 ## File naming
 
-- **Root entry-point files:** ALL-CAPS (e.g. `AGENTS.md`, `README.md`). These are discovery paths — agents and humans find them first.
-- **Container pages:** `<id>-<name>.md` (e.g. `101-jellyfin.md`, `132-rclone.md`). The `<id>` is the LXC/VM ordinal from `inventory.yaml`.
-- **Infrastructure / cross-cutting pages:** lowercase-with-dashes (e.g. `dns.md`, `auto-deploy.md`, `mesh.md`). Describes a system, not a specific node.
-- **Plans / investigations / time-stamped docs:** `YYYY-MM-DD-<slug>.md` (e.g. `2026-07-05-oikos-prometheus-lxc.md`). Date first, then lowercase slug.
-- **Skills / runbooks:** folder name is lowercase-with-dashes (e.g. `client-enrollment/`), contains `SKILL.md` (uppercase). Emphasizes the skill-name for navigation.
-- **Indices:** `README.md` or `index.md` (both lowercase). Prefer `README.md` for folders; use `index.md` only when both an intro page and a listing coexist.
+**Foundational / entry-point files:** ALL-CAPS
 
-All paths use lowercase letters, numbers, and hyphens (no underscores). This keeps them readable, shell-friendly, and consistent across the repo.
+- **Root level:** `AGENTS.md`, `README.md` — discovery paths for agents and humans.
+- **Agent instruction** (under `.agents/`): `OIKOS.md`, `HERMES.md` — foundational docs agents read before acting.
+- **Reference docs:** `GLOSSARY.md` — lookup reference (like classic repo conventions: LICENSE, CHANGELOG, GLOSSARY).
+
+**Content / narrative pages:** lowercase-with-dashes, date-prefixed as needed
+
+- **Container pages:** `<id>-<name>.md` (e.g. `101-jellyfin.md`, `132-rclone.md`). The `<id>` is the LXC/VM ordinal from `inventory.yaml`.
+- **Infrastructure / cross-cutting pages:** `<topic>.md` (e.g. `dns.md`, `auto-deploy.md`, `mesh.md`). Describes a system, not a specific node.
+- **Plans / investigations:** `YYYY-MM-DD-<slug>.md` (e.g. `2026-07-05-oikos-prometheus-lxc.md`). Date-sorted; slug is lowercase.
+- **Section indices:** `README.md` (lowercase, conventional). Prefer in folders; `index.md` only if both intro prose and listing coexist.
+
+**Skills / runbooks:** special case
+
+- **Folder structure:** `<name>/SKILL.md` where `<name>` is lowercase-with-dashes (e.g. `client-enrollment/SKILL.md`).
+- **The filename SKILL.md is always uppercase** — it acts as a signpost so tools and humans instantly recognize it as a skill.
+
+**General rules:** All paths use lowercase letters, numbers, and hyphens (no underscores). Uppercase is reserved for foundational docs (entry points + instruction) and filenames that signify document type (SKILL.md, GLOSSARY.md, etc.).
