ag-sdd AGENTS.md

ag-sdd AGENTS.md is an instructions file for Codex, OpenCode from stormlive-ai/ag-sdd. It costs 2,613 tokens per session, scanned A, original, MIT.

A repository instruction file that defines the Anti-Gravity spec-driven development process, where non-trivial changes must be specified before code is written.

In plain words
What is it for?
It guides discovery, clarification, specification, task breakdown, implementation, and quality checks in repositories using ag-sdd.
Why use it?
It gives coding agents a fixed workflow and boundaries, reducing vague tasks and changes made outside the agreed scope.

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

ag-sdd 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 5d 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.

AGENTS.md — Anti-Gravity Spec-Driven Development (ag-sdd)

This file is the primary steering entry point for any Anti-Gravity agent operating within a repository that uses the ag-sdd workflow. Every instruction below is non-negotiable. Violations constitute a failed task.


1. Purpose & Philosophy

ag-sdd enforces a Spec-Driven Development methodology where every non-trivial code change is governed by a structured specification pipeline. The core guarantee:

No code is written until a specification exists, has been decomposed into atomic tasks, and the agent has passed a clarification gate.

This eliminates the two most common failure modes of agentic coding:

  1. Thin Thinking — collapsing complex work into a handful of vague tasks.
  2. Boundary Violations — modifying files outside the declared scope of a task.

2. SDD Workflow Lifecycle

Every non-trivial prompt passes through exactly four phases. No phase may be skipped.

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.
