This document covers the complete lifecycle: knowledge acquisition, skill extraction, fragmentation management, knowledge consolidation, and progress measurement. ## Theoretical Foundation This framework is grounded in **Nurture-First Development (NFD)** (Zhang, 2026, arXiv:2603.10808), which proposes that domain-expert agents should be grown through structured conversational interaction rather than pre-programmed. The core mechanism is the **Knowledge Crystallization Cycle**: fragmented knowledge embedded in operational dialogue is periodically consolidated into structured, reusable assets. Key insight from our experience: An agent went from needing 2 weeks to achieve top 10% in a Kaggle competition (S6E2, February) to achieving the same in 24 hours (S6E4, April) -- a 14x speedup attributable entirely to accumulated and crystallized knowledge. --- ## Part 1: The Learning Pipeline ### 1.1 Five-Stage Learning Loop ``` ┌──────────────────────────────────────────────────────────┐ │ │ │ ┌─────────┐ ┌──────────┐ ┌──────────┐ │ │ │ 1.

rarely refactor **L2 (Domain):** - These are "playbook" level skills for specific domains - They start as individual bug-fix or technique skills (fragmented) - Over time, related skills should be **merged** into comprehensive domain skills - Rule of thumb: If >5 skills share the same prefix, consider consolidation **L3 (Memory):** - These are "scratchpad" notes from current work - They should be **periodically crystallized** into L1 or L2 skills - If a memory file hasn't been referenced in 2+ weeks, archive it - Never let memory files accumulate without crystallization --- ## Part 3: Managing Skill Fragmentation ### 3.1 The Fragmentation Problem As an agent learns, it naturally accumulates many small, specific skills: - Bug fixes (e.g., `sklearn-target-encoder-multiclass-shape`) - Workarounds (e.g., `python-output-buffering`) - Domain snippets (e.g., `kaggle-auc-binary-submission-bug`) This creates **semantic noise**: when a problem arises, the skill matching system may surface multiple similar but slightly different skills, causing confusion. ### 3.2 When to Keep Skills Separate vs. Merge **Keep separate when:** - Different trigger conditions (different error messages, different contexts) - Skills are from different domains (ML bug vs. infrastructure issue) - The skill is the canonical reference for a specific problem **Merge when:** - Same domain prefix (e.g., 13 Re-ID skills → 2 comprehensive skills) - Trigger conditions overlap significantly - No skill has been auto-triggered in 30+ days (low specificity) - Skills share >50% of their solution content ### 3.3 Consolidation Strategy ``` Phase 1: Audit (Weekly) - Count skills by prefix/category - Identify clusters with >5 skills - Flag skills not triggered in 30 days Phase 2: Merge (Per cluster) - Group related skills - Identify the "primary" skill (most comprehensive or most triggered) - Absorb secondary skills' trigger conditions and solutions - Add "See also" references for edge cases - Delete merged skills Phase 3: Validate - Verify merged skill covers all original trigger conditions - Test that description enables semantic matching - Update SKILL_INDEX if maintained ``` ### 3.4 Example Consolidation: Kaggle Skills **Before (15 fragmented skills):** ``` kaggle-auc-binary-submission-bug kaggle-data-format-first kaggle-dataset-large-file-upload kaggle-feature-boundary kaggle-mlflow-tracking kaggle-optimal-blending kaggle-playground-external-data-validation kaggle-quantized-model-limitations kaggle-reid-csv-label-loading kaggle-reid-submission-workflow kaggle-submission-id-reset-index-bug kaggle-top-performer-replication kaggle-top-solution-replication kaggle-competition-best-practices (already comprehensive) kaggle (submission limiter) ``` **After (3-4 consolidated skills):** ``` kaggle-competition-best-practices (expanded: includes data-format, external-data, feature-boundary) kaggle-submission-toolkit (merged: auc-bug, reset-index-bug, large-upload, reid-workflow) kaggle-ensemble-strategies (merged: optimal-blending, top-performer-replication, top-solution-replication) kaggle (submission limiter - keep as-is) ``` --- ## Part 4: Notebook Integration Patterns ### 4.1 Why Notebooks Matter Google Colab / Jupyter notebooks serve a unique role in the agent training pipeline: - They are **executable documentation** -- theory becomes runnable code - They provide **isolated experimentation** -- try without breaking production - They