bpx-blueprint

bpx-blueprint is a skill for Claude Code from wilddogjp/openbpx. It costs 27 tokens per session (1,484 once invoked), scanned A, original, Apache-2.0.

A command-line tool for inspecting Unreal Engine Blueprint files, which store visual game logic. It can examine their data, compiled instructions, connections, calls, references, and search results.

In plain words
What is it for?
Use it to inspect Blueprint packages, disassemble their instructions, trace node connections, find function arguments, search contents, and analyze references.
Why use it?
It helps developers understand what a Blueprint contains without opening it only through the game editor. It also supports tracing logic and investigating how assets are connected.

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is **PREREQUISITE:** Read [bpx-shared](../bpx-shared/SKILL.md)..

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

bpx-blueprint 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 10d 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.

Behavior

  • info: summarizes blueprint/function exports.
  • bytecode: extracts selected bytecode range as base64.
  • disasm: disassembles bytecode (json|toml|text, optional analysis).
  • trace: traces an execution path between nodes.
  • call-args: inspects call-node argument pins/defaults.
  • refs: reverse-searches soft-path usage on node pins.
  • search: token-searches nodes/pins in one blueprint package.
  • scan-functions: aggregates function names across a directory.
  • infer-pack: emits CFG/callsite/def-use inference artifacts.
  • bytecode/disasm support range selection (auto|export-map|ustruct-script|serial-full).

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.
