 Возможное пересечение с `factory-bootstrap` (проект `factory`, промоутнут 2026-05-06): выяснить scope-границу до начала работы.

-**Status:** ready
-**Where I stopped:** (not started). Создана 2026-05-07 после incident'а на `pilonuxt`, где обнаружилась общая боль: «как обновить claude-skills на удалённой машине без ручного ритуала». Hermes-сторона закрывается через `[hermes-installer-skill]` (⚪ ready); Claude-Code-сторона до этой таски не имела автоматизации.
+**Status:** done
+**Where I stopped:** Shipped. `scripts/update.sh` + `scripts/update.ps1` — pull/build/install/version-diff/reload-hint cycle. `skills/update-claude-skills/SKILL.md` v0.1.0 — thin wrapper, detects platform, calls script. `hermes/mapping.yaml` — mode: skip (Claude-Code-only). Build+install verified: `dist/update-claude-skills.skill` (1942 bytes), `~/.claude/skills/update-claude-skills/SKILL.md` v0.1.0, SKIPPED.md lists reason. Hermes rebuild: 24 skills (13 auto, 2 manual, 9 skip, 0 pending).
 **Next action:** ⚠️ **ARCH-note (2026-05-07, после ревизии `.factory/factory.yaml`):** таска НЕ дубликат factory L1 — она Layer 2 citizen в дизайне factory. `factory.yaml` line 83-91 уже включает `claude-skills` как компонент с `post_install: 'bash {target}/scripts/install.sh'`. **Recommended shape (вариант B с оглядкой на A):** реальная update-логика — в `scripts/update.{ps1,sh}` (рядом с `install.{ps1,sh}`), один источник истины. Скил `update-claude-skills` — короткий wrapper, на триггер вызывает нужный скрипт по `active-platform`. Когда L1 Go-бинарь дойдёт — `factory update` использует те же скрипты без duplication.
 
 1) Скрипты: `scripts/update.ps1` + `scripts/update.sh` в корне репы. Логика: pull/build/install в трёх местах (claude-skills + .common/lib/projects-meta-mcp + .common/lib/interns-mcp), version-diff, reload-hint. **Возможность совмещения с `[install-ps1]`:** добавить `--prune` flag сразу в `update.{ps1,sh}` и в `install.{ps1,sh}` (там 1 of 3 criteria из install-ps1). 2) Скил-структура: `skills/update-claude-skills/SKILL.md`, frontmatter `version: 0.1.0`, описание с триггерами («обнови claude-skills», «sync claude-skills»). Скил — wrapper, не содержит логику. 3) Build + install: `pwsh ./scripts/build.ps1 update-claude-skills`, `pwsh ./scripts/install.ps1 update-claude-skills`. 4) Smoke на текущей машине — должно быть no-op (всё свежее, идемпотентность). 5) Mapping в `hermes/mapping.yaml` (`mode: skip` — Claude-Code-only) или `mode: manual` если параллельно делаем Hermes-twin (логика та же, но Hermes-side скрипт другой — там не install.sh а skill_manage). 6) Обновить `.factory/factory.yaml` post_install: `bash {target}/scripts/update.sh` (или `pwsh ... update.ps1` если factory детектит OS) — отдельный 1-line PR в `.factory`. 7) Doc `.wiki/concepts/claude-skills-update-flow.md` (опционально слить с `install-cross-platform.md` из `[install-ps1]`). 8) `tasks_close`.

+# update-claude-skills
+
+> One command to bring your claude-skills installation fully up to date — repo, MCP servers, skills, and version diff.
+
+## When this runs
+
+**On explicit trigger** — when the user says any of: `update claude-skills`, `sync claude-skills`, `обнови claude-skills`, `обнови всё`, `update skills`, or close variants asking to refresh the skills catalog.
+
+**Never** automatically at session start (that's `pulling-before-work`'s job for the git part). This skill is for the full uplift cycle — git + build + install + diff — which is heavier and intentional.
+
+## Process
+
+### 1. Detect platform
+
+Determine which script to run:
+
+- **Windows (PowerShell):** `pwsh ~/projects/claude-skills/scripts/update.ps1`
+- **Linux / macOS:** `bash ~/projects/claude-skills/scripts/update.sh`
+
+Use the `active-platform` skill's detection if available. Otherwise:
+- If `$env:OS` is `Windows_NT` or `IsWindows` is true → PowerShell path.
+- Otherwise → bash path.
+
+If the repo is at a non-default location, adjust the path accordingly (the user may have cloned to `~/projects/claude-skills` or another directory — check `git -C <path> rev-parse --is-inside-work-tree` if unsure).
+
+### 2. Run the update script
+
+Execute the appropriate script. Show the output to the user — it contains version diffs and reload hints.
+
+If the script exits non-zero, **stop** and show the error. Common failures:
+- `git pull --ff-only` fails → the repo has diverged or there's no upstream. The user must resolve manually.
+- MCP build fails → show the error, suggest running `npm run build` / `pip install -e .` manually.
+
+### 3. Offer to reload MCP servers
+
+If the script output mentions "MCP servers rebuilt" or "source changed":
+
+> MCP servers were rebuilt. Run `/reload-mcp` to reload them.
+
+If no MCP changes:
+
+> Skills updated. Start a new session (or `/clear`) for changes to take full effect.
+
+### 4. Offer to run new setup skills
+
+If the script detected new `setup-*` skills that aren't yet installed:
+
+> New setup skills available: `<list>`. Want me to run any of them?
+
+The user decides — never auto-run setup skills.
+
+## What the scripts do
+
+The update scripts (`scripts/update.sh` and `scripts/update.ps1`) handle:
+
+1. **git pull --ff-only** in `~/projects/claude-skills/` (stash if dirty, pop after).
+2. **Conditionally rebuild projects-meta-mcp** — if `~/projects/.common/lib/projects-meta-mcp/` has a `.git` directory and source changed (`git pull` fetched new commits), run `npm run build`.
+3. **Conditionally rebuild interns-mcp** — same pattern, `pip install -e .`.
+4. **Install all skills** via `install.sh` / `install.ps1`.
+5. **Show version diff** — before/after `version:` frontmatter for each skill.
+6. **Print reload hints** — `/reload-mcp` if MCP changed, new session otherwise.
+
+## Out of scope
+
+- **Greenfield bootstrap** — use `project-bootstrap` for first-time setup on a new machine.
+- **`--prune` flag** — removing skills not in `skills/` from `~/.claude/skills/`. Tracked separately in `[install-ps1]`.
+- **Hermes-side update** — `hermes-installer-skill` handles the Hermes/Linux factory path.
+- **Auto-run setup skills** — the user decides which new setup skills to configure.
+
+## Cross-agent applicability
+
+Pure orchestration — calls platform scripts, no Claude-specific tool references. Hermes-mappable as `mode: skip` (Claude-Code-only; Hermes uses `hermes-installer-skill` instead).
