# Build Token Value > Tarski-honest metamethodology for estimating AI build tokens and three value layers > (L1 cash / L2 API-list / L3 human). Multi-op fan-out across Claude Code, Codex, Grok Build. > Product: Pharosiraptor. ## Site - Dashboard: / - Certificate seed: /data/estimate.json - Methodology: /data/methodology.json · /methodology/SKILL.md - Agents: /data/agents.json - Prompts: /prompts/00-multi-op-compose.md … /prompts/10-gemini-cli.md - Scripts: /scripts/*.py - Bare git (dumb-HTTP): /git/build-token-value.git ## Clone ```bash git clone https://build-token-value.pages.dev/git/build-token-value.git ``` ## Quick run ```bash python scripts/collect_evidence.py --since 2025-11-01 --out evidence.json python scripts/estimate_value.py --evidence evidence.json --out data/estimate.json ``` ## Deep links - Multi-op prompt: /#prompt/multi-op - Per agent: /#prompt/claude-code · codex · grok-build · cursor · copilot · windsurf · aider · cline · devin · gemini-cli ## Invariants 1. Multi-op fan-out when ≥2 backends ready (OTC multiset — not exclusive cascade). 2. Claude stats-cache is primary measured source. 3. Grok/Codex session bytes are semi-decidable proxies. 4. Never collapse L1 / L2 / L3 / L4 market value. 5. Name Tarski residuals explicitly. 6. Public estimate.json is sanitized (no local filesystem paths).
