Module client_args 

Client-side resolution of path-like SessionConfig arguments (T4, F26).

When a thin client ships --system ./prompt.md to the daemon, the string ./prompt.md must be resolved against the client’s cwd, not the daemon’s. This module provides resolve_client_session_args which rewrites SessionConfig in place before Hello is sent.

Path-like heuristic for --system

A value is treated as a file path when it:

• starts with /, ./, ../, or ~, or
• ends with .md or .txt (case-insensitive)

and contains no embedded newlines or runs of whitespace longer than a single space (prose rarely looks like a path).

When path-like AND the file is readable, the value is replaced with the file’s contents. When path-like but missing/unreadable, an error is returned so the client can exit non-zero with a helpful message.

Non-path-like values pass through untouched (they are literal prompt text).

--prompt-manifest

Canonicalized against client_cwd. Missing → error with the resolved path.

Functions

looks_path_like

Returns true when the value looks like a file path rather than prose.

resolve_client_session_args

Resolve path-like arguments in cfg against client_cwd.
