- 02-rl-rewardagentscope-ai/OpenJudgeBuild RL reward signals using the OpenJudge framework. Covers choosing between pointwise and pairwise reward strategies based on RL algorithm, task type, and cost; aggregating multi-dimensional pointwise scores into a scalar reward; pairwise tournament reward for GRPO on subjective tasks (net win rate across group rollouts); generating preference pairs for DPO/RLAIF; and normalizing scores for training stability. Use when building reward models, scoring rollouts for GRPO/REINFORCE, generating preference data for DPO, or doing Best-of-N selection.ProductivityNo warnings★ 1K↓ —
- isca-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when planning a full ISCA campaign on a calendar — working back from the expected mid-November abstract and paper deadlines to freeze simulation evidence in time, staffing the winter two-round review wait, preparing for the February-March rebuttal and revision window, and branching to camera-ready, artifacts, and the June conference.ProductivityNo warnings★ 1.4K↓ —

- plan-campaign-budget-and-testsgooseworks-ai/goose-skillsStep of the plan-campaign playbook: splits the budget across chosen channels, checks per-channel minimums, and writes the test plan and paid structure. Run plan-campaign instead; not for direct use.TestingNo warnings★ 1.3K↓ —
- debugging-livekit-agentsfcakyon/claude-codex-settingsDrives a live multi-turn conversation with a LiveKit agent running locally, using `lk agent debugger`.

- meta-evalagentscope-ai/OpenJudgeUse when the user wants to build an evaluation system for an LLM/agent application but doesn't know where to start — they have traces, prompts, RAG pipelines, or nothing at all. Also use when the user mentions evaluation, eval, benchmarking, testing LLM quality, measuring agent performance, assessing RAG accuracy, or wants to compare prompts/models. This skill is the entry router: it asks diagnostic questions then recommends which sub-skill (local workflow) to use next.TestingNo warnings★ 1K↓ —
- localization-strategykostja94/marketing-skillsPlan, audit, implement, migrate, or validate localization for multilingual products and websites, including locale scope, market readiness, URL architecture, content coverage, hreflang coordination, rollout, and production verification.

Use write-tests to implement the resulting test changes.TestingNo warnings★ 1.4K↓ —
- pmf-strategykostja94/marketing-skillsWhen the user wants to validate product-market fit, measure PMF, or plan before scaling. Also use when the user mentions "PMF," "product-market fit," "product market fit," "Sean Ellis test," "very disappointed," "vitamin vs painkiller," "PMF validation," "premature scaling," or "validate before scale."

test-error-states
reticlehq/reticle
From the author
Force the states a happy-path run never reaches (a failing API, an empty list, a slow request, a timeout, an expired session, a toast that auto-dismisses) and check the UI actually handles them. Use when error handling was written but never run, when a loading or empty state needs verifying, when a bug only happens on a slow connection, or when a timer, poll, debounce or retry needs testing without sleeping.
