x-verify

x-verify is a skill for Claude Code from KtKID/x-dev-pipeline. It costs 55 tokens per session (366 once invoked), scanned A, original, MIT.

A fact-checking gate that reruns the automated checks listed for a development task and reports which checks passed, failed, or still need a person. It is one step in a larger development process.

In plain words
What is it for?
Use it after development or when you need to repeat task verification. Failed checks are written to a verification report and handed to the x-fix process.
Why use it?
It replaces assumptions about whether a change works with recorded command results and a complete list of failures.

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-verify 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 7d 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.

输入

README.md 的验收 Scenario 与 dev-report*.md fenced verify 块。引擎负责复跑命令、比较 exit/输出、列出 manual 和自动场景覆盖。

流程

  1. 运行 python3 tools/xdev.py verify <task-dir> --json
  2. exit 0:输出 pass N / manual M 回执,不写报告。
  3. exit 1:读取 fail 的 output_tail 与 uncovered,必要时用 --only <id> 复跑一个块;写 reports/verify/verify-report-<timestamp>.md,将完整 failure 清单交 x-fix。
  4. exit 2:指出 dev-report verify 格式或路径问题,退回 x-dev;不递增 fix-counter。

约束

  • 只报告命令与覆盖事实;代码质量由 x-qa-gate 处理。
  • fail 时跑完全部 auto 块后一次交付完整清单。
  • reports/.fix-counter、三轮上限和 x-fix 批量修复协议保持现有定义。

回执

🛡️ Gate① verify ✅ · pass N · manual M 待人工
🛡️ Gate① verify ❌ · fail N · uncovered M → x-fix

What ships with it

1 file 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.