enable **cross-platform verification** -- test on GPU/TPU environments ### 4.2 Integration Workflow ``` 1. Agent reads ML book chapter → creates memory file with key concepts 2. User shares notebook implementing those concepts → agent verifies understanding 3. Agent identifies patterns/gotchas not in the book → extracts as skills 4. Patterns crystallize into L1/L2 skills → available for future tasks ``` ### 4.3 Notebook-to-Skill Extraction Template When processing a notebook, extract knowledge in this structure: ```markdown ## From Notebook: [notebook name] ### Key Technique Learned [What new capability does this notebook teach?] ### Non-Obvious Insights [What did the notebook reveal that isn't obvious from documentation?] ### Gotchas Discovered [What errors or issues arose during execution?] ### Reusable Patterns [What code patterns can be extracted for future use?] ### Integration with Existing Skills [How does this relate to what the agent already knows?] ``` ### 4.4 Notebook as Verification Layer Notebooks also serve as the **verification step** between theory and practice: ``` Theory (Book/Paper) → "This technique should work for X" ↓ Notebook → "Confirmed: technique works, but requires Y adjustment for this dataset" ↓ Skill → "Use technique X with adjustment Y when encountering scenario Z" ``` Without the notebook verification step, the agent might memorize theoretical knowledge without understanding practical constraints, leading to naive application. --- ## Part 5: Progress Measurement ### 5.1 Capability Matrix Track agent capability across dimensions (rate 1-5): ```markdown ## Capability Assessment Template | Dimension | Rating | Evidence | |--------------------|--------|---------------------------------------------| | Feature Engineering| 1-5 | Can create TE, pairwise, polynomial features| | Model Training | 1-5 | Can tune XGB/LGB/CB/HGB effectively | | Ensemble Methods | 1-5 | Can implement hill-climbing, stacking | | Debugging | 1-5 | Can diagnose training issues quickly | | Experiment Mgmt | 1-5 | Can track and compare experiments | | Domain Knowledge | 1-5 | Understands medical/tabular/Re-ID domains | | Infrastructure | 1-5 | Can handle WSL/GPU/remote environments | ``` Rating scale: - **1**: Needs step-by-step guidance - **2**: Can follow known patterns - **3**: Can adapt patterns to new situations - **4**: Can discover and validate new approaches - **5**: Can innovate beyond documented techniques ### 5.2 Knowledge Growth Metrics Track these metrics periodically: ```bash # Total skills (should grow, then plateau as consolidation begins) ls ~/.claude/skills/*/SKILL.md | wc -l # Skills by category (should shift from many small to fewer large) ls ~/.claude/skills/ | sed 's/-.*//' | sort | uniq -c | sort -rn # Memory files (should cycle: create → crystallize → archive) ls ~/.claude/memory/ | wc -l # Stale memory files (not updated in 2+ weeks) find ~/.claude/memory/ -name "*.md" -mtime +14 | wc -l # Competition performance trend # Track CV and LB scores across competitions/versions ``` ### 5.3 Efficiency Indicators | Indicator | What It Measures | Target | |-----------|-----------------|--------| | Time to top 10% | Overall agent capability | Decreasing over competitions | | Skills triggered per task | Knowledge activation rate | High (most relevant skills surface) | | New skills per session | Learning rate | Steady (1-3 per session) | | Skills consolidated per month | Knowledge maturity | Increasing (signals crystallization) | | Repeated mistakes rate | Learning effectiveness | Decreasing toward zero | --- ## Part 6: Implementation Guide for Other Agents ### 6.1 Minimum Viable Setup To replicate this framework with any AI agent, you need: 1. **Skill extraction mechanism**: A skill that creates other skills (like Claudeception) 2. **Persistent memory**: Files or a database that survives session boundaries 3. **Semantic skill matching**: Ability to find relevant skills by description 4. **Three-layer structure**: Core / Domain / Contextual knowledge separation ### 6.2 Adaptation for Different Platforms | Platform | Skill System | Memory System | Notes | |----------|-------------|---------------|-------| | Claude Code | ~/.claude/skills/ | ~/.claude/memory/ | Native skill matching via description | | Codex CLI | ~/.codex/skills/ | ~/.codex/memory/ | Adapt skill format to Codex conventions | | Gemini CLI | Skills via GEMINI.md | Local files | May need different trigger mechanism | | Custom Agent | Any markdown files | Any persistent storage | Implement your own matching | ### 6.3 Critical Success Factors From our experience, these factors determined success: 1. **Extraction discipline**: Extract skills immediately after discovery, not later 2. **Quality over quantity**: A well-written comprehensive skill beats 5 fragmented ones 3. **Regular consolidation**: Schedule monthly skill audits and merges 4. **Memory hygiene**: Archive or delete stale memory files; don't let them accumulate 5. **External resources**: Books and notebooks are most valuable when they fill identified gaps 6. **Competitive feedback**: Kaggle LB scores provide objective measurement of capability growth --- ## Part 7: Case Study — 2 Months of Agent Development ### Timeline | Period | Competition | Time to Top 10% | Skills | Key Learning | |--------|-------------|-----------------|--------|-------------| | Feb 2026 | S6E2 (Medical) | ~2 weeks | ~10 | Basic ML pipeline, debugging patterns | | Mar 2026 | WorldQuant BRAIN | Ongoing | ~60 | Feature engineering, alpha expressions | | Apr 2026 | S6E4 (Irrigation) | ~24 hours | 156 | Reuse of crystallized knowledge | ### What Changed Between S6E2 and S6E4 **Eliminated time sinks:** - Research phase: 0 hours (vs 3+ days for S6E2) -- knowledge already in skills - Wrong directions: 0 (vs 5+ dead ends in S6E2) -- past mistakes documented as skills - Infrastructure issues: ~30 min (vs 2+ days for S6E2) -- WSL/GPU skills pre-built - Code template: ~1 hour (vs 3+ days for S6E2) -- previous scripts serve as templates **Knowledge reuse:** - 15 kaggle-* skills directly applied - 18 ML training skills directly applied - 6 infrastructure skills directly applied - `ml-expert` and `data-science-assistant` as foundation **This demonstrates the core principle**: Crystallized knowledge compounds over time. Each competition makes the agent faster at the next one, not just because it "remembers" but because knowledge is actively organized and retrievable. --- ## Part 8: Key Skills and Their Application Patterns This section documents the specific skills that power the nurture framework, including how they interact and when to use each one. Other agents can replicate these patterns on their own platforms. ### 8.1 Claudeception — The Knowledge Extraction Engine **What it does**: Automatically extracts reusable knowledge from work sessions and creates new skills. This is the "crystallization" mechanism that makes the entire framework work. **When it triggers**: - After fixing a non-obvious bug (solution required >10 min investigation) - After discovering a workaround for a tool/framework limitation - After trial-and-error success (tried multiple approaches before finding what works) - After finding a configuration insight specific to the project - When user explicitly asks "save this as a skill" or "what did we learn?" **How it works in practice**: ``` 1. Problem encountered during work 2. Solution found through investigation/experimentation 3. Claudeception evaluates: Is this knowledge reusable? Non-trivial? Specific? Verified? 4. If yes → Creates new skill with: - YAML frontmatter (name, description with trigger conditions, version, date) - Problem/Context section - Step-by-step Solution - Verification method - Notes and caveats 5. Skill saved to ~/.claude/skills//SKILL.md 6. Immediately available for future sessions ``` **Real examples from our experience**: - `python-output-buffering`: After wasting 45 min on "why is my log file empty?", extracted the knowledge that `nohup python` uses full buffering → always use `python3 -u` - `catboost-multicore-config`: After CatBoost took 8 hours for 5 folds on CPU, discovered `task_type='CPU'` with `thread_count=-1` plus specificbootstrap_type settings - `kaggle-auc-binary-submission-bug`: After CV-LB mismatch, discovered that submitting binary 0/1 instead of probabilities causes silent accuracy degradation **Integration pattern**: Claudeception is the "Stage 4: Extract" of the learning loop. Without it, knowledge remains trapped in conversation context and is lost when sessions end. ### 8.2 Memory (Knowledge Graph) — Long-Term Context Storage **What it does**: Stores structured knowledge across sessions using Zettelkasten-style knowledge graph with bidirectional links. **When to use**: - Before starting a new task → query for similar past tasks - After discovering architectural decisions → store as ADR (Architecture Decision Record) - When connecting new learnings