+# Secrets (sops-nix)
+
+Secrets are encrypted with [sops](https://github.com/getsops/sops) and decrypted
+at activation by [sops-nix](https://github.com/Mic92/sops-nix). Each host decrypts
+with its own SSH host key (converted to an age key in-memory — no separate host
+private key is ever stored on disk).
+
+Tooling (`sops`, `age`, `ssh-to-age`) is available via `nix develop` in this repo,
+and installed system-wide on every machine via `machines/core/sops.nix`.
+
+## Adding a secret to an existing host
+
+```
+nix develop -c sops secrets/<host>.yaml
+```
+
+This opens `$EDITOR` on the decrypted content. Add your key, save, quit — sops
+re-encrypts on write. Then declare it in `machines/<host>/secrets.nix`:
+
+```nix
+sops.secrets.my-secret = {
+  owner = "someuser";   # defaults to root
+  group = "someuser";
+  mode = "0400";
+  restartUnits = [ "foo.service" ];  # if a running service needs to pick it up
+};
+```
+
+Consume it in the owning module as `config.sops.secrets.my-secret.path`
+(resolves to `/run/secrets/my-secret`) — never inline the decrypted value into
+a Nix string, since that copies it into the world-readable `/nix/store`.
+
+Then:
+
+```
+nix build '.#nixosConfigurations.<host>.config.system.build.toplevel'
+sudo nixos-rebuild test --flake '.#<host>'
+# verify, then:
+sudo nixos-rebuild switch --flake '.#<host>'
+```
+
+**The secrets file must be `git add`ed before `nix build`** — untracked files
+are invisible to flake evaluation, and `sops.validateSopsFiles` needs it in the
+Nix store.
+
+## Adding a new host
+
+1. On the new host: `ssh-to-age < /etc/ssh/ssh_host_ed25519_key.pub` to get its
+   age public key.
+2. In `.sops.yaml`: add a `&host_<name>` anchor with that key, and a
+   `creation_rules` entry for `secrets/<name>.yaml` including both the new
+   host key and `*admin_finn`.
+3. Create `machines/<name>/secrets.nix`, add it to that machine's
+   `configuration.nix` imports.
+4. If the host needs to read an existing shared file, run
+   `sops updatekeys secrets/<file>.yaml` after step 2 so it's re-encrypted to
+   include the new recipient.
+
+## Rotating keys
+
+```
+# after editing .sops.yaml (new/removed recipient):
+nix develop -c sops updatekeys secrets/<file>.yaml
+```
+
+for every file the change affects. `updatekeys` requires you to already be
+able to decrypt the file — this is why `*admin_finn` is a recipient on every
+rule, as the standing fallback.
+
+Reinstalling a host regenerates its SSH host key, which changes its age
+identity. Any file previously encrypted to that host must be `updatekeys`'d
+with the new key, or the host's next activation fails to decrypt.
+
+## Where private keys live
+
+- **Operator** (you): `~/.config/sops/age/keys.txt` — sops' default lookup
+  path, so `SOPS_AGE_KEY_FILE` never needs to be set. Never committed. Back
+  this up out-of-band (password manager, offline copy) — if it's lost, only
+  the surviving host keys can still decrypt their own files, and any file that
+  was only ever readable by an operator-only rule becomes permanently
+  unreadable.
+- **Hosts**: `/etc/ssh/ssh_host_ed25519_key` — already managed by NixOS,
+  converted to age in-memory at activation time. Nothing extra to back up.
+
+## Layout
+
+```
+.sops.yaml              # age recipients + creation rules (which keys can decrypt which files)
+secrets/<host>.yaml      # per-host encrypted secrets (default sopsFile for that host)
+machines/core/sops.nix   # applied to every machine: decryption config, sops/age/ssh-to-age on PATH
+machines/<host>/secrets.nix   # per-host: which secrets exist, owner/group/mode

+# Homepage Widgets Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a `my.homepage.widgets` NixOS option so widgets can be declared in the homepage module and contributed from other modules, mirroring how `my.homepage.services` works today.
+
+**Architecture:** Add a `my.homepage.widgets` option (typed `listOf attrs` since widget shapes vary by type) to the homepage module, import a `manual-widgets.nix` for ad-hoc definitions, merge both and pass to `services.homepage-dashboard.widgets`. Add starter widgets in `machines/jupiter/environments.nix` to confirm the wiring works end-to-end.
+
+**Tech Stack:** Nix, NixOS module system, gethomepage.dev (`services.homepage-dashboard`)
+
+---
+
+## File Map
+
+| Action | File | Responsibility |
+|--------|------|----------------|
+| Modify | `modules/environments/homepage/default.nix` | Add `my.homepage.widgets` option + wire to dashboard |
+| Create | `modules/environments/homepage/manual-widgets.nix` | Empty list for ad-hoc widgets (parallel to `manual-services.nix`) |
+| Modify | `machines/jupiter/environments.nix` | Declare starter widgets to verify the feature end-to-end |
+
+---
+
+### Task 1: Add `my.homepage.widgets` option to the homepage module
+
+**Files:**
+- Modify: `modules/environments/homepage/default.nix`
+- Create: `modules/environments/homepage/manual-widgets.nix`
+
+- [ ] **Step 1: Create `manual-widgets.nix`** — empty list, same pattern as `manual-services.nix`
+
+```nix
+# modules/environments/homepage/manual-widgets.nix
+[ ]
+```
+
+- [ ] **Step 2: Add `manualWidgets` import in the `let` block of `default.nix`**
+
+Current `let` block (lines 7–42) ends with `homepageServices`. Add one line after `manualServices`:
+
+```nix
+  manualServices = import ./manual-services.nix;
+  manualWidgets = import ./manual-widgets.nix;
+```
+
+- [ ] **Step 3: Add the `my.homepage.widgets` option**
+
+After the closing brace of `options.my.homepage.services` (line 80), add:
+
+```nix
+  options.my.homepage.widgets = with lib; mkOption {
+    type = types.listOf types.attrs;
+    default = [ ];
+    description = "Widget definitions passed directly to services.homepage-dashboard.widgets. Each entry is an attrset like { resources = { cpu = true; memory = true; }; }.";
+  };
+```
+
+- [ ] **Step 4: Wire widgets to the dashboard in the `config` block**
+
+The `config` block currently sets `services = homepageServices ++ manualServices;`. Add `widgets`:
+
+```nix
+  config = lib.mkIf cfg.enable {
+    services.homepage-dashboard = {
+      enable = true;
+      listenPort = dashboardPort;
+      allowedHosts = "${dashboardHost}:${toString dashboardPort},localhost:${toString dashboardPort},127.0.0.1:${toString dashboardPort},jupiter.solar.internal:${toString dashboardPort}";
+      bookmarks = import ./bookmarks.nix;
+      services = homepageServices ++ manualServices;
+      widgets = config.my.homepage.widgets ++ manualWidgets;
+    };
+    # ... rest of config unchanged
+  };
+```
+
+- [ ] **Step 5: Build to check for eval errors (no switch yet)**
+
+```bash
+nixos-rebuild build --flake /Users/finnmarkwitz/development/nixos#jupiter 2>&1 | tail -20
+```
+
+Expected: build succeeds with no errors (widgets list is empty, so no visible change yet).
