Atomic Agents Files

What's New in v2.8.0

A feature release adding new Forge tools, a pluggable system-prompt base class, automatic context-window trimming, and a rewritten Claude plugin — plus the multi-agent deep-research example.

Core framework

Features

• BaseSystemPromptGenerator — new abstract base class so you can build custom system-prompt generators; SystemPromptGenerator now subclasses it (fully backwards compatible).
• Automatic context trimming — AtomicAgent gains max_context_tokens to auto-trim history and prevent context-window overruns.

Bug Fixes

• Prevent None in MCP prompt text extraction from causing a str.join TypeError (#252).

Atomic Forge — new tools

• arxiv_search — academic paper search via the public arXiv API
• datetime_tool — timezone-aware now / parse / convert / shift / diff
• hackernews_search — Hacker News search via the free Algolia API
• pdf_reader — PDF text + metadata extraction (local file or URL, page-range support)
• weather — current conditions and daily/hourly forecast via Open-Meteo (no key)
• wikipedia_search — Wikipedia search in any language edition (no key)
• fia_signals — crypto market intelligence (regime, signals, yields, gas, trending, wallet risk)

Tooling & examples

• Claude plugin v2 — rewritten as a skills-only pack with create-atomic-* skills (agent, tool, schema, context-provider) and an atomic-explorer subagent for codebase mapping; fewer atomic-reviewer false positives.
• deep-research example — rebuilt as a proper multi-agent research pipeline (planner, decider, extractor, reflector, writer, QA) with a restored chat loop.
• docs — clarified tool philosophy and the two patterns for using tools.
