Guides the creation of Browser4 plugins from requirements gathering through deployment. Use when the user wants to create, build, scaffold, or extend Browser4 with a new plugin — whether for CAPTCHA solving, media processing, content conversion, page category detection, custom RPA actions, or new LLM agent tools.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Browser4 Plugin Development
## Quick Start
```bash
mvn -pl browser4-pdk install # install the PDK parent POM once
mvn archetype:generate -DarchetypeGroupId=ai.platon.pulsar \
-DarchetypeArtifactId=browser4-plugin-archetype # scaffold the plugin project
mvn -f <artifactId>/pom.xml package # build the plugin JAR
```
Deploy the JAR to the server's `plugins/` directory (or POST it to `http://localhost:18182/api/plugins/install`) and restart — the plugin is auto-discovered. Prerequisites: JDK 17+, Maven 3.9+, and access to the `browser4-pdk` parent POM.
For the full walkthrough — requirements clarification, mount-point implementation, services/config, manifest, tests, build & deploy — see [Step-by-Step Workflow](references/workflow.md).
## When to Use
Use this skill when the user wants to **create, build, scaffold, or extend a Browser4 plugin** — CAPTCHA solving, media processing, content conversion, page-category detection, custom RPA actions, or new LLM agent tools. It is the deep guide (mount points, services, tests, deployment); for plugin *code* scaffolding inside this repo use the `browser4-coding` skill.

How to install
mdr add platonai/browser4/browser4-plugin@sha256:fb8e92323d117423The line at the top of this page pins the label git:20261003.fde398d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
