Passalong

Hand finished work to another context.

Solve something non-trivial in one agent session. Open a session somewhere else — another repo, another machine, a teammate — and the agent there already knows the whole story: the problem, the decisions, the steps, how to verify, and what went wrong along the way.

Open your hub $npm i -g passalong
passalong.dev/g/ejdq3v8q · Verify
id ejdq3v8q published by @marta assumes Postgres 16, Node 22 #migrations

Backfill order totals without locking the table

Verification

  1. Run pnpm verify:totals — every row reconciles, exit 0.
  2. Check pg_stat_activity during the backfill: no lock waits over 50ms.

Gotchas

The obvious single UPDATE takes an ACCESS EXCLUSIVE lock and stalls checkout for ~40s. Batching by primary key in chunks of 5,000 avoids it.

How a transfer works

  1. Finish the work

    In an agent session, say “pass this along”, or run passalong share. It distills what you just did into a guide.

  2. Review and publish

    Trim the draft. You get a short id and a link. Hand it to a teammate with --to team/@them.

  3. Pick it up anywhere

    Run passalong pull <id> in the other context, or paste the link to an agent. Nothing to install on the receiving end.

If you write the guides

npm i -g passalong
passalong setup     # Claude Code skill + MCP
passalong login     # sync across machines

passalong board then tells you what is waiting on you, what you handed over that nobody has taken, what landed, and what someone says does not work.

If you pick them up

Testers, teammates, anyone the work gets handed to. Nothing to install. Open the invite link, pick a handle, and guides addressed to you land in your hub.

  • Every guide has a Verify view that leads with what to check and folds the implementation away.
  • Two answers when you have tried it: it works, or it does not — with a reason the author sees the same day.
  • The person who handed it over can see it landed, so nobody has to ask.

No lock-in

Guides are plain markdown with frontmatter. passalong export dumps everything. Deleting your account leaves you with all of your content.
