dingxingdi Skill: programmatic-macro-skill-composition
1. Capability Definition & Real Case
- Professional Definition: The ability to induce and apply programmatic macro-actions from successful trajectories to handle long-horizon agentic tasks more efficiently. This involves identifying repetitive or procedurally linked primitive actions (such as navigation, form-filling, and selection) and abstracting them into verifiable, composable Python-like functions that the planner can invoke as single units within a complex action program. By replacing long sequences of low-level steps with these high-level macro-calls, the agent reduces the planning horizon, minimizes potential cumulative errors, and ensures functional consistency across environments.

Real Case
[Case 1]
- Initial Environment: A web agent is on the homepage of an e-commerce platform. It has access to primitive tools like 'click', 'fill', and 'scroll', and its goal is to manage address data for a user who has just relocated.
- Real Question: I recently moved. Can you change my billing address to '231 Willow Way, Suite 100, Chicago, IL, 60601'? Then, update my shipping address to: 987 Sycamore Circle, Philadelphia, PA, 19102.
- Real Trajectory: 1. {action: navigate_to_address_settings('billing'), observation: 'Address form visible'}; 2. {action: update_address_details('231 Willow Way', 'Suite 100', 'Chicago', 'IL', '60601'), observation: 'Billing address updated'}; 3. {action: navigate_to_address_settings('shipping'), observation: 'Address form visible'}; 4. {action: update_address_details('987 Sycamore Circle', '', 'Philadelphia', 'PA', '19102'), observation: 'Shipping address updated'}; 5. {action: send_msg_to_user('Both addresses updated successfully')}
- Real Answer: The agent successfully updates both billing and shipping records by invoking higher-level 'address update' macros that wrap approximately 12-15 primitive click and fill actions into distinct, verifiable blocks.
- Why this demonstrates the capability: This demonstrates programmatic macro composition because the agent uses high-level functions (navigate_to_settings, update_details) to solve a complex 25+ step sequence in only 5 macro-steps. It proves the agent can manage long-horizon constraints without roaming into redundant exploration, specifically by using a 'verified' routine that ensures the parameters (address strings) are correctly injected into a repeatable workflow.
[Case 2]
- Initial Environment: The agent is at a blank search page for an online catalog. It needs to find and organize multiple heterogeneous items for a shopping list.
- Real Question: Add a wireless headphone, a water bottle, a notebook, a ground coffee, and a mug to my shopping cart.
- Real Trajectory: 1. {action: search_and_add_to_cart('wireless headphone'), observation: 'Headphone in cart'}; 2. {action: search_and_add_to_cart('water bottle'), observation: 'Bottle in cart'}; 3. {action: search_and_add_to_cart('notebook'), observation: 'Notebook in cart'}; 4. {action: search_and_add_to_cart('ground coffee'), observation: 'Coffee in cart'}; 5. {action: search_and_add_to_cart('mug'), observation: 'Mug in cart'}
- Real Answer: All five items are correctly identified and added to the cart using a single repeatable programmatic skill that abstracts the entire search-and-select process.
- Why this demonstrates the capability: This demonstrates the efficacy of ASI in scaled-up web activities. Instead of regenerating the same 4-step primitive sequence (click box, type name, enter, click add) five times—which increases the chance of a hallucinated element or ID—the agent uses a single composable skill
search_and_add_to_cart. This drastically improves the 'steps-to-success' ratio and simplifies the planning task to a simple iteration over the list of item names.
Pipeline Execution Instructions
To synthesize data for this capability, you must strictly follow a 3-phase pipeline. Do not hallucinate steps. Read the corresponding reference file for each phase sequentially:
Phase 1: Environment Exploration Read the exploration guidelines to discover raw knowledge seeds:

references/SELECTION.mdPhase 3: Data Synthesis Once a trajectory passes Phase 2, read the synthesis instructions to generate the final data:
