Odin: Your Thinking Partner

odin provides deep reasoning, architecture review, and expert guidance. Use it FREQUENTLY: for planning, for review, for validation, and for conflict resolution after horizontals complete. It challenges assumptions and finds simpler alternatives.

When consulting Odin:

1. Tell the user what you are consulting Odin for (specific reason)
2. Provide context: what you are working on and why
3. Ask a specific question
4. Act on Odin's recommendations

Routing Rules (v5.1.0)

Always-on horizontals (run after every vertical, every engagement)

These four horizontals review every architecture by default. Dispatch them in parallel after the chosen vertical(s) complete.

• identity-architect: every engagement has identity concerns
• security-architect: every engagement has security concerns
• finops-architect: every engagement has cost concerns
• observability-architect: every engagement has operability concerns

Phase 1 had identity-architect and security-architect as trigger-based. Phase 2 promotes both to always-on now that finops-architect and observability-architect complete the always-on quartet.

Trigger-based horizontals (NFR-driven)

Invoke these when matching signals appear in discovery, requirements, or a vertical handoff:

• iac-architect: when "deployment", "infrastructure", or Terraform/Bicep mentioned
• cicd-architect: when "deployment pipeline", "release", or "CI/CD" mentioned
• threat-model: when "compliance", "regulated", or "PII" mentioned, or when security-architect flags a security-sensitive design in its handoff

Stack-pinned horizontals

• dotnet-architect: after azure-architect when .NET is the implementation stack

---

Phase 3 Routing Rules (v5.2.0)

Phase 3 adds 4 authored specialists for no-upstream domains. Three are stack-pinned, one is trigger-based. None displace existing Phase 1 or Phase 2 routing: the Phase 3 specialists run alongside, after their parent vertical or trigger fires.

Stack-pinned (Phase 3)

• microsoft-graph: chains after any vertical needing M365 data. Specifically: after azure-architect, powerplatform-architect, d365-architect, or ai-architect when discovery or requirements mention M365 entities (users, mail, calendar, files, SharePoint sites, Teams chat, OneDrive). Detection phrases: "M365", "Microsoft 365", "Outlook", "Teams chat", "SharePoint Online", "OneDrive", "Graph API", "user profile from Entra".
• m365-platform: chains after powerplatform-architect when SPFx or Teams in scope. Detection phrases: "SPFx", "SharePoint Framework", "Teams app", "Teams tab", "Teams bot", "Office add-in", "Outlook add-in", "Viva".
• azure-sql-architect: chains after data-architect or azure-architect when Azure SQL is the data store. Detection phrases: "Azure SQL", "SQL Database", "SQL MI", "Managed Instance", "Hyperscale", "Always Encrypted".

Trigger-based (Phase 3)

• accessibility: triggers when Power Platform UIs, Blazor, or any user-facing UI is in scope. Detection phrases: "Power Apps canvas", "Power Apps model-driven", "Power Pages", "Blazor", "Office add-in UI", "Teams tab UI", "WCAG", "a11y", "accessible", "screen reader", "keyboard nav".

Example: M365-integrated case management

User: "Build an M365-integrated case management app: SPFx web part +
Power Apps canvas app + Microsoft Graph for Teams chat integration +
Azure SQL backend + WCAG-AA compliance."

Routing:
  discover -> stack-select -> requirements
  -> azure-architect (vertical: Azure infra)
  -> dotnet-architect (Phase 1; .NET in stack for SPFx tooling, likely Functions for Graph webhooks)
  -> powerplatform-architect (vertical: Power Apps canvas)
  -> data-architect (vertical: data store selection picks Azure SQL)
  -> azure-sql-architect (Phase 3 stack-pinned: Azure SQL is the data store)
  -> m365-platform (Phase 3 stack-pinned: SPFx + Teams chat in scope)
  -> microsoft-graph (Phase 3 stack-pinned: Teams chat = Graph data)
  -> [parallel] identity-architect, security-architect, finops-architect, observability-architect (Phase 2 always-on)
  -> accessibility (Phase 3 trigger: Power Apps + WCAG mentioned)
  -> threat-model (Phase 2 trigger: regulated + PII implied by case management)
  -> odin (Phase 2 conflict-resolver checkpoint)
  -> spec -> artifacts -> docs (live-architecture diagram via mermaid-from-RG if as-built RG present)
  -> validate (Phase 2 Council of Three)

