Generates 10 realistic Claude Code sessions from 5 simulated team members, with multi-step prompts that produce multiple tool calls per session. Useful for populating a demo environment for recordings. Usage: ./scripts/demo-generate.sh [work-dir] Prerequisites: - Plugin installed at user or project scope - .claude/dash0-agent-plugin.local.md in work-dir with target endpoint The script: - Creates a per-project override (.claude/dash0-agent-plugin.local.md) - Swaps git user.name between sessions for multi-user data - Restores original git config on exit (via trap) - Mixes Sonnet and Opus models
Claude Code fires SessionStart on resume, compact, and clear — not just startup. Without a guard, each re-fire overwrites the trace context (clobbering the model field) and re-runs the connectivity check with its user-visible message. Use a sentinel file in sessionDir to skip initialization on subsequent fires. The sentinel is cleaned up with the rest of sessionDir on SessionEnd. Closes #112
Registers a plugin command that prints and opens the Dash0 session URL for the current session. Adds a `session-url` subcommand to the binary that takes session_id via stdin JSON and outputs the full URL. Also forwards script arguments to the binary so subcommands work.
Adds `on-event generate` subcommand that replays fabricated hook events through the real pipeline.Process path, producing spans and matching GitHub App VCS metrics (dash0.gen_ai.vcs.*) with aligned join keys. Supports multiple personas, models, multi-turn sessions, and MCP tool calls. Packaged as a single binary subcommand (Cloud Run friendly).
