dsh-plugins (gen-limit)

dsh-plugins

Plugins for DeepSeek Harness. One repo, eight packages, published independently under @creait. They came out of running dsh against self-hosted models, and each closes a gap the harness leaves open.

Package	What it does	Why
hookkit @creait/dsh-hookkit	Config-driven lifecycle hooks, including context injection. Declare event → handler → outcome in YAML.	dsh has the seams (agent/pre-step, tools/pre-execute, …) but reaching them means writing a plugin. This turns them into config.
gen-limit @creait/dsh-gen-limit	Per provider/model concurrency cap, enforced at subagent spawn and at the stream, with a settings card.	One self-hosted GPU has a real ceiling; a fan-out of subagents will find it. Denying the spawn beats letting the child die opaquely.
web-search-searxng @creait/dsh-web-search-searxng	Points web_search at a self-hosted SearXNG instance instead of the native route.	Search without handing every query to a third party.
web-fetch @creait/dsh-web-fetch	A guarded local fetch provider behind ctx.web, with SSRF blocking on the resolved address.	dsh implements web_fetch in full but ships no provider, so the tool is present and every call fails.
research-mode @creait/dsh-research-mode	Deep research as an agent mode: a fixed, reviewed loop that plans, researches in adaptive parallel rounds, synthesises and reviews.	A loop the model rewrites per call re-earns the same mistakes per call. Shipping it as a preset also keeps it out of every session that is not research.
think-level @creait/dsh-think-level	A reasoning effort per provider and model, plus one control to change it for the session you are in.	dsh's effort dropdown is per session and remembered nowhere, so "this model should think hard" is re-typed in every new conversation. Subagents are never asked at all.
tool-disclosure @creait/dsh-tool-disclosure	Progressive tool disclosure: a deferred group of tools costs one catalog line until the model loads it with tool_search.	dsh advertises every mounted tool on every request. An MCP server's 24 browser schemas are ~4.4k tokens charged to every session, including the ones that never open a browser.
to-english @creait/dsh-to-english	Rewrites a market-installed plugin's Chinese copy into English with a model you already have configured, guarding the Chinese the program itself reads.	Most of the market is written in Chinese, and a blunt find-and-replace gives you a plugin that reads English and no longer works.

hookkit is the general-purpose one: a small engine that ships no hooks of its own — 13 lifecycle events × 3 handler kinds (in-process tool, shell, HTTP) × 3 outcomes (inject context, deny the call, fire-and-forget). It is what makes something like memory recall a config change rather than a plugin. The rest are single-purpose. web-search-searxng and web-fetch are both providers for the same ctx.web seam and compose: together they give an agent search and page reading without a third-party round trip. research-mode wants web-fetch mounted — without it, its researchers are capped at search snippets. to-english is the outlier: it acts on the other plugins you install rather than on a harness seam.

Install

Each package installs on its own — you do not need the others:

dsh plugin --profile web add @creait/dsh-hookkit

Every package ships its own bundle patch, so that command mounts the row rather than only recording the dependency. Mounting is not the same as switching on: the two ctx.web providers register themselves and then wait to be pointed at something, and hookkit mounts with no hooks declared. Each README says which keys finish the job.

Develop

The packages resolve their dsh peer dependencies from the harness you have installed, not from the registry, so you are always building against the version you actually run:

DSH="$(npm root -g)/@deepseek-ai/dsh/node_modules/@deepseek-ai"
mkdir -p node_modules/@deepseek-ai
for p in cordis dsh-llm dsh-settings dsh-web schemastery; do
  ln -sfn "$DSH/$p" "node_modules/@deepseek-ai/$p"
done

Then:

pnpm test        # 577 tests across the eight packages

Do not run pnpm install at the root — it would replace those symlinks with published copies that may not match your harness.

To run a checkout against a live harness, link the package directory into a profile:

// ~/.dsh/profiles/web/package.json
"dependencies": {
  "@creait/dsh-hookkit": "link:/path/to/dsh-plugins/hookkit"
}

then pnpm install in the profile and restart dsh web. The boot manifest is built at startup, so adding a plugin needs the restart — editing a linked one does not.

Release

Versions are independent; publish only what changed:

cd hookkit && npm publish --access public

pnpm publish-all does every package that has a new version. Scoped packages default to restricted, so --access public matters on a package's first publish.

Caveat

All eight bind to pre-1.0 internal dsh seams with no compatibility guarantee. peerDependencies pins the versions each was built against; a harness upgrade can move them. Each README has a "What breaks this" section.
