handoffCompact the current conversation into a handoff document for another agent to pick up.
Handoff is an agent skill from alirezarezvani/claude-skills. Compact the current conversation into a handoff document for another agent to pick up. Save to a user-configured location (OS temp, home folder, or per-project .handoff/), redact secrets before write, suggest skills for the next session, and auto-load the latest handoff on the next SessionStart. First-run setup asks where to save so the project folder never gets cluttered. Use when the user says 'hand this off', 'handoff doc', 'summarize this for a new session', 'compact this conversation', 'I'm ending this…
Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 17 other files, including scripts, reference files and assets (for example `README.md`, `assets/example_handoff.md` and `references/configuration.md`).
It sits in Agent Workflows. The repository describes itself as: 380 Claude Code skills & agent skills & plugins (30+ Agents, 70+ custom commands, 380+ skills, customizable references, scripts)for Claude Code, Codex, Gemini CLI, Cursor, and 8… The licence is MIT.
Read from SKILL.md and the folder at commit 19392f7. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 7 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3From the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
github.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Handoff loads about 2.5k tokens when it runs, and up to ~8.4k if it reads all its reference files. Until then it costs about 196 tokens; SKILL.md has 1,100 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- `.env`-style `KEY=value` lines containing secretsAutomated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

.claude/skills/handoff/SKILL.md (or your agent's skills folder). This skill also uses 14 other files; get the full folder from GitHub.Write a handoff document summarising the current conversation so a fresh agent can continue the work. Save to the temporary directory of the user's OS — not the current workspace.
Include a "suggested skills" section in the document, which suggests skills that the agent should invoke.
Do not duplicate content already captured in other artifacts (PRDs, plans, ADRs, issues, commits, diffs). Reference them by path or URL instead.
Redact any sensitive information, such as API keys, passwords, or personally identifiable information.
If the user passed arguments, treat them as a description of what the next session will focus on and tailor the doc accordingly.
Explicit phrases (any of):
Implicit signals (no phrase, but the intent is unmistakable):
When you detect an implicit trigger, propose the handoff before running it: "Want me to write a handoff for the next session?" — never run it silently.
On first invocation, the skill asks where to save handoffs so the project folder never gets cluttered. Setup is offered once via "Run setup now? (Y/n)" — answering N uses OS-temp defaults for this run and never re-prompts. The user can rerun setup any time via /cs:handoff-setup.
See references/configuration.md for the full config field reference.
The save location is read from the user's config (~/.config/handoff/config.json, or the project-local .handoff/config.json if present). When no config exists and the user declined setup, fall back to:
mktemp -t handoff-XXXXXX.mdRead the file before you write to it.
The handoff doc has five sections. Use these exact headers:
See references/handoff_structure.md for a worked example.
Filling in the five sections is the agent's job, not the script's. Follow references/handoff_prompt.md as a mandatory checklist:
For each topic discussed in the conversation, decide explicitly: include in State of play / log as an Open decision / drop with reason.
Free-handing the summary leads to rosy progress reports and dropped blockers. The checklist prevents that.
Matt's no-duplication discipline made concrete:
See references/deduplication_discipline.md for the full list.
Before saving, the linter scans the draft for secrets and PII. In strict mode (default) it blocks save on findings; in warn mode it flags inline and saves anyway.
Redact:
-----BEGIN ... PRIVATE KEY----- blocks.env-style KEY=value lines containing secretsSee references/redaction_checklist.md for the full pattern list and manual-review steps for what regex cannot catch.
When the plugin is installed, a SessionStart hook scans the configured save location for the most recent handoff (within the retention window) and surfaces it to the new session as <handoff_from_previous_session> data. The next agent reads it as context, not as instructions — suggested actions must be verified against current state before executing.
Disable per-session with HANDOFF_SESSIONSTART=0.
A paired SessionEnd hook checks whether a recent handoff exists when the session is ending. If none does (or the most recent is older than 30 minutes), it prints a one-line reminder so the user is prompted to write one before context is lost.
The hook cannot prompt interactively or block session end — it surfaces text in the session log.
Disable per-session with HANDOFF_SESSIONEND=0.
