Agentic System Design

Custom plugins and skills for Claude Code.

Available

The four pitch skills form one suite - preparing a whole pitch -> start with pitch-package (it routes to the others); a single artifact -> call it directly (pitch-craft = words against a clock, demo-video = crisp product footage, pitch-deck = the deck + walkthrough). Full decision guide: skills/README.md.

Plugins

Plugin: Deckling

Generate and refine PowerPoint presentations using Anthropic's Platform Skills API.

/deckling "Quarterly Review - 3 slides"
/deckling "Change title to 'Q4 Results'" --refine quarterly.pptx

See plugins/deckling/README.md for full documentation.

Plugin: MVP Launch

Analyze web app codebases against a battle-tested 10-point MVP launch checklist. Based on "Realistic MVP Launch Checklist (from building 30+ apps)".

/launch-check

The 10-Point Checklist:

1. Stripe Setup (webhooks, trials, failed payments)
2. Mobile-First Design (real device testing)
3. Smooth Onboarding (minimal steps, fast first win)
4. AI & Automation Stability (retries, error handling)
5. Critical Emails (welcome, trial-ending, failed payment)
6. Error Logging (catch bugs before users)
7. User Feedback Loop (simple form or tool)
8. Auth & Roles (secure pages, basic roles)
9. Custom Domain with SSL (no dev URLs)
10. Real Database & Backups (automated backups)

Philosophy: "Don't overbuild. Just make it stable, usable, and something people can trust."

See plugins/mvp-launch/README.md for full documentation.

Plugin: Product Management

AI-native product management for startups. Process signals, not features.

After installing, just ask Claude Code:

"Analyze my product"
"Research competitors"
"Find feature gaps we should build"
"What should we build next?"

Key Commands

/pm analyze     # Deep product understanding
/pm landscape   # Market overview + competitors
/pm gaps        # Batch gap analysis with WINNING scores
/pm file        # Create GitHub Issues for top priorities
/pm roadmap     # Organize into Now/Next/Later

WINNING Filter

Prioritize with objective scoring: WINNING = Pain × Timing × Execution

• 40-60: FILE (high conviction)
• 25-39: WAIT (monitor)
• 0-24: SKIP (not worth it)

spec-kit Integration

This skill handles WHAT to build (product discovery). For HOW to build, use spec-kit:

/pm file → GitHub Issue → /speckit.specify → /speckit.plan → /speckit.implement

The GitHub Issue IS the handoff—no extra command needed.

See plugins/product-management/README.md for full documentation.

Plugin: Rethink Surveys

Survey design framework grounded in proven research methods — Caroline Jarrett's Surveys That Work, Dillman's Tailored Design, and Tourangeau's cognitive model. Captures what people are actually trying to do (past behavior, not hypotheticals) without leading questions, satisficing bait, or shallow Likert noise.

/design-survey     # Interactive design session for a new survey
/critique-survey   # Jarrett-style critique of an existing survey
/turn-into-app     # Turn a finalized design into a working app scaffold

Features:

• 4-part hybrid structure: discovery / diagnostic / intent / segmentation
• Question library with behavioral anchors
• Three battle-tested templates: event organizers, startup founders, gig-economy workers
• Text, voice, and AI-interviewer modalities
• Bundles the rethink-survey MCP server for designing, critiquing, scoring, and clustering survey responses

See plugins/rethink-surveys for full documentation.
