+An agent's hooks say its turn finished whether it is done or asks you
+something ("go ahead?"). **Turn check**, off by default and turned on per
+box in Settings → Agents, tells these apart for Claude Code and Codex: when
+a turn ends normally, berthd sends the turn's last prompt (looking back past
+a long turn's tool calls) and reply from the agent's transcript, and the
+session's title as its objective, to the decision model you pick. Nothing
+is picked for you:
+
+| Provider | Where turns go | Key | Model |
+| --- | --- | --- | --- |
+| **Jev on AI Gateway** | Vercel AI Gateway's evaluate endpoint, prompt training disallowed | Your AI Gateway key | `typesafe-ai/jev` |
+| **OpenAI Decisions** | OpenAI's [Decisions API](https://developers.openai.com/api/docs/guides/decisions) (public beta) | Your OpenAI API key | `gpt-6-luna` |
+| **Laya, your own server** | [Laya](https://huggingface.co/convaiinnovations/laya)'s `laya-serve` (`pip install "laya[serve]"`), or another server that answers Jev's request, at the address you give | None | Optional: `english`, `multilingual` or `typed-decisions`; Laya picks one by itself |
+
+The prompt is capped at 4,000 characters, the reply at its last 12,000, and
+what looks like a secret is taken out of all three first. An agent that
+asks you something, or is blocked, shows as **Needs you**
+(`agent.waiting` with `source: "turncheck"` and the model's `choice`), and
+notifications follow; it still takes prompts as if done, so held prompts
+and other agents' reports are delivered. Unfinished work that needs
+nothing from you is one of two kinds, and neither notifies. **Working**:
+something it started is still running and it acts when that ends (a
+delegated task, a build, a deploy, a test run, or a watcher it started);
+the session stays `finished` with `unfinished: true`. **Parked**: nothing
+runs for it, and it waits on someone else (a reply, another team, a
+vendor) or a later time ("check again in 24 hours", "continue on
+Thursday"); the session stays `finished` with `parked: true` and shows as
+**Idle**. Both are `agent.ready` with `source: "turncheck"` and the
+model's `choice` (`working` or `parked`); both take prompts and end waits
+as done, and stay out of Review, so Done holds only work that is done. A
+dev server or shell left running after the agent is done is not work in
+progress, and anything that waits on you is **Needs you**. Anything else (done, an answer under 65%
+sure, a failed request, no answer in 10 seconds, or you prompting again
+first) leaves it **Done**; no other model is asked.
+
+Settings → Agents, which only a paired laptop can change, keeps a key per
+provider on the box, readable by you alone, and sends each only to its own
+provider; a [secret reference](/guides/secrets) (`op://…`, or `env://NAME`
+from berthd's own environment) is the alternative. Laya gets no key. A Laya
+server on the box itself or on a private address needs that address in

Only `.env`, `.env.development`, `.env.local` and `.env.development.local` in the worktree's folder are read, in that order, a later file winning: never another path, never through a link out of the worktree, at most 256 KB each. They are read as dotenv writes them (comments, `export`, single and double quotes with escapes in double quotes, backticks, values over several lines); `${NAME}`, `${NAME:-fallback}` and `$NAME` are filled in from the other variables of the same files, never from berthd's environment, and nothing is run. The answer is `{ plugin, location, worktree, command: ".env", files, skipped, variables, answer }`: `files` the names that were read; `skipped` the ones that are there and were not, `{ file, reason }` with `reason` one of `outside`, `not_a_file`, `too_large`, `not_text`, `unreadable`; `variables` the matching ones, `{ name, file, sent, reason? }`, where a variable that was not sent says why (`secret` for an `op://` or `env://` reference, `unresolved` for a `${NAME}` the files do not set, `empty`, `too_long`); and `answer` the helper's own answer without its `env` (for `berth-database`, `{ source, connections }` with the ids of the databases it took). No value is in it. Nothing found is a `200` with empty lists, and the helper is still told, so what an earlier look found goes. Nothing the helper answers is put in any environment, and the worktree is not added to the helper's attached services. 409 `helper_off` when the helper is not running (no file is read then), 409 `helper_no_attach` for a helper whose manifest names no `attach` path, 502 `helper_unreachable` when it did not answer in time or answered an error, `not_found` for a location or worktree the box does not know, and `refused` when a `before:helper.attach` hook says no, and for a caller on the box's own socket: only a paired laptop asks. A berthd from before this answers a plain 404, which the laptop agent passes on as `box_outdated`. **With `env`** (`{ "DATABASE_URL": "…" }`, one or more variables), no file is read: the helper is told those variables, which a person gave, with `.manual` as `command`, in place of what it was last told that way, and an empty `env` takes it back. The answer is the same shape with `command: ".manual"`, no `files`, and each variable as `{ name, file: "", sent: true }`. 400 `bad_request` for a name the manifest's `attach_env` does not match, a name that is not a variable's (it is not repeated), an empty or over-long value, or one that names a secret. A value given this way is a secret: it is read from the request's body, handed to the helper, and is in no answer, error, log or event of berthd's, which keeps none of it; the gate's data has `from: ".manual"` and not the variables |
 | `ANY helpers/{plugin}/api/{path}` | The helper's own API, relayed: `{path}`, the query and the body reach it as they were sent, and its answer comes back as it is, a stream included. The request reaches the helper as one from the box itself: its `Host` is the helper's loopback address, and `Origin`, `Referer`, `Cookie` and `Authorization` are removed. 409 `helper_off` when the helper is not running; 502 `helper_unreachable` when it did not answer. One answer does not come back as the helper wrote it: its own 401. On the connection between the laptop and a box a 401 means the box no longer trusts the laptop, so the agent asks the box, and when the box still answers it the helper's refusal comes back as 401 `unauthorized` in the agent's words (a helper that asks for a token refuses a box whose `berthd` is from before it sent one) |
