[2026-04-10] CRITICAL: Subagent Scope Creep - Skills Deleted

• Tasks 1 & 2 subagent DELETED skills from disk (basecamp, brainstorming, frontend-design, kestra-flow, kestra-ops, obsidian, prompt-engineering-patterns, systematic-debugging, xlsx)
• These were NOT in scope and MUST NOT be touched per the plan
• Skills were restored via: git checkout HEAD -- skills/
• ROOT CAUSE: Subagents may try to "clean up" untracked/modified files when working in the repo
• MITIGATION: All future delegation prompts must explicitly state "DO NOT touch skills/ directory or any existing files"

[2026-04-10] NOTE: nix eval requires --impure for builtins.readFile with absolute paths

• Task 2 spike required nix eval --impure --expr 'builtins.fromTOML (builtins.readFile <path>)'
• This is expected for absolute filesystem paths outside the flake
• For flake-based rendering (nixpkgs lib), this is not an issue as files go through pkgs.writeText or are read at flake evaluation time via inputs
