Rust mutability design: choosing between &mut , interior mutability, and thread-safe patterns. \n \n Guides decision-making for E0596, E0499, E0502 errors by asking whether mutation is necessary and who controls it, rather than reflexively adding mut \n Covers single-thread patterns (Cell, RefCell) and multi-thread patterns (Mutex, RwLock, Atomic types) with clear selection criteria \n Includes borrow rule reference, anti-patterns (RefCell overuse, Mutex in hot loops), and decision tables f

Inspect and compare feature flag states across React release channels. \n \n View all flags across channels (www, www-modern, canary, next, experimental, rn variants) or compare specific channels with --diff \n Output formats include default table view, CSV export, and cleanup status grouping \n Flag states indicated by symbols: enabled (✅), disabled (❌), variant testing (🧪), profiling-only (📊) \n Common pitfall: __VARIANT__ flags are tested in both states on www; use --diff to spot meaningful

Extract content from multiple URLs in parallel, token-efficiently. \n \n Handles webpages, articles, PDFs, and JavaScript-heavy sites with a single command \n Runs in a forked context to minimize token overhead compared to built-in WebFetch \n Supports batch extraction of multiple URLs with optional focus objectives \n Requires parallel-cli installation and authentication; outputs extracted content as markdown to a local file for follow-up queries \n

Delete a Google Calendar event and send cancellation notifications via Gmail. \n \n Requires both gws-calendar and gws-gmail skills to be loaded before execution \n Workflow: retrieve event details from calendar, delete the event with attendee notifications enabled, then send a follow-up email to attendees \n Automatically notifies all attendees when sendUpdates is set to \"all\" during event deletion \n

Batch rename multiple Google Drive files matching a search pattern to enforce consistent naming conventions. \n \n Requires the gws-drive skill and gws binary to execute \n Workflow: search for files by name pattern, update each file's name individually, and verify the changes \n Supports flexible filtering via Google Drive query syntax (e.g., name contains 'Report' ) \n Renames are applied one file at a time; suitable for small to moderate batch operations \n

Diagnose and fix failing Power Automate cloud flows through step-by-step error inspection. \n \n Requires a FlowStudio MCP server connection with valid JWT; see the flowstudio-power-automate-mcp skill for setup \n Provides a structured 8-step workflow: locate flow, find failing run, extract top-level error, read flow definition, inspect action outputs, pinpoint root cause, apply fix, and verify \n Supports fast-path diagnosis via FlowStudio for Teams subscriptions using get_store_flow_errors for

Configure Continuous Clearing Auction (CCA) smart contract parameters for fair and transparent token distribution.

Automated security scanning for agent skills before installation, detecting prompt injection, malicious code, excessive permissions, and supply chain risks. \n \n Runs static analysis via bundled Python scanner that outputs structured JSON findings with severity levels and URLs \n Validates SKILL.md frontmatter (required fields, tool justification, model overrides) and checks for config poisoning or scope creep in instructions \n Analyzes scripts for data exfiltration, reverse shells, credential

Automated version detection and migration for assistant-ui and AI SDK with breaking-change guidance. \n \n Detects current installed versions against npm ground truth and identifies which migrations are needed \n Routes updates through AI SDK v6 migration first (if required), then assistant-ui version-specific migrations, with clear dependency ordering \n Includes reference guides for AI SDK v4/v5 to v6 transitions, assistant-ui version jumps, and a breaking-changes quick reference table \n Prov
