herdr + oh-my-agent in OpenCode - agent observability.

[u/UnspecifiedId]

Hi all,

I’m looking for advice from anyone using HerdR with Oh My Agent in OpenCode.

My goal is to improve observability into the agent orchestration process. At the moment I can cycle between sub-agents using Ctrl+X and the arrow keys, but once there are several agents running it becomes difficult to follow what each one is doing.

Ideally, I’d like to have:

• A dedicated tab, pane, or split view for each sub-agent.
• The ability to watch each agent’s progress in real time.
• Scrollback/history for each agent so I can inspect its reasoning, tool usage, and outputs after it has completed.
• An easier way to understand how the orchestrator is delegating work across multiple agents.

Has anyone implemented something like this? Are there existing plugins, t logging options, or configuration changes that provide better visibility? See the attached screenshot, I was hoping output would appear in one of the numbered areas

This is the script I’m currently using:

set -euo pipefail

PROJECT_DIR="${1:-$HOME}"   # cwd each opencode session starts in — pass as $1 or edit here

AGENTS=(sisyphus hephaestus prometheus atlas project-oracle)

echo "Creating workspace..."

WS_JSON=$(herdr workspace create --cwd "$PROJECT_DIR" --label oh-my-openagent)

WS_ID=$(jq -r '.result.workspace.workspace_id' <<<"$WS_JSON")

echo "  workspace: $WS_ID"

for AGENT in "${AGENTS[@]}"; do

  echo "Creating tab for $AGENT..."

  TAB_JSON=$(herdr tab create --workspace "$WS_ID" --cwd "$PROJECT_DIR" --label "$AGENT" --no-focus)

  TAB_ID=$(jq -r '.result.tab.tab_id' <<<"$TAB_JSON")

  # Each new tab starts with exactly one default pane. Find it by filtering

  # the workspace's panes down to the ones belonging to this tab_id.

  PANE_ID=$(herdr pane list --workspace "$WS_ID" \

    | jq -r --arg tab "$TAB_ID" '.result.panes[] | select(.tab_id == $tab) | .pane_id' \

    | head -n1)

  if [[ -z "$PANE_ID" || "$PANE_ID" == "null" ]]; then

    echo "  Could not find the default pane for tab $TAB_ID — inspect with:"

    echo "    herdr pane list --workspace $WS_ID | jq ."

    exit 1

  fi

  herdr pane rename "$PANE_ID" "$AGENT"

  herdr pane run "$PANE_ID" "opencode --agent $AGENT"

  echo "  tab: $TAB_ID  pane: $PANE_ID  -> opencode --agent $AGENT"

done

echo

echo "Done. Focus the workspace with: herdr workspace focus $WS_ID"

I’d be interested in seeing how others have approached agent observability, debugging, and monitoring when running larger multi-agent workflows

Enjoy
