Plugins

1autonomous-sdlcVerification-driven SDLC with parallel worktrees, async subagents, TDD workflow, and Beads integration0.1.0version

2compostOne software-engineering workflow composted from Matt Pocock's skills, superpowers, pstack, Imbue's blueprint, and autonomous-sdlc: specs with BDD acceptance criteria, tracer-bullet issues in your tracker, builds that fit tests into the existing suite, automatic subagent review, browser diff review, semantic lint for Python, a prune skill that keeps docs to what the code can't say, and a turn skill that works in upstream changes.0.32.4version

3compound-knowledgeCapture solved problems, retrieve past solutions, and graduate accumulated knowledge into living context. Skills: compound-capture, compound-retrieve, compound-graduate.0.10.2version

4hexagonal-agentsBuild web apps where an AI agent dynamically generates HTML UI using hexagonal architecture with HTMX1.6.2version

5learn-harnessTurn a Claude project or a folder into a learning harness for one subject. Lesson sessions probe your edge, plan a minimal dependency tree, and teach one checked reasoning step at a time; Practice sessions train retrieval with a hint ladder; Field sessions grade an artifact you produce against a pre-committed rubric. A knowledge graph, an append-only ledger and a frontier record carry it across sessions. Adapted from learnharness.0.1.0version

6mochi-creatorCreate evidence-based spaced repetition flashcards using cognitive science principles. Applies the 5 properties of effective prompts for long-term retention.1.5.0version

7observability-harnessInstall a local, Docker-free OTLP observability stack (OpenTelemetry → Vector → JSONL, optionally VictoriaLogs + VictoriaMetrics) into a project and instrument the code, with a scan-and-propose step for domain-appropriate spans and metrics — then query that telemetry as a development feedback signal (observability-query skill, status --json contract, scripted end-to-end verify).0.3.1version

8superfanSuperfans: one headless Claude per component, obsessively watching its telemetry through your read-only MCP servers (Splunk, Prometheus, Kubernetes, ...) on a local schedule. Findings land in a local inbox, page-worthy ones raise a clickable desktop notification that opens a triage session, and every verdict feeds a ledger that teaches the superfan what normal looks like.0.1.0version

9understandProcess information for real understanding with the explain-back skill: explain from memory, grade against the real source, struggle-then-teach per gap, output Mochi cards and a resumable session record. An antidote to the illusion of clarity.0.2.3version
