continue-handoff

continue-handoff is a command for coding agents from vanzan01/claude-code-sub-agent-collective. It costs 0 tokens per session (716 once invoked), scanned B, original, MIT.

A command that checks whether an interrupted agent handoff has pending delegation information in `.claude/handoff/NEXT_ACTION.json`.

In plain words
What is it for?
Use it to inspect pending handoffs, view the target agent and context, and resume the next workflow step.
Why use it?
It shows where a paused handoff stopped and which agent should continue it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

continue-handoff scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Continue Agent Handoff Workflow

Resume an interrupted agent handoff workflow by checking for pending delegation context.

What This Does

Checks for pending handoff context and resumes the workflow where it left off:

  • Reads .claude/handoff/NEXT_ACTION.json for pending delegations
  • Displays current handoff status and target agent
  • Provides commands to continue the workflow
  • Shows recent handoff logs for context

Usage

Simply run this command and it will check current state and provide next steps.

Check Current Status

# Check if there's a pending handoff
if [ -f .claude/handoff/NEXT_ACTION.json ]; then
  echo "📋 PENDING HANDOFF FOUND:"
  cat .claude/handoff/NEXT_ACTION.json | jq '.'
  echo ""
  echo "🎯 NEXT ACTION:"
  echo "Use the $(cat .claude/handoff/NEXT_ACTION.json | jq -r '.target_agent') subagent to continue the workflow."
else
  echo "✅ No pending handoffs - workflow is clear"
fi

Resume Workflow

# Get target agent from context file
TARGET_AGENT=$(cat .claude/handoff/NEXT_ACTION.json | jq -r '.target_agent' 2>/dev/null)
CONTEXT=$(cat .claude/handoff/NEXT_ACTION.json | jq -r '.context' 2>/dev/null)

if [ -n "$TARGET_AGENT" ] && [ "$TARGET_AGENT" != "null" ]; then
  echo "🚀 RESUMING WORKFLOW:"
  echo "Target Agent: $TARGET_AGENT"
  echo "Context: $CONTEXT"
  echo ""
  echo "📝 COMMAND TO CONTINUE:"
  echo "Use the $TARGET_AGENT subagent to continue from the previous handoff context."
else
  echo "❌ No valid handoff context found"
fi

When to Use

  • After Interruption: When workflow was stopped mid-execution
  • Session Restart: After closing and reopening Claude Code
  • Network Issues: After connection problems during handoffs
  • Manual Break: When you manually stopped to check something
  • Debugging: To see current workflow state

What You'll See

If Handoff Pending:

{
  "timestamp": "2025-08-11T14:55:18+08:00",
  "action": "delegate",
  "target_agent": "task-orchestrator",

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
