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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00097 | $0.02092 |
| Opus 5 | $0.00048 | $0.01046 |
| Sonnet 5 | $0.00019 | $0.00418 |
| Haiku 4.5 | $0.00010 | $0.00209 |
Grade D, and why
shell-scripting-2 scanned grade D with 2 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 8d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Shell脚本开发技能 (Shell Scripting Skill)
快速规则(日常开发时自动加载,只需读到这里)
[Shell核心清单] ① 脚本首行
#!/usr/bin/env bash+set -euo pipefail② 变量必须"$var"双引号包裹防止分词 ③ 路径用"$(cd "$(dirname "$0")" && pwd)"获取脚本所在目录 [安全三禁] ❌eval "$user_input"❌无引号变量展开 ❌rm -rf /或rm -rf $VAR/(VAR可能为空) [健壮性铁律] 命令失败必须有处理(set -e或显式检查$?),临时文件用mktemp+trap清理
写/改Shell脚本时,强制遵守:
- Shebang+严格模式:
#!/usr/bin/env bash+set -euo pipefail(-e:命令失败即退出 -u:未定义变量报错 -o pipefail:管道中任一命令失败即失败) - 引号规则:变量展开必须双引号
"$var",防止空格/通配符导致分词。路径变量尤其重要 - 错误处理:关键命令后检查返回值,或用
|| { echo "失败"; exit 1; } - 临时文件:
mktemp创建 +trap 'rm -f "$tmpfile"' EXIT清理,禁止硬编码/tmp/xxx - 日志输出:用函数统一日志格式
log() { echo "[$(date '+%H:%M:%S')] $*"; },错误输出到stderr - 可移植性:优先POSIX兼容语法,用
command -v检查依赖是否存在 - 幂等设计:脚本重复执行不应产生副作用(mkdir -p / cp而非追加写入)
脚本模板
标准脚本骨架
#!/usr/bin/env bash
set -euo pipefail
# 脚本所在目录(解析符号链接)
SCRIPT_DIR="$(cd "$(dirname "$0")" && pwd)"
# 日志函数
log() { echo "[$(date '+%H:%M:%S')] $*"; }
err() { echo "[$(date '+%H:%M:%S')] ERROR: $*" >&2; }
die() { err "$@"; exit 1; }
# 依赖检查
for cmd in go rsync ssh; do
command -v "$cmd" >/dev/null 2>&1 || die "缺少依赖: $cmd"
done
# 清理函数
cleanup() {
# 清理临时文件等
:
}
trap cleanup EXIT
# 主逻辑
main() {
log "开始执行..."
# ...
log "完成"
}
main "$@"
部署脚本模板
#!/usr/bin/env bash
set -euo pipefail
SCRIPT_DIR="$(cd "$(dirname "$0")" && pwd)"
REMOTE_HOST="user@server"
REMOTE_DIR="/path/to/deploy"
SERVICE_NAME="myservice"
log() { echo "[$(date '+%H:%M:%S')] $*"; }
die() { echo "[$(date '+%H:%M:%S')] ERROR: $*" >&2; exit 1; }
# 构建
log "构建中..."
cd "$SCRIPT_DIR"
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o "build/${SERVICE_NAME}" . || die "构建失败"
# 上传
log "上传到 $REMOTE_HOST..."
rsync -az "build/${SERVICE_NAME}" "$REMOTE_HOST:$REMOTE_DIR/" || die "上传失败"
# 重启
log "重启服务..."
ssh "$REMOTE_HOST" "sudo systemctl restart $SERVICE_NAME" || die "重启失败"
# 验证
log "等待服务启动..."
sleep 2
ssh "$REMOTE_HOST" "systemctl is-active $SERVICE_NAME" || die "服务未正常启动"
log "部署完成 ✓"
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.

shell-scripting-2 is a skill published in the GitHub repository cass-2003/local-workflow-skill (12 stars, last pushed 2mo ago), licensed MIT. It adds 97 tokens to every session and 2,092 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