+
+- [ ] **Step 6: Commit**
+
+```bash
+cd /Users/finnmarkwitz/development/nixos
+git add modules/environments/homepage/default.nix modules/environments/homepage/manual-widgets.nix
+git commit -m "feat: add my.homepage.widgets option to homepage module"
+```
+
+---
+
+### Task 2: Add starter widgets in `environments.nix`
+
+**Files:**
+- Modify: `machines/jupiter/environments.nix`
+
+- [ ] **Step 1: Add `my.homepage.widgets` to `environments.nix`**
+
+Add the following after the `my.profiles` block (e.g. after line 39, before the `my.hardware` block):
+
+```nix
+  my.homepage.widgets = [
+    {
+      search = {
+        provider = "google";
+        target = "_blank";
+      };
+    }
+    {
+      resources = {
+        cpu = true;
+        memory = true;
+        disk = "/";
+        cacheInterval = 5000;
+      };
+    }
+    {
+      datetime = {
+        text_size = "xl";
+        format = {
+          timeStyle = "short";
+          dateStyle = "short";
+          hour12 = false;
+        };
+      };
+    }
+  ];
+```
+
+- [ ] **Step 2: Build to confirm eval**
+
+```bash
+nixos-rebuild build --flake /Users/finnmarkwitz/development/nixos#jupiter 2>&1 | tail -20
+```
+
+Expected: build succeeds.
+
+- [ ] **Step 3: Switch and verify visually**
+
+```bash
+sudo nixos-rebuild switch --flake /Users/finnmarkwitz/development/nixos#jupiter
+```
+
+Open `http://jupiter.solar.internal:8082` (or `http://localhost:8082`) in a browser.
+
+Expected: search bar, CPU/memory/disk resource monitor, and date/time widget appear at the top of the dashboard.
+
+- [ ] **Step 4: Commit**
+
+```bash
+cd /Users/finnmarkwitz/development/nixos
+git add machines/jupiter/environments.nix
+git commit -m "feat: add starter homepage widgets (search, resources, datetime)"
+```
+
+---
+
+## Verification Checklist
+
+- [ ] `nixos-rebuild build` passes with no eval errors
+- [ ] Dashboard at `:8082` shows widgets at top of page
+- [ ] Existing services and bookmarks are unchanged
+- [ ] Other modules can now contribute widgets via `my.homepage.widgets = [ ... ];` in their `config` block

+# Hermes Agent on mibook Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+>
+> **Note on nature:** Task 1 is repo-only work verifiable with `nix build` — no runtime tests exist for declarative config, matching this repo's existing convention (see the Immich plan). Tasks 2–5 are an **operator-run runbook**, not agent-automatable: Task 2 needs an interactive `claude setup-token` OAuth login, an Anthropic billing console check, and a Telegram BotFather chat; Task 3 requires typing real secret material into the `$EDITOR` sops opens; Task 4 runs `nixos-rebuild` on mibook, the operator's live daily-driver desktop. **Never paste secret values (tokens, passwords) into an agent session or chat** — Task 3 has the operator type them directly into the editor sops opens. Present Tasks 2–5 for the operator to run and confirm; do not attempt to execute them from an agent session.
+
+**Goal:** Run Hermes Agent as a hardened NixOS systemd service on mibook, reachable via Telegram and Email, authenticated to Anthropic via a Claude subscription (`claude setup-token`) rather than a pay-per-token API key.
+
+**Architecture:** A standard `my.profiles.hermes-agent` module wraps the upstream `services.hermes-agent` module (from `NousResearch/hermes-agent`'s `nixosModules.default`), imported from inside the profile module itself so both machines can evaluate it — only mibook ever turns it on (see Task 1 Step 3). Credentials (Anthropic token, Telegram bot token, email creds, both `*_ALLOWED_USERS` access-control keys) live in one sops secret (`hermes-env`) consumed via `environmentFiles`. No network exposure — Telegram long-polling and Email IMAP/SMTP are both outbound-initiated from mibook.
+
+**Tech Stack:** NixOS (flake-parts), sops-nix, upstream `hermes-agent` flake (Tier 2/best-effort Nix support), Anthropic Claude (subscription auth).
+
+**Spec:** `docs/superpowers/specs/2026-09-08-hermes-agent-nixos-design.md`
+
+## Global Constraints
+
+- Machine: **mibook** only. Do not enable on jupiter.
+- Module source: official `github:NousResearch/hermes-agent` (`nixosModules.default`). Not the community `0xrsydn/nix-hermes-agent` wrapper.
