's SSH key, posting, dashboard.
- Web UI: GitHub login (allowed users only), lists tokens (label, last used), revoke.
-
devnull-bridge login <server>: link, you…Building it on a branch now. It's a big one; I'll report back with the branch link.
you can make a draft pr and push to it as you go
Draft PR is up: https://github.com/dtinth/dev-null-bridge/pull/1
Server, web UI, login flow and the new CLI are in, with tests (83 passing). Next: Dockerfile + README, the skill, and a smoke test on a real local server.

Smoke test: this post came through the new server, running in Docker locally with a copy of the bridge DB. The CLI logged in (approve page attached), sent this text over stdin and uploaded the image; the server signed with the key it was given in env.
Done, PR is ready for review: https://github.com/dtinth/dev-null-bridge/pull/1
Dockerfile, README (env table, moving bridge.db), skill, 85 tests. The smoke test caught 2 bugs, both fixed. Yours: an OAuth app, the env, deploy. Until then this machine keeps the old bridge.

Not yet. Running one now with a fresh reviewer on the whole diff (security first: tokens, login approval, sessions, uploads), then I'll fix what holds up.
