fux-answer

What problem does it solve? When you need an answer grounded in your team's written knowledge — runbooks, specs, decisions — with exact line citations and proof the source text is still current, this Skill runs fux answer to read the top-ranked documents from their sources and returns verbatim passages with freshness verdicts, then uses fux verify to reproduce or audit that answer later. ## Core Features & Use Cases - Cited answers with line-range locators: fux answer "<q>" --json --band returns verbatim passages with loc (e.g. docs/mesh.md:L10-L13), the sha of the bytes read, and a confidence band (none, weak, partial, grounded). - Freshness verdicts: each citation is labeled current, stale, as-ingested, cached, or unverified, so you know whether the quoted text still matches what was indexed; --audit shows every document examined. - Receipts and verification: --receipt emits a re-runnable in-toto record, and fux verify receipt.json --rerun --json reports reproduced, drifted:config, drifted:corpus, or unverifiable without ever fetching. - Use Case: Ask "how do we roll back the gateway" and get the exact current lines from the runbook with a sha and freshness verdict, save the receipt, and re-verify it in CI weeks later to confirm nothing drifted. ## Quick Start Ask the assistant to answer your question from the docs with citations by running fux answer with --json and --band, then report each passage with its own locator and freshness verdict.
