Scale PubNub applications for high-volume real-time events

OpenTelemetry Collector deployment, configuration, and troubleshooting for Coralogix users. Use when writing or debugging collector configs — the `coralogix` exporter (`domain:` vs `endpoint:`, `${env:CORALOGIX_PRIVATE_KEY}` bracket syntax, `coralogix/resource_catalog` variant), the universal processor chain, agent → cluster-collector → gateway topology, spanmetrics/tail_sampling/k8sattributes placement, component stability checks, data-safety/redaction routing including `url_sanitizer`, `sanitize_span_name`, `allow_all_keys`, and before/after validation for broad sanitizer over-sanitization, spanmetrics cardinality protection, and Coralogix-specific presets. Covers the `otel-integration` Helm chart (EKS/GKE/AKS/ OpenShift, GKE Autopilot Warden, EKS Fargate), ECS EC2 daemonset, ECS Fargate sidecar, Linux/Windows/macOS standalone, Docker, and the universal installer. Not for OTTL authoring (use the `opentelemetry-ottl` skill) or OpAMP supervisor/Fleet Manager internals beyond the config-precedence callout.

Instruments Java, Python, Node.js, .NET, and Go applications with OpenTelemetry SDKs to send traces, metrics, and logs to Coralogix. Use for SDK-side OTel setup, OTLP exporter env vars, Coralogix resource attributes, APM transaction samplers, Kubernetes Operator injection, or debugging missing traces, metrics, logs, or no telemetry from an application. Not for OTel Collector config (use opentelemetry-collector), OTTL authoring (use opentelemetry-ottl), eBPF instrumentation, or Lambda layers.

OpenTelemetry Transformation Language (OTTL) for OTel Collector pipelines. Use when writing or debugging OTTL statements in the transform processor, filter processor, or routing connector in any collector configuration — context selection, path expression mistakes (`attributes` vs `resource.attributes`), `error_mode`, cardinality reduction with `keep_keys`, JSON body handling with `ParseJSON`, PII redaction with `SHA256` / `replace_pattern`, and span naming. Not for receiver/exporter connectivity, DNS, pipeline wiring, or telemetry that never reaches the processor — those are infra problems, not OTTL problems.

Write correct Django tests that avoid common pitfalls. Covers TestCase vs TransactionTestCase, setUp vs setUpTestData, factory-boy patterns, assertNumQueries, mock.patch placement, override_settings, file upload testing, management command testing, and DRF APITestCase. Use when writing or reviewing Django test suites.

Security essentials for Django — CSRF, CORS, security middleware, ALLOWED_HOSTS, secrets management, and common misconfigurations. Use when building or reviewing Django apps before production deployment, or when a security audit flags issues.

Use when work needs to be handed off to another agent or another human. Produce a continuation-ready brief with the objective, completed work, assumptions, unresolved issues, and next action instead of a generic summary. Good triggers include "prepare a handoff", "make this resumable", and "summarize this for another agent".

Audits an already-written use case (UC-XXX) or test case (TC-XXX) against its specification and reports a coverage matrix: which main success scenario steps, alternative flows, business rules, preconditions, and postconditions have code and tests behind them, which are still open, and which code or tests have drifted away from the specification. Use when the user asks to "check coverage", "run a coverage check", "is UC-001 fully implemented", "is UC-001 completely tested", "audit the use case", "show me the coverage matrix", "do a traceability check", "what is still missing for UC-001", or "can I set the status to Tested". This is specification coverage, not line coverage from a coverage report. It reports only — it writes no code, no tests, and no files. When the user wants the gaps closed rather than listed, use /implement, /spring-boot-test, /vitest-test, or /playwright-test instead.

Creates versioned Flyway database migration scripts (V*.sql) with sequences, tables, constraints, and foreign keys from the entity model. Use when the user asks to "create a migration", "generate SQL scripts", "set up database tables", "write a Flyway migration", or mentions schema migration, DB migration, database versioning, or SQL migration files.

Implements use cases across a Spring Boot + Spring Data JPA backend (flat single-module or hexagonal/ports-and-adapters multi-module) and an Angular frontend wired to that API. Use when the user asks to "implement a use case", "build the API", "create a REST endpoint", "write the data access layer", "build the Angular page/component", or mentions Spring Boot, JPA/Hibernate entities, hexagonal architecture, ports and adapters, or an Angular frontend calling a Java backend.

