Skills for agents.

Downloadable skills that teach Claude Code (or any coding agent that reads URLs) how to design Match Day stages from scratch — interview-driven, USPSA-safe, master-shooter informed.

Skill · v1 · single stage authoring

stage‑builder

End-to-end skill that interviews you (difficulty, round count, movement, symmetry, design philosophy), plans an original USPSA-style stage against master-shooter principles + safety rules, then builds it incrementally in the Stage Setter editor with screenshots between chunks. Iterates from your critique until you accept the layout, then saves a valid Match Day stage JSON. It won’t always be perfect, but it produces a solid jumping-off point you can refine in the editor.

Install (Claude Code)

curl -sSL https://itsmatchday.app/skills/stage-builder.zip -o /tmp/stage-builder.zip \
  && unzip -o /tmp/stage-builder.zip -d ~/.claude/skills/ \
  && rm /tmp/stage-builder.zip

Restart Claude Code (or start a new session) and trigger the skill by saying "build me a stage", "design a field course", or similar.

Not using Claude Code?

The skill is plain markdown — point any agent that reads URLs at SKILL.md as a prompt, and have it fetch the referenced files on demand. For just the stage JSON format (no skill, no interview), see AGENTS.md instead.

Skill · v1 · whole-match composition

match‑builder

For match directors: compose a complete USPSA match the way you'd brief a smart helper — "5 stages, balanced character, ~120 rounds, 1 classifier, our usual venue." The skill interviews you, picks a balanced selection from the bundled classifier set (plus any custom stages you name), drives the Stage Setter editor's Match Builder dialog, and produces a .usmatch file ready to share with your club. Saves your venue + MD profiles to ~/Documents/Match Day/profiles/ so you don't re-type them every month.

Deep-link to the editor

The skill writes the final .usmatch file to disk and can also hand you a one-click link that opens the match pre-loaded in the Stage Setter editor's Match Builder: https://itsmatchday.app/build/?match=<url-or-base64>. Same shape as ?stage=, but for matches.
