# DeepSeek Harness (dsh) Setup

[DeepSeek Harness](https://github.com/deepseek-ai/deepseek-harness) (`dsh`) is DeepSeek AI's
open-source agent harness — an "everything is a plugin" architecture with a Web UI, started with
`npx @deepseek-ai/dsh web`. It natively loads [Agent Skills](https://agentskills.io) and reads
`AGENTS.md`, so all six brooks-lint modes run with no conversion.

## Install

```bash
# simplest — one command (global)
curl -fsSL https://raw.githubusercontent.com/hyhmrright/brooks-lint/main/scripts/install.sh | bash -s -- dsh

# from a clone
./scripts/install.sh dsh            # global: ~/.dsh/skills (or $DSH_HOME/skills)
./scripts/install.sh dsh --project  # this repo: ./.dsh/skills
```

Prefer a manual copy? Clone the repo and `cp -r skills/* ~/.dsh/skills/` — the contents, not the
`skills/` folder itself, so `_shared/` lands as a sibling of the `brooks-*` folders.

dsh scans these skill roots, highest priority first, so an existing vendor-neutral install is picked
up automatically:

| Root | Notes |
|---|---|
| `<projectRoot>/.dsh/skills` | what `--project` writes |
| `<projectRoot>/.agents/skills` | shared with Cursor, Copilot, pi |
| `$DSH_HOME/skills` (default `~/.dsh/skills`) | what the global install writes |
| `$DSH_AGENTS_HOME/skills` (default `~/.agents/skills`) | `./scripts/install.sh agents` also covers dsh |

The project root is the nearest ancestor containing `.git`; without one, dsh uses the current
directory. When the same skill name appears in two roots, the higher one wins.

## Invoke

Just ask — dsh routes to a skill from its `description`:

- "review this PR" → `brooks-review`
- "audit the architecture" → `brooks-audit`
- "where's our worst tech debt?" → `brooks-debt`

For explicit invocation, type `/` in the Web UI prompt and pick the skill, or type the token by hand:
`/brooks-review`, `/brooks-audit`, `/brooks-debt`, `/brooks-test`, `/brooks-health`, `/brooks-sweep`.
dsh recognises a whitespace-bounded `/name` anywhere in a message and injects that skill's body
deterministically. The repo's `AGENTS.md` carries the Iron Law (Symptom → Source → Consequence →
Remedy) and the Health Score rules; dsh also loads `$DSH_HOME/AGENTS.md` plus every `AGENTS.md` from
the project root down to your working directory.

## Notes

- **Flat layout** is mandatory (the installer guarantees it): discovery is one level deep
  (`<root>/<name>/SKILL.md`), never recursive, and the skills read `../_shared/`, which only resolves
  when `_shared/` sits beside the `brooks-*` folders. `_shared/` itself has no `SKILL.md`, so dsh
  ignores it as a skill and the modes read it as ordinary files.
- dsh is in developer preview and warns of compatibility-breaking changes; the skill discovery
  contract above reflects `packages/skill/skill-filesystem` as of August 2026.
