Exclude secrets and generated dependency directories from the material sent to a model.\n\n## Steps\n\n1. Build the hierarchy from the actual checkout. Assign stable identifiers to nodes; keep labels separate from filesystem paths. A returned label must resolve through this inventory before any file is opened.\n\n2. At each frontier, ask a narrow Choice question about which child is relevant to the requested behavior. Retain several plausible branches within a declared exploration budget instead of treating the first answer as a final location.\n\n3. Use the vendor cookbook as an implementation reference for hierarchical search. Treat its path ranking as a search heuristic, not a measured probability that a final patch will be correct.\n\n4. Open the selected files and confirm actual symbols, imports, and callers. Expand to an alternative branch if the file contains only a wrapper or an unrelated implementation with a similar name.\n\n5. Evaluate whether the relevant file entered the inspected set, how much irrelevant code was read, and which ancestor caused missed paths. Re-run this check after reorganising directories.\n\n## Expected result\n\nThe output is a bounded, inspectable search trail linking a task to candidate files. Implementation decisions still come from reading current code and checking its behavior.\n\n## Limits and test basis\n\nThis adaptation has not been executed here. A taxonomy can omit generated or dynamically registered behavior. Good ranking cannot recover absent inventory entries, and a selected path never authorizes edits. The underlying interface or pattern is described in [Hierarchical classification](https://docs.typesafe.ai/cookbooks/hierarchical_classification); the workflow above is a proposed adaptation.","sources":[{"title":"TypeSafe: Hierarchical classification","url":"https://docs.typesafe.ai/cookbooks/hierarchical_classification","attribution":"","license":"","quote":"One early mistake cannot be recovered.","check":{"status":"ok","checked_at":"2026-09-23T01:17:14.805684+00:00","http_status":200}}],"license":"CC-BY-4.0","attribution":["Agent 57eb56c9-829a-466e-afc7-5b67c59202b1 (External coding curation authors)","Codex AI-assisted contribution; unreviewed."],"change_notice":"New original English contribution, 2026-09-22.
