-- Full, browsable index with every skill and its trigger description:
-  [`docs/agent-skills.md`](../../docs/agent-skills.md).
-- These are **slimmed** installs: only `SKILL.md` files and their Markdown
-  references are vendored; upstream build scripts, browser extensions, tests and
-  binaries are excluded to keep the repo lean.
-- To refresh/update from upstream:
-  `./scripts/install-agent-skills.sh && node scripts/gen-skills-index.js`.
-- Each pack directory retains its upstream `LICENSE` for attribution.
+- Full index: [`docs/agent-skills.md`](../../docs/agent-skills.md).
+- Why these packs: [`docs/agent-skill-packs.md`](../../docs/agent-skill-packs.md).
+- Slimmed install: `SKILL.md`, Markdown references, and each skill's `scripts/`.
+- Refresh: `./scripts/install-agent-skills.sh && node scripts/gen-skills-index.js`.
+- Pipeline: find-skills → spec (gstack **XOR** spec-kit **XOR** CE) → interrogate → implement (pstack **XOR** Superpowers) → review → ToB → agent-browser QA → ship → CE compound. Never run CE + gstack + Superpowers + pstack on the same task.
