-Runnable demos (not workspaces) that showcase how the harness is wired. Each example is a **thin leaf**: a `cordis.yml` that picks swappable backends, loads one app package, and may add optional product tools. The composition and boot glue live in [`@deepseek-ai/dsh-tui-demo`](../packages/examples/tui-demo), [`@deepseek-ai/dsh-cli-demo`](../packages/examples/cli-demo), [`@deepseek-ai/dsh-acp-demo`](../packages/examples/acp-demo), and their shared [`@deepseek-ai/dsh-agent-spine-demo`](../packages/examples/agent-spine-demo) bundle. There is no `start.ts`; the terminal `demo:*` scripts boot through the [`dsh`](../apps/cli/README.md) CLI (which mounts the `tui-demo` bundle), and the headless/ACP scripts invoke the `cli-demo`/`acp-demo` bins.
+Runnable demonstrations of the main DeepSeek Harness interfaces and extension points. Each child directory owns its configuration, prerequisites, commands, and detailed behavior.
+
+## mcp-memory
+
+Optional overlays that connect supported third-party memory servers through the generic MCP client. See the [memory example reference](mcp-memory/README.md).

 ## headless-agent

-A non-interactive agent demo that accepts one positional task, runs one complete model/tool turn on the `@deepseek-ai/dsh-cli-demo` app, persists a fresh session, prints `text`, `json`, or `stream-json`, and exits.
-
-Run with: `pnpm run demo:headless "task"` (needs `DEEPSEEK_API_KEY`). See [headless-agent/README.md](headless-agent/README.md) for the output contract, safety boundaries, and snapshot suite.
-
-## tui-agent
-
-The interactive coding agent: DeepSeek V4, filesystem and bash tools, subagents, workflows, `todo_write`, compaction, and the full-screen TUI. It is also the home of TUI PTY and snapshot scenarios.
-
-Run with: `pnpm run demo:tui` (needs `DEEPSEEK_API_KEY`). Run its Code Mode overlay with `pnpm run demo:code-mode`. See [tui-agent/README.md](tui-agent/README.md) for controls and composition.
+A non-interactive agent that accepts one task, runs it, and emits a selected machine-readable or human-readable output format. See the [headless example reference](headless-agent/README.md).

 ## jsonrpc-agent

-An unattended coding agent driven through the Python SDK: JSON-RPC stdio, foreground-only `bash`, `read` / `write` / `edit`, one foreground `subagent`, `todo_write`, JSONL persistence, and compaction. It excludes terminal UI, stdout logging, approvals, skills, and background task controls. See [jsonrpc-agent/README.md](jsonrpc-agent/README.md).
+An unattended coding agent driven through the Python SDK and JSON-RPC. See the [JSON-RPC example reference](jsonrpc-agent/README.md).

-## cordis-agent
+## web-cordis

-The **self-referential** demo: the coding spine plus [`@deepseek-ai/dsh-tool-cordis`](../packages/cordis/tool-cordis), whose three tools (`cordis_inspect` / `cordis_mount` / `cordis_unmount`) let the agent inspect the current DSH process, mount model-written temporary Plugins (an event listener, a brand-new tool, or a service another temporary Plugin injects), and unmount them again. These Plugins exist only in memory and share one internal `cordis-dynamic` fiber subtree; `ctx.fs`/`ctx.web` ride along provider-only as capabilities they can use.
-
-Run the TUI with `pnpm run demo:cordis`, the browser UI at `http://127.0.0.1:3081` with `pnpm run demo:cordis web`, or the ACP server with `pnpm run demo:cordis acp` (all need `DEEPSEEK_API_KEY`). See [cordis-agent/README.md](cordis-agent/README.md) for the staged demo script and [the toolset Agent Note](../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.md) for the design and sandbox caveats.
+A self-referential agent that can inspect and change its in-memory Cordis plugin tree. See the [web-cordis example reference](web-cordis/README.md).

 ## acp-agent

-An agent exposed as an **Agent Client Protocol (ACP)** automation server over JSON-RPC stdio, via [`@deepseek-ai/dsh-acp-demo`](../packages/examples/acp-demo). Programmatic clients create fresh sessions, send text prompts, consume committed assistant text, answer one-shot permission requests, and cancel work. It owns the ACP keyless snapshot suite.
-
-Run with: `pnpm run demo:acp` (needs `DEEPSEEK_API_KEY`); `pnpm run demo:code-mode acp` boots the same server in Code Mode via the `code-mode.cordis.yml` overlay. See [acp-agent/README.md](acp-agent/README.md) for the protocol and snapshot-test contracts.
-
-The default `cordis.yml` composes [`@deepseek-ai/dsh-sandbox-local`](../packages/sandbox/sandbox-local), [`@deepseek-ai/dsh-bash-sandbox`](../packages/bash/bash-sandbox), and [`@deepseek-ai/dsh-user-approval`](../packages/ui/user-approval). `workspace-write` confines bash and filesystem mutations to each session workspace; a wider retry becomes a one-shot machine permission request over ACP.

 ## Session workspaces and permissions

-Each `session/new` supplies an absolute `cwd`. Sandboxed bash and filesystem mutations resolve `workspace-write` against that session cwd, so concurrent sessions can use separate project roots; platform temporary roots remain shared writable scratch space ([sandbox contract](../../packages/sandbox/sandbox/README.md)). `DSH_PERMISSION_MODE` selects `workspace-write` or `danger-full-access` for deployment and tests.
+Each `session/new` supplies an absolute `cwd`.

 Under `workspace-write`, a model retry requesting wider sandbox access triggers `session/request_permission` with `allow_once` and `reject_once`. The client decides programmatically; dismissal or an unavailable answer fails closed. The selected outcome applies only to that retry and is recorded through the normal tool-result/audit path. The server never exposes a permission picker or persists client policy.

-## Snapshot tests
-
-This example owns the ACP snapshot suite. It boots the real automation server, replays committed model streams through `dsh-llm-replay`, and compares both normalized protocol output and re-persisted session logs. Recording uses the real model; refresh reuses committed replay input. Overrides cover throw/hang behavior, and optional `workspace/` fixtures seed world-state checks.
-
-Most scenarios pin backend behavior rather than ACP-specific behavior; the [automation-only ACP decision](../../.agents/notes/implemented/simplification/2026-07-23-acp-automation-only-protocol.md#snapshot-boundary) owns why that coverage remains transport-coupled.

 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.

 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.

 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it.

Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.

 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.

 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

-You are an AI agent powered by the DeepSeek Harness SDK.
-
-You are a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}. Your bash tool runs under a file sandbox — a `[sandbox: file access denied …]` result is policy, not a command bug.
-
-Verify your work by running the code or tests. Keep answers brief and factual.
-
-
-Use the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.
-
-Use the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.
-
-Use the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.
-
-Check the [exit code: N] marker on every bash result; investigate failures before moving on.
-
-Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
-
-Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
-
-<!-- dsh-user-approval-policy:ask -->
-
-Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
-
-Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

+You are an AI agent powered by the DeepSeek Harness SDK.
+
+You are a concise snapshot agent working in {{cwd}}.
+
+Use the glob tool — not shell find — to discover files by path pattern. A pattern with no "/" matches basenames at any depth, so "*" matches every file in the tree rather than its top level. Results are files only, never directories, and include hidden and ignored files: a result that fits comes back in modification-time order, while a larger one is sampled across top-level entries, so it spans the tree instead of one subtree.
+
+Use the grep tool — not shell grep or rg — to search file contents. Use read on a matched file when you need surrounding context.
+
+Check the [exit code: N] marker on every bash result; investigate failures before moving on.
