- test-error-statesreticlehq/reticleForce 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.TestingNo warnings★ 1.2K↓ —
- research-audience-score-segment-qagooseworks-ai/goose-skillsStep of the research-audience playbook: scores and tiers list rows, groups them into segments with an angle each, runs the pre-handover checks and writes the list files. Run research-audience instead; not for direct use.TestingNo warnings★ 1.3K↓ —
- openship-deployfcakyon/claude-codex-settingsThis skill should be used when the user asks to "deploy with OpenShip", "manage a self-hosted OpenShip instance", "debug an OpenShip deployment", or manage its domains, storage, backups, or upgrades through the CLI.DevOpsNo warnings★ 1.2K↓ —

- research-audience-signals-and-hooksgooseworks-ai/goose-skillsFor a list of companies, finds dated, linked timing signals from the last 90 days (funding, new leaders, hiring, launches), drops stale ones and noise, scores timing, and gives one personal hook per person from their recent public work. Facts only, no message copy. Use alone when you already have the company list and, for hooks, the people; otherwise run research-audience.ScienceNo warnings★ 1.3K↓ —

- documenthashgraph-online/awesome-codex-pluginsRecord a decision, document existing code, or file a supplied research material. Modes: document decision (ADR, RFC, or rule), document code (spec, doc, guide, or scenario for existing behavior), document research (only when a finished report or one external material is already in hand). Use for 'we decided', 'record this decision', 'document why we chose X', 'make it our standard', 'draft an RFC', 'should we switch to Y' proposals, 'resolve the RFC', 'we accepted the proposal', 'document the auth module', 'capture how the payment system works', reference material, how-to instructions, or a user flow with examples over an existing spec. Name the type inside the subject to skip the type question. Planning a feature or an intended user journey → /archcore:plan.

00-arena-router
agentscope-ai/OpenJudge
From the author
Use when the user wants to compare or benchmark multiple LLMs/agents arena-style but it's unclear which specific workflow fits — a general-purpose win-rate comparison on a custom task, or a benchmark specifically about reference/citation hallucination rate. Also use when the user mentions model arena, agent arena, pairwise model comparison, win-rate ranking, or comparing models on a task and hasn't specified whether that task is generic or about citation accuracy. This skill is the entry router for the arena-eval suite: it asks one diagnostic question when needed, then recommends the workflow or workflows needed to cover the request.
