Axocoatl runs persistent AI agents that coordinate through a **stigmergic event
lattice** — agents activate when their dependencies complete, driven by
pheromone-style signals with no central orchestrator. Built in Rust on the
`ractor` actor model: low memory, fast cold start, provider-agnostic.

## 60-second quickstart

```bash
# 1. Install (no Rust toolchain required)
curl -fsSL https://raw.githubusercontent.com/axocoatl/axocoatl/main/scripts/install.sh | sh

# 2. Interactive setup wizard — picks a provider, scaffolds a project
axocoatl onboard

# 3. Check your environment
axocoatl doctor

# 4. Start the daemon + API, then chat
axocoatl dev
axocoatl chat -a assistant
```

Prefer Cargo? `cargo install axocoatl-cli` (requires Rust 1.82+).

> **Skipping `onboard`?** Copy [`axocoatl.example.yaml`](axocoatl.example.yaml)
> to `axocoatl.yaml` — two agents and one workflow, fits on one screen.
> The full `axocoatl.yaml` shipped in the repo is the larger demo (12 agents,
> scheduled runs, MCP servers).

## Why Axocoatl

| Capability | Axocoatl | AutoAgents | CrewAI |
|---|:--:|:--:|:--:|
| Language / runtime | Rust / actors | Rust / actors | Python |
| **Stigmergic coordination** (no orchestrator) | ✅ | ❌ | ❌ |
| HTN symbolic planning | ✅ | ❌ | ❌ |
| Auction-based agent selection | ✅ | ❌ | ❌ |
| Per-agent token budgets | ✅ | ❌ | partial |
| 4-tier persistent memory + checkpointing | ✅ | partial | partial |
| MCP client + server | ✅ | partial | ✅ |
| A2A protocol | ✅ | ❌ | ❌ |
| Provider-agnostic (Ollama/OpenAI/Anthropic/…) | ✅ | ✅ | ✅ |
| Interactive onboarding + `doctor` | ✅ | ❌ | ❌ |

The differentiator is the **coordination layer**: define agents with
`depends_on`, and the event lattice cascades work through them automatically.

```yaml
agents:
  - id: researcher
    provider: ollama
    model: llama3.2
    depends_on: []
  - id: summarizer
    provider: ollama
    model: llama3.2
    depends_on: [researcher]   # activates when researcher completes

workflows:
  - id: research-and-summarize
    agents: [researcher, summarizer]
    entry_point: researcher
```

```bash
axocoatl workflow run research-and-summarize -i "What is photosynthesis?"
```

## Core concepts

- **Agents** — persistent `ractor` actors with a provider, tools, 4-tier
  memory, and a token budget. Survive restarts via checkpointing.
- **Hybrid memory recall** — relevant past exchanges are injected each turn, and
  the agent can also pull on demand: `recall_search` (semantic search over past
  sessions) and `recall_timeframe` (read a day's activity log). Tunable per agent.
- **Agent-managed core memory** — editable blocks (`persona`, `human`, `project`,
  …) the agent curates via tools and that render into its prompt each turn (the
  MemGPT/Letta model). Per-agent by default, shareable across agents. A
  background "sleep-time" pass consolidates idle agents' memory automatically.
- **Stigmergic coordination** — agents publish `TaskCompleted` events; an
  `EventLattice` accumulates pheromone signals and activates downstream agents
  when thresholds are crossed. No scheduler, no glue code.
- **Coordinator role** — for explicit hierarchical work, an agent with
  `role: coordinator` decomposes a goal into subtasks (HTN or LLM), auctions them
  to worker agents, runs them in parallel, and synthesizes the results. The pass
  is resumable via checkpointing.
- **Workflows** — declarative multi-agent DAGs via `depends_on` / `entry_point`.
- **Providers** — Ollama, OpenAI, Anthropic, Mistral, Gemini, OpenRouter. No lock-in.
- **Protocols** — MCP (consume & expose tools) and A2A (agent interop).

quick reference.

## Roadmap

- **Stronger sandbox isolation tiers** — the shipped sandbox is a hardened
  rootless Podman container (capabilities dropped, no-new-privileges,
  network-isolatable); microVM-class isolation (Firecracker) is planned.
