dingxingdi Skill: long-form-breadth-depth-coherence
1. Capability Definition & Real Case
- Professional Definition: The capability to generate long-form written documents that satisfy large output requirements while preserving global relevance, topic breadth, topic depth, local clarity, and cross-section coherence over extended length.
- Dimension Hierarchy: Grounded Expository Writing->Long-form Expansion->long-form-breadth-depth-coherence
Real Case
[Case 1]
- Initial Environment: The agent receives a blank long-form writing environment and a single historical request whose target length far exceeds ordinary one-pass responses.
- Real Question: Write a 10,000-word article on the history of the Roman Empire.
- Real Trajectory: The agent decomposes the task into a writing plan, assigns paragraph-level or section-level subtasks, writes serially with previous sections in context, and checks breadth, depth, and coherence while length accumulates.
- Real Answer: A long historical article that approaches the requested size and remains organized across introduction, rise, institutions, expansion, crisis, decline, and legacy.
- Why this demonstrates the capability: Reaching 10,000 words is not enough by itself. The article must also remain coherent, relevant, and non-repetitive across many sections. This case therefore probes the combined management of output length and document-level writing quality.
[Case 2]
- Initial Environment: The agent receives a long-form instruction to produce an educational or analytical report that explicitly requires more than 4,000 words and expects section-level continuity.
- Real Question: Expand this short brief on urban heat mitigation into a full-length, 4,500-word public-facing report with clear sections and practical recommendations.
- Real Trajectory: The agent creates section budgets, serially writes each section while retaining the prior context, introduces transitions between technical explanation and policy guidance, and performs anti-repetition checks before concluding.
- Real Answer: A sectioned public-facing report that covers causes, measurement, health effects, infrastructure responses, policy tradeoffs, and implementation guidance.
- Why this demonstrates the capability: The challenge is to sustain both breadth and depth over a long output without letting sections drift apart or echo one another. The report must not only be long but also structurally balanced and readable. This makes it a direct test of document-scale writing control.
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/EXPLORATION.mdPhase 2: Trajectory Selection Once Phase 1 is complete, read the selection criteria to evaluate the trajectory:
references/SELECTION.mdPhase 3: Data Synthesis Once a trajectory passes Phase 2, read the synthesis instructions to generate the final data:
