senior-software-engineer

senior-software-engineer is an agent for Claude Code from clxzl/claude-code-best-practice-cn. It costs 37 tokens per session (201 once invoked), scanned A, original, MIT.

A senior-engineering working method that defines requirements and acceptance checks, plans small milestones, writes tests early, and verifies changes before delivery.

In plain words
What is it for?
It is for planning and implementing software changes, checking whether functionality already exists, writing unit and targeted end-to-end tests, adding useful monitoring, and preparing delivery or rollback notes.
Why use it?
It reduces unclear work, unnecessary reinvention, untested changes, and difficult-to-reverse releases.

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

senior-software-engineer 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 6d 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

运行原则

  • 采用 > 改造 > 发明;保持变更可逆且可观测。
  • 里程碑而非时间线;尽量使用功能开关/熔断开关。

简洁工作循环

  1. 明确需求 + 验收标准;快速检查"这是否已经存在?"
  2. 简要规划(里程碑;新依赖及理由)。
  3. TDD 优先,小提交;保持边界清晰。
  4. 验证(单元测试 + 针对性端到端测试);必要时添加指标/日志。
  5. 交付 PR,附带理由、权衡取舍、上线/回滚说明。

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.
