trace.

— short description

a cli agent that plans, acts, and shows its receipts — so you can watch autonomy happen, not just trust it. r3f + rust wasm.

context.

most agents are a chat window and a black box. trace inverts the premise: the plan is a first-class object, visible to the user, editable before it runs. every action leaves a receipt.

01a plan, before any tool call. editable, annotatable, revocable.
02the act — agent runs with a visible stack, one tool call at a time.
03the receipt — a diff of world state the agent made, kept in git.
— approach

plan · act · receipt.

three phases, three surfaces. the plan surface is a tree. the act surface is a log. the receipt surface is a diff. every run is replayable from the cli or the web.

"finally, an agent that doesn't ask me to trust it — it asks me to read."
— alpha tester, week 02
— outcome

what shipped in the alpha.

the cli, the web replay, the rust runtime, and a set of built-in tools. the wasm runtime is small enough to run in a worker.

a production-quality demonstration that attention can be settled in public at the unit of the second. still my favorite project of 2024.
