imgui-java: Instructions file for Codex

AGENTS.md

imgui-java AGENTS.md is an instructions file for Codex, OpenCode from SpaiR/imgui-java. It costs 3,576 tokens per session, scanned A, original, MIT.

Repository instructions for AI coding agents working on imgui-java, a Java binding that lets Java programs use Dear ImGui, a graphical user-interface library. They cover the project layout, build and test process, generated code, and upgrades.

In plain words
What is it for?
Use them when adding or changing bindings, updating Dear ImGui or extensions, running builds and tests, or changing project submodules.
Why use it?
They explain which files are generated, which companion rules to read, and how to avoid breaking the Java, native-code, and code-generation workflow.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is SpaiR/imgui-java's own configuration. It tells Codex and OpenCode how to work on imgui-java itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything imgui-java configures →

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

imgui-java 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 2mo 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.

AGENTS.md

Guidance for AI coding agents working on imgui-java.

This file is the operational guide: what the repo is, how to build it, the procedure for upgrading submodules, and the codegen-internals conventions. The everyday conventions and "don't"s live in companion files — read them too:

  • .claude/rules/guardrails.md — what not to do. Covers the golden rules (never edit src/generated/java/, never commit bin/ natives), the JNI contract, Java 8 compatibility on consumed classes, doclint pitfalls, dependency hygiene, AST drift, and the rule against mixing submodule bumps with feature work.
  • .claude/rules/codestyle.md — Java style for imgui-binding/, imgui-lwjgl3/, imgui-app/ (formatting, naming, modifiers, imports, javadoc, wrapper class shape, binding-source annotations). Authoritative copy is config/checkstyle/checkstyle.xml.
  • .claude/docs/patterns.md — recurring patterns when adding to the binding (the codegen loop, annotated stubs, struct wrappers, out-parameter Im* wrappers, module boundaries, application lifecycle).
  • CONTRIBUTING.md — the human-facing contributor guide, and the authority on everything commit- and release-shaped: the conventional-commit types/scopes tables, PR title and body rules (PRs are squash-merged, so the PR title must be a valid commit header), label mapping, the versioning scheme (version tracks Dear ImGui, so it can never signal a break), the release procedure, and — importantly — the Co-authored-by trailer rule for AI-assisted commits plus the "you are responsible for the change" rule. Read it before writing a commit message or opening a PR.

If anything below conflicts with those files, the dedicated file wins — update it there, not here.

What this repo is

JNI-based Java binding for Dear ImGui + extensions (ImPlot, ImNodes, ImGuizmo, imgui-node-editor, imgui-knobs, imgui-file-dialog, imgui-text-edit, imgui-club). Multi-module Gradle build, published as io.github.spair:imgui-java-{binding,lwjgl3,app}. Java is codegen-driven: annotated stubs in imgui-binding/src/main/java/, expanded by the Spoon-based generator in buildSrc/ into imgui-binding/src/generated/java/ — both trees committed.

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.
