Shared library

Load only the reference or script needed by the current skill. This marker keeps the library discoverable as one installation unit; it does not guarantee identical loading behavior across hosts.

Resolve shared resources

A path such as shared/references/model-roster.md is relative to the skill collection, not the user's project directory.

1. Use the loaded shared skill's directory when available.
2. For a source checkout, use skills/shared/ under this repository.
3. For a flat installation, find shared/ beside the installed skills. If it is missing, report the missing library dependency instead of guessing a path or silently skipping a contract.

Before a shell command, set SHARED_DIR to that resolved absolute directory in the same command. Other skills resolve their own scripts from their loaded skill directory. The scripts/skill_paths.py helper supports repository scripts that must find skills in both nested and flat layouts.

Contents

1. references/: workflow stages, model routing, runner behavior, evidence, handoffs, and run state.
2. scripts/: runner discovery, jobs, output handling, and validation.
3. tests/, schemas, and hooks: executable checks and shared formats.
