svelte-code-writersveltejs11KCLI tools for Svelte 5 documentation lookup and code analysis. MUST be used whenever creating, editing or analyzing any Svelte component (.svelte) or Svelte module (.svelte.ts/.svelte.js). If possible, this skill should be executed within the svelte-file-editor agent for optimal results.grounding-before-codingriekelt11KUse when starting any non-trivial change, investigating a bug, or working in unfamiliar code - before the first line is written. Also use for pure investigation with no change planned yet - \"dig into this\", \"figure out why\", \"sometimes the export is empty\", intermittent errors after a deploy. Encodes the ground-first discipline: map the real code and data, quote evidence, never guess conventions. Use whenever a change or a conclusion is about to be built from belief instead of from the treguarding-architectureriekelt11KUse when a change crosses module boundaries, adds a dependency direction between modules, touches a critical path, or conflicts with a stated principle - and when writing or updating architecture principles themselves. Encodes structural invariants as named, enforced contracts: statement, rationale, guard. Use whenever \"we'll just import it from there for now\" appears, which is how boundaries die.testing-changesriekelt11KUse when deciding what tests a change needs - a feature, a bug fix, a refactor, any behavior change - or when reviewing whether a diff's tests are sufficient. Encodes tests-change-with-behavior, the bug-regression pattern, and assertion discrimination. Use whenever behavior changes and the test diff is empty, especially when the change is "too small to test".keeping-one-source-of-truthriekelt11KUse when adding data, config, state, constants, an enum-like string, a cache, or anything that could exist in two places - or when two sources already disagree. Encodes the one-fact-one-source doctrine for code and data: derive rather than store, extend the owner, absorb duplicates. Use at the moment copying a value feels faster than referencing it.agent-email-inboxresend11KUse when building any system where email content triggers actions — AI agent inboxes, automated support handlers, email-to-task pipelines, or any workflow processing untrusted inbound email. Always use this skill when the user wants to receive emails and act on them programmatically, even if they don't mention "agent" — the skill contains critical security patterns (sender allowlists, content filtering, sandboxed processing) that prevent untrusted email from controlling your system.scoping-changesriekelt11KUse when deciding how big a fix should be, when scope is drifting mid-task, when a plan is being quietly trimmed to fit, or when "while you're at it" appears in any form. Encodes size-to-trigger, decompose-not-descope, and drive-to-completion. Use whenever the work is about to grow past its cause or shrink below its promise.corevercel-labs11KCore package for defining schemas, catalogs, and AI prompt generation for json-render. Use when working with @json-render/core, defining schemas, creating catalogs, or building JSON specs for UI/video generation.operating-safelyriekelt11KUse when an action touches live systems, shared state, or things that do not come back - deleting, overwriting, restarting, killing processes, editing shared config, handling secrets, or working beside concurrent sessions. Encodes the destructive-op guards, secrets hygiene, and concurrent-session safety. Use before the destructive command, not after, even when the command looks routine.handling-failuresriekelt11KUse when writing or touching any error path, catch block, fallback, default value, retry, or degraded mode - in any language, any repo. Encodes the no-silent-swallows contract and the fail-loud discipline. Use whenever an exception is about to be caught, a null is about to get a default, or a failure could pass unnoticed, even if the goal is "just make it not crash".adding-dependenciesriekelt11KUse when about to add, update, vet, or remove a dependency - a package, library, SDK, GitHub action, base image, or vendored code - or when a project's dependency posture needs declaring. Encodes the exhaust-what-you-have ladder, the vetting questions, and pin-and-prove updating. Use even for a tiny utility package: that is exactly how the tree grows.marimo-pairmarimo-team11KDrive a live marimo notebook as a workspace: run Python in the same kernel the user does, inspect live notebook state, and commit durable notebook changes. Use when the user wants to start a marimo notebook or pair on an active marimo session.python-resiliencewshobson11KPython resilience patterns including automatic retries, exponential backoff, timeouts, and fault-tolerant decorators. Use when adding retry logic, implementing timeouts, building fault-tolerant services, or handling transient failures.diagramming-processesriekelt11KUse when a business process, workflow, lifecycle, or interaction between systems needs a diagram - a flow that prose serializes badly, a state machine, a message sequence, an enterprise process map - or when drawing the process documentation of a legacy campaign. Encodes diagrams-as-source, the notation ladder from ArchiMate to PlantUML, the kind-per-question table, behavior-level participants, the diagram index, and the same-change maintenance rule. Use whenever a document needs a graph rather penetration-testing-with-strixusestrix11KPentest a web app, API, codebase, repository, URL, domain, or IP with Strix — autonomous AI penetration testing that exploits and proves vulnerabilities (OWASP Top 10 and beyond — injection, XSS, SSRF, auth/access-control flaws, IDOR, business logic) instead of just flagging them. Runs self-hosted with the open-source CLI or via the managed app.strix.ai cloud, and returns validated findings with proof-of-concept exploits (Markdown, JSON, CSV, SARIF). Use when the user asks to pentest, hack, secufastapifastapi11KFastAPI best practices and conventions. Use when working with FastAPI APIs, Pydantic models, dependencies, streaming responses including Server-Sent Events (SSE), and serving frontend apps.

Available APIs: Discount, Cart and Checkout Validation, Cart Transform, Pickup Point Delivery Option Generator, Delivery Customization, Fulfillment Constraints, Local Pickup Delivery Option Generator, Order Routing Location Rule, Payment Customizationgitops-workflowwshobson11KImplement GitOps workflows with ArgoCD and Flux for automated, declarative Kubernetes deployments with continuous reconciliation. Use when implementing GitOps practices, automating Kubernetes deployments, or setting up declarative infrastructure management.cost-optimizationwshobson11KOptimize cloud costs across AWS, Azure, GCP, and OCI through resource rightsizing, tagging strategies, reserved instances, and spending analysis. Use when reducing cloud expenses, analyzing infrastructure costs, or implementing cost governance policies.documenting-contractsriekelt11KUse when documenting an HTTP API, message payloads, queue contracts, DTOs, file formats, or webhooks - or when writing the api-reference of a legacy campaign, or when callers keep asking what a field means or which errors an endpoint returns. Encodes the four detail levels, the DTO-first catalog, wire types with source anchors, the generated-spec one-home rule, and omitted-versus-null semantics. Use whenever a machine interface needs documenting for its callers, even if nobody says "API docs".python-observabilitywshobson11KPython observability patterns including structured logging, metrics, and distributed tracing. Use when adding logging, implementing metrics collection, setting up tracing, or debugging production systems.scrapebrightdata11KScrape web content as clean markdown/HTML/JSON via the Bright Data CLI (`bdata scrape`). Use when the user wants to fetch a page, extract content from a list of URLs, or crawl paginated listings. Hands off to `data-feeds` for supported platforms (Amazon, LinkedIn, TikTok, Instagram, YouTube, Reddit, etc.) and to `search` when URLs must be discovered first.

Use when the user wants to run Resend commands in the shell, scripts, or CI/CD pipelines, or send/preview React Email templates. Always load this skill before running `resend` commands — it contains the non-interactive flag contract and gotchas that prevent sildarwin-skillalchaincyf11KDarwin Skill 2.0 (达尔文.skill 2.0): autonomous skill optimizer, v2.0 integrates Microsoft Research SkillLens (arXiv 2605.23899) 9-dim rubric + SkillOpt (arXiv 2605.23904) validation-gated design + human-in-the-loop checkpoints.
