What you'd actually build.

Three real operational workflows, end to end: inputs, run trace, artifacts, receipt. Same runtime primitives across all three.

Security · Compliance

soc2-evidence

Collect quarterly SOC2 evidence: policy attestations, access reviews, ticket samples, vendor reports.

outcome → 3 minutes + one human approval. Receipt becomes the audit artifact.

finance-recon

Compare invoices against contracts, usage exports, and payments. Produce exception report + auditor-ready trace.

all three share

Same primitives. Different work.

Identity. Scoped grants. Sandboxed runtime. Workspace files. Approvals. Receipts. Replay. Each workflow above is @skill + runtime — no bespoke deployment pipeline, no shared credentials, no audit gap.
