+# Agent-readable `account list` 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:** Let an agent holding only `EMCLI_KEY` run `emcli account list` and get a reduced JSON view (name, from, can_send), while admin keeps the full text table and `account add/edit/remove` stay admin-only.
+
+**Architecture:** Make `commandRole` subcommand-aware so `account list` routes to the agent role; branch the `list` renderer on whether the admin key is present (admin → existing text table; agent → standard `Success` JSON envelope). No schema change; `ListAccounts` already avoids decrypting secrets.
+
+**Tech Stack:** Go, standard library (`flag`, `encoding/json`), existing `internal/cli` envelope helpers and `internal/crypto` key loaders.
+
+## Global Constraints
+
+- Agent output is the existing JSON envelope shape: `{"error":bool,"error_detail":{...},"data":{...}}` via `Success(...)` / `Failure(...)` in `internal/cli/envelope.go`.
+- Admin `account list` output stays byte-for-byte the current human-readable table (`NAME MODE IMAP USER`).
+- The agent (reduced) view exposes only `name`, `from`, `can_send` — never the IMAP host/port or login username.
+- `from = Account.SendFrom()` (explicit `FromAddress`, else `Username`). `can_send = (Mode == "RW")`.
+- `account add/edit/remove` remain admin-only (hard-require `EMCLI_ADMIN_KEY`, no fallback).
+- Privilege detection: a caller is "admin" iff `crypto.AdminKeyFromEnv()` returns no error.
+- Spec: `docs/superpowers/specs/2026-06-23-agent-account-list-design.md`.
+
+---
+
+### Task 1: Route `account list` to the agent role and render by privilege
+
+**Files:**
+- Modify: `internal/cli/run.go` (`commandRole`, its call site in `Run`)
+- Modify: `internal/cli/admin.go` (the `list` branch of `runAccount`; add `crypto` import)
+- Modify: `internal/cli/role_test.go` (`TestCommandRole`)
+- Modify: `internal/cli/security_invariant_test.go` (refused-commands set)
+- Create/Test: `internal/cli/account_list_test.go`
+
+**Interfaces:**
+- Consumes: `store.Account.SendFrom() string`, `store.Account.Mode string`, `store.Store.ListAccounts() ([]store.Account, error)`, `crypto.AdminKeyFromEnv() ([]byte, error)`, `Success(map[string]any) Envelope`, `Failure(code, msg string) Envelope`, `Envelope.Write(io.Writer) error`, test helpers `adminEnv(t)`, `run(t, args...)`.
+- Produces: `commandRole(args []string) store.Role` (signature changes from `commandRole(cmd string)`). Agent `account list` emits `{"data":{"accounts":[{"name":string,"from":string,"can_send":bool}]}}`.
+
+- [ ] **Step 1: Rewrite `TestCommandRole` for the new signature and subcommand routing**
+
+Replace the body of `TestCommandRole` in `internal/cli/role_test.go` with:
+
+```go
+func TestCommandRole(t *testing.T) {
+	adminCmds := [][]string{
+		{"whitelist"}, {"config"}, {"audit"},
+		{"account"}, {"account", "add"}, {"account", "edit"}, {"account", "remove"},
+	}
+	agentCmds := [][]string{
+		{"list"}, {"get"}, {"search"}, {"ack"}, {"send"}, {"doctor"},
+		{"account", "list"},
+	}
+	for _, c := range adminCmds {
+		if commandRole(c) != store.RoleAdmin {
+			t.Errorf("%v should be admin", c)
+		}
+	}
+	for _, c := range agentCmds {
+		if commandRole(c) != store.RoleAgent {
+			t.Errorf("%v should be agent", c)
+		}
+	}
+}
+```
+
+Note: `init` is intentionally absent from this table. `commandRole({"init"})` falls through to the agent arm, but `Run` dispatches `init` via its own bootstrap path (which requires both keys), so its `commandRole` result is never used — asserting a role for it here would be both wrong and meaningless.
+
+- [ ] **Step 2: Run the routing test to verify it fails to compile**
+
+Run: `go test ./internal/cli/ -run TestCommandRole`
+Expected: FAIL — compile error, `commandRole` takes `string`, called with `[]string`.
+
+- [ ] **Step 3: Make `commandRole` subcommand-aware, update its call site, and fix the security invariant**
+
+In `internal/cli/run.go`, replace:
+
+```go
+func commandRole(cmd string) store.Role {
+	switch cmd {
+	case "account", "whitelist", "config", "audit":
+		return store.RoleAdmin
+	default: // list, get, search, ack, send, doctor
+		return store.RoleAgent
+	}
+}
+```
+
+with:
+
+```go
+func commandRole(args []string) store.Role {
+	switch args[0] {
+	case "account":
+		// account list is a read-only discovery view available to agents;
+		// add/edit/remove mutate config and require admin.
+		if len(args) >= 2 && args[1] == "list" {
+			return store.RoleAgent
+		}
+		return store.RoleAdmin
+	case "whitelist", "config", "audit":
+		return store.RoleAdmin
+	default: // list, get, search, ack, send, doctor
+		return store.RoleAgent
+	}
+}
+```
+
+In `Run`, change the call site from `role := commandRole(cmd)` to `role := commandRole(args)`.
+
+In `internal/cli/security_invariant_test.go`, in `TestAgentKeyCannotRunAdminCommands`, replace the `adminAttempts` entry `{"account", "list"}` so the set covers a *mutating* account command instead (account list is now allowed for agents):
+
+```go
+	adminAttempts := [][]string{
+		{"account", "add", "--name", "x", "--imap-host", "h", "--username", "u@x.com"},
+		{"config", "set", "audit_retention_days", "30"},
+		{"audit"},
+	}
+```
+
+- [ ] **Step 4: Run the cli package tests to verify routing + invariant pass**
+
+Run: `go test ./internal/cli/ -run 'TestCommandRole|TestAgentKeyCannotRunAdminCommands'`
+Expected: PASS (both). The agent can no longer be proven to refuse `account list` — that is intended; the invariant now proves `account add` is refused and the DB is unchanged.
+
+- [ ] **Step 5: Add the rendering tests (agent JSON view + admin text view)**
+
+Create `internal/cli/account_list_test.go`:
+
+```go
+package cli

