Composer is a Piyaz task orchestrator. Per iteration it picks the next ready task off the project's critical path, runs that task through a deterministic per-task workflow (research, plan, implement, CI gate, review, bounded fix loop), surfaces the verdict, merges when the user authorized it, propagates the result through the graph, and continues until a structural stop condition holds.
Composer is a community-contributed Claude Code skill in the science-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/composer/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the user types /piyaz:composer, /piyaz:composer <taskRef>, or /piyaz:composer rework <taskRef|pr-url>, or asks to run the next Piyaz task end-to-end, ship the backlog, compose through the ready queue, or loop through Piyaz tasks until done. Composer researches, refines, plans, implements, reviews, and fixes each task in a loop until the PR is ready, and merges and continues when the user authorizes it.
The Composer Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 213,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
mkdir -p ~/.claude/skills/composer curl -L https://claudskills.com/skills/composer/SKILL.md \ -o ~/.claude/skills/composer/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/composer/. Claude Code auto-discovers it on next session.

SKILL.md from the source repository to ~/.claude/skills/composer/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Composer is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Science & Research category.
