-### Claude Code plugins
-
-The harness installs Claude Code plugins before the serve loop opens.
-Two per-agent `agent.nix` options control this:
-
-```nix
-hyperhive.claudeMarketplaces = [ "anthropics/claude-plugins-official" ];  # default
-hyperhive.claudePlugins = [ "formatter@my-marketplace" ];                  # default: []
-hyperhive.claudePluginsAutoUpdate = false;                                 # default
-```
-
-- **`claudeMarketplaces`** — list of marketplace sources passed to
-  `claude plugin marketplace add <source>`. The official Anthropic
-  marketplace is pre-configured by default; override or extend to add
-  custom marketplaces. Idempotent — re-adding an existing source is
-  a no-op.
-- **`claudePlugins`** — list of plugin specs passed to
-  `claude plugin install <spec>`. Empty by default. Each spec is
-  installed on every boot (`install` is expected to be idempotent);
-  failures log a warning but do not abort boot.
-- **`claudePluginsAutoUpdate`** — when `true`, runs
-  `claude plugin marketplace update` before installing plugins to pull
-  the latest index. Disabled by default to keep boot times short and
-  plugin versions pinned.

-### `cargo.shortMessages`

-```nix
-hyperhive.cargo.shortMessages = true;  # default
-```
-
-When enabled (the default), the harness injects a `cargo` shell
-function into `/etc/hyperhive/bash-env.sh` that transparently appends
-`--message-format short` to compile subcommands (`build`, `check`,
-`clippy`, `test`, `run`, `doc`, `bench`, `install`, `rustc`, `fix`).
-This suppresses the per-crate progress lines that flood the response
-window, leaving only warnings and errors.
-
-The function handles `+toolchain` selectors (`cargo +nightly build`)
-and passes through cleanly when `--message-format` is already present.
-Non-compile subcommands (`new`, `add`, third-party `cargo-*`) are
-left untouched.
-
-Set to `false` for agents that parse cargo's JSON output
-programmatically and do not pass `--message-format json` themselves.
