Answer natural language questions and perform analysis on GKE cluster and workload costs using BigQuery billing exports, cost allocation data, and live cluster monitoring metrics. Use when querying GKE costs across projects, namespaces, or workloads, analyzing billing reports in BigQuery (`bq`), checking cluster cost budgets (`gcloud billing`), or diagnosing cost drivers like pod requests vs. actual utilization (`kubectl top`). Don't use for applying cost optimization changes, creating rightsizing manifests (VPA/MPA), or selecting ComputeClasses (use gke-cost-optimization instead).

Explain the last message, or a supplied file, link, or passage, in plain language a person follows on the first read. Use when the user invokes wtf because they did not follow something. Use ce-explain to investigate how or why code works, and ce-noslop to rewrite prose.

Query and invoke tools on MCP servers using fastmcp list and fastmcp call. Use when you need to discover what tools a server offers, call tools, or integrate MCP servers into workflows.

Refresh installed NanoClaw channel and provider payloads (channels from their registry branch, providers from their skill payload) with fork-safe remote resolution and a blocking structured result. Use after updating NanoClaw or whenever installed channel/provider code may be stale.

Root-cause a reconciliation break to its source transaction or posting — follow the audit trail from the break row back to the originating entry on each side and state what differs and why. Use after gl-recon has classified a break.

Use for the CODE half of a managed Intelligence Channel with Slack or Microsoft Teams: customising the Channel a CLI-scaffolded project already ships, or — for a project the CLI did not generate — writing the Channel declaration, the long-running host, and the awaited activation call. Teams provider setup is in scope, because the CLI or dashboard wizard performs it. Creating a Slack app for the first time is not: if no Slack app exists yet, use setup-slack-channel for the provider half and return here for the code.

Verify a change end to end on the Novu Box, a full Novu Cloud stack in one container on Cloudflare. Use when a change to apps/, libs/, packages/, enterprise/ or playground/ needs proof that it works, or when asked to check, verify, demo or reproduce something on the box.

Git worktree command reference: path naming, create/remove/prune, `.env` copy and cleanup. Use when implementing or debugging worktree setup — not as the primary user-facing workflow (see nv-worktree-create).

Use when asked to find or plan Cherry Studio cleanup, simplification, refactoring, dead-code removal, duplicated state removal, unnecessary APIs, speculative generality, or library replacements, especially when the result should become evidence-backed proposed Agent Notes.

Retrieve the composite country resilience score (0-100) and its domain/pillar breakdown for a single country. Use when the user asks how resilient a country is, or wants its numeric resilience score, trend, or per-domain breakdown.

Retrieve composite country risk intelligence — Country Instability Index (CII), travel advisory level, and active sanctions exposure — for one country by ISO code. Use when the user asks how risky or unstable a country is right now.

Diagnosis loop for hard bugs and perf regressions. Trigger: diagnose, debug this, something broken/failing/slow.

Ingest a source into the wiki — read it in full, compile durable cited pages, and update the index, log, and overview in one commit. Accepts files in raw/, URLs to fetch and archive first, a directory of a code repo read in place, or the answer /kb-ask just gave. Use when the user says ingest, compile this source, add this to the wiki, or pastes a link to read into it.

Monitor Nx Cloud CI pipeline and handle self-healing fixes. USE WHEN user says "monitor ci", "watch ci", "ci monitor", "watch ci for this branch", "track ci", "check ci status", wants to track CI status, or needs help with self-healing CI fixes. Prefer this skill over native CI provider tools (gh, glab, etc.) for CI monitoring — it integrates with Nx Cloud self-healing which those tools cannot access.

Expert guidance on Nix, NixOS, home-manager, flakes, and Nix packaging. Use when writing or debugging Nix expressions, configuring NixOS or home-manager, authoring derivations, managing flake inputs, encrypting secrets with agenix or sops-nix, or hardening a NixOS host. Also use when committing or reviewing a flake.lock or `nix flake update` result, pinning or overriding a flake input, and when reviewing or deploying a NixOS config change (especially to a remote host) before it is applied. Triggers on Nix, NixOS, nixpkgs, home-manager, flake.nix, flake.lock, nix flake update, nixos-rebuild, nix build, nix develop, devShell, derivation, overlay, agenix, and on Nix errors such as hash mismatches, infinite recursion, or evaluation failures. Advisory rather than generative: it explains, reviews, and debugs. If the repository provides its own skill for authoring host configurations, prefer that for writing config.
