- ▌ Push · atherio-danpStage, commit, and (optionally) push the current changes on the CURRENT branch, following project governance. Use ONLY when Dan explicitly asks to commit and/or push.
- ▌ Onboard · atherio-danpProduce a structured "get up to speed on this whole project" orientation — vision, architecture, where things live, conventions, how to do common tasks, current state — grounded in the real code/config with pointers. Optionally writes/updates docs/ONBOARDING.md. Use when asked to onboard, give a project overview, or "how does this project work / where do I start". Read-only except the optional doc write.
- ▌ MCP Csharp · atherio-danpCreate, debug, test, and publish MCP (Model Context Protocol) servers in C# using the official ModelContextProtocol SDK — tools/prompts/resources, stdio vs HTTP transport, MapMcp hosting. Use when building or changing an MCP server in the .NET backend (relevant to your agentic pipeline).
- ▌ Write Tests · atherio-danpWrite and run tests for the .NET API following a plan's exact test list and our testing conventions — unit (domain/handlers) and integration (endpoint→DB), exact pass/fail/skip counts, never weakening a test. Use when adding or changing tests under apps/api/tests. Preloaded by the testing-expert agent.
- ▌ Add Endpoint · atherio-danpAdd a Minimal API endpoint (a feature/use case) to the .NET API — feature folder, IEndpoint self-registration, contract validation, Kommand dispatch, Result→ProblemDetails. Use when adding or changing an HTTP endpoint under apps/api/{{ProjectName}}.Api.
- ▌ Cqrs Kommand · atherio-danp bundleAuthor a CQRS command or query in the {{ProductName}} backend using the Kommand library, the three-scope validation model, and the Result<T> failure pattern. Use whenever creating or modifying a command/query/handler/validator in apps/api/{{ProjectName}}.Application, or wiring its endpoint in {{ProjectName}}.Api.
- ▌ Run Impl Loop · atherio-danp> **Serena MCP is mandatory for code (read-only here).** First call `mcp__serena__initial_instructions` to load the Serena tool manual, then use Serena for ALL code reading / searching / navigation — prefer symbol navigation (`get_symbols_overview` / `find_symbol` / `find_referencing_symbols`) over whole-file reads. (This skill mostly delegates to workflows/agents.)
- ▌ Query Postgres · atherio-danpRun read-only SQL against the {{ProductName}} PostgreSQL database to investigate or verify data during diagnosis. Use when asked to query the database directly or check actual data behind an issue. Preloaded by the rca-investigator agent.
- ▌ Result Pattern · atherio-danpImplement or use our Result<T> failure model in the .NET API — return Result from handlers, build Error values, compose with Map/Then/Match, catch domain exceptions into Result, and map Result→RFC 9457 ProblemDetails. Use when adding an operation that can fail or wiring an endpoint's error contract.
- ▌ Dotnet AI Stack · atherio-danpChoose and wire AI features in the .NET backend — LLM calls, agentic tool-calling/multi-step workflows, RAG/vector search, structured output, streaming. Use when adding or changing anything that talks to a model or orchestrates agents (your agentic pipeline). Tailored to our LLM provider + MAF + pgvector stack.
- ▌ Efcore Patterns · atherio-danpAdd or change EF Core (Npgsql/PostgreSQL) persistence in the .NET backend — entities, EF configurations, repositories, queries, migrations. Use when adding a table/entity, a query, a repository, or a migration under apps/api.
- ▌ Query Telemetry · atherio-danpQuery the {{ProductName}} observability stack (OTLP → Grafana/Loki/Tempo/Prometheus) for logs, traces, and metrics during diagnosis. Use when investigating an issue via telemetry — errors, latency, request traces, custom metrics. Preloaded by the rca-investigator agent.
- ▌ Explain Codebase · atherio-danpExplain how a specific area / file / feature / topic actually works — grounded line-by-line in the real code, with file:line citations. Use when asked to explain, trace, or understand a part of the code (e.g. "explain the model router", "how does the agentic pipeline work", "trace what CreateProject does"). Read-only; documentarian, not critic.
- ▌ Security Backend · atherio-danp bundleAudit the .NET backend (apps/api) for security issues against OWASP Top 10 mapped to .NET/Minimal API/EF Core (Npgsql), plus tenant isolation, secret handling, and EU data residency. Use when reviewing backend changes for security, or running a backend security audit. Preloaded by the security-auditor-backend agent.
- ▌ Add Domain Entity · atherio-danpAdd a domain entity, aggregate, or value object to the .NET API — rich mutable class with private ctor + static factory (UUIDv7), invariants that throw, tenant_id, identity equality; records for value objects. Use when modeling new domain state under apps/api/{{ProjectName}}.Domain.
- ▌ Microbenchmarking · atherio-danpCreate, run, configure, and interpret BenchmarkDotNet microbenchmarks in the .NET API — measure and compare approaches, runtime configs, or package versions. Use when proving a performance change, comparing implementations, or validating a hot-path optimization. (Not for profiling or load testing.)
- ▌ Validation Scopes · atherio-danpPlace validation in the correct one of our three scopes in the .NET API — API contract (no DB), Application business via Kommand IValidator, or Domain invariants that throw. Use when adding any validation/guard, or deciding where a check belongs.
- ▌ Otel Instrumentation · atherio-danpAdd or change OpenTelemetry tracing, metrics, and structured logging in the .NET API (apps/api) — OTLP exporter setup, custom ActivitySource spans, IMeterFactory metrics, log/trace correlation. Use when adding observability, custom spans/metrics, or troubleshooting distributed traces.
- ▌ Efcore Query Performance · atherio-danpOptimize EF Core (Npgsql/PostgreSQL) queries in the .NET API — fix N+1, choose tracking modes, use compiled queries, split queries, and avoid translation traps. Use when a query is slow, emits excessive SQL, or causes high DB load. Complements the efcore-patterns scaffolding skill.
- ▌ Dotnet Performance Review · atherio-danpScan .NET/C# code for performance anti-patterns (async, memory/strings, collections/LINQ, regex, serialization, I/O) with tiered severity, reporting findings without editing. Use when auditing hot paths, reviewing allocation-heavy code, or analyzing the API for optimization opportunities.
