Both spec docs and tasks 0001-0008 were mined into the personal wiki by
/consume; delete the scaffolding it consumed, leaving the now-empty spec/
and tasks/ directories in place.
Bring the feature's design record into git (it was authored across the
benchmark tasks but never committed). Cleaned to the repo's prose
standards on the way in: recast prose semicolons as separate sentences
and split multi-sentence lines to one sentence per line.
Add the content tier: a standalone flake that auto-discovers each skill
(a directory containing a SKILL.md, at any depth) and exposes it as an
individually addressable derivation built by lib.mkSkill. Directories
without a SKILL.md are descended through as cosmetic containers; once a
SKILL.md is found, that directory's subfolders are its assets, not
further skills. Skill names must be globally unique across the tree — a
collision is a hard eval-time error, not a warning.
A fixture-driven skill-build check under `nix flake check` exercises the
recursive walk, the builder, the SKILL.md-at-$out-root contract, the
eval-time name passthru, and the collision error. The repo ships no real
skill content yet, so packages.<system> is empty today.
