# engram cost Show token-savings telemetry from engram's hook log. Three modes: 1. **Default** — terminal table for the current project: `engram cost` 2. **Multi-project** — across many roots: `engram cost -p /path/a -p /path/b` 3. **Weekly digest** — Markdown file at `~/.engram/cost-report-YYYY-Www.md`: `engram cost --digest` Run the requested mode and report the totals: - Tokens saved (numeric, with K/M suffix) - Reduction ratio (percentage) - Approximate USD saved (Claude Sonnet 4.6 input pricing by default) - Total events (number of intercepted tool calls) If the user passed "$ARGUMENTS", treat it as flag input (e.g., `--digest`, `-p /path`). If the table shows zeroes, explain that historic events don't carry the new tokens-saved fields — real numbers populate within ~24 hours of v3.3 install. ## Example invocations **User:** "How much has engram saved me this week?" **You:** Run `engram cost --digest`. Read the output. Quote the totals: tokens saved, reduction ratio, approx USD. Mention the digest file path so the user can paste it into Slack. **User:** "Show me my engram numbers across all projects" **You:** Multi-project mode. Run `engram cost -p ~/proj-a -p ~/proj-b -p ~/proj-c` (substitute with the user's actual paths if they list them, otherwise default to the current directory). **User:** "Is engram even doing anything?" **You:** Run `engram cost --json` and pipe to a sanity check. If `events > 0` but `tokensSaved == 0`, the user is on engramx older than
