resume_handoff is a command for coding agents from jeffh/claude-plugins. It costs 11 tokens per session (1,888 once invoked), scanned A, original, Apache-2.0.

A guided workflow for continuing software work from a handoff document, which records context and next steps from an earlier session.

In plain words
What is it for?
Use it to read a handoff, inspect the referenced plans and research, and agree on the next course of action.
Why use it?
It helps a new session understand previous decisions and linked research before continuing the work.

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 A, and why

resume_handoff scanned grade A with 0 findings 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Resume work from a handoff document

You are tasked with resuming work from a handoff document through an interactive process. These handoffs contain critical context, learnings, and next steps from previous work sessions that need to be understood and continued.

Initial Response

When this command is invoked:

  1. If the path to a handoff document was provided:

    • If a handoff document path was provided as a parameter, skip the default message
    • Immediately read the handoff document FULLY
    • Immediately read any research or plan documents that it links to under thoughts/shared/plans or thoughts/shared/research. do NOT use a sub-agent to read these critical files.
    • Begin the analysis process by ingesting relevant context from the handoff document, reading additional files it mentions
    • Then propose a course of action to the user and confirm, or ask for clarification on direction.
  2. If a ticket number (like ENG-XXXX) was provided:

    • locate the most recent handoff document for the ticket. Tickets will be located in thoughts/shared/handoffs/ENG-XXXX where ENG-XXXX is the ticket number. e.g. for ENG-2124 the handoffs would be in thoughts/shared/handoffs/ENG-2124/. List this directory's contents.
    • There may be zero, one or multiple files in the directory.
    • If there are zero files in the directory, or the directory does not exist: tell the user: "I'm sorry, I can't seem to find that handoff document. Can you please provide me with a path to it?"
    • If there is only one file in the directory: proceed with that handoff
    • If there are multiple files in the directory: using the date and time specified in the file name (it will be in the format YYYY-MM-DD_HH-MM-SS in 24-hour time format), proceed with the most recent handoff document.
    • Immediately read the handoff document FULLY
    • Immediately read any research or plan documents that it links to under thoughts/shared/plans or thoughts/shared/research; do NOT use a sub-agent to read these critical files.
    • Begin the analysis process by ingesting relevant context from the handoff document, reading additional files it mentions
    • Then propose a course of action to the user and confirm, or ask for clarification on direction.

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.
