build-vs-buy-decision

Helps a solo founder or small team decide whether to build a feature in-house, buy/integrate a SaaS, or defer it. Considers MRR stage, team capacity, vendor lock-in risk, ongoing maintenance cost, and the "default to building" indie bias. Invoked when the user asks "should we build or buy [feature]", "is it worth integrating [tool]", "should we replace [vendor] with our own implementation", or "what's the cheapest way to ship [capability]".

Code & Development Listed

content-calendar-planner

Builds a 30/60/90-day cross-platform content calendar for a vendor across Instagram, TikTok, LinkedIn, X, YouTube Shorts, and newsletter. Takes a theme and cadence as input, produces a dated calendar with hooks, hashtags, CTAs, and a repurposing graph showing which posts feed which platforms. Use when the user says "plan content for next month/quarter", "build a content calendar", or "I need 30 days of posts".

explore-codebase

Systematic codebase onboarding. Builds a mental model of a new or unfamiliar project by exploring structure, architecture, key data models, entry points, and auth patterns.

extract-docs

Systematically extract knowledge from scattered documentation to prevent catastrophic forgetting. Creates structured extraction reports with status tags.

fix-issue

Investigate and fix a GitHub issue or bug report. Reads the issue, reproduces it, identifies root cause, implements fix, adds regression test.

Testing & QA Listed

Web & Frontend Listed

gui-ux-expert

Quick GUI/UX/UI design consultations and recommendations

hardware-calculator

Quick VRAM/RAM calculations, hardware recommendations, feasibility checks for AI models

idempotency-keys

Designs the idempotency strategy for a state-changing operation - key derivation, storage choice, TTL, collision handling, and threading through downstream side effects. Use when adding a new endpoint with side effects, hardening an existing one, or designing a workflow that survives retries

interview

Interview the user using AskUserQuestion to discover requirements for a feature or task. Probe technical implementation, UX, edge cases, and constraints. Writes final spec to SPEC.md.

kg-research

Research using ONLY knowledge graph semantic search (no file tools, forces KG-first approach)

photoshop-scripting

Writes Adobe Photoshop automation scripts in UXP (JavaScript) or legacy ExtendScript (JSX), and GIMP scripts in Python (Script-Fu fallback). Use when a repetitive Photoshop task needs to run on dozens of files, when a custom panel/plugin is wanted, or when an Action recorder won't capture the logic needed.

react-patterns

React best practices - component patterns, state management selection, performance optimization, testing strategies

repro-audit

Audits a scientific project for reproducibility — environment pinning, seed setting, data hashing, notebook discipline, workflow orchestration, and provenance capture. Use when the user asks "is this project reproducible", "what's missing for a reviewer to rerun this", "audit my repo before submission", "why do I get different results each run", or before submitting code with a manuscript.

saas-metrics-health-check

Performs a diagnostic on a SaaS product's revenue and retention metrics from a CSV or spreadsheet of customers/subscriptions/events. Computes MRR, ARR, churn (gross/net), LTV, CAC, payback period, quick ratio, and cohort retention; flags anomalies; identifies the single highest-leverage fix.