to past experiments → create bidirectional links **How it differs from skills**: ``` Memory files: Skills: - Unstructured notes - Structured (YAML + sections) - Session-specific context - Reusable across sessions - Temporary (crystallize or archive) - Persistent - Store "what happened" - Store "how to solve" - Example: s6e2_optuna_key_insights - Example: kaggle-optimal-blending ``` **Lifecycle**: ``` Create (during work) → Reference (in later sessions) → Crystallize (into skill) → Archive ``` ### 8.3 ML-Expert — The Core Knowledge Foundation **What it does**: Comprehensive ML/DL knowledge base covering the full spectrum from data processing to model deployment. Acts as the L1 "core capability" layer. **When it triggers**: Any ML-related task — model training, data preprocessing, feature engineering, hyperparameter tuning, evaluation. **Content structure**: ``` 1. Data Processing & Feature Engineering 2. Traditional ML (scikit-learn, XGBoost, LightGBM, CatBoost) 3. Deep Learning (PyTorch, TensorFlow, architectures) 4. Model Evaluation & Optimization 5. Experiment Management (MLflow, tracking) 6. Domain-Specific patterns ``` **Integration pattern**: ML-Expert is the "Stage 1: Study" foundation. When new ML books or papers are read, their knowledge should be absorbed into ml-expert or spawn new specialized skills. ### 8.4 Kaggle-Competition-Best-Practices — Competition Methodology **What it does**: Comprehensive competition workflow from data exploration to final submission, with accumulated strategies from 4 competitions. **When it triggers**: Starting any Kaggle competition, or needing competition-specific strategies. **Key patterns encoded**: ``` 1. Data Format First — verify data format before any research 2. External Data Validation — validate external datasets before use 3. Feature Boundary Testing — systematic feature engineering with boundary checks 4. Optimal Blending — 80/20 rule for ensemble construction 5. Top Performer Replication — systematic methodology to learn from leaders 6. Submission Workflow — complete pipeline from model to Kaggle submission ``` ### 8.5 Skill-Creator — Skill Quality Assurance **What it does**: Ensures new skills follow proper structure and quality standards. **When to use**: When Claudeception creates a new skill, skill-creator validates: - YAML frontmatter completeness - Description contains specific trigger conditions - Solution has been verified to work - No sensitive information included **Quality criteria checklist**: ``` [ ] Description contains specific trigger conditions [ ] Solution has been verified to work [ ] Content is specific enough to be actionable [ ] Content is general enough to be reusable [ ] No sensitive information (credentials, internal URLs) [ ] Skill doesn't duplicate existing documentation ``` ### 8.6 Continuous-Learning — Session-End Knowledge Review **What it does**: Reviews entire session at completion to identify all extractable knowledge. **When it triggers**: End of session, or when user runs `/claudeception`. **Process**: ``` 1. Review conversation history for extractable knowledge 2. List potential skills with brief justifications 3. Prioritize by value and reusability (typically 1-3 per session) 4. Extract top candidates 5. Report what was created and why ``` ### 8.7 How Skills Interact — The Complete Workflow ``` User starts a new ML task │ ├──▶ ml-expert activated (L1 core knowledge) │ Provides foundational ML concepts and patterns │ ├──▶ kaggle-competition-best-practices activated (L2 domain) │ Provides competition-specific workflow │ ├──▶ memory queried (L3 context) │ Retrieves similar past tasks and lessons learned │ ├──▶ Domain-specific skills triggered as needed │ e.g., catboost-multicore-config, ensemble-model-correlation-trap │ ├──▶ Problem encountered during work │ │ │ ├──▶ search-complex-problems triggers web search │ │ Finds current solutions online │ │ │ ├──▶ investigate performs systematic debugging │ │ Root cause analysis and fix │ │ │ └──▶ Claudeception extracts new skill │ Knowledge crystallized for future use │ └──▶ Session ends │ └──▶ continuous-learning reviews session Final extraction and quality check ``` ### 8.8 Adapting These Skills for Other Agents | Skill Pattern | Core Mechanism | How to Replicate | |---------------|---------------|-----------------| | Claudeception | Self-referential skill creation | Implement a "meta-skill" that can create new skills based on session learnings | | Memory | Persistent file