codex-launcher AGENTS.md

codex-launcher AGENTS.md is an instructions file for Codex, OpenCode from x0x0b/codex-launcher. It costs 619 tokens per session, scanned A, original, MIT.

Development instructions for a Kotlin plugin that adds Codex-related actions to IntelliJ-based IDEs. They explain the source layout, Gradle commands, coding style and tests.

In plain words
What is it for?
Use them when changing plugin actions, settings or services, or when running its JUnit tests and creating an installable plugin package.
Why use it?
They tell an agent how the plugin is organized and how to build, test, package and manually run it without guessing.

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

codex-launcher AGENTS.md 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.

Repository Guidelines

Project Structure & Module Organization

  • src/main/kotlin/com/github/x0x0b/codexlauncher/ — plugin actions (*Action), terminal service, CLI arg builder, settings UI/options.
  • src/main/resources/META-INF/plugin.xml — plugin metadata; icons live in src/main/resources/icons/.
  • src/test/kotlin/com/github/x0x0b/codexlauncher/ — JUnit tests mirroring main packages (e.g., CodexArgsBuilderTest, InsertPayloadResolverTest).
  • Build outputs land in build/; packaged zips in build/distributions/.

Build, Test, and Development Commands

  • ./gradlew buildPlugin — compile and package the IntelliJ plugin zip into build/distributions/.
  • ./gradlew runIde — launch the sandbox IDE with the plugin for manual checks.
  • ./gradlew test — run the JUnit suite; use --tests com.github.x0x0b.codexlauncher.* to target classes.
  • ./gradlew clean — remove build outputs before a fresh run (optional).

Coding Style & Naming Conventions

  • Kotlin 2.2, JVM 21; follow standard Kotlin style (4-space indent, trailing commas where helpful, immutable vals preferred).
  • Public APIs and services should include concise KDoc; logger via com.intellij.openapi.diagnostic.logger.
  • Classes/objects use PascalCase; enums like Model, Mode; actions end with Action; tests end with Test.
  • Keep IntelliJ platform threading rules in mind (UI changes on EDT; services stay light).

Testing Guidelines

  • Tests live under src/test/kotlin and use JUnit 4 (@Test); mirror package paths.
  • Favor fast, isolated unit tests for CLI arg building, action routing, and terminal handling.
  • When adding behavior, pair with a regression test; name methods descriptively (methodName_condition_expected).
  • For manual verification, prefer ./gradlew runIde to exercise toolbar actions and settings UI.

Commit & Pull Request Guidelines

  • Follow recent Conventional Commit style seen in history (feat:, fix:, optional issue refs like (#95)); keep subject in imperative, ≤72 chars.
  • Include PR summary, rationale, and testing notes; attach screenshots/GIFs for UI changes and mention affected IDE versions (targets 2024.2+).
  • Update plugin.xml change notes when user-facing behavior shifts; align version in build.gradle.kts as needed.

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.
