cursor-asdd

Repository rules for ASDD, or Agentic Spec-Driven Development, a way of managing code changes around written requirements and separate checks. They define how agents, pull requests, specifications, tests, and human approval work together.

In plain words
What is it for?
Use them when contributing to this repository to find the required instructions, connect features or fixes to a specification, disclose agent use, sign commits, choose the correct lane, and leave merging to a human.
Why use it?
They make responsibilities and merge conditions explicit, including agent disclosure, signed commits, one workflow label, a specification for most changes, and independent testing.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

cursor-asdd 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 2d 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.

What it actually says

This repository is governed by ASDD (Agentic Spec-Driven Development). Read AGENTS.md, the contribution constitution, before writing code here. These points are a pointer to it, not a second set of rules.

  • Disclose the agent in the pull request and the commit trailer, and sign every commit off (git commit -s).
  • Exactly one lane label per pull request; the set is in .asdd.yml.
  • A feature or fix points to a spec that defines "done"; only the chore lane is spec-exempt.
  • You are the developer. The test agents run on a different model, so your own tests are not the deciding check.
  • A human merges. Agents review and recommend; you do not merge your own work.

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.
