The open stack a Delta actually deploys.

Offline, dependency-free, CI-gated agent skills you can fork. The “paved superhighway” half of the model — so you’re not rebuilding evals, discovery, and scoring on every engagement. Every one ships a SKILL.md and, where it runs, a tested scripts/ core. Try three of them live in your browser →

The staffing brain — vet, match, plan.

Two agentic web apps you can open right now — no install, no login. The vetting scorecard is the eval-gate; the staffing brain wraps it into the full loop: connect demand to supply, gate every match on evidence, and recommend each person’s and each team’s next best step.

The evaluation spine

Know it works — to the operator, at 5pm.

Evaluation is the load-bearing skill of FDE work. These turn “does it work?” into a deterministic pass/fail with evidence — the gate that makes everything else trustworthy.

Discovery → architecture → integration

From a messy room to a shipped agent.

The FDE-craft half: walk into ambiguity, find the real problem and the real data, propose the smallest architecture that wins — and expose it as callable tools.

Compose

Skills are blocks; workflows chain them.

The first composition tool: an engagement go/no-go that runs two skills and AND-s their gates — because you must clear both failure modes, not one.

Author your own

Knowledge in, field kits out.

The meta-tools — compile a research vault into a navigable spine, and mint convention-correct Field Kits so your hard-won knowledge becomes a forkable asset.

All seven run offline and CI-gated — they work inside a customer perimeter with no network. Clone the repo and run the suite: for d in skills/*/tests; do python3 -m unittest discover -s "$d"; done.
