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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.01551 |
| Opus 5 | $0.00028 | $0.00776 |
| Sonnet 5 | $0.00011 | $0.00310 |
| Haiku 4.5 | $0.00006 | $0.00155 |
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.
This is a copy
97% identical to handoff — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 231 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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:
- What phase are we in? (exploration, planning, implementation, debugging, review)
- What's the active task? (what we're trying to accomplish)
- 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.
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.

handoff is a skill published in the GitHub repository valtterimelkko/agent-workflow-skills (2 stars, last pushed 2mo ago), licensed MIT. It adds 57 tokens to every session and 1,551 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to handoff, differing in 2 lines, and is treated as a copy.
