Crate chio_workflow 

Skill and Workflow Authority for Chio.

This crate extends the Chio capability model with multi-step skill composition. A skill is an ordered sequence of tool invocations with declared I/O contracts, dependency relationships, and budget envelopes.

Core concepts

• SkillGrant – extends capability model for ordered tool sequences
• SkillManifest – describes tool dependencies, I/O contracts, budget
• WorkflowReceipt – captures complete execution trace as single artifact
• WorkflowAuthority – validates each step against declared scope and budget

Example

let manifest = SkillManifest { ... };
let authority = WorkflowAuthority::new(signing_key);
let execution = authority.begin(&manifest, &capability)?;

for step in &manifest.steps {
    authority.validate_step(&execution, step, &arguments)?;
    // ... invoke tool ...
    authority.record_step_result(&mut execution, step, result)?;
}

let receipt = authority.finalize(execution)?;
