Run two heterogeneous fresh-context Herdr reviewers against both code quality and a governing plan, then synthesize evidence-backed feedback. Use when the user asks for a dual or adversarial review, code-versus-plan verification, or independent Claude and Pi reviewers before deciding whether a PR needs changes.

Control herdr from Codex. Use when the user says "use Herder" or asks to inspect, focus, prompt, spawn, or manage herdr workspaces, tabs, panes, or agents from a Codex session, without deciding whether they are inside or outside herdr.

Use when the user explicitly asks Codex Desktop or another shell outside Herdr to create, inspect, prompt, follow up with, or monitor Herdr agent tabs, or when the `codex-herdr` router skill hands off external control.

Fan out a user-provided task list into one reviewed PR per task through Herdr, then shepherd the PR fleet through CI and review without merging. Use when the user asks to fan out PRs, parallelize backlog items into separate PRs, or autonomously drive multiple agent-owned PRs to green.

Inspect and import content into my self-hosted AutoCaliWeb library. Use for catalog status, search, recent imports, shelves, metadata, or importing an ebook, comic, PDF, or audiobook.

Access and manage my FreshRSS instance. Use for RSS reading, search, recommendations, subscriptions, auto-categorization, uncategorized-feed cleanup, or subscribing to an email newsletter through Kill the Newsletter.

Browse and manage my TubeArchivist archive. Use for channels, videos, downloads, tasks, search, ordinary subscriptions, or a curated creator import that queues popular videos and exposes the channel in Jellyfin.

Create thorough PRDs through repo analysis and deep user interviews. Use for "create a PRD", "write requirements", "product spec", or "implementation plan". Writes PRDs to docs/prds and can optionally decompose them into local issue markdown files.

Open Plannotator's annotation UI for a markdown file, converted HTML file, URL, or folder and then respond to the returned annotations.

Turn an idea or objective into a goal package for /goal. Interviews the user, builds a reviewed fact sheet via Plannotator, then explores the codebase to produce an execution plan.

Add a new service to the Homepage dashboard. Use when a new container or VM has been set up on Proxmox and needs to be added to Homepage. Discovers IP and port automatically from the container.

Inspect and manage my self-hosted Caddy reverse proxy via its admin API. Use when the user asks about Caddy, mentions reverse proxy routes, virtual hosts, TLS/cert issues for internal `.lan` domains, upstream health, or wants to view/reload the active Caddy configuration.

Inspect and search my self-hosted Immich photo/video library. Use when the user asks about Immich, photos, videos, albums, people/faces, recent uploads, library stats, server storage, or background jobs.

Inspect my self-hosted Jellyfin media server: server status, users, libraries, sessions, now-playing, recently-added, item search, library counts, and scheduled tasks. Use when the user asks about Jellyfin, what's playing, who's watching, what was just added, library size, or asks to run a Jellyfin task.

Browse, search, approve, decline, and inspect media requests in my self-hosted Jellyseerr. Use when the user asks about Jellyseerr, mentions media requests, asks to approve/decline a request, search for a movie or show to request, check what was recently added, list users, or view open issues.

Search across indexers and manage my self-hosted Prowlarr. Use when the user asks about indexer search, finding a release, indexer health/stats, listing or testing indexers, syncing indexers to Sonarr/Radarr, or mentions Prowlarr.

Search, add, inspect, and manage movies in my self-hosted Radarr library. Use when the user asks about movies, mentions Radarr, asks to add/remove a film, check what's downloading, what's upcoming, what's missing, view queue/history, manage collections, or trigger searches.

Inspect and control my self-hosted SABnzbd Usenet downloader. Use when the user asks about SABnzbd, NZB downloads, the Usenet queue, download history, server stats, or asks to pause/resume/delete a download.

Inspect the local tailnet via the Tailscale CLI. Use when the user asks about tailscale, tailnet peers, exit nodes, MagicDNS, who's online over Tailscale, or wants to ping/whois a Tailscale host. Read-only — no mutations to tailnet state.

Search, add, inspect, and manage TV shows in my self-hosted Sonarr library. Use when the user asks about TV shows, mentions Sonarr, asks to add/remove a series, check what's downloading, what's upcoming, what's missing, view queue/history, or trigger searches.
