giltiq-mcp: Instructions file for Codex

AGENTS.md

giltiq-mcp AGENTS.md is an instructions file for Codex, OpenCode from giltiq/giltiq-mcp. It costs 424 tokens per session, scanned A, original, MIT.

A set of repository instructions for Giltiq's client-side MCP server, which connects coding agents to a VAT validation service over HTTPS. MCP is a standard way for an AI host to call external tools.

In plain words
What is it for?
Use it when developing, building, testing, or committing changes to the Giltiq VAT validation integration.
Why use it?
It records the project's architecture, tests, formatting rules, commit format, and shared project memory so changes follow the repository's conventions.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is giltiq/giltiq-mcp's own configuration. It tells Codex and OpenCode how to work on giltiq-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 giltiq-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

giltiq-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 today.

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.

What it actually says

giltiq-mcp — Agent Rules

Client-side MCP server for the Giltiq VAT validation API, published as @giltiq/mcp on npm. Stdio transport only: an MCP host (Claude Desktop, Cursor, Claude Code) launches it as a subprocess on the user's machine and it calls api.giltiq.de over HTTPS like any REST client. No server-side infrastructure.

  • Exposes the same tool set as the hosted giltiq-mcp-server (mcp.giltiq.de): validate, status, usage, register, plus qualified-confirmation and receipt retrieval. The two repos are kept in lockstep; neither supersedes the other (DECISIONS.md, DECISION-007 in the workspace root).
  • TypeScript ESM, Biome (tabs), Vitest (npm test). Quality gates before commit: npx biome check ., npm run build, npm test.
  • Agent commits: agent: <type>(<scope>): <description>.
  • Workspace-wide rules (protected paths, production SSH freeze, API-parity pre-flight) live in ../CLAUDE.md and ../giltiq-agent/CLAUDE.md.

Project memory (Hindsight)

This repo is scoped to the shared giltiq Hindsight bank (see .pi/hindsight.json), which holds both engineering context and company strategy (business plan, DECISIONS.md, hypotheses, gate state). Before scouting the codebase or re-deriving architecture, check the hindsight_knowledge tool (action "search" or "tree", then "get") for existing pages — component map, core concepts, conventions, key decisions, initiatives. They refresh automatically from project memory. Use hindsight_recall for dated facts (what was decided when, what shipped vs. what a card claims). When you learn something durable — a decision, a root cause, an incident, a market signal — retain it with hindsight_retain and name the source.

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.
