Your AI coding agent just confidently edited the wrong file. Your research agent cited a retracted paper twice. Your customer-service bot quoted a policy from 2023. None of these are model failures. They're all context failures.Introducing Pratyakṣa, an open-source context engineering harness that fixes how AI agents manage what they know, why they know it, and when to stop trusting it.Here's what makes it genuinely different:🔹 Ancient wisdom meets modern AI — The design vocabulary comes from classical Indian epistemology (Nyāya, Advaita Vedānta, Sāṃkhya). A 14th-century logician's framework for what counts as valid knowledge turned out to be the missing operating manual for AI agents.🔹 Sublation, not deletion — When a newer, more authoritative source supersedes an older one, the old fact is retired, not erased. The audit trail stays intact. Every decision is replayable.🔹 Separation of attention & judgement — Two sub-agents, Manas (selects evidence) and Buddhi (judges and responds), ensure these are never confused — the source of a whole class of hallucinations.🔹 Results that hold up — Across 7 benchmarks (RULER, HELMET, SWE-bench, HaluEval, TruthfulQA and more), the harness beats unaided baselines at p ≤ 0.002. On a 720-pair head-to-head, it anchored on the correct file 720/720 times. The unaided baseline? Coin-flip rate — 50.3%.🔹 Installs in 30 seconds — Works in Cursor, Claude Code, and Claude Desktop. No fine-tuning, no architecture changes. Just two commands.🔌 Plugin (install & use) https://github.com/SharathSPhD/pratyaksha-context-eng-harness📁 Full harness, experiments & validation (GitHub) https://github.com/SharathSPhD/context-engineering-harness📄 Citable preprint — Zenodo (DOI-backed canonical v2.0) https://zenodo.org/records/19653013🚀 v2.1.1 Release page (plugin zip, figures, checksums) https://github.com/SharathSPhD/pratyaksha-context-eng-harness/releases/tag/v2.1.1🗺️ Project status canvas https://sharathsphd.github.io/context-engineering-harness/canvas.html📰 Full article (Substack) https://open.substack.com/pub/technektar/p/when-the-context-window-is-big-and
