Plugins

Agents

| Plugin | Description | | --- | --- | | task-orchestrator | Project analysis and planning — decomposes complex tasks, creates implementation plans, identifies risks | | tech-oracle | Technical architect — manages .architecture.yaml, creates ADRs, evaluates technology choices | | gopher-builder | Go developer — TDD specialist for cloud-native apps with Echo, slog, cockroachdb/errors | | snake-charmer | Python developer — TDD specialist treating code as art, with FastAPI, Pydantic, structlog | | templ-weaver | Frontend specialist — Go Templ + HTMX with server-first rendering and WCAG 2.1 AA accessibility | | kube-pilot | Kubernetes specialist — secure, production-ready K8s manifests and ArgoCD with zero-trust networking | | chart-builder | Helm chart TDD specialist — production-ready charts with helm-unittest | | docker-smith | Containerization specialist — optimized, secure Containerfiles with multi-stage builds | | code-guardian | Code quality validation — linters, tests, security checks, .architecture.yaml compliance | | doc-curator | AI artifact cleanup — removes AI-generated comments, excessive docs, non-professional patterns |

Skills

| Plugin | Description | | --- | --- | | review-toolkit | Code review pipeline: branch review with merge-base attribution (only defects the diff introduced, worsened, or interacts with block; pre-existing ones are reported separately and never dropped), churn diagnostics for review loops, PR review with a readiness gate (fix-CI / fix-conflicts, no verdict), a value/design gate (should this change exist at all — value vs maintenance cost), dual-model analysis (Claude + Codex), and GitHub PR review publishing with evidence-based verification | | address-pr-comments | Close out unresolved review comments across one or more PRs — verify, fix with auto-pushed signed commits (one per thread), post user-approved replies, restore original branch | | git-tools | Git workflow utilities: fork refresh and repo setup with branch protection | | genname | Generate a /rename command from type, title, and optional PR number | | tldrpr | Generate plain-text TLDR summaries for PRs, ready for Slack | | learn | Analyze the current session and extract key learnings into CLAUDE.md and memory | | renovate-check | Run Renovate locally in dry-run mode, research migration guides, apply selected updates | | agent-father | Interactive guide for creating Claude Code subagents following official documentation standards | | billy | "Where's the proof, Billy?" — stop and prove a claim with deep investigation | | m4b-audiobook | Assemble m4b audiobook from audio files with chapters, metadata, and cover art | | say | Speak text aloud using macOS TTS with automatic voice selection | | slack-formatter | Copy markdown to macOS clipboard as rich HTML + plain-text fallback, ready for Cmd+V into Slack with formatting preserved | | helm-add-gwapi-route | Add or modernize Gateway API *Route templates (HTTPRoute/GRPCRoute/TLSRoute/TCPRoute/UDPRoute) in a Helm chart. Auto-detects add vs update mode per route kind; applies current best practices (named rules, typed filters, optional BackendTLSPolicy). File edits only — no git operations | | pore-analysis | Measure porosity, pore size/shape, lattice period and ordering (psi6, Voronoi, radial g(r) + orientational correlation length) from top-view SEM images of porous films such as anodic aluminium oxide. The agent reads the image to calibrate and crop; a Python core does the morphometry and flags results that contradict physics. Vision decides, Python computes — no hardcoded autodetect | | cleanup | Local disk cleanup: stale git worktrees, dead personal forks, Docker prune (incl. non-default buildx builders and VM disk trim), Go caches, and Homebrew — each report → confirm → execute with interactive prompts, plus a cleanup-all pipeline. Paths are asked, never hardcoded | | become | Session role switches (become:manager, more roles to come). Manager: lead of a subagent fleet — brief teammates, delegate whole loops, approve their output inside the delegated scope, integrate by ground truth, report upward in short digests. Strongest model in the manager seat, explicit opus/sonnet per teammate |

MCP Servers

| Plugin | Description | | --- | --- | | mcp-loki | Grafana Loki — LogQL queries, label discovery, series exploration, index statistics | | mcp-transmission | Transmission — torrent management, session stats, queue and bandwidth control | | mcp-tg | Telegram — MTProto client API, messaging, contacts, groups, channels, media handling |

Hooks

| Plugin | Description | | --- | --- | | golangci-lint | Auto-run golangci-lint on package when Go files are edited | | md-no-hardwrap | PreToolUse hook: reject Write/Edit on markdown files when a paragraph spans more than one line — enforces "one continuous line per paragraph" so renderers wrap to viewer width instead of fighting hardwraps in the source | | worksync | Daily work-sync markdown log — PostToolUse hook captures gh pr/issue create/merge/close automatically, companion skill logs research/ops/checkpoint events (prompts for vault path on install, works with Obsidian, Logseq, or plain markdown) |
