dsh-lens

Real-time code feedback for DeepSeek Harness: LSP, linters, formatters, type-checking, and structural analysis while the agent writes.

Current release: dsh-lens@0.2.0.

What it does

This is a host-native port of pi-lens. The analysis engine stays in pi-lens; this plugin is the DeepSeek Harness adapter.

On every write / edit / bash mutation it runs the same pipeline pi-lens uses inside Pi:

1. format queue / safe autofix
2. LSP file sync and diagnostics
3. ast-grep, tree-sitter, fact rules, and language scanners
4. cascade diagnostics on likely neighbors
5. turn-end blockers and advisories injected into the next model request

It also registers the full agent-facing tool set, the /lens-* commands, bundled pi-lens skills, and a WebUI chip/dock.

Standalone CLI (review graph, same as pi-lens build-graph):

npx dsh-lens build-graph --cwd .
npx dsh-lens status

Install

dsh plugin --profile web add dsh-lens

Or from git:

dsh plugin --profile web add github:NexusAgentX/dsh-lens

Do not also attach pi-lens-mcp / official MCP-wrapped pi-lens against the same workspace — that double-starts language servers.
