Nautilus-Compass v1.1.0 Ships Recall-Consumption Fix
The author released nautilus-compass v1.1.0, a technical update to their agent memory system that addresses a class of failures where recalled memory items were surfaced but not actually consumed by LLM agents. The release implements a three-layer fix: (v0) embed the first ~800 characters of body text in the top-3 recall hits, (v1) include past-mistake bodies inside 'anti-anchor' drift alerts, and (v2) introduce recall_consumption.py to detect recall-fired-but-not-consumed signatures by checking session logs for subsequent Read tool calls. The release also extends governance tooling (governance_plan MCP tool) to route phases via platform registries (agents_capabilities.json and anchor_packs_phases.json). The repo provides pip/npm packages, links to demos and two arXiv papers, and retains prior evaluation numbers while improving consumption behavior in live sessions.
A targeted technical release that improves reliability of LLM agent memory usage by making recalled rules visible and auditable; useful to developers building conversational agents but not a major industry-wide platform change.

Key Takeaways & Evidence Grounding
- Released nautilus-compass v1.1.0, published 2026-06-07.
- v1.1.0 implements a three-layer fix to 'recall consumption drift' (embed bodies in top hits; embed past-mistake bodies in anti-anchor alerts; detect unconsumed recalls with recall_consumption.py).
- New module recall_consumption.py inspects session jsonl to detect recall hits that were surfaced but not Read by the agent; wired into drift_check MCP tool and a mid_session_hook.
- Governance changes: governance_plan MCP tool now reads _platform_registry/agents_capabilities.json and _platform_registry/anchor_packs_phases.json to route decomposition phases without template code changes.
- Installable via pip/npm (nautilus-compass==1.1.0 / nautilus-compass@1.1.0); repository and demo links provided; two arXiv papers accompany the release and 228 pytests pass.

Nautilus‑Compass v1.1.0 Fixes Memory Recall Consumption Drift
The maintainer of nautilus‑compass published v1.1.0 (June 5, 2026), addressing a class of failures where agent recall surfaced relevant memory metadata but agents did not consume the referenced file bodies. v1.1.0 implements a three-layer fix: embedding the first 800 characters of body text in top recall hits, including lesson bodies in anti‑anchor drift alerts, and a new recall_consumption.py module that detects 'recall fired but not consumed' by scanning session logs. The release also extends the V7 governance plan with a governance_plan MCP tool that routes decomposition phases using platform registries. The package is available via pip and npm, the repo and demo are public, two arXiv papers accompany the work, and the release ran 228 pytests with MIT anchors CC0.
claude-recall lets AI agents read session archives
A developer built claude-recall, a beta tool that lets Claude Code instances (and similar agentic tools) read and reuse their locally persisted session history. The tool indexes Claude Code's per-turn JSONL archive into a local SQLite database with FTS5 full‑text search, offers an optional semantic reranking layer using a local Ollama embedding model (nomic-embed-text), and injects ranked past-session matches into prompts via a UserPromptSubmit hook. The hook is distributed as a NativeAOT-compiled binary to avoid Python startup latency. The package (v0.5.3) is on PyPI and the open repo is on GitHub under an MIT license. The author frames this work as part of a broader pattern—agents already write structured histories to disk but rarely read them—and contrasts claude-recall’s read-only approach with other memory strategies like curated remember/forget systems and task-tracking stores.
AI News: 1M Context, Memory Limits, Agent Infrastructure
This AINews roundup covers multiple AI product and research developments: Replit reportedly tripled to a $9B valuation and launched Replit Agent 4, a collaborative multi-agent canvas for apps, sites, and slides. NVIDIA released Nemotron 3 Super, an open 120B / ~12B-active model with a 1M-token context, hybrid Mamba‑Transformer/SSM Latent MoE architecture, and inference optimizations (including multi-token prediction) claiming up to ~2.2x faster inference versus gpt-oss-120B. The piece traces a broader 2026 trend from coding agents to general knowledge-work agents and highlights launches such as Perplexity’s Personal Computer, Base44 Superagents, and LangChain updates. It also reports Anthropic creating The Anthropic Institute (Jack Clark as Head of Public Benefit) and notes an operational outage affecting Claude/Claude Code. Research and benchmarks covered include agent evaluation work, retrieval/post‑training advances, Google Gemini Embedding 2, Qwen3.5 architecture notes, and device/benchmark reports (M5 Max).
