brainblast-fee-configs

brainblast-fee-configs is a command for Claude Code from DSB-117/brainblast. It costs 0 tokens per session (309 once invoked), scanned A, original, MIT.

A catalogue of configuration mistakes that can silently produce zero fees, royalties, or rewards even though a transaction succeeds. It also identifies available checks for detecting some of these mistakes.

In plain words
What is it for?
Use it to list or inspect fee-related checks for blockchain SDKs, including Metaplex royalty settings and some Token-2022 or reward configurations.
Why use it?
It helps find revenue settings that are missing or set to zero, so creators, treasuries, or token holders do not unknowingly collect nothing.

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

brainblast-fee-configs 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 8d 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

/brainblast-fee-configs

Fee Config Validator: the generalized Bags exploit. A curated catalog of the silent zero-revenue class — revenue-bearing config fields (fees, royalties, rewards) that, if omitted or set to zero, quietly collect nothing forever. The call succeeds, nothing reverts, and a creator/treasury/holder simply earns $0.

Each entry names the SDK, the exact field, what zero/omitted costs you, and — when one exists — the bundled brainblast rule that statically detects it. An integrity test guarantees every referenced rule actually exists.

Usage

/brainblast-fee-configs [id] [--json]
npx brainblast fee-configs $ARGUMENTS

Run with no argument to list the catalog (fees · royalties · rewards) with enforced/advisory status, or pass an id to see one in detail.

The companion static rule metaplex-seller-fee-zero (and the general fee-configs-zero-or-missing checker) fail a build when a Metaplex token is created with sellerFeeBasisPoints omitted or zero — creators earn no royalties on secondary sales. Catalog entries marked advisory have no bundled rule yet (e.g. Token-2022 transfer fee, generic reward rates) and are grep targets / project-local rule candidates.

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.
