- **Text-only by contract** — backends reject binary/non-UTF-8 content with `FS_NOT_TEXT`; binary-safe operations are a deliberate deferral of [the tool-schemas RFC](../../../docs/rfc/implemented/feature/2026-06-17-filesystem-tool-schemas.md).
- **Seven primitives only** — no delete, rename/move, copy, or watch; `listDir` is single-level, with recursion, globbing, pagination, and search out of scope per [the directory-listing RFC](../../../docs/rfc/implemented/architecture/2026-07-03-filesystem-directory-listing-seam.md).
- **`listDir` has no in-repo consumer yet** — skill discovery and a model-facing `ls` tool are the named follow-ups; sessions list directories via `bash` meanwhile.
- **No IO deadline** — the seam arms no timeout; cancellation is a best-effort optional `AbortSignal` per primitive (the deliberate [fs-family stance](../README.md)).
- **Resolve-then-operate costs a remote backend two round-trips per tool call** — folding or caching resolution is left to such a backend.

## Known Limitations and Deferred Work
- **No directory-listing, glob, grep, or search tools ship** — a deferral of [the tool-schemas RFC](../../../docs/rfc/implemented/feature/2026-06-17-filesystem-tool-schemas.md) (and `ctx.fs.listDir` has no tool consumer yet); models fall back to `bash`.
- **No directory-listing, glob, grep, or search tools ship** — a deferral of [the tool-schemas RFC](../../../docs/rfc/implemented/feature/2026-06-17-filesystem-tool-schemas.md); `ctx.fs.listDir` serves provider code such as skill discovery but still has no model-facing consumer, so models fall back to `bash`.
- **`read` handles UTF-8 text files only** — binary-safe reads and PDF/image/multimodal content are deferred; a directory target is `FS_NOT_REGULAR_FILE`.
- **No timeout surface** — `read`/`write`/`edit` take no timeout argument and declare no `timeout-policy` budget; cancellation rides `exec.signal` only (the deliberate [fs-family stance](../README.md)).
