Manual Session Handoff

This skill captures everything the next session needs to resume work. It supplements /compact -- /compact summarizes the conversation lossily; this writes durable, structured state.

Resolve paths first

• Memory dir -- the memory/ sibling next to the current session's transcript. The Claude Code path is ~/.claude/projects/{encoded-cwd}/memory/. Use ~ (the user's home dir); never assume a specific username. {encoded-cwd} is the working directory with /, :, and \ replaced by -.
• Vault root -- read $OBSIDIAN_VAULT_PATH. If unset, skip the vault mirror step and tell the user once at the end.
• Active project slug -- read $ACTIVE_PROJECT if set; otherwise scan ${OBSIDIAN_VAULT_PATH}/10_Projects/*/overview.md for status: active and pick the first match. If none match, omit the active-project line.

How to execute

1. Build the handoff content yourself -- do NOT delegate this to a subagent. The current session has the context; a fresh agent would not.

2. Collect the following from the conversation + live tools:

   • Current focus -- one paragraph: what are we working on right now?
   • Focus arg -- if the user passed $ARGUMENTS, lead with that
   • Recent decisions -- anything the user approved or steered (look for "yes", "do it that way", corrections)
   • Open questions -- unresolved items blocking progress
   • Files touched this session -- from your tool-call memory, list the last ~10 Read/Edit/Write paths
   • Active project state -- read ${OBSIDIAN_VAULT_PATH}/10_Projects/{active-slug}/overview.md frontmatter, the latest note in runs/, and ~/.claude/projects/{encoded-cwd}/memory/MEMORY.md if relevant
   • In-progress TODOs -- from the current TodoWrite list
   • Next step -- one sentence: what should the next session do first?

3. Write two files using the Write tool:

   Primary: ~/.claude/projects/{encoded-cwd}/memory/handoff_latest.md Vault mirror (only if $OBSIDIAN_VAULT_PATH is set): ${OBSIDIAN_VAULT_PATH}/00_Inbox/handoff-{YYYY-MM-DD}.md

   Frontmatter schema:

   ---
   name: handoff-YYYY-MM-DD-HHMM
   type: handoff
   created: YYYY-MM-DD HH:MM:SS
   trigger: manual
   focus: "$ARGUMENTS"
   ---
   

4. Archive the prior handoff first: if ~/.claude/projects/{encoded-cwd}/memory/handoff_latest.md exists, copy it to ~/.claude/projects/{encoded-cwd}/memory/handoffs/{its-created-timestamp}.md before overwriting. Use Bash cp (POSIX) or Copy-Item (Windows) for this.

5. Commit the vault (only if the user's vault is a git repo and a vault root was resolved):

   git -C "$OBSIDIAN_VAULT_PATH" add 00_Inbox/ && \
     git -C "$OBSIDIAN_VAULT_PATH" commit -m "handoff: YYYY-MM-DD"
   

   Skip silently if the vault isn't under git or the commit returns non-zero.

Report to the user

One short line: "Handoff written: handoff_latest.md + vault mirror. Focus: $ARGUMENTS. Next session will see it on start."

If the vault mirror was skipped (no $OBSIDIAN_VAULT_PATH), say so in the same line.

Do not dump the full handoff content back into chat -- that defeats the purpose.

Handoff note template

# Handoff -- {timestamp}

**Focus:** {$ARGUMENTS or "general session state"}
**Active project:** {slug -- status=, latest run=}
**CWD:** {current working dir}

## Current focus
{one paragraph}

## Recent decisions this session
- {bullet}
- {bullet}

## Open questions / blockers
- {bullet}

## Files touched
- `path/to/file.py`
- `...`

## In-progress TODOs
- [in_progress] {content}
- [pending] {content}

## Next session should
{one imperative sentence}

## Related vault notes
- [[10_Projects/{active-slug}/overview]]
- [[30_Literature/{citekey}]]

Notes

• If the user types /handoff with no args, still write the handoff -- use "general session state" as focus.
• The PreCompact hook (at ~/.claude/hooks/precompact-handoff.py) writes a lighter version automatically on /compact. /handoff is for when the user wants a richer, human-curated snapshot.
• Never delete history in ~/.claude/projects/{encoded-cwd}/memory/handoffs/ -- it's cheap and sometimes rescuing.
