handoff

/handoff

End-of-session debrief. Three artifacts each pass:

1. Granular MCP captures — one per decision/lesson/gotcha (DB authoritative).
2. Session log md — narrative thread at ~/.wenlan/sessions/<YYYY-MM-DD-HHmm>-<slug>.md.
3. Project status md + json — current goals + last-handoff timestamp at ~/.wenlan/sessions/_status/.

These are orthogonal: captures are queryable atoms, session log is the narrative thread, status file lets the next session see where we left off.

Steps

1. Detect project + last handoff time

Bash: cd_repo=$(git -C "$PWD" rev-parse --show-toplevel 2>/dev/null); echo "${cd_repo:-no-git}"

• If output is a path → use the basename as <project> (e.g. wenlan).
• If no-git → use the cwd basename. Skip git steps below; rely entirely

on conversation context.

Read ~/.wenlan/sessions/_status/handoff-<project>.json for lastHandoff timestamp (ISO-8601). If file missing, default to "12 hours ago".

1.5 Pending-captures preview

After establishing <lastHandoff>, call:

list_pending(limit=50)

The MCP returns memory rows with source_id, content, created_at, and other metadata. Convert lastHandoff (ISO-8601 string, e.g. 2026-05-13T22:50:00Z) to a Unix epoch seconds integer before filtering:

Bash: date -j -f %Y-%m-%dT%H:%M:%SZ "$lastHandoff" +%s

Or in your scripting language of choice (Python's datetime.fromisoformat, JavaScript's Date.parse, etc.). Save the result as lastHandoffEpoch.

Then filter the response rows: keep where row.created_at >= lastHandoffEpoch. These are captures this session produced that the quality gate left unconfirmed (untrusted-source captures).

If the filtered list is empty, say nothing. Proceed to Step 2.

If non-empty, render a preview block once, before the existing capture flow:

Pending captures this session (<N> total, top 3 shown):

1. mem_xyz789  "..."  (untrusted source: <agent>)
2. ...

Default: proceed (captures stay pending). Opt in by running
`/curate captures` before re-invoking /handoff if you want to walk them.

Do NOT prompt for per-item action inline. The user proceeds with /handoff regardless; the preview is informational only.

2. Gather session context (parallel, only if git repo)

Bash: git -C <repo> log --oneline --since=<lastHandoff>
Bash: git -C <repo> status --short
Bash: git -C <repo> diff --stat HEAD~5..HEAD 2>/dev/null
Bash: git -C <repo> worktree list

Capture output. Use it alongside conversation history to infer what happened. If not a git repo, skip — conversation context is the source.

3. Infer, do not ask

Synthesize silently from git output + conversation. Categorize each item into user-facing groups. Each maps to a daemon memory_type for the capture call:

| Display label | daemon memory_type | What belongs here | |---|---|---| | Decisions | decision | architectural choice, tool/pattern selection (with WHY) | | Lessons | lesson | root cause discovered, workaround found, technical insight | | Insights | gotcha | unexpected behavior, debugging discovery, sharp edge | | Corrections | preference | user pushed back, corrected approach or assumption | | Facts | fact | durable project/people/tool fact worth persisting |

Non-memory items (not stored, session-log only):

• Open threads — started but not finished, blockers.

Skip purely mechanical facts already in git (file paths, function names, config values). The commit log preserves those.

Resolve the active space (once per /handoff invocation)

Call the bundled resolver once at the top of the handoff, before any captures:

resolved="$("$CLAUDE_PLUGIN_ROOT/bin/resolve-space.sh" --cwd "$PWD" 2>/dev/null)" space="$(printf '%s\n' "$resolved" | cut -f1)" source_layer="$(printf '%s\n' "$resolved" | cut -f2)"

if [ -n "$space" ]; then echo "Resolved space: $space (from $source_layer)" else echo "Resolved space: none (unscoped)" fi

Pass space="$space" to every capture(...) call in the loop only when space is non-empty. /handoff does not accept a space:X inline arg — if the user wants a different space, they set WENLAN_SPACE before invoking.

