Skills

Reusable skills for Codex and Claude Code, covering product planning, design, Web development, go-to-market work, software engineering, and skill authoring. Each skill lives in skills/<name>/; its SKILL.md describes its task, requirements, workflow, and supporting resources.

Codex

The showxu-skills marketplace publishes one showxu-skills plugin containing the repository's skills/ directory. It needs Codex CLI 0.147.0 or later.

codex plugin marketplace add showxu/skills --ref master
codex plugin add showxu-skills@showxu-skills

Restart Codex after installation. To refresh the marketplace:

codex plugin marketplace upgrade showxu-skills

Check the installed version afterward. Marketplace refresh and installed-plugin activation depend on the host version.

For a local manifest check from this checkout:

codex_test_home="$PWD/.build/plugin-check/codex"
mkdir -p "$codex_test_home"
CODEX_HOME="$codex_test_home" codex plugin marketplace add "$PWD"
CODEX_HOME="$codex_test_home" codex plugin list --available --json

The marketplace's Git source installs the published repository root. Working tree installation checks use an isolated local marketplace as described in skill authoring.

Claude Code

The showxu-skills marketplace publishes one showxu-skills plugin containing the repository's skills/ directory.

claude plugin marketplace add showxu/skills
claude plugin install showxu-skills@showxu-skills

Restart Claude Code after installation. To refresh the marketplace and the installed plugin:

claude plugin marketplace update showxu-skills
claude plugin update showxu-skills@showxu-skills

For a local check from this checkout:

claude_test_home="$PWD/.build/plugin-check/claude"
mkdir -p "$claude_test_home"
CLAUDE_CONFIG_DIR="$claude_test_home" claude plugin validate .
CLAUDE_CONFIG_DIR="$claude_test_home" claude plugin marketplace add "$PWD"
CLAUDE_CONFIG_DIR="$claude_test_home" claude plugin install showxu-skills@showxu-skills

Direct skill installation

Use either plugins or direct installation for a skill. Installing the same skill through both routes can load it twice. Direct copies or links suit local authoring; plugins provide versioned distribution.

After cloning this repository, copy the selected skills/<name>/ directory to the host's user skill directory, or link it for local editing. For example, from the checkout root:

mkdir -p "$HOME/.agents/skills"
ln -s "$PWD/skills/skill-distiller" "$HOME/.agents/skills/skill-distiller"

mkdir -p "$HOME/.claude/skills"
ln -s "$PWD/skills/skill-distiller" "$HOME/.claude/skills/skill-distiller"

Choose an unused destination and restart the host afterward. Requirements vary by skill; consult its SKILL.md before using bundled helpers.

Repository index

• Documentation index: architecture, lifecycle, and reference documentation.
• Repository layout: artifact ownership and placement.
• Skill authoring: trigger contracts, maintenance, package validation, and plugin versions.
• Capability routing: capability areas and skill placement.
• Agent guide: editing routes and guardrails.
• upstreams.yaml: upstream sources and review provenance.
• skills/: skill instructions, references, scripts, templates, and assets.
