Skill Upgrader
Meta-skill that upgrades any SKILL.md to Decision Theory v5 Hybrid format using 4 parallel Ragie-backed agents.
When to Use
- "Upgrade this skill to v5"
- "Formalize this skill with decision theory"
- "Add MDP structure to this skill"
- "Apply the skill-upgrader to X"
Prerequisites
Ragie RAG with indexed books:
- decision-theory partition: LaValle Planning Algorithms, Sutton & Barto RL
- modal-logic partition: Blackburn Modal Logic, Huth & Ryan Logic in CS
Workflow
Step 1: Setup Session
SESSION=$(date +%Y%m%d-%H%M%S)-upgrade-{skill_name}
mkdir -p thoughts/skill-builds/${SESSION}Step 2: Initialize Blackboard
Create thoughts/skill-builds/{session}/00-blackboard.md:
# Skill Upgrade: {skill_name}
Started: {timestamp}
## Input Skill
{path_to_skill}
## Target Format
Decision Theory v5 Hybrid
## Agent Findings
(Agents append below)
---Step 3: Launch 4 Agents in Parallel
Use Task tool to spawn all 4 agents simultaneously. Each agent:
- Reads the input skill
- Queries Ragie for their specific book
- Appends findings to the blackboard
Agent 1: LaValle Planner
Book: LaValle's "Planning Algorithms" (decision-theory partition) Focus: States, Actions, Transitions
Task(
subagent_type="general-purpose",
prompt="""
INPUT SKILL: {path}
BLACKBOARD: thoughts/skill-builds/{session}/00-blackboard.md
YOUR BOOK: LaValle's "Planning Algorithms" in Ragie partition 'decision-theory'
TASK: Identify MDP structure in the skill.
Query Ragie:uv run python scripts/ragie_query.py -q "MDP state space definition" -p decision-theory uv run python scripts/ragie_query.py -q "action space sequential decisions" -p decision-theory uv run python scripts/ragie_query.py -q "POMDP partial observability" -p decision-theory
Read the input skill and answer:
1. What are the STATES? (phases, modes, tracked info)
2. What are the ACTIONS? (what can agent do in each state)
3. How do TRANSITIONS work? (deterministic or stochastic)
4. Is this POMDP or fully observable?
WRITE to blackboard section: ## Agent 1: States, Actions & Transitions
Format as plain English with LaValle chapter citations. """)
Agent 2: Sutton & Barto Optimizer
Book: Sutton & Barto's "Reinforcement Learning" (decision-theory partition) Focus: Policy, Termination, Value Depends on: Agent 1
Task(subagent_type="general-purpose", prompt=""" INPUT SKILL: {path} BLACKBOARD: thoughts/skill-builds/{session}/00-blackboard.md
YOUR BOOK: Sutton & Barto's "Reinforcement Learning" in Ragie partition 'decision-theory'
WAIT: Read Agent 1's findings from blackboard first.
TASK: Design policy and termination conditions.
Query Ragie:
uv run python scripts/ragie_query.py -q "policy deterministic stochastic" -p decision-theory uv run python scripts/ragie_query.py -q "episodic termination conditions" -p decision-theory uv run python scripts/ragie_query.py -q "reward function design" -p decision-theory
Using Agent 1's states and actions, answer:
1. What's the POLICY? (state → action rules)
2. When does it END? (terminal states, success/failure)
3. What are REWARDS? (goals +, costs -)
4. Which states are HIGH/LOW value?
WRITE to blackboard section: ## Agent 2: Policy & Values
Format as plain English with Sutton & Barto section citations. """)
Agent 3: Blackburn Modal Logician
Book: Blackburn's "Modal Logic" (modal-logic partition) Focus: Constraints (temporal, epistemic, deontic)
Task(subagent_type="general-purpose", prompt=""" INPUT SKILL: {path} BLACKBOARD: thoughts/skill-builds/{session}/00-blackboard.md
YOUR BOOK: Blackburn's "Modal Logic" in Ragie partition 'modal-logic'
TASK: Extract constraints from the skill.
Query Ragie:
uv run python scripts/ragie_query.py -q "temporal logic LTL operators" -p modal-logic uv run python scripts/ragie_query.py -q "epistemic logic knowledge" -p modal-logic uv run python scripts/ragie_query.py -q "deontic logic obligations" -p modal-logic
Read the input skill and identify:
1. TEMPORAL: "must do X before Y" → □, ◇, U
2. EPISTEMIC: "must know X" → K operator
3. DEONTIC: "must/forbidden/may" → O, F, P
4. DYNAMIC: "action causes effect" → [action]
WRITE to blackboard section: ## Agent 3: Constraints
For each constraint:
- Plain English description
- Modal logic notation
- Why it matters
- Blackburn chapter citation """)
Agent 4: Huth & Ryan Verifier
Book: Huth & Ryan's "Logic in Computer Science" (modal-logic partition) Focus: Validation, Safety, Liveness Depends on: Agents 1-3
Task(subagent_type="general-purpose", prompt=""" INPUT SKILL: {path} BLACKBOARD: thoughts/skill-builds/{session}/00-blackboard.md
YOUR BOOK: Huth & Ryan's "Logic in Computer Science" in Ragie partition 'modal-logic'
WAIT: Read Agents 1-3 findings from blackboard first.
TASK: Verify consistency and completeness.
Query Ragie:
uv run python scripts/ragie_query.py -q "safety properties verification" -p modal-logic uv run python scripts/ragie_query.py -q "liveness properties eventually" -p modal-logic uv run python scripts/ragie_query.py -q "model checking CTL" -p modal-logic
Check:
1. SAFETY: What bad things never happen? □¬(bad)
2. LIVENESS: What good things eventually happen? ◇(good)
3. CONSISTENCY: Any contradictions between agents?
4. COMPLETENESS: Any gaps in coverage?
WRITE to blackboard section: ## Agent 4: Verification
Report with ✓/✗ for each property. Overall verdict: PASS or NEEDS_WORK Huth & Ryan section citations. """)
Step 4: Synthesize Final Skill
After all agents complete, read the blackboard and create:
Output: thoughts/skill-builds/{session}/SKILL-upgraded.md
