- exa-ci-integrationjeremylongshore/tons-of-skills-marketplaceAdd deterministic Exa contract checks to CI while keeping live credentials, spend, and volatile web results out of ordinary pull requests. Use when operating or reviewing this Exa boundary. Trigger with "Exa ci integration", "review Exa ci integration", or "fix Exa ci integration".LegalNo warnings★ 2.9K↓ —

- tao-train-deformable-detrNVIDIA/skillsDeformable DETR for 2D object detection. Uses deformable attention for efficient multi-scale feature processing, lighter than DINO with competitive accuracy. Use when training, evaluating, exporting, quantizing, or running inference for a TAO Deformable-DETR model. Trigger phrases include "train deformable-detr", "Deformable DETR object detection", "lightweight DETR detector".OtherNo warnings★ 3.8K↓ —

- fondo-cost-tuningjeremylongshore/tons-of-skills-marketplaceOptimize Fondo costs by maximizing R&D tax credits, choosing the right plan, and reducing unnecessary bookkeeping complexity. Trigger: "fondo costs", "fondo pricing", "maximize R&D credit", "fondo ROI".FinanceNo warnings★ 2.9K↓ —
- stock-liquidityhimself65/finance-skillsAnalyze how liquid a stock is using Yahoo Finance data (yfinance): bid-ask spreads, volume and dollar volume (ADTV), top-of-book and options depth, square-root market impact and slippage estimates, turnover ratio, and Amihud illiquidity, rolled into a liquidity grade. Use this skill whenever the user asks about liquidity or trading costs — how easily a position can be entered or exited, what a large order would do to the price, spread or execution-cost estimates, order book depth, volume patterns, or liquidity comparisons — especially for small caps, penny stocks, and thinly traded names.FinanceNo warnings★ 3.5K↓ —
- yfinance-datahimself65/finance-skillsFetch financial and market data with the yfinance Python library (Yahoo Finance). Use this skill whenever the user wants stock data: current quotes and price history, financial statements (income statement, balance sheet, cash flow), options chains, dividends and splits, earnings and analyst estimates, price targets and ratings, institutional and insider holdings, news, multi-ticker comparisons, stock screens, or sector and industry data. Use it even when the user gives only a ticker symbol (AAPL, MSFT, TSLA) and the intent has to be inferred. For earnings previews or recaps, estimate revisions, valuation, correlation, liquidity, or ETF premium analysis, prefer the dedicated skill.FinanceNo warnings★ 3.5K↓ —
- saas-valuation-compressionhimself65/finance-skillsAnalyze how a private SaaS company's ARR valuation multiple changed across funding rounds, and attribute the compression or expansion to rate cycles and macro selloffs, growth deceleration, narrative shifts (including an AI premium), competition, and investor demand, benchmarked against private-market medians and peers. Use this skill whenever the user asks about valuation compression, ARR multiples, round-to-round valuation or multiple changes, down rounds, or wants to compare a VC-backed software company's funding rounds. Research the rounds rather than answering from memory.FinanceNo warnings★ 3.5K↓ —
- whybacknotprop/pstackUse for 'why does X work this way', 'why we picked Y', design rationale, regressions, postmortems, or data-backed thresholds. Discovers available MCPs and queries each evidence category (source control, issue tracker, long-form docs, real-time chat, infrastructure observability, error tracking, product analytics warehouse) in parallel, then returns a cited read on decisions and tradeoffs. Use how for runtime behavior.DevOpsNo warnings★ 3.3K↓ —
- exploitsdavepoon/buildwithclaudeAnalyze exploit intelligence for a vulnerability against the current repositorySecurityNo warnings★ 3.7K↓ —
- fxmacrodatadavepoon/buildwithclaudeLook up official macroeconomic releases, central-bank policy rates, release calendars and FX rates for 22 currencies through the FXMacroData MCP server. Use for questions about CPI, GDP, jobs data, rate decisions, bond yields or what data is due next, when the answer should come from the published number rather than news coverage. Remote server at https://mcp.fxmacrodata.com/mcp; USD works without a key.OtherNo warnings★ 3.7K↓ —
- yt-outlinejeremylongshore/tons-of-skills-marketplaceCreate a filmable YouTube outline and demo prep checklist from approved brief and packaging artifacts. Use when planning screen actions, section timing and rehearsals. Trigger with "outline this video" or "demo prep checklist".MediaNo warnings★ 2.9K↓ —
- provider-framework-migrationhashicorp/agent-skillsMigrate Terraform provider resources and data sources from Plugin SDKv2 to the Plugin Framework: muxing both plugins in one provider (terraform-plugin-mux, tf5to6server), per-resource migration workflow, SDKv2-to-Framework schema mapping (ForceNew, ValidateFunc, DiffSuppressFunc, Default, Timeouts, blocks), null-vs-zero-value behavioral traps, and state-compatibility verification. Use when converting or translating SDKv2 resources to the Framework, setting up a muxed provider server, deciding whether a resource should be migrated at all, or debugging plan diffs and state errors that appeared after a migration.OfficialDevOpsNo warnings★ 910↓ —
- provider-actionshashicorp/agent-skillsImplement Terraform Provider actions using the Plugin Framework. Use when developing imperative operations that execute at lifecycle events (before/after create, update, destroy).OfficialDevOpsNo warnings★ 910↓ —
- gsd:new-milestonedavepoon/buildwithclaudeStart a new milestone cycle — update PROJECT.md and route to requirementsPlanningNo warnings★ 3.7K↓ —
- variant-analysistrailofbits/skillsHunts for the other instances of a bug already found — the variants of one root cause across a codebase. Use immediately after a vulnerability, logic bug, or bad pattern turns up in a specific file and the question becomes where else it occurs, including the bare conversational form ("are there others like this?", "is this the same bug?"). Also for generalizing one known instance into a CodeQL or Semgrep query for its whole pattern family, and for triaging a set of look-alike candidates against a known root cause. Not for initial discovery with no bug in hand.SecurityNo warnings★ 7.9K↓ —
- exa-known-pitfallsjeremylongshore/tons-of-skills-marketplaceAudit an Exa integration for stale search types, unsafe secrets, ignored partial failures, unbounded content work, weak citations, and orphaned asynchronous resources.

- apify-install-authjeremylongshore/tons-of-skills-marketplaceInstall and configure Apify SDK, CLI, and API client authentication.
