Trait SkillWriter 

pub trait SkillWriter: Send + Sync {
    // Required method
    fn write_skill(
        &self,
        description: String,
        signature: String,
    ) -> Pin<Box<dyn Future<Output = Result<(), String>> + Send + '_>>;
}

Trait for writing a generated SKILL.md to disk.

Implemented in zeph-core using zeph_skills::generator::SkillGenerator. Defined here to avoid a circular crate dependency.

Contract

Implementors must:

• Generate a valid SKILL.md from description.
• Apply any configured evaluator gate before writing.
• Return Ok(()) on success or evaluator rejection (rejection is not an error).
• Return Err only on hard failures (LLM error, I/O error).

Required Methods

fn write_skill( &self, description: String, signature: String, ) -> Pin<Box<dyn Future<Output = Result<(), String>> + Send + '_>>

Generate and persist a SKILL.md from description.

signature is used as an idempotency key — callers should ensure the skill file does not already exist before calling this method.

Errors

Returns an error string on generation or I/O failure.