+		t.Errorf("alerts: want from=alerts@example.com can_send=false, got %+v", g)
+	}
+}
+
+// With the admin key present, `account list` stays the full human-readable table.
+func TestAccountListAdminTextView(t *testing.T) {

+	run(t, "account", "add", "--name", "work", "--mode", "RW",

+		}
+	}
+	if strings.Contains(out, `"accounts"`) {
+		t.Fatalf("admin view should be text, not JSON:\n%s", out)
+	}
+}
+```
+
+- [ ] **Step 6: Run the rendering tests to verify the agent view fails**
+
+Run: `go test ./internal/cli/ -run 'TestAccountListAgentJSONView|TestAccountListAdminTextView'`
+Expected: `TestAccountListAdminTextView` PASS (already text); `TestAccountListAgentJSONView` FAIL — output is still the text table, so `json.Unmarshal` errors.
+
+- [ ] **Step 7: Split the `list` branch by privilege in `runAccount`**
+
+In `internal/cli/admin.go`, add the crypto import. Change the import block:
+
+```go

+- Modify: `skills/emcli/SKILL.md` (allowed-commands note, command table, do/don't)
+- Modify: `skills/emcli/AGENTIC-MANUAL.md` (§4 account discovery)
+
+**Interfaces:**
+- Consumes: behavior shipped in Task 1 (agent `account list` → `{"data":{"accounts":[{name,from,can_send}]}}`).
+- Produces: docs only; no code interface.
+
+- [ ] **Step 1: USER-MANUAL — note that `account list` is the one agent-readable admin view**
+
+In `USER-MANUAL.md`, in the "Two kinds of commands" block, change the Admin bullet (line ~36) from:
+
+```
+- **Admin commands** (`init`, `account`, `whitelist`, `config`, `audit`) require `EMCLI_ADMIN_KEY`
+  and are for *you*, the human. They print human-readable text or open an interactive form.
+```
+
+to:

