Progressive Disclosure Meta-Skill
Metadata
Skill Name: Progressive Disclosure Manager Type: Meta-skill Version: 1.0.0 Purpose: Manages the progressive disclosure of skill content to optimize context window usage Triggers: Invoked when determining which level of skill content to load Dependencies: None Context Cost: Low (metadata only), Medium (with instructions), High (full resources)
Quick Summary: This meta-skill determines which level of a skill (metadata, instructions, or resources) should be loaded based on task relevance, ensuring only necessary context occupies the context window.
Instructions
Overview
The Progressive Disclosure Manager operates on a three-tier system for skill content:
- Level 1: Metadata - Basic information about what the skill does
- Level 2: Instructions - How to use the skill and when to apply it
- Level 3: Resources - Detailed implementation guidance, examples, and edge cases
Decision Framework
Use this decision tree to determine which level to load:
┌─────────────────────────────────────┐
│ Is skill potentially relevant? │
│ (keywords, topic match) │
└─────────┬───────────────────────────┘
│
├─ NO ──> Skip entirely
│
├─ MAYBE ──> Load METADATA only
│ • Skill name
│ • One-line description
│ • Triggers/keywords
│
├─ YES ──> Load INSTRUCTIONS
│ • How to use it
│ • When to apply it
│ • Basic examples
│
└─ CRITICAL ──> Load FULL RESOURCES
• Detailed algorithms
• Edge case handling
• Complete examples
• Performance considerations
Relevance Detection Algorithm
Step 1: Extract Context Signals
- Parse user query for keywords and intent
- Identify task type (implementation, debugging, analysis, etc.)
- Assess complexity level (simple, moderate, complex)
Step 2: Score Skill Relevance
For each available skill, calculate relevance score:
relevance_score = (
keyword_match * 0.3 + # Direct keyword overlap
topic_similarity * 0.3 + # Semantic topic alignment
task_type_match * 0.2 + # Does skill type match task?
complexity_alignment * 0.2 # Skill complexity matches need?
)
Step 3: Load Appropriate Level
if relevance_score < 0.2:
return None # Skip skill entirely
elif relevance_score < 0.5:
return "metadata" # Light context
elif relevance_score < 0.8:
return "instructions" # Medium context
else:
return "resources" # Full context
Usage Examples
Example 1: User asks about UMAP embeddings
Query: "How do I optimize UMAP for large datasets?"
Analysis:
- Keywords: "UMAP", "optimize", "large datasets"
- Task type: Performance optimization
- Complexity: Moderate to high
Skills evaluated:
umap-optimizationskill → Score: 0.9 → Load FULL RESOURCESdata-processingskill → Score: 0.4 → Load METADATA onlyneural-networksskill → Score: 0.1 → SKIP
Example 2: User asks about string manipulation
Query: "Convert this string to uppercase"
Analysis:
- Keywords: "string", "uppercase"
- Task type: Simple transformation
- Complexity: Low
Skills evaluated:
text-processingskill → Score: 0.6 → Load INSTRUCTIONSregex-patternsskill → Score: 0.3 → Load METADATA onlynlp-pipelineskill → Score: 0.1 → SKIP
Integration with Task Execution
# Before starting task
1. Parse user request
2. Identify candidate skills
3. For each skill:
a. Calculate relevance score
b. Load appropriate level
c. Add to context window
4. Proceed with task using loaded skills
# During task execution
- If need more detail → Upgrade skill level (metadata → instructions → resources)
- If skill unused → Downgrade or remove from context
- Monitor context window usage → Prioritize high-relevance skills
Context Window Management
Budget Allocation Strategy:
Total Context: 200K tokens
Reserved:
- User query & history: 10-20K tokens
- Code being edited: 20-40K tokens
- Tool outputs: 10-30K tokens
- Response generation: 10-20K tokens
Available for skills: ~100-120K tokens
Allocation:
- High relevance (0.8+): Up to 20K tokens each (full resources)
- Medium relevance (0.5-0.8): Up to 5K tokens each (instructions)
- Low relevance (0.2-0.5): Up to 1K tokens each (metadata)

4. Dynamic Level Upgrading
When to upgrade skill level during execution:
class SkillManager:

self.loaded_skills = {} # skill_name -> current_level
self.usage_count = {} # skill_name -> times referenced
def upgrade_skill_if_needed(self, skill_name: str):

"""Track when a skill is referenced."""
self.usage_count[skill_name] = self.usage_count.get(skill_name, 0) + 1
self.upgrade_skill_if_needed(skill_name)
5. Context Window Monitoring
Real-time context management:
class ContextWindowManager:
def __init__(self, max_tokens: int = 200000):
self.max_tokens = max_tokens
self.reserved_tokens = 60000 # For query, code, responses
self.available_tokens = max_tokens - self.reserved_tokens

Calculate efficiency score.

