Package aisync mirrors a Claude Code session's TodoWrite list into the nt store (SPEC §8, §10).

Package cli implements nt's command-line interface.

Package config loads nt's optional config file, $NT_DIR/config.toml.

Package dateparse parses the human date and priority inputs nt accepts on the CLI and in the TUI (SPEC §7.3), kept in one place so both surfaces agree.

Package links implements the unified cross-item linking model (SPEC §5.1): a single [[target]] syntax that resolves to a note (by slug, title, or id) or a task (by ULID / short prefix), plus backlinks computed on demand by scanning files — no stored index.

Package lock provides an advisory file lock around the critical section that mutates tasks.txt (SPEC §6.4).

Package mcp serves nt over the Model Context Protocol (stdio, JSON-RPC 2.0), so an agent uses typed tools (nt_ready, nt_add, …) instead of constructing CLI shell strings.

Package mutate is the single ULID-keyed mutation engine shared by the CLI and (later) the TUI, implementing the write contract from SPEC §6.1–6.3.

Package note implements nt's markdown notes with light YAML frontmatter (SPEC §5).

Package quickadd normalizes the natural-language conventions people type into a task's text — across the CLI, TUI, web, and MCP add paths — so they all behave identically.

Package search implements files-only search (SPEC §7.1): ripgrep when a real rg binary is on PATH, otherwise a built-in walker.

Package store resolves the nt data directory ($NT_DIR) and the paths of the files within it.

Package task implements nt's todo.txt task model with the lossless round-trip guarantee from SPEC §4: a file is parsed into an ordered list of nodes (each a parsed task or a preserved raw line), and an unmodified line is re-emitted byte-for-byte.

Package tui implements nt's terminal UI (SPEC §12) with Bubble Tea.

Package ulid generates ULIDs (Universally Unique Lexicographically Sortable IDs) with zero external dependencies.

Package undo implements the append-only transaction journal from SPEC §6.3.

Package view persists named "smart views" — saved bundles of the `nt list` filter so a user can capture a query once and recall it by name (T4).

Package web is the HTTP adapter: a localhost notes viewer (`nt web`).