+- Auth: `claude setup-token` output goes into `ANTHROPIC_TOKEN` in the `hermes-env` secret — **not** `ANTHROPIC_API_KEY`. Confirmed supported by the locked revision's source (Task 4 Step 2); no longer conditional.
+- Billing dependency: the setup-token/OAuth path only draws from **Claude Max "extra usage credits"** — confirm this pool is funded before Task 2's token generation, or auth will fail even with a valid token.
+- Module wiring: the upstream `hermes-agent.nixosModules.default` import lives **inside** `modules/environments/hermes-agent/default.nix` (via the `inputs` module arg), never in `machines/configuration.nix`'s per-machine module lists — wiring it there breaks jupiter's evaluation even with the profile disabled (see Task 1 Step 3's correction).
+- Access control: `TELEGRAM_ALLOWED_USERS` and `EMAIL_ALLOWED_USERS` are required in the `hermes-env` secret, not optional — see Task 2 Steps 3–4.
+- Secret persistence: credentials end up in plaintext at `/var/lib/hermes/.hermes/.env` (mode 0640), not sops-nix's `/run/secrets` tmpfs — rollback (Task 5 Step 3) accounts for this.
+- Secret: one sops secret named `hermes-env`, a full env-file blob (matches `environmentFiles` — list of paths, not a single-value secret).
+- No network exposure: do not touch `modules/services/webserver` or open any inbound port. Telegram + Email are both outbound-only.
+- Platforms: Telegram + Email only, first pass. No Discord/Slack/etc.
+- Rebuild command: `sudo nixos-rebuild switch --flake '.#mibook'` (use `nixos-rebuild test` first, per Task 4).
+- Build-check command: `nix build '.#nixosConfigurations.mibook.config.system.build.toplevel'`.
+- Format Nix with `nixfmt-rfc-style` before committing.
+- Secret material never enters an agent session, chat, or the git history in plaintext — only via `sops secrets/mibook.yaml` and `$EDITOR`.
+- Base branch: `feat/sops-nix` (already pushed; do not merge or rebase it as part of this work).
+
+---
+
+## File Structure
+
+- **Modify** `flake.nix` — add the `hermes-agent` flake input.
+- **Not modified** `machines/configuration.nix` — Task 1 originally wired the upstream module import here (mibook-only); this broke jupiter's evaluation and was corrected to import from inside the profile module instead. See Task 1 Step 3.
+- **Create** `modules/environments/hermes-agent/default.nix` — the `my.profiles.hermes-agent` module (single responsibility: declare Hermes Agent).
+- **Modify** `modules/environments/default.nix` — add `./hermes-agent` to the import list.
+- **Modify** `machines/mibook/environments.nix` — set `hermes-agent.enable = true`.
+- **Modify** `machines/mibook/secrets.nix` — replace the `placeholder` secret with `hermes-env`.
+- **Modify (encrypted, operator-only)** `secrets/mibook.yaml` — real credential values, never touched by an agent.
+
+No other files change.
+
+---
+
+### Task 1: Wire up the module (flake input, profile module, secret declaration)
+
+**Files:**
+- Modify: `flake.nix`
+- Create: `modules/environments/hermes-agent/default.nix`
+- Modify: `modules/environments/default.nix`
+- Modify: `machines/mibook/environments.nix`
+- Modify: `machines/mibook/secrets.nix`
+- **Not modified:** `machines/configuration.nix` — see Step 3's correction.
+
+**Interfaces:**
+- Produces: NixOS option `my.profiles.hermes-agent.enable` (bool). When true, configures `services.hermes-agent` with `environmentFiles = [ config.sops.secrets."hermes-env".path ]` and grants `finn` the `hermes` group. Declares `sops.secrets.hermes-env` (owner/group `hermes`, path resolves to `/run/secrets/hermes-env` at runtime — but note the *service* re-copies it to `/var/lib/hermes/.hermes/.env`, per the spec's persistence note).
+- Consumes: `hermes-agent.nixosModules.default` from the new flake input, imported directly inside the profile module via `self.inputs` (the `self` module arg, from `specialArgs` — see Step 3 and Step 5's note on why not the `inputs` module arg) — not through `machines/configuration.nix`; existing `sops.secrets.<name>` mechanism from `machines/core/sops.nix` (already applied to every machine, unaffected by this task).
+
+- [ ] **Step 1: Add the flake input**
+
+In `flake.nix`, inside `inputs = { ... }`, add after the `sops-nix` block:
+
+```nix
+    hermes-agent = {
+      url = "github:NousResearch/hermes-agent";
+      inputs.nixpkgs.follows = "nixpkgs";
+    };
+```
+
+- [ ] **Step 2: Lock the new input**
+
+Run: `nix flake lock`
+Expected: `flake.lock` gains a `hermes-agent` entry (and its transitive inputs). No other entries change.
+
+- [ ] **Step 3: Do NOT wire the module import through `machines/configuration.nix`**
+
+**Correction (found during final whole-plan review, 2026-09-08):** an
+earlier version of this step added `hermes-agent` to the
+`inherit (self.inputs) ...` destructure and `hermes-agent.nixosModules.default`
+to mibook's `modules` list in `machines/configuration.nix`. That broke
+`nixosConfigurations.jupiter` evaluation — confirmed by direct `nix eval`.
+`modules/environments/default.nix` (Step 6) is machine-agnostic, so jupiter
+loads the profile module too; NixOS's module system errors on a definition
+for an undeclared option **regardless of `lib.mkIf`'s condition**. Since
+jupiter never imported `hermes-agent.nixosModules.default`, it never
+declared `services.hermes-agent` as an option at all, so even the disabled
+(`mkIf false`) config definition in Step 5 crashed evaluation.
+
+Skip this step — do not touch `machines/configuration.nix` at all. The fix
+lives in Step 5: the upstream module is imported from inside the profile
+module itself, which works correctly on both machines (declares the option
+everywhere, only ever turns it on where `my.profiles.hermes-agent.enable = true`).