7. Skill Dependency Resolution
Some skills depend on others. Handle dependencies carefully:
def resolve_dependencies(skill: Dict, all_skills: Dict) -> List[str]:
"""
Resolve skill dependencies and determine what to load.
Returns list of skill names to load (including dependencies).
"""
to_load = [skill["name"]]
dependencies = skill.get("dependencies", [])
for dep_name in dependencies:
if dep_name in all_skills:
# Recursively resolve
to_load.extend(resolve_dependencies(all_skills[dep_name], all_skills))
# Remove duplicates, preserve order
return list(dict.fromkeys(to_load))
def load_with_dependencies(
skill_name: str,
relevance_score: float,
all_skills: Dict,
context_manager: ContextWindowManager
) -> Dict[str, str]:
"""
Load skill with its dependencies at appropriate levels.
Returns dict mapping skill_name to loaded content.
"""
skill = all_skills[skill_name]
deps = resolve_dependencies(skill, all_skills)
loaded_content = {}
# Main skill gets level based on relevance
main_level = context_manager.determine_level(relevance_score)
for dep_skill_name in deps:
if dep_skill_name == skill_name:
# Main skill
level = main_level
else:
# Dependencies get loaded at lower level (metadata/instructions only)
level = "metadata" if main_level == "instructions" else "instructions"
# Check budget
if context_manager.can_load_level(dep_skill_name, level):
loaded_content[dep_skill_name] = load_skill_level(
f".claude/skills/{dep_skill_name}/skill.md",
level
)
context_manager.current_usage[dep_skill_name] = (
context_manager.estimate_level_cost(dep_skill_name, level)
)
return loaded_content
8. Caching Strategy
Cache loaded skills to avoid re-parsing:
from functools import lru_cache
import hashlib
from typing import Tuple
class SkillCache:
def __init__(self, max_size: int = 100):
self.cache = {} # (skill_path, level, file_hash) -> content
self.max_size = max_size
self.access_count = {} # key -> count
def get_file_hash(self, file_path: str) -> str:
"""Get hash of file for cache invalidation."""
with open(file_path, 'rb') as f:
return hashlib.md5(f.read()).hexdigest()
def get(self, skill_path: str, level: str) -> str | None:
"""Get cached skill content if available and valid."""
file_hash = self.get_file_hash(skill_path)
key = (skill_path, level, file_hash)
if key in self.cache:
self.access_count[key] = self.access_count.get(key, 0) + 1
return self.cache[key]
return None
def set(self, skill_path: str, level: str, content: str):
"""Cache skill content."""
file_hash = self.get_file_hash(skill_path)
key = (skill_path, level, file_hash)
# Evict least-used if at capacity
if len(self.cache) >= self.max_size:
least_used = min(self.access_count.items(), key=lambda x: x[1])[0]
del self.cache[least_used]
del self.access_count[least_used]
self.cache[key] = content
self.access_count[key] = 1
Testing Guidelines
Test Cases
Test relevance scoring:
- High relevance query → Loads full resources
- Medium relevance → Loads instructions only
- Low relevance → Loads metadata only
- No relevance → Skips skill
Test context window management:
- Multiple skills fit within budget
- Skills exceed budget → Prioritization kicks in
- Dynamic upgrading when skill heavily used
Test dependency resolution:
- Skill with dependencies loads deps at lower level
- Circular dependencies handled gracefully
- Missing dependencies don't break loading
Test caching:
- Same skill+level loaded from cache
- File changes invalidate cache
- LRU eviction works correctly

# 4. Prioritize and load
prioritized = context_mgr.prioritize_skills(scored_skills)

# Check cache first
cached = skill_cache.get(skill["path"], skill["level"])
