plugin_cli.rs

//! The `bamboo plugin install|list|remove|update` CLI — a thin HTTP client
//! over a running `bamboo serve` instance's `/api/v1/plugins` routes.
//!
//! Mirrors the `bamboo mcp ...` verb pattern in [`crate::admin_cli`]: this
//! module only builds request bodies, resolves the base URL (via the shared
//! [`ConnArgs`]) and pretty-prints responses. The server (built in parallel
//! against the same frozen contract) is the single source of truth for
//! whether an install/update/remove actually succeeds.
//!
//! Wire contract (frozen — see `PLUGIN_PLAN.md` §"2. CLI agent" / §"3. HTTP
//! agent"):
//! - `GET /api/v1/plugins` -> `{ "plugins": [ { id, name?, version, source,
//!   status, registered: { mcp_server_ids, preset_ids, skill_dirs,
//!   workflow_filenames } } ] }`
//! - `POST /api/v1/plugins/install` -> body `{ "source": <SourceSpec> }`
//!   (`InstallDisposition::FailIfInstalled`); `SourceSpec` is one of
//!   `{"type":"local_dir","path":"..."}` / `{"type":"local_archive","path":"..."}`
//!   / `{"type":"url","url":"...","sha256":"..."?,"allow_unverified":bool?,
//!   "allow_untrusted_host":bool?,"allow_unsigned":bool?,"insecure":bool?}` —
//!   the same tagged shape as `bamboo_plugin::registry::PluginSource`'s
//!   `#[serde(tag = "type")]` wire form, reproduced here by hand (this crate
//!   does not depend on `bamboo-plugin`, to stay decoupled from the parallel
//!   installer-core branch).
//! - `POST /api/v1/plugins/{id}/update` -> same body shape (`Upgrade`).
//! - `DELETE /api/v1/plugins/{id}` -> uninstall.
//! - Errors: 409 (Conflict / AlreadyInstalled), 422 (UnsupportedPlatform), 404
//!   (NotFound), 403 (`url` source: untrusted host / unsigned-or-untrusted
//!   signature), 400 (bad manifest/artifact/bundle checksum, or a `url`
//!   install missing both `sha256` and `allow_unverified`); body
//!   `{"error": "..."}`.
//!
//! # URL installs: three trust layers, secure by default
//!
//! A `url` source is checked against three independent, stacked layers (see
//! `bamboo-server`'s `plugin_source.rs` module docs for the full precedence):
//!
//! 1. **Host allowlist** — the URL's host+path must match an operator-trusted
//!    prefix (`plugin_trust.trusted_hosts` in `config.json`; the default
//!    trusts `github.com/bigduu/`) unless `--allow-untrusted-host` is passed.
//! 2. **Signature** — the bundle's `<url>.sig` must verify against an
//!    operator-trusted ed25519 key (`plugin_trust.trusted_keys`; the default
//!    trusts nova's official signing key) unless `--allow-unsigned` is
//!    passed.
//! 3. **Checksum** — `sha256` pins the downloaded BUNDLE (the `plugin.json`,
//!    or the archive containing it) — NOT merely the per-platform binary
//!    artifact declared inside the manifest (that is separately, and always,
//!    sha256-verified against the manifest's own declaration). A `url`
//!    install with neither `sha256` nor `allow_unverified: true` is refused
//!    UNLESS layer 2 already verified a signature (a verified signature is a
//!    stronger integrity+authenticity guarantee than a pasted checksum, so it
//!    satisfies this layer on its own).
//!
//! Net effect: installing the OFFICIAL nova plugin from its GitHub release
//! needs NO flags at all once nova's release CI signs the bundle (trusted
//! host + verified signature). An install from an untrusted host or an
//! unsigned/untrusted-signature bundle needs the matching explicit opt-out
//! flag(s) — `bamboo plugin install <url>` alone no longer just downloads
//! and trusts any tar.gz from any host.
//!
//! # `--insecure`: skip ALL three layers at once
//!
//! `--insecure` (`install`/`update`) is a convenience AGGREGATE over the
//! three flags above — equivalent to passing `--allow-untrusted-host
//! --allow-unsigned --allow-unverified` together, for the one install it's
//! given on. It only turns default-required checks OFF: a `--sha256` passed
//! alongside `--insecure` is still verified (a mismatch still refuses the
//! install) — the flag never downgrades a check the caller explicitly opted
//! into. There's also a persistent, config-level form for a private/dev
//! bamboo instance that never wants to pass flags at all:
//! `bamboo config set plugin_trust.enforcement off` makes EVERY `url`
//! install/update behave this way with no per-install flag needed
//! (`plugin_trust.enforcement` defaults to `"strict"`, so this is always an
//! explicit opt-in relaxation). Use either only for sources you fully trust
//! (dev/self-hosted/custom setups) — the server logs a prominent warning for
//! every insecure install (plus its own startup warning when
//! `plugin_trust.enforcement` is `off`) and records the aggregate in
//! provenance, visible via `bamboo plugin list --json`.
