All Skills

DaisyUI + Tailwind CDN design system spec. Preloaded into design-related agents and referenced by design skills.

Checklist and automation guide for adding a new skill to the OPC Skills project. Ensures all required files, metadata, logos, and listings are created before release. Use when adding a new skill, publishing a skill, or preparing a skill for release.

Create or update AgentSkills. Use when designing, structuring, or packaging skills with scripts, references, and assets.

Use when reviewing code for security vulnerabilities, implementing authentication/authorization, handling user input, or discussing web application security. Covers OWASP Top 10:2025, ASVS 5.0, and Agentic AI security (2026).

Clear description of what this skill does and when to use it. Include trigger keywords and contexts inline, e.g. "Use when user wants to X, Y, or Z."

GitLab container registry operations via API. ALWAYS use this skill when user wants to: (1) list container repositories, (2) view/delete image tags, (3) clean up old images, (4) manage Docker registry.

Extract tribal knowledge from code, documentation, and commit history to preserve institutional memory

Generate and edit images using Google Gemini 3 Pro Image (Nano Banana Pro). Supports text-to-image, image editing, various aspect ratios, and high-resolution output (2K/4K). Use when user wants to generate images, create images, use Gemini image generation, or do AI image generation.

Generate shell completion scripts for bash, zsh, and fish from CLI command definitions. Creates intelligent completions with argument suggestions, file completions, and dynamic values.

Template loading, variable filling, and scaffolding for all GSD artifacts. Manages 22+ templates covering every document type in the GSD system, from PROJECT.md to milestone archives.

This skill provides a curated set of cross-platform design guideline prompts for building consistent, high-quality UIs. Each guideline defines common rules, component-specific guides, and an auto-derived token system — all driven by minimal user inputs.

--- name: ad-frequency-capper description: "Ad fatigue kills ROI. This agent tracks the relationship between 'Frequency' (Avg times seen) and 'CTR' or 'CPA' in your campaign data, identifying the exact tipping point where performance degrades so you can set a cap." version: 1.0.0 category: Paid Med

Generate ASCII art from images or text using shape vector rendering. Creates sharp-edged ASCII art banners, converts photos to terminal art, and renders text with customizable fonts.

Continuous learning — hooks observe failures and prompt reflection, sibling synergy deepens analysis with history and tool discovery

Guide users through a structured workflow for co-authoring pristine, standardized documentation (READMEs, proposals, specs). Focuses on clarity, formatting, and reader comprehension. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.

Use when writing large files (>1000 lines), editing after many operations, or configuring hooks in Claude Code.

Automatic history search — checks past sessions before web research, planning, and debugging, siblings deepen coverage

Prompt rhetoric coach — deterministic scoring and restructuring using Anthropic best practices

Provides KISS, YAGNI, and SOLID code quality principles for clean code,

Automated detection of code smells and anti-patterns to identify refactoring opportunities

Execute automated AST-based code transformations for large-scale refactoring and migration

Add Agent Swarm (Teams) support to Telegram. Each subagent gets its own bot identity in the group. Requires Telegram channel to be set up first (use /add-telegram). Triggers on "agent swarm", "agent teams telegram", "telegram swarm", "bot pool".

Implement OpenAI Harness Engineering practices in any repository. Use when setting up or refactoring agent-first workflows, writing or upgrading AGENTS.md and PLANS.md, creating deterministic smoke/test/lint/typecheck harness commands, defining strict architecture boundaries and data-shape contracts, wiring observability from day 1, and adding entropy-control checks plus CI automation for reliable autonomous runs.

Execute Apple and Swift tasks through Xcode MCP tools first, with strict workspacePath-based tab resolution and structured fallback handoff when MCP tools are unavailable, time out, or cannot satisfy the operation. Use for MCP-first execution routing or when the user asks to customize this skills MCP retry/handoff policy.