+
+- [ ] **Step 4: Read a reference module to match repo style**
+
+Read `modules/environments/immich/default.nix` (same shape: `cfg`, `lib.mkIf`, single-purpose options block). Match its formatting.
+
+- [ ] **Step 5: Create the profile module**
+
+Create `modules/environments/hermes-agent/default.nix`:
+
+```nix
+# Hermes Agent — Telegram + Email messaging gateway (Claude subscription auth)
+{
+  config,
+  lib,
+  pkgs,
+  self,
+  ...
+}:
+let
+  cfg = config.my.profiles.hermes-agent;
+in
+{
+  imports = [ self.inputs.hermes-agent.nixosModules.default ];
+
+  options.my.profiles.hermes-agent.enable =
+    lib.mkEnableOption "Hermes Agent (Telegram + Email gateway)";
+
+  config = lib.mkIf cfg.enable {
+    services.hermes-agent = {
+      enable = true;
+      # Deliberate pin, matches the approved design — bump on purpose, not by drift.
+      settings.model.default = "anthropic/claude-sonnet-4-5";
+      environmentFiles = [ config.sops.secrets."hermes-env".path ];
+      addToSystemPackages = true;
+    };
+
+    # addToSystemPackages only puts `hermes` on $PATH; using it needs group
+    # access to /var/lib/hermes/.hermes (mode 2770 hermes:hermes). finn is
+    # this machine's one human user and already knows hermes-env's contents
+    # (typed them into sops directly), so this is not new exposure.
+    users.users.finn.extraGroups = [ "hermes" ];
+  };
+}
+```
+
+**Use `self`, not `inputs`, in the `imports` line.** `inputs` is supplied
+via `_module.args.inputs = self.inputs;`, set inside a config block —  but
+NixOS resolves a module's `imports` before `_module.args` assignments
+merge, so anything referenced inside `imports` must come from
+`specialArgs` (fixed up front) instead. `self` is threaded via
+`specialArgs = { inherit self; };` in `machines/configuration.nix` and is
+available at import-time; `inputs` is not. Using `inputs` here reproduces
+`infinite recursion encountered` — confirmed by testing it directly, not
+theoretical. `self.inputs.hermes-agent` is the same flake input either way.
+
+- [ ] **Step 6: Register the module in the environments import list**
+
+In `modules/environments/default.nix`, add `./hermes-agent` after `./immich`:
+
+```nix
+    ./immich
+    ./hermes-agent
+  ];
+}
+```
+
+- [ ] **Step 7: Enable it on mibook**
+
+In `machines/mibook/environments.nix`, inside the `my.profiles = { ... }` block, add:
+
+```nix
+    hermes-agent.enable = true;
+```
+
+- [ ] **Step 8: Replace the placeholder secret declaration**
+
+In `machines/mibook/secrets.nix`, replace the whole file body:
+
+```nix
+# Secrets decrypted on mibook. sopsFile defaults to secrets/mibook.yaml
+# via machines/core/sops.nix.
+{ ... }:
+{
+  sops.secrets.hermes-env = {
+    owner = "hermes";
+    group = "hermes";
+    mode = "0400";
+    restartUnits = [ "hermes-agent.service" ]; # confirmed against the locked revision's generated unit
+  };
+}
+```
+
+This removes the `placeholder` secret declared here — it was an explicit throwaway (comment: "Safe to delete once a real secret is in place"). Its entry in the encrypted `secrets/mibook.yaml` content itself is cleaned up by the operator in Task 3, not here.
+
+- [ ] **Step 9: Format**
+
+Run: `nixfmt-rfc-style modules/environments/hermes-agent/default.nix machines/mibook/secrets.nix machines/mibook/environments.nix flake.nix`
+
+- [ ] **Step 10: Build-check (this is the "test", with a known-expected failure until Task 3)**
+
+Run: `nix build '.#nixosConfigurations.mibook.config.system.build.toplevel'`
+**Correction (found during Task 1 implementation, 2026-09-08):** this does **not** build cleanly yet, and that's expected — `sops.validateSopsFiles = true` (set repo-wide in `machines/core/sops.nix`) makes secret-key existence a **build-time** dependency of `config.system.build.toplevel` (via a `manifest.json.drv` step), not an activation-time check as originally assumed here. Since `secrets/mibook.yaml` still only has the `placeholder` key at this point in the plan (Task 3 adds `hermes-env`), the build correctly fails with:
+```
+> .../sops-install-secrets: manifest is not valid: secret hermes-env in .../mibook.yaml is not valid: the key 'hermes-env' cannot be found
+```
+Do **not** treat this as a wiring defect, and do not weaken `sops.validateSopsFiles` to work around it — that's a repo-wide safety invariant, not this task's to change. Instead, confirm the wiring is correct by two other means: `nix build ... --dry-run` (should complete with no eval errors and the full derivation list) and Step 11 below. A fully green (non-dry-run) `nix build` of the toplevel is only reachable after Task 3 populates the real secret — treat that as the actual end-to-end checkpoint, revisited in Task 4 Step 1.
+If `--dry-run` itself fails on an unknown `services.hermes-agent.*` option, reconcile against the actual module: the error will name the bad option; cross-check against `website/docs/getting-started/nix-setup.md` in the `NousResearch/hermes-agent` repo at the locked revision.
+
+- [ ] **Step 11: Build-check jupiter too — this is the regression gate**
+
+Run: `nix eval '.#nixosConfigurations.jupiter.config.system.build.toplevel.drvPath'`
+Expected: succeeds, printing a `.drv` path. **Any change under `modules/` is a two-machine change even when it's "for one host"** — `modules/environments/default.nix` (Step 6) is loaded by every machine, so a mistake here can break jupiter's eval even though jupiter never enables this profile. This is exactly the failure Step 3's correction fixes; this step is what catches it if it ever regresses.