storage with links | Use any structured storage (JSON, markdown, SQLite) with cross-referencing | | ML-Expert | Comprehensive domain knowledge | Start with a broad foundation skill, expand through study + crystallization | | Best-Practices | Workflow methodology | Document processes after each successful project, refine over iterations | | Skill-Creator | Quality validation | Implement schema validation for new skills (required fields, trigger conditions) | | Continuous-Learning | Session review | Run a "retrospective" at end of each session, evaluate what was learned | --- --- ## Part 9: Proactive Evolution — From "做完再看" to "边做边想边调整" Based on comparative analysis with 30+ cutting-edge AI agent research papers (Self-Evolving Agents Survey, SPIRAL, Mem0, Memory-R1, etc.), this section identifies 7 enhancement dimensions that evolve our reactive model into a proactive one. ### 9.1 Enhancement Overview ``` CURRENT STATE ENHANCED STATE ┌─────────────────┐ ┌─────────────────┐ Feedback: │ Outcome only │ ──────────────────▶ │ Process + Outcome│ Planning: │ Reactive only │ ──────────────────▶ │ Proactive Sim │ Exploration: │ Serial only │ ──────────────────▶ │ Parallel Agents │ Consolidation:│ On-demand only │ ──────────────────▶ │ Auto + On-demand │ Retention: │ Growth only │ ──────────────────▶ │ Growth + Forgetting│ Activation: │ Keyword match │ ──────────────────▶ │ Context-aware │ Evaluation: │ Final result │ ──────────────────▶ │ Full trajectory │ └─────────────────┘ └─────────────────┘ ``` ### 9.2 Self-Critique Checkpoint (P0 — Implement Immediately) **Problem**: We only evaluate results after task completion. Errors accumulate through the execution path unchecked. **Solution**: Insert self-evaluation checkpoints at critical decision points. **When to use**: Before any non-trivial implementation step (model selection, feature engineering strategy, ensemble architecture, hyperparameter ranges). **Implementation**: ``` Before executing a plan step, ask: 1. "What is the theoretical basis for this approach?" 2. "What are the top 3 risks?" 3. "What signal would tell me this is wrong BEFORE I finish?" After getting intermediate results, check: 4. "Did any of my predicted risks materialize?" 5. "Is the intermediate result consistent with my expectations?" 6. "Should I continue or pivot?" ``` **Real example**: R11 ensemble training — CatBoost on 2.8M rows was slow and ineffective. A self-critique checkpoint would have asked "Is CatBoost worth the compute cost here?" BEFORE spending hours training it. The answer from past experience (CatBoost struggles with large tabular data) would have redirected effort sooner. **Research basis**: SPIRAL (Symbolic LLM Planning via Grounded and Reflective Search) — dense feedback at every intermediate step, not just sparse terminal rewards. ### 9.3 Simulate-Before-Execute (P0 — Implement Immediately) **Problem**: We jump to implementation without simulating likely outcomes. This leads to expensive wrong directions. **Solution**: Before complex tasks, briefly simulate 2-3 approaches and predict their outcomes. **When to use**: When multiple approaches exist with unclear tradeoffs; when the task involves significant compute time; when past experience suggests common failure modes. **Implementation**: ``` Phase 1: Generate Options (2-3 min) - List 2-3 candidate approaches - For each: best case outcome, worst case outcome, probability estimate Phase 2: Simulate (2-3 min) - For each approach, mentally simulate: * What data path does it take? * Where are the bottlenecks? * What has past experience (skills/memory) shown? Phase 3: Select & Execute - Choose the approach with best expected value - If simulation reveals uncertainty, start with the smallest experiment that would resolve the uncertainty ``` **Real example**: Before R11, simulating the ensemble approach: - LightGBM: Fast, proven on this data, CV ~0.398 — HIGH confidence - XGBoost: Similar to LGB, small improvement likely — MEDIUM confidence - CatBoost: Slow on large tabular, uncertain benefit — LOW confidence → Should have started with LGB-only baseline (R11b), then added models selectively. **Research basis**: SPIRAL's Planner-Simulator-Critic architecture; proactive lookahead vs reactive correction. ### 9.4 Auto-Consolidation (P1 — Next Phase) **Problem**: Skills accumulate as fragments. Consolidation only happens when manually triggered. **Solution**: Periodic automatic skill cluster detection and merge proposals. **Implementation**: