release-plugin

A release checklist for the Flutter IntelliJ plugin, an extension that adds Flutter development support to JetBrains IDEs. It covers dependency versions, supported IDE versions, changelogs, verification, and building the release ZIP.

In plain words
What is it for?
Use it to prepare and verify a new plugin release, including updating Dart and IntelliJ compatibility and creating the release artifact.
Why use it?
It organizes the version-release work so compatibility settings, documentation, tests, and the distributable file are updated together.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

release-plugin scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Skill: Release Plugin

You are tasked with preparing a new version release of the flutter-intellij plugin (e.g., releasing 95.0.0).

Objective

Systematically update plugin dependencies, compatibility parameters, and CHANGELOG.md, verify tests and plugin structure, and build the release zip artifact.


Workflow Instructions

1. Update Platform & Dependency Parameters

  • gradle.properties:
    • Update dartPluginVersion to the latest public Dart plugin release version. Fetch the latest version from JetBrains Marketplace (e.g. via curl -s "https://plugins.jetbrains.com/api/plugins/6351/updates?size=1" | jq -r '.[0].version' or by checking JetBrains Marketplace Dart Plugin) and set dartPluginVersion in gradle.properties to that version (e.g., dartPluginVersion= 508.0.0).
    • If dropping support for older platform versions, update sinceBuild to the new lower bound (e.g., sinceBuild=252). Note: untilBuild is omitted for open-ended platform compatibility.
  • New Platform Version Compatibility & Baselines:
    • When supporting/verifying a new platform release (e.g., IntelliJ 2026.3 / build 263):
      • Update the verification loop in tool/github.sh (for version in ...; do).
      • Run ./tool/update_baselines.sh to generate or update the plugin verifier baseline files in tool/baseline/<version>/verifier-baseline.txt.
  • JxBrowser License Key:
    • Ensure resources/jxbrowser/jxbrowser.properties is present (copy from local environment if creating a new git worktree).

2. Fix API & Dependency Compatibility

  • Check for compilation errors or API signature changes introduced by the updated dependencies (e.g., websocket/DTD exception handling changes in FlutterInitializer.java and FlutterApp.java).
  • Run ./gradlew testClasses to confirm the codebase compiles against updated dependencies.

3. Update Changelog (CHANGELOG.md)

  • Compatibility Changes PR:
    • Document compatibility updates under ### Changed in CHANGELOG.md with the PR reference (e.g., - Removed upper build constraint (\untilBuild`) for open-ended platform compatibility. (#9063)`).
  • Release Version Bump:
    • Rename ## Unreleased to ## <VERSION>.0.0 (e.g., ## 95.0.0).
    • Ensure all user-facing changes since the last release are categorized and tagged with PR numbers.
    • Insert a fresh empty ## Unreleased block at the top with:
      ## Unreleased
      
      ### Added
      
      ### Changed
      
      ### Removed
      
      ### Fixed

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

release-plugin is a skill published in the GitHub repository flutter/flutter-intellij (2,013 stars, last pushed yesterday), licensed BSD-3-Clause. It adds 30 tokens to every session and 1,016 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
