An agent skill that stress-tests technical plans before you build them.
Models are lazy about verification. They'll write a plan that says "use SQLite for concurrent writes" or "Y.js supports persistence out of the box" and move on without checking. These unchecked assumptions become mid-build surprises that force architectural pivots, messy workarounds, and wasted context.
This skill forces the model to actually verify its claims — searching real docs, ranking evidence quality, running proof-of-concept code when search is not enough, and fixing the plan before implementation starts. Each verification runs in a fresh sub-agent context, so there's less confirmation bias from the planning conversation — fewer hidden assumptions, less mid-build churn, and a clearer line between what's confirmed and what's still risk.
A plan claimed bash + sqlite3 would be fast enough for git hooks. The skill spun up parallel agents to research alternatives and run an actual latency POC:

The POC disproved the assumption — bash was 4-5x slower than estimated — and surfaced the real tradeoffs across runtimes:
