Plugins

Agents

Plugin	Description
task-orchestrator	Project analysis and planning — decomposes complex tasks, creates implementation plans, identifies risks

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

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)

doc-curator	AI artifact cleanup agent — detects and removes AI-generated comments, excessive documentation, and non-professional code patterns	quality	./agents/doc-curator
review-toolkit	Comprehensive PR review pipeline: a pre-review readiness gate (stops on merge conflicts or red code-related CI with a fix-it note, no verdict), branch-level analysis with merge-base attribution (the verdict is decided only by defects the diff introduced, worsened, or interacts with — purely pre-existing defects are reported in full in a separate outside-findings section and routed to a filed issue, parked branch, or memory entry instead of blocking), sequential Claude+Codex dual-model review with evidence-based verification, and opt-in GitHub PR review publishing under a five-frame substance framework. A value/design gate weighs whether the change should exist at all — value versus permanent maintenance cost, right layer, root cause in-repo versus upstream — and can block a PR even when the code is flawless. Remedies stay proportional: changed logic needs tests in the existing test surface, fixed prose is its own deliverable, and a new checker or guard script is never a required remedy. Findings carry git-computed origin labels (feature vs churn) that diagnose diverging review loops without ever touching the verdict. Reviews land on an LGTM or NOT LGTM verdict, compatible with non-blocking recommendations; the only no-verdict path is the readiness gate's fix-CI / fix-conflicts note.	productivity	./skills/review-toolkit