+  `EMCLI_ADMIN_KEY` and are for *you*, the human. They print human-readable text or open an
+  interactive form. (`account list` is the one exception — it is also an agent command; see below.)
+```
+
+- [ ] **Step 2: USER-MANUAL — update the role table**
+
+Replace the role table rows (lines ~127-128):
+
+```
+| `list`, `get`, `search`, `ack`, `send`, `doctor` | Agent (`EMCLI_KEY` or `EMCLI_ADMIN_KEY`) |
+| `account`, `whitelist`, `config`, `audit` | Admin (`EMCLI_ADMIN_KEY` required) |
+```
+
+with:
+
+```
+| `list`, `get`, `search`, `ack`, `send`, `doctor`, `account list` | Agent (`EMCLI_KEY` or `EMCLI_ADMIN_KEY`) |
+| `account add/edit/remove`, `whitelist`, `config`, `audit` | Admin (`EMCLI_ADMIN_KEY` required) |
+
+`account list` is dual-role: with the admin key it prints the full `NAME MODE IMAP USER` table;
+with only `EMCLI_KEY` (an agent) it prints a JSON envelope exposing just `name`, `from`, and
+`can_send` — no host or login username.
+```
+
+- [ ] **Step 3: USER-MANUAL — annotate the cheatsheet**
+
+In the cheatsheet (line ~597), change:
+
+```
+emcli account list                                    # list accounts (no secrets)
+```
+

+emcli account list                                    # full table (admin) / name+from+can_send JSON (agent)
+```
+
+- [ ] **Step 4: SKILL.md — carve `account list` out of the forbidden-commands rule**
+
+In `skills/emcli/SKILL.md`, change the first bullet (lines ~20-24):
+
+```
+- **You only run agent commands:** `list`, `get`, `search`, `ack`, `send`, `doctor`. You are
+  provided only `EMCLI_KEY` (the agent key), which authorises these commands and nothing else.
+  Account setup, passwords, whitelists, and config are the **user's** job (admin commands that
+  require `EMCLI_ADMIN_KEY`) — do not run or suggest running `account`, `whitelist`, `config`,
+  `audit`, or `init`. You have only `EMCLI_KEY` (agent key); `emcli` will refuse admin commands
+  with a privilege error.
+```
+
+to:
+
+```
+- **You only run agent commands:** `list`, `get`, `search`, `ack`, `send`, `doctor`, and

+  do not run or suggest running `account add/edit/remove`, `whitelist`, `config`, `audit`, or
+  `init`. `emcli` will refuse those with a privilege error.
+```
+
+- [ ] **Step 5: SKILL.md — add `account list` to the command table**
+
+In the command table (after the `send` row, line ~122), add:
+
+```
+| `emcli account list` | Discover accounts: JSON `name` / `from` / `can_send` per account |
+```
+
+- [ ] **Step 6: SKILL.md — fix the "don't" bullet**
+
+Change (lines ~147-148):
+
+```
+- ❌ Don't run admin commands (`account`/`whitelist`/`config`/`audit`/`init`) — you have only
+  `EMCLI_KEY` (agent key); `emcli` will refuse admin commands with a privilege error.
+```
+
+to:
+
+```
+- ❌ Don't run admin commands (`account add/edit/remove`, `whitelist`, `config`, `audit`, `init`) —
+  you have only `EMCLI_KEY` (agent key); `emcli` will refuse them with a privilege error.
+  (`account list` is allowed — use it to discover accounts.)
+```
+
+Also change the ✅ bullet (line ~145) from `Ask the user for the account name; keep bodies plain text.` to:
+
+```
+- ✅ Discover accounts with `emcli account list`, or ask the user; keep bodies plain text.
+```
+
+- [ ] **Step 7: AGENTIC-MANUAL — document discovery via `account list`**
+
+In `skills/emcli/AGENTIC-MANUAL.md`, replace the body of `## 4. Find the account(s)` (lines ~88-97):
+
+```
+You refer to an account by name (e.g. `gmail`, `work`). Ask the user which account to use.
+`emcli doctor` is an agent command (authorised by `EMCLI_KEY`), so you can run it to check that
+configured accounts connect and authenticate:
+
+```bash
+emcli doctor              # all accounts
+emcli doctor --account gmail
+```
+
+Just take the account name from the user and start with the workflow in `SKILL.md`.
+```
+
+with:

