CSSwitch: Skill for Claude Code

.agents/skills/csswitch-change-checks/SKILL.md

csswitch-change-checks is a skill for Claude Code, Codex from SuperJJ007/CSSwitch. It costs 30 tokens per session (246 once invoked), scanned A, original, MIT.

A guide for choosing limited checks after changing CSSwitch source code, tests, or Markdown files. It distinguishes quick in-progress checks from checks for a committed change range.

In plain words
What is it for?
Use it to select and report tests or other checks, identify changed file layers, state what was not run, and assess CSSwitch changes against their owning checks.
Why use it?
It helps report the relevant risk and evidence without overstating a focused check as proof that all source code is correct.

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

csswitch-change-checks 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 2mo 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

CSSwitch change checks

Use this Skill to select and report checks after an implementation, test, or documentation change. Read 代码作者规则, 开发, and 自动测试 before selecting evidence.

  • In quick WIP mode, work from the requester’s declared goal and changed paths. Report the highest F0–F3 risk, scope, suggested owning checks, evidence layer, and items not run. Do not guess a base or read untracked-file contents.
  • In candidate or committed-range mode, require the requester to supply base and head. Report the resolved base, head, merge-base, and the committed, staged, unstaged, and untracked path layers; list untracked paths only.
  • Do not turn a static-mapping miss into a lower risk. A focused PASS is not SOURCE-GREEN; use the single source-closure gate only under the conditions in the linked operations.
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.
