 ### Fixed
 - **`gstack-harness register openclaw`** (`lib/harness-register.ts`): a skill whose rendered `SKILL.md` is over 32,768 bytes (`OPENCLAW_INSTRUCTION_MAX`, with the OpenClaw source lines it comes from) is registered as a short entry with the same frontmatter whose body says to read the skill's full `SKILL.md` in a plain copy of every skill and follow it. In hybrid that copy is the router's `gstack/skills/`, where the router layout read the same file, now including the five task skills; under `--skills all` it is `.gstack-skills/`, a folder OpenClaw's skill scan skips. Because the copy holds every skill, `sections/` paths and sibling paths such as `../gstack-qa/` and autoplan's `../gstack-plan-eng-review/SKILL.md` resolve to full texts. That covers four of hybrid's five direct skills and 26 of 63 skills in `--skills all` today. OpenClaw treats only a registered skill folder's `SKILL.md` as an instruction file. The ledger records the copies, so refresh, mode switches, upgrades from a #3555 registration and uninstall handle them. Skill bodies are unchanged, and Hermes, dots and `generic` registrations are byte-identical.
-- docs/hosts.md and docs/OPENCLAW.md describe the entry and the limit.
+- docs/hosts.md and docs/OPENCLAW.md describe the entry and the limit, and docs/uninstall.md's manual OpenClaw removal command also removes `.gstack-skills/`.
 
 ### Tests
 - `test/harness-register.test.ts`: in hybrid and all, every `SKILL.md` OpenClaw would register is within the limit, each entry names a full `SKILL.md` that exists, has the same frontmatter, is outside OpenClaw's registered set and is in the ledger, every `../gstack-*` path in the copied texts resolves to a full text, re-registering over a #3555 registration converts it cleanly, and uninstall leaves nothing. Hermes's registration equals its render byte for byte. With `GSTACK_OPENCLAW_BIN` or `openclaw` on PATH, a real `openclaw skills list --json` and `skills info` show exactly `gstack` and the five task skills, each served from an entry within the limit.
