bpx-stringtable

A command-line tool for reading and changing StringTable entries in Unreal Engine asset files. A StringTable is a named collection of reusable text values, often used for game dialogue or translations.

In plain words
What is it for?
Use it to list StringTable exports, update or remove an existing key, or change a StringTable namespace in a .uasset file.
Why use it?
It avoids manually editing binary asset files and provides a dry-run option before changes are written.

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-stringtable 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 3d 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.

What it actually says

stringtable

PREREQUISITE: Read bpx-shared.

Usage

bpx stringtable read <file.uasset>
bpx stringtable write-entry <file.uasset> --export <n> --key <k> --value <v> [--dry-run] [--backup]
bpx stringtable remove-entry <file.uasset> --export <n> --key <k> [--dry-run] [--backup]
bpx stringtable set-namespace <file.uasset> --export <n> --namespace <ns> [--dry-run] [--backup]

Behavior

  • read: lists string table exports.
  • write-entry: updates an existing key value.
  • remove-entry: removes an existing key.
  • set-namespace: rewrites string table namespace.
  • Write commands operate on existing string table exports and report changed-byte status.

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

Command Matrix

Command Use when Notable defaults
read lists string table exports. Read-only path; safe for discovery.
write-entry updates an existing key value. Run --dry-run first and use --backup for real writes.
remove-entry removes an existing key. Check bpx help for exact required flags.
set-namespace rewrites string table namespace. Check bpx help for exact required flags.

High-Signal Examples

bpx stringtable read ./Sample.uasset
bpx stringtable write-entry ./Sample.uasset --export 1 --key SampleKey --value SampleValue [--dry-run] [--backup]
bpx stringtable remove-entry ./Sample.uasset --export 1 --key SampleKey [--dry-run] [--backup]
bpx stringtable set-namespace ./Sample.uasset --export 1 --namespace Game [--dry-run] [--backup]
Changes

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.
