Agent Farm v3.4 - Chunked Write Edition

AI organism evolution and parallel task execution with tool-enabled agents. Now with Chunked Write Pattern for generating large documents and code files!

What's New in v3.4

  • Chunked Write Pattern: Bugs write sections in parallel, Python assembles directly

  • chunked_write: Generate large markdown/text documents (unlimited size)

  • chunked_code_gen: Generate multi-function code files in parallel

  • chunked_analysis: Multi-perspective analysis with synthesis

  • Bypasses 500-char limit: Each bug writes small chunks, combined output is unlimited

Performance

  • 8.6x faster than v3.0 (103s -> 12s for 4-task swarm)

  • 1 iteration per task (was 3-5)

  • 100% success rate with real tool data

  • Local synthesis - qwen2.5:14b synthesizes results (no cloud tokens!)

Structured Output Details

Agent Farm v3.3 uses Ollama's structured output feature to enforce JSON schemas on model responses:

# Bug responds with guaranteed-valid JSON: {"tool": "system_status", "arg": ""} {"tool": "exec_cmd", "arg": "df -h"} {"tool": "check_service", "arg": "ollama"}

The constrained decoding (GBNF grammar) masks invalid tokens during generation, ensuring:

  • Always valid JSON

  • Correct tool names

  • Proper argument structure

  • No parsing failures

Results now include a mode field showing which method was used:

  • structured - JSON schema enforced

  • structured+autoformat - JSON + simple result formatting

  • structured+deep - JSON with multi-step reasoning

  • regex - Fallback regex parsing

  • regex+autoformat - Regex + simple result formatting

Chunked Write Pattern

The chunked write pattern solves the ~500 char output limitation of small models by decomposing large tasks:

1. PLANNER BUG (qwen2.5:14b) |-- Creates structured JSON outline |-- {"sections": [{"title": "...", "description": "..."}]} 2. WORKER BUGS (qwen3:4b) - IN PARALLEL |-- Each writes one section (~300-500 chars) |-- 4 workers = 4 sections simultaneously 3. PYTHON CONCATENATION (NO LLM) |-- header + separator.join(sections) |-- Zero token cost, instant assembly 4. DIRECT FILE WRITE (NO LLM) |-- tool_write_file() saves result |-- Bypasses any output corruption

Why It Works

  • Small models excel at focused, short outputs

  • Each section is within the "safe zone" (<500 chars)

  • Python handles assembly (no LLM token cost)

  • Parallel execution via ThreadPoolExecutor

  • Structured output ensures reliable planning

Usage Examples

System Health Check

agent-farm:system_health_swarm

Custom Task Swarm

agent-farm:tool_swarm colony_type: "heavy" tasks: [ {"prompt": "Check CPU temperature"}, {"prompt": "List top 5 memory processes"}, {"prompt": "Check if docker is running"} ]

Large File Write (Direct)

agent-farm:heavy_write path: "/tmp/large_output.txt" content: "... large content ..."

Codebase Reconnaissance

agent-farm:recon_swarm target_path: "/home/kyle/repos/my-project"

Generate Large Document (Chunked)

agent-farm:chunked_write output_path: "/tmp/security_guide.md" spec: "Linux server security hardening guide" num_sections: 5 doc_type: "markdown"

Output: 9KB+ document with 5 coherent sections

Generate Code File (Chunked)

agent-farm:chunked_code_gen output_path: "/tmp/utils.py" spec: "File utilities: read, write, copy, delete" language: "python" num_functions: 4

Output: Complete Python module with 4 functions

Multi-Perspective Analysis

agent-farm:chunked_analysis target: "/home/kyle/repos/project" question: "What are the architectural patterns?" num_perspectives: 4

Output: Analysis from Structure, Patterns, Quality, Performance perspectives

Installation

cd ~/repos/agent-farm uv venv uv pip install -e .
