Implements docs/rfc/implemented/feature/2026-07-09-bash-backed-grep-glob- discovery.md: model-facing glob/grep in a new @deepseek-ai/dsh-tool-fs-search package, executing fixed ripgrep templates through ctx.bash.resolve/run — not ctx.fs provider methods — so filesystem backends stay free of a search contract and sandboxed/remote executors substitute cleanly. The tools never call ctx.bash.start(); the tool layer owns quoting (one singleQuote safety boundary), rg --json parsing, ItemRetainer/TextRetainer retention, and the first tool-owned ctx.spillFiles.saveText() handoff (item-level retention the generic post-execute spill policy cannot recover). RFC amendments on the way to implemented/: a shared src/search-core.ts (the SEARCH_* vocabulary + bash-run/raw-spill/spill plumbing was byte-identical across both tools — the missed-extraction smell), and a snapshot-gap note: wiring the acp-agent tree changes the assembled prompt, so goldens need a keyed re-record; the spill notice text is pinned by unit tests instead and only the coding-agent example ships the tools for now.
Examples
Runnable demos (not workspaces) that showcase how the harness is wired. Each example is now a thin leaf: a cordis.yml that picks the swappable backends (an LLM adapter, a bash executor), loads ONE app package, and may add optional product tools or demo-only mocks. The composition — the spine, the front-door cluster, and the boot glue — lives in the app packages (@deepseek-ai/dsh-stdio-agent, @deepseek-ai/dsh-acp-agent) and the @deepseek-ai/dsh-agent-core bundle they share. There is no start.ts; the demo:* scripts invoke each app package's bin.
echo-agent
A mock model + echo tool on the stdio chat app — the all-mock skeleton. The leaf swaps dsh-stdio-agent's LLM backend to a local mock-echo adapter and adds a local echo tool. Demonstrates:
- A thin leaf
cordis.ymlloading the@deepseek-ai/dsh-stdio-agentapp - Registering a mock
LlmAdapter(streaming scripted responses) - Registering a tool via
ctx.tools.register() - "Swap the backend, keep the app" — the only difference from
coding-agentis the adapter
Run with: pnpm run demo:echo. When prompted, type "echo " to trigger a tool call round-trip.
coding-agent
A REPL agent demo: DeepSeek V4 + the read/write/edit filesystem tools + the bash tool suite, subagent delegation, and the todo_write task tracker on the same @deepseek-ai/dsh-stdio-agent app. The UI is a terminal readline REPL.
Run with: pnpm run demo:repl (needs DEEPSEEK_API_KEY in the environment or a gitignored repo-root .env). See coding-agent/README.md for details.
acp-agent
An agent demo exposed as an Agent Client Protocol (ACP) server over JSON-RPC stdio, via the @deepseek-ai/dsh-acp-agent app — drive it from Zed or any other ACP client. Also the home of the keyless snapshot tests.
Run with: pnpm run demo:acp (needs DEEPSEEK_API_KEY). See acp-agent/README.md for the Zed setup and the snapshot-test design.
