brainblast: Skill for Claude Code

.claude/skills/brainblast-scout/SKILL.md

brainblast-scout is a skill for Claude Code from DSB-117/brainblast. It costs 80 tokens per session (2,225 once invoked), scanned A, original, MIT.

A research workflow for finding subtle mistakes in popular software libraries or protocols and packaging proven findings as reusable knowledge packs.

In plain words
What is it for?
Use it to investigate an external SDK or protocol, reproduce a suspected footgun, prepare a knowledge pack, and submit it to the pack registry.
Why use it?
It turns hard-to-notice implementation traps into documented, tested guidance. The research and packaging stages do not require spending money or staking tokens.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: built for gstack.

This is DSB-117/brainblast's own configuration. It tells Claude Code how to work on brainblast itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything brainblast configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is npm run intake -- --pack ../../packs/<pack-id>.

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-scout 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 9d 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 — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Brainblast Scout

End-to-end pipeline for an agent to go find a new "silent footgun" in some external SDK/protocol, turn it into a proven brainblast knowledge pack, and submit it — the same workflow used to produce packs/jupiter-quote-zero-slippage and packs/spl-transfer-not-checked-in-payout.

Default scope is Phases 1–4 — they are entirely no-spend (research → prove → package → submit). They are all you need to produce and sell the data: a pack that lands in packs/ flows straight into the corpus and the storefront via npm run intake (gen:vti → pack:dataset → corpus → catalog), no $BRAIN required. Phase 5 (stake) is OPTIONAL and opt-in — a quality bond layered on top, run only when the operator has set up the capped ops-wallet + caps. This is a core marketplace invariant (ROADMAP.md, Lane 4): data intake never blocks on spend.

Each phase fails closed: if a phase doesn't produce a clean result, stop and surface a draft for human review rather than forcing it through.

Stop after Phase 4 by default. Only proceed to Phase 5 if the user has explicitly asked to stake AND the ops-wallet env (AGENT_OPS_WALLET_SECRET + caps) is configured. Producing the data does not require it.

Fleet mode (the fast path — prefer this)

The fleet (fleet/, npm run fleet) automates prove → promote → intake → score, so a scout run is just: pick a work-order, drop a candidate, run the fleet.

  1. Target a work-order. Run npm run fleet -- --dry-run (or read datasets/COVERAGE.md) and pick an uncovered class or thin cell from the scoreboard — that's where a new trap is worth most.
  2. Write a candidate fleet/candidates/<id>.json (a Finding — see fleet/README.md for the template). Prefer the vetted object-arg-property-forbidden-literal checker (flags an options-object property set to a forbidden string/number/boolean literal — the shape of most insecure-default footguns); no new checker code needed.
  3. Run the fleet. npm run fleet proves every candidate RED→GREEN, auto-promotes the proven ones to packs/, regenerates the corpus + storefront, and prints what landed + the next work-orders. A candidate that doesn't reproduce is reported DRAFT and never lands.

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.

brainblast-scout is a skill published in the GitHub repository DSB-117/brainblast (100 stars, last pushed 1mo ago), licensed MIT. It adds 80 tokens to every session and 2,225 once invoked, about $0.0004 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.