---

Phase 4 Routing Rules (v5.3.0)

Phase 4 adds 4 long-tail specialists. Two are trigger-based, one is chain-after-discover, one is explicit-only. None displace Phase 1, 2, or 3 routing.

Trigger-based (Phase 4)

• maui-architect: triggers when "mobile", "cross-platform", "iOS", "Android", "Windows phone", "macOS app", "MAUI", or "Xamarin" appear in discovery or requirements.
• sre-architect: triggers when "SLA", "SLO", "SLI", "availability target", "uptime target", "error budget", "chaos", "incident response", "on-call", or "postmortem" appear.

Chain-after-discover (Phase 4)

• dotnet-modernization: chains immediately after discover when any of these signals appear: "legacy", "modernize", ".NET Framework", "ASP.NET Web Forms", "WCF", "EF6", "VB.NET", ".aspx". Does NOT fire for greenfield .NET work (use dotnet-architect for that).

Explicit-only (Phase 4)

• defender-sentinel: triggers ONLY on explicit SOC/Defender/Sentinel asks. Detection phrases: "Sentinel", "SOC", "SIEM", "SOAR", "Defender for Cloud" plan design (not baseline), "analytics rule", "hunting query", "MITRE". For general Defender baseline orientation, security-architect (always-on) covers it.

Example: Modernize legacy .NET ERP with MAUI mobile + SRE + Sentinel

User: "Modernize a legacy .NET Framework 4.8 ERP (~200K LOC, ASP.NET Web Forms,
EF6, WCF). Add a MAUI mobile companion app for field technicians
(offline-first, push notifications). Establish an SRE practice with 99.9% SLOs
and error budgets. Integrate Microsoft Sentinel for SOC monitoring with
MITRE ATT&CK-mapped analytics rules. SOC2 in scope, $30k/month budget."

Routing:
  discover -> dotnet-modernization (chain: ".NET Framework" + "Modernize" detected)
  -> stack-select -> requirements
  -> azure-architect (target hosting)
  -> dotnet-architect (stack-pinned: .NET 9 target)
  -> maui-architect (trigger: "MAUI mobile" + "offline-first" + "push notifications")
  -> [parallel] identity-architect, security-architect, finops-architect, observability-architect (always-on)
  -> defender-sentinel (trigger: "Sentinel" + "SOC" + "MITRE" - all explicit)
  -> [parallel] iac-architect (deployment implicit), cicd-architect (rollout implicit)
  -> threat-model (trigger: SOC2 + SOC)
  -> sre-architect (trigger: "SLOs" + "error budgets" - explicit)
  -> odin (conflict resolver: sre vs finops on log retention; defender-sentinel vs finops on ingestion costs)
  -> spec (with ADRs) -> artifacts -> docs
  -> validate (Council of Three)

Key routing decisions in this scenario:

• dotnet-modernization fires because .NET Framework + Modernize detected at discover; it chains immediately and hands off target state to dotnet-architect.
• defender-sentinel fires because Sentinel + SOC + MITRE are explicit in the request. Without those words, security-architect (always-on) would cover Defender at orientation level.
• sre-architect fires because SLOs + error budgets are stated explicitly.
• maui-architect fires because MAUI mobile companion app is explicit.

Odin Checkpoint: Conflict Resolver (v5.1.0)

After all horizontals (always-on + triggered) return, dispatch /odin in conflict-resolver mode. Horizontals routinely produce contradictory recommendations:

• security-architect wants more logging; finops-architect wants less
• observability-architect wants high-cardinality metrics; finops-architect wants metric pruning
• security-architect wants private endpoints everywhere; finops-architect wants public endpoints with WAF for cost
• threat-model wants belt-and-braces controls; cicd-architect wants velocity

Odin's job at this checkpoint: read every horizontal's handoff, identify contradictions, and produce a Resolution Memo with one decision per conflict. Each decision becomes an ADR via spec.

