agents

agents is an instructions file for Codex, OpenCode from xy200303/spec-coding-mcp. It costs 819 tokens per session, scanned A, original, MIT.

A startup guide for collaborators working on a Spec Coding MCP project. It sets rules for focused changes, checking task context and validating work before marking it complete.

In plain words
What is it for?
Reading project tasks, following the required implementation order, recording progress, checking results and asking before making unclear high-risk changes.
Why use it?
It reduces accidental changes and makes the development process consistent, while using extra project tools only when they are available.

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

agents 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 3d 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.

Project: Spec Coding MCP

项目约定(所有人适用)

  • 改动小而聚焦,不做无关重构
  • 不要猜测业务规则,不确定时先确认
  • 不要覆盖他人已做的修改
  • 提交前验证

Spec Coding MCP(可选增强)

本项目支持 spec-coding-mcp 工具提供增强开发流程。

检测方法:查看可用工具列表中是否有 spec_context

◆ 如果你有 spec_context 工具

按以下硬性协议执行:

  1. 写任何代码前,先调用 spec_context 获取当前任务上下文。
  2. 只执行 spec/TODO 中列出的任务,不从对话历史推导。
  3. 按清单自上而下执行 → spec_checkpoint 记录进度 → 验证 → spec_done 归档。
  4. UI/UX 任务使用 ui-ux-pro-max skill。
  5. 需要原则指导时调用 spec_guidance_read

常见错误(不要做):不调 spec_context 就写代码 / 跳过验证直接 done / 监听型 TODO 自己标完成。

◆ 如果你没有 spec_context 工具

跳过本节。按项目常规开发流程工作:读需求 → 写代码 → 测试 → 提交。 不要尝试调用 spec_context、spec_checkpoint、spec_done 等不存在的工具。

Guidance 索引(仅 MCP 用户)

需要原则时调用 spec_guidance_read

Name 用途 何时读
engineering 工程规范、业务确认 实现/重构
ui-ux UI/UX skill 路由 前端/页面
spec-writing spec 工作流、验证器 创建/执行 spec
git-commit 安全提交流程 用户要求 commit
pr-submit PR 创建流程 用户要求 PR
quality-review 质量自检清单 done/commit/PR 前

Hard Stop(所有人适用)

Ask the user before implementing unclear or high-risk business rules involving money, permissions, state machines, concurrency, idempotency, retries, rollback, compliance, or role differences.

Boundaries(所有人适用)

  • Do not guess business rules.
  • Do not use stale conversation context over selected specs or open TODOs.
  • Do not overwrite user edits or make unrelated reshuffles.
  • Keep changes small, focused, and verified.

Shared Memory / Vault(仅 MCP 用户)

specs/ 目录作为持久化 Vault,在不同会话之间共享上下文:

specs/
├── README.md          # vault 索引与约定
├── active/            # 当前工作进行中
├── todo/              # 轻量执行清单
├── done/              # 已完成 spec + 最终行为契约
├── review/            # 源码审查任务
└── guidance/          # 可编辑 Agent 指导性提示词

无 MCP 工具时,specs/ 目录退化为普通项目文档目录。

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.
