A bulleted imperative like {match} tells the agent to never reveal, disclose, or mention something to the user. Used adversarially it can instruct the agent to hide its tool calls or lie about what it did — stripping the transparency a user relies on to trust the agent.

Recent milestones: v1.3 — Hardened SQLite control plane (May 2026) · v1.4 — MAF synthesis & hybrid runtime strategy (May 31, 2026) · v1.5 — CLI Agents major update (June 2026)
Replaced fragile markdown-based state with a transactional SQLite control plane (state_engine.py), added strong process sandboxing (sandbox_runner.py), HMAC-signed envelopes, approval gating, and WAL concurrency safety. Implementation is stdlib-only (sqlite3, hmac, hashlib, subprocess, os, secrets) — no framework dependencies. This made the custom Python kernel production-grade and laid the foundation for the v1.4 hybrid strategy.
After extensive MAF research and 12 hands-on C# experiments (including full loading of real exploration-cycle-plugin manifests), we pivoted from "do not adopt MAF" to a hybrid architecture:
Manifest-first. Multiple certified runtime adapters second.
Key outcomes:
.md agent manifests and SKILL.md files remain fully portableThis hybrid approach gives us the best of both worlds: battle-tested custom safety primitives + selective leverage of Microsoft's well-engineered patterns.

All plugins deploy to the single `.agents/` folder standard — no duplicate copies needed for `.github`, `.gemini`, `.agent`, etc.

Quick install (all plugins):

This repository is built on a pragmatic acceptance of the current AI engineering landscape: the ecosystem changes weekly, and workflows that were revolutionary six months ago are obsolete today.
Frameworks like agent-agentic-os and spec-kitty are treated as Transitional Architectures — bridges between what agents need to do today and what native SDKs will eventually handle. When Anthropic, Google, and GitHub harden native memory persistence, execution safety, and multi-agent orchestration, large swaths of this tooling will be happily discarded.
The MAF research (May 2026) reinforced this view: instead of choosing between a custom kernel and a framework, we now deliberately pursue a hybrid model:
.md manifests and SKILL.md files remain the source of truth across all runtimesSkills are Applications; the SDK is the OS. Individual skills must function in complete isolation — no hard dependencies on sibling plugins, no assumptions about which framework is running.
agent-agentic-os)The OS implements an eval-gated improvement pipeline for autonomous skill evolution:
os-architect ← intent classifier + ecosystem router
↓
os-improvement-loop ← learning engine: orchestrates multi-iteration improvement
↓
os-eval-runner ← inner gate: KEEP/DISCARD per iteration (evaluate.py)
↓
os-eval-backport ← human gate: review before lab winner → production
↓
os-experiment-log ← scientific backbone: longitudinal tracking + synthesisEntry point: /os-architect — describe what you want in plain language. The agent classifies intent, audits the ecosystem, proposes Path A/B/C, and dispatches via your available CLI tools. os-evolution-planner writes the task plan + delegation prompt. os-architect-tester validates after any changes.
Skills that score HIGH on the autoresearch viability rubric (objectivity + speed + frequency + utility) can run fully autonomous self-improvement loops:
mutate SKILL.md → evaluate.py → exit 0 (KEEP) or exit 1 (DISCARD) → repeatNot all skills are good candidates — use eval-autoresearch-fit to score a skill before running a loop.
Live example — `convert-mermaid` skill, 26 iterations across 2 rounds: 0.61 → 1.00
convert-mermaid eval progress
Each blue diamond is a baseline anchor (one per session). Green = new best score. Amber = kept but not a record. The two-segment shape shows a fresh re-baseline for round 2.

Each plugin works standalone (Mode A) or combined for full Super-RAG power. Init agents detect what is installed in .agents/skills/ and configure only the available layers.
All shared scripts live once at plugins/<plugin>/scripts/. Skills reference them via file-level symlinks (skills/<skill>/scripts/script.py → ../../../scripts/script.py). Directory-level symlinks are forbidden — npx drops them on install.
