This bootstrap establishes how to access skills and how to translate platform tool names into equivalent operations on Claude Code, Antigravity CLI (`agy`), Gemini CLI, and Codex CLI.\n\n## How to Access Skills\n\n- **Claude Code:** Use the `Skill` tool. When invoked, the skill content is loaded and presented to follow directly.\n- **Antigravity CLI (`agy`):** Skill metadata (name + description) is auto-loaded into the system prompt at session start. When triggers fire, use `view_file` to load `skills/<skill-name>/SKILL.md` from the plugin directory, then follow its instructions.\n- **Gemini CLI (Legacy):** Skill metadata is loaded into system prompt. Use `read_file` to load `skills/<skill-name>/SKILL.md`.\n- **Codex CLI:** Skill index and trigger phrases are inlined in `AGENTS.md` at install time. Follow the skill body directly when a trigger phrase fires.\n\n## Platform Tool Mapping\n\narkhe SKILL.md files reference core agent primitives. On each platform, substitute the equivalent operation from this table.\n\n| Primitive / Claude tool | Antigravity CLI (`agy`) equivalent | Gemini CLI (Legacy) equivalent | Codex CLI equivalent |\n|---|---|---|---|\n| `AskUserQuestion` | `ask_question` (native interactive modal with chip UI options) | Ask a plain-text question with numbered choices and await reply. | Plain-text question with numbered choices. |\n| `TaskCreate` / `TaskUpdate` | `manage_task` or inline TODO list rendered on each turn | Inline TODO list rendered on each turn | Inline TODO list rendered on each turn |\n| `EnterPlanMode` / `ExitPlanMode` | Native `--mode plan` / `accept-edits` mode | Announce plan mode and gate writes on approval | Announce plan mode and gate writes on approval |\n| Skill tool (`Skill`) | `view_file` on `skills/<name>/SKILL.md` | `read_file` on `skills/<name>/SKILL.md` | Skill content inlined in `AGENTS.md` |\n| Agent tool (`subagent_type`) | `invoke_subagent` / `define_subagent` (native background/concurrent subagent execution) | Inline agent prompt into current session | Inline agent prompt into current session |\n\n## Command Naming Across Platforms\n\nCommands ship from the same `plugins/<plugin>/commands/<name>.md` source on every platform, but the slash-command syntax differs:\n\n| Platform | Form | Example |\n|---|---|---|\n| Claude Code | `/<plugin>:<command>` (plugin-namespaced) | `/core:think` |\n| Antigravity CLI (`agy`) / Gemini CLI | `/<command>` (or `agy plugin` commands) | `/think` |\n| Codex CLI | Trigger phrase in chat (no slash) | \"think through whether to use Postgres or Redis\" |\n\nWhen this skill or other arkhe docs refer to `core:think`, `core:debug`, etc., resolve them through this table — same command, platform-specific invocation.\n\n## Subagent-Heavy Commands\n\nSix arkhe commands dispatch subagents on Claude Code and Antigravity CLI (`agy`). On legacy Gemini and Codex CLI, they run inline with the agent's prompt collapsed into the command body.\n\nThe affected commands:\n\n- `core:debug` (with `--deep`)\n- `core:think`\n- `core:research`\n- `core:double-check` (with `--deep`)\n- `spring-boot:spring-review`\n- `spring-boot:verify-upgrade`\n\n## Instruction Priority\n\n1. **User's explicit instructions** (CLAUDE.md, GEMINI.md, AGENTS.md, direct requests) — highest priority\n2. **arkhe skills** — override default system behavior where they conflict\n3. **Default system prompt** — lowest priority\n\nIf `CLAUDE.md`, `GEMINI.md`, or `AGENTS.md` says \"do not use TDD\" and a skill says \"always use TDD,\" follow the user's instructions. The user is in control.\n\n## Where Skills Live\n\n- **Canonical source:** `plugins/<plugin>/skills/<skill>/SKILL.md`\n- **Claude Code:** loaded via `.claude-plugin/marketplace.json`\n- **Antigravity CLI / Gemini CLI:** loaded via `plugins/<plugin>/plugin.json` or `.gemini-extensions/<plugin>/plugin.json` (skills directory is a symlink to the canonical source)\n- **Codex CLI:** loaded via `.codex-marketplace/<plugin>/AGENTS.md` (skill index synthesized at build time; full content via symlinked `skills/`)\n\nSkill bodies are not duplicated across platforms. One file, cross-platform support.\n","tagline":"Use when starting any conversation - establishes how arkhe skills bootstrap on Claude Code, Antigravity CLI (agy) / Gemini CLI, and Codex CLI, and maps Claude-only tools (AskUserQuestion, TaskCreate, EnterPlanMode, the Skill tool, the Agent tool) to their cross-platform equivalen","category":"design-creative","commerce":{"type":"unknown","billing":"unknown","amount":null,"currency":null,"sourceUrl":null,"checkedAt":null,"runtime":"unknown","purchaseUrl":null,"checkout":"external","purchaseRequiresUserConsent":true},"tags":["agent-skill"],"author":"joaquimscosta","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"joaquimscosta/arkhe-claude-plugins","creatorName":"joaquimscosta","creatorUrl":"https://github.com/joaquimscosta","sourceUrl":"https://github.com/joaquimscosta/arkhe-claude-plugins/tree/main/plugins/core/skills/using-arkhe-skills","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/joaquimscosta-using-arkhe-skills#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
