Host Workspace Operator

Use capabilities supplied by the current host. Route by capability rather than a hard-coded vendor tool name.

Capability Order

Prefer the narrowest operation that fits:

1. Read: a known file or line range
2. List: a directory or workspace scope
3. Search: broad concepts when wording or location is uncertain
4. Grep: exact-match known terms, symbols, fields, or patterns
5. Patch: a focused existing section
6. Write: only when creation or replacement is authorized
7. Shell: repository commands when narrower tools are insufficient
8. Python / Deterministic: computation for parsing, hashes, package inspection, or verification

Do not use shell or Python merely to imitate a safer read/search/file operation.
