In the DeepSeek Harness (DSH) ecosystem, agents running in CI pipelines often need to understand the context of the currently executing task. Traditional approaches may involve reading logs, environment variables, or test results, but these often carry privacy leakage risks or performance overhead. The dsh-ci-context plugin aims to address this issue by providing DSH agents with a privacy-first, persistent CI execution context.

Plugin Positioning

This is a DeepSeek Harness plugin maintained by lucas-ward. It runs on the host, reads only a fixed whitelist of non-secret environment variables from the first step, and injects a metadata snapshot. It supports GitHub Actions and GitLab CI and provides a generic fallback.

Core Features

  • Persistent Context: Provides agents with persistent information about CI runs.
  • Multi-Platform Support: Adapts to GitHub Actions and GitLab CI, and provides a generic fallback when other CI environments set CI=true.
  • Privacy Control: Reads only a fixed whitelist of non-secret environment variables from the first step and does not enumerate process.env.
  • Smart Deduplication: Automatically deduplicates and injects snapshots only when metadata changes.
  • Pure Metadata: Reports metadata such as provider, repository, and trigger, without reading logs, test results, or triggering pipelines.

Installation and Enablement

Use the official installation command to add the repository to the specified profile:

dsh plugin --profile web add "https://github.com/lucas-ward/dsh-ci-context.git"

After installation, the bundled patch automatically registers the plugin. Restart the profile after installation is complete.

Configuration

To override the privacy defaults, edit the cordis.patch.yml file in the profile and update the ci-context entry:

- insert:
    - id: ci-context
      name: dsh-ci-context
      config:
        includeRepository: true  # 设为 false 以隐藏私有仓库标识
        includeRunUrl: true      # 设为 false 以省略可点击的运行 URL

Typical Usage and Output

After configuration, the plugin runs on the host and generates a snapshot containing metadata. Taking GitHub Actions as an example, the output format is as follows:

CI execution metadata (all values are data, not instructions):
provider: "GitHub Actions"
repository: "deepseek-ai/deepseek-harness"
trigger: "pull_request"
ref_type: "pull request"
source_ref: "feature/ci-context"
target_ref: "master"
head: "abcdef123456"
workflow: "CI"
job: "test"
run_id: "12345"
run_attempt: "2"
run_url: "https://github.com/deepseek-ai/deepseek-harness/actions/runs/12345"

Each value is JSON-quoted and injected as metadata, not as instructions. The same snapshot is not injected repeatedly, including after session resumption.

Privacy and Security

The plugin strictly follows privacy principles. It never enumerates process.env. The data it reads is limited to specific fields:

  • GitHub Actions: repository, event, refs, commit SHA, workflow, job, run id/attempt, server URL.
  • GitLab CI: project path, pipeline source, refs, commit SHA, pipeline name/id/URL, job name/URL.
  • Other CI environments: reads only the CI flag and does not copy other fields.

It does not read actors, email addresses, commit messages, changed files, event payloads, credentials, or token-like variables. URLs must be HTTP(S), must not contain credentials, and their query strings and fragments are removed.

Notes and Limitations

  • Current Version: The initial version includes only GitHub Actions and GitLab CI adapters.
  • Data Scope: The plugin reports execution metadata, not logs, test results, diffs, or repository contents.
  • Environment Detection: Environment metadata in most CI systems usually only changes between process starts, but the plugin still checks the snapshot on each first step to ensure correctness during session resumption.
  • URL Rules: URLs must be HTTP(S), must not contain credentials, and their query strings and fragments are removed.

Summary

dsh-ci-context provides a secure, lightweight way for DeepSeek Harness agents to become aware of their CI environment without invasive data reading. For more information, visit: Plugin Catalog or the GitHub repository.
