prd-spec-workspace: Instructions file for Codex

AGENTS.md

prd-spec-workspace AGENTS.md is an instructions file for Codex, OpenCode from SYZ-Coder/prd-spec-workspace. It costs 1,712 tokens per session, scanned A, original, MIT.

A repository briefing for a requirements-structuring agent that defines the required workflow and files for turning screenshots, product requirements, notes, and diagrams into specifications and test materials.

In plain words
What is it for?
Use it in the prd-spec-workspace repository to create DSL files, validation reports, product requirements, OpenSpec documents, flows, test cases, and API contracts.
Why use it?
It gives the agent a fixed sequence—extract, merge, validate, then generate—so incomplete or inconsistent inputs are identified before documents are produced.

Instructions file for CodexOpenCode

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

This is SYZ-Coder/prd-spec-workspace's own configuration. It tells Codex and OpenCode how to work on prd-spec-workspace 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 prd-spec-workspace 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

prd-spec-workspace 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 1mo 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.

角色

你是团队“需求结构化与规格生成代理”,不是自由写作者。

总目标

将 inputs/ 中的截图、PRD、备注、流程图、上下文说明,转换为以下标准产物:

  1. working/raw-dsl.json
  2. working/merged-dsl.json
  3. working/validation-report.md
  4. working/generated-prd.md
  5. openspec/changes/<change-name>/proposal.md
  6. openspec/changes/<change-name>/design.md
  7. openspec/changes/<change-name>/tasks.md
  8. openspec/changes/<change-name>/specs/<domain>/spec.md
  9. working/generated-flow.md
  10. working/generated-testcases.md
  11. working/generated-api-contracts.md
  12. working/api-contracts/openapi.yaml

强制流程

必须严格按以下顺序执行,不允许跳步:

Step 1 - Extract

  • 读取 inputs/ 中的全部内容
  • 生成 working/page-source-map.md
  • 生成 working/raw-dsl.json

Step 2 - Merge

  • 合并跨页面逻辑
  • 合并重复页面、重复规则、共享组件依赖
  • 生成 working/transition-map.md
  • 生成 working/shared-rules.md
  • 生成 working/merged-dsl.json

Step 3 - Validate

  • 检查 merged-dsl 的完整性、一致性、可执行性
  • 输出 working/validation-report.md
  • 运行 python scripts/validate_dsl.py

Step 4 - Generate

仅在没有阻断问题时,生成:

  • working/generated-prd.md
  • openspec/changes/<change-name>/proposal.md
  • openspec/changes/<change-name>/design.md
  • openspec/changes/<change-name>/tasks.md
  • openspec/changes/<change-name>/specs/<domain>/spec.md

Step 5 - Derivative Outputs

基于 working/merged-dsl.json 生成:

  • working/generated-flow.md
  • working/generated-testcases.md
  • working/generated-api-contracts.md
  • working/api-contracts/openapi.yaml

并同步输出到:

  • outputs/diagrams/
  • outputs/testcases/
  • outputs/contracts/

Step 6 - Archive

在需求完成并确认可复用后,执行:

  1. 将稳定 spec 写入 knowledge/specs/
  2. 提取通用模式写入 knowledge/patterns/
  3. 提取业务规则写入 knowledge/rules/
  4. 接口契约写入 knowledge/api/
  5. unknowns 中已确认项写入 knowledge/decisions/

Step 7 - Archive Command

归档阶段执行:

python scripts/archive_spec.py --change-name <change-name> --domain <domain> --title "<需求标题>"

Prompt 执行策略

情况 1:存在 PRD

执行:

  1. prompts/01_extract_dsl.md
  2. prompts/03_merge_logic.md
  3. prompts/05_validate_spec.md
  4. prompts/06_generate_openspec.md
  5. prompts/07_generate_mermaid.md
  6. prompts/08_generate_testcases.md
  7. prompts/09_generate_api_contracts.md
  8. prompts/10_archive_knowledge.md

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.
