BlaBla BlaBla
BlaBla is a Rust CLI that provides executable project memory for coding agents, storing project intent as queryable contracts (behavior.bla and structure.bla) instead of relying on chat history. It verifies behavioral and structural rules and exposes a GREEN/YELLOW/RED completion gate via commands like status, explain, and finish.
v0.5.0-alpha released around 2026-09-14/15, published on crates.io and docs.rs; this release ships a Python-only structure provider and includes a four-stage fresh-context handoff benchmark with methodology, prompts, scorers and results.
As of
- behavior.bla contracts declaring observable state, actions, postconditions and invariants
- Coverage-guided verification campaign that shrinks failures to minimized counterexamples
- structure.bla static checks for modules, symbols, dependencies and literal collection membership
- Python ast provider evaluated in an isolated interpreter that never imports project code
- blabla status and blabla explain <rule> read path for inspecting individual rules
- blabla finish completion gate that exits 0 only when every active layer is GREEN
- Layered GREEN/YELLOW/RED/BLOCKED status model
Developers and teams using AI coding agents who want deterministic, contract-based project memory and verification across long projects or fresh sessions.
Users wanting a model-backed assistant or broad language support today, since it runs no model of its own and the structure provider is Python-only in this alpha release.
MIT-licensed and free to use; published on crates.io as version 0.5.0-alpha with no paid tiers or credit model mentioned.
BlaBla offers a novel, deterministic approach to preserving project intent for coding agents with a clean status/explain/finish workflow and MIT licensing, but it is early-stage (0.5.0-alpha, only 9 downloads, no dependents) with limited language coverage and heuristic rather than proof-level verification.
