agent-native

Designs agent-native applications where agents are first-class citizens with full tool parity, atomic primitives, and explicit completion signals. Covers tool design, context injection, agent-to-UI communication, and mobile checkpoint/resume patterns. Use when architecting an agentic system, designing tool surfaces, building agent-aware UI, implementing context.md patterns, or asking "how do I make my app agent-native."

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/mblode/agent-skills --skill agent-native
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads agent-native automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Agent-Native

Agent-native applications treat agents as first-class users. Whatever a human can do through the UI, an agent can achieve through tools. Features are outcomes described in prompts, achieved by an agent with atomic tools, operating in a loop until done.

Reference Files

FileRead When
references/core-principles.mdDefault: understanding Parity, Granularity, Composability, and Emergent Capability
references/tool-design.mdDesigning tools — atomic primitives, CRUD, domain tools, dynamic discovery
references/files-and-context.mdState management — entity directories, context.md, context injection, files vs database
references/agent-ui-communication.mdBuilding agent feedback — completion signals, partial completion, event types
references/mobile-specifics.mdiOS/mobile — checkpoint/resume, iCloud storage, background execution

Core Principles

  • Parity — Agent can achieve anything users can do through the UI. Build a capability map; close every gap.
  • Granularity — Tools are atomic primitives. Judgment and decision logic live in prompts, not tool implementations. To change behavior, edit prose, not code.
    # Anti-pattern: workflow-shaped tool
    analyze_and_organize(folder)  # bundles judgment into code
    
    # Agent-native: atomic primitives
    list_files(folder) → read_file(path) → move_file(src, dst) → write_file(path, content)
    # The agent decides what to move and where — judgment stays in the prompt
    
  • Composability — New features = new prompts. With atomic tools and parity, you describe an outcome and the agent loops until it's achieved.
  • Emergent capability — The agent handles requests you didn't design for. Observe what users ask; formalize patterns that emerge.
  • Improvement over time — State persists via context files. Prompts can be updated for all users without shipping code.

Design Workflow

  1. Capability audit — Map every UI action to an agent equivalent. Close any gap. Read core-principles.md.
  2. Tool surface design — Define atomic primitives for every entity (CRUD). Add domain tools only for vocabulary, guardrails, or efficiency. Read tool-design.md.
  3. Context and state planning — Design the context.md file, entity directory structure, and system prompt injection. Read files-and-context.md.
  4. Agent-UI feedback design — Define completion signals, event types, shared workspace, and approval gates. Read agent-ui-communication.md.
  5. Validate — Run the checklist below. Describe an unbuilt outcome and test whether the agent can figure it out.

Design Checklist

Copy and track during design:

Agent-native design progress:
- [ ] Capability map: every UI action has an agent equivalent
- [ ] Tools are atomic primitives (judgment in prompts, not tools)
- [ ] Every entity has full CRUD tool coverage
- [ ] System prompt injects available resources and capabilities
- [ ] Agents and users share the same data space
- [ ] Agent actions reflect immediately in UI
- [ ] Completion is signaled explicitly (no heuristic detection)
- [ ] External APIs use dynamic capability discovery where possible
- [ ] Approval model matches stakes and reversibility
- [ ] Ultimate test: describe an unbuilt outcome — can the agent figure it out?

Validation Loop

Before shipping, verify:

  1. Capability coverage — Pick 5 random UI actions; confirm the agent can accomplish each without touching code.
  2. Tool atomicity — Review every tool; if it contains if/else decision logic, split it.
  3. Context completeness — Clear the agent's context and start a session; does it still know what exists?
  4. End-to-end scenario — Give the agent an outcome you never explicitly built. Does it compose tools to get there?

Anti-Patterns

  • Agent as router — Agent routes to your code instead of acting with judgment; you've built a dispatcher, not an agent.
  • Workflow-shaped tools — analyze_and_organize bundles decision logic into a tool; break into read_file, move_file, write_file.
  • Orphan UI actions — User can do something the agent can't; breaks parity.
  • Context starvation — Agent doesn't know what exists; inject resources and capabilities into every system prompt.
  • Gates without reason — Domain tool is the only path when primitives should also work; default to open.
  • Heuristic completion detection — Detecting done via consecutive idle iterations; require an explicit completion tool call.
  • Static API mapping — 50 tools for 50 endpoints; use discover + access instead.

FAQ

What does the agent-native skill do?

Designs agent-native applications where agents are first-class citizens with full tool parity, atomic primitives, and explicit completion signals. Covers tool design, context injection, agent-to-UI communication, and mobile checkpoint/resume patterns. Use when architecting an agentic system, designing tool surfaces, building agent-aware UI, implementing context.md patterns, or asking "how do I make my app agent-native."

How do I install agent-native?

Run npx skills add https://github.com/mblode/agent-skills --skill agent-native in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/agent-native/ (personal) or .claude/skills/agent-native/ (project).

Which AI agents can use agent-native?

Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.

Is agent-native safe to install?

No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
