Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is romaco-labs/romaco-mcp's own configuration. It tells Codex and OpenCode how to work on romaco-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything romaco-mcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

romaco-mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Purpose

This repository publishes @romaco/mcp, an open-source MCP server for deterministic market analysis and optional romaco-charts control.

Read first

Product boundaries

  • MCP is local/headless first. Browser chart bridge and remote gateway are optional adapters.
  • romaco-charts owns chart execution and host-enforced write policy.
  • romaco.io owns demo, docs, and conversion.
  • SaaS is paused and must not become a core dependency.
  • Do not copy ROA-I, WASM, institutional-data, billing, auth, pricing, or other proprietary/SaaS internals into this public repository.
  • Public analysis uses approved public contracts such as MarketSummary.
  • Promise: computed by code, interpreted by AI, optionally drawn on chart. Never claim zero hallucination risk.

Architecture invariants

  1. compression/** stays pure and imports only itself.
  2. Domain imports domain/compression only.
  3. Application imports application/domain/compression only.
  4. Inbound adapters call use cases; they never import outbound adapters.
  5. Outbound adapters implement application ports; they never import inbound adapters.
  6. Tool handlers do not access repositories, gateway, chart bridge, market-data implementations, filesystem, or process state directly.
  7. External payloads are validated at adapter boundaries.
  8. Chart writes remain subject to host policy and explicit identity checks.
  9. Legacy root modules and src/tools/** are temporary shims. Do not add new business logic there.
  10. MCP approval tokens never bypass host actionPolicy. Do not claim process-local idempotency is crash-safe or exactly-once.

test/architecture/dependency_rules.test.ts enforces dependency direction. Update architecture docs and that test together when a boundary changes.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
