Clean Room

Overview

Produce clean behavioral specifications from authorized source analysis, then implement them in a separate clean destination code root. When no indexable source code exists and the user authorizes screenshots or images as evidence, produce clean behavioral specifications from contaminated visual observations instead. Keep contaminated source or visual evidence separate from clean planning, clean implementation, and verification.

This skill is not legal advice and does not create a legal safe harbor. Treat it as an engineering risk-reduction workflow for preserving a documented separation between source analysis, clean artifacts, and clean implementation code.

Required Gates

1. Create or validate preflight-goal.json before source discovery, decomposition, attended execution, or unattended execution.
2. Confirm authorization, source scope, destination scope, allowed actions, prohibited actions, and evidence handling rules.
3. Separate contaminated artifacts, clean artifacts, and clean implementation code into different workspaces, worktrees, or repositories. Prefer separate agent profiles or homes when platform support exists.
4. Keep contaminated chat history, raw source, raw diffs, source excerpts, comments, distinctive identifiers, and implementation-shaped pseudocode out of clean artifacts.
5. Produce structured artifacts for the audit trail: preflight goal, init config, clean run context, role session briefs, controller status, source index or visual index, task manifest, evidence ledger references, coverage ledger summaries, behavioral spec, handoff package, skeleton manifest, implementation plan, implementation report, QC report, open questions, incident records, and test plan.
6. Write clean implementation code only under CLEAN_ROOM_IMPLEMENTATION_ROOTS, never in source or contaminated artifact roots.
7. Treat allowed-tools and skill frontmatter as convenience, not as a security boundary. Enforce separation with workspace paths, profiles, role agents, hooks, schema validation, and artifact quarantine.
