OpenCode

OpenCode has native OpenTelemetry support with the same event structure as Claude Code.

Automatic Setup

flowstate-telemetry install --tool opencode

This configures plugins and environment in ~/.config/opencode/opencode.json.

Manual Setup

Add the OTel environment variables to your shell profile (~/.zshrc or ~/.bashrc):

export OTEL_EXPORTER_OTLP_ENDPOINT="https://otel.flowstate.inc"
export OTEL_EXPORTER_OTLP_HEADERS="x-flowstate-key=YOUR_TELEMETRY_KEY"

What Gets Captured

Event	OTel Name	Data Collected
User prompt	opencode.user_prompt	Prompt text, session ID
API request	opencode.api_request	Model, input/output/cache tokens, cost, duration
Tool result	opencode.tool_result	Tool name, success/failure, duration
API error	opencode.api_error	Error details

TIP

OpenCode captures prompt content by default — there is no opt-in flag. It mirrors the Claude Code OTel event structure, providing the same rich metadata for session aggregation and classification.
