One skill (@fde) routes by situation - you never pick a method by name. Three layers:
- Daily - prep, debrief, receipts, status, triage / doctor
- Engagement - land → discover → plan → build → ship → close (the methods below)
- Overlays - ai / fintech / healthcare / gov / artifacts (plus eval-pack as an AI companion)
The full map is below; per-method details live in skills-reference.md.
| Domain | Skills | What it covers |
|---|---|---|
| Embed & Trust | land, audit, stakeholder-radar, trust-engineering, scope-defense | First days: access, credibility, scope |
| Discover & Diagnose | discover, assumption-audit, use-case-scoring, sketch | Finding the real problem behind the brief |
| Plan & Align | plan, business-case, options-analysis, initiative-triage | Sequencing work, getting sponsor alignment |
| Build & Guard | build, incremental-build, test-on-legacy, blast-radius, debug, rescue, security-audit, observability | Building safely on their codebase |
| Ship & Verify | ship, review, rollback-drill, qa-live | Getting to production without surprises |
| Operate & Close | status, demo-prep, debrief, exec-narrative, dashboard, multi-customer-ops, close, handoff-engineering, pattern-extract, red-team, ingest, ingest-connect | Running and ending the engagement well; pulling from source MCPs |
Each skill is a method, not advice: the thinking the agent does, the artifact it drafts into .fde/ under ~/fde-engagements/, and the checkpoint with the human FDE.
Field judgment (blended into methods, not separate skills): land/discover use brief interrogation when the brief is thin; @fde enforces anti-invention gates; ship/red-team run a pre-blast challenge before irreversible moves.
Overlays layer domain judgment onto whatever skill is running - the agent activates them when your engagement involves the signal, without being told:
| Overlay | Triggers on | What it adds |
|---|---|---|
| ai | AI, ML, LLM, model, embeddings, RAG, agents | Model selection, RAG architecture, agent safety, drift monitoring, cost management |
| artifacts | deck, slides, report, governance, compliance pack, ADR | Executive decks, governance frameworks, ADRs, value reports |
| fintech | payments, PCI-DSS, cardholder data, anything that moves money | Idempotency, transaction integrity, fraud signals, silent-failure prevention |
| healthcare | PHI, HIPAA, EHR, patient data | De-identification, minimum-necessary, audit trails |
| gov | FedRAMP, ATO, CUI, classified | Authority boundaries, CUI marking, continuous monitoring |
AI companion (not a sixth overlay): eval-pack - engagement golden set / SHIP gate (evals.md). Loaded with the ai overlay when models are in scope.
