verify-eap-compatibility

verify-eap-compatibility is a skill for Claude Code, Codex from flutter/flutter-intellij. It costs 29 tokens per session (370 once invoked), scanned A, original, BSD-3-Clause.

A compatibility-checking guide for IntelliJ Platform plugins against upcoming releases and EAP builds. EAP means an early test version released before the stable version.

In plain words
What is it for?
Use it to test a plugin against the latest EAP, check its supported version bounds, and identify changes needed for compatibility.
Why use it?
It helps reveal broken APIs, compilation problems, test failures, and version-range issues before a new IntelliJ release reaches users.

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

verify-eap-compatibility scanned grade A with 0 findings 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 4d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Skill: Plugin Compatibility & EAP Verification

You are tasked with ensuring the plugin remains compatible with the latest IntelliJ Platform releases and EAP (Early Access Program) builds.

Objective

Ensure the plugin remains compatible with the latest IntelliJ Platform releases and EAP (Early Access Program) builds.

Workflow Instructions

1. Target EAP

  • Temporarily update gradle.properties to target the latest IntelliJ Platform EAP version.

2. Run Verification

  • Run ./gradlew testClasses to ensure the project compiles against the EAP.
  • Execute ./gradlew verifyPlugin to check for binary incompatibilities or broken API usages in the new version.
  • Run ./gradlew test to check for functional regressions with the EAP.

3. Check Bounds

  • Review plugin.xml for <idea-version since-build="..." until-build="..."/>. Ensure until-build is open-ended or appropriately set for the new version.

4. Resolve Issues

  • Fix any compilation errors or verification warnings specific to the new platform version.

5. Report & Review

  • Summarize any required changes or blockers for supporting the new version.
  • Test Location: Explicitly state where in the IDE the user should go to test the changed functionality (e.g., "Go to Preferences > Languages & Frameworks > Flutter").
  • Action: Ask the user to review the compatibility fixes closely.
  • Do not commit or push.
  • Provide a suggested Git commit message (e.g., "Fix EAP compatibility: Resolve invalid until-build").
Changes

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.
