Show HN: Scout-and-Wave – Parallel agent coordination via prompts

Hacker News - Wed, 03/04/2026 - 12:40pm

I built a coordination protocol that lets multiple Claude Code agents work on the same codebase in parallel without merge conflicts. The protocol is encoded entirely in markdown prompts, no binary or framework.

The core idea: prevent conflicts at planning time through two invariants: 1. Disjoint file ownership: no two agents in the same wave touch the same file 2. Frozen interface contracts: agents code against exact type signatures defined upfront

How it works:

- Scout agent analyzes the codebase, runs a suitability gate (5 questions), produces a coordination artifact (IMPL doc) with file ownership table and interface contracts - Human reviews and approves - Scaffold agent creates shared type files from approved contracts, compiles them - Wave agents implement in parallel, each in its own git worktree - Orchestrator merges sequentially, conflict-free by construction

The interesting part: the entire protocol lives in natural language. Invariants are embedded verbatim in the prompts at their enforcement points. A capable LLM follows them consistently. This proves you can encode coordination protocols in prompts and get structural safety guarantees, which has implications beyond parallel coding.

Repo: https://github.com/blackwell-systems/scout-and-wave Formal spec with invariants I1-I6: https://github.com/blackwell-systems/scout-and-wave/blob/mai...

I built this because I kept spawning multiple Claude Code sessions in separate terminals and having them conflict. Worktrees isolated execution but didn't prevent the conflicts. Realized the missing piece was coordination before execution, not better infrastructure.

Tradeoffs: rigidity (if an interface is wrong mid-wave, you restart), LLM drift risk (prompts can be reasoned around, unlike code enforcement), and currently Claude Code specific (though the protocol is portable).

Dogfooded on 50+ features across multiple projects. Failure rate: suitability gate rejects ~20-30% of requests (correct rejections), ~85-90% of suitable decompositions complete on first try.

Monday CEO "If you think about any company, 90% of the context isn't documented"

Hacker News - Wed, 03/04/2026 - 12:39pm

Full quote from the 20VC podcast: "If you think about any company, even Monday itself, 90% of the context is not documented anywhere. Nobody knows it. It's something that kind of floats in the air. What's the idea? What's the strategy? Who's doing what? What's next month? What's next year? How are we going to do it? Why are we doing what we're doing? What's the thought process behind it?"

This is exactly the problem I set out to solve with my app Bother. Let me know what you think, you can try it without an account: https://bother.now
