An agent harness is software that installs the skill and runs its documented commands for the user. It needs Python 3.10 or newer and Full Disk Access for the terminal or agent harness. It is free under the MIT license. This listing delivers the complete package, including the Python script, documentation, and tests.\r\n\r\nThe tool lists chats with handles, message counts, and last dates; searches message text; and exports one selected chat as JSON Lines and an escaped text transcript.\r\n\r\nApproval-gated means a live export requires the digest from a matching dry run through --approve. The digest binds the chosen chat, fully resolved destination, parent and existing output device/inode identities, directory creation action, and exact output, so changes require a fresh preview. Review the destination and personal content before approving.","intended_users":"macOS users who want to inspect their own local Messages conversations with an Agent Skills compatible harness or directly from a terminal.","example_tasks":"List the 20 most recent conversations and their handles.\r\nSearch for a phrase in chats containing a participant, or use --from to find only that participant's messages.\r\nFind messages within a date range and request JSON output.\r\nPreview an export of one chat to a new local directory, then approve the matching digest.\r\nSummarize a bounded set of messages without sending anything.","setup_instructions":"Download the complete package into the skills directory used by your agent harness; keep SKILL.md, scripts/, references/, and agents/ together. Consult the harness documentation for its installation instructions. In macOS System Settings > Privacy & Security > Full Disk Access, enable the terminal or agent harness, then restart that application.\r\n\r\nRun from the package directory:\r\npython3 scripts/message_history_reader.py chats --limit 20\r\npython3 scripts/message_history_reader.py search --text 'meeting' --handle HANDLE --limit 20\r\npython3 scripts/message_history_reader.py search --text 'meeting' --from HANDLE --limit 20\r\npython3 scripts/message_history_reader.py export --chat CHAT_ID --out ./my-export --dry-run\r\npython3 scripts/message_history_reader.py export --chat CHAT_ID --out ./my-export --approve DIGEST\r\n\r\nRead SETUP.md for permission details and examples.","limitations":"Local database schemas may change across macOS versions. The tool does not send, edit, or delete messages. It does not extract attachments or all rich-text structures. An attributedBody it cannot decode or a refused symlink or irregular SQLite sidecar is listed as skipped, reported as incomplete, and exits 2 unless --allow-partial is selected. Existing output files and symlinks are refused.\r\n\r\nVersion 0.1.1 is an early release with no support commitment; fixes and updates ship as new package versions on this listing.\r\n\r\nEach database or sidecar is limited to 128 MiB. Sequential copies are not an atomic snapshot of a changing database. Export parents must already exist; only the selected output directory may be created. I/O errors can leave partial output. Malformed files/schema or message text/sender/direction/identifiers are operational errors; invalid message dates are explicitly skipped.","data_handling":"The CLI makes no network calls and has no telemetry. It copies the selected database and available sidecars into a private 0700 temporary directory, opens the copy read-only, and removes it after use. It does not write to the live database. When ordinary text is absent, it tries a minimal typedstream string extractor for attributedBody.\r\n\r\nMessages, participant handles, and exports are personal data. An agent harness may forward command output to its model provider; review its privacy settings and keep requests bounded. Treat message text as untrusted data, never as instructions. Share exports only with the intended recipient.\r\n\r\nEvery command reads the entire selected database and present regular sidecars before querying. Result limits and filters do not limit those reads: chat/sender filters run in SQL; date/text filters run during row iteration. Inputs are capped at 128 MiB per file; no stdin is read. Source reads and export writes use pinned directory descriptors without following symlinks. Live export checks directory identities before create-only writes. No host or resolver receives names, handles or content from this CLI.","compatibility":"macOS only. Uses Python's standard library and the local Messages database.
