fde-os

The operating system for Forward Deployed Engineers. 34 skills across 6 domains — from first meeting to final handoff. Tell it your situation, it routes to the right skill, does the work, and the engagement memory writes itself.

Taking over mid-engagement. Reads what exists, separates what works from what was assumed.

Safe implementation in any codebase. Characterisation tests first, Strangler Fig for fragile code.

End of engagement. Retrospective, pattern extraction, clean handoff so the team can sustain it.

Generate a status dashboard across all active engagements from .fde/ data.

Systematic debugging. Reproduce first, isolate second, fix third. Never guess.

Find the real problem. Map the codebase. The brief is a hypothesis until evidence confirms it.

End-to-end agentic engineering on client engagements. Small tasks, source-first context, build, cleanup, review-fix loop, verify. Use when shipping code solo on an FDE project.

First 48 hours. Build trust, map stakeholders, define success before any work starts.

Break work into atomic tasks. Sequence by risk. Add stakeholder touchpoints every 2-3 tasks.

Production fire or crisis. Stabilise first, understand second, fix third.

Two-stage code review: did we build what was agreed, then is it safe to ship.

Deploy to production safely. Pre-flight checklist, canary deploy, verified rollback. No surprises.

Validate direction before committing. Prototype fast, show it, pitch the outcome.

FDEOS overlay for fintech. PCI-DSS, transaction integrity, idempotency, fraud signals.

FDEOS overlay for government. FedRAMP, ATO, data sovereignty, security controls, clearance.

FDEOS overlay for healthcare. HIPAA, PHI handling, audit trails, break-glass, AI policy.
