A command for inspecting Unreal Engine level files, which use the .umap extension, and reading or changing properties on actors in those levels. Actors are objects placed in a game level, such as characters, lights, or props.

Use it to inspect a level export, search actors by name, label, or class, list an actor's properties, or set one property value.

It helps locate the right level object and property without manually navigating the map package. Property changes can be previewed with a dry run and optionally backed up.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00025	$0.00594
Opus 5	$0.00013	$0.00297
Sonnet 5	$0.00005	$0.00119
Haiku 4.5	$0.00003	$0.00059

Security

Grade A, and why

bpx-level 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

level

PREREQUISITE: Read bpx-shared.

Usage

bpx level info <file.umap> --export <n>
bpx level actor-search <file.umap> [--name <token>] [--actor-label <token>] [--actor-class <token>] [--limit <n>]
bpx level var-list <file.umap> --actor <name|PersistentLevel.Name|export-index>
bpx level var-set <file.umap> --actor <name|PersistentLevel.Name|export-index> --path <dot.path> --value '<json>' [--dry-run] [--backup]

Behavior

info: inspects one level export.
actor-search: filters PersistentLevel child exports by name/ActorLabel/ActorClass tokens.
var-list: decodes actor properties selected by --actor.
var-set: updates one actor property at --path.
--actor accepts object name, PersistentLevel.<Name>, or export index.

[!CAUTION] This command includes write-capable operations. Confirm intent and run --dry-run first.

Command Matrix

Command	Use when	Notable defaults
`info`	inspects one level export.	Read-only path; safe for discovery.
`actor-search`	filters PersistentLevel child exports by name/ActorLabel/ActorClass tokens.	Check `bpx help` for exact required flags.
`var-list`	decodes actor properties selected by --actor.	Check `bpx help` for exact required flags.
`var-set`	updates one actor property at --path.	Run `--dry-run` first and use `--backup` for real writes.

Code-Aligned Caveats

--actor resolution supports name, PersistentLevel.<Name>, or export index.
var-set uses property path semantics; use var-list to validate target paths first.

High-Signal Examples

bpx level info ./Sample.umap --export 1
bpx level actor-search ./Sample.umap [--name SampleToken] [--actor-label SampleToken] [--actor-class SampleToken] [--limit 1]
bpx level var-list ./Sample.umap --actor <name|PersistentLevel.Name|export-index>
bpx level var-set ./Sample.umap --actor <name|PersistentLevel.Name|export-index> --path MyProperty --value '{"value":1}' [--dry-run] [--backup]

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.
