## Embedded agent
Two entry points, one adapter (internal/agent):
- `ihme new <label> --agent [--grant ask|auto]` — scoped: runs the
SKILL.md procedure; pre-grants ONE reservation for that label and
touching only addresses created this run; everything else prompts.
- `ihme agent [task]` (alias `ihme --agent`) — general: interactive
TUI without args, one-shot with a task; nothing is pre-granted.
Code is the source of truth for the behavior; the load-bearing
comments live where the behavior lives:
- internal/agent/tui.go — interactive session: input authority,
consent card, typed-reply redirect, reasoning status line
- internal/agent/gate.go — the scoped-consent policy
- internal/agent/interact.go — consent protocol (y/N/a/reply)
- internal/agent/config.go, auto.go — BYOK config keys and
wire-protocol auto-detection
- internal/agent/run.go — system prompt, renderer, one-shot runs
- internal/agent/memtool.go — memory glue: the recall_memory /
remember tools, the <memory> continuity block injected at session
start, and the journal+page write made at reserve time
- internal/memory/memory.go — the graph store itself (journals,
pages, flashcards, derived link graph); package doc has the design
- skill/SKILL.md — the operational procedure. RUNTIME PROMPT
CONTENT (go:embed, invoked as a task turn): whenever tool schemas
in tools.go change, its embedded-agent section must change with
them, or the model reads two contracts.
- pkg/agentkit/README.md — kernel contract and invariants
Design rejections and their reasons: TASTE.md. When something needs
explaining, prefer (in order) a code comment at the behavior, a scar
in TASTE.md, or a where-to-look line here. Do not re-grow prose that
restates tui.go — it drifted within hours the last time; this
section has been composted once already.
## Auth flow
Apple SRP via idmsa.apple.com (web auth, not GSA):
1. GET /authorize/signin — init session
2. POST /federate — submit email
3. POST /signin/init — SRP key exchange
4. POST /signin/complete — SRP proof (M1/M2)
5. 2FA: SMS (PUT /verify/phone) or device push (PUT /verify/trusteddevice/securitycode)
6. GET /2sv/trust — trust token
7. POST setup.icloud.com/accountLogin — get webservices map + cookies
Cookie handling: manual Cookie header from session cookie list (rclone pattern).
No Go cookie jar domain matching — cookies go to all service requests.
CN accounts: auto-fallback to setup.icloud.com.cn on 421.
## Session resume
1. Load session + cookies from disk
2. If validatedAt is fresh (< 15 min), skip validation entirely —
commands start straight on saved cookies
3. Otherwise validate (uses persisted cookies, no sign-in email).
Failures are CLASSIFIED: only a definitive rejection (401/403/450
or success=false) falls back to accountLogin; transport trouble
(timeouts, 5xx, proxy flaps, 421 routing hiccups) gets one quiet
retry, then surfaces as "iCloud temporarily unreachable — your
session is probably still valid" WITHOUT touching accountLogin.
421 is NOT expiry: Apple returns it for routing/rate pressure on
valid sessions (the CN-region case is auto-retried separately).
4. accountLogin (triggers sign-in email) only on real rejection; its
own transient failures also report as unreachable, not expired
5. Save updated session (cookies + validatedAt) after resume
## Design rules
- Every command supports --json and --jq
- --json output includes hints with follow-up commands
- --help documents JSON response shapes
- <ref> resolves by anonymousId, email, or label (fuzzy)
- Errors include usage example and fix command
- Errors to stderr, data to stdout
- Exit codes: 0 success, 1 error, 2 auth required
- Session at ~/.config/ihme/session.json (respects $XDG_CONFIG_HOME), 0600
- --verbose/-v is global, logs all HTTP requests
