Ralph Stats

Show historical Ralph loop session data from ~/.claude/ralph-wiggum-pro/logs/sessions.jsonl.

Parse Arguments

The user may provide arguments. Parse them:

--last N or -n N: Show last N sessions (default: 10)
--project NAME or -p NAME: Filter by project name (partial match)
--outcome TYPE or -o TYPE: Filter by outcome (success, max_iterations, cancelled, error)
--active or -a: Show only active (running) loops
--all: Show all sessions (overrides --last)

Execute Query

LOG_FILE="$HOME/.claude/ralph-wiggum-pro/logs/sessions.jsonl"

if [[ ! -f "$LOG_FILE" ]]; then
  echo "NO_LOG_FILE"
  exit 0
fi

if [[ ! -s "$LOG_FILE" ]]; then
  echo "EMPTY_LOG_FILE"
  exit 0
fi

# Output raw JSONL for parsing
echo "LOG_DATA_START"
cat "$LOG_FILE"
echo ""
echo "LOG_DATA_END"

Format and Display Results

Based on the output above:

If NO_LOG_FILE or EMPTY_LOG_FILE

Say: "No Ralph loop history found. Run some loops first!"

If LOG_DATA found

Parse the JSONL data between LOG_DATA_START and LOG_DATA_END. Each line is a JSON object.

Important: The log now uses a two-entry format:

Start entries have status: "active" with fields: session_id, project, project_name, state_file_path, task, started_at, max_iterations, completion_promise
Completion entries have status: "completed" with fields: session_id, outcome, ended_at, duration_seconds, iterations, error_reason

Merging logic:

Group all entries by loop_id (unique per loop invocation)
For each session:
- Find the start entry (status: "active") to get project, task, started_at, max_iterations, completion_promise
- Find the completion entry (status: "completed") to get outcome, ended_at, duration_seconds, iterations
- If only start entry exists (no completion), the session is currently active
- Merge fields from both entries into a unified session object

Handling active sessions:

Sessions with only a start entry (no completion entry) are currently running
Show them with status 🔄 active instead of an outcome
Calculate duration from started_at to now
Show iterations as ? (unknown until completion)

Apply any filters the user requested:

If --active specified, show ONLY sessions that have no completion entry (still running)
If --project specified, filter entries where project_name contains the value (case-insensitive)
If --outcome specified, filter completed entries where outcome equals the value
If --all NOT specified, limit to the last N entries (default 10)

Sort by started_at descending (most recent first), with active sessions at the top.

Important: The log now includes checklist data. Each session entry may include:

has_checklist: boolean - whether a checklist exists for this loop
checklist_progress: string or null - format "X/Y tasks • A/B criteria"

When merging entries, include these fields from the start entry.

Formatting rules:

Project: First 15 chars, truncated with ... if longer
Task: First 22 chars, truncated with ... if longer (reduced to make room for Checklist column)
Iters/Max: Show as X/Y where Y is max_iterations, or X/∞ if max_iterations is 0 (unlimited); for active loops show ?/Y
Checklist: Show checklist_progress value (first 18 chars), or - if null/empty
- Format is typically "X/Y tasks • A/B criteria" but may be truncated
- Only show if has_checklist is true, otherwise show -
Duration: (removed from table to make room for Checklist - can be shown in detailed view if needed)
Promise: Show completion_promise value (first 12 chars), or - if null/empty
Status with emoji:
- Active (no completion) → 🔄 active
- success → ✅ success
- max_iterations → ⏹ max
- cancelled → 🚫 cancel
- error → ❌ error
Started: Format started_at as YYYY-MM-DD HH:MM in local time

Summary line: Count total sessions and breakdown by status type (including active count).

If no sessions match filters

Say: "No sessions found matching your filters."

LOG LOCATION:
  ~/.claude/ralph-wiggum-pro/logs/sessions.jsonl

NOTE:
  The log uses a two-entry format:
  - Start entry: logged when loop begins (status: "active")
  - Completion entry: logged when loop ends (status: "completed")
  Sessions with only a start entry are currently running.
