Read files or directories with a local model so you don't have to; get back a short answer. Use instead of Read/Grep when you need facts from large or many files but not the files themselves ("which routes lack auth", "where is X handled", "what does this module do"). Each fact comes with a quote verified verbatim in the source and its real path:line; facts the model could not quote are dropped. mode='summary' adds a short unverified summary. quality: leave unset (auto: the bigger model for negative questions or when the fast one finds nothing), True to force it. Do not use for decisions (security, correctness) without opening the cited lines.

Triage a long log or command output file (CI log, test output, server log) locally. Returns the root-cause error and distinct failures with verified path:line quotes, instead of loading the whole file into context. Tip: redirect a noisy command to a file, then digest it.

Apply a small, fully specified mechanical change with a local model (docstrings, comments, type hints, renames, boilerplate, test scaffolding, applying a decided pattern). Pass paths, not contents: do not Read the files first. gate = commands (argv lists, at most 5, no shell, run with the user's rights: only the project's own tests or linters) that must pass, e.g. [["python","-m","pytest","-q"]]; if they fail after one retry the files are restored and the result is ESCALATE. Returns APPLIED with the diff to review, or ESCALATE. Never for design, debugging or security-sensitive code.
