Skills
Git Output Compaction
Rewrites git status, diff and log output into compact summaries grouped by state, keeping hash, author and subject only.
Test Failure Filtering
Filters cargo test, npm test, pytest and go test output down to failures, collapsing passing tests into a single count.
Agent Hook Setup
Installs a hook with rtk init that rewrites an agent's shell commands to rtk equivalents in Claude Code, Cursor, Codex and more.
Output Analytics
Reports how much command output was filtered with rtk gain, as summaries, daily breakdowns, ASCII graphs or JSON exports.
API Traffic Proxy
Runs the optional rtk-proxy daemon, which compresses an agent's provider-API payloads before forwarding them to the model provider.
