Diagnostics writethrough: after every successful edit or write (DSH's built-ins or omp-edit), the touched files are synced to their language server. Fresh errors and warnings are appended to the tool result, so the agent sees what it just broke:
```
The file src/a.ts has been updated successfully.

LSP diagnostics after this edit (1 error, 0 warnings):
src/a.ts:1:7 error [2322]: Type 'string' is not assignable to type 'number'. (typescript)
```
lsp agent tool:

Action	Inputs	Result
`diagnostics`	`file` (path or glob)	All diagnostics with counts
`definition` / `type_definition` / `implementation` / `references`	`file`, `line`, `symbol`	`path:line:col: source line` list
`hover`	`file`, `line`, `symbol`	Type/doc text
`symbols`	`file`, or `file="*"` + `query`	Document outline / workspace symbol search
`rename`	`file`, `line`, `symbol`, `new_name`, `apply`	Applies the rename across the workspace (`apply=false` previews)
`rename_file`	`file`, `new_name`, `apply`	Moves the file and updates imports when the server supports it
`code_actions`	`file`, `line`, `query`, `apply`	Lists actions; `apply=true` applies the first match
`status` / `reload` / `capabilities`	—	Installed/running servers, restart, server capabilities
`request`	`file`, `query` (method), `payload` (JSON)	Raw LSP request

symbol locates the column on the line: bare identifiers match on word boundaries, other text as a substring, and name#2 picks the 2nd occurrence.

Language servers

They're auto-detected on PATH, ~/.local/bin and the project's node_modules/.bin. There's one client per (server, project root), found from the nearest root marker, and idle servers stop after idleMinutes.

id	Command	Files	Install
typescript	`typescript-language-server`	ts tsx js jsx mjs cjs	`npm i -g typescript-language-server typescript@5`
pyright	`pyright-langserver`	py pyi	`npm i -g pyright`
gopls	`gopls`	go	`go install golang.org/x/tools/gopls@latest`
rust-analyzer	`rust-analyzer`	rs	`rustup component add rust-analyzer`
clangd	`clangd`	c h cc cpp hpp	distro package `clangd`
bash	`bash-language-server`	sh bash zsh	`npm i -g bash-language-server`
json / css / html	`vscode-*-language-server`	json, css/scss/less, html	`npm i -g vscode-langservers-extracted`
yaml	`yaml-language-server`	yaml yml	`npm i -g yaml-language-server`

Without root access, install the npm ones into ~/.local:

npm i -g --prefix ~/.local typescript-language-server typescript@5 pyright bash-language-server yaml-language-server vscode-langservers-extracted

TypeScript 7 (the Go port) ships no tsserver.js, so keep typescript@5 for the language server. If a project has no local typescript dependency, the plugin points the server at the global install.

Installation

dsh plugin --profile web add git+https://git.rizzy.dev/DSH-Plugins/omp-lsp.git

Or go to Settings → Plugins → Install with the same URL, or ask the agent to use plugin_manager → install_bundle.

For development:

git clone https://git.rizzy.dev/DSH-Plugins/omp-lsp.git ~/dsh-plugins/omp-lsp
dsh plugin --profile web add link:$HOME/dsh-plugins/omp-lsp

Then restart DSH (systemctl --user restart dsh or re-run dsh web), and check with lsp action=status in a new session.

Configuration

Set options in config of the omp-lsp row in ~/.dsh/profiles/web/cordis.patch.yml:

- id: omp-lsp
  config:
    writethrough: true              # append diagnostics to edit/write results
    writethroughTools: [edit, write]
    minSeverity: 2                  # 1 error, 2 +warnings, 3 +info, 4 +hints
    budgetMs: 4000                  # max wait for fresh diagnostics per write
    maxDiagnostics: 25
    idleMinutes: 10
    disabled: [html]                # server ids to turn off
    servers:                        # override or add servers
      lua:
        command: lua-language-server
        args: []
        extensions: [.lua]
        roots: [.luarc.json]
        languageId: lua
