 ## What `trellis mem` is
 
-A local CLI that indexes the user's past Claude Code, Codex, Pi Agent, and ZCode conversation logs and lets you list, search, slice by Trellis task boundaries, and dump cleaned dialogue from them. Claude and Codex use `~/.claude/projects/` and `~/.codex/sessions/`. Pi uses its default or environment-configured session root, global `~/.pi/agent/settings.json`, and the scoped project's `.pi/settings.json`; relative `sessionDir` values resolve from the settings file directory. Project-local Pi settings require project-scoped lookup through the current cwd or `--cwd`. ZCode uses `~/.zcode/cli/db/db.sqlite`. OpenCode logs are not yet indexable (provider adapter pending) — when an OpenCode session is the obvious target, surface that limitation rather than guessing.

 ## Caveats
 
 - **OpenCode adapter is a stub on `0.6.0-beta.*`.** When `--platform` resolves to OpenCode (or `all` and OpenCode would be included), `mem` prints a one-line "reader unavailable" notice and continues with the other platforms. Don't promise OpenCode coverage in your reply until the adapter ships.
+- **`--platform devin` is Cognition Devin CLI** (`~/.local/share/devin/cli/sessions.db`). It is not `trellis init --devin` (Devin Desktop / Cascade) and not Factory Droid.
 - **`--phase` slicing depends on `task.py create` / `task.py start` invocations appearing in the recorded bash calls of the session.** Sessions where the user ran `task.py` from a different terminal — outside the recorded AI loop — will not have phase boundaries. `--phase all` is the safe fallback.
 - **`mem` indexes platform JSONL files directly.** If the user has cleared their Claude / Codex / Pi session storage, `mem` cannot recover what is no longer on disk.
 - **`mem` is read-only.** No remote sync, no edits to platform JSONL. Any write you do based on `mem` findings is your own follow-up call into the editing tools available to you.
