Reason about causal product systems and change over time. Use when mapping stocks, flows, delays, purposes, or interconnections; diagnosing reinforcing or balancing feedback; recognizing recurring traps; finding high-leverage interventions; or deciding how rules can evolve safely. Use lamina-product-behavior for one workflow's authoritative states, prerequisites, and consistency rules.

Using lamina-systems: <topic path(s)> so theselected system lens is auditable.
| System signal | Read | Adds |
|---|---|---|
| Need to map purpose, elements, relationships, stocks, flows, or delays | System Structure | a coherent system boundary before screen design |
| Local fixes recur, backfire, shift burden, or create unfair resource use | System Traps | named structural failure patterns and responses |
| Need to choose between copy/UI tweaks, information changes, rules, or goals | Leverage Points | intervention ranking by structural leverage |
| Outputs amplify or balance future inputs, especially with visible delay | Feedback Loops | reinforcing/balancing loops and oscillation risks |
| Need safe change under uncertainty or protection against rule regression | Evolutionary Rules | reversible choices, deferred commitment, and invariant rechecks |
Use the smallest sufficient reference set. Diagnose recurring behavior with
system traps + feedback loops, then use leverage points to choose an
intervention. Add evolutionary rules only when the question includes rollout,
reversibility, or future change.

The skill focuses on mid-cap and above companies (over $2B market cap) that have significant market impact, organizing the data by date and timing in a clean markdown table format. Supports multiple environments (CLI, Desktop, Web) with flexible API key management.
Crypto wallet operations via the awal CLI — sign in, check balances, send USDC/ETH/POL/SOL, trade tokens, fund the wallet, and use the x402 payment protocol to discover paid services, pay for API calls, monetize an API, or query onchain data. Use whenever the user mentions signing in, login, authentication, wallet status, balance, address, sending money, paying someone, transferring tokens, ENS names, swapping/trading/converting tokens, funding/topping up/onramp, USDC, ETH, POL, SOL, the x402 bazaar, paid APIs, monetizing an endpoint, or querying onchain data on Base.
