recaf-mcp: Instructions file for Codex

AGENTS.md

recaf-mcp AGENTS.md is an instructions file for Codex, OpenCode from Naptila/recaf-mcp. It costs 887 tokens per session, scanned A, original, MIT.

Repository instructions for a Recaf 4 plugin and its Python MCP bridge. Recaf is a tool for inspecting and modifying Java applications, while the bridge lets AI tools communicate with it.

In plain words
What is it for?
Building and testing the Java plugin and Python bridge while following the project’s source, documentation, and scratch-file rules.
Why use it?
They identify which dependency versions and files are authoritative, reducing compatibility mistakes between the plugin and the running Recaf JAR.

Instructions file for CodexOpenCode

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

This is Naptila/recaf-mcp's own configuration. It tells Codex and OpenCode how to work on recaf-mcp 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 recaf-mcp 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

recaf-mcp 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.

Repository Guidelines

Scope and Sources of Truth

This repository integrates with Recaf 4 but does not vendor Recaf source or documentation.

  • recaf-mcp-plugin/build.gradle pins recafVersion; it is the compile-time compatibility baseline.
  • The generic JAR selected by RECAF_JAR is the runtime compatibility target.
  • Recaf's developer documentation is a rolling upstream reference. Verify version-sensitive APIs against the pinned dependency, source for that revision, and the build.
  • tmp/ is ignored local scratch space. Never depend on its contents or commit copied Recaf documentation, sample targets, generated output, or model notes.

Project Structure

  • recaf-mcp-plugin/ contains the Java Recaf plugin and Worker implementation. Production code is under src/main/java/me/naptila/recafmcp/, resources are under src/main/resources/, and matching JUnit tests are under src/test/java/.
  • recaf-mcp-bridge/ contains the Python MCP stdio bridge and Worker session supervisor. Production modules are under src/; pytest tests are under tests/.
  • README.md and README-ZH.md are the public user documentation.

Build and Test Commands

Run commands from the relevant module directory.

For the plugin:

  • ./gradlew build compiles the plugin, runs all JUnit tests, and creates the plugin JAR in build/libs/.
  • ./gradlew test runs the Java test suite.
  • ./gradlew runRecafHeadless launches the pinned headless development runtime.
  • ./gradlew -q javaToolchains lists detected JDK installations.

The Gradle wrapper is authoritative. The build uses a JDK 25 toolchain and emits Java 22-compatible bytecode.

For the bridge:

  • uv sync --frozen installs the locked Python environment.
  • uv run pytest -q runs the Python test suite.
  • uv run recaf-mcp-bridge --stdio starts the development stdio server.

Python 3.11 or newer is required. Do not hand-edit uv.lock; update it through uv.

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.
