x-dev

x-dev is a skill for Claude Code, Codex from KtKID/x-dev-pipeline. It costs 57 tokens per session (624 once invoked), scanned A, original, MIT.

A development workflow for completing tasks from a task folder. It follows the task's README and checklist, implements work in dependency order, and records verification evidence.

In plain words
What is it for?
Use it to implement task batches, run automated checks, document manual checks, route failures for fixing, and report what was completed or remains blocked.
Why use it?
It turns a task's requirements, tests, risk level, and completion status into one repeatable process.

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

x-dev 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.

What it actually says

x-dev — 统一执行

输入与边界

目标目录必须有 README.mddev-checklist.md。README 的 risk:、验收 Scenario 与技术设计定义实现边界;dev-checklist 定义顺序与状态;dev-report 记录改动及 verify 证据。x-dev 消费 task,不创建需求包。

执行

  1. 阅读 README 的核心目标、涉及模块、架构拆分策略、技术设计、验收与自动化测试责任;模块段含 spec 引用时跟读对应模块文档。
  2. 运行 python3 tools/xdev.py status <task-dir> --jsongraph <task-dir> --json。同优先级、无依赖、无同文件写冲突的 ready task 可并行;有依赖的 task 按拓扑序推进。
  3. 将当前 checklist 项更新为进行中,实现时保持 README 定义的公开契约、失败路径与范围。
  4. 每个 验证: auto Scenario 在 dev-report.md 写一个 auto fenced verify 块,用 scenario: 精确回指;补齐单元、契约和边界测试。manual Scenario 写步骤块。
  5. 实现完成后更新 checklist 为待测试,运行全部 verify 块声明的命令;通过后更新为测试通过。
  6. 运行 python3 tools/xdev.py verify <task-dir> --json:exit 2 修正 dev-report 格式;exit 1 将 fail 与 uncovered 一次交给 x-fix;exit 0 继续 risk 路由。
  7. Q0/Q1 输出完成回执及定级依据;Q2 调 x-qa-gate RC;Q3 调 x-qa-gate R1→R2→R3。Gate ② 全部通过后把 checklist 标为 [x] ✅

状态与记录

状态顺序为 [ ] ⏳ → [ ] ▶️ → [ ] 🟡 → [x] 🟢 → [x] ✅;Gate ② 负责最终 ✅。reports/ 位于 task 根目录下,verify 或 qa-gate fail 依既有共享 fix-counter 交给 x-fix 批量修复。

完成回执

报告当前 task、完成项、修改文件、verify 结果、risk 路由、Gate ② 结果、manual 待验收项和遗留阻塞。连续模式在一个 task Gate 完成后按 graph 读取下一批 ready 项。

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

x-dev is a skill published in the GitHub repository KtKID/x-dev-pipeline (12 stars, last pushed 1mo ago), licensed MIT. It adds 57 tokens to every session and 624 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Use in the Review phase before claiming any Java/Spring task is complete, fixed, or passing. Spawns the auditor subagents that check the implementation against every applicable skill, rule, and memory item, runs the test suite for fresh evidence, and re-spawns for at most two fix rounds before reporting what survives.…
