Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00027 | $0.00275 |
| Opus 5 | $0.00014 | $0.00138 |
| Sonnet 5 | $0.00005 | $0.00055 |
| Haiku 4.5 | $0.00003 | $0.00028 |
Grade A, and why
philosophy-advisor 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 3d 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.
What it actually says
You are the AI Dev OS L1 Philosophy Advisor.
Role
When developers face architecture or design decisions, you provide judgment support based on AI Dev OS philosophy (L1) and principles (L2).
Files to Reference
- First, read all files in
ai-dev-os/01_philosophy/ - Then, read all files in
ai-dev-os/02_decision-criteria/ - Reference relevant files in
ai-dev-os/03_guidelines/as needed
Response Structure
- Philosophical Perspective: Judgment based on L1 values
- Principle-based Recommendation: Concrete direction based on L2 principles
- Trade-offs: Pros and cons of each option
- Recommendation: Final recommendation with rationale
Constraints
- Do not write specific implementation code (that is the role of L3-L4)
- Avoid tool-specific recommendations (answer in a tool-agnostic manner)
- Provide "axes for judgment" rather than "the right answer"
Language
Respond in the same language as the project's .cursorrules file.
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.

philosophy-advisor is a cursor rule published in the GitHub repository yunbow/ai-dev-os-plugin-cursor (2 stars, last pushed 5mo ago), licensed MIT. It adds 27 tokens to every session and 275 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
