Build, audit, and improve harnesses that make AI coding agents reliable: AGENTS.md/CLAUDE.md instruction files, feature/state tracking, verification gates, scope boundaries, session handoff, memory persistence, context budgets, tool-permission safety, and multi-agent coordination. Use this whenever a coding agent is unreliable across sessions — forgets context, drifts out of scope, claims "done" before tests pass, or starts each session inconsistently — or when creating or assessing AGENTS.md, CLAUDE.md, feature_list.json, init.sh, progress.md, or session-handoff files. Reach for it even if the user never says the word "harness."
Bootstraps a new firstsun-dev project end-to-end: installs relevant skills, scaffolds an agent harness via firstsun-harness, creates the GitHub repo with description/topics, and lists it in the org profile README. Use whenever the user wants to init/bootstrap a new firstsun-dev project or repo — even if they only ask for one part of the flow, since the rest is usually wanted too.
Expert project management for the Firstsun-Dev organization. This skill standardizes issue creation across multiple repositories, ensures all tasks are correctly linked to the central Project Board (#6), and enforces naming conventions. Trigger this whenever the user says "add a task", "create a ticket", "new job", "manage projects", or wants to update task estimates/priorities.
Comprehensive coding conventions and guardrails for Firstsun projects (Astro, React, Cloudflare). Integrates backend, styling, i18n, and testing standards.
Unified CI/CD workflow patterns for monorepos, including path-based filtering, semantic release, and Cloudflare deployment. Replaces the legacy React Native focus with modern web standards.

npx skills add <directory>.npx skills add <path> --full-depth to find all skills.SKILLS_LIST.md.To prevent fragmentation (e.g., mixing search/ and fetch/ for similar tools), you MUST map external skills to our existing local domains/categories:
basic/, develop/, obsidian/, video-design/, writing/.research/firecrawl, but we use basic/, move it to external/basic/firecrawl-search/.Leverage these skills to maintain the repository:
/find-skills: Discover existing skills in the ecosystem to avoid duplication./skills-validator: Validate skills in custom/ or external/ against the agentskills.io spec./skills-creator: Follow guided workflows to create new skills with proper structure./reference pattern to keep skills efficient. Read references/REFACTORING.md for the refactoring SOP../setup.sh registers all local skills (defaults to remote mode to preserve skills-lock.json). Use ./setup.sh --local for active development; the script automatically safeguards skills-lock.json from local path changes../export.sh <domain> imports domain skills to a specific project.npx skills add <path_to_directory> -l to list all detectable skills.Use this workflow to consolidate multiple skills into a single "Gem" instruction set for Google Gemini.
