bar-assistant-mcp-server: Instructions file for Codex

AGENTS.md

bar-assistant-mcp-server AGENTS.md is an instructions file for Codex, OpenCode from zhdenny/bar-assistant-mcp-server. It costs 2,011 tokens per session, scanned A, original, MIT.

A project guide for Bar Assistant MCP Server, a Node.js and TypeScript server that connects applications to tools through MCP. It defines which documentation files govern development, architecture, data, visual standards, and interfaces.

In plain words
What is it for?
Use it when developing, reviewing, or documenting the Bar Assistant MCP Server. It covers project setup, versioning, documentation selection, coding guidance, architecture, data handling, and interface standards.
Why use it?
It tells agents where the authoritative rules live and which document to read when the task is unclear. This avoids duplicating technical guidance or changing the wrong source file.

Instructions file for CodexOpenCode

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

This is zhdenny/bar-assistant-mcp-server's own configuration. It tells Codex and OpenCode how to work on bar-assistant-mcp-server 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 bar-assistant-mcp-server 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

bar-assistant-mcp-server 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent — Bar Assistant MCP Server (v1.0.13) — 2026-06-20

Strict Rule: Read this file at every session start.

Project Setup

  • Project Name: Bar Assistant MCP Server
  • Version: 1.0.13 — use bump script only, never manually edit
  • Status: Active
  • Tech Stack: Node.js, TypeScript, Express, Axios, MCP SDK
  • Context Anchors: None

Documentation Priority

  • docs/ is the source of truth for behavior, architecture, and implementation rules.
  • AGENTS.md holds only: session-critical rules, quick-reference checklists, metadata.
  • Do not duplicate detailed explanations here — link to docs/ instead.
  • Scope unclear? Open docs/ARCH_documentation-governance.md first — task→load mapping is there.

Documentation Governance

  • Implementation Standards: docs/GUIDE_developer.md — how we write code, refactor, and test.
  • Architecture & Data: docs/ARCH_technical-specs.md — data models, routing, system boundaries.
  • Visual & IO Standards: docs/STANDARDS_*.md — design tokens, output formats, interface specs.
  • Rule: Never consolidate these files without explicit intent. Keep concerns isolated to prevent accidental regressions.

AI Technical Governance (CRITICAL)

  • Discussion Precedence (CRITICAL): Strictly forbidden to create, modify, or delete any code/files until the plan is fully discussed and finalized with the user.

TDD Decision Rule

  • Use TDD for: logic, data processing, routing, rendering output, business rules.
  • Skip TDD for: docs, copy, rename, formatting, cosmetic edits.

Goal-Driven Execution

Verify → trace → build → confirm. Never guess → build → fix → repeat. Before multi-step tasks, state a brief plan: [Step] → verify: [check].

Response Style (CRITICAL)

  • Answer only what's asked. No intro, recap, outro, filler, or padding.
  • Markdown only when it helps (tables, code blocks).
  • Unsure → ask one question. No assumptions.

Writing Rules

Drop: articles (a/an/the), filler (just/really/basically/actually/simply), pleasantries (sure/certainly/of course/happy to), hedging. Fragments OK. Short synonyms (big not extensive, fix not "implement a solution for"). Technical terms exact. Code blocks unchanged. Errors quoted exact.

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.
