Plugins

Skills

The ten standalone agent plugins are gone. Nine of their agents ship inside become, renamed to their craft; the tenth was dropped. The old-to-new mapping is in its README.

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 plus the specialist agents they run. Manager (`/become: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. Bundled workforce, spawnable as teammates or callable as `@agent-become:<name>`: architecture (technical decisions, `.architecture.yaml`), go, python, templ (Templ + HTMX), kubernetes (manifests, ArgoCD), helm (charts), containers (image builds), quality (lint, tests, security, then commit and push), hygiene (AI-artifact cleanup)

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
comment-hygiene	SessionStart hook that injects code-comment discipline into every session — every comment must earn its place: say what the code cannot, never duplicate it; bans narration, changelog comments, reviewer asides, signature-restating docstrings, and leaky provenance
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)

Name	Description	Category	Source
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
address-pr-comments	End-to-end closeout of unresolved review comments across one or more GitHub PRs — verifies each thread, fixes legitimate findings with one signed commit per thread, posts approved replies, restores original branch	productivity	./skills/address-pr-comments
git-tools	Git workflow utilities: fork refresh and repo setup with branch protection	productivity	./skills/git-tools
genname	Generate a /rename command from type, title, and optional PR number — pure string formatting utility	productivity	./skills/genname

learn	Analyze the current session and extract key learnings into CLAUDE.md files and memory system	productivity	./skills/learn

helm-add-gwapi-route	Add or modernize Gateway API *Route templates (HTTPRoute/GRPCRoute/TLSRoute/TCPRoute/UDPRoute) in a Helm chart, mirroring its ingress conventions. 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, no push, no PR	infrastructure	./skills/helm-add-gwapi-route
pore-analysis	Measure porosity, pore size/shape, lattice period and ordering (psi6, Voronoi coordination, radial g(r) and 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, so it adapts to different instruments and scale-bar formats.	science	./skills/pore-analysis

become	Session role switches plus the specialist agent workforce they run. Roles: manager — turn the session into the lead of a subagent fleet that briefs teammates, delegates whole loops, approves their output inside the delegated scope, integrates by ground truth, and reports upward in short digests instead of executing directly. Bundled agents, spawnable as fleet teammates or callable directly as @agent-become:<name>: architecture (technical decisions and .architecture.yaml), go, python, templ (Templ and HTMX frontend), kubernetes (manifests and ArgoCD), helm (charts), containers (image builds), quality (lint, tests, security, then commit and push), hygiene (AI-artifact cleanup)	productivity	./skills/become
