Research date: +2026-10-11. Versions examined locally: codex-cli 0.162.1, opencode 2.0.18. Claude Code was not run (see QA). + +Boundary (unchanged from #329): the provider owns the model, the agent loop, reasoning, context and compaction, +native tools, sandbox and approval policy. NMSh owns presentation, navigation, input ownership, target switching and +the person's approval answers through a supported channel. NMSh never scrapes a TUI, never calls a model API and +never approves on the person's behalf.

a + WebSocket transport is documented as experimental and unsupported). +- Handshake: `initialize` with `clientInfo {name, title, version}`, then the `initialized` notification. +- Threads and turns: `thread/start {cwd}` (or `thread/resume {threadId}`) returns `{thread: {id}, model, …}`; + `turn/start {threadId, input: [{type: "text", text, text_elements: []}]}` returns `{turn: {id}}`; + `turn/interrupt {threadId, turnId}`. +- Events: `turn/started`, `item/started`, `item/completed` (item types include `agentMessage`, `commandExecution`, + `fileChange`, `mcpToolCall`, `reasoning`, `plan`), `turn/completed {turn: {status: completed | interrupted | + failed, error?: {message}}}`, plus deltas, token usage and plan updates. +- Server requests needing an answer: `item/commandExecution/requestApproval` and `item/fileChange/requestApproval` + (decisions include `accept`, `acceptForSession`, `decline`, `cancel` and policy amendments), and others + (`item/tool/requestUserInput`, `mcpServer/elicitation/request`, `item/permissions/requestApproval`, …). + +### What this PR implements (`src/agents/sessions/codexAdapter.ts`) + +A `CodexSession` with the same contract as `ClaudeSession` (`TargetAdapter`: start, send, answer, cancel, close): + +- spawns `codex app-server` with the person's own configuration: NMSh does **not** override Codex's approval + policy, sandbox or model; +- queues messages sent before the thread exists; reports the thread once whether `thread/started` or the + `thread/start` response arrives first; +- answers approvals only with the person's explicit choice, as `accept` (this one) or `decline`, never + `acceptForSession` or a policy amendment;

Both files are changed by the managed-agent workspace PR (#347); adding a + `codex-app-server` control there belongs after #347 lands, so this PR adds only the adapter. +- Plans (`turn/plan/updated`) and token usage are documented but not normalized yet: they need the provider-owned + task model in #332/#339 rather than a Codex-only shape. +- Physical QA with a signed-in Codex account (see below). + +## OpenCode (`opencode serve`) + +Source: opencode.ai/docs/server and `opencode serve --help` (2.0.18). The server is a local HTTP API (default +`127.0.0.1:4096`, optional basic auth via `OPENCODE_SERVER_PASSWORD`) publishing an OpenAPI 3.1 document at `/doc`, +with sessions, messages, `prompt_async`, `abort`, permission responses and an SSE stream at `/event`. 2.0.18's +`serve` describes itself as "the v2 API" and adds `--stdio` and `--service`, while the server documentation page +still describes the v1 endpoints and points to "a newer OpenCode v2" without saying how the API changed. + +Decision: **no adapter yet.** The documented endpoints are enough for a design, but the event payloads are not on +the server page and the v1/v2 relationship is unclear. The next step is to read the running server's `/doc` for an +installed version (a local probe the person starts) and pin an adapter to that schema the way the Codex adapter is +pinned to its generated schema. Until then OpenCode stays "shown, not controlled", as `harnesses.ts` says. + +## Claude Remote Control (#340) + +Source: code.claude.com/docs/en/remote-control (read 2026-10-11). + +Documented facts: + +- Started explicitly with `claude remote-control` (server mode), `claude --remote-control`/`--rc` (an interactive + session) or `/remote-control` (`/rc`) inside one; optionally automatic for every **interactive** session + (`remoteControlAtStartup`, or `/config`). +- Requires claude.ai subscription authentication (Pro, Max, Team, Enterprise; an Owner must enable it on Team and + Enterprise).

Organizations can require Trusted Devices; devices are listed + and revocable in account settings. `disableRemoteControl` turns it off; ZDR and HIPAA configurations disable it. +- One remote session per interactive process outside server mode. + +Not documented: whether a `--print` stream-json session (NMSh's Managed transport) can register for Remote +Control, or how a remote message would interleave with a host-driven stream-json conversation. + +Go/no-go: + +- **Managed targets: no-go.** The transport NMSh drives is not documented as Remote Control capable, so NMSh offers + no Remote Control option for Managed targets and does not add `--remote-control` to their arguments. +- **Raw (native) Claude: supported by Claude itself.** Running `claude --remote-control` in the shell, or `/rc` + inside Claude's own TUI, is Claude's feature under Claude's authentication, consent and device controls. NMSh + passes it through untouched and adds nothing. +- **Per-profile Never / Ask / Always (#334):** not enabled. It may be revisited only after a probe on a real account + shows documented Remote Control for the Managed transport, or Claude documents it. +- NMSh never inspects Claude credentials, never enables remote access because Claude is detected, and never relays + sessions itself. + +## Physical QA still required (not performed) + +- Codex: signed-in `codex app-server` with the adapter: a message, a command approval accepted and declined, a file + change approval, an interrupt mid-command, a failure (for example a usage limit), Safe/NO_COLOR presentation once + wired. +- OpenCode: `opencode serve` on a scratch project, fetch `/doc`, record the event types for the installed version. +- Claude: confirm whether `claude --print --input-format stream-json --output-format stream-json --remote-control` + is accepted, rejected, or ignored on a subscription account, without enabling auto-connect. diff --git a/src/agents/sessions/claudeAdapter.ts b/src/agents/sessions/claudeAdapter.ts index 36f2e4fb..90a3c695 100644 --- a/src/agents/sessions/claudeAdapter.ts +++ b/src/agents/sessions/claudeAdapter.ts @@ -62,6 +62,20 @@ function toolTarget(input: unknown): string | undefined { return undefined; } +/** + * What a permission prompt is about, in full enough that it cannot hide anything: a command shows every line (line + * breaks as ` ⏎ `, a cut says how much is not shown); other tools use their factual target.
