dsh-irmia-devkit

Curated Irmia DevKit tools for DeepSeek Harness (DSH). Nine battle-tested tools ported as-is from Irmia DevKit v2.6.4, covering the gaps the Harness runtime does not ship natively.

Features

Group	Tools	What they do
Safe editing	safe_edit · safe_rollback · multi_edit	Backup → edit → syntax gate → auto-rollback on failure. safe_rollback(list=true) lists backups; multi_edit does atomic cross-file batch edits
Networking	http_get · http_post	SSRF-guarded HTTP (private-network blocking + per-hop redirect re-check)
Code understanding	code_index · code_explore · code_diff_impact	Symbol indexing (AST + SQLite + FTS5) with BFS call-graph queries; code_index(status=true) checks index health
Read-only DB	db_query	SELECT/PRAGMA whitelist + engine-level mode=ro read-only

Zero third-party Python dependencies — pure standard library (chardet / tree-sitter are optional enhancements with graceful fallback).

Install

Requires Node.js ≥ 18 and python3 (≥ 3.9) on PATH. This package ships as a DSH bundle (dsh.bundle), installed into a profile via dsh plugin:

# From npm (recommended)
npx @deepseek-ai/dsh plugin --profile web add dsh-irmia-devkit

# From GitHub (pin a version)
npx @deepseek-ai/dsh plugin --profile web add github:irmia2026/dsh-irmia-devkit#v0.1.0

Verify the layer landed before launching:

npx @deepseek-ai/dsh --profile web --dump-config   # look for a "# == dsh-irmia-devkit" layer
npx @deepseek-ai/dsh web

Configuration

Field	Default	Description
pythonPath	python3	Executable used to run the bundled Python tools

How it works

Model → Cordis tool (index.js / src/tools.js)
        │  execFile("python3", python/runner.py <tool> '<json-args>')
        ▼
python/runner.py → python/tools/*.py (DevKit modules, unchanged)
        ▼
JSON result back to the model

• The JS layer only defines tool schemas and bridges to subprocesses.
• The Python core comes from irmia_devkit_open v2.6.4, unmodified.
• Per-tool behavior (arguments, guards, return protocol) is preserved exactly.

Development

node test/smoke.mjs   # requires node_modules with @deepseek-ai/dsh-tools
