# Loom Skills > Loads a catalogued loom domain skill on demand; the argument is the full skill name, e.g. loom-rust, or omit it to browse the catalog table below. - Skill: `cosmix/loom-skills-2` (Agent Skill) - Install (CLI): `npx skillmds@latest add cosmix/loom-skills-2` - Raw SKILL.md: https://api.skillmd.com/api/skills/cosmix/loom-skills-2/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: cosmix (https://skillmd.com/u/cosmix) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/cosmix/loom-skills-2 --- # Loom Skills Catalog Loader ## Overview Nine loom mechanics skills stay installed into `~/.codex/skills/`, indexed by Codex with their `description:` kept resident in every request. The other fifty-three domain skills install instead into `~/.codex/loom-skill-catalog//SKILL.md` — a directory Codex does not scan, so they cost nothing resident. This skill is the bridge: it loads one of those catalogued skills on demand. ## How to Load Invoked with an argument, read `~/.codex/loom-skill-catalog//SKILL.md` in full with `cat` or, for a long file, with `sed -n ',p'`, then follow it as if it had been loaded directly. The argument is the full skill name, for example `loom-rust`. **Several names may be passed at once**, separated by whitespace or commas, for example `loom-ci-cd loom-rust`. Split the argument and load EACH name by the rules below, in the order given. Never treat the whole string as one skill name — `~/.codex/loom-skill-catalog/loom-ci-cd loom-rust/SKILL.md` is not a path that can exist, and reporting it as a missing catalog is wrong. If a name's path does not exist, try `~/.codex/skills//SKILL.md` — an install made with `--skills all` keeps every skill in the indexed directory and has no catalog directory at all. If neither path exists for a name, say which name did not resolve and continue with the ones that did. Report the catalog as not installed ONLY when `~/.codex/loom-skill-catalog/` is itself absent AND the name is missing from `~/.codex/skills/` — a single unresolved name means a bad name, not a broken install. Invoked with no argument, show the table below and pick the skill that fits the task. ## Catalog | Skill | Summary | | --- | --- | | `loom-accessibility` | Web accessibility, WCAG compliance, inclusive design | | `loom-api-design` | Designs REST/GraphQL/RPC APIs for consistency and scale | | `loom-api-documentation` | OpenAPI/Swagger docs, auth flows, SDK guides | | `loom-argocd` | GitOps CD for Kubernetes with Argo CD | | `loom-auth` | OAuth2/JWT/RBAC auth patterns, sessions, MFA | | `loom-background-jobs` | Job queues, scheduled jobs, worker pools, retries | | `loom-caching` | Caching strategies: cache-aside, TTL, stampede prevention | | `loom-ci-cd` | CI/CD pipelines across GitHub Actions, GitLab, Jenkins | | `loom-code-migration` | Safe code migrations, framework upgrades, codemods | | `loom-concurrency` | Concurrency/async patterns across Rust, Python, TS, Go | | `loom-crossplane` | Crossplane infra-as-code on Kubernetes APIs | | `loom-database-design` | Schema/data model design: relational, NoSQL, warehouse | | `loom-data-validation` | Schema validation, input sanitization, output encoding | | `loom-data-visualization` | Charts, dashboards, and reports across domains | | `loom-dependency-scan` | Scans dependencies for CVEs, license issues, SBOM | | `loom-diagramming` | Mermaid diagrams: architecture, sequence, ERD, C4 | | `loom-docker` | Dockerfiles, compose, multi-stage builds, hardening | | `loom-documentation` | READMEs, architecture docs, changelogs, ADRs | | `loom-e2e-testing` | E2E testing with Playwright, Cypress, Selenium | | `loom-error-handling` | Error handling: Result/Option, retries, circuit breakers | | `loom-event-driven` | Event-driven: queues, pub/sub, event sourcing, sagas | | `loom-feature-flags` | Feature flags: rollouts, A/B tests, kill switches | | `loom-fluxcd` | GitOps CD for Kubernetes with Flux CD | | `loom-git-workflow` | Git branching, commits, merges, conflict resolution | | `loom-golang` | Idiomatic Go: goroutines, channels, testing, modules | | `loom-grafana` | Grafana dashboards, panels, LogQL/TraceQL queries | | `loom-i18n` | i18n/l10n: translations, locale formatting, RTL | | `loom-istio` | Istio service mesh: mTLS, routing, canary, Envoy | | `loom-karpenter` | Karpenter node autoscaling and cost optimization | | `loom-kubernetes` | K8s manifests, Helm, RBAC, operators, troubleshooting | | `loom-kustomize` | Kustomize overlays, patches, ConfigMap/Secret gen | | `loom-logging-observability` | Structured logging, tracing, metrics, alerting | | `loom-model-evaluation` | ML model evaluation: metrics, CV, drift monitoring | | `loom-performance-testing` | Load/perf testing with k6, locust, JMeter, Gatling | | `loom-prometheus` | PromQL, scrape configs, alerting/recording rules | | `loom-prompt-engineering` | LLM prompt design: few-shot, security | | `loom-python` | Idiomatic Python: FastAPI, Django, pandas, pytest | | `loom-rate-limiting` | Rate limiting: token/leaky bucket, quotas, Redis | | `loom-react` | React 19+ SPAs: hooks, Jotai, routing, Bun/Vite/Oxc | | `loom-refactoring` | Restructures code without changing behavior | | `loom-rust` | Idiomatic Rust: ownership, async/tokio, cargo, serde | | `loom-search` | Full-text search: Elasticsearch, OpenSearch, Meilisearch | | `loom-security-audit` | Deep security audits: OWASP, compliance, hardening | | `loom-security-scan` | Quick security checks: secrets, deps, containers | | `loom-serialization` | Serialization: JSON, YAML, protobuf, schema evolution | | `loom-sql-optimization` | SQL query optimization, indexing, EXPLAIN analysis | | `loom-technical-writing` | Technical writing: READMEs, guides, changelogs | | `loom-terraform` | Terraform/OpenTofu IaC, modules, state, workspaces | | `loom-testing` | Test implementation: unit, integration, e2e, TDD/BDD | | `loom-test-strategy` | Test strategy: pyramid, coverage, flaky diagnosis | | `loom-threat-model` | Threat modeling: STRIDE, DREAD, PASTA, attack trees | | `loom-typescript` | Type-safe TypeScript: generics, strict mode, zod/trpc | | `loom-webhooks` | Webhooks: HMAC verification, retries, idempotency | ## Note The catalogued file is the complete skill, not a summary of it — reading it is equivalent to having loaded the skill directly.
