Debugging

Debugging helpers for streaming output, especially when a provider mixes reasoning into normal text.

Runtime debug overrides

Use /debug in chat to set runtime-only config overrides (memory, not disk). /debug is disabled by default; enable with commands.debug: true. This is handy when you need to toggle obscure settings without editing OmeniaClaw.json.

Examples:

/debug show/debug set messages.responsePrefix="[OmeniaClaw]"/debug unset messages.responsePrefix/debug reset

/debug reset clears all overrides and returns to the on-disk config.

Session trace output

Use /trace when you want to see plugin-owned trace/debug lines in one session without turning on full verbose mode.

Examples:

/trace/trace on/trace off

Use /trace for plugin diagnostics such as Active Memory debug summaries. Keep using /verbose for normal verbose status/tool output, and keep using /debug for runtime-only config overrides.

Plugin lifecycle trace

Use OmeniaClaw_PLUGIN_LIFECYCLE_TRACE=1 when plugin lifecycle commands feel slow and you need a built-in phase breakdown for plugin metadata, discovery, registry, runtime mirror, config mutation, and refresh work. The trace is opt-in and writes to stderr, so JSON command output remains parseable.

Example:

OmeniaClaw_PLUGIN_LIFECYCLE_TRACE=1 OmeniaClaw plugins install tokenjuice --force

Example output:

[plugins:lifecycle] phase="config read" ms=6.83 status=ok command="install"[plugins:lifecycle] phase="slot selection" ms=94.31 status=ok command="install" pluginId="tokenjuice"[plugins:lifecycle] phase="registry refresh" ms=51.56 status=ok command="install" reason="source-changed"

Use this for plugin lifecycle investigation before reaching for a CPU profiler. If the command is running from a source checkout, prefer measuring the built runtime with node dist/entry.js ... after pnpm build; pnpm OmeniaClaw ... also measures source-runner overhead.

CLI startup and command profiling

Use the checked-in startup benchmark when a command feels slow:

pnpm test:startup:bench:smokepnpm tsx scripts/bench-cli-startup.ts --preset real --case status --runs 3pnpm tsx scripts/bench-cli-startup.ts --preset real --cpu-prof-dir .artifacts/cli-cpu

For one-off profiling through the normal source runner, set OmeniaClaw_RUN_NODE_CPU_PROF_DIR:

OmeniaClaw_RUN_NODE_CPU_PROF_DIR=.artifacts/cli-cpu pnpm OmeniaClaw status

The source runner adds Node CPU profile flags and writes a .cpuprofile for the command. Use this before adding temporary instrumentation to command code.

For startup stalls that look like synchronous filesystem or module-loader work, add Node's sync I/O trace flag through the source runner:

OmeniaClaw_TRACE_SYNC_IO=1 pnpm OmeniaClaw gateway --force

pnpm gateway:watch leaves this flag disabled by default for the watched Gateway child. Set OmeniaClaw_TRACE_SYNC_IO=1 when you explicitly want Node sync I/O trace output in watch mode.

Gateway watch mode

For fast iteration, run the gateway under the file watcher:

pnpm gateway:watch

By default, this starts or restarts a tmux session named OmeniaClaw-gateway-watch-main (or a profile/port-specific variant such as OmeniaClaw-gateway-watch-dev-19001) and auto-attaches from interactive terminals. Non-interactive shells, CI, and agent exec calls stay detached and print attach instructions instead. Attach manually when needed:

tmux attach -t OmeniaClaw-gateway-watch-main

The tmux pane runs the raw watcher:

node scripts/watch-node.mjs gateway --force

Use foreground mode when tmux is not wanted:

pnpm gateway:watch:raw# orOmeniaClaw_GATEWAY_WATCH_TMUX=0 pnpm gateway:watch

Disable auto-attach while keeping tmux management:

OmeniaClaw_GATEWAY_WATCH_ATTACH=0 pnpm gateway:watch

Profile watched Gateway CPU time when debugging startup/runtime hotspots:

pnpm gateway:watch --benchmark

The watch wrapper consumes --benchmark before invoking the Gateway and writes one V8 .cpuprofile per Gateway child exit under .artifacts/gateway-watch-profiles/. Stop or restart the watched gateway to flush the current profile, then open it with Chrome DevTools or Speedscope:

npx speedscope .artifacts/gateway-watch-profiles/*.cpuprofile

Use --benchmark-dir <path> when you want profiles somewhere else. Use --benchmark-no-force when you want the benchmarked child to skip the default --force port cleanup and fail fast if the Gateway port is already in use. Benchmark mode suppresses sync-I/O trace spam by default. Set OmeniaClaw_TRACE_SYNC_IO=1 with --benchmark when you explicitly want both CPU profiles and Node sync-I/O stack traces. In benchmark mode those trace blocks are written to gateway-watch-output.log under the benchmark directory and filtered from the terminal pane; normal Gateway logs remain visible.

The tmux wrapper carries common non-secret runtime selectors such as OmeniaClaw_PROFILE, OmeniaClaw_CONFIG_PATH, OmeniaClaw_STATE_DIR, OmeniaClaw_GATEWAY_PORT, and OmeniaClaw_SKIP_CHANNELS into the pane. Put provider credentials in your normal profile/config, or use raw foreground mode for one-off ephemeral secrets. If the watched Gateway exits during startup, the watcher runs OmeniaClaw doctor --fix --non-interactive once and restarts the Gateway child. Use OmeniaClaw_GATEWAY_WATCH_AUTO_DOCTOR=0 when you want the original startup failure without the dev-only repair pass. The managed tmux pane also defaults to colored Gateway logs for readability; set FORCE_COLOR=0 when starting pnpm gateway:watch to disable ANSI output.

