BroCode v0.1.43

⚡ Overview

BroCode is an autonomous AI coding agent designed for precision, reliability, and token efficiency. Rather than performing unconstrained file overwrites or speculative edits, BroCode follows a deterministic engineering cycle:

$$\text{Analyze Context} \longrightarrow \text{Plan Architecture} \longrightarrow \text{Locate Symbols} \longrightarrow \text{Apply Resilient Edit} \longrightarrow \text{Verify Build/Tests} \longrightarrow \text{Retain Project Rules}$$

🛡️ Core Engineering Pillars:

1. Targeted Precision: Performs localized, surgical edits without unnecessary full-file rewrites.
2. 5-Tier Resilient Code Editor: Automatically resolves indentation shifts, line trimming, CRLF/LF line endings, and sliding-window fuzzy matching to prevent patch failures.
3. Atomic Git Shadow Tree Rollback: Generates zero-loss Git plumbing snapshots under refs/brocode/snapshots before writing to disk, enabling instant /undo without corrupting working branches.
4. Cryptographic AI Provenance Engine: Tracks every modification with SHA-256 Merkle chains and signed SBOM artifacts to mathematically verify AI authorship via /verify and /trace.
5. Stack-Agnostic Dependency Resolver & Blast Radius: Analyzes project dependencies across Node.js, Go, Python, Rust, PHP, Ruby, and .NET to auto-resolve missing packages and map blast radiuses.
6. Multi-Provider Circuit Breaker & Fallback Router: Automatically fails over to backup models upon rate limits or server errors with cooldown management and vendor isolation.
7. Exact Offline BPE Token Accounting & Auto-Compaction: Native tiktoken-go offline tokenizer ensures deterministic context compaction at 80% capacity with 5-part structured memory preservation.
8. Native LSP & One-Click Auto-Fix: Auto-detects installed language servers (TypeScript, Go, Python, Rust, C/C++, Vue, Svelte) to deliver project-wide diagnostics, code actions, and auto-imports.
