Native A2A (Agent-to-Agent) server for dsh: expose this dsh as a callable agent over HTTP with JSON-RPC tasks.
Install
# from npm (prebuilt)
dsh plugin --profile web add dsh-plugins-a2a
# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)
dsh plugin --profile web add github:kouyichi/dsh-plugins#path:/dsh-a2a
Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).
README
This plugin publishes its README in Chinese only.
把 dsh 暴露为 A2A v1.0（Agent-to-Agent，JSON-RPC over HTTP）agent——其他 agent（Hermes 等）可直接调 tasks/send 让本 dsh 干活。生态空白：截至 2026-08-16 无第三方 A2A server（官方示例只覆盖 ACP/JSON-RPC）。

协议
tasks/send{id, message:{role, parts:[{type:"text",text}]}} → Tasktasks/get/tasks/cancel/tasks/list/agent/get
每个任务独立 agent 执行（会话落盘可审计）。token 优先读 DSH_A2A_TOKEN 环境变量；DSH_A2A_AUTOSTART=1 可在启动时自动开。
示例（curl）
curl -s -X POST http://127.0.0.1:9917 -H 'content-type: application/json' \
-d '{"jsonrpc":"2.0","id":1,"method":"tasks/send","params":{"id":"t1","message":{"role":"user","parts":[{"type":"text","text":"运行 echo hello"}]}}}'
