Once a theme is chosen, it can be applied to any artifact.013Theming Systemowl-listener/designer-skillsDesign theming architecture — brand variants, dark mode, and high-contrast — mapped through token layers. Use when one system must serve multiple themes. For a single palette use `color-system` (ui-design); for dark mode craft use `dark-mode-design` (ui-design).01Thermo Nuclear Reviewcursor/pluginsComprehensive security and correctness audit of a branch's changes. Use for thermo nuclear, thermonuclear, or deep review requests, or branch/PR diff audits focused on bugs, breaking changes, security issues, devex regressions, and feature-gate leaks.01Thermoscursor/pluginsLaunch both thermo-nuclear review subagents in parallel, then synthesize their findings. Use for thermos, double thermo review, or combined bug/security and code-quality branch audits.01Thesis Trackeranthropics/financial-servicesMaintain and update investment theses for portfolio positions and watchlist names. Track key data points, catalysts, and thesis milestones over time. Use when updating a thesis with new information, reviewing position rationale, or checking if a thesis is still intact. Triggers on "update thesis for [company]", "is my thesis still intact", "thesis check", "add data point to [company]", or "review my positions".01Thick Clientzhaoxuya520/reverse-skillUse for authorized security testing of desktop thick clients including local storage, update channels, IPC, traffic, and client-side trust boundaries.02Things Macopenclaw/openclawAdd, update, list, search, or inspect Things 3 todos, inbox, today, projects, areas, and tags on macOS.01Thinktw93/wazaTurns rough ideas into approved, decision-complete plans before coding. Use when planning architecture, judging whether to build, or writing a handoff. Not for bug fixes or small edits.04Thinking Bounded Rationalitytjboudreaux/cc-thinking-skillsUse when search or investigation could run forever. Set an explicit good-enough threshold first, then stop at the first option that clears it.01Thinking Circle Of Competencetjboudreaux/cc-thinking-skillsUse when a specific claim may lack grounding. Check evidence boundary, size wrongness cost, then answer, fetch, or abstain — never confabulate.01Thinking Cynefintjboudreaux/cc-thinking-skillsWhen the right response mode is unclear, classify the cause-effect domain first; decompose disorder.01Thinking Effectuationtjboudreaux/cc-thinking-skillsUnder genuine uncertainty with no reliable forecast, inventory means, cap downside at affordable loss, act for commitments, and let goals emerge from controllable moves.01Thinking First Principlestjboudreaux/cc-thinking-skillsWhen a constraint is treated as fixed, separate physics from convention, keep only independently supported primitives, and rebuild the simplest solution that satisfies real constraints.01Thinking Five Whys Plustjboudreaux/cc-thinking-skillsWhen a fault is localized and the proximate cause is known but the systemic root is not, chain evidence-linked whys with a counterfactual stop and a countermeasure.01Thinking In Betspmprompt/claude-plugin-product-managementUse when asked to "thinking in bets", "make decisions under uncertainty", "think probabilistically", "avoid resulting", "separate decision quality from outcomes", or "reduce bias in decisions". Helps make explicit bets and evaluate decisions on process, not results. The Thinking in Bets framework (from Annie Duke) applies poker strategy to business and life decisions.01Thinking Jobs To Be Donetjboudreaux/cc-thinking-skillsDeciding what to build or why adoption fails. Recover the progress users hire a solution for under a circumstance, then rank by outcome and competing workarounds.01Thinking Kepner Tregoetjboudreaux/cc-thinking-skillsUse when a selective defect needs IS/IS-NOT difference analysis or a consequential option choice needs must/want weighting and adverse-consequence comparison.01Thinking Lindy Effecttjboudreaux/cc-thinking-skillsUse when longevity of a non-perishable option matters. Treat survival duration as a remaining-life prior, then check domain drift before favoring the proven.01Thinking Map Territorytjboudreaux/cc-thinking-skillsWhen a claim, doc, test, metric, or assumption conflicts with observed behavior, stop theorizing from the map and verify the live code or data; let territory overrule.01Thinking Margin Of Safetytjboudreaux/cc-thinking-skillsWhen provisioning, setting a limit, or committing an estimate under uncertainty, size a buffer to residual error and the cost of breach—not to the optimistic edge.01Thinking Model Combinationtjboudreaux/cc-thinking-skillsWhen one mental model leaves a material blind spot on a multi-domain or high-stakes problem, sequence complementary models with named roles and a conflict rule.01Thinking Model Routertjboudreaux/cc-thinking-skillsWhen unsure which thinking skill fits, map domain and problem type, then return NONE or one primary skill by default (at most three complementary).01Thinking Oodatjboudreaux/cc-thinking-skillsUse under time pressure when the situation is still changing and you must act before certainty — cycle Observe→Orient→Decide→Act on ~70% confidence, then re-observe.01Thinking Opportunity Costtjboudreaux/cc-thinking-skillsBefore committing scarce time, people, or money, name the best forgone use of those resources and the value delta of the chosen path versus that alternative.01Thinking Orbsmengto/skillsAdd accessible animated AI loading and agent-status indicators with the React thinking-orbs library. Use when a chat, copilot, voice, search, generation, or tool-running interface needs a semantic working, searching, solving, listening, composing, or shaping state; when replacing a generic spinner with an AI activity orb; or when implementing the library's size, theme, speed, pause, reduced-motion, and canvas behavior.03Thinking Partnermattnowdev/thinking-partner>03Thinking Pre Mortemtjboudreaux/cc-thinking-skillsBefore committing to a plan or launch, assume it already failed and reason backward through concrete causes — convert failure paths into mitigations, gates, and stop checks.01Thinking Probabilistictjboudreaux/cc-thinking-skillsUse when forecasting, estimating, or sizing risk — anchor on base rates, give ranges, update prior→likelihood→posterior on evidence, and factor unmeasured quantities into order-of-magnitude bounds.01Thinking Red Teamtjboudreaux/cc-thinking-skillsFor authorized security review of code, auth, or APIs you control, model the attacker, map the attack surface, and report only findings with a reproducible exploit path and verified mitigation.01Thinking Reversibilitytjboudreaux/cc-thinking-skillsBefore heavy deliberation, classify the decision as cheap or costly to undo; decide two-way doors fast and stage one-way doors to preserve options.01Thinking Scientific Methodtjboudreaux/cc-thinking-skillsWhen a symptom has several plausible causes, rank falsifiable hypotheses and run the cheapest discriminating observation first; prefer least-assumptive survivors only after evidence fit.01Thinking Second Ordertjboudreaux/cc-thinking-skillsWhen a change has effects past the immediate fix—incentives, scale, feedback—trace consequence chains with timing and probability before committing.01Thinking Socratictjboudreaux/cc-thinking-skillsWhen a request is vague, assumption-laden, or "obvious," ask the few load-bearing questions that expose hidden requirements before building or committing.01Thinking Steel Manningtjboudreaux/cc-thinking-skillsBefore rejecting a proposal or reflexively agreeing, build the strongest faithful opposing case, state agreement conditions, then update or reaffirm.01Thinking Systemstjboudreaux/cc-thinking-skillsWhen behavior is emergent across components—fixes elsewhere break, loops/delays dominate—map boundary, stocks/flows, feedback, archetypes, then rank leverage.01Thinking Theory Of Constraintstjboudreaux/cc-thinking-skillsWhen throughput or latency is pipeline-limited, identify the single binding constraint and exploit, subordinate, elevate, then recheck—ignore non-constraints.01Thinking Thought Experimenttjboudreaux/cc-thinking-skillsWhen a real test is too rare, large, or irreversible, run a controlled counterfactual: isolate one variable, fix conditions, trace the mechanistic chain, and bound what the result implies.01Thinking Triztjboudreaux/cc-thinking-skillsWhen two design requirements seem mutually exclusive, name the contradiction, separate conflicting states, then invent a concrete no-compromise resolution.01Thinking Via Negativatjboudreaux/cc-thinking-skillsUse when the reflex is to add a feature, layer, or process. Prefer removing harmful or nonessential elements first, with an irreversibility guard before deletion.01Third Partypatternsdev/skillsTeaches strategies for mitigating third-party script performance impact. Use when third-party scripts like analytics, ads, or widgets are degrading your page load times or Core Web Vitals.01Third Party Integrationaj-geddes/useful-ai-prompts>08Thought Based Reasoningneolabhq/context-engineering-kitUse when tackling complex reasoning tasks requiring step-by-step logic, multi-step arithmetic, commonsense reasoning, symbolic manipulation, or problems where simple prompting fails - provides comprehensive guide to Chain-of-Thought and related prompting techniques (Zero-shot CoT, Self-Consistency, Tree of Thoughts, Least-to-Most, ReAct, PAL, Reflexion) with templates, decision matrices, and research-backed patterns01Thread Abort Migrationdotnet/skills>01Thread Listassistant-ui/skillsBuilds and customizes multiple conversation lists in assistant-ui with the runtime connected ThreadList and ThreadListSidebar elements, ThreadListPrimitive, ThreadListItemPrimitive, ThreadListItemMorePrimitive, useAui, useAuiState, and threads.selectionChanged. Use when adding a conversation sidebar, switching, archiving, renaming, deleting, searching, grouping, paginating, or persisting threads, or when thread state is stale after authentication. Covers AssistantCloud, RemoteThreadListRuntime, and ExternalStoreThreadListAdapter. Use runtime for the active conversation runtime, cloud for managed authentication and persistence, and elements for registry installation and styling.04
