opencode-troubleshooting

A troubleshooting guide for OpenCode, an AI coding assistant available as a command-line tool, terminal interface, web interface, and desktop app. It covers logs, stored data, connection problems, plugins, models, and common startup or authentication errors.

In plain words
What is it for?
Use it to inspect logs, resolve desktop and CLI issues, fix authentication or provider errors, troubleshoot plugins and caches, and investigate platform-specific problems.
Why use it?
It gives developers a structured way to diagnose why OpenCode will not start, cannot connect, cannot find a model, or has an unresponsive interface. It points to logs and targeted fixes before suggesting a storage reset.

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 C, and why

opencode-troubleshooting scanned grade C with 2 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 yesterday.

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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

OpenCode Troubleshooting

📚 Official Docs: For the latest information, always refer to the official documentation: https://opencode.ai/docs/troubleshooting/

OpenCode is an AI-powered coding assistant available as a CLI, TUI, web interface, and desktop app. When something goes wrong — the app won't start, models fail to load, authentication breaks, or the UI is unresponsive — this skill provides comprehensive diagnostic and resolution procedures. Start by checking logs and storage, then work through the specific issue category.

Logs

Log files are the first place to look when diagnosing any issue with OpenCode. They contain detailed information about startup, provider connections, API calls, errors, and internal state transitions.

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.
