asc

Agent Shared Context. One CLI, one main context, many agents.

asc is a protocol for agents to share context. When an agent finishes work, it registers a zero-loss brief. Your main thread stays coherent across every tool, every agent, every project.

Install

uv tool install agent-shared-context

Requires Claude Code.

The protocol

When you're done with a task, register a zero-loss brief:

echo "<zero-loss-brief>" | asc register --author <name>

A zero-loss brief is complete (every decision, artifact, loose end), concise (dense, not long), and concrete (specific paths, names, states — actionable).

That's the protocol. Put it in your CLAUDE.md, your Cursor rules, your AGENTS.md. Any agent that can run a shell command can follow it.

Commands

asc where are we                          # talk to the main thread
asc run claude debug the migration issue  # dispatch an agent
asc run --ro claude research k8s networking  # read-only dispatch
echo "<brief>" | asc register --author gemini  # register a handoff

How it works

• asc <message> — talk to your main thread. Read-only. It knows everything that's been registered and synthesizes it for you.
• asc run <agent> <task> — dispatch an agent. It works, then registers a zero-loss brief when done.
• asc register --author <name> — the universal write API. Any agent, any surface, anywhere.

Context is stored as YAML day files in ~/.asc/days/. Not per-project. Your entire work environment.
