Adaptive Agent Harness v0.3.0a0 — First Public Alpha

Give agents a workbench — not just a bigger prompt.

This is the first public source release of Adaptive Agent Harness: a host-neutral foundation for bounded Recursive Language Model (RLM) jobs, persistent IPython workspaces, durable operation receipts, and MCP-based agent integration.

Why it matters

RLMs treat long context as data that a model can inspect, transform, decompose, and recursively query. IPython gives that process a persistent computational working set. Adaptive Agent Harness adds the lifecycle layer around both: explicit budgets, grants, operation handles, receipts, artifacts, recovery policy, and host-owned authority.

Highlights

  • bounded, persisted RLM jobs with brokered model/subagent/evidence calls;
  • persistent plain-Python and IPython workspaces with NumPy and pandas;
  • 30-tool MCP v7 surface;
  • durable supervisor with replaceable authenticated frontends;
  • exact process-start identity and generation/lease fencing;
  • cursor-readable status, events, cancellation, and reconciliation;
  • schema v5 policy-bound RLM, checkpoint, and effect-receipt recovery contracts;
  • digest-bound artifacts and adaptive-asset bundles;
  • Codex and Hermes host profiles with v0.3 cache-busters for the current 30-tool surface;
  • English marketing-first README plus 17 linked translations.

Verification

The public source candidate reproduced:

  • 245 passed, 1 platform-gated skip in the full repository suite;
  • Python 3.11–3.14 coverage;
  • a clean exact-wheel Linux/WSL supervisor/frontend probe;
  • additive v3-to-v4-to-v5 migration and older-reader fail-closed checks;
  • frontend replacement, supervisor loss, stale-writer, single-owner, authoritative-receipt reuse, and durable RLM scenarios.

The public staging tree was rebuilt and retested before publication. Earlier native-Windows and
installed-Hermes rows in HOST-COMPATIBILITY.md and WAL.md are maintainer-reported historical
context: their supporting host receipts are not committed here and are not independently auditable
from this repository.

Important alpha boundaries

  • This is not a security sandbox.
  • RLM jobs and IPython workspaces are sibling surfaces; they do not share state or execute inside one another automatically.
  • The runtime does not own provider credentials, general external effects, or final delivery.
  • It does not promise universal exactly-once semantics.
  • Broad automatic IPython state restoration remains in progress.
  • Stable API compatibility and package-registry publication are not yet promised.

This GitHub release publishes source archives generated by GitHub. No standalone wheel is attached; the independently verified cutover wheel and the public documentation commit are distinct artifacts.