+```
+You refer to an account by name (e.g. `gmail`, `work`). Discover the configured accounts yourself

+## Notes for the implementer
+
+- Run all Go commands from the repo root (`/home/steve/src/emcli`).
+- The two intentional red states are Step 2 (compile error) and Step 6 (agent JSON test) in Task 1. Every other test run must be green.
+- Do not change the admin text table or add columns to it — admin output must stay identical.
+- `adminEnv(t)` and `run(t, ...)` live in `internal/cli/admin_test.go`; `b64Key`/`b64AgentKey` in `internal/cli/run_test.go`. No new helpers are needed.

+# Agent-readable `account list` — design
+
+**Date:** 2026-06-23
+**Status:** Approved (brainstorm), ready for implementation plan
+**Author:** Steve + Claude
+
+## Problem
+
+An agent process is launched with only `EMCLI_KEY` (the two-key model — see
+`2026-06-22-two-key-privilege-design.md`). Every agent command takes
+`--account NAME`, but the agent has no way to *discover* which accounts exist:
+`account list` is classified admin-only and is refused under the agent key. So
+account names must be supplied to the agent out of band, which is brittle and
+defeats the point of a self-directed agent.
+
+The two-key spec deliberately gated the whole `account` command to admin because
+`account add/edit/remove` mutate configuration. But `account list` is read-only
+and exposes no secrets — `store.ListAccounts` never decrypts the password
+(`enc_password` is scanned and discarded). Gating *discovery* behind admin is
+stricter than the threat model requires.
+
+## Goal
+
+Let an agent holding only `EMCLI_KEY` run `account list` to discover the
+accounts it may operate on, while:
+
+- keeping `account add/edit/remove` admin-only (mutation stays gated);
+- exposing to the agent only what it needs — **account name, the send-as From
+  address, and whether the account can send** — and *not* the IMAP host/port or
+  login username;
+- preserving the admin's existing full-detail view unchanged.
+
+## Constraints / decisions
+
+Settled during brainstorming:
+
+1. **Scope is exactly `account list`.** `whitelist list`, `config get`, and
+   `audit list` stay admin-only. `audit` in particular is oversight data and
+   must remain invisible to the agent.
+2. **Privilege-dependent rendering.** The admin keeps the current full table
+   (`NAME  MODE  IMAP  USER`, human-readable). The agent gets a *reduced* view
+   containing only name, From, and send-capability.
+3. **Agent output is JSON.** The agent is a machine consumer, so its
+   `account list` emits the standard agent envelope (like `list`/`get`/`search`),
+   not a text table. The admin path stays human-readable text.
+4. **No secret exposure, no schema change.** `ListAccounts` already avoids
+   decrypting passwords; nothing about the data model changes.
+
+## Approach
+
+Reclassify `account list` to the agent role, and branch rendering on the
+caller's actual privilege (presence of the admin key).
+
+### Routing (`internal/cli/run.go`)
+
+`commandRole` becomes subcommand-aware for `account`:
+
+- `account list` → `RoleAgent`
+- `account add | edit | remove` (and bare `account`) → `RoleAdmin`
+- all other commands unchanged.
+
+`commandRole` currently takes `cmd string`; it changes to take the full
+`args []string` so it can peek at the `account` subcommand. `Run` passes
+`args` through. This keeps `commandRole` the single source of truth for the
+classification table.
+
+Authorization mechanics are unchanged: `openStore(RoleAgent)` requires
+`EMCLI_KEY` (falling back to the admin key for a human who holds only that and
