Yesterday-AI

Create Excalidraw diagram JSON files that make visual arguments -- workflows, architectures, concepts. Use when the user wants to visualize systems, processes, or ideas as .excalidraw files. Covers design methodology, section-by-section building, render-validate loop, and quality checklist.

Manage Webflow sites via the official Webflow MCP server -- pages, CMS, assets, components, styles, variables, custom code, comments, localization, and publishing. Covers the headless Data API tools and the Designer API tools (which need the Webflow Designer open in the foreground). Use when: reading, auditing, or editing a Webflow site; building or duplicating pages; managing CMS collections or assets; or adding legal/marketing pages. This plugin ships the Webflow MCP server; just authenticate (OAuth).

Turn an existing skill or a fresh idea into a catalog-ready shareable skill -- run the quality gate, decide public-vs-private catalog and standalone-vs-bundle placement, pick the category, scaffold SKILL.md (+ optional .plugin.json), update the catalog docs, and open a PR to main. Use when adding a new skill to this repo, promoting a personal or ad-hoc skill into a shareable one, or routing a skill into the right catalog.

Manage Paperclip AI companies, agents, issues, projects, goals, routines, costs, and secrets via REST API. Use when creating companies, hiring agents, assigning tasks, managing budgets, approving hires, or checking dashboards on a Paperclip instance.

Generate professional consulting deliverables: Excalidraw diagrams, Mermaid visualizations, Reveal.js/Marp presentations, draw.io architecture diagrams, one-pagers, and proposal documents. Use when a user asks for visual artifacts, slides, diagrams, architecture visuals, consulting documents, pitch decks, workshop materials, or any creative deliverable for client-facing or internal use. Covers the full "Consulting as Code" creative pipeline.

Build distinctive, production-grade frontend interfaces with high design quality. Use when asked to build websites, landing pages, dashboards, web apps, or any web UI that should look polished and modern. Generates creative, polished code that avoids generic AI aesthetics. Includes Yesterday corporate identity briefing for branded reports and deliverables.

Audit this repo's skills + plugins on three axes -- (1) leaks of personal info or Yesterday-internal references in user-facing artifacts, (2) catalog consistency (folder/name/dep/install-target alignment), (3) plugin-spec compliance (Claude Code + Cursor manifest schemas, layout rules). Reports findings as a triage list; does not auto-fix. Use before publishing, before merging skill PRs, or as a periodic hygiene pass.

Semantic web search via Exa AI API. Returns full-text content, not just snippets. Use for deep research, competitor analysis, or finding specific technical content.

Orchestrate specialized coding agents in isolated worktrees for parallel development tasks.

End-to-end skill for curated team news digests. Covers the full pipeline: team inbox (manual submissions & co-authored drafts), source aggregation (RSS, Twitter, GitHub, web search), research & fact-checking, relevance scoring, article formatting (5 templates), and scheduled delivery to Slack/Discord/WhatsApp. Handles the critical handoff between conversational sessions (where links are received) and isolated cron sessions (where digests are built).

Discover available tools, sub-agents, and skills at session start or when unsure about capabilities.

Foundational philosophy for autonomous agent work. Breaks analysis paralysis and enforces tangible output per interaction. Use when: a conversation feels circular, a session risks ending without an artifact, or an agent needs a reminder to act instead of plan. Generic -- applies to any domain or toolchain.

Qualified, critical code reviews using GitHub's pending review API. Inline comments, verification, and validation.

Standardized Git + GitHub workflows for AI agents. Branching, committing, PRs, reviews, CI checks.

Periodic scan of GitHub repos for open issues. Classifies issues into actionable queues (new, needs-clarification, ready-to-implement, in-progress, blocked) and persists state across heartbeat cycles. Use when an engineering agent needs to autonomously discover and triage work.

End-to-end workflow for turning a GitHub issue into a merged PR. Covers issue analysis, branch creation, implementation, PR with reviewer assignment, and handling review feedback loops. Use when an engineering agent picks up an issue from a patrol queue and needs to implement it.

Manage Paperclip AI companies, agents, issues, projects, goals, routines, costs, and secrets via REST API. Use when creating companies, hiring agents, assigning tasks, managing budgets, approving hires, or checking dashboards on a Paperclip instance.

Set up and manage Paperclip Routines — recurring scheduled tasks that replace expensive always-on heartbeats. Use to create cron-based, webhook-triggered, or API-triggered routines for agents, reducing token spend while keeping agents responsive. Covers routine CRUD, triggers, concurrency policies, and suggested routine patterns for common agent roles.

Analyze a Paperclip company's issue history, agent health, recurring failure patterns, and project architecture to design and provision tailored routines with cron/webhook triggers. Replaces expensive always-on heartbeats with targeted, data-driven scheduled runs. Use when setting up routines for a new or existing company, or when optimizing token spend on agent heartbeats.

Prepare a new release by updating CHANGELOG.md, verifying documentation (README.md, CLAUDE.md, AGENTS.md, ROADMAP.md, docs/), bumping patch version in package.json, building, and suggesting publish commands. Use when asked to release, bump version, prepare release, or publish.

Publish or update an HTML5 game on itch.io via the butler CLI. Covers install, login, channel push with versioning, and first-time page setup. Use when deploying a web game build (e.g. dist/) to an itch.io channel.

Deploy, manage, and debug services on Railway via the Railway CLI. Covers authentication, project + service creation, env variables, private networking, logs, and config-as-code. Use whenever creating, deploying, or troubleshooting Railway services. See references/ for the full CLI command reference and a Next.js+Prisma deploy recipe.

Manage infrastructure via OpenTofu (Terraform fork). Use when: provisioning servers, DNS, or cloud resources. Covers: init, plan, apply, destroy, import.
