Supports process flows, system architectures, comparisons, mindmaps, and more with built-in syntax error prevention.
security-audit
by mono
Audit SkiaSharp's native dependencies for security vulnerabilities and CVEs. Read-only investigation that produces a status report with recommendations. Use when user asks to: - Audit security issues or CVEs - Check CVE status across dependencies - Find security-related issues and their PR coverage - Get an overview of open vulnerabilities - See what security work is pending Triggers: "security audit", "audit CVEs", "CVE status", "what security issues are open", "check vulnerability status", "security overview", "what CVEs need fixing". This skill is READ-ONLY. To actually fix issues, use the native-dependency-update skill.
autonomous-loops
by codewithmukesh
Autonomous iteration loops for .NET development: build-fix, test-fix, refactor, and scaffold loops. Each loop has bounded iterations, progress detection, and fail-safe guards that prevent infinite retries and wasted tokens. Load this skill when Claude needs to fix build errors, fix failing tests, perform multi-step refactoring, scaffold a new feature, or when the user says "fix the build", "make the tests pass", "refactor this", "scaffold", "generate and verify", "keep going until it works", "autonomous", or "loop".
options-payoff
by himself65
Generate an interactive options payoff curve chart with dynamic parameter controls. Use this skill whenever the user shares an options position screenshot, describes an options strategy, or asks to visualize how an options trade makes or loses money. Triggers include: any mention of butterfly, spread (vertical/calendar/diagonal/ratio), straddle, strangle, condor, covered call, protective put, iron condor, or any multi-leg options structure. Also triggers when a user pastes strike prices, premiums, expiry dates, or says things like "show me the payoff", "draw the P&L curve", "what does this trade look like", or uploads a screenshot from a broker (IBKR, TastyTrade, Robinhood, etc). Always use this skill even if the user only provides partial info — extract what you can and use defaults for the rest.
tracing-downstream-lineage
by astronomer
Trace downstream data lineage and impact analysis. Use when the user asks what depends on this data, what breaks if something changes, downstream dependencies, or needs to assess change risk before modifying a table or DAG.