+
+- [ ] **Step 12: Confirm the option evaluates on mibook**
+
+Run: `nix eval '.#nixosConfigurations.mibook.config.services.hermes-agent.enable'`
+Expected: `true`
+
+- [ ] **Step 13: Commit**
+
+```bash
+git add flake.nix flake.lock modules/environments/hermes-agent/default.nix modules/environments/default.nix machines/mibook/environments.nix machines/mibook/secrets.nix
+git commit -m "feat(mibook): add Hermes Agent profile module"
+```
+
+**Post-review note, 2026-09-08:** Task 1 was originally committed as
+`731678e` with the jupiter-breaking bug Step 3 describes and fixes — the
+upstream module was wired through `machines/configuration.nix`'s
+mibook-only module list instead of imported inside the profile module. The
+final whole-plan review caught it (jupiter's `nixosConfigurations` stopped
+evaluating, breaking the repo's sole CI job even though jupiter never
+enables this profile). It was corrected in a follow-up commit on the same
+branch — run `git log --oneline -- modules/environments/hermes-agent/ machines/configuration.nix`
+if you need both commit hashes. The steps above already reflect the
+corrected, final approach — executing this plan from scratch would never
+hit the bug.
+
+---
+
+### Task 2: Gather credentials (operator-run, not agent-automatable)
+
+**Files:** none. All values are held by the operator for Task 3 — do not write them into any file an agent can read, and do not paste them into a chat session.
+
+**Interfaces:**
+- Produces: an Anthropic setup-token, a Telegram bot token, and email (IMAP/SMTP) credentials — ready to type into `$EDITOR` in Task 3.
+
+- [ ] **Step 1: Confirm the billing pool is funded**
+
+In the Anthropic console, confirm the Claude Max plan has **extra usage credits purchased**. The `claude setup-token` auth path bills against this pool only — it does not draw from the base Max allowance, and Claude Pro cannot use this path at all. If this isn't funded, stop here and decide whether to fund it or fall back to a plain `ANTHROPIC_API_KEY` (see Global Constraints).
+
+- [ ] **Step 2: Generate the setup-token**
+
+On mibook, run: `claude setup-token`
+This opens an interactive OAuth flow. On completion it prints a long-lived token. Copy it somewhere only you control (e.g. your password manager) — you'll type it into `sops` in Task 3, not into this session.
+
+- [ ] **Step 3: Create the Telegram bot, and get your own user ID**
+
+In Telegram, message `@BotFather`, run `/newbot`, follow the prompts. Copy the resulting bot token (format `123456:ABC-...`). Also get your own numeric Telegram user ID (e.g. via `@userinfobot`) — Task 3 needs it for `TELEGRAM_ALLOWED_USERS`. Telegram defaults to open DM pairing (any stranger who messages the bot gets a pairing code and can request approval); without this allowlist, that's the default posture, not a hardened one.
+
+- [ ] **Step 4: Gather email credentials**
+
+Decide which mailbox Hermes Agent should use, and get its IMAP/SMTP host, username, and password (or app-specific password if the provider requires one, e.g. Gmail). The exact env var names (confirmed against the locked `hermes-agent` revision, not guessed) are `EMAIL_ADDRESS`, `EMAIL_PASSWORD`, `EMAIL_IMAP_HOST`, `EMAIL_SMTP_HOST`, plus optional `EMAIL_IMAP_PORT` (default 993) / `EMAIL_SMTP_PORT` (default 587) if your provider differs — see `website/docs/user-guide/messaging/email.md` and `website/docs/reference/environment-variables.md` in the `NousResearch/hermes-agent` repo for more detail. Also decide `EMAIL_ALLOWED_USERS` (your own sending address) — without it, mail from unrecognized senders is **silently ignored** with no log line, which Task 4 Step 4 depends on knowing.
+
+---
+
+### Task 3: Populate the secret (operator-run, secret material)
+
+**Files:**
+- Modify (encrypted): `secrets/mibook.yaml`
+
+**Interfaces:**
+- Consumes: the three credentials gathered in Task 2, and the `hermes-env` declaration from Task 1.
+- Produces: a decryptable `hermes-env` entry that Task 1's `environmentFiles` reference resolves at activation.
+
+- [ ] **Step 1: Open the encrypted file**
+
+Run: `nix develop -c sops secrets/mibook.yaml`
+This decrypts and opens `$EDITOR` on the plaintext.
+
+- [ ] **Step 2: Remove the placeholder key, add `hermes-env`**
+
+Delete the `placeholder: ...` entry (Task 1 already removed its Nix declaration; this removes the matching content). Add:
+
+```yaml
+hermes-env: |
+    ANTHROPIC_TOKEN=<paste the claude setup-token output>
+    TELEGRAM_BOT_TOKEN=<paste the BotFather token>
+    TELEGRAM_ALLOWED_USERS=<your numeric Telegram user id, from Task 2 Step 3>
+    EMAIL_ADDRESS=<mailbox address>
+    EMAIL_PASSWORD=<password or app-password>
+    EMAIL_IMAP_HOST=<imap host>
+    EMAIL_SMTP_HOST=<smtp host>
+    EMAIL_ALLOWED_USERS=<your own sending address, from Task 2 Step 4>
+```
+
+(Exact YAML block-scalar syntax per whatever your `$EDITOR` shows — sops re-encrypts on save regardless of formatting, as long as it's valid YAML. Both `*_ALLOWED_USERS` keys are access control, not optional — see Task 2 Steps 3–4 for why.)
+
+- [ ] **Step 3: Save and let sops re-encrypt**
+
+Save and quit `$EDITOR`. Run: `git diff --stat secrets/mibook.yaml`
+Expected: the file shows as changed (still fully encrypted — confirm by `git diff secrets/mibook.yaml | head` and seeing sops's `ENC[...]` ciphertext, never plaintext).
