thc j: today's journal. A paragraph is a note; [ ] makes a task; due:tue, !high and #lisbon are read as you type.
01 why
01 · writing
Plain text, with structure
A page is a buffer you just type into. Markdown markers make tasks, lists and headings; the marker is the truth. No modes, no forms. The editor runs on caretline.
02 · agents
Agents as colleagues
--json everywhere, stable exit codes, idempotent keys, guarded writes. Every agent change is signed and waits in a review lane.
03 · the record
Nothing is ever overwritten
One JSON line per change, per device. Undo anything, see any note's history, ask what a page looked like last Tuesday.
04 · yours
Yours, locally
No account and no server. A vault is a folder: sync it with anything. Conflicts keep both versions, and you choose.
02 the loop
03 agents
You steer them. They steer you. The log keeps score.
Claude Code, Codex and your own scripts use the same thc you do. Every write carries its author, ◆ claude, and waits in the review lane until you press a or u. Only a person can accept.
Guarded writes.--expect status=todo claims a task once; the second agent gets exit 4.
A team on one board.thc team up starts one agent per role; thc next hands out work in your order.
Taught once.thc setup claude --user installs a skill generated from the binary.

The review lane: what an agent changed, waiting for a or u.for review
04 contexts
See only what you're cleared here for.
A context lays a saved view over everything you see: only #work while you're at work. The header names it the whole time it's on, so nothing is withheld without you knowing. It stays on this device and is never synced. C in the app, or thc context work.
One line to install, then thc j and start typing. The first ten minutes walk you through the rest.
