handoff-resume

handoff-resume is a skill for Claude Code, Codex from FlorianBruniaux/claude-code-plugins. It costs 40 tokens per session (300 once invoked), scanned A, original, MIT.

A handoff loader that reads a document describing unfinished work, including its scope, files, discoveries, completed work, status, and next steps. It confirms your understanding before allowing work to continue.

In plain words
What is it for?
Use it to reopen a previous work session from a handoff file and review the proposed next steps.
Why use it?
It lets a new session resume from documented progress instead of reconstructing the task from scratch.

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

handoff-resume 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 yesterday.

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.

What it actually says

Read and load the handoff document at $ARGUMENTS[0].

Steps

  1. Read the file at the provided path. If the path does not exist, list files in claudedocs/handoffs/ and ask the user which one to load.

  2. Parse and confirm:

    • Task and scope
    • Files involved (with line numbers)
    • Key discoveries
    • Work completed so far
    • Current status
    • Next steps (ordered)
  3. Confirm understanding: Summarize what you have loaded in 3-5 bullet points. Ask: "Should I proceed with the next step, or do you want to adjust the plan first?"

  4. Do not start working until the user confirms. The confirmation step is mandatory.

Notes

  • If the handoff file references commits (commit: abc1234), note them but do not re-run the work.
  • If next steps are unclear or conflicting, flag it before proceeding.
  • The "Work Done" section is the authoritative record of what has been completed. Trust it.

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.
