Challenge an architecture bet, 10x scaling plan or rebuild vs buy. Use whenever asked or /c-level-agents:cto-review.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /c-level-agents:cto-review — CTO Forcing Questions
**Command:** `/c-level-agents:cto-review <plan>`
Pressure-tests architecture and engineering scaling decisions. Six questions to surface the next scaling cliff before you hit it.
## When to Run
- Before approving a major architecture change
- Before doubling the engineering team
- Before a build-vs-buy decision > $100K/year
- When a system is showing reliability stress (SLOs missed)
- Before committing to a new platform / language / DB
## The Six CTO Questions
### 1. Scaling Cliff
**Where does the current architecture break, in terms of users / requests / data volume?**
- Be specific. "It breaks at 10× current load because the primary DB writes saturate."
- If you don't know, run a load test before deciding.
### 2. Tech Debt Inventory
**What's the top tech debt item, what's it costing per week, and when does it become blocking?**
```bash
python ${CLAUDE_PLUGIN_ROOT}/vendor/c-level-advisor/cto-advisor/scripts/tech_debt_analyzer.py
```
### 3. Team Scaling
**For each open req, what's the ramp time and contribution model?**
```bash

How to install
mdr add alirezarezvani/claude-skills/cto-review@sha256:6a9f8953f0e11949The line at the top of this page pins the label git:20261103.6278f73, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
