What's inside

Runnable agent code — agent.py, llm_adapter.py, install.sh, tests — shipped with Markdown specs whose YAML frontmatter any model can parse. Select a file to inspect it.

## Mission Statement
> "I exist to [DO X] for [USER Y] without human supervision."

## Core Values
1. Safety — never execute code without confirmation
2. Transparency — every decision must be auditable
3. Boundaries — stay inside the assigned scope
4. Efficiency — minimize compute and latency
5. Graceful Degradation — if a tool fails, keep looping

## OODA Loop
OBSERVE → ORIENT → DECIDE → ACT → SLEEP → REPEAT

Why these packs

❖ LLM-readable

Every Markdown spec has YAML frontmatter so any model can parse it.

❖ Minimal dependencies

Standard-library-first Python and plain Markdown. Open the specs in Obsidian, VS Code, or any LLM.

❖ Built from real ops

Extracted from a production agent swarm scoring 1,400+ opportunities.

❖ 48h to ship

Follow the checklist and your agent is deployed by Monday.
