Foundation step for brain v2 — establish canonical structure for skills
and rules. Adds two new meta-plugins to brain stack:
- skill-creator@claude-plugins-official (Anthropic verified)
- claude-code-setup@claude-plugins-official (Anthropic verified)
Phase 0 deliverables:
- preliminary.md: frontmatter conventions diff (Anthropic vs Obra),
brain v1 inventory (0 custom skills, 17 inherited from 4 plugins),
initial canonical decision before install
- final.md: post-install findings, divergences from preliminary,
recommender output (manually applied on brain repo only — Liderra
scope excluded per user instruction), audit of 17 inherited skills
Key findings:
- Anthropic skill-creator and Obra writing-skills are DIFFERENT
philosophies (scientific vs disciplinarian), not just complementary.
Decision: structure from Anthropic + testing from Obra, scoped by
skill type
- `tools:` frontmatter field is OPTIONAL even in Anthropic canonical
- skill-creator advocates "pushy" descriptions against undertriggering
(opposite to Obra's "Use when only" rule)
- Anthropic explicit anti-pattern: «If you find yourself writing ALWAYS
or NEVER in all caps — yellow flag, reframe and explain reasoning»
- ui-ux-pro-max uses LEGACY skill.json format (others use SKILL.md) —
brain v2 must support both schemas
Recommender external validation added 2 new candidates to shortlist:
plugin-dev (Anthropic) and hookify (Anthropic) — both high-ROI for
brain as plugin distributor.
Install method: Path 2 (manual git clone) — Claude CLI not installed
on machine, VSCode extension doesn't support /plugin install.
Settings.json and installed_plugins.json manually updated outside repo
(in ~/.claude/).
