dsh-minimal-anchor

A DeepSeek Harness (dsh) plugin that shields turn 1 from tool-schema overload.

Why

A fresh dsh session hands the model the entire configured toolset — file edits, bash, subagents, jobs — on message one, even when the first message is just "look at this repo and tell me what's going on." A smaller, focused schema on that first turn keeps the model's early reasoning on exploration instead of premature action, without touching how any later turn behaves.

dsh-minimal-anchor hooks the harness's own prompt-assembly pipeline to:

1. Prune tools on turn 1 only — down to a configurable whitelist (default: read, glob, grep).
2. Prepend a short structural preamble on that same turn, framing the session as exploration-first.
3. Get out of the way from turn 2 onward — every later assembly for that session passes through completely untouched, full toolset restored.

Install

dsh plugin --profile <name> add dsh-minimal-anchor

or from a local checkout:

dsh plugin --profile <name> add /path/to/dsh-minimal-anchor

This adds the package as a dependency of the profile, but does not by itself activate it — dsh only applies a package's dsh.bundle patch for packages listed in that profile's dsh.profile.bundles. Add the package name to that list in profiles/<name>/package.json:

{
  "dsh": {
    "profile": {
      "bundles": [
        "@deepseek-ai/dsh-base",
        "@deepseek-ai/dsh-headless",
        "dsh-minimal-anchor"
      ]
    }
  }
}

Confirm it composed with dsh --profile <name> --dump-config — you should see a minimal-anchor entry. (An equivalent alternative that skips the bundles list entirely: insert it directly in your own profiles/<name>/cordis.patch.yml — see Configuration.)

Usage

Nothing to invoke — it's a passive plugin. Boot your profile as usual (dsh web, dsh --profile headless "...", etc.) and the first turn of every new session goes out with the pruned tool list and preamble automatically.
