brainblast-oracle

brainblast-oracle is a command for coding agents from DSB-117/brainblast. It costs 0 tokens per session (387 once invoked), scanned A, original, MIT.

A command that checks whether a blockchain price feed was updated recently. It compares the feed account’s latest transaction slot with the current slot and reports whether the feed is fresh, stale, or has no history.

In plain words
What is it for?
Use it to check Pyth, Switchboard, Chainlink, or other account-based feeds, set staleness limits, request JSON output, and save a freshness report.
Why use it?
It helps prevent trading or protocol decisions based on an old price. Its exit status can be used as a safety check before a trade.

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-oracle 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 5d 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-oracle

Live On-Chain Intelligence: is the oracle fresh? Before you price anything against a Pyth / Switchboard / Chainlink feed, check when its account was last written.

Provider-agnostic — instead of parsing each oracle's binary layout, it measures the one universal signal: the slot of the most recent transaction touching the account vs. the current slot. A feed that hasn't updated recently is exactly how protocols get drained at the wrong price.

Usage

/brainblast-oracle <account> [--rpc URL] [--max-staleness-slots N | --max-staleness-seconds N] [--json]
npx brainblast oracle $ARGUMENTS
  • --rpc URL — use your own endpoint (the public RPC is rate-limited; pass Helius/Triton for reliable results).
  • --max-staleness-slots N — staleness threshold in slots (default 150 ≈ 60s).
  • --max-staleness-seconds N — threshold in seconds (converted at ~400ms/slot).
  • --json — machine-readable result for an agent.

Reports FRESH / STALE / NO_HISTORY with how many slots/seconds ago the feed last updated. Exit 1 on STALE or NO_HISTORY — wire it into a pre-trade gate. A markdown report is written to .agent-research/oracle-freshness.md.

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.
