dsh-lens

The blind-write cycle is one of the most common pain points when an agent authors code: a file lands on disk with no immediate signal, and type errors, formatting drift, or cascading impact on neighboring modules only surface in the next turn or during a manual pass. dsh-lens ports the full pi-lens analysis engine into the DeepSeek Harness host so that every write, edit, or bash mutation automatically triggers a five-stage diagnostic pipeline, catching issues before they leak into the next model request.

The pipeline runs in sequence: safe autofix and formatting, LSP file sync and diagnostic collection, ast-grep / tree-sitter / fact-rule scanning, cascade diagnostics on likely neighbors, and turn-end blockers and advisories injected directly into the next request. The plugin also registers the complete agent-facing tool set (symbol_search, lsp_navigation, ast_grep suites, read_enclosing, module_report, and more), nine /lens-* session commands, four upstream pi-lens skills, and a WebUI chip with a composer dock on the official Web profile. Configuration stays in .pi-lens.json, so no new mental model is required.

If you drive code authoring through DeepSeek Harness and want write-time diagnostics, or you already know the pi-lens ecosystem and want a smooth hop to dsh, dsh-lens is the adapter layer in between. One caveat: do not attach pi-lens-mcp to the same workspace alongside dsh-lens, as that would double-start language servers.