Scaffold the good-oss-citizen contribution gate into a consumer repository: a `pull_request_target` GitHub Actions check that fails any pull request whose description lacks a contribution declaration — an "AI Disclosure" section or an explicit "no AI assistance" statement — plus the vendored detection script, a PR template, and the tessl.json dependency entry. The gate enforces an outcome (AI use is disclosed) on the PR side, where it cannot be bypassed; it does not, and cannot, prove a tool ran. Use when a maintainer wants to add, install, set up, scaffold, enable, or wire up a contribution gate / a PR check that requires good-oss-citizen or AI-use disclosure before contributing.

Runs a structured 10-check pre-submission checklist against an open-source contribution before the contributor opens a pull request. Use when the user has written code for an open-source project and needs to prepare a PR, submit a contribution, or verify readiness. Triggers on "submit a PR", "open a pull request", "prepare the contribution", "ready to merge", "check my pull request". IMPORTANT — run this AFTER code is written but BEFORE submission. Checks: AI policy compliance and disclosure (including voluntary disclosure when no policy exists), diff size and focus, PR template, code style, commit conventions, tests, changelog and metadata, legal requirements (DCO/CLA), agent artifacts, slop detector patterns, and human ownership verification.

Analyzes project contribution guidelines, identifies the right venue (pull request, issue, discussion, RFC/KEP/DEP), checks issue metadata (claims, assignments, labels), searches for prior rejected attempts, and drafts proposals formatted to project templates. Use when the user wants to contribute to an open-source project, fix a bug, submit a PR, improve or refactor code, asks where to submit a change, or needs help choosing between PR/issue/discussion/RFC. Triggers on "fix this issue", "submit a PR", "refactor this", "improve this code", "open a pull request". IMPORTANT — run this AFTER recon and BEFORE writing code to verify the right venue and check for prior attempts.

Django patterns -- custom user model, project structure, models, views, URL routing, select_related/prefetch_related, signals vs save(), middleware, settings splitting, custom managers, management commands, and migrations. Use when building or reviewing Django apps, setting up a new Django project, or choosing between Django patterns.

Converts a PRD or requirements document into a structured, phased implementation plan with individual phase files and granular per-task files written to .context/plans/. Also restructures existing monolithic planning documents into digestible, hierarchical directory structures. Creates a root plan index summarising all phases, a numbered phase file per phase, and a numbered task file per task inside each phase directory. Use when the user asks to create an implementation plan, break down a PRD, convert requirements to tasks, structure project phases, generate a roadmap, plan a project in sprints, organise task breakdown, split a monolithic planning doc, or decompose a spec into phases and tasks.

Creates or updates BPMN 2.0 business process models (docs/processes/BP-XXX-*.bpmn) from the requirements catalog and the use case diagram: one pool per process, one lane per actor, every activity one use case, gateways for the decisions between them, and a diagram layout a modeler such as bpmn.io can open. Every process gets a BP-XXX id for communication and traceability; run it with that id (e.g. /business-process BP-001) to update one process. Use when the user asks to "model the business process", "create a BPMN", "draw the process", "connect the use cases into a process", "update BP-001", or mentions a business process, process model, BPMN, swimlanes, or a .bpmn file. Also trigger when a review or the use case skills report a summary use case whose parts hand over to another role, wait for an event or deadline, or run in parallel — that flow is a business process. The resulting model is what /test-case BP-XXX derives end-to-end test cases from.

Creates entity model documents with Mermaid.js ER diagrams and attribute tables defining entities, relationships, data types, and validation rules. Use when the user asks to "create an entity model", "design a data model", "draw an ERD", "define database schema", "model entities", or mentions entity-relationship diagram, ER diagram, database design, or data modeling. Also trigger whenever the task is to produce, write, or design an entity model or data model document (e.g. docs/entity_model.md) from a requirements catalog — including phrasings like "data model design", "the team needs an entity model before development", or a request to document entities with attributes, data types, precision, and validation or cross-attribute constraints.

Gathers, organizes, and documents software requirements into structured catalogs with functional requirements (user stories), non-functional requirements (measurable quality attributes), and constraints. Use when the user asks to "write requirements", "create a PRD", "gather requirements", "document feature specs", "write user stories", "define NFRs", "list constraints", "write a glossary", "define domain terms", or mentions requirements catalog, requirements analysis, product requirements document, feature specification, or glossary.
