Claude Code plugins by Joshua Oliphant for productivity and learning workflows
npx claudepluginhub joshuaoliphant/claude-pluginsAdaptive autonomous SDLC with agent teams, native worktree isolation, task management, prompt-based hooks, and prompt objects
Build web applications where an AI agent dynamically generates HTML UI using hexagonal/ports-and-adapters architecture with HTMX for interactivity and MCP tools for data operations
Capture solved problems and retrieve past solutions as structured YAML-frontmatter files. Split into compound-capture (post-solve documentation) and compound-retrieve (pre-work knowledge search) for precise triggering.
Generate autonomous experiment loops with immutable runner scripts, tiered quality gates, secondary metrics, and structured METRIC output.

Create evidence-based spaced repetition flashcards using cognitive science principles from Andy Matuschak's research. Applies the 5 properties of effective prompts (focused, precise, consistent, tractable, effortful) to ensure cards actually work for long-term retention.
Features: Quality validation, knowledge-type workflows (factual, conceptual, procedural, salience), anti-pattern detection, template support, deck management, batch operations.
Requirements: Mochi.cards account + MOCHI_API_KEY environment variable.

Capture solved problems and retrieve past solutions as structured YAML-frontmatter files for grep-based retrieval across sessions and projects.
/plugin install compound-knowledge@oliphant-plugins
Generate autonomous experiment loops that iteratively improve code by editing, running, measuring a scalar metric, and keeping improvements via git commit/reset. Based on Karpathy's autoresearch pattern.
Generates: program.md + auto/run.sh with tiered quality gates, ready to run with claude --dangerously-skip-permissions.
/plugin install autoloop@oliphant-plugins
