| SEP-2640 baseline copy |
Verbatim copy of the SEP text pinned at an August 2026 draft commit, kept so discussion could quote stable text |
The published SEP-2640 and the stable specification |
| Why Skills Over MCP? |
Value proposition and decision guide written while the approach was being argued for |
SEP-2640 Motivation; the README |
| Use Cases |
Use cases that drove the design |
SEP-2640 Motivation |
| Approaches |
Map of the six approaches considered before converging on the convention approach |
Decision log entries 2026-02-21 and 2026-02-26; SEP-2640 |
