+# CLAUDE.md — nbd
+
+`nbd` is a CLI tool for managing work tickets, primarily targeted at agent workflows. It is an independent Rust crate within the `vibed` mono-repo.

+
+## Tech Stack
+
+- **Language:** Rust (edition 2021)
+- **Async runtime:** `async-std`
+- **CLI parsing:** `clap` (derive feature)
+- **Serialization:** `serde` + `serde_json`
+- **Test utilities:** `tempfile` (dev-dependency)
+
+## Data Model
+
+Tickets are stored as `.json` files in `.nbd/tickets/{id}.json`, where `id` is a 6-character hex string (e.g. `a3f9c2`). The `.nbd/` root is found by traversing up from cwd, like `git` finds `.git/`.
+
+```
+Ticket {
+    id: String                  // 6-char hex
+    title: String
+    body: String
+    priority: u8                // 0..=10, default 5
+    status: Status              // Todo | InProgress | Done, default Todo
+    dependencies: Vec<String>   // Vec of ticket IDs, default []
+    ticket_type: TicketType     // Project | Feature | Task | Bug, default Task
+}
+```
+
+## CLI Interface
+
+```sh
+nbd create --title "..." [--body "..."] [--priority 5] [--status todo]
+           [--type task] [--deps id1,id2] [--json]
+
+nbd read <id> [--json]
+
+nbd list [--json]
+
+nbd update <id> [--title "..."] [--body "..."] [--priority N]
+               [--status ...] [--type ...] [--deps ...] [--json]
+```
+
+`--json` is available on all commands for machine-readable output.
+
+## Module Responsibilities
+
+| Module | Responsibility |
+|---|---|
+| `main.rs` | `clap` CLI definition and subcommand dispatch only |
+| `ticket.rs` | `Ticket` struct, enums, ID generation, validation |
+| `store.rs` | directory traversal, file read/write, CRUD operations |
+| `display.rs` | tabular formatting and JSON output |
+| `tests.rs` | unit tests for all modules |
+
+## Validation
+
+Run in order from this directory before committing:
+
+```sh
+cargo fmt
+cargo check
+cargo clippy
+cargo test
+```
+
+## Testing
+
+- **Unit tests:** `src/tests.rs` — test each module in isolation; use `tempfile` for any file I/O
+- **Integration tests:** `tests/integration.rs` — test full command flows (create → read → list → update) against a real temp directory; test directory traversal by running from a subdirectory
+
+Target 80%+ code coverage.
+
+## Git Conventions
+
+Follows [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/#summary). Use `nbd` as the scope:
+
+```
+feat(nbd): add list command
+fix(nbd): handle missing .nbd directory gracefully
+test(nbd): add roundtrip serialization test
+```
+
+## Code Style
+
+- All public functions, structs, enums, and modules must have rustdoc comments.
+- Include doc-examples where applicable — these double as doctests.
+- Default `rustfmt` conventions; no custom `rustfmt.toml`.
+
+## Release Builds
+
+```toml
+[profile.release]
+opt-level = "z"
+lto = true
+strip = true
+codegen-units = 1
+```
+
+## License
+
+Dual-licensed under Apache-2.0 and MIT, consistent with the rest of the `vibed` mono-repo.
