Tools and fixed-scope help

Three tools. One rule.

Keep the evidence inspectable: the state change behind a bug, the proof behind an accessibility finding, or the reachable content behind an MCP injection surface.

No invented AI certainty. No hidden subscription. No sales call required.

What stays honest.

  • Tools support professional judgment; they do not replace it.
  • Sensitive state and audit evidence get explicit local and redaction boundaries.
  • Fixed-scope services start only after inputs and deliverables are agreed in writing.
  • Current proof is public. Early user counts are not dressed up as product-market fit.

Bring one concrete problem.
