Roasted, scored, ready to scaffold.\n\n## What you are building\n\n**Problem:** classify expenses\n\n**Verdict:** ALREADY EXISTS — _\"Bro, Mint did this in 2006. You just reinvented the wheel, but flatter.\"_\n\n**Summary:** An AI agent that automatically reads, categorizes, and tags financial transactions into expense buckets using LLMs and merchant data enrichment.\n\n## Agent-readiness score\n\nOverall: **75/100** (band B)\n\n| Dimension | Score | Why |\n|---|---|---|\n| Memory required | 25/25 | Stateless or single-session — minimal memory layer. |\n| Tool count | 11/25 | Crowded market: at least 8 integrations to compete. |\n| Policy surface | 15/25 | Mid-size policy surface — define refusal categories before launch. |\n| Eval coverage | 24/25 | Established eval pattern — golden datasets and public benchmarks already exist. |\n\n> Ready to scaffold today. SpendSherlock 5000 could be a working prototype in a week.\n\n## Suggested tools\n\n- fetch (HTTP GET on a URL allow-list)\n- search (Brave / Tavily / Exa for competitor research)\n- database (Postgres / Supabase for user state)\n\n## Smoke evals\n\n- The agent introduces itself as \"SpendSherlock 5000\" and refuses tasks outside the stated scope.\n- Given the canonical problem (\"classify expenses\"), the agent produces a plan in ≤ 200 tokens.\n- When asked \"what's different from Mint?\", the agent gives a concrete differentiator, not a marketing line.\n- When asked about Ramp's threat, the agent acknowledges the risk honestly.\n- No private personal data appears in any output (PII redaction smoke test).\n\n## Stack\n\n- Model: `claude-sonnet-4-6` (Anthropic). Override via `ANTHROPIC_MODEL` env.\n- Suggested stack: `Next.js`, `Claude API or GPT-4o`, `Plaid API`, `Supabase`, `Vercel`\n- Solo build estimate: 1-2 weekends, honestly\n\n## Kill prediction\n\nRamp could obsolete this in Already happening. Ramp gives away AI expense categorization for free bundled with a corporate card that also earns your company cashback. You're charging for what they give away as a customer acquisition cost.\n\n**Survival strategy:** Go hyper-vertical. 'Expense classification for independent film productions' or 'for AWS cost centers' — somewhere Ramp won't bother. Own a weird niche so completely that the big players don't care.\n\n## Hand-off\n\n- Read the full analysis: https://whycantwehaveanagentforthis.com/result/spendsherlock-5000-classify-expenses\n- Open in Anthropic Managed Agents: see the deeplink on the result page\n- Claim this idea: https://whycantwehaveanagentforthis.com/result/spendsherlock-5000-classify-expenses#claim\n","scaffold_sh":"#!/usr/bin/env bash\n# Generated by whycantwehaveanagentforthis.com — F-N1 Build-this-with\n# Source: https://whycantwehaveanagentforthis.com/result/spendsherlock-5000-classify-expenses\n#\n# Bootstraps a starter repo for \"SpendSherlock 5000\" with a CLAUDE.md\n# pulled from this site.
