ai-architect-mcp-spec: Instructions file for Codex

AGENTS.md

ai-architect-mcp-spec AGENTS.md is an instructions file for Codex, OpenCode from cdeust/ai-architect-mcp-spec. It costs 165 tokens per session, scanned A, original, MIT.

Project-specific instructions for an AI architecture and protocol repository. They tell the agent what documents to read, which design rules to preserve, and when behavior changes need contract or regression tests.

In plain words
What is it for?
They are for guiding code changes and reviews in that repository, especially around its protocol, dependency direction, TypeScript rules, and tests.
Why use it?
They provide local rules that general coding guidance may not know, reducing the risk of changes that violate the project's architecture or documented behavior. A contract test checks that an agreed interface still behaves as required.

Instructions file for CodexOpenCode

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

This is cdeust/ai-architect-mcp-spec's own configuration. It tells Codex and OpenCode how to work on ai-architect-mcp-spec 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 ai-architect-mcp-spec configures →

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

ai-architect-mcp-spec 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 yesterday.

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

ai-architect-mcp-spec

This project implements the stateless PRD pipeline reducer and its MCP host protocol. Read CLAUDE.md, docs/agent-guidance.md and CONTRIBUTING.md before changes or reviews.

Review guidelines

  • Preserve the host-driven contract: the server emits NextAction and the host executes it. Keep generation, submission and verification in their documented order.
  • Enforce the dependency direction in CONTRIBUTING.md: core is inward of validation/verification/strategy/meta-prompting, then orchestration, then mcp-server. Production TypeScript any requires the documented ADR.
  • Observable behavior changes must include contract or regression tests in the same PR, including error paths and emitted signals. Apply the project's source-discipline rules to constants and research claims.
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.
