Make Plan (Phased Implementation Planner)

What it does

Puts Claude in an orchestrator role that authors a phased implementation plan instead of diving straight into code. Three mechanics matter most:

• Mandatory Phase 0 — Documentation Discovery: subagents read real docs, examples and existing patterns to build an "Allowed APIs" list with cited sources, so the plan never depends on invented methods.
• Every phase carries four parts: what to implement (framed as copy this pattern rather than transform this code), documentation references with file/line pointers, a verification checklist, and anti-pattern guards.
• Subagent reporting contract: sources consulted, concrete findings (exact signatures/paths), copy-ready snippet locations, plus a confidence note and known gaps. Sourceless conclusions get sent back for rework.

Because each phase is self-contained with its own doc references, you can execute phase 2 tomorrow in a brand-new context.

Who it's for

• Anyone whose agent hallucinates APIs or drifts halfway through a large feature
• Developers splitting long work across multiple sessions and wanting a written plan artifact
• Teams doing SDK/library migrations where matching official docs is non-negotiable
• Workflows that separate research (subagents) from synthesis (orchestrator)

Example uses

1. SDK v1 → v2 migration: Phase 0 extracts the real v2 session API from docs; later phases say "copy the pattern at docs/examples.ts:45-60" and include grep checks for deprecated calls.
2. New feature design: ask for a plan for a notification center — you get separate UI, API, migration and test phases, each with a concrete proof-of-done step.
3. Multi-session refactor: run Phase 1 today, open a fresh chat tomorrow and run Phase 2 with no re-explaining, since the phase embeds its own references.
