Check and upgrade BMC firmware and BIOS on ASUS ESC8000-E12P (and similar ASMB12/AST2600 AMI-BMC ASUS servers) via Redfish and the BMC's HPM wizard API. Use when asked to check firmware/BIOS versions, update BMC or BIOS on ASUS GPU servers, or recover a BMC stuck in firmware-update/flash mode (login blocked, Redfish 503).

description	Check and upgrade BMC firmware and BIOS on ASUS ESC8000-E12P (and similar ASMB12/AST2600 AMI-BMC ASUS servers) via Redfish and the BMC's HPM wizard API. Use when asked to check firmware/BIOS versions, update BMC or BIOS on ASUS GPU servers, or recover a BMC stuck in firmware-update/flash mode (login blocked, Redfish 503).

ASUS ESC8000 BMC/BIOS Upgrade

Validated end-to-end on ESC8000-E12P (ASMB12-iKVM, AMI SP-X gen13). BMC updates are host-safe; BIOS updates require the chassis powered OFF and a host reboot.

Quick start — check current + latest versions

export BMC_PASSWORD='...'
scripts/check_versions.sh <BMC_IP>                  # current BMC FW, BIOS, power state
scripts/check_versions.sh <BMC_IP> ESC8000-E12P     # + latest versions from ASUS API

Download zips from the URLs the ASUS API returns. BIOS zip → .HPM (BMC-flashable) + .CAP (EzFlash only — don't use here). BMC zip → .hpm.

Workflow A — BMC firmware (host keeps running)

scripts/bmc_update.sh <BMC_IP> <BMC_fw.hpm>

Does: preserve-config flags → Redfish multipart push → flash → BMC auto-reboot → version verify. ~10 min. Warning: after the BMC reboots, the host may power ON via power-restore policy — re-check chassis state before any subsequent BIOS work.

Workflow B — BIOS (chassis must be OFF)

Confirm with the operator that the host may go down; gracefully shut it down: POST /redfish/v1/Systems/<id>/Actions/ComputerSystem.Reset {"ResetType":"GracefulShutdown"} and wait for PowerState: Off.
Flash (script enforces a power-off gate and exits update mode on any failure):
```
python3 scripts/bios_update.py --ip <BMC_IP> --file <BIOS.HPM>
```
Power on: {"ResetType":"On"}. First POST takes 5–15 min (memory retraining). BiosVersion in Redfish flips mid-POST; then verify the OS comes back.

Update BMC first, then BIOS (paired releases). Do not run two flashes concurrently.

If the BMC is bricked in flash mode (the "3ed" state)

Symptoms: web UI loads but login returns {"error":"Could not login","code":1348} ("Firmware update in progress hence login has been blocked"), Redfish 503, SSH/IPMI/KVM ports closed. No remote fix exists once all sessions are gone — it never times out.

→ AC drain: unplug both PSU cords (or PDU outlets) 30 s, replug. BMC boots clean in ~3 min. Prevention: never abandon the firmware wizard mid-flow; the scripts here always exit update mode on failure, and hpm/exitupdatemode {"FWUPDATEID":N} works from ANY admin session.

Key gotchas (full details in REFERENCE.md)

Managers/Self & Systems/Self are invalid — discover members (Managers/BMC_0, Systems/System_0).
BMC reset type is ForceRestart; reset bounces the host ON via power-restore policy.
Redfish multipart needs THREE parts incl. OemParameters={"ImageType":"HPM"}.
The Redfish UpdateService/upload path CANNOT flash BIOS (demands an unsatisfiable BiosUpdateMethod) — use the HPM wizard API (Workflow B).
After the wizard upload you MUST call PUT hpm/flash — without it the flash never starts and upgradestatus returns 500 code 1442 "Error in HPM Finish Firmware Upload".
ipmitool hpm upgrade does not work: 0xD5 refusal, and ~3 KB/s if it runs at all.
PreserveConfiguration flags default to FALSE — set them before BMC flash or lose network/users.

See REFERENCE.md for the complete API map, payloads, and error-code table.

ssh-claude-auth

soulmachine/skills

Fix Claude Code appearing logged-out over SSH on a headless macOS machine — its credentials sit in the login keychain, which stays locked in SSH/headless sessions. Offers two fixes and asks the user to choose: a keychain-free long-lived OAuth token (recommended), or auto-unlocking the login keychain with a stored password. Use when Claude Code shows unauthenticated over SSH on a Mac, when setting up a Mac mini or headless Mac for remote/CI Claude Code use, or when `security show-keychain-info` reports the login keychain locked.

Set up Google Chrome on macOS to always launch with the Chrome DevTools Protocol enabled (127.0.0.1:9222) via a Dock launcher app, so local AI agents (Playwright, Puppeteer, browser-use, OpenClaw) can drive the real logged-in browser. Use when the user wants to enable a CDP/remote-debugging port for Chrome, connect an agent to Chrome, test a CDP connection, or troubleshoot/revert an existing Chrome-CDP Dock setup.

Use when setting up a Mac (especially Mac Mini or Apple Silicon Mac Studio) for unattended 24/7 server operation, headless use, or remote-only access. Covers sleep prevention, screen saver, Wake-on-LAN, auto-restart, App Nap, SSH enablement, and — on Apple Silicon — a caffeinate LaunchDaemon that stops the headless display from parking (physical panel and VNC/screen-share going black even with displaysleep=0). Targets macOS 15 (Sequoia) and later.
