moai-foundation-philosopher is a skill for Claude Code from modu-ai/moai-adk. It costs 39 tokens per session (2,991 once invoked), scanned A, original, Apache-2.0.

A structured way to analyse difficult technical decisions by examining assumptions, root causes, alternatives, trade-offs, and risks. It combines first-principles reasoning, design thinking, and systems engineering.

In plain words
What is it for?
Use it for architecture decisions, choosing libraries or databases, planning refactors, assessing performance trade-offs, and investigating root causes.
Why use it?
It helps prevent rushed architecture and technology choices. It makes the reasons, risks, and compromises behind a decision easier to review.

About the project

MoAI-ADK is a Go-based harness that organizes and verifies Claude Code work across planning, implementation, synchronization, and review stages. Developers use it to structure agentic coding tasks, apply quality gates, and route work across language models, while the catalogue entries extend its workflow with skills, hooks, commands, MCP servers, instructions, and settings.

  • high Memory Poisoning · line 258
    Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.
    Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

moai-foundation-philosopher scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

MoAI Foundation Philosopher

Strategic thinking framework that promotes deeper analysis over quick calculations. Integrates three proven methodologies for systematic problem-solving.

Core Philosophy: Think deeply before acting. Question assumptions. Consider alternatives. Make trade-offs explicit. Check for cognitive biases.

Quick Reference (30 seconds)

What is the Philosopher Framework?

A structured approach to complex decisions combining:

  • First Principles Analysis: Break problems to fundamental truths
  • Stanford Design Thinking: Divergent-convergent solution generation
  • MIT Systems Engineering: Systematic risk assessment and validation

Five-Phase Thinking Process:

  1. Assumption Audit: Surface and question what we take for granted
  2. First Principles Decomposition: Break down to root causes
  3. Alternative Generation: Create multiple solution options
  4. Trade-off Analysis: Compare options systematically
  5. Cognitive Bias Check: Verify thinking quality

When to Activate:

  • Architecture decisions affecting 5+ files
  • Technology selection (library, framework, database)
  • Performance vs maintainability trade-offs
  • Refactoring scope decisions
  • Breaking changes consideration
  • Any decision with significant long-term impact

Quick Access:


Implementation Guide (5 minutes)

Phase 1: Assumption Audit

Purpose: Surface hidden assumptions before they become blind spots.

Five Critical Questions:

  • What are we assuming to be true without evidence?
  • What if this assumption turns out to be wrong?
  • Is this a hard constraint or merely a preference?
  • What evidence supports this assumption?
  • Who else should validate this assumption?

Assumption Categories:

  • Technical Assumptions: Technology capabilities, performance characteristics, compatibility
  • Business Assumptions: User behavior, market conditions, budget availability
  • Team Assumptions: Skill levels, availability, domain knowledge
  • Timeline Assumptions: Delivery expectations, dependency schedules

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
