Saas Replacement Planner

name: saas-replacement-planner
description: Evaluates which SaaS tools can be replaced with AI agents. Takes a list of current SaaS subscriptions with costs, assesses replacement feasibility, estimates build vs buy economics, identifies Claude+MCP alternatives, and generates a comprehensive replacement plan with priority matrix, ROI analysis, implementation timeline, and risk assessment.

# SaaS Replacement Planner

Evaluate a company's SaaS stack and produce a rigorous, actionable plan that quantifies the ROI of migrating from subscription software to AI-agent-powered alternatives. Bias toward replacement where the economics support it, but stay honest: not every tool can be replaced today.

## Contents

- `references/analysis-framework.md` -- the six-step per-tool analysis (classification, feasibility tiers, build-cost formulas, Claude+MCP architecture, risk scoring, priority matrix)
- `references/output-template.md` -- full `saas-replacement-plan.md` document structure
- `references/patterns.md` -- proven replacement patterns by category and edge-case handling
- `references/analysis-guidelines.md` -- estimation rigor, honesty rules, OneWave AI thesis, and output quality standards

## Workflow

1. **Gather input.** Collect the SaaS tool list. Parse screenshots, CSVs, or bank statements; organize informal lists into a structured format (tool, monthly/annual cost, seats, primary use case). Ask clarifying questions only when critical data is missing: seat counts, primary workflows, integration dependencies, mission-critical vs nice-to-have, and compliance requirements.
2. **Research current pricing.** For each tool, verify pricing with WebSearch when numbers are missing or look off. Check per-seat pricing, outdated plans, API access for the replacement, and data export capability.
3. **Analyze each tool.** Run the complete six-step framework in `references/analysis-framework.md` for every tool. Do not skip tools or give superficial analysis. Apply matching patterns from `references/patterns.md`.
4. **Build the priority matrix.** Plot all tools on the Impact vs Effort axes. Sequence replacements and group tools that share infrastructure (e.g., all needing Supabase) to reduce incremental build cost.
5. **Generate the timeline.** Create a realistic timeline accounting for engineering capacity, parallel running periods, dependencies between replacements, and quick wins that fund later investments.
6. **Write the plan.** Generate `saas-replacement-plan.md` in the current working directory using the structure in `references/output-template.md`. Follow the rigor and quality standards in `references/analysis-guidelines.md`.
7. **Present key findings.** After writing the file, summarize total potential savings, the top 3 quick wins, any surprising findings, and the recommended first action.

## Core Principle

Every SaaS subscription is a recurring tax on the business; every agent replacement is an investment in owned infrastructure that compounds over time. Make the numbers speak clearly and let the ROI make the argument. See `references/analysis-guidelines.md` for the full OneWave AI thesis and how to frame the analysis.
