Identifies silent failures, inadequate error handling, and inappropriate fallback behavior in code. Zero tolerance for errors that occur without proper logging and user feedback. Triggers: When reviewing error handling, checking for silent failures, analyzing catch blocks. Examples: - "Review the error handling" -> audits all error handling in recent changes - "Check for silent failures" -> hunts for swallowed errors and empty catch blocks - "Analyze catch blocks in this PR" -> reviews every try-catch for adequacy - "Are there any hidden failures?" -> finds errors that get silently ignored
Install and wire markstream-vue, markstream-react, markstream-vue2, or markstream-angular into an existing repository. Use when Codex needs to choose the right package, install the smallest peer-dependency set, fix CSS/reset order, decide between `content` and `nodes`, or add a minimal working renderer example.
Keep status and error colours minimal and consistent — too many semantic colours confuse users. Each colour must mean exactly one thing. Errors should be recoverable, large failures must be prevented, and the UI should always give the user a path forward. Use when designing status indicators, error states, form validation, alerts, or any feedback system.
Generate a comprehensive, structured learning guide for any technical topic or technology. Use this skill whenever a user wants to learn a new technology, programming language, framework, tool, or concept — even if they phrase it casually (e.g., "teach me Rust", "how do I get started with Kubernetes", "I want to learn React", "help me understand GraphQL", "give me a roadmap for learning Docker"). This skill covers concept identification and categorization, weekly study schedules, local dev setup, concept explanations with examples, exercises, popular libraries, project ideas, and resources. Trigger for any "how do I learn X", "roadmap for X", "getting started with X", "study plan for X", or "teach me X" request — even if they don't explicitly ask for a guide or roadmap.
StartuPage platform help — startup ecosystem combining Stripe/LemonSqueezy/Polar/RevenueCat/Dodo-verified MRR leaderboard, founder + startup sub-page profiles, and a four-track Opportunities marketplace (hiring, fundraising Open Rounds, co-founder matching, startup acquisitions). Free plan with 2 themes and the StartuPage badge, Starter $5/mo (1 opportunity, custom domain, badge removal, 8 themes), Growth $9/mo (3 opportunities, pro analytics), Lifetime $179. Use when setting up a founder profile and choosing whether to show exact MRR / a range / private, connecting a payment provider for verified revenue, picking a pricing plan or the Lifetime Pass, posting a hiring / fundraising / co-founder / acquisition opportunity, comparing StartuPage vs TrustMRR / Indie Hackers / Peerlist / Wellfound, or climbing the Top Startups or Top Founders leaderboard. Do NOT use for cross-marketplace side-project valuation (use /sales-side-project-valuation).
Handle Word document (.docx) creation, editing, and analysis with high-fidelity visual review. Use for professional reports, legal documents, and tracked changes. Use proactively when quality and precise formatting are critical. Examples: - user: "Create a professional report in Word" -> use python-docx with render loops - user: "Draft a legal contract with redlines" -> use ooxml redlining workflow - user: "Extract text from this DOCX while preserving structure" -> use pandoc markdown conversion
Search and query the Grounded Docs MCP Server documentation index. Covers listing indexed libraries, searching documentation content, and resolving library versions. Use when you need to look up API references, find code examples, or check which documentation is available in the local index.
Cross-chain bridging, swapping, and "bridge+call" via Relay through the OpenFinance backend. Use whenever the user wants to move tokens between chains or execute a destination-chain transaction funded from another chain. Triggers: "bridge X from Y to Z", "move my USDC to Base / Arbitrum / Optimism / Polygon / Solana", "swap ETH for USDC on Base", "cross-chain swap", "bridge and call", "how do I get to Solana / back from Solana", "my USDC is stuck on Solana", EVM-to-EVM, EVM-to-Solana, Solana-to-EVM, Bitcoin bridge, gas topup on destination, native-token sentinel 0x0, relay quote/preview/execute flow, poll intent status. Covers POST /agent/relay/quote, POST /agent/relay/execute, GET /agent/relay/status. Includes the chainId cheatsheet (1/137/8453/10/42161/... and Solana 792703809 specifically), tradeType semantics (EXACT_INPUT / EXACT_OUTPUT / EXPECTED_OUTPUT), why topupGas is auto-disabled on Solana routes, the Solana wallet delegation requirement for Solana-origin execute, and bridge+call payloads (txs array). Use together with openfin-setup (API key check) and openfin-troubleshooting (Blockhash not found, Custom:101, 412 delegation).
Mod development for Space Engineers version 1. Search mod code for examples and patterns.
Generate exactly one high-quality Conventional Commit message from the current Git diff. Use when Codex needs to inspect staged changes, summarize the dominant intent, and return only the final commit message with no analysis or extra text.
Query historical search volume of Jungle Scout keywords, returning the exact search volume trend of Amazon keywords on a 7-day cycle, covering 10 marketplaces including the US, UK, Germany, Japan, etc. This skill is triggered when users mention keyword search volume trends, historical search volume, changes in search popularity, keyword seasonality, search volume fluctuations, Jungle Scout search volume, keyword search volume history, keyword trend, search volume over time, seasonal search volume, keyword popularity trend. Even if users do not explicitly mention "Jungle Scout", this skill should be triggered as long as their needs involve viewing the search volume change trend of a certain Amazon keyword over a period of time.
Use GitHits CLI for canonical open-source examples, indexed source, docs, grep, file listing, and code navigation. Activate when verifying library behavior from source or examples. For metadata, vulnerabilities, dependency graphs, or changelogs, use githits-package instead.
