plan-change
Turn a feature request into a minimal, file-level implementation plan before any code.
git clone --depth 1 https://github.com/ruvnet/metaharness /tmp/plan-change && cp -r /tmp/plan-change/kimi-k3-harness/.claude/skills/plan-change ~/.claude/skills/plan-changeSKILL.md
# plan-change Produce an implementation plan for a requested change. 1. Restate the goal in one sentence. 2. List the files to touch and why. 3. Name the smallest interface that satisfies it. 4. Flag anything that ripples beyond three files or widens a permission. Hand the plan to the implementer; do not write code in this step.
Diff two scaffolded harnesses (ADR-031). Reports manifest meta drift + host list + per-file fingerprint changes (added/removed/changed). Exits 0 IDENTICAL, 1 DRIFT, 2 missing manifest. Use --bundle for the ADR-031 schema-1 JSON envelope.
Scaffold your own focused AI agent harness — pick host (Claude Code, Codex, pi.dev, Hermes), template, agents, skills, and ship a npm-publishable harness with its own npx CLI. Use when a user asks to "create my own agent harness", "scaffold a harness", "make a custom Claude Code plugin like ruflo", or "build a vertical AI assistant for X".
Kernel-version skew check (ADR-027). Reports manifest surface + manifest kernel + installed kernel + verdict (match/patch-diff/minor-diff/major-diff). Exits 1 on minor/major skew with a copy-pasteable `npm install @metaharness/kernel@X.Y.Z` next step. Exits 2 if no .harness/manifest.json at path.
Health-check the harness: kernel load, MCP wiring, memory backend, host adapter.
Evolve this harness with Darwin Mode — frozen model, evolving harness (real, sandboxed, safety-gated).
Scaffold a ready-made AI agent harness in one command from the 19 published @metaharness/* example packages — 9 host integrations (Claude Code, Codex, Hermes, pi.dev, OpenClaw, RVM, Copilot, OpenCode, GitHub Actions) + 10 vertical pods (devops, research, trading, support, legal, coding, education, sales, gaming, repo-maintainer).
GCP Secret Manager integration: validate setup, fetch values, or confirm an NPM_TOKEN is non-revoked via `npm whoami`. Used for publish-time token rotation without long-lived keys in CI.
List the available harness templates and what each one ships with. Use when the user asks "what templates are available", "what verticals does the harness generator support", or "show me what I can scaffold".
