Writing developer-facing prose that can be skimmed first and trusted enough to finish — READMEs, guides, tutorials, reference docs, proposals, PR descriptions, release notes. Load before drafting, rewriting, restructuring, or editing technical documents, when…
Compose installed agent skills into one orchestrated multi-agent run: an agent graph where each node is a sub-agent that loads exactly one skill, edges carry structured data, and stages fan work out, adversarially verify it, and synthesize one deliverable.…
Composable multi-agent code review of any change boundary — the working tree mid-development, a branch diff, a stacked layer, or a pull request: one orchestrator fans out sub-agents, each loading exactly one installed skill as a review lens…
Design and protect browser-facing BFF and backend HTTP entry points: an explicit public/protected access classification for every production route, a composition-prepared endpoint registrar that installs session, Origin, Fetch Metadata, CSRF, and content-type…
Design and evaluate deep modules: cohesive responsibility behind a small, stable caller-facing contract, with information hiding, justified seams, explicit effects, dependency strategy, and behavior-focused tests. Use when designing or changing an in-process…
Functional programming patterns with immutable data. Use when writing logic, data transformations, or encountering mutation bugs — including any feature request that builds, merges, filters, sorts, prices or otherwise reshapes records, lists, carts, orders or…
Observability as an engineering discipline — wide events / canonical log lines, OpenTelemetry instrumentation (traces, metrics, context propagation, sampling, Collector), SLIs/SLOs/error budgets, symptom-based alerting with burn rates, telemetry hygiene, and…
Reduce total mechanism in a selected existing system or behavior path while conserving its agreed observable behavior and non-functional guarantees. Use when the user explicitly wants fewer branches, states, dependencies, layers, flags, retries, jobs,…
