GODKILLER MCP

Phase kernel for Google Antigravity.
Plan. Gate. Prove on disk. Then claim done — or get blocked.

pip install godkiller-mcp

Mission

Antigravity skips phases. GODKILLER does not allow that.

goal → mode → evidence/plan → gated edit → disk verify → claim_done

Arena — Antigravity A/B (the real proof)

Pre-solved twins that both pass 516 prove nothing. The honest protocol:

1. Reset arms to sealed buggy 1_ORIGINAL

2. You open Antigravity on 3_WITHOUT_MCP with MCP off → agent tries → we score

3. Reset / open 2_WITH_MCP with MCP on → agent tries → we score

4. Compare 11 dimensions (fail-closed on missing evidence)

11 dimensions

$env:GODKILLER_ARENA_ROOT="C:\Users\ASUS\Desktop\GODKILLER_ISOLATED_ARENA"
python -m benchmarks.reset_arena
# → open Antigravity bare, then:
python -m benchmarks.score_11 --arm 3_WITHOUT_MCP
# → open Antigravity + MCP, then:
python -m benchmarks.score_11 --arm 2_WITH_MCP
python -m benchmarks.score_11 --compare

Scorecard lands in GODKILLER_ISOLATED_ARENA\logs\11_dimension_scorecard.md after your runs — not a fake pre-fill.

Engine gauntlet (in-package kernel proof)

python -m benchmarks.run_arena --mode engine
pytest -q

Kernel

goal → mode → evidence/plan → gated edit → disk verify → hollow → claim_done

/ultradeep

queue → think (≥3 hypotheses) → plan → edit_safe (1 path) → verify → advance

Council

Host mode (default): MCP ส่งบท Coder / Hacker / Optimizer ให้โมเดลใน IDE → council_submit → council_finalize

API mode (optional): GODKILLER_LLM_API_KEY / OPENAI_API_KEY + mode=api

Install

pip install godkiller-mcp
# pip install 'godkiller-mcp[browser]' && playwright install chromium
# pip install 'godkiller-mcp[scrape]'
# optional OCR: pip install pytesseract  (+ Tesseract binary)

Alternate: python -m godkiller_mcp.server

Tools — Kernel vs recovery vs experimental

Kernel (the product): gk_route · gk_mode · gk_task · gk_phase · gk_evidence · gk_verify (bundle / hollow / probe / ledger) · gk_memory · gk_code (map / search / read_full / council*) · gk_meta (plan)

Recovery: gk_code.self_heal · gk_code.pipeline

Optional / experimental: gk_browser · gk_scan · gk_handoff · scrape · skillify · confidence · auto_fix · soak / competitor

Env: GODKILLER_PLAN_LOCK=1 (default) · GODKILLER_FAULT_PROBE=1 (default) · GODKILLER_STRICT=1 (opt-in) · GODKILLER_DEV_RELAX=1 (local soft bypass only)

Modes

Security

• Secret values never returned over MCP (names only)

• Prefer shell=False verify/soak · verify command allowlist

• Forge-proof evidence types: PASSING_TEST / BLAST_RADIUS / EDIT_SAFE

• Network scrape/browser are explicit invocations

State lives under GODKILLER_HOME or <cwd>/.godkiller/.
