CodeEvolve

Evaluate how a codebase evolves from git history — taxonomy & phylogeny, Lehman/ecological signals, technical debt, ranked failure points, a provenance ledger for deliberation, a drafted repository report, and an evidence-linked refactor plan.

GitHub URL | local path
    → taxonomy + clade allocation
    → genetics (lineage, gene flow) + ecology (stages, Lehman proxies)
    → metrics + debt + weaknesses
    → provenance ledger (claim → evidence → falsifier)
    → repo report + refactor plan
    → narrative (heuristic | HF Qwen | cloud)

Install

pip install codeevolve

From source:

git clone https://github.com/ehallford11714/codeevolve.git
cd codeevolve
python -m venv .venv
.\.venv\Scripts\Activate.ps1
pip install -e ".[dev]"
# optional local Qwen:
# pip install -e ".[hf]"

For agents (MCP)

Start here: AGENTS.md · details: docs/MCP.md · objective agent: docs/AGENT.md

pip install codeevolve
# or from source:
pip install -e .
# or from GitHub:
pip install "git+https://github.com/ehallford11714/codeevolve.git"
python -m codeevolve.mcp            # stdio MCP server (also: codeevolve-mcp)

Agents should deliberate from frames (claim → evidence → falsifier), not invent history.

# Native coding agent: propose improvements scored by CodeEvolve
python -m codeevolve --repo . agent --objective reduce_debt --max-rounds 2
python -m codeevolve --repo . agent --objective follow_refactor --apply --verify-cmd "pytest -q"

Quick start

# Default: SLM-guided taxonomy (tier=slm)
python -m codeevolve --repo path\to\repo analyze --out report.json --report-out repo_report.md --refactor-out refactor_plan.md

# Swap up for sharper evolutionary studies
python -m codeevolve --model-tier large --repo path\to\repo analyze
python -m codeevolve tiers

# GitHub URL or owner/repo (cloned under ~/.codeevolve/repos)
python -m codeevolve --repo https://github.com/org/repo analyze --max-commits 300

python -m codeevolve --repo org/repo taxonomy
python -m codeevolve --repo org/repo fatigue
python -m codeevolve --repo org/repo risk
python -m codeevolve --repo org/repo report --md-out repo_report.md
python -m codeevolve --repo org/repo refactor --md-out refactor_plan.md
python -m codeevolve hardware

from codeevolve import CodeEvolve

report = CodeEvolve("https://github.com/org/repo").analyze()
print(report.ecology.global_stage, report.debt.score)
print(report.risk.failure_points[0].title)
print(report.refactor_plan.markdown)

LLM backends (optional)

python -m codeevolve --repo . analyze --llm auto
# or: --llm hf-qwen | openai | anthropic | heuristic

$env:CODEEVOLVE_LLM_API_KEY = "..."          # OpenAI-compatible
$env:OPENAI_API_KEY = "..."
$env:ANTHROPIC_API_KEY = "..."
$env:CODEEVOLVE_HF_MODEL = "Qwen/Qwen2.5-0.5B-Instruct"
$env:CODEEVOLVE_SKIP_HF = "1"                # force no local download

hardware / --llm auto picks local Qwen vs cloud vs heuristic from RAM/VRAM/disk (iQueue-style ladder).
