color-math-accessibility

Calculate, review, and generate web color systems using RGB, HSL, LAB, OKLCH, contrast ratios, luminance, opacity, blend modes, and light/dark mode transformations. Use when auditing accessible colors, converting color models, deriving palettes, checking WCAG contrast, building theme tokens, or debugging opacity and CSS blend math.

amq-cli

Coordinate agents via the AMQ CLI for file-based inter-agent messaging. Use this skill whenever you need to send messages to another agent (codex, claude, or any named handle), check your inbox, drain queued messages, set up co-op mode between agents, join a swarm team, route messages across projects, or diagnose delivery issues. Also use it when you receive a message and need to know how to reply, inspect receipts, or handle priority. Covers any multi-agent coordination task where agents need to talk to each other — review requests, questions, status updates, decision threads, wake notifications, and orchestrator integration (Symphony, Kanban). For collaborative spec/design workflows specifically, prefer the /amq-spec skill which provides structured phase-by-phase guidance. Not intended for distributed systems design (RabbitMQ, Kafka), CI/CD pipelines, or single-agent tasks with no partner.

amq-spec

Parallel-research-then-converge design workflow between two agents. Use this skill when the user wants two agents to independently think through a design problem before aligning on a solution — "spec X with codex", "design X together", "both agents think through X", "brainstorm architecture together", "parallel research then joint proposal", "think through separately then align", "careful thought from both sides before coding", or any variation where the user wants collaborative design rather than just splitting implementation work. Also use this when you receive a message labeled workflow:spec and need to know the correct receiver-side protocol. Not for sending simple messages or reviews (use /amq-cli), implementing completed designs, or creating document templates.

brainstorming

Use when defining new features, product behavior, UI/component design, architecture choices, contract changes, or ambiguous medium/high-complexity work before implementation, or when the user asks to grill or pressure-test a plan or design.

Color Math Accessibility

Use this skill when colors need to be explainable, accessible, and reproducible. It focuses on color math that affects real UI outcomes: contrast, palette relationships, perceptual lightness, opacity, and blending.

Quick Start

Read guidelines.md to select the smallest relevant file set.

Load references/color-systems/rules.md for implementation decisions.

Load references/color-systems/examples.md when editing code.

Use workflows/audit-color-system.md for multi-step derivation or debugging.
