1//! # oy
2//!
3//! `oy` adds one concise autonomous agent and repeatable repository audit/review workflows to
4//! [OpenCode 2](https://opencode.ai/). Its current local MCP adapter provides deterministic
5//! repository collection, ordered chunks, target-diff input, and normalized Markdown/SARIF
6//! reports while the project moves toward file-backed CLI evidence. OpenCode remains responsible
7//! for model execution, providers, authenticated sessions, permissions, and general coding tools.
8//! oy does not store provider credentials.
9//!
10//! ## Start with the CLI
11//!
12//! The command-line interface is the supported automation surface:
13//!
14//! ```text
15//! oy setup --dry-run       # preview package/config migration
16//! oy setup                 # register the version-matched OpenCode package
17//! oy audit                 # write ISSUES.md
18//! oy review main           # write REVIEW.md for git diff main
19//! oy enhance <finding-id>  # remediate one reported finding
20//! ```
21//!
22//! See the [getting-started guide](https://oy.adonm.dev/getting-started.html),
23//! [workflow guide](https://oy.adonm.dev/workflows.html), and
24//! [CLI/MCP reference](https://oy.adonm.dev/reference.html) for the user-facing
25//! contract.
26//!
27//! ## Determinism boundary
28//!
29//! Input collection, ordering, limits, and report rendering are deterministic. Findings are
30//! produced by the model selected in opencode and are not deterministic. The collector also
31//! has documented exclusions; “all chunks” does not mean every byte in a repository.
32//!
33//! ## Rust API
34//!
35//! This crate exists primarily to keep the `oy` binary entrypoint small. [`run`] and
36//! [`err_line`] are public for that entrypoint and lightweight embedding, but spawning the
37//! `oy` executable is preferred for automation. Other modules and implementation details are
38//! private and may change without a semver-stable library API commitment.
39//!
40//! ```no_run
41//! # async fn example() -> anyhow::Result<()> {
42//! // Arguments exclude the executable name, just like std::env::args().skip(1).
43//! let exit_code = oy::run(vec!["doctor".into(), "--json".into()]).await?;
44//! assert_eq!(exit_code, 0);
45//! # Ok(())
46//! # }
47//! ```
