MiniMax moved their Anthropic-compatible API from api.minimax.io to api.minimaxi.chat. Update ANTHROPIC_BASE_URL in the minimax/v1 context harness and corresponding comments in init.sh and the TODO note. Model routing is unaffected: the API defaults unrecognised model names (e.g. "minimax" from the registry slug) to MiniMax-M3 already.

# minimax init — stage the api_key for the agent user and wire apiKeyHelper.
|
|
#
|
|
# Threat model: keep the ESO mount root-only (mode 0400) so the agent user
|
|
# cannot directly `cat` /run/agent/secrets/minimax/api_key. init.sh runs as
|
|
# root (in uid-wrapper.sh, before the gosu drop) and stages a per-secret
|
|
# copy into the agent's home with mode 0600 owned by agent. apiKeyHelper
|
|
# points at the COPY. This is the gitea-ssh pattern — only the file the
|
|
# harness explicitly grants is reachable by the runtime.
|
|
#
|
|
# Rotation handling: this is a one-shot copy at container start. For
|
|
# ephemeral container agents (one task = one container) every task starts
|
|
# with the latest secret. Long-running sessions don't refresh the copy
|
|
# until a future scripts.control_loop hook lands (planning E1-M3).
|
|
#
|
|
# Auth wire-up: apiKeyHelper output is sent as `Authorization: Bearer
|
|
# <value>` when ANTHROPIC_BASE_URL is non-anthropic.com — exactly what
|
|
# api.minimaxi.chat/anthropic requires. The secret value never enters this
|
|
# process' env, the claude subprocess' env, or /proc/<pid>/environ.