When work continues past the original handoff time, refresh in place instead of creating a new file:
python3 scripts/handoff_template_generator.py --refresh --goal "<updated goal>"Prints the path of the most recent handoff. The agent edits it directly. Keeps the save location uncluttered and ensures the SessionStart hook always loads the up-to-date version.
| Tool | Purpose |
|---|---|
setup.py | First-run Q&A — save location, retention, redaction strictness, git-context, recommender scope. |
handoff_template_generator.py | Writes the 5-section scaffold at the configured path. --refresh reuses the most recent handoff instead of creating a new file. |
redaction_linter.py | Scans the draft for secrets/PII before save. Exit 1 on findings in strict mode. |
handoff_self_check.py | Fidelity check — flags empty Goal, State bullets without artifacts, missing Decisions when git is dirty, too few/many Skills, inline content in Artifacts. Run before the linter. |
skill_recommender.py | Suggests 3-5 skills for the next session based on goal text + repo scan. |
cleanup.py | Deletes scaffolds older than the retention window. mtime-guarded — never deletes a handoff the user edited. |
config_loader.py | Shared helper: read project config → global config → defaults. |
/cs:handoff [optional next-session description] — generate the handoff./cs:handoff-setup — reconfigure save location, retention, redaction.cs-handoff-author — Matt-voice persona orchestrating the skill. Terse, no-duplication, references-not-copies.
User: /cs:handoff "finish wiring the redaction linter and open a draft PR"The skill walks the mandatory checklist, generates a 5-section scaffold, fills it from the conversation, runs the redaction linter, and saves to the configured location. See assets/example_handoff.md for a complete worked example.
User: I'm packing up for the day, let me come back to this tomorrow.Detect the implicit signal. Propose before running: "Want me to write a handoff for the next session?" — never silently. On confirmation, proceed as Example 1 with an inferred goal.
User: /cs:handoff "ship the migration"
Skill: Run setup now? (Y/n)
User: Y
[setup walks 5 questions: save location, retention, redaction strictness, git context, recommender scope]
Skill: Config saved to ~/.config/handoff/config.json. Continuing with handoff for: ship the migration.If the user answers N, the skill writes a sentinel and uses defaults (OS temp dir, 7-day retention, strict redaction). The prompt never re-appears.
On the next session, the SessionStart hook scans the configured save location, finds the most recent handoff, and surfaces it as <handoff_from_previous_session> data. The next agent reads it as context, not instructions.
| Step | Command |
|---|---|
| First-run setup | /cs:handoff-setup (or answer Y on first /cs:handoff) |
| Generate a handoff | /cs:handoff [goal] |
| Reconfigure later | /cs:handoff-setup --reconfigure |
| Project-specific config | /cs:handoff-setup --project |
| Disable SessionStart hook | HANDOFF_SESSIONSTART=0 (per session) |

Compact the current conversation into a handoff document for another agent to pick up. Handoff is an agent skill from alirezarezvani/claude-skills. Compact the current conversation into a handoff document for another agent to pick up.
Handoff fits situations like: the user says hand this off; summarize this for a new session; compact this conversation; im ending this session.
Run `npx skills add alirezarezvani/claude-skills --skill handoff -a claude-code`. Or copy the skill folder (productivity/handoff/skills/handoff in alirezarezvani/claude-skills) into .claude/skills/handoff in your project. Claude Code loads it when a task matches its description.
Run `npx skills add alirezarezvani/claude-skills --skill handoff -a codex`. Or copy the skill folder (productivity/handoff/skills/handoff in alirezarezvani/claude-skills) into .agents/skills/handoff in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add alirezarezvani/claude-skills --skill handoff -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/handoff, .gemini/skills/handoff, .github/skills/handoff and .opencode/skills/handoff in your project.
Going by SKILL.md and its folder, Handoff needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3.
SKILL.md names 1 domain. As links in the text: github.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Handoff is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.5k tokens (SKILL.md is roughly 9.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 5.9k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Handoff: MCP Server Builder (anthropics/skills, 180k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 38k stars), Using Superpowers (farm-fe/farm, 5.6k stars) and Executing Plans Inline (obra/superpowers, 297k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
