context-packet is a file-based context resolution library for AI agent DAG workflows. Three primitives, zero dependencies.

Core loop: Define a graph. Resolve upstream context. Do work. Submit a packet. Repeat.

Four interfaces:

MCP server — registered as context-packet in Claude Code. Agent gets tools to resolve/submit within a full session with all capabilities. The recommended approach for Claude Code workflows.
CLI — context-packet init|resolve|submit|read|status|hash|run — any process that can shell out
run command — context-packet run --agent "claude -p" --input "..." — executes entire DAG automatically with parallel node execution
TypeScript API — init(), resolve(), submit(), read(), status(), run()

Graph features:

depends_on — execution order edges (must complete before this node runs)
consumes — data edges (need the packet, no ordering constraint)
system — system prompts at graph level (all nodes) and node level (specialization)
config.maxTokens — per-node token budget for upstream context resolution
