fux

What problem does it solve? Agent-assisted projects repeatedly re-derive business rules, conventions, and cross-session memory from scratch each session. This Skill stores each fact once as a frontmatter entry in a .fux/ directory and serves it back through a generated index, graph, and memory views, with deterministic maintenance commands that cost nothing in LLM calls. ## Core Features & Use Cases - Unified knowledge substrate: Rules, glossary, ADRs, memory, and narrative docs live in one frontmatter format, with INDEX.md, rules.json, and graph views regenerated by fux build. - Drift detection and validation: fux check flags dead code references, stale rules, and conflicts; fux verify runs invariant assertions so rules that drift from code fail rather than warn. - Deterministic retrieval and governance: fux recall retrieves relevant rules by keyword, fux ratify records tamper-evident rule approvals, and fux gate enforces knowledge health in CI or pre-commit hooks. - Use Case: A team documenting why a pricing formula works a certain way creates a formula rule with code_refs pointing at the implementation lines; later sessions answer questions via fux recall instead of re-reading the codebase. ## Quick Start Ask the agent to run /fux init in your project to scaffold the .fux knowledge directory, then use /fux recall followed by your question to retrieve the relevant rules.
