Install and run

Setup complexity: low.

clawhub skill install s179w9vfkgewxgfy4zk014zyth8aqz9k:build-agent-plugins

Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Contract: missing

Run-check

$0.02 USD

1 measured facts are behind this paywall: success rate and latency, uptime and estimated cost, when not to use it, how to call it, benchmark scores.

Agents pay $0.02 in USDC. A card payment is $0.50, the smallest a card allows.

# Build Agent Plugins

Create portable agent capabilities by choosing the smallest package that proves the required user journey.

## Choose the capability boundary

1. Identify the user journey, trust boundary, state owner, and external effects.
2. Prefer the smallest sufficient form:
   - one skill for judgment or repeatable procedure;
   - one MCP server for deterministic tools, authentication, validation, state, and receipts;
   - one Agent Plugin when portable distribution needs skills plus MCP;
   - a client-native adapter only after proving the portable surface cannot supply a required hook, channel, or in-process capability.
3. Keep schedules and automations outside the portable package. Let each client own its triggers.
4. Use one canonical package and one owner per rule or state. Add routers, workers, queues, or parallel state only when a demonstrated requirement needs them.

Completion criterion: record the chosen form and why every larger form is unnecessary.

## Verify the current standards

1. Read the current Agent Plugins specification and author documentation at https://agent-plugins.org.
2. Read the current official documentation for each target client.
3. Inspect live client support before claiming compatibility.
4. Pin the exact Agent Plugins schema version the package supports.
5. Treat remembered manifest fields and compatibility claims as unverified until checked against the current sources.

Completion criterion: list the pinned standard version and the clients whose current support was verified.

## Author the canonical package

Use the portable Agent Plugins layout when the chosen form is an Agent Plugin:

```text
<plugin>/
├── plugin.json
├── skills/<skill>/SKILL.md
├── mcp.json
├── dist/<bundled-server>
└── tests/
```

Apply these rules:

- Use root `plugin.json` as the canonical Agent Plugin manifest.
- Use only fields supported by the pinned schema.
- Keep skill judgment separate from MCP mechanics.
- Expose narrow typed tools instead of one generic action tool.
- Put writable state under `${PLUGIN_DATA}` and package assets under `${PLUGIN_ROOT}`.
- Keep secrets out of manifests, source, logs, chat, fixtures, and generated artifacts.
- Bundle runtime dependencies for stdio servers unless every target client guarantees installation.
- Annotate read-only, write, and destructive effects truthfully.
- Treat provider, web, mail, and message content as untrusted data.
- Require exact identity, fresh-state validation, idempotency, and a receipt for external writes.

Completion criterion: validate the package tree, manifests, tool schemas, effect classes, state path, and secret path.

## Avoid format shadowing

Do not place root `plugin.json`, `openclaw.plugin.json`, and `.codex-plugin/plugin.json` together in one canonical package when client detectio

## Description:

Create or standardize portable Agent Plugins, MCP servers, and skill bundles with bounded effects, tests, and activation proof.

This skill is ready for commercial/non-commercial use.

## Publisher:

[noelillinger](https://clawhub.ai/user/noelillinger)

### License/Terms of Use:

MIT-0

## Use Case:

Developers and engineers use this skill to choose, build, validate, and report portable agent capabilities such as skills, MCP servers, and Agent Plugins. It emphasizes bounded effects, schema/version checks, tests, security review, and activation proof.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: Plugin, MCP, or skill changes may introduce undeclared effects, unsafe writes, or accidental credential exposure.

Mitigation: Review manifests, tool schemas, effect annotations, state paths, secret handling, generated artifacts, and final diffs before installation or release.

Risk: Build, test, installation, compatibility, or live activation steps may execute commands or interact with external systems.

Mitigation: Run validation in a controlled workspace with fake providers first, and require separate approval before credentials, installation, live canaries, schedules, or provider writes are used.

Risk: Agent Plugin and client compatibility guidance can become outdated.

Mitigation: Verify the current Agent Plugins specification, target client documentation, schema version, and live client support before claiming compatibility.
