Function canonical_tool_name

src/tool_command/args.rs:28–36

Normalize a user-supplied tool name to the canonical `tracedecay_ ` form used by the MCP registry. Accepts aliases (e.g. `query` → `search`), strips a leading `tracedecay_` if present, and converts dashes to underscores so `dead-code` and `dead_code` both work.

(raw: &str)

/// strips a leading `tracedecay_` if present, and converts dashes to
/// underscores so `dead-code` and `dead_code` both work.
pub(crate) fn canonical_tool_name(raw: &str) -> String {
    let trimmed = raw.strip_prefix("tracedecay_").unwrap_or(raw);
    let normalized = trimmed.replace('-', "_");
    let mapped = NAME_ALIASES
        .iter()
        .find(|(k, _)| *k == normalized)
        .map_or(normalized.as_str(), |(_, v)| *v);
    format!("tracedecay_{mapped}")
}

/// Parse CLI args against the tool's JSON Schema. Returns the JSON object to
/// hand to the handler, plus side-effects from reserved flags.