+
+- [ ] **Step 4: Stage it**
+
+Run: `git add secrets/mibook.yaml`
+Required before the next `nix build` — untracked sops files are invisible to flake evaluation (repo rule, `docs/secrets.md`).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git commit -m "feat(mibook): populate Hermes Agent credentials"
+```
+
+---
+
+### Task 4: Deploy and verify (operator-run, on mibook)
+
+**Files:** none in repo. Run all commands on mibook.
+
+**Interfaces:**
+- Consumes: the built config from Task 1, the secret from Task 3.
+- Produces: a running, verified `hermes-agent.service` reachable via Telegram and Email.
+
+- [ ] **Step 1: Test-activate without persisting**
+
+Run: `sudo nixos-rebuild test --flake '.#mibook'`
+Expected: activates without reboot-persisting. If it fails at secret decryption ("hermes-env not found in sops file"), Task 3 wasn't saved/staged correctly — redo Task 3.
+
+- [ ] **Step 2: Watch the service start**
+
+`hermes-agent.service` is the confirmed unit name (verified against the locked revision's generated unit, not a guess). Run: `journalctl -u hermes-agent.service -f`
+Expected: starts, reads the env file (lands at `/var/lib/hermes/.hermes/.env` — see spec Part 2), and does **not** crash-loop on auth. `ANTHROPIC_TOKEN` is confirmed supported by the module's credential resolver, so an auth failure here points at the token itself (expired, or the extra-credits pool from Task 2 Step 1 isn't actually funded) rather than the module rejecting the variable name.
+
+- [ ] **Step 3: Verify Telegram connects**
+
+Send your bot a message from Telegram. Expected: it responds (confirms both the bot token and the LLM auth work end-to-end).
+
+- [ ] **Step 4: Verify Email connects**
+
+Send a test email to the configured mailbox. Expected: Hermes Agent picks it up (check `journalctl -u hermes-agent.service` for an inbound-message log line) and can send a reply.
+
+- [ ] **Step 5: Persist across reboot**
+
+Run: `sudo nixos-rebuild switch --flake '.#mibook'`
+Expected: same running state as Step 1–4, now persisted.
+
+---
+
+### Task 5: Sign-off (operator-run)
+
+**Files:** none in repo beyond what Tasks 1 and 3 already committed.
+
+**Interfaces:**
+- Consumes: a verified running instance (Task 4).
+
+- [ ] **Step 1: Open a PR**
+
+`feat/sops-nix` is already pushed to `origin` but not merged; this work sits on top of it. Push this branch (or continue on `feat/sops-nix` directly, per your preference) and open a PR per the repo's usual Gitea workflow. Note in the PR description that it depends on `feat/sops-nix` landing first (or is stacked on it).
+
+- [ ] **Step 2: Confidence window**
+
+Use it for a few days — send yourself Telegram/Email messages periodically, including after mibook has slept and woken up, to see how the accepted availability gap actually behaves in practice.
+
+- [ ] **Step 3: Rollback (if needed)**
+
+`my.profiles.hermes-agent.enable = false` in `machines/mibook/environments.nix`, `sudo nixos-rebuild switch --flake '.#mibook'` stops the service — but the plaintext credential file survives on disk (see spec's Rollback section for why). Also run `sudo rm -rf /var/lib/hermes` and revoke the Telegram bot token via `@BotFather` → `/revoke`. No data migration is involved, so this is still cheap, just not a single command.
+

+
+## Self-Review
+
+**Spec coverage:**
+- Host mibook, not jupiter → Global Constraints + File Structure. ✓
+- NixOS native module, official upstream source → Task 1. ✓
+- Home Manager rejected → not present anywhere (correctly absent, matches "deliberately deferred" reasoning — no task references it). ✓
+- `claude setup-token` → `ANTHROPIC_TOKEN`, Max extra-credits caveat → Task 2 Steps 1–2, Task 4 Step 2, Global Constraints. ✓
+- `hermes-env` single env-file secret → Task 1 Step 8, Task 3. ✓
+- No sops prerequisite (mibook already registered) → confirmed by reusing existing `machines/mibook/secrets.nix` rather than any `.sops.yaml`/Phase-9-style bootstrapping. ✓
+- No network exposure → Global Constraints; no task touches `modules/services/webserver`. ✓
+- Telegram + Email only → Task 2 Steps 3–4, Task 4 Steps 3–4. ✓
+- Rollback path → Task 5 Step 3. ✓
+- Deferred (other platforms, availability-gap workarounds, public exposure) → correctly absent. ✓
+
+**Placeholder scan:** No bare TBD/TODO. The bracketed values (`<paste the claude setup-token output>`, etc.) are operator-supplied secret material by design — Task 2 explicitly produces them, Task 3 explicitly consumes them; they're never meant to be concrete in this document since they're credentials, not code.
+
+**Type consistency:** `my.profiles.hermes-agent.enable`, `services.hermes-agent.*`, and the `hermes-env` secret name are used identically across Tasks 1, 3, and 4. The `hermes-agent.service` unit name and `ANTHROPIC_TOKEN` var are confirmed (not guessed) consistently in both Task 1's declaration and Task 4's verification.
+
+**Post-final-review addendum (2026-09-08):** the final whole-plan review found the module-wiring bug described in Task 1 Step 3, plus three access/persistence gaps now folded into Global Constraints, Task 2 Steps 3–4, Task 3's template, and Task 5 Step 3's rollback (TELEGRAM_ALLOWED_USERS/EMAIL_ALLOWED_USERS required; secrets persist to `/var/lib/hermes/.hermes/.env`, not `/run/secrets`; `hermes` CLI needs `finn` in the `hermes` group to be usable). All four are corrected in place above, not left as separate addenda, so the plan reads as a single coherent document rather than a stack of patches.

