Use when the user asks to add support for a new deployment target or platform (e.g., Cloudflare Workers, Deno, Node.js, AWS Lambda), create a new entrypoint, or make the app deployable to a specific environment.
Use when the user asks to add a new MCP tool, create a tool with UI, scaffold a tool, or add functionality to the MCP App server. Also use when adding API-only tools without a UI component.
Use when the user asks to publish to the store, publish to the registry, publish to studio, set up publishing, configure deco.json/app.json for publishing, troubleshoot publish errors, or understand how the deco store publish flow works.

Template remote: git@github.com:decocms/mcp-app.git. Fetch latest, analyze changes with parallel subagents, present migration plan, apply after user approval.

git fetch template main
# Find base commit (try in order):
git merge-base HEAD template/main # A: shared history
git log --oneline --reverse | head -5 # B: check initial commit
# C: ask user which version they started from
# Changelog:
git log --oneline <base>..template/main
git diff <base>..template/main --stat
If no common ancestor (GitHub "Use this template"), diff full template against user's code file-by-file.
Each subagent compares <base>..template/main for its file category, checks if user also modified those files, and recommends APPLY (no conflict), MERGE (both sides changed), or SKIP (user deleted/replaced). Output as markdown table.
| # | Category | Files to Analyze |
|---|---|---|
| 1 | Infrastructure | vite.config.ts, tsconfig.json, biome.json, package.json scripts, .github/workflows/*, scripts/*, index.html |
| 2 | Dependencies | package.json deps/devDeps — new, removed, version bumps (flag breaking major bumps) |
| 3 | Framework Core | web/context.tsx, web/router.tsx, web/types.ts, web/app.tsx, api/app.ts, api/types/env.ts |
| 4 | UI Components | web/components/ui/*, web/lib/*, web/hooks/*, CSS files (shadcn = usually safe to replace) |
| 5 | Docs & Skills | CLAUDE.md, AGENTS.md, README.md, .claude/skills/**/* |
Compile subagent results into:
## Migration Plan: <base_short> → <latest_short>
- X commits, Y files changed
1. **Auto-apply** (no conflicts): [files]
2. **Merge required** (user also modified): [files]
3. **Skip** (user deleted/replaced): [files]
4. **Manual review** (breaking changes): [files]
### Breaking Changes: [list]
Present to user. Do NOT apply until approved.
git checkout template/main -- <file>bun install.bun install && bun run check && bun run ci:check && bun run build && bun test
If checks fail, dispatch a subagent to diagnose: template incompatibility, bad merge, or missing dep.
| Category | Files | Strategy |
|---|---|---|
| Infrastructure | vite.config.ts, tsconfig.json, biome.json, index.html | Replace |
| Build Scripts | package.json scripts | Merge (user adds TOOL= entries) |
| Dependencies | package.json deps/devDeps | Merge (keep user's, update template's) |
| Framework Core | web/context.tsx, web/router.tsx, web/types.ts, web/app.tsx | Merge carefully |
| Server Core | api/app.ts, api/types/env.ts | Merge carefully |
| UI Components | web/components/ui/*, web/lib/* | Replace (shadcn standard) |
| Example Tool | api/tools/hello.ts, web/tools/hello/ | Skip if user deleted |
| User Tools | api/tools/*, web/tools/* (non-hello) | Never overwrite |
| CI/CD | .github/workflows/* | Replace unless customized |
| Docs | CLAUDE.md, README.md | Merge |
| Skills | .claude/skills/* | Add new, don't overwrite |
| Mistake | Fix |
|---|---|
| Overwriting TOOL_PAGES in router.tsx | Merge: keep user's entries, adopt structural changes |
| Replacing package.json entirely | Merge deps/scripts separately |
| Losing user's resources in api/app.ts | Merge: preserve user's resource registrations |
Not running bun install after dep changes | Always install before type-checking |
| Restoring files user intentionally deleted | Check git log for deletion before restoring |
