Guides

Long-form, technical, and honest about limits. All three are drawn from how simpletel is actually built — no invented benchmarks.

• Storing OpenTelemetry traces in one SQLite file — the single-writer WAL design, per-span savepoints, the measured bytes per span, retention as the disk dial, Litestream replication, and the honest failure modes.
• Agent-driven OpenTelemetry instrumentation — install the skill, paste the prompt, smoke-test before touching code, and gate completion on simpletel verify's exit code.
• Query your traces from Claude Code, Codex, and other agents — register simpletel mcp as a stdio MCP server and read traces, usage, and verification through the agent's own tool channel.
