skill-scan

A configurable skill discovery provider for DeepSeek Harness (DSH), designed as a drop-in replacement for the fixed dsh-skill-filesystem discovery strategy.

Instead of a hardcoded list of roots, skill-scan lets you toggle four scan layers and freely edit the "parent directories" under which <root>/<name>/skills is scanned, each with its own priority. An install wizard offers replace (disables the built-in provider) or coexist on first run.

Features

Layer	Priority	Where it scans
cwd (session working directory)	Highest	<cwd>/<parent-dir>/skills
project (nearest .git ancestor)	Medium — exclusive with ancestors	<project>/<parent-dir>/skills
ancestors (walk up from cwd)	Medium — exclusive with project	each ancestor's <parent-dir>/skills
global (user home ~)	Lowest	~/<parent-dir>/skills

• Editable parent dirs — default .dsh, .agents; add/remove/rename freely, and drag to reorder priority (top = highest).
• Mutual exclusivity — project scanning and ancestor walking can only have one enabled (validated in both UI and host).
• Skill format — directory bundles (<name>/SKILL.md) and flat Markdown files (<name>.md); frontmatter parses name, description, whenToUse, disable-model-invocation, user-invocable.
• Duplicate resolution — distinct names load from every layer; a same-named skill keeps only the highest-priority (smallest rank) one.
• Live invalidation — model write/edit touching a <…>/skills/ path invalidates the catalog immediately.
• Collapsible plugin card — Settings → Plugins → Plugin configuration, visually identical to the built-in cards (same --dsw-alias-* tokens and chevron).

Install

From npm (online)

dsh plugin --profile <profile> add @sidleo3/skill-scan

dsh plugin forwards its arguments to pnpm inside the profile and activates any package declaring dsh.bundle. After install, refresh the web GUI.

From a checkout (local link)

git clone https://github.com/sidleo/skill-scan.git
dsh plugin --profile <profile> add link:<repo-path>

Git-hosted installs (pnpm add github:user/repo) require adding the package under allowBuilds in the profile's pnpm-workspace.yaml (pnpm 10+).

First-run wizard: replace vs coexist

When you open the plugin card for the first time, choose:

• Replace — copies your current preset to a user preset named skill-scan and disables the skill-filesystem row inside the copy. The original preset stays untouched; new sessions that pick the skill-scan preset use your priority configuration for duplicate names. Fully reversible (a "restore" action deletes the copy).
• Coexist — leaves the preset alone; skill-scan only appends extra scan roots.

Why replace matters: DSH resolves same-named skills by layer before rank. If the built-in skill-filesystem stays mounted in the preset layer, it wins any duplicate name regardless of your rank — so for priority-over-duplicates behavior you must replace.

Configuration

All settings live in the plugin card (Settings → Plugins → Plugin configuration → 技能扫描):

• Four layer toggles.
• Parent dirs list with drag-to-reorder priority and per-row remove.
• Live root preview for the current session cwd.
• Debug panel that lists what discovery actually finds.
• Save writes back and refreshes the catalog.

Open-source status

This repository is the formal-package home of logic first verified live in a DSH dynamic plugin (skf-1). The src/ directory is the canonical package; skill-scan-blueprint/ keeps the original, dynamic-plugin-form sources as a reference (host / client / wizard).

To publish yourself:

pnpm install
pnpm build      # tsdown → lib/index.js + lib/client.js
npm publish

The host half depends on DSH-private packages (@deepseek-ai/dsh-skill, @deepseek-ai/dsh-agent-presets, …). Build from an environment where those resolve (they are published as -rc on npm); this package declares them as peerDependencies/devDependencies.
