Skills for Backend and APIs

Skills for Backend and APIs: what each one does, an install command and example prompts.

convex-deploy-guard convex skill Classifies and announces the target Convex deployment before running mutations. Requires explicit approval for production and enforces read-only session modes. CX Codex +1 36,000installs convex-design convex skill This skill designs Convex backends from product requests, covering schemas, functions, auth, files, and LLM workflows. Use it for new or existing Convex projects. CX Codex +1 36,000installs convex-reviewer convex skill Walks Convex code through auth, validator, index and reactivity checks. Useful before you ship backend functions. CX Codex +1 36,100installs convex-docs convex skill Pins the project's installed Convex version and fetches current markdown docs or checks types instead of generating outdated API calls. CX Codex +1 36,100installs convex-add convex skill Adds hosting or another backend capability to the current Convex app. Use it when you want an agent to locate and wire a requested component. CX Codex +1 35,900installs convex-advisor convex skill Reads a Convex deployment's 72h insights, root-causes each event in code, and reports fixes ranked by severity. CX Codex +1 35,900installs convex-crons convex skill Adds recurring scheduled jobs to Convex applications. Useful when you need to schedule backend maintenance and periodic cleanups. CX Codex +1 36,000installs convex-env convex skill This skill sets and wires Convex deployment environment variables and secrets. Use it when actions need deployment-specific values without putting secrets in code. CX Codex +1 36,000installs convex-seed convex skill Populates Convex database tables with sample rows or imports external datasets. Useful when preparing dev environments without manual data entry. CX Codex +1 35,800installs convex-verify convex skill convex-verify tests a Convex feature with seeded data, multiple mocked identities, and negative authorization checks. Use it for a specific feature you have built or changed. CX Codex +1 35,800installs convex-monitor convex skill This skill blocks on the next event in a Convex app — a dev error, a prod error or a feature request — and hands it to the agent. CX Codex +1 35,800installs convex-billing convex skill Adds Stripe payments and subscriptions to a Convex app using @convex-dev/stripe with checkout sessions, webhooks, and subscription gating. CX Codex +1 35,800installs convex-launch-readiness convex skill Runs four Convex audits into one readiness report with a score and an ordered fix plan. Useful when the backend is about to ship and you need to know what to fix first. CX Codex +1 35,900installs convex-explain-app convex skill Maps an existing Convex backend using schema and exported functions. It helps you understand data models, public APIs, and auth before making changes. CX Codex +1 35,900installs convex-backup convex skill Sets up Convex snapshot exports and runs a restore drill into a throwaway preview, so you find out whether recovery actually works. CX Codex +1 35,900installs convex-cost convex skill Analyzes Convex deployment spend, ranks functions driving read costs, and projects growth curves. Points out the cheapest code fix for each bottleneck. CX Codex +1 35,900installs convex-insights convex skill Queries logs and health for a running Convex deployment in natural language. Use it to investigate failures or check whether errors began after a deployment. CX Codex +1 35,900installs convex-agent convex skill Adds an AI agent backend to a Convex app: durable threads, message history, tool calls and vector search for RAG. CX Codex +1 35,900installs convex-test convex skill Generates deterministic vitest tests for Convex backend functions using convex-test. Runs against an in-memory backend without live deployments. CX Codex +1 35,900installs convex-sentinel convex skill Configures Sentinel error capture inside your own Convex deployment. Useful for tracking server failures and client React crashes without sending logs to third-party services. CX Codex +1 35,700installs convex-self-heal convex skill The skill takes a production error through triage, root cause and repair, certifies the fix on a preview, then opens a PR. A human merges. CX Codex +1 35,800installs convex-suggest convex skill The skill notices when you hand-roll something a ready Convex component already solves, and offers one match after your task is done. CX Codex +1 35,800installs exploiting-api-injection-vulnerabilities mahipal skill Audits API parameters, headers, and request bodies for injection flaws like SQLi and SSRF. Helps assess backend input validation against OWASP API standards. CX Codex +1 311installs domain-fintech actionbook skill A skill that gives the agent fintech domain rules for Rust: decimal money, immutable transactions, audit trails. Useful when you build payments or ledgers. CX Codex +1 2,800installs domain-cloud-native actionbook skill A domain skill that injects cloud-native architecture rules into Rust projects, covering health endpoints, graceful exits, and stateless design. CX Codex +1 2,900installs post-purchase-upsell-flow autonnel skill Designs one-click post-purchase upsells and downsells that boost average order value without lowering base checkout conversion. Covers offer structure and technical payment flows. CX Codex +1 103,100installs connect-required-verification-information stripe skill Guides the agent through Stripe Connect verification rules to determine KYC requirements, onboarding fields, and documents for connected accounts. CX Codex +1 1,400installs convex waynesutton skill Routes Convex backend tasks to dedicated builder skills and enforces global rules for queries, mutations, and schemas. Useful as the starting point for any Convex project. CX Codex +1 5,700installs performance-profiler Alireza Rezvani skill This skill investigates CPU, memory, I/O, and database bottlenecks in Node.js, Python, and Go apps. Use it when tracking down a slow endpoint or rising memory use. 720installs power-platform-architect official Tim Hanewich skill This skill turns business requirements, use cases, and meeting transcripts into a Power Platform solution architecture with component choices and Mermaid.js diagrams. 205installs rust-router actionbook skill A skill that stops the agent from answering Rust questions off the cuff and walks it through layers instead: language mechanics, design choices, domain constraints. CX Codex +1 2,700installs domain-iot actionbook skill This skill turns IoT constraints into Rust design choices: the network drops, power is scarce, the device is physically reachable. It steers the agent toward buffering, retries and TLS. CX Codex +1 2,700installs platform-apex-generate forcedotcom skill Generates Apex classes and triggers, then runs the code analyzer and org tests. Useful when a Salesforce codebase keeps growing. CX Codex +1 7,100installs design-code-architecture wondelai skill Walks you from an app idea to a deliberate architecture: eight phases, a question at every decision point, results written into docs/. Useful when you need to pick boundaries and split the domain. CX Codex +1 2,300installs platform-apex-test-generate forcedotcom skill This skill writes and fixes Apex test classes: data factories, bulk runs, mocks and coverage analysis. Useful when a deploy stalls on missing coverage. CX Codex +1 7,000installs replica-architect Jakeschincariol skill Plans the stack, database schema and API routes for an app clone, working from the recon map replica-recon produced. Useful once recon is done and you need a build plan. CX Codex +1 618installs database-schema-designer Alireza Rezvani skill This skill turns database requirements into relational schemas, ERDs, and migrations. Use it when planning tables for a feature or reviewing an existing design. 692installs platform-apex-test-run forcedotcom skill Runs Apex tests via the Salesforce CLI, analyzes code coverage, and guides test-fix loops. Useful when investigating unit test failures or low coverage. CX Codex +1 6,900installs replica-backend Jakeschincariol skill Builds the backend of an app clone: auth, database migrations and access rules, Stripe payments, email and background jobs. Reads replica/architecture.md and keeps a checklist in replica/backend.md. CX Codex +1 613installs xurl xdevplatform skill CLI skill for authenticated X API requests. Lets agents post updates, inspect timelines, and manage direct messages. CX Codex +1 660installs
