Summary

  • Adds the full DevPlan methodology as a standalone Claude Code skill/plugin
  • Zero network dependency — no MCP server, no SSE connections, no timeouts
  • Installs at user scope via /plugin marketplace add + /plugin install

What's included

  • SKILL.md (1,142 words) — Core methodology, interview flow, sub-command dispatch
  • references/templates.md — Brief/plan/CLAUDE.md templates for all 4 project types (CLI, web app, API, library)
  • references/validation.md — Structure + Haiku-executability rules + all battle-tested lessons baked in as hard rules
  • references/agents.md — Executor (Haiku) and verifier (Sonnet) agent generation patterns
  • references/workflows.md — Mermaid/ReactFlow export + progress tracking + issue-to-task
  • scripts/validate-plan.sh — Standalone structural validation
  • scripts/check-haiku.sh — Standalone Haiku-executability checker
  • examples/hello-cli-plan.md — Gold standard reference plan
  • .claude-plugin/plugin.json — Plugin metadata for discovery
  • README.md updated with "NEW — Install as a Skill" section at top

Motivation

The MCP SSE server has reliability issues (connection drops every 300-600s, tools fail to register). A local skill eliminates that fragility entirely. The lessons learned system was intentionally omitted — Nellie supersedes it.

Test plan

  • /plugin marketplace add mmorris35/devplan-mcp-server succeeds
  • /plugin install devplan@mmorris35 --scope user succeeds
  • /devplan invokes the skill
  • bash scripts/validate-plan.sh examples/hello-cli-plan.md passes
  • bash scripts/check-haiku.sh examples/hello-cli-plan.md runs cleanly

Registers the devplan plugin (repo root, source '.') under marketplace name
'mmorris35' so '/plugin install devplan@mmorris35' resolves.
