January 2026 (badlogic/pi-mono): Delivered a critical bug fix to stabilize the OpenCode provider RBAC flow. The OpenCode provider's /v1 endpoint previously used the developer role, which caused 400 errors due to incorrect role information. The fix switches to the system role, eliminating the error and improving endpoint reliability. Implemented in commit cceb5908d913209f0e448930e1c8efe8accbb657 and linked to PR #755, with the changelog updated to reflect this normalization. Impact: higher API reliability for OpenCode integrations, reduced incident volume, and smoother downstream interactions. Demonstrates robust RBAC understanding, API debugging, and disciplined change management.

In November 2025, delivered a focused fix in sst/opencode to correct token usage and billing for custom model aliases. The change ensures reasoning tokens are charged at the same rate as output tokens, aligning with the intended pricing model and improving cost accuracy and forecasting. The fix also addresses accounting for cached and reasoning tokens to prevent billing discrepancies. This work reduces cost misstatements for customers using custom model aliases and enhances overall reliability of the pricing pipeline.
