feat(dsh): add DeepSeek Harness plugin - #1239
Merged

Conversation
Give DeepSeek Harness the same Server-backed recall and Memory tools as Codex, with a fail-open HTTP client and setup/doctor CLI.
CI quality failed because hooks rewrote tsconfig, generated lib files, and two Python sources.
The quality job has no Node toolchain. Leave plugin vitest on make js-test for local runs.

There was a problem hiding this comment.
Thanks for adding the DeepSeek Harness integration. I am requesting changes for two blocking issues: prompt capture currently loses message provenance, and the generic OpenAPI tool exposes operations beyond the intended agent-facing surface. Please address the inline comments before merging.

Rationale for this change
DeepSeek Harness is a supported agent host. PowerContext already has Codex and HTTP/MCP surfaces; this change adds a first-class DSH plugin so a running Server can recall bounded context and maintain Memory from
dsh webwithout embedding Python or MCP.What changes are included in this PR?
integrations/dsh/plugins/powercontext(powercontext-dsh): Cordis plugin that recalls viaPOST /v1/context/prepare, captures prompts as Source evidence, and exposes namedpc_*HTTP tools. Server or transport failures fail open.powercontext setup dshandpowercontext doctor dsh. Setup installs the plugin withdsh plugin --profile web add. Doctor checks that dump-config listsid: powercontext-dsh.lib/index.jsso a Git checkout can be loaded. On Windows, launchdsh.cmdand decode CLI output as UTF-8.openapi/powercontext.yaml(make js-api-generate/js-api-generate-check/js-test).Are there any user-facing changes?
Yes. New commands:
powercontext setup dshandpowercontext doctor dsh. New docs: Configure DeepSeek Harness. No Server API or storage format changes. Existing Codex setup is unchanged.How was this change tested?
