1//! # CVKG Agentic Development Guidelines (v1.2)
2//!
3//! All AI agents contributing to this crate MUST follow ALL seven rules:
4//!
5//! ── Karpathy Guidelines (1–4) ────────────────────────────────────────────
6//! 1. THINK FIRST     -- State assumptions. Surface ambiguity. Push back on complexity.
7//! 2. STAY SIMPLE     -- Minimum code. No speculative features. No unasked-for abstractions.
8//! 3. BE SURGICAL     -- Touch only what's required. Own your orphans. Don't improve neighbors.
9//! 4. VERIFY GOALS    -- Turn tasks into checkable criteria. Loop until they pass. Never commit broken.
10//!
11//! ── CVKG Extended Protocols (5–7) ────────────────────────────────────────
12//! 5. TRIPLE-PASS     -- Read the target, its surrounding context, and its full call graph
13//!                      at least THREE TIMES before making any edit or revision.
14//! 6. COMMENT ALL     -- Every major pub fn, unsafe block, and non-trivial algorithm in
15//!                      every .rs/.ts/.h/.wgsl file MUST have a descriptive doc comment.
16//!                      Comments describe WHY and WHAT CONTRACT, not HOW mechanically.
17//! 7. MONITOR LOOPS   -- Check every tool call / command for progress every 30 seconds.
18//!                      After 3 consecutive identical failures, stop, write BLOCKED.md,
19//!                      and move to unblocked work. Never silently accept a broken state.