+# Hermes Agent on mibook
+
+**Date:** 2026-09-08
+**Machine:** mibook (laptop, KDE desktop, current daily driver)
+**Status:** Design approved, pending implementation plan
+**Base branch:** `feat/sops-nix` (pushed to `origin`, not yet merged to `main`)
+
+## Goal
+
+Deploy [NousResearch/hermes-agent](https://github.com/NousResearch/hermes-agent)
+as a NixOS-native systemd service on mibook, reachable via Telegram and Email,
+using an Anthropic Claude subscription (`claude setup-token`) rather than a
+pay-per-token API key. Design + implementation plan only — no execution in
+this round; a later session applies the plan.
+
+## Decisions
+
+| Topic | Decision |
+|-------|----------|
+| Host | mibook, not jupiter. Availability gap (laptop sleeps/lid-closes) is accepted, not engineered around |
+| Use case | Messaging gateway (Telegram + Email), not CLI-only |
+| Deployment mode | NixOS native module (`services.hermes-agent.*` from upstream `nixosModules.default`), wrapped in `my.profiles.hermes-agent`. Home Manager was considered and rejected — not wired into this flake anywhere; adding it for one service is a new framework dependency, not proportionate |
+| Module source | Official `github:NousResearch/hermes-agent`, not the community `0xrsydn/nix-hermes-agent` wrapper |
+| Nix support tier | Docs explicitly call Nix/NixOS "Tier 2, best-effort" — Docker/FHS is upstream's primary supported path. Accepted tradeoff, not a blocker |
+| LLM provider auth | Anthropic via `claude setup-token` (long-lived, headless-friendly token) → `ANTHROPIC_TOKEN`, not `ANTHROPIC_API_KEY` |
+| Billing caveat | Setup-token/OAuth path only draws from a **Claude Max "extra usage credits"** pool, never the base Max allowance. Claude Pro cannot use this path at all. User intends to use `claude setup-token`; not independently re-verified that extra credits are purchased — confirm in Anthropic console before/during implementation |
+| Secrets | One sops secret, `hermes-env`, containing a full env-file blob (matches the module's `environmentFiles` list-of-paths interface — not a single-value secret) |
+| sops prerequisite | **None.** mibook is already a registered sops recipient (`host_mibook` in `.sops.yaml`, `secrets/mibook.yaml` exists, proven via a live `nixos-rebuild switch` in the sops-nix work). No "Phase 9"-style bootstrapping needed — that deferred work is about *jupiter*, irrelevant now that mibook is the target |
+| Network exposure | None. Telegram (long-polling) and Email (IMAP/SMTP) are both outbound-initiated from mibook. No Caddy/webserver module changes, no public endpoint |
+| Messaging platforms | Telegram + Email only, first pass. Hermes Agent supports 27+ platforms total (Discord, Slack, WhatsApp, Matrix, etc.) — others deliberately out of scope, same pattern applies later if wanted |
+
+### Deliberately deferred (YAGNI)
+- Any workaround for mibook's availability gap (cloud relay, wake scheduling, HA failover to jupiter)
+- Discord, Slack, or any other messaging platform beyond Telegram + Email
+- Public/internet exposure of any kind
+- Merging or rebasing `feat/sops-nix` — this design builds on top of it as-is
+
+## Part 1 — The module
+
+New flake input in `flake.nix`, following the exact shape `sops-nix` already
+uses:
+
+```nix
+hermes-agent = {
+  url = "github:NousResearch/hermes-agent";
+  inputs.nixpkgs.follows = "nixpkgs";
+};
+```
+
+Import the upstream module **from inside the profile module itself**, via
+`imports = [ self.inputs.hermes-agent.nixosModules.default ];` — using
+`self` (available via `specialArgs = { inherit self; };` in
+`machines/configuration.nix`), not the `inputs` module arg. **Correction
+(found during implementation, 2026-09-08):** `inputs` is supplied via
+`_module.args.inputs = self.inputs;`, set inside a config block — but
+NixOS resolves a module's `imports` list before `_module.args` assignments
+merge, so anything referenced inside `imports` must come from
+`specialArgs` (fixed up front) instead. Using `inputs` here reproduces
+`infinite recursion encountered`; `self.inputs.hermes-agent` is the same
+flake input, reached the way that actually works. Separately, this is
+deliberately *not* wired through `machines/configuration.nix`'s per-machine
+module lists. NixOS's module system errors on a definition for an
+undeclared option regardless of `lib.mkIf`'s condition — so declaring
+`services.hermes-agent` only on mibook while jupiter still loads the
+profile module (because `modules/environments/default.nix` is
+machine-agnostic) breaks jupiter's evaluation outright, even with the
+profile disabled there. Importing the upstream module unconditionally, and
+gating only `config` behind `lib.mkIf cfg.enable`, is what actually
+respects "mibook only, not jupiter": the option exists everywhere
+(harmless), but only ever turns on where `enable = true`.
+
+New file `modules/environments/hermes-agent/default.nix` following the
+repo's standard profile pattern:
+
+```nix
+# Hermes Agent — Telegram + Email messaging gateway (Claude subscription auth)
+{
+  config,
+  lib,
+  pkgs,
+  self,
+  ...
+}:
+let
+  cfg = config.my.profiles.hermes-agent;
+in
+{
+  imports = [ self.inputs.hermes-agent.nixosModules.default ];
+
+  options.my.profiles.hermes-agent.enable =
+    lib.mkEnableOption "Hermes Agent (Telegram + Email gateway)";
+
+  config = lib.mkIf cfg.enable {
+    services.hermes-agent = {
+      enable = true;
+      settings.model.default = "anthropic/claude-sonnet-4-5"; # deliberate pin, see Open risks
+      environmentFiles = [ config.sops.secrets."hermes-env".path ];
+      addToSystemPackages = true;
+    };
+
+    # addToSystemPackages only puts `hermes` on $PATH; using it needs group
+    # access to /var/lib/hermes/.hermes (mode 2770 hermes:hermes). finn is
+    # this machine's one human user and already knows hermes-env's contents
+    # (typed them into sops directly), so this is not new exposure.
