What problem does it solve? Agents working in the SourceA ecosystem can drift out of their assigned roles, write across lanes, or claim work is done without proof. This Skill establishes the foundational operating rules every agent must load at session start so that decisions, disk state, and validation receipts stay consistent. ## Core Features & Use Cases - Session gate enforcement: Runs a mandatory session gate script and reads receipt files before any work begins, ensuring each agent operates within its role authority. - Layer stack and role discipline: Defines the L0-L3 layer model (founder, machine pipeline, routing roles, workers, portfolio repos) with explicit execution authority per role. - Defense in depth (SASCIP): Eight fail-closed layers including stranger quarantine, cross-lane edit guards, and founder verb gating for disk writes. - Use Case: A worker agent starts a session, runs the session gate, checks live surfaces, executes one bounded change in its lane, and verifies with a validator script before claiming completion. ## Quick Start Load this foundational skill at the start of every session and run the session gate script for your role before making any changes.
