BPX blueprint command skill. An agent skill from wilddogjp/openbpx.

  • SKILL.md covers Usage, Behavior, Command Matrix and Recommended Workflow, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Bpx Blueprint is an agent skill from wilddogjp/openbpx. BPX blueprint command skill. Inspect and analyze blueprint exports, bytecode, and graph data.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: OpenBPX: Blueprint Toolkit for Unreal Engine. The licence is Apache-2.0.

Example prompts

  • “/bpx-blueprint”

What it can do on your machine

Read from SKILL.md and the folder at commit 1508eb3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Bpx Blueprint loads about 1.4k tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 444 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~27
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

bpx blueprint scan-functions <directory> --recursive [--name-like <regex>] [--aggregate]

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).

Command Matrix

CommandUse whenNotable defaults
infosummarizes blueprint/function exports.Read-only path; safe for discovery.
bytecodeextracts selected bytecode range as base64.Check bpx help for exact required flags.
disasmdisassembles bytecode (json|toml|text, optional analysis).Check bpx help for exact required flags.
tracetraces an execution path between nodes.Check bpx help for exact required flags.

infer-packemits CFG/callsite/def-use inference artifacts.Check bpx help for exact required flags.
scan-functionsaggregates function names across a directory.Check bpx help for exact required flags.
  • Start with bpx blueprint info to identify candidate exports and confirm whether you are dealing with a Blueprint asset, a WidgetBlueprint, or a generated class payload.
  • Use search to narrow by member, node, or symbol name before moving to heavier analysis commands.
  • Reach for trace and call-args when you already know the node or function you care about and want a focused dependency path.
  • Use disasm or bytecode only after you have identified the target export and execution slice; they are best for instruction-level inspection, not broad discovery.
  • Prefer refs when you need reverse lookup from a soft object path back to the Blueprint nodes/pins that mention it.
  • For WidgetBlueprint construction and edit workflows, switch to bpx-widget. Keep this skill focused on Blueprint analysis rather than widget tree authoring.

Worked Recipe

bash
bpx blueprint info ./Content/BP_Player.uasset
bpx blueprint search ./Content/BP_Player.uasset --member ApplyDamage --show name,class,member
bpx blueprint trace ./Content/BP_Player.uasset --from K2Node_CallFunction_12 --max-depth 6
bpx blueprint call-args ./Content/BP_Player.uasset --member ApplyDamage --all-pins
bpx blueprint disasm ./Content/BP_Player.uasset --export 21 --analysis --format text
  • This is the preferred shape for "find a Blueprint function, inspect the call path, then disassemble the final target export".
  • Use search and trace first so disasm stays focused on a specific export instead of becoming a broad dump.
  • If your goal is WidgetBlueprint construction or widget property mutation, use bpx-widget instead of treating this analysis recipe as an authoring workflow.

Code-Aligned Caveats

  • Large blueprints can produce very large payloads; constrain via --limit/--max-steps.
  • refs --include-routes can be expensive; disable routes when doing broad scans.
  • disasm --entrypoint implies analysis-oriented output.
  • trace and call-args are most useful after search or info has already narrowed the target export/node set.
  • For WidgetBlueprint edit flows and UE-openability caveats, prefer bpx-widget over embedding widget-authoring guidance here.

High-Signal Examples

bash
bpx blueprint info ./Content/BP_Player.uasset
bpx blueprint search ./Content/BP_Player.uasset --member ApplyDamage --show name,class,member
bpx blueprint trace ./Content/BP_Player.uasset --from K2Node_CallFunction_12 --max-depth 6
bpx blueprint disasm ./Content/BP_Player.uasset --export 21 --analysis --format text
