## Stats (pre-injected)
Display comprehensive project statistics including phases, plans, requirements, git metrics, and timeline.
Read all files referenced by the invoking prompt's execution_context before starting.
Gather project statistics:
```bash
STATS=$(pi-gsd-tools stats json)
if [[ "$STATS" == @file:* ]]; then STATS=$(cat "${STATS#@file:}"); fi
```
Extract fields from JSON: `milestone_version`, `milestone_name`, `phases`, `phases_completed`, `phases_total`, `total_plans`, `total_summaries`, `percent`, `plan_percent`, `requirements_total`, `requirements_complete`, `git_commits`, `git_first_commit_date`, `last_activity`.
Present to the user with this format:
```