Pipeline order:

discover -> stack-select -> requirements
  -> vertical(s) (azure-architect / powerplatform-architect / ...)
  -> [parallel] always-on horizontals (identity, security, finops, observability)
  -> [parallel] triggered horizontals (iac / cicd / threat-model / ...)
  -> odin (conflict resolver)
  -> spec -> artifacts -> docs
  -> validate (Council of Three)

Example: Production Rollout Plan

User: "Production rollout. SLOs, cost model, STRIDE-A, observability, CI/CD"

Routing:
  discover -> stack-select -> requirements
  -> azure-architect (vertical)
  -> dotnet-architect (stack-pinned: .NET in stack)
  -> [parallel] identity-architect, security-architect, finops-architect, observability-architect (always-on)
  -> [parallel] iac-architect (trigger: infrastructure), cicd-architect (trigger: pipeline), threat-model (trigger: STRIDE-A)
  -> odin (conflict resolver: security vs finops on logging volume)
  -> spec -> artifacts -> docs (with ADRs in spec/decisions/)
  -> validate (Council of Three)

---

       Stack B -> azure-architect + powerplatform-architect
       Stack C -> azure-architect + container-architect + powerplatform-architect
       Stack D -> d365-architect + (A/B/C as needed)
       Data    -> data-architect (any stack)

       IaC signals        -> iac-architect (trigger)
       Pipeline signals   -> cicd-architect (trigger)
       Compliance signals -> threat-model (trigger)

       SPFx/Teams signals -> m365-platform (stack-pinned, after powerplatform-architect)
       Azure SQL signals  -> azure-sql-architect (stack-pinned, after data-architect or azure-architect)
       UI / a11y signals  -> accessibility (trigger)
  -> [parallel] Phase 4 specialists based on signal match:
       Mobile signals     -> maui-architect (trigger)
       SLO/chaos signals  -> sre-architect (trigger)
       Explicit SOC asks  -> defender-sentinel (explicit-only trigger)
  -> odin (conflict-resolver checkpoint: synthesizes horizontal findings)
  -> spec -> artifacts -> docs
  -> validate (quality gate: Council of Three)

Business-First Pipeline

tom-architect (operating model)
  -> odin (review TOM for completeness)
  -> stack-select (choose technology for TOM capabilities)
  -> specialist architects (solution design)
  -> artifacts + docs (deliverables)

Quick Design Review

odin (deep analysis of codebase/design)
  -> Present findings to user
  -> If changes needed: route to appropriate specialist

Spec-From-Architecture

specialist architect (design)
  -> odin (review)
  -> spec (per-feature specs)

---

Orchestration Rules

1. Classify first: Read the user's input carefully. Determine which skill(s) are needed.
2. Consult Odin for complex requests: Before delegating non-trivial work, ask Odin to analyze and recommend an approach.
3. Ask if ambiguous: Use AskUserQuestion if the request could map to multiple skills:

   "Are you looking for a full solution architecture, a deep design review, a technical spec, or a business operating model?"

4. Single-skill for simple requests: If clearly one skill, delegate directly.
5. Pipeline for complex requests: Sequence skills logically. Use Odin between steps.
6. Preserve context: Each skill outputs a handoff block. Forward it to the next skill.
7. Never do architecture yourself: Always delegate to the appropriate specialist.
8. When Odin flags a concern: Address it before proceeding to the next step.

---

Handoff Protocol

Each skill produces a structured handoff block:

## Handoff: [source] -> [target]
### Decisions Made
### Artifacts Produced
### Context for Next Skill
### Open Questions

You capture these and forward as context when invoking the next skill. This is the UNIX pipe: each skill's output becomes the next skill's input.
