* feat(gptel-tools): harden path validation with file-truename realpathCraig Jennings2026-05-161-13/+17
| | | | | | | | | | | | | | | | | | | | | | | | Resolves PATH through file-truename before applying home-directory and read/write checks across the path-handling tools (git_status, git_log, git_diff, move_to_trash, read_text_file, update_text_file, write_text_file, list_directory_files, read_buffer, web_fetch). Without the resolve step, a symlink under HOME pointing outside HOME would pass the prefix check but the tool would act on the real target -- a symlink-escape. move_to_trash also tightens the trash-bin construction (treats empty file extensions correctly) and switches the "critical directories" list to truename-resolved canonical forms so a symlinked ~/.config can't be trashed via an aliased path. update_text_file fixes an off-by-one in the line-count derivation when the source content is empty. Each source change pairs with tests in tests/test-gptel-tools-*.el and tests/test-update-text-file.el covering the realpath escape paths, the empty-extension trash case, and the empty-content line- count edge. Combined coverage is now 100% across all ten gptel-tools source files: 516 / 516 executable lines, 217 tests.
* feat(gptel-tools): wire update_text_file as a local tool with testsCraig Jennings2026-05-161-124/+206
| | | | | | | | | | | | | | | | | | | | | I rewrote `update_text_file.el` in pure Elisp. The previous version shelled out to sed for everything, had a stray quote terminator at EOF (line 149) that broke loading, produced literal backslash-n where actual newlines were expected, and prompted via `y-or-n-p` redundantly with gptel's own `:confirm t` flag. The five operations -- replace, append, prepend, insert-at-line, delete-lines -- split into pure string transforms that test without touching the disk. The file-level wrapper validates the path, enforces a 10MB size limit, takes a timestamped backup, and writes atomically. No backup is created when the operation is a no-op. Patterns are literal substrings (not regex) so the model can't trip over metacharacter quoting. `tests/test-update-text-file.el` covers Normal / Boundary / Error per operation plus the file-level wrapper. 48 tests green. Added `update_text_file` to `cj/gptel-local-tool-features` so gptel exposes the tool after restart.
