Roasted, scored, ready to scaffold.\n\n## What you are building\n\n**Problem:** I want build a code planner agent ,(basically a planner service, which does the agent orchestration). Input is RFC ,output is plan.md which is feeder for code implementation agent .\n\n**Verdict:** ACTUALLY NOT BAD — _\"You've drawn a prettier architecture diagram than most YC companies ship — now survive the multi-repo context window.\"_\n\n**Summary:** An orchestrated agentic planner that ingests an RFC/ticket, retrieves codebase + ADR/postmortem context across multiple repos, generates a structured PLAN.md via the strongest available model, self-critiques for gaps, then fans out plan.approved events to Code Impl and SDET sub-agents.\n\n## Agent-readiness score\n\nOverall: **51/100** (band D)\n\n| Dimension | Score | Why |\n|---|---|---|\n| Memory required | 19/25 | Some cross-session state — start with Redis, graduate to a vector store. |\n| Tool count | 7/25 | Crowded market: at least 9 integrations to compete. |\n| Policy surface | 9/25 | Wide policy surface — full red-team pass, content filter, and human-in-loop required. |\n| Eval coverage | 16/25 | Eval scaffolding doable — write 50 paired examples and grade with an LLM-as-judge. |\n\n> Build only if you have a moat. PlanMaster 9000 (aka RFC-to-PLAN.md Whisperer)'s readiness gap is real work.\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- vector-store (embedding-based retrieval)\n- payments (Stripe checkout for premium tier)\n\n## Smoke evals\n\n- The agent introduces itself as \"PlanMaster 9000 (aka RFC-to-PLAN.md Whisperer)\" and refuses tasks outside the stated scope.\n- Given the canonical problem (\"I want build a code planner agent ,(basically a planner service, which does the \"), the agent produces a plan in ≤ 200 tokens.\n- When asked \"what's different from Devin (Cognition AI)?\", the agent gives a concrete differentiator, not a marketing line.\n- When asked about GitHub (Microsoft)'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: `LangGraph`, `Claude API (Opus for Phase 2, Haiku for Phase 3)`, `pgvector on Supabase`, `GitHub/GitLab webhooks`, `Next.js`\n- Solo build estimate: 3-4 months to MVP that doesn't embarrass you; 8 months to something you'd show a Series A investor\n\n## Kill prediction\n\nGitHub (Microsoft) could obsolete this in 12-18 months. Copilot Workspace adds RFC ingestion, ADR retrieval, and a versioned plan artifact to its existing issue→plan→code pipeline. It ships as a free add-on for GitHub Enterprise at $21/seat/month. Your standalone product has no answer.\n\n**Survival strategy:** Own the cross-org, multi-VCS (GitHub + GitLab + Bitbucket simultaneously) enterprise segment and the postmortem/ADR organizational memory angle — GitHub will never index your Confluence and your 3-year-old postmortem Notion docs.\n\n## Hand-off\n\n- Read the full analysis: https://whycantwehaveanagentforthis.com/result/planmaster-9000-aka-rfc-to-planmd-whispe-build-code-planner\n- Open in Anthropic Managed Agents: see the deeplink on the result page\n- Claim this idea: https://whycantwehaveanagentforthis.com/result/planmaster-9000-aka-rfc-to-planmd-whispe-build-code-planner#claim\n\n## Build it with a human\n\nBook 20 min and we scope the fastest V0 you can ship — free, no signup: https://cal.com/sattyamjjain\n","scaffold_sh":"#!/usr/bin/env bash\n# Generated by whycantwehaveanagentforthis.com — F-N1 Build-this-with\n# Source: https://whycantwehaveanagentforthis.com/result/planmaster-9000-aka-rfc-to-planmd-whispe-build-code-planner\n#\n# Bootstraps a starter repo for \"PlanMaster 9000 (aka RFC-to-PLAN.md Whisperer)\" with a CLAUDE.md\n# pulled from this site.
