2 stars2 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Lightweight session initialization. Reads latest manifests and handoffs to resume context. Loads only what the current task needs. Trigger on session start, "resume", "pick up where I left off", "continue from last session", "init".

Session Init Skill

Initializes a session with minimal context. Checks for prior work to resume, cleans stale data, and reports readiness.

When to Activate

First message of a new session (if user wants to resume prior work)
User says "resume", "init", "pick up where I left off", "continue from last session"

Protocol

Step 1: Check for Active Handoffs

ls -lt _context/handoffs/*.md 2>/dev/null | head -3

If a handoff exists from the last 48 hours, read and summarize the most recent one in 2 sentences.

Step 2: Check for Active Manifests

# Today's manifests
ls .claude/manifests/$(date -u +%Y-%m-%d)/*.jsonl 2>/dev/null
# Yesterday's manifests
ls .claude/manifests/$(date -u -v-1d +%Y-%m-%d)/*.jsonl 2>/dev/null

If manifests exist from today or yesterday:

Count total entries across all files
Extract entries with type: "followup" or type: "error"
Summarize: N findings, N decisions, N follow-ups, N errors

Step 3: Clean Stale Data

# Archive manifest folders older than 7 days
find .claude/manifests/ -maxdepth 1 -type d -mtime +7 -not -name archive -not -name manifests 2>/dev/null | while read dir; do
  mv "$dir" .claude/manifests/archive/ 2>/dev/null
done

Step 4: Report

Present a brief session context (under 150 tokens):

Session ready.
- Handoff: {title} ({date}): {1-line summary}
- Manifests: {N} entries from {date}. Follow-ups: {list}
- Suggested next: {action from handoff or open follow-ups}

If nothing exists:

Clean session. No prior handoffs or manifests.

Rules

NEVER load other skills proactively. Skills load on demand by trigger.
Keep init output under 150 tokens. The point is to stay lean.
If user explicitly states what they want to work on, skip resume checks and go straight to their task.
Do NOT read MEMORY.md here; it is auto-loaded by Claude Code already.
