mroberts b8bf9f9eff Pre-fill the alert permissions and test the plugin manifest parsing
Two of the three permissions treated as manual are in fact pre-fillable. The
earlier check scraped the rendered docs page, whose table splits those rows in
a way the parse missed; the docs source lists secret_scanning_alerts and
vulnerability_alerts as supported query parameters. Only checks is genuinely
absent, so the manual list shrinks to that one entry.

That entry now names what breaks without it. Checks: Read governs the status
rollup behind gh pr checks and the annotations behind gh run view, and both
degrade to empty results rather than permission errors, so an unticked box
reads as a broken CI integration rather than a missing scope.

The marketplace and enabled-plugin extraction move out of the install function
into host_marketplaces and host_enabled_plugins so they can be exercised
directly. The tests cover the pipe separator that keeps an absent repo from
shifting a url leftwards, rejection of marketplace sources that are neither
github nor git, disabled plugins being excluded, and the allowlist refusing to
carry credentials, transcripts or history.

Usage:
mise run ai:sbx -- setup [options]
mise run ai:sbx -- token
mise run ai:sbx -- refresh
mise run ai:sbx -- config
mise run ai:sbx -- run [-- agent arguments...]
mise run ai:sbx -- status
mise run ai:sbx -- remove
Setup opens a pre-filled GitHub token form in your browser. Use "token" on
its own to replace an expired or revoked token later.
Set AI_SBX_TEMPLATE in your mise config to reuse one custom image across
every repository without repeating --template.
For the claude agent, setup copies your user-level configuration (CLAUDE.md,
AGENTS.md, agents, commands, hooks, skills) into the sandbox and installs the
marketplaces and plugins your host has enabled. Credentials, transcripts and
history are never copied. Use "config" to re-apply after the host changes.
Setup and run install mise in the sandbox and resolve the repository's
pinned tools, so the agent runs the same versions you do. A personal
mise config that must stay out of the repository goes in the per-repository
config directory as mise.local.toml; it is copied to the workspace root on
every run. Repositories without any mise configuration are left alone.
Setup options:
--aws-profile NAME Host AWS profile to expose inside the sandbox.
May be supplied more than once. A trailing
-readonly is stripped from the profile name
written into the sandbox.
--agent NAME Sandbox agent. Default: claude
--direct Mount the host working tree read-write.
--clone Give the agent a private in-container clone
of the repository, mounted read-only.
Its commits reach the host through the
sandbox-<name> git remote. This is the default.
--template REF Custom sandbox image. Defaults to
AI_SBX_TEMPLATE when set.
--stock-template Ignore AI_SBX_TEMPLATE and use the agent's
stock image.
--kit PATH Mixin kit to apply. May be supplied more
than once.
--replace Replace the existing sandbox.
Examples:
mise run ai:sbx -- setup \
--aws-profile api-portal-readonly \
--aws-profile prod-readonly
mise run ai:sbx -- run
mise run ai:sbx -- run -- --dangerously-bypass-approvals-and-sandbox \
