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-write 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 4d 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

write

PREREQUISITE: Read bpx-shared.

Usage

bpx write <file.uasset> --out <new.uasset> [--dry-run] [--backup]

Behavior

  • Rewrites parsed package bytes to --out using current in-memory structure.
  • Never modifies the source file; output target is required.
  • --dry-run reports changed/bytes without writing files.
  • --backup creates <out>.backup when destination already exists.

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

High-Signal Examples

bpx write ./Sample.uasset --out ./Sample.out.uasset [--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.
