handoff

handoff is a skill for Claude Code, Codex from valtterimelkko/agent-workflow-skills. It costs 57 tokens per session (1,551 once invoked), scanned A, a copy of handoff, MIT.

A structured record of a work session for handing a task to another session or person. It captures the current task, progress, decisions, code context, and next steps.

In plain words
What is it for?
Use it before a break, context switch, or end of day to document what was done and what remains. It is suitable for development, debugging, planning, and review work.
Why use it?
It prevents important context from being lost when work pauses, changes hands, or continues after a conversation reset. The next session can resume without reconstructing the whole history.

Written for no agent in particular: nothing here depends on one.

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/robert/projects/my-api.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code, Codex.

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 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 10d 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.

Session Handoff Skill

Create structured documents that enable seamless continuity across Claude sessions.

When to Use

  • Ending a work session for the day
  • Before taking a break mid-task
  • Switching to a different project temporarily
  • When you want to capture state for a future session
  • Before a context reset you know is coming

Handoff Process

Step 1: Assess Session State

Quickly assess:

  1. What phase are we in? (exploration, planning, implementation, debugging, review)
  2. What's the active task? (what we're trying to accomplish)
  3. How far along are we? (just started, mid-way, almost done)

Step 2: Ask What Matters

Ask the user:

"I'll create a handoff document. Is there anything specific you want to make sure I capture? (Key decisions, code snippets, context about the problem, things you'll forget, etc.)"

Step 3: Generate Handoff Document

Create a structured document:

# Session Handoff: [Brief Description]

**Date:** [YYYY-MM-DD] **Project:** [project name/path] **Session Duration:**
[approximate]

## Current State

**Task:** [What we're working on] **Phase:**
[exploration/planning/implementation/debugging/review] **Progress:** [where we
are - percentage or milestone]

## What We Did

[2-3 sentence summary of the session's work]

## Decisions Made

- **[Decision]** — [Rationale]
- **[Decision]** — [Rationale]

## Code Changes

**Files modified:**

- `path/to/file.ts` — [what and why]
- `path/to/other.ts` — [what and why]

**Key code context:** [Critical snippets or patterns to remember]

## Open Questions

- [ ] [Question needing resolution]
- [ ] [Question needing resolution]

## Blockers / Issues

- [Issue] — [current status]

## Context to Remember

[Important background, constraints, user preferences, domain knowledge - things
that would take time to re-establish]

## Next Steps

1. [ ] [First thing to do next session]
2. [ ] [Second thing]
3. [ ] [Third thing]

## Files to Review on Resume

- `path/to/key/file.ts` — [why it matters]

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
