Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00024 | $0.00465 |
| Opus 5 | $0.00012 | $0.00233 |
| Sonnet 5 | $0.00005 | $0.00093 |
| Haiku 4.5 | $0.00002 | $0.00047 |
Grade A, and why
bpx-metadata 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 7d 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
metadata
PREREQUISITE: Read bpx-shared.
Usage
bpx metadata <file.uasset> --export <n>
bpx metadata set-root <file.uasset> --export <n> --key <k> --value <v> [--dry-run] [--backup]
bpx metadata set-object <file.uasset> --export <n> --import <i> --key <k> --value <v> [--dry-run] [--backup]
Behavior
- Default form reads one metadata export by --export index.
set-root: updates root metadata key/value.set-object: updates metadata for one import key/value.- Set commands report the resolved property path that was mutated.
[!CAUTION] This command includes write-capable operations. Confirm intent and run
--dry-runfirst.
Command Matrix
| Command | Use when | Notable defaults |
|---|---|---|
metadata |
Default form reads one metadata export by --export index. | Check bpx help for exact required flags. |
set-root |
updates root metadata key/value. | Check bpx help for exact required flags. |
set-object |
updates metadata for one import key/value. | Check bpx help for exact required flags. |
Code-Aligned Caveats
- There is no
metadata readsubcommand; read form isbpx metadata <file> --export <n>. - Object metadata updates require a valid
--importtarget.
High-Signal Examples
bpx metadata ./Sample.uasset --export 1
bpx metadata set-root ./Sample.uasset --export 1 --key SampleKey --value SampleValue [--dry-run] [--backup]
bpx metadata set-object ./Sample.uasset --export 1 --import 1 --key SampleKey --value SampleValue [--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.

bpx-metadata is a skill published in the GitHub repository wilddogjp/openbpx (99 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 24 tokens to every session and 465 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
playtest-report
Generates a structured playtest report template or analyzes existing playtest notes into a structured format. Use this to standardize playtest feedback collection and analysis.
unity-manual-component
Manually add, configure, reorder, and copy components on GameObjects using Unity Editor UI. For one-off Inspector workflows that do not need REST automation.
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
