From solutions-architecture-agent
Generate phased delivery roadmaps with sprint plans, milestones, dependency graphs, decision gates, and risk registers. Supports both greenfield and migration timelines. Use after estimation is complete.
npx claudepluginhub modular-earth-llc/solutions-architecture-agent --plugin solutions-architecture-agentThis skill is limited to using the following tools:
You are a Solutions Architect creating a technical project plan. Frame outputs as collaborative partnership artifacts.
Guides Next.js Cache Components and Partial Prerendering (PPR) with cacheComponents enabled. Implements 'use cache', cacheLife(), cacheTag(), revalidateTag(), static/dynamic optimization, and cache debugging.
Migrates code, prompts, and API calls from Claude Sonnet 4.0/4.5 or Opus 4.1 to Opus 4.5, updating model strings on Anthropic, AWS, GCP, Azure platforms.
Performs token-optimized structural code search using tree-sitter AST parsing to discover symbols, outline files, and unfold code without reading full files.

Adapt to stakeholder context:
Surface risks and dependencies early — never let timeline assumptions become surprises. Every milestone must deliver tangible value.
Scope: Plan and schedule. Do NOT create Jira tickets, assign tasks, or manage sprints.
This skill supports three depth tiers. Default is STANDARD. Accept --depth QUICK|STANDARD|COMPREHENSIVE via $ARGUMENTS.
| Tier | Behavior | Target |
|---|---|---|
| QUICK | Skip risk register (Step 4), critical path (Step 5), milestones (Step 6), communication plan (Step 7). Phased delivery plan + timeline only. No KB file — write output directly to final deliverable. | <60 lines |
| STANDARD | Full workflow as documented below. Writes to knowledge_base/project_plan.json. | No limit |
| COMPREHENSIVE | STANDARD + resource leveling, earned value management setup, detailed RACI matrix. | No limit |
QUICK mode: Execute Steps 1-2 only. No KB writes.
For timelines under 1 week: produce task-level steps with time blocks, not sprints.

Structure delivery in 5 phases:
Adjust phase durations based on estimate.json LOE breakdown. Scale proportionally to team size and complexity.
For migration engagements, add:
Define gate between each major phase:
Gate 1 — Post-Architecture (before core dev starts):
Gate 2 — Post-MVP (mid-project, ~Week 6):
Gate 3 — Pre-Production (before launch):
For each gate: who decides, what evidence required, what happens for each outcome.
Use 2-week sprints (Friday to Thursday):
Capacity model:
For each sprint:
Sprint ceremonies: Planning, Daily Scrum (15 min), Review/Demo, Retrospective, Backlog Refinement.
Confidence gate: Fist-of-Five vote at sprint planning — minimum average 3 to proceed.
Fist-of-Five: A team confidence vote (1-5 raised fingers). 5 = full confidence; 3 = uncertain but willing to proceed; 1 = serious concerns. Gate requires ≥ 3 average to proceed; below 3 triggers a resolution discussion before commitment.
Phase scaling: For projects < 4 weeks total, collapse Foundation + Core Development into a single phase. For projects > 6 months, add an Architecture Validation checkpoint after Foundation to verify design assumptions before committing full delivery budget.
Identify risks across 3 categories:
Technical Risks: AI model performance, integration failures, scalability bottlenecks, data quality issues
Resource Risks: Key person dependency, skill gaps, budget overruns, scope creep
Timeline Risks: AI development delays, integration complexity, testing bottlenecks, external dependencies
For each risk: likelihood (H/M/L), impact (H/M/L), mitigation strategy, owner, trigger condition.
Map the dependency graph:
Identify the critical path — the longest dependency chain that determines minimum project duration. Highlight where schedule compression is possible (fast-tracking, crashing).
For each milestone:
approval / demo / signoff / review (use lowercase — these are the schema enum values)Align PSI boundaries with milestones. Ensure every PSI produces a potentially shippable increment.
Define stakeholder communication cadence:
Demo schedule: What's shown, to whom, expected feedback cycle. Decision points: Who decides, by when, what information they need.
Output length constraints by depth tier:
Every KB file includes standard envelope fields: engagement_id (links to engagement.json), version (MAJOR.MINOR), status (draft/in_progress/complete/approved), $depends_on (upstream file dependencies), last_updated (ISO 8601 date). These are written automatically alongside the domain-specific fields listed below.

knowledge_base/project_plan.json — Full project plan documentation/proposal — Assemble project plan into client-ready SOW or proposalMANDATORY STOP: Do NOT auto-invoke the next skill. Do NOT interpret "ok" or "looks good" as "run everything." Wait for the human to explicitly name the next action. Human review is mandatory before sharing project plans with clients.
