- clari-hello-worldjeremylongshore/tons-of-skills-marketplaceRun one bounded Clari forecast export through request, status polling, and result retrieval. Use when proving Revenue API connectivity or learning the job lifecycle. Trigger with: "run my first Clari export", "test Clari connectivity", "export a forecast snapshot".TestingNo warnings★ 2.9K↓ —
- codejeremylongshore/tons-of-skills-marketplaceUse BEFORE generating, refactoring, reviewing, or debugging code. Trigger phrases include "write a function/script/class for X", "review this code/diff/PR", "refactor this", "debug this error", "is this implementation correct", "what's wrong with this code", "improve this code", "translate from X to Y", or any prompt with a code block the user wants you to act on. Also fires when planning architectural changes, picking algorithms or data structures, or evaluating dependency upgrades. Calls the code MCP tool to retrieve an engineering scaffold (failure pattern, procedure, correct-pattern example, verification step) before generating. Catches hallucinated APIs, lost edge cases, premature algorithm commitment, silent contract violations, refactors that change behavior masked by passing tests. Do NOT trigger for pure code reading with no action requested, simple syntax questions, file system operations, running existing tests, or confirming an existing pattern is fine.EngineeringNo warnings★ 2.9K↓ —
- nemo-fabric-build-adapterNVIDIA/skillsBuild, migrate, review, and maintain third-party NVIDIA NeMo Fabric adapters against the public adapter contract. Use when creating adapter or target descriptors, mapping AgentConfig into an agent harness or custom-agent runtime, implementing start/invoke/stop, declaring schemas and capabilities, packaging discovery metadata, or assessing adapter conformance. Do not use for consumer applications that only call the NVIDIA NeMo Fabric SDK.LegalNo warnings★ 3.8K↓ —

- skill-improvertrailofbits/skillsRuns an autonomous review-and-fix improvement loop over a Claude Code skill until a review comes back clean, with a cross-round findings ledger, escalation when fixes stop converging, and a mechanical scope guard. Reviews are performed by the plugin-dev skill-reviewer agent. Use to fix skill quality issues, iteratively refine a skill, or resume a loop after an escalation ('fix my skill', 'improve this skill until it passes review', 'skill improvement loop'). NOT for a one-time review — use the plugin-dev skill-reviewer agent directly.EngineeringNo warnings★ 7.9K↓ —

- validate-skillmdjeremylongshore/tons-of-skills-marketplaceValidate and grade SKILL.md files with the marketplace rubric, static production checks, and optional J-Rig behavioral evidence. Use when creating a skill, checking quality, preparing a marketplace submission, or reviewing evaluation results. Trigger with "validate this skill", "grade my skill", "deep eval", "check SKILL.md", or "/validate-skillmd".OtherNo warnings★ 2.9K↓ —
