A procedure for producing a time-stamped token-risk report: classifying holder accounts (excluding pools/vaults/burn/vesting from raw wallet counts), measuring concentration and linked-wallet clusters with evidence and confidence rather than assertion, verifying liquidity custody and lock mechanisms on-chain (not by marketing claim), decoding authorities/extensions/trading restrictions, and issuing a scorecard that exposes reasons and data gaps instead of a…

DEX Fee, Slippage and Break-Even Guide. A procedure for calculating the true break-even price move on a DEX trade: defining consistent cash-flow units, modeling entry execution (route, fees, price impact, slippage, failed attempts) separately from a size-dependent exit ladder, solving for the exact break-even percentage that covers both legs, setting execution guardrails, and reconciling the realized wallet result against the model — because chart price movement alone doesn't account for…

NFT Authenticity and Spam Triage. A no-signature triage procedure for an unexpected NFT: recording the asset without clicking any link or signing anything, verifying on-chain collection/creator/update-authority identity against official sources (never against the NFT's own metadata), inspecting off-chain metadata URIs in isolation, and classifying the asset as verified authentic, likely spam/phishing, unverified, or program-specific before choosing a safe hide/burn/ignore action.

Drained-Wallet Incident Guide. An incident-response procedure for a suspected Solana wallet compromise: stopping interaction and preserving evidence before it's lost, distinguishing key/seed compromise from a single malicious approval, creating a verifiably clean new wallet on a clean device, inventorying and safely moving remaining assets with minimum signing, rotating related accounts, and permanently retiring the compromised address rather than reusing it once "quiet."

Agent Evaluation-Test Generator. A procedure for turning an agent specification into a real evaluation suite: translating vague requirements into observable, gradable claims (correct tool/arguments/outcome/refusal/budget), partitioning the case space into normal/boundary/adversarial/permission/cost cases, building safe sandboxed fixtures so evaluation can't cause real side effects, preferring deterministic state/tool-trace graders over LLM-judge-only scoring, running baseline vs candidate with…
