Preface

The plugin ecosystem of DeepSeek Harness (DSH) emphasizes “everything is a plugin,” and the community directory is an independent site with no official affiliation to DeepSeek / High-Flyer. For those engaged in agent development within DSH, common questions when integrating external skill libraries include: whether skill files are distributed with the package, whether they need to be configured one by one, and whether they can be loaded directly by the skill tool.

gongyijie85/dsh-ecc addresses this problem: it ports ECC (227k-star operator system) skills to the DeepSeek Harness plugin architecture, registers skill providers to the ctx.skills registry, distributes skills with the package, and requires no individual configuration from users.

What is this

dsh-ecc is a DSH plugin maintained by gongyijie85, unofficially ported from affaan-m/ECC. The license is:

MIT

Current version:

0.5.0

It primarily does two things: register ported ECC skills into DSH’s skill system; distribute these skill files with the package as DSH plugins.

Core Features

The plugin registers skill providers to the host layer, involving the registry:

ctx.skills

After registration, skill files are distributed with the package at a fixed path:

skills/<name>/SKILL.md

Users do not need extra configuration.

Skills are ported in batches. Verified batches are as follows:

  1. v0.1.0: 20 initial skills, covering engineering methodologies, Agent systems, engineering foundations, patterns & data, research & optimization.
  2. v0.2.0: 68 pattern-based skills, covering frontend, backend frameworks, language patterns, data & architecture.
  3. v0.3.0: 50 orchestration/automation/ops skills.
  4. v0.4.0: 135 vertical domain and all remaining portable skills, covering medical, home networking, science, finance, design & content, network ops, supply chain/logistics, marketing/sales, research & data, etc.
  5. v0.5.0: Added tasteforge-video skill, supporting style interview, style pack, validation, application, and EDL/FCPXML export.

The cumulative ported count is:

274/286

Regarding runtime:

  • Zero runtime dependencies.
  • Native parsing of folded YAML frontmatter.
  • Accessible by all models/users.

Installation and Enablement

Below are verified GitHub installation commands. The repository README also lists npm and local development methods; the npm package name dsh-ecc is occupied by a project with the same name, so this package is published as:

dsh-ecc-skills
  1. Add plugin:
dsh plugin --profile web add github:gongyijie85/dsh-ecc
  1. Restart profile:
dsh web
  1. Load skills via the skill tool:
skill

If you want to add or debug skills locally, you can put the files in:

skills/<kebab-name>/SKILL.md

The documentation states that placing them will trigger auto-discovery.

Verification command:

npm run verify

The verification example given in the documentation is:

274/274

Use Cases and Notes

Suitable for the following usage:

  • Using DSH’s web profile.
  • Want to integrate ECC skills into the skill tool.
  • Want skills distributed with the plugin package rather than maintaining multiple skill files separately.

Please note:

  • This package is an unofficial port. Skill content is adapted from affaan-m/ECC (MIT, © Affaan Mustafa).
  • License is MIT; copyright for the DSH port belongs to dsh-ecc contributors.
  • ECC’s Claude Code exclusive infrastructure (agents/hooks/commands/mcp-configs) is not included in this package.
  • The plugin runs with the permissions of the current dsh process. You should check the source code and license before installing.
  • The community directory is an independent site and should not be interpreted as an official app store.

Conclusion

The value of dsh-ecc lies in integrating ECC skills as DSH plugins, reducing the manual configuration cost for single-file skills. If you want to invoke these skills via the skill tool in DSH, you can start with the installation commands above.
