loopsmith-provider 0.1.4

Part of loopsmith — self-evolving agent loops behind a deterministic verification gate.

You probably do not need to depend on this directly. It is a component of the loopsmith binary and compiles automatically as one of its dependencies:
cargo install loopsmith
Depend on it directly only if you are building something else on loopsmith's internals. The API is not yet stable across minor versions.

What this crate is

Every provider is a command template. That single decision is what makes bring-your-own-key free: Claude Code, Ollama, a Grok CLI, an OpenAI-compatible endpoint driven by curl, an MCP server over stdio — all of them are "a program you run with a prompt". Adding one is a config edit, never a rebuild.

Nodes ask for a tier (cheap, standard, strong) and a cascade decides which provider actually serves the call, falling through on failure or timeout. Judge independence can be enforced, so a judge never runs on the same provider as the builder whose work it is checking.

Secrets never enter the process. requires_env names variables that must exist; their values are never read, substituted into arguments, or written to the ledger. The command expands them itself, as curl does.

Crate	Purpose
`loopsmith`	the CLI binary
`loopsmith-util`	PATH lookup, wall clock, runtime platform detection
`loopsmith-core`	the A–J config model and its validation
`loopsmith-memory`	`sled`-backed episodes, goal state, ledger, checkpoints
`loopsmith-graph`	DAG scheduling, critical path, Amdahl-driven concurrency
`loopsmith-gate`	the deterministic verification gate
`loopsmith-provider`	provider routing and the tier cascade
`loopsmith-skills`	sub-agent acquisition, quarantine, outcome ranking
`loopsmith-mcp`	local stdio MCP server over memory, gate, and graph

The one rule the whole design rests on

A model must not be the thing that certifies its own completion.

goal_satisfied is written by loopsmith-gate and by nothing else, and the gate can revoke: delete a required artifact and a satisfied goal flips back.