4. MCP captures (one per item)

For each non-trivial item, call with the mapped memory_type:

capture(content="<one self-contained sentence with WHY>", memory_type="<decision|lesson|gotcha|preference|fact>", space=<resolved if non-empty>)

Atomic: one decision per call. Don't merge multiple items into one memory. The daemon dedups against existing knowledge, so re-storing known facts is a no-op.

Only surface items to the user BEFORE storing if they meet one of these bars:

• Contradicts an existing memory (recall returned a conflicting fact).
• Marks a critical incident, irreversible action, or production change.
• You are uncertain whether the item is durable vs transient.

Otherwise just store and report counts at the end.

5. Write session log

Bash heredoc to ~/.wenlan/sessions/<YYYY-MM-DD-HHmm>-<slug>.md:

# Session <YYYY-MM-DD HH:MM> — <slug>

**Project:** <project>
**Range:** <lastHandoff> → <now>

## Accomplished
- <item>

## Decisions
- <decision and rationale>

## Lessons & Gotchas
- <root cause / workaround>

## Open Threads
- <what's unfinished>

## Captures stored
- <source_id_or_brief_summary>

## Git summary
<git log --oneline output>

<slug> = kebab-case 2-4 word summary (session-handoff-md-writer).

6. Update project status

Overwrite ~/.wenlan/sessions/_status/<project>.md:

# <Project> — Current Status

## Last session (<date>)
- <accomplished bullet>

## Active
<!-- Items touched/spawned in the last 1-2 sessions. Real next-move candidates. -->
- <item> (added <YYYY-MM-DD>)
- <blocked item> (added <YYYY-MM-DD>) (gated: <trigger>)

## Backlog
<!-- Older accretion. Not gated, not picked. Promote back to Active when re-engaged. -->
- <item> (added <YYYY-MM-DD>)

Single file per project. New session overwrites — this is the current state, not a log.

Two sections, not one flat list: ## Active and ## Backlog separate the two types of tasks that get mixed otherwise. Active = fresh signal worth picking next. Backlog = older parked items, kept for reference but not in the "what next?" frame.

Date stamp every bullet with (added <YYYY-MM-DD>). Use today's date when adding a new item; preserve the original date when carrying an item forward. Dates make age visible at a glance and avoid relative-time drift.

Gated items stay inline-tagged with (gated: <trigger>) — no separate section. The tag tells the reader why it can't move yet; the bullet stays in whichever section reflects its recency.

Promotion / demotion rules:

• New item this session → ## Active with today's date
• Item in ## Active that wasn't touched this session AND wasn't touched

the prior session → demote to ## Backlog (keep original date)

• Item in ## Backlog that work resumed on → promote back to ## Active

(keep original date — staleness is a property of the work, not the bullet text)

7. Write timestamp

Overwrite ~/.wenlan/sessions/_status/handoff-<project>.json:

{
  "lastHandoff": "<ISO-8601 now>",
  "project": "<project>",
  "summary": "<one-line>"
}

Per-project file prevents parallel sessions from clobbering each other.

8. Auto-commit ~/.wenlan/

After writing the files above, snapshot the change so the user can git log their memory's life timeline. Defensive — silent skip if git is missing or ~/.wenlan/ is not a repo yet.

Bash: git -C ~/.wenlan add -A && \
      git -C ~/.wenlan -c user.name=Wenlan -c user.email=daemon@wenlan.local \
          commit --quiet -m "session: <slug>" 2>/dev/null || \
      (sleep 1 && git -C ~/.wenlan add -A && \
       git -C ~/.wenlan -c user.name=Wenlan -c user.email=daemon@wenlan.local \
           commit --quiet -m "session: <slug>" 2>/dev/null) || true
