ai-engineering-plugin
Claude Code plugin for prompt engineering — drafting, evaluating, cataloguing, and versioning prompts. Ships craft / eval / catalog / version primitives plus a provisioning skill for two workspace variants: a curated prompt-library and a combinatorial prompt-factory.
Part of the danielrosehill Claude Code marketplace.
What you get
Primitives (always available once the plugin is installed)
Core prompt-engineering commands (/ai-engineering:*):
craft-prompt — draft a new prompt with full metadata.eval-prompt — score a prompt against quality heuristics and record the eval.catalog-prompt — generate or refresh a browsable catalog of all prompts.version-prompt — bump a prompt's version, archive the previous, append a changelog entry.search-prompts — search across the library or factory by keyword, tag, category, or use case.
Factory-specific commands:
configure-variables — define or edit the variable dimensions used by a prompt-factory workspace.generate-prompts — assemble prompts from variables and templates (single, batch, or full matrix).
Agent:
prompt-engineer — autonomous prompt-engineering subagent for multi-step crafting, evaluation, and library maintenance tasks.
Provisioning skill
/ai-engineering:new-workspace <name> [--variant=prompt-library|prompt-factory] [--local-only] [--private]
Scaffolds a new workspace (CLAUDE.md + variant-appropriate folders), personalises it from ~/.claude/CLAUDE.md, and (by default) creates a public GitHub repo for it.
Pattern
Primitives live in the plugin → globally available from any cwd.
Workspace scaffolds are provisioned as data → no .claude/ tree inside provisioned workspaces.
Plugin updates never touch your workspace data.
See PLAN.md in Claude-Workspace-Reshaping-190426 for the full pattern spec this plugin follows.
Variants
prompt-library (default) — curated, category-organised collection of individual prompts with rich frontmatter for search and reuse.prompt-factory — combinatorial prompt generation. Variable dimensions, assembly templates, generated outputs, and evaluations.
