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 | $0.00008 | $0.01451 |
| Opus 5 | $0.00004 | $0.00726 |
| Sonnet 5 | $0.00002 | $0.00290 |
| Haiku 4.5 | $0.00001 | $0.00145 |
Grade A, and why
disaster-recovery scanned grade A with 1 finding 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 12d 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.

灾难恢复
概述
灾难恢复计划、RTO/RPO、故障切换技能。
核心概念
RTO 与 RPO
RPO (Recovery Point Objective)
- 可接受的数据丢失量
- 决定备份频率
RTO (Recovery Time Objective)
- 可接受的恢复时间
- 决定恢复策略
示例:
- RPO = 1小时 → 每小时备份
- RTO = 4小时 → 需要热备或快速恢复
恢复策略
冷备 (Cold)
- 最低成本
- 最长 RTO
- 适合非关键系统
温备 (Warm)
- 中等成本
- 中等 RTO
- 定期同步数据
热备 (Hot)
- 最高成本
- 最短 RTO
- 实时同步
数据库恢复
MySQL 恢复
# 从备份恢复
mysql -u root -p < full_backup.sql
# 应用 binlog
mysqlbinlog mysql-bin.000001 | mysql -u root -p
# 时间点恢复
mysqlbinlog --stop-datetime="2024-01-15 10:00:00" mysql-bin.* | mysql -u root -p
# 主从切换
# 在从库执行
STOP SLAVE;
RESET SLAVE ALL;
# 应用程序切换连接
PostgreSQL 恢复
# 从备份恢复
pg_restore -d database backup.dump
# PITR 恢复
# recovery.conf
restore_command = 'cp /archive/%f %p'
recovery_target_time = '2024-01-15 10:00:00'
# 主从切换
pg_ctl promote -D /var/lib/postgresql/data
Redis 恢复
# 从 RDB 恢复
cp backup.rdb /var/lib/redis/dump.rdb
systemctl restart redis
# 从 AOF 恢复

文件系统恢复
# 从 tar 备份恢复
tar -xzvf /backup/system.tar.gz -C /
# 从 rsync 备份恢复
rsync -avz /backup/system/ /
# 恢复权限
restorecon -Rv /
引导修复
# 进入救援模式
# 挂载根分区
mount /dev/sda1 /mnt
mount --bind /dev /mnt/dev
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
chroot /mnt
# 修复 GRUB
grub-install /dev/sda
update-grub
故障切换
Keepalived 切换
# 检查状态
systemctl status keepalived
ip addr show | grep -w inet
# 手动切换
# 降低主节点优先级
# /etc/keepalived/keepalived.conf
vrrp_instance VI_1 {
priority 50 # 降低
}
systemctl reload keepalived
DNS 切换
# 修改 DNS 记录
# 降低 TTL(提前)
# 切换 A 记录指向备用 IP
# 验证
dig +short example.com
nslookup example.com
常见场景
场景 1:完整恢复流程

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.
- 12d ago First seen · 260 lines · 8 tokens per session scan A df6eed5ffd9f
disaster-recovery is a skill published in the GitHub repository chaterm/terminal-skills (59 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 8 tokens to every session and 1,451 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

c-files
Sync files to Google Drive, S3, Dropbox, OneDrive, and 70+ cloud providers using rclone.
skillci-guardrails
Use this skill whenever you create, edit, or review a Claude Skill — any SKILL.md file, or the eval cases/config next to one. Most SKILL.md files today are written or edited by an agent, not typed by hand, so this closes the loop by having the agent that just wrote the skill also author it defensively and verify it…
example-skill
Writes a single changelog entry summarizing a code change, given a short description of what changed.
clean-skill
A skill with no lint issues, used as a starting point for the lint-on-type test.
skill-with-referenced-issue
Has a clean SKILL.md but an unsafe referenced script.
council
Run one request through several skills in parallel, isolated subagents, then merge their answers or judge the single best one. Use when the user invokes /council (or /council manage), or uses clear multi-skill-comparison language like "try this with a few different skills", "compare how different skills answer this"…
