Greenfield #2 "建插件" modules for the forthcoming `dsh-sdk create <source>` command, in a new foundation-independent package so it touches none of the dsh-scripts / dsh-helper / create-sdk hotspots the foundation refactor edits. - `resolvePluginSource(spec)` parses `owner/repo[/subdir]#ref` (github) or `pkg@version` (npm) into a `PluginSource` discriminated union, failing loud on an ambiguous or malformed spec. - `PluginFetcher<S>` seam + `fetchPlugin` tag dispatch returning a common `FetchedPlugin` (temp dir + immutable provenance). - `GigetFetcher` (github) over @bluwy/giget-core: resolve `#ref` to a commit SHA first, download that SHA; provenance pins the SHA. Chosen over unjs/giget for its single runtime dep and absent install/action surface. - `PacoteFetcher` (npm) over pacote: resolve the manifest, then extract the tarball verified against its registry integrity. Registry-only is enforced by the source resolver; extract runs no lifecycle scripts. - Branded `CommitSha`/`Integrity`; network + temp-dir boundaries are injected so the logic is unit-tested at 100% per-file coverage without network. Wiring (package.json pin, cordis.yml via ProjectEditSession with a confirmed diff, install --ignore-scripts) and the launcher command registration land later with the foundation.
DeepSeek Harness
English | 中文
The DeepSeek Harness SDK is a plugin-based SDK for building agent harnesses.
Development
This monorepo is built on the Cordis framework (vendored as source under vendor/), microkernel-style: everything is a plugin.
pnpm install
pnpm run test # vitest
pnpm run demo:repl # REPL agent demo (needs DEEPSEEK_API_KEY)
pnpm run demo:acp # ACP server agent demo (needs DEEPSEEK_API_KEY)
For humans, start with the development guide for local setup, hooks, environment variables, and quality gates, then read the architecture design and documentation graph index before package work. Local context lives in packages/ and vendor/.
For agents, follow AGENTS.md.
