firebase-cli
Safety-first Firebase CLI (firebase-tools v15) skill for full project control — deploy, Hosting (sites/channels/rollback), Cloud Functions (+secrets), Firestore (databases/indexes/backups/delete), Realtime Database, Auth import/export, Remote Config, App Distribution, App Hosting, Extensions, Data Connect, Emulator Suite & MCP server. Classifies every command by risk tier via a deterministic classifier script and gates destructive/irreversible/cost-incurring ops behind AskUserQuestion confirmation; enforces the --non-interactive/--force contract so nothing hangs and nothing is auto-confirmed. Wrong-project preflight prevents deploying to prod by accident. Ships a 3-level self-test (static classifier battery, live read-only, guarded live-write w/ cleanup). Use when running, planning, or debugging any `firebase` command.

mongodb-atlas-cli
Comprehensive MongoDB Atlas + mongosh skill for performance auditing, all index types (b-tree/text/2dsphere/hashed/TTL/partial/wildcard/Atlas-Search/Vector-Search), Performance Advisor analysis, query explain, schema advice, backup status, alerts, week-over-week diffs, and additive index creation. Read-only by default; create-index ops gated behind explicit `--confirm`. Hard-blocks any destructive op (delete, drop, restore, pause, terminate, kill, dbuser write, network change). Works against Atlas Cloud (full feature set) and self-hosted/local mongo (mongosh-based subset).
multi-agent-patterns
Master orchestrator, peer-to-peer, and hierarchical multi-agent architectures
n8n-cli
Safety-first n8n management skill — list/inspect workflows, executions, credentials, tags, projects, variables, source-control status; trigger runs (CLI/webhook); activate/deactivate; backup/restore; audit; diff. Two backends auto-detect: REST API (cloud + remote self-hosted, urllib stdlib) & `n8n` CLI (self-hosted only, full surface incl. encrypted/decrypted credential export). Read-only by default; mutations require `--confirm` + dry-run preview. Hard-blocks 14 destructive CLI prefixes (delete, reset, encryption-key, executionData, user-management role changes, mfa, ldap, db ops, license) and 22 DELETE/PUT/PATCH/POST API endpoints (workflows/credentials/executions/users/tags/variables/projects/source-control/license). CLI refusal guard uses flag-stripping + chain matching to block bypasses. URL paths validated against `/api/v1/` allowlist + traversal-resistant. Resource IDs regex-validated before URL interpolation. API key redacted from error output; HTTPS warning on http://. Decrypted credential export double-gated (--decrypted + --confirm-secrets). Output paths sanitized. n8n REST API uses `/activate`+`/deactivate` for both 1.x & 2.x — public API has no `run` endpoint, so trigger_workflow is CLI-only w/ webhook URL helper. Faster than n8n MCP for bulk reads, backups, exports, diffs, CI/cron; complements MCP which is better for workflow authoring.
natural-language
Shapes how every reply to the user gets written - plain everyday words instead of corporate or AI-sounding phrasing, real sentences instead of bullet-heavy formatting, no forced dash punctuation, and at most a rare bit of dry humor when it genuinely fits. Use this for every conversational response written to the user in this project, not only on special request - check it before replying, the same way a person reads over their own message before hitting send.