+    users.users.finn.extraGroups = [ "hermes" ];
+  };
+}
+```
+
+Add `./environments/hermes-agent` to `modules/environments/default.nix`;
+enable `my.profiles.hermes-agent.enable = true` in
+`machines/mibook/environments.nix`. `machines/configuration.nix` is **not**
+touched by this design.
+
+**Provided for free by the upstream module:** `hermes` system user/group
+(`createUser` default true), hardened systemd unit (`NoNewPrivileges`,
+`ProtectSystem=strict`, `PrivateTmp` — not independently user-configurable
+per the docs), `hermes` CLI on `$PATH` via `addToSystemPackages` (usable by
+finn once group membership is granted, above).
+
+## Part 2 — Secret
+
+Add to `machines/mibook/secrets.nix` (existing file, per `docs/secrets.md`):
+
+```nix
+sops.secrets.hermes-env = {
+  owner = "hermes";
+  group = "hermes";
+  mode = "0400";
+  restartUnits = [ "hermes-agent.service" ]; # confirm exact unit name at implementation
+};
+```
+
+Populate via `nix develop -c sops secrets/mibook.yaml`, adding a
+multi-line `hermes-env` block:
+
+```
+ANTHROPIC_TOKEN=<output of `claude setup-token`>
+TELEGRAM_BOT_TOKEN=<from @BotFather>
+TELEGRAM_ALLOWED_USERS=<your numeric Telegram user id>
+EMAIL_ADDRESS=<mailbox address>
+EMAIL_PASSWORD=<password or app-password>
+EMAIL_IMAP_HOST=<imap host>
+EMAIL_SMTP_HOST=<smtp host>
+EMAIL_ALLOWED_USERS=<your own sending address>
+```
+(`EMAIL_IMAP_PORT`/`EMAIL_SMTP_PORT` default to 993/587 — only set if the
+provider differs. See `website/docs/reference/environment-variables.md` for
+the full key list.)
+
+Both `*_ALLOWED_USERS` keys are access control, not optional: Telegram
+defaults to open DM pairing (any stranger who messages the bot gets a
+pairing code and can request approval), and email with no
+`EMAIL_ALLOWED_USERS` set **silently ignores** messages from unrecognized
+senders — no log line, no error. For an agent with terminal access on the
+daily driver, treat both as required.
+
+**Resolved (confirmed against the locked `hermes-agent` revision's source —
+`agent/anthropic_credentials.py`, `hermes_cli/providers.py`):** the module
+reads `ANTHROPIC_TOKEN` for the setup-token path. No longer an open
+question; see Open risks below for what replaced it.
+
+**Where this actually lands at runtime:** the upstream module does not use
+systemd `EnvironmentFile=`. An activation script concatenates every
+`environmentFiles` entry into **`/var/lib/hermes/.hermes/.env`**, mode
+`0640`, owned `hermes:hermes` — plaintext on mibook's plain ext4 root (no
+LUKS, per `machines/mibook/disks.nix`), not sops-nix's `/run/secrets`
+tmpfs. This is upstream behavior, not something this design controls; see
+Rollback below for why it matters.
+
+**Must `git add secrets/mibook.yaml` before `nix build`** — untracked
+files are invisible to flake evaluation (existing repo rule, `docs/secrets.md`).
+
+## Part 3 — Rollout runbook (on mibook)
+
+1. Confirm Claude Max extra-usage-credits are actually purchased (Anthropic
+   console) — the whole auth design depends on this pool being funded.
+2. Run `claude setup-token` on mibook; capture the token.
+3. Create/gather Telegram bot token (`@BotFather`) and email credentials.
+4. Add the `hermes-agent` flake input; add the module wrapper file; wire it
+   into `modules/environments/default.nix` and `machines/mibook/environments.nix`.
+5. Add `sops.secrets.hermes-env` to `machines/mibook/secrets.nix`.
+6. `nix develop -c sops secrets/mibook.yaml`, populate `hermes-env`, `git add`.
+7. `nix build '.#nixosConfigurations.mibook.config.system.build.toplevel'` — CI-style check before touching the running system.
+8. `sudo nixos-rebuild test --flake '.#mibook'` — verify before persisting across reboot.
+9. `journalctl -u hermes-agent.service -f` — confirm it starts, decrypts the secret, connects to Telegram (and doesn't loop-crash on the `ANTHROPIC_TOKEN` question from Part 2).
+10. Send a test Telegram message; send a test email; confirm both round-trip.
+11. `sudo nixos-rebuild switch --flake '.#mibook'` once verified.
+
+### Rollback
+`my.profiles.hermes-agent.enable = false`, `nixos-rebuild switch` stops the
+service, but does **not** clean up `/var/lib/hermes` — the plaintext
+`.env` (Anthropic token, Telegram token, email password) stays on disk
+indefinitely, per the persistence note in Part 2. A real rollback is:
+`sudo rm -rf /var/lib/hermes`, plus revoking the Telegram bot token
+(`@BotFather` → `/revoke`) since it can't be un-leaked once exposed. No
+data migration is involved, so this is still cheap — just not one command.
+
+## Open risks (carried forward, not resolved by design)
+
+1. ~~`ANTHROPIC_TOKEN` vs `ANTHROPIC_API_KEY`~~ — **Resolved**: confirmed supported by reading the locked `hermes-agent` revision's source (Part 2).
+2. **Extra-credits billing pool funding** — not independently verified, user-asserted intent (Part 3, step 1).
+3. **Tier 2 Nix support** — expect some manual troubleshooting; upstream doesn't guarantee the flake stays working across their commits.
+4. **Availability gap** — accepted by design, not a bug to fix later unless priorities change.
+5. **`ANTHROPIC_TOKEN` cannot refresh unattended.** The setup-token is a terminal value to the module's credential resolver; the refresh path needs a `~/.claude/.credentials.json` with a refresh token that the `hermes` service user won't have. When the token expires, the gateway silently stops authenticating and the operator has to re-run `claude setup-token` and re-populate the secret by hand — watch for this during the confidence window, not something this design solves.
