  $ pathfinder --help
pathfinder — semantic path finder & MCP resolution server

USAGE
    pathfinder [OPTIONS]          Interactive semantic directory finder (default).
    pathfinder --mcp [OPTIONS]    Start as an MCP server.

FINDER OPTIONS
    --include-builds    Include build/artifact dirs (target, dist, …).

MCP OPTIONS
    --root <PATH>       Add a project root directory to watch and index.

GENERAL OPTIONS
    -h, --help          Print this help message and exit.
    -V, --version       Print version, model, and PCA config.

MCP TOOLS
  1. path_resolve        Resolve a failed file path to the best match.
  2. tool_retry_with_resolve  Resolve + retry the operation in one call.
  3. roots_list          Return configured root directories.
  4. reindex_paths       Force a full index rebuild.

ENVIRONMENT VARIABLES
    PF_MCP_INFERENCE    Inference mode: "general" (default) or "code".
    Models (both INT8 quantized):
      general → mxbai-edge-colbert (17M, 48-dim)
      code    → lateon-code-edge (17M, 48-dim)
  

  1. pathfinder  → LLM のパス typo を解決（ENOENT → tool_retry_with_resolve）
2. ctree check → スナップショット更新、変更されたシンボルのハッシュを取得
3. get_baseline → コードベースの浅い俯瞰を得る
4. 関心のあるシンボルを特定 → Serena の find_symbol で定義・参照を深掘り
5. get_revs + get_text → 変更されたシンボルの詳細を取得
