Qoder CN adapter plugin for DeepSeek Harness.
Installs the qoder-cn provider route: COSY-signed, WAF-encoded streaming against gateway.qoder.com.cn. A Qoder PAT (pt-...) is stored through the Models page and exchanged per process for a short-lived job token.
Requires DeepSeek Harness 0.2.1-alpha.1 or newer in the 0.2.x line and pnpm. Verified against the official 0.2.1-alpha.2 runtime.
dsh plugin --profile web add @lightmanlu/dsh-provider-qoder
dsh webOpen Settings → Models → Qoder CN → Edit connection. This card ships with the plugin and uses the official Models-page extension slot; no Harness source patch is required. Enter a PAT, and optionally an enterprise VPC instance ID. Leave the instance empty for the public CN cloud. Advanced settings allow explicit Gateway and OpenAPI URLs.
The card never reads back the PAT. Leaving its input empty preserves the existing credential; environment-owned credentials are read-only. Connection changes take effect on the next request. If configuration saves but credential storage fails, the card keeps the token draft and reports the partial save for retry. A stale configuration revision is rejected before writing a token.
The unscoped npm package dsh-provider-qoder belongs to a different project. This implementation is published as @lightmanlu/dsh-provider-qoder; github:minglu6/dsh-provider-qoder remains an alternative source. To link a local checkout after building:
npm install
npm run build
dsh plugin --profile web link /absolute/path/to/dsh-provider-qoderRestart the Web profile after installing or rebuilding the plugin's browser bundle.
For Desktop, fully quit the application and replace --profile web with --profile desktop. When migrating this implementation from an older GitHub/tarball install named dsh-provider-qoder, replace that dependency and its dsh.profile.bundles entry with the scoped name; also update the existing llm-qoder entry's package name to @lightmanlu/dsh-provider-qoder. Preserve that entry's connection configuration, credential references, and all credential storage. Do not load both names at once.
Remove:
dsh plugin --profile web remove @lightmanlu/dsh-provider-qoderFrom a DeepSeek Harness checkout:
pnpm dsh plugin --profile web add @lightmanlu/dsh-provider-qoder
pnpm dsh webThe bundle mounts the llm-qoder entry. Its live configuration is persisted through DSH's profile cordis.patch.yml, and PATs are stored through the DSH credentials service. The default credential reference is QODERCN_PERSONAL_ACCESS_TOKEN; a launch environment can supply that reference instead.
An existing providers.qoder-cn profile overrides only the fields it declares and inherits other root fields. The card edits that profile when present, otherwise the root. An explicit empty VPC instance selects public cloud instead of an inherited or environment-provided tenant. Empty URL overrides derive endpoints from the selected VPC or public cloud. Advanced configuration and model overrides not edited by the card are preserved.
Unless models is configured, the adapter fetches Qoder's signed live catalog from /algo/api/v2/model/list whenever DSH lists the provider. Model IDs are the upstream key, and labels are the upstream display_name (or the key when no name is supplied). Generation sends that same key unchanged in its headers and body. Distinct keys remain distinct even when their display names match.
Exact-model resolution reuses the latest successful catalog in the current process. The DSH browser also caches its model selector catalog: opening the menu repeatedly does not poll Qoder. Reload the page to request a fresh catalog, or let settings, credentials, or adapter changes trigger its refresh.
models remains an optional complete static override for deployments that intentionally pin the selector catalog. Every configured id must be an upstream wire key. This list replaces live discovery rather than extending it. Authentication failures surface as AUTH (and a rejected job-token session is dropped and retried once after a fresh exchange), transport, invalid JSON, and empty-catalog failures surface as discovery errors instead of falling back to a built-in list.
Saved selections or static catalogs using versioned aliases such as qwen3.6-flash, kimi-k2.6, or glm-5.2 must be reselected from the live directory or changed to the intended upstream key. Do not infer the key from an old version label: Qoder can rename or replace the model behind a key. auto is unchanged. Historical session logs are not rewritten. The getQoderCNDirectModel helper is no longer exported; callers send the selected upstream key directly.
Qoder can reject tool results when the preceding assistant message contains only tool calls and has content: null. The adapter adds a non-empty (tool call) marker to that assistant message on the wire, preserving call IDs, arguments, result order, and stored session history. Existing text and reasoning remain unchanged. After installing the updated plugin and restarting the Host, affected conversations can be retried without rewriting their history.
In-band upstream errors expose the nested provider message and gateway request ID rather than truncating the JSON wrapper before the actionable detail. Error classification and authentication retry behavior are unchanged.
The adapter incrementally recognizes <thinking>, <think>, <reasoning>, and <thought> across stream boundaries, even if upstream emits them with reasoning disabled. Ordinary text, whitespace, native reasoning, and structured tool calls are preserved.
A normal stop containing only reasoning, or unclosed tagged reasoning without a structured tool call, finishes with QODER_INCOMPLETE_RESPONSE rather than reporting success. Partial reasoning remains available as evidence; orphan DSML fragments are not converted into invented tool calls. Real tool calls and length-limit termination retain their normal behavior. This guard does not retry requests or replay tools.
Remote session identity is scoped to the gateway, account, provider route, model, harness sessionId, and request purpose. Compaction and session-title calls do not share the foreground conversation's remote session. Requests without a harness session get a fresh identity; request-record IDs also include the serialized messages, tools, prompt, and generation settings.
For ordinary conversations, the adapter quarantines the specific unsolicited <analysis>…</analysis><summary>…</summary> checkpoint scaffold containing at least three recognized English/Chinese checkpoint headings. Fragmented tags and Markdown quote separators are supported; ordinary XML examples and answers following a checkpoint are preserved. Quarantined output is not exposed as answer text, and generation is retried once with the original history/tools, a fresh remote session, and an instruction to complete the task. The adapter never executes or replays tools. Another checkpoint finishes with QODER_UNEXPECTED_SUMMARY, not a successful stop; upstream failures and cancellation retain their original semantics.
Harness requests explicitly marked purpose: 'compaction' or 'session-title', and user-requested summaries, bypass this output safeguard. DSH compaction can carry the foreground tool declarations, so tool presence is not used to identify it. The guard is not a general XML filter or a fix for the gateway's internal summarization behavior. Recovery may incur one additional model request.
npm ci
npm test
npm run typecheckThe build emits the Host adapter and a lazy-CJS browser bundle under dist/. Both are included in the package and tracked for direct GitHub installation. The adapter accepts the official request-message format, including standalone role: tool results.
