React composition patterns that scale. Avoid boolean prop proliferation by using compound components, lifting state, and composing internals. Use when refactoring components with boolean prop proliferation, building flexible component libraries, or during architecture review. Skip for simple components with 1-2 props…

Applying or switching a repository's license (Apache 2.0, Elastic License v2, or Proprietary): rewrites the LICENSE file, updates Go/TS source headers, sets SPDX identifiers, and validates consistency after user confirmation. Use when asked to set, apply, or switch a license, or when scaffolding a service with no…

Auditing a dependency for supply-chain risk before install (pip/npm/go/cargo): checks typosquatting, maintainer/age risk, vulnerability DBs (OSV, GHSA, Socket), and lockfile hash pinning, then emits a risk score and approve/conditional/escalate/block decision. Use when adding or updating a dependency, reviewing a…
Skill Claude CodeCodex
Checking frontend quality against changed UI via ring:qa-frontend in accessibility, visual, e2e, or performance mode and aggregating pass/fail verdicts. Use when a frontend change needs standalone a11y, visual-snapshot, Playwright e2e, or Lighthouse/Core-Web-Vitals validation outside the dev cycle. Skip for…

Creating Helm charts to Lerian conventions via ring:helm: standardized chart structure, full env-var coverage from .env.example, security defaults (runAsNonRoot, readOnlyRootFilesystem), ClusterIP-only services, and health probes; validates helm lint and template render. Use when creating, modifying, or reviewing a…

Interactively authoring an access-manager permission-declaration manifest (permissions.yaml) for the access-manager "inversão de responsabilidade": drives a plugin team through discovering its real Authorize() surface, normalizing every action to the SEMANTIC standard (never HTTP verbs), declaring roles/group grants…
Skill Claude CodeCodex
Detecting goroutine leaks in Go: greps for goroutine patterns, audits goleak coverage (VerifyTestMain/VerifyNone), runs goleak, and dispatches ring:backend-go to fix leaks and add regression tests. Use after implementation or during review when code spawns goroutines or a leak is suspected. Runs before…

Generating or auditing a repository's llms.txt per the llmstxt.org spec, and creating CLAUDE.md / AGENTS.md when missing, by analyzing README, build files, docs, and API surface. Use when creating an llms.txt, auditing an existing one for spec compliance and live links, or improving a repo's AI readability. Skip when…

Hardening Dockerfiles to reach Docker Hub Health Score grade A: enforcing a non-root USER, minimal/distroless multi-stage base images, no fixable critical/high CVEs, no AGPL-3.0 deps, and SBOM+provenance attestations. Use when creating a new Dockerfile, auditing one for security, or preparing images for Docker Hub…
Skill Claude CodeCodex
Implementing the canonical /readyz readiness-probe contract across Go, TypeScript, and Next.js via a 12-gate cycle: detects stack, audits compliance, then dispatches agents to build the dependency probe, url.Parse TLS detection, ValidateSaaSTLS enforcement, metrics, startup self-probe, and graceful drain, then runs…
Skill Claude CodeCodex
Implementing a single planned task (Task N.M.T) end-to-end: selects the right backend agent by language and service type, drives one TDD RED->GREEN turn, then verifies coverage, lint, license headers, runtime, and delivery before handoff. Runs as Gate 0 before ring:reviewing-code. Use to drive ONE task inside an…
Skill Claude CodeCodex
Instrumenting streaming events: wires lib-streaming event emission end-to-end into a Lerian Go service via a 13-gate cycle (catalog, Builder bootstrap, Emit sites, outbox, HTTP manifest, NoopEmitter fallback, integration and chaos tests), dispatching ring:backend-go under TDD. Consumes the validated…
Skill Claude CodeCodex
Managing an in-progress development cycle without driving it: status reports phase, epic/gate progress, assertiveness, and elapsed time from current-cycle.json; cancel confirms, marks the cycle cancelled, and writes a partial feedback report. Use when checking the status of, or cancelling, a running dev cycle. Skip…
Skill Claude CodeCodex
Mapping a Go service's Service -> Module -> Resource hierarchy for dispatch-layer registration: detects modules and per-module PostgreSQL/MongoDB/RabbitMQ resources, database names, and shared databases, generates MongoDB index migration pairs (.up.json/.down.json), detects existing Postgres migrations, emits an HTML…
Skill Claude CodeCodex
Migrating a Lerian Go app off lib-commons observability imports (deprecated shims or removed APIs) to lib-observability via a fixed mapping table, then bumps go.mod and validates the build; ring:backend-go applies the edits. Covers log/zap/runtime/assert, opentelemetry/tracing, HTTP middleware, context helpers, and…
Skill Claude CodeCodex
Migrating Lerian Go services from .env/YAML operational knobs (log levels, feature flags, rate limits, timeouts) to the lib-systemplane hot-reloadable runtime config client, wiring the migration-only make systemplane-ddl pipeline (runtime DDL forbidden in v1.6.0+). Orchestrates an 11-gate cycle dispatching…
Skill Claude CodeCodex
Planning a backend refactor: audits an existing Go or TypeScript backend against Ring/Lerian standards and produces a prioritized task list (findings.md + tasks.md) ready for ring:running-dev-cycle. Plans only — no edits. Use when an existing backend service needs to meet standards or an audit is requested. Skip for…
Skill Claude CodeCodex
Planning a whole-codebase simplification: audits a Go/TS codebase for needless abstraction and emits a KILL/REVIEW/KEEP plan plus a ring:running-dev-cycle task array. Plans only — no edits. Detects single-impl interfaces, pass-through shims, translation-free adapters, and dead-code cascade chains under an inverted…
Skill Claude CodeCodex
Planning a frontend refactor: audits an existing React/Next.js frontend against Ring standards (architecture, design system, accessibility, testing) and produces a prioritized task list (findings.md + tasks.md) for ring:running-dev-cycle-frontend. Plans only — no edits. Use when an existing frontend needs to meet…
Skill Claude CodeCodex
Reviewing a Go/TS service's operational risk by mapping integration failure points (external HTTP calls, queue consumers, outbound webhooks), simulating stuck intermediate states for each entity in a flow, and classifying each scenario into tiers — then emitting operational runbooks (Tier 2) or gap specs (Tier 3). Two…

Running the frontend (React/Next.js/TS) dev cycle from a plan.md (ring:writing-plans format; legacy tasks.md only for in-flight cycles) or backend handoff: drives frontend agents through Gate 0 TDD plus accessibility/visual/E2E/perf checks, Gate 7 parallel review, and Gate 8 user validation, with rolling-wave phase…
Skill Claude CodeCodex
Running the backend dev cycle: implements every task in a rolling-wave plan.md (ring:writing-plans format) for a Go/TS service, driving specialist agents through Gate 0 implementation/TDD, Gate 8 parallel review, and Gate 9 validation per epic, elaborating later phases at each phase boundary. Use when starting or…

Using lib-observability/assert, Lerian's runtime assertion package, in two modes. Sweep Mode detects panic()/log.Fatal zero-panic violations, DIY invariant checks, hand-rolled domain predicates, and missing InitAssertionMetrics. Reference Mode catalogs the asserter lifecycle, domain predicates, observability trident…
