Hoangsa
Description
HOANGSA is a context engineering system for Claude, Codex. It solves a fundamental problem: Claude's output quality degrades as the context window fills up.

The problem
An agent's output degrades as its context window fills. Ask for a feature and you get good code for the first file, plausible code for the fifth, and by the tenth it has forgotten a type it defined itself. Bigger context windows push the cliff back; they don't remove it.
The usual answers — "be more specific", "break it into steps" — are advice. HOANGSA is structure.
The idea
Split the work into tasks. Give each task its **own fresh context window** holding only what it needs: the files it may touch, the behaviour it must implement, the command that proves it worked. The orchestrator never writes code — it dispatches, checks, and assembles.
Everything else follows from that:
- A task needs a spec precise enough to execute from, so there is a design phase that produces one.
- A worker with no history needs its rules and context handed to it, so prompts are assembled by a CLI, not improvised by an agent.
- A claim of "done" from a fresh worker is unverifiable, so every deliverable has a command that must pass.
That last one is load-bearing. Prompt text is a sug
