-
cercova-studios Skill Dispatching Parallel AgentsUse when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies
-
zjunlp Bundle Alfworld Locate Target ObjectNavigates to a suspected location and identifies a target object. Use when your goal requires finding a specific object (e.g., "potato", "plate") and its location is not immediately known. Moves to a relevant receptacle (like a fridge or cabinet), checks its contents, and outputs the object's location or confirms its absence.
-
zjunlp Bundle Scienceworld Liquid PourerTransfers the contents of a source liquid container into a target container for mixing or preparation. Use this skill when you need to combine multiple substances (such as paints or chemicals) into a single vessel, or when a liquid must be moved from one container to another before processing.
-
zjunlp Bundle Scienceworld Room ExplorerPerforms an initial survey of a room to identify all visible objects, containers, devices, and their states using the 'look around' action. Use this skill when you first enter a new location, need to refresh your understanding of the environment, or must identify available resources before planning a sequence of actions. Returns a detailed observation that serves as foundational context for subsequent tasks.
-
zjunlp Bundle Alfworld Object State InspectorInspects a receptacle's contents by navigating to it and reading the observation. Use when you need to check what is on or inside a receptacle (e.g., "what's on the shelf", "is the holder empty", "check the table for items"). Executes `go to {receptacle}`, parses the observation listing items present, and decides whether to take an item, search elsewhere, or proceed.
-
zjunlp Bundle Scienceworld Object LocatorSearches for a specific target object across multiple rooms by systematically teleporting to likely locations and examining each room. Use this skill when you need to find an object whose exact location is unknown. Iterates through candidate rooms using teleport and look around, checks for the object, and continues until found, returning the object's location.
-
coowoolf Skill Pre Mortem Kill CriteriaUse before launching products or signing contracts, when needing to combat sunk cost fallacy, or when standard pre-mortems fail to change behavior
-
coowoolf Skill Entropy Defense MechanismDeliberately impose artificial constraints and simplification rules to counteract organizational drift toward complexity. Complexity kills companies—fight it with binary rules.
-
coowoolf Skill Pr Faq Product ValidationWrite a future-dated Press Release and FAQ before any coding begins to ensure the product solves a real customer problem. Work backwards from the customer, not forward from capabilities. Amazon's foundational process.
-
coowoolf Skill Fear And Anger Decision FilterFear creates exaggerated negative predictions. When gripped by fear, bet that the opposite will happen if you act against it, then take action. Use for high-stakes decisions that feel emotionally dangerous.
-
coowoolf Skill Divergent Working BackwardsUse when defining new product lines or major pivots, when single PR/FAQ leads to tunnel vision, or when giving leadership real strategic choices instead of yes/no decisions
-
coowoolf Skill Delicate Conversation ScriptsUse when delivering difficult feedback (performance issues, firing, promotion denial), when managers avoid necessary conversations due to fear, or when needing structured scripts for high-stakes communication
-
coowoolf Skill House Operational ArchitectureA three-part structural framework for building a scalable company—Foundation (Founding Documents), Posts & Beams (Supporting Structures), and Mechanicals (Operating Cadence). Use when moving from PMF to scaling the org.
-
coowoolf Skill Dimensionality Of Self ManagementView yourself as an entity with infinite dimensions rather than a single good/bad identity. Strengths and weaknesses are often the same trait in different contexts. Use during performance reviews or when receiving tough feedback.
-
anntnzrb Bundle Mk ChangelogGenerate Keep a Changelog entries and release notes from Git commits, PRs, or staged diffs.
-
anntnzrb Bundle Vox InterpresUse when audio needs tempo, key, section, energy, metadata, codec, or segment analysis.
-
anntnzrb Bundle Git WorktreesUse when Git worktrees must be created, consumed, removed, leased, or routed through a worktree manager.
-
anntnzrb Bundle Market HunterSearch, compare, verify, and score AI subscriptions, licenses, and digital accounts across deal marketplaces.
-
zjunlp Bundle Webshop Product Detail InspectorThis skill examines a product detail page to verify specific attributes or select options like size, color, or quantity. It is used after clicking on a product, to confirm that the item matches the user's needs (e.g., checking for '10 slots' option, price, material). The input is the product page observation, and the output is an action to select a required variant (e.g., click[10 slots]) or proceed if criteria are satisfied.
-
zjunlp Bundle Webshop Product Detail NavigatorNavigates to and interacts with a specific product's detail page. This skill is triggered after a candidate product ID is selected from search results. It performs the click action to load the product page and then identifies available interactive elements (like flavor or size selectors) that need to be configured to match the user's requirements.
-
zjunlp Bundle Alfworld Search Pattern ExecutorSystematically searches a sequence of likely locations for a target object based on common sense. Use when you need to find a specific object and know which receptacles to check but not which one contains it. Takes a list of candidate receptacles, orchestrates navigation and inspection, and outputs when the target is found or all locations are exhausted.
-
zjunlp Bundle Scienceworld Process MonitorThis skill observes the state of an active apparatus and its contents to track progress. Use when you need to periodically check for state changes (e.g., solid to liquid) during a heating or reaction process. The skill uses 'look at' or 'examine' actions on the apparatus and substance.
-
zjunlp Bundle Scienceworld Device ActivatorActivates a device (e.g., blast furnace, stove) to initiate a process like heating. Use this skill when you have placed materials inside a device and need to start its operation. Takes a device name as input and outputs a confirmation of activation, enabling tasks that require energy input or material processing to progress.
-
lerianstudio Bundle Ring Writing PlansWriting a rolling-wave phased implementation plan from a spec before coding: a phase-epic-task hierarchy where Phase 1 is detailed into dispatch-ready tasks and later phases stay epic-level for elaboration during execution. Use when a multi-file feature needs decomposition; runs after ring:exploring-codebases or pre-dev gates, hands off to ring:executing-plans or ring:running-dev-cycle. Skip for single-file changes or spikes.
