Problem

The upstream OpenClaw skills subsystem (marketplace, skill installation, skill
bins trust, per-channel skill filters) is dead code in RemoteClaw. The skills/
directory was already removed, but references persist across 52 source files
(131 occurrences), 18 test files (42 occurrences), and 38 doc files (158
occurrences).

Scope

Remove all skills-related dead code. Key areas:

CLI & onboarding

• --skip-skills flag (register.onboard.ts:82)
• --node-manager flag (register.onboard.ts:85) — was the npm/pnpm/bun choice for skill package installation
• skipSkills in OnboardOptions type (onboard-types.ts:144)
• NodeManagerChoice type and nodeManager option (onboard-types.ts:87,147)
• resolveNodeManagerOptions() helper (onboard-helpers.ts:298)
• skipSkills passthrough in local.ts:288 and local/output.ts:18,33

Node host / execution engine

• SkillBinsProvider, SkillBinsCache, SkillBinTrustEntry types and classes (runner.ts, invoke-types.ts, invoke.ts, invoke-system-run.ts)
• autoAllowSkills flag threading (invoke-system-run.ts, invoke.ts)
• skills.bins RPC call (runner.ts:225)

Config / schema

• skills arrays in zod schemas (zod-schema.providers-core.ts — 5 occurrences)
• skills in channel config types (types.telegram.ts, types.slack.ts, types.discord.ts, types.irc.ts, types.agents.ts)
• "skills" in configure.shared.ts menu
• skills in schema.help.ts, schema.labels.ts, schema.hints.ts

Channel integrations

• skillFilter in Slack (slash.ts, dispatch.ts, channel-config.ts)
• skillFilter in Telegram (bot-message-context.ts, group-config-helpers.ts, bot-message-dispatch.ts, bot-native-commands.ts)
• skills in Line config (line/types.ts, line/config-schema.ts)
• skills in Discord (allow-list.ts, native-command.ts, message-handler.*.ts)

Plugins

• skills field in manifest (manifest.ts:16,73,90)
• "skill" command in commands list (commands.ts:52)
• skills in manifest registry (manifest-registry.ts:31,124)

Other

• skillFilter in auto-reply types (auto-reply/types.ts:50)
• skills in agent scope (agent-scope.ts:29,132)
• skillStatus / SkillStatusLike in status-all (status-all.ts, diagnosis.ts)
• skills in gateway protocol schemas
• Fun update message referencing skills in update-command.ts:64

Docs — 38 files with skills references (separate pass, may split into follow-up)

Approach

Follow the pattern established by recent gut(*) commits (#547–#554). Remove
code in layers: types → consumers → CLI flags → config schema → tests → docs.
Run pnpm check and pnpm test after each layer.

Acceptance Criteria

• No skill references in src/ except intentional comments explaining removal
• No --skip-skills or --node-manager CLI flags
• No NodeManagerChoice type or resolveNodeManagerOptions() helper
• pnpm check passes
• pnpm test passes
• Coverage thresholds maintained
