What it is

Fast is a DeepSeek Harness plugin in the tools group, published to npm as `dsh-fast`. Read-only performance diagnostics for DeepSeek Harness: session load/restore timing, spill-hit counts, compaction count and trigger, context-injection volume (AGENTS.md/skills/tool-schema token share), and LLM cache hit rate — surfaced via /fast.

Version 0.2.20, licensed Apache-2.0, Node ^22.19.0 || >=24.0.0, DSH >=0.1.2-rc.1 <0.2.0 || >=0.1.5-alpha.1 <0.2.0 || >=0.1.6-0 <0.2.0 || >=0.1.7-0 <0.2.0 || >=0.2.0-rc.1 <0.3.0-0.

The repository is available as a local checkout, so the version and licence above are read from the package manifest that is actually published rather than from a registry copy.

Other plugins in the same group: Budget, Click, Data Quality, DoubleCheck, Draw, LSP Actions.

Install

Install through the dsh plugin command; the two shells differ only in how the second line confirms the result.

bash / sh

dsh plugin --profile default add dsh-fast
dsh --profile default --dump-config | grep 'dsh-fast'

PowerShell

dsh plugin --profile default add dsh-fast
dsh --profile default --dump-config | Select-String 'dsh-fast'

Substitute your own profile name for default, then restart the session — installation alone does not hot-load the plugin.
