Token Savings

Compress noisy command output at the source, so agents spend context on signal instead of terminal spam.

How Boost saves tokens

A verbose test log floods the context. Boost keeps the failure, the summary, and the next clue, and drops the rest.

Boost is on. Toggle it off to see the raw, context-flooding output it just hid.


What Boost keeps

Boost preserves the signal: failures, summaries, counts, and next clues. The repetitive stream gets compressed before it spends context.

Where it helps most

The noisiest commands your agent runs (tests, builds, and logs) shrink the most.

boost — noisy commands
# noisy test runs
pytest -q
go test ./...
npm test

# build & lint logs
npm run build
npx tsc --noEmit
ruff check .

# diffs, logs & debug output
git diff
docker logs app
kubectl logs deploy/api

Measure what you saved

Boost tracks raw versus filtered size and estimates saved tokens per command. Run boost report for aggregate savings, or add a TOML filter for custom tools.


# sustainability

Emission Savings

Every saved token is energy you didn't burn. Boost translates raw token savings into an estimated emissions impact, so the work your agents skip becomes a number you can share with your team.

boost — emissions
$ boost report

Saved 1.7M tokens of terminal noise.

You avoided 359 g CO2e. ≈ 0.21 kg CO2e / 1M saved tokens.

Less noise → less compute → less AI exhaust in the atmosphere.

emissions estimated CO2e avoided

The estimate uses a configurable kg-CO2e-per-million-saved-tokens heuristic. It's a directional sustainability signal, not audited carbon accounting, but it turns context saved into a concrete reminder that less AI exhaust reaches the atmosphere.