+runs `account list`). `account add/edit/remove` still hard-require
+`EMCLI_ADMIN_KEY` with no fallback.
+
+### Rendering (`internal/cli/admin.go`, the `list` branch)
+
+Determine privilege from the environment: `_, err := crypto.AdminKeyFromEnv()`;
+`isAdmin := err == nil`. (Holding the admin key *is* being the admin in this
+trust model. A human with only the admin key still gets the admin view; an agent
+with only `EMCLI_KEY` gets the reduced view.)
+
+- **Admin** → existing full table, unchanged:
+  ```
+  NAME             MODE IMAP                         USER
+  work             RW   imap.example.com:993         me@example.com
+  ```
+- **Agent** → JSON envelope to stdout:
+  ```json
+  {"error":false,"error_detail":{},"data":{"accounts":[
+    {"name":"work","from":"me@example.com","can_send":true},
+    {"name":"alerts","from":"alerts@example.com","can_send":false}
+  ]}}
+  ```
+  where `from = Account.SendFrom()` (the configured From address, falling back
+  to the username) and `can_send = (Mode == "RW")` (RW accounts have SMTP
+  configured; RO cannot send). The IMAP host/port and the raw login username are
+  **not** emitted (when From falls back to the username it may coincide with it,
+  which is acceptable — the user asked for From specifically).
+
+The reduced view reuses the existing `Success(...)` envelope and `Envelope.Write`
+helper; no new output machinery.
+
+## Error handling
+
+- Agent key on `account add/edit/remove` → unchanged:
+  `emcli: this command requires EMCLI_ADMIN_KEY (admin privilege)`, non-zero.
+- Agent `account list` with neither key set → the agent-command config error
+  (`EMCLI_KEY is not set`), surfaced the same way other agent commands surface a
+  missing key. Because the agent path now emits JSON, a missing-key failure on
+  `account list` is a JSON `Failure(CodeConfig, …)` envelope, consistent with the
+  other agent commands.
+- DB/list errors on the agent path → `Failure(CodeDB, …)` envelope; on the admin
+  path → existing `list: <err>` text to stderr.
+
+## Testing
+
+- **Routing:** extend the `commandRole` table test — `account list` → agent;
+  `account add` / `account edit` / `account remove` → admin.
+- **Agent view:** with only `EMCLI_KEY`, `account list` exits 0, emits a valid
+  envelope, and the `data.accounts` entries carry `name`/`from`/`can_send` — and
+  the output does **not** contain the IMAP host or the login username.
+- **Admin view:** with `EMCLI_ADMIN_KEY`, `account list` still prints the full
+  `NAME MODE IMAP USER` table (regression guard).
+- **`can_send`:** an RW account yields `can_send:true`, an RO account
+  `can_send:false`; `from` reflects `SendFrom()` (explicit From, else username).
+- **Security invariant (`security_invariant_test.go`):** remove
+  `{"account","list"}` from the refused-commands set (it is now allowed) and
+  replace it with a *mutating* `account add …` attempt, so the "forced agent
+  cannot run admin commands and the DB is byte-for-byte unchanged" invariant
+  still covers the `account` family.
+
+## Documentation updates
+
+- **USER-MANUAL:** role/command table — `account list` is agent-readable
+  (reduced JSON view); `account add/edit/remove` remain admin.
+- **`skills/emcli` (SKILL.md / AGENTIC-MANUAL.md):** document that the agent
+  discovers accounts via `account list`, including the JSON shape
+  (`name`, `from`, `can_send`).
+
+## Out of scope
+
+- Agent access to `whitelist list`, `config get`, or `audit list`.
+- Any change to the admin `account list` columns or to the data model.
+- JSON output for the admin `account list` path (stays human-readable text).
