Guides

• Install ajq — get ajq onto your machine and provision local assets.
• Make ajq available to a coding agent — add a project decision rule so agents choose ajq for semantic JSON work before writing a script.
• Process an NDJSON stream — handle newline-delimited JSON and raw log lines.
• Filter JSON by meaning — find records by topic or intent with explicit semantic predicates.
• Classify JSON and NDJSON streams — route records into a fixed set of semantic labels.
• Use ajq safely from coding agents — start with mock and --explain, then cap and observe real model calls.
• Install the ajq coding-agent skill — add the native Codex marketplace or the optional Claude Code and Cursor adapter.
• Use ajq with other data formats — pipe JSON from complementary jq ecosystem adapters into ajq.
• Write a semantic filter — use fuzzy =~ predicates and bounded semantic functions.
• Estimate model calls before running — use --explain to budget cost and latency.
• Use cloud backends — run semantic queries with Anthropic, OpenAI, or OpenRouter.
• Control semantic costs — combine --explain, --max-calls, and --stats.
• Manage the judgement cache — inspect, bypass, and clear cached semantic judgements.
• Configure defaults — set backend, model, base URL, cost cap, and cache defaults.
• Use a larger local model — pull and select a larger pinned GGUF model.
