Rewriting Git Commits Skill

You coordinate three parallel agents (analyst, narrator, and scribe) to rewrite git commit sequences into clean, logical commits.

Input

The changeset description: $PROMPT

Your Task

Step 1: Establish Session ID

Create a unique session ID for the agents to communicate via sidechat:

# Generate timestamp-based session ID
TIMESTAMP=$(date +%Y%m%d-%H%M%S)
SESSION_ID="historian-$TIMESTAMP"

# Create work directory for storing state and logs
WORK_DIR="/tmp/$SESSION_ID"
mkdir -p "$WORK_DIR"

# Initialize state file
CURRENT_BRANCH=$(git rev-parse --abbrev-ref HEAD)
cat > "$WORK_DIR/state.json" <<EOF
{
  "session_id": "$SESSION_ID",
  "timestamp": "$TIMESTAMP",
  "original_branch": "$CURRENT_BRANCH",
  "work_dir": "$WORK_DIR"
}
EOF

echo "Created session: $SESSION_ID"
echo "Work directory: $WORK_DIR"

Save both $SESSION_ID and $WORK_DIR for later use.

Step 2: Launch All Three Agents in Parallel

CRITICAL: Make THREE Task calls in a SINGLE message to launch all agents in parallel:

Task(
  subagent_type: "historian:analyst",
  description: "Analyze changeset and create commit plan",
  prompt: "Session ID: $SESSION_ID
Work directory: $WORK_DIR
Changeset: $PROMPT"
)

Task(
  subagent_type: "historian:narrator",
  description: "Execute commit plan",
  prompt: "Session ID: $SESSION_ID
Work directory: $WORK_DIR"
)

Task(
  subagent_type: "historian:scribe",
  description: "Create commits with build validation",
  prompt: "Session ID: $SESSION_ID
Work directory: $WORK_DIR"
)

The agents coordinate via sidechat MCP. You will block here until all complete.

Step 3: Report Results

Read $WORK_DIR/state.json to extract original_branch, clean_branch, and commits_created. Report success with the branch names and commit count.
