4//! `oo` (double-o) — a context-efficient command runner for AI coding agents.
5//!
6//! This library helps AI agents run shell commands efficiently by classifying output
7//! and reducing context usage. Commands are executed, their output is analyzed, and
8//! results are compressed using pattern matching and intelligent categorization.
9//!
10//! # Core Concepts
11//!
12//! - **Classification**: Commands are categorized into four tiers based on success/failure
13//!   and output size. Small successful outputs pass through verbatim, while large outputs
14//!   are pattern-matched to extract terse summaries or indexed for later recall.
15//! - **Patterns**: Regular expressions define how to extract summaries from command output.
16//!   Built-in patterns exist for common tools (pytest, cargo test, npm test, etc.).
17//!   Custom patterns can be loaded from project-local `<git-root>/.oo/patterns/` or
18//!   user-global TOML files in the user patterns directory (project patterns take precedence).
19//! - **Storage**: Large unpatterned outputs are stored in a searchable database (SQLite by
20//!   default, with optional Vipune semantic search). Stored outputs can be recalled with
21//!   full-text search.
22//! - **Categories**: Commands are auto-detected as Status (tests, builds, linters),
23//!   Content (git show, diff, cat), Data (git log, ls, gh), or Unknown. This determines
24//!   default behavior when no pattern matches.
25//!
26//! # Example
27//!
28//! ```
29//! use double_o::{classify, Classification, CommandOutput, Pattern};
30//! use double_o::pattern::builtins;
31//!
32//! // Run a command
33//! let args = vec!["echo".into(), "hello".into()];
34//! let output = double_o::exec::run(&args).unwrap();
35//!
36//! // Classify the output
37//! let command = "echo hello";
38//! let patterns = builtins(); // or load_user_patterns(&path)
39//! let result = classify(&output, command, &patterns);
40//!
41//! match result {
42//!     Classification::Passthrough { output } => {
43//!         println!("Output: {}", output);
44//!     }
45//!     Classification::Success { label, summary } => {
46//!         println!("✓ {}: {}", label, summary);
47//!     }
48//!     Classification::Failure { label, output, .. } => {
49//!         println!("✗ {}: {}", label, output);
50//!     }
51//!     Classification::Bounded { label, size, .. } => {
52//!         println!("Bounded: {} ({} bytes)", label, size);
53//!     }
54//!     Classification::Large { label, size, .. } => {
55//!         println!("Indexed: {} ({} bytes)", label, size);
56//!     }
57//! }
58//! ```
