EXTENSIONS

Dispatch agent-browser commands as a single subprocess via `agent-browser batch --json` so cookies and Chromium state persist across every step. Supports {{secret:NAME}} placeholders for credentials.

Post Block Kit messages to Slack from swamp models and workflows, with optional file attachments uploaded via the modern external-upload flow. Three methods: send (text + blocks + optional thread reply), sendWithFiles (uploads local files first, then posts a message referencing them), and verifyAuth (auth.test smoke check after token setup).

Gather a Linear user's daily activity — issues completed, moved to review, created, comments authored, and in-flight assignments. Read-only, scoped to configurable team keys. Designed as a data source for EOD reports and standup summaries.

Send push notifications via ntfy.sh (self-hosted or public). A single focused model with one method: send a notification with title, message, priority, and optional emoji tags. Works with the free ntfy.sh service or any self-hosted ntfy instance.

Poll open GitHub PRs for new reviews, comments, and check failures with per-PR watermark deduplication and GitHub API rate-limit backoff. One refresh call fetches all activity; downstream models consume the cached feedbackEvent artifacts without making additional API calls.

Reconcile GitHub/Graphite PR stacks with Linear issue states — scan PRs for ticket references, compare states, and transition Linear issues to match.

Invoke CLI coding agents (claude, opencode, amp, gemini) with typed inputs and capture structured outputs — tokens, cost, duration, retries, and exit code. Supports slash command resolution and JSON response parsing.

Find and remove orphaned Docker Compose containers whose git worktree directory no longer exists. Cross-references live compose projects against git worktree paths. Works with any repo that uses worktrees + compose.

Diagnose and prune git worktrees. Parses `git worktree list --porcelain`, validates paths exist on disk, detects stale/locked/prunable entries, and optionally prunes them. Works with any git repository — no project-specific assumptions.

Manage a Ubiquiti UniFi Dream Machine (UDM / UDM Pro / UDM SE) via the legacy Network firewall API: firewall groups, firewall rules, clients, and networks. Complements @stack72/ubiquity (which focuses on traffic collection) by enabling configuration-as-data workflows: sync existing groups/rules into the swamp data model, reconcile group membership, create or delete firewall rules, and toggle rule state.
