Cf Handoff

CLI Usage: When unsure about a CLI's interface or flags, run it with --help first. Do NOT attempt to discover functionality by reading plugin source code — doing so leads to incorrect execution from assumptions made without context of the holistic flow.

Session Handoff

Generate or preview the session handoff document for the current CLEAR session. Captures metrics, decisions, progress, and priorities for the next session.

Plugin Root Resolution

CLI commands in this skill reference $CLEAR_PLUGIN_ROOT — a .claude/settings.json env var the shell expands. The SessionStart hook persists it, but settings env vars load at session launch, so on a brand-new consumer's first session (before its next restart) the variable is empty and node "$CLEAR_PLUGIN_ROOT/build/..." fails with MODULE_NOT_FOUND.

First-session bootstrap — if $CLEAR_PLUGIN_ROOT is empty, set it inline in the same Bash call as the CLI (each Bash call is a fresh shell, so a separate export would not carry over):

export CLEAR_PLUGIN_ROOT="${CLEAR_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}"

Prepend it to the CLI in one shell line: export CLEAR_PLUGIN_ROOT="${CLEAR_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}"; <node "$CLEAR_PLUGIN_ROOT/build/..." command>. ${CLAUDE_PLUGIN_ROOT} resolves in this SKILL.md body to the actually-loaded plugin path; once the consumer restarts, $CLEAR_PLUGIN_ROOT is populated and the assignment is a harmless no-op.

When to Use This Skill

DO NOT use for:

• Initializing a new session (use /cf-init instead)
• Viewing session status without generating a handoff (use /cf-status instead)

Usage

• /cf-handoff -- Generate the handoff document
• /cf-handoff --preview -- Preview contents without creating a file

Instructions

Step 0: Pre-flight Check

if [ -f ".clear/state/session.json" ]; then echo "SESSION_ACTIVE"; else echo "NO_SESSION"; fi

If NO_SESSION: display "No active CLEAR session. Run /cf-init to initialize CLEAR." and stop.

Branch: --preview

If $ARGUMENTS contains --preview, read session state and display a preview:

SESSION_STATE=$(cat .clear/state/session.json)
SESSION_NUM=$(echo "$SESSION_STATE" | jq -r '.clearSessionNumber')
TOKEN_PCT=$(echo "$SESSION_STATE" | jq -r '(.tokenUsage.estimate * 100) | floor')
CONVERSATION_TURNS=$(echo "$SESSION_STATE" | jq -r '.tokenUsage.promptCount')
echo "Handoff Preview for Session ${SESSION_NUM}"
echo "========================================"
echo "Token Usage: ${TOKEN_PCT}% | Conversation Turns: ${CONVERSATION_TURNS}"
echo ""
echo "The handoff document will include:"
echo "- YAML frontmatter with all metrics (to be updated)"
echo "- Summary, Completed/In Progress items, Technical decisions"
echo "- Patterns Established, Learnings, Patterns Observed"
echo "- Changes this session (knowledge, plan, workpackage)"
echo "- Code changes table, Test results, Next session priorities"
echo ""
echo "Run /cf-handoff without --preview to generate the document."

Stop after displaying preview.

Branch: Generate (no --preview)

Step 1 -- Generate: Invoke session-handoff.sh. The $CLEAR_PLUGIN_ROOT bootstrap is prepended in the same shell line (per Plugin Root Resolution above) so this works on a brand-new consumer's first session, before the settings env var has loaded:

export CLEAR_PLUGIN_ROOT="${CLEAR_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}"; \
  echo '{"session_id": "manual", "cwd": "'"$(pwd)"'", "manual": true}' | \
  "$CLEAR_PLUGIN_ROOT/scripts/session/session-handoff.sh"

Step 2 -- Display result. The script returns JSON with the document path. Show:

Handoff document generated at: .clear/sessions/session_N_YYYYMMDD.md

Next steps:
1. Update YAML frontmatter metrics (prod/test files, lines, test results, complexity, hours)
2. Fill in markdown sections (Summary, Completed Items, Technical Decisions, Patterns Established, Learnings, Patterns Observed, Code Changes, Next Priorities)
3. Change status from PARTIAL to COMPLETE when done

Step 3 -- Open for editing. Read the generated file so Claude can help fill it in:

HANDOFF_PATH=$(cat .clear/state/session.json | jq -r '.handoff.documentPath')
cat "$HANDOFF_PATH"

YAML Frontmatter Reference

The handoff uses a single YAML frontmatter block. Key fields:

Retrospective Sections

The handoff scaffolds four retrospective sections: ## Technical Decisions, ## Patterns Established, ## Learnings, ## Patterns Observed.

If you captured a technical decision, pattern, or learning via /cf-knowledge during the session, include its knowledge ID (e.g., TD-N, PAT-N, LES-N) in the handoff entry. Items without IDs document content in the handoff but are not registered as knowledge entries. ## Patterns Observed is for in-session observations that aren't yet established patterns (no associated knowledge ID).

Bullet format inside each section is open — fill conversationally. Leave a section's bullets empty if nothing applies.

Auto-trigger Note

The underlying script (scripts/session/session-handoff.sh) is invoked automatically by session-monitor.sh at the critical threshold (75% by default — configurable via .clear/config/session-management.yaml). This skill is the manual invocation surface for the same script — both paths produce the same handoff document. Auto-generated documents will have placeholder values that should be updated before finalizing.

After Handoff

1. Finalize the handoff document — edit .clear/sessions/session_N_<date>.md directly via Edit (the path-allowlist carve-out permits this). Update placeholder zeros and status: PARTIAL → status: COMPLETE once the session is closed out.
2. Commit the handoff document to version control.
3. The next session can resume using the documented priorities.

Metrics capture runs automatically at the start of the next session (session-init.sh scans .clear/sessions/ for finalized handoffs and appends to .clear/metrics/metrics.csv). Only handoffs whose status: value contains complete (any case — COMPLETE, Complete, completed, etc.) are captured; partial/abandoned handoffs are ignored. One-session lag is intentional; no manual invocation required.

Completion Checklist

• Session state verified as active
• Handoff document generated (or preview displayed)
• Handoff file opened for review and editing