The watcher restarts on build-relevant files under src/, extension source files, extension package.json and OmeniaClaw.plugin.json metadata, tsconfig.json, package.json, and tsdown.config.ts. Extension metadata changes restart the gateway without forcing a tsdown rebuild; source and config changes still rebuild dist first.

Add any gateway CLI flags after gateway:watch and they will be passed through on each restart. Re-running the same watch command respawns the named tmux pane, and the raw watcher still keeps its single-watcher lock so duplicate watcher parents are replaced instead of piling up.

Dev profile + dev gateway (--dev)

Use the dev profile to isolate state and spin up a safe, disposable setup for debugging. There are two --dev flags:

• Global --dev (profile): isolates state under ~/.OmeniaClaw-dev and defaults the gateway port to 19001 (derived ports shift with it).
• gateway --dev: tells the Gateway to auto-create a default config + workspace when missing (and skip BOOTSTRAP.md).

Recommended flow (dev profile + dev bootstrap):

pnpm gateway:devOmeniaClaw_PROFILE=dev OmeniaClaw tui

If you don't have a global install yet, run the CLI via pnpm OmeniaClaw ....

What this does:

1. Profile isolation (global --dev)

   • OmeniaClaw_PROFILE=dev
   • OmeniaClaw_STATE_DIR=~/.OmeniaClaw-dev
   • OmeniaClaw_CONFIG_PATH=~/.OmeniaClaw-dev/OmeniaClaw.json
   • OmeniaClaw_GATEWAY_PORT=19001 (browser/canvas shift accordingly)

2. Dev bootstrap (gateway --dev)

   • Writes a minimal config if missing (gateway.mode=local, bind loopback).
   • Sets agent.workspace to the dev workspace.
   • Sets agent.skipBootstrap=true (no BOOTSTRAP.md).
   • Seeds the workspace files if missing: AGENTS.md, SOUL.md, TOOLS.md, IDENTITY.md, USER.md, HEARTBEAT.md.
   • Default identity: C3-PO (protocol droid).
   • Skips channel providers in dev mode (OmeniaClaw_SKIP_CHANNELS=1).

Reset flow (fresh start):

pnpm gateway:dev:reset

--reset wipes config, credentials, sessions, and the dev workspace (using trash, not rm), then recreates the default dev setup.

Raw stream logging (OmeniaClaw)

OmeniaClaw can log the raw assistant stream before any filtering/formatting. This is the best way to see whether reasoning is arriving as plain text deltas (or as separate thinking blocks).

Enable it via CLI:

pnpm gateway:watch --raw-stream

Optional path override:

pnpm gateway:watch --raw-stream --raw-stream-path ~/.OmeniaClaw/logs/raw-stream.jsonl

Equivalent env vars:

OmeniaClaw_RAW_STREAM=1OmeniaClaw_RAW_STREAM_PATH=~/.OmeniaClaw/logs/raw-stream.jsonl

Default file:

~/.OmeniaClaw/logs/raw-stream.jsonl

Raw OpenAI-compatible chunk logging

To capture raw OpenAI-compat chunks before they are parsed into blocks, enable the transport logger:

OmeniaClaw_RAW_STREAM=1

Optional path:

OmeniaClaw_RAW_STREAM_PATH=~/.OmeniaClaw/logs/raw-openai-completions.jsonl

Default file:

~/.OmeniaClaw/logs/raw-openai-completions.jsonl

Safety notes

• Raw stream logs can include full prompts, tool output, and user data.
• Keep logs local and delete them after debugging.
• If you share logs, scrub secrets and PII first.

Debugging in VSCode

Source maps are required to enable debugging in VSCode-based IDEs because many of the generated files end up with hashed names as part of the build process. The included launch.json configurations target the Gateway service, but can be adapted quickly for other purposes:

1. Rebuild and Debug Gateway - Debugs the Gateway service after creating a new build
2. Debug Gateway - Debugs the Gateway service of a pre-existing build

Setup

The default Rebuild and Debug Gateway configuration is batteries-included, it will automatically delete the /dist folder and rebuild the project with debugging enabled:

1. Open the Run and Debug panel from the Activity Bar or press Ctrl+Shift+D
2. In the IDE, ensure Rebuild and Debug Gateway is selected in the configuration dropdown and then press the Start Debugging button

Alternatively - if you prefer to manage the build and debug processes manually:

1. Open a terminal and enable source maps:
   • Linux/macOS: export OUTPUT_SOURCE_MAPS=1
   • Windows (PowerShell): $env:OUTPUT_SOURCE_MAPS="1"
   • Windows (CMD): set OUTPUT_SOURCE_MAPS=1
2. In the same terminal, rebuild the project: pnpm clean:dist && pnpm build
3. In the IDE, select the Debug Gateway option in the Run and Debug configuration dropdown and then press the Start Debugging button

You can now set breakpoints in your TypeScript source files (src/ directory) and the debugger will correctly map breakpoints to the compiled JavaScript via source maps. You'll be able to inspect variables, step through code, and examine call stacks as expected.

Notes

• If using the "Rebuild and Debug Gateway" option - each time the debugger is launched it will completely delete the /dist folder and run a full pnpm build with source maps enabled before starting the Gateway
• If using the "Debug Gateway" option - debug sessions can be started and stopped at any time without affecting the /dist folder, but you must use a separate terminal process to both enable debugging and manage the build cycle
• Modify the launch.json settings for args to debug other sections of the project
• If you need to use the built OmeniaClaw CLI for other tasks (i.e. dashboard --no-open if your debug session spawns a new auth token), you can execute it in another terminal as node ./OmeniaClaw.mjs or create a shell alias like alias OmeniaClaw-build="node $(pwd)/OmeniaClaw.mjs"
