Token Chart

Token chart

Generate token-usage charts from the database or from session files.

Modes

• default — daily stacked token-usage bars across the last N days
• provider-model — stacked usage grouped by provider + model for attribution by model family
• provider-model-cost — estimated cost grouped by provider + model using the pricing reference bundled with the script

Examples

Default chart:

bun /workspace/.pi/skills/token-chart/token-chart.ts

Provider + model chart:

bun /workspace/.pi/skills/token-chart/token-chart.ts --mode provider-model

Estimated provider + model cost chart:

bun /workspace/.pi/skills/token-chart/token-chart.ts --mode provider-model-cost

Post to the web chat via IPC:

bun /workspace/.pi/skills/token-chart/token-chart.ts --ipc

Post via IPC and allow a Pushover nudge:

bun /workspace/.pi/skills/token-chart/token-chart.ts --ipc --nudge

Data sources

• default source: token_usage rows in ${PICLAW_STORE}/messages.db
• --source sessions: read usage from session files under ${PICLAW_DATA}/sessions instead of SQLite
• --sessions-dir <dir>: override the session-file location explicitly

Use --source sessions when DB-backed token usage is unavailable or when you want to inspect raw session-file history directly.

Output behaviour

• --ipc writes an IPC message JSON file and, if needed, an SVG media file so piclaw posts the chart to the web timeline.
• without --ipc, the script writes markdown to stdout with an embedded SVG data URL plus summary text.
• --output-svg <path> writes the SVG to a file in either mode.

Notes

• Numbers are formatted with compact K / M labels.
• Use this on demand unless you intentionally wire it into a scheduled task.