Add to session startup routine — every N sessions, scan for: - Clusters of 5+ skills with same prefix → propose merge - Skills not triggered in 30 days → propose archive - Skills with >50% content overlap → propose merge **Research basis**: Mem0's Memory Manager agent (ADD/MERGE/UPDATE/DELETE operations); Memory-R1's active consolidation during inactive periods. ### 9.5 Capability Retention Check (P2 — Quarterly) **Problem**: We measure growth but not forgetting. Old domain capabilities may degrade. **Solution**: Quarterly evaluation of performance on past domain types. **Key metrics from research**: - **Forgetting (FGT)**: Accuracy drop on old tasks after learning new ones - **Backward Transfer (BWT)**: Accuracy improvement on old tasks due to new learning **Research basis**: LifelongAgentBench; FGT/BWT metrics from continual learning literature. ### 9.6 Parallel Exploration (P2 — Use When Appropriate) **Problem**: Serial exploration of approaches wastes time on wrong directions. **Solution**: Use multi-agent Task tool to explore multiple approaches simultaneously. **When to use**: When approaches are independent and each takes significant time. **Implementation**: ``` # Instead of: Approach A → fail → Approach B → fail → Approach C → success (3 days) # Do: Task(Agent1, Approach A) + Task(Agent2, Approach B) + Task(Agent3, Approach C) → Collect results → Merge best elements (1 day) ``` **Research basis**: Population-based evolution; maintaining multiple agent variants. ### 9.7 Multi-Equivalent Descriptions (P1 — Batch Update) **Problem**: Skills activate via keyword matching. If problem description uses different terminology than the skill description, activation fails. **Solution**: Enhance each skill description with multiple equivalent phrasings of the trigger conditions. **Pattern**: ```yaml # Instead of single trigger: description: Use when LightGBM hits iteration limit # Use multiple equivalent triggers: description: | Use when: (1) LightGBM/XGBoost/CatBoost training hits iteration limit, (2) best_iteration equals n_estimators parameter, (3) training loss still decreasing at end of training, (4) early stopping never triggered, (5) model appears underfitting despite high iteration count ``` ### 9.8 Path Efficiency Analysis (P2 — Enhance Claudeception) **Problem**: Session retrospectives only capture "what was learned", not "how efficiently we learned it". **Solution**: Add trajectory-level analysis to claudeception retrospective mode. **Metrics**: - **Recovery Rate**: % of error paths that led to correct recovery - **Repetitiveness Rate**: % of redundant/looping actions - **Tool Productivity**: Ratio of productive tool calls to total calls - **Costliest Wrong Path**: The single most expensive wrong direction and its early warning signals **Research basis**: Agent evaluation frameworks — trajectory metrics vs outcome metrics; Recovery Rate, Repetitiveness Rate from Galileo/Maxim AI evaluation platforms. ### 9.9 Enhancement Priority Matrix | Priority | Enhancement | Effort | Impact | When | |----------|------------|--------|--------|------| | **P0** | Self-Critique Checkpoint | Low (SOP change) | High (-30% wrong paths) | Immediate | | **P0** | Simulate-Before-Execute | Low (SOP change) | High (avoid bad directions) | Immediate | | **P1** | Auto-Consolidation | Medium (script) | Medium (less fragmentation) | Next phase | | **P1** | Multi-Equivalent Descriptions | Low (batch edit) | Medium (better skill activation) | Next phase | | **P2** | Parallel Exploration | Low (use Task tool) | Medium (faster experiments) | As needed | | **P2** | Path Efficiency Analysis | Medium (enhance claudeception) | Medium (better learning) | Next phase | | **P3** | Capability Retention Check | High (re-evaluation) | Long-term (prevent decay) | Quarterly | ### 9.10 Integration with Existing Framework The enhancements integrate at these points in the Five-Stage Learning Loop: ``` Stage 1 (Study) ─── unchanged Stage 2 (Verify) ─── unchanged Stage 3 (Apply) ──┬── Self-Critique Checkpoint (before each major step) ├── Simulate-Before-Execute (before choosing approach) └── Parallel Exploration (when multiple viable approaches exist) Stage 4 (Extract) ─┬── Path Efficiency Analysis (enhanced claudeception) └── Auto-Consolidation (periodic, not just on-demand) Stage 5 (Plan) ───┬── Capability Retention Check (quarterly) └── Multi-Equivalent Descriptions (improve future skill activation) ``` --- ## References - Zhang, L.
