Crate systemprompt_loader 

File and module discovery infrastructure for systemprompt.io.

Reads the active services-config (with include resolution and deduplication), loads profile YAML, writes agent files, and discovers extension manifests under extensions/. Sits one level above systemprompt_config in the dependency graph so that domain crates never need to know how the on-disk layout is structured.

Modules

• config_loader — loads and merges services.yaml and its includes.
• config_writer — creates, edits, and deletes agent files.
• extension_loader / extension_binary_index — discover extension manifests and resolve binary paths.
• module_loader — inventory-driven extension discovery for the compiled-in extension trait registry.
• profile_loader — reads, validates, and writes profile YAML.
• bundle — signed services bundles: fetch, verify, compose, and the boot path that installs the active services root.
• vertex_discovery — boot-time catalog discovery: each provider’s credential decides which CatalogSource may list it, and every priced, serverless model it returns is folded into the provider registry.
• boot — BootContext, the owned profile, secrets, resolved config and services root the entry crates build once at startup.
• services_state — ServicesState, the owned services config, its resolved catalog and the discovery report, built once at boot and handed to every consumer.
• error — public error types (ConfigLoadError, ConfigWriteError, ExtensionLoadError).

Modules

boot

The owned boot sequence: profile, secrets, config, services root.

bundle

Signed services bundles: packing, fetching, verifying and composing.

config_loader

Reads, parses, and merges the active services configuration.

config_writer

Writes individual agent files and patches the top-level config to drop their includes: entries.

error

Error types raised by the loader infrastructure.

extension_binary_index

In-memory index of discovered extensions used to resolve binary paths at runtime, with a separate code path for cloud deployments where every binary lives in a single configured directory.

extension_loader

Discovers extensions/<name>/manifest.yaml files and resolves the binaries those manifests reference.

module_loader

Thin wrapper around the inventory-driven extension registry.

profile_loader

Reads, validates, writes and enumerates layered profiles.

services_state

The owned services-config state.

subprocess

Process supervision for the agent and MCP children this installation owns, and for its API server: the one place that spawns, identifies, probes and stops them.

vertex_discovery

Boot-time discovery of the models a deployment can actually serve.
