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 | $0.00138 | $0.02423 |
| Opus 5 | $0.00069 | $0.01211 |
| Sonnet 5 | $0.00028 | $0.00485 |
| Haiku 4.5 | $0.00014 | $0.00242 |
Grade A, and why
pagination 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.

Pagination Skill — 分页设计
何时使用
- 设计 list API(任何返回多条记录的端点)
- 排查"翻到第 1000 页超慢" / "数据漏 / 重复"
- 需要无限滚动 UI(feed / timeline)
- Elasticsearch / Mongo 深分页性能问题
- GraphQL connection 规范实现
一、两大流派
Offset/Limit(最熟悉,但坑最多)
GET /users?offset=0&limit=20
GET /users?page=1&page_size=20
优点:直观 / 跳页方便("第 5 页")/ 显示总数 缺点:
- 深分页慢:
OFFSET 100000数据库要扫描丢弃 10 万行 - 数据漂移:翻页期间有新数据插入 → 重复或漏数据
- 不稳定排序:相同排序值的多行顺序不定 → 翻页错乱
Cursor(推荐用于 feed / 大数据集)
GET /users?cursor=eyJpZCI6MTIzNDV9&limit=20
优点:性能稳定(O(1) 不论第几页)/ 无漂移问题 缺点:不支持跳页 / 不显示总数 / 实现稍复杂
二、Cursor 实现模式
1. 简单单字段 cursor
-- 第一页
SELECT * FROM users ORDER BY id LIMIT 20
-- 后续页:用最后一条 ID 当 cursor
SELECT * FROM users WHERE id > $cursor ORDER BY id LIMIT 20
cursor = 最后一条的 id(base64 编码后给客户端)。
2. 复合键 cursor(按时间倒序)
SELECT * FROM posts
WHERE (created_at, id) < ($cursor_ts, $cursor_id)
ORDER BY created_at DESC, id DESC
LIMIT 20
为什么加 id 做 tie-breaker:相同 created_at 的多条不加 id 会乱序 / 翻页漏。
3. cursor 编码
// 服务端
function encodeCursor(row) {
return Buffer.from(JSON.stringify({
ts: row.created_at.toISOString(),
id: row.id,
})).toString('base64url')
}
function decodeCursor(s) {
return JSON.parse(Buffer.from(s, 'base64url').toString('utf8'))
}
安全:不要让客户端伪造 cursor 跳过权限。可以 HMAC 签名 / 加盐:
const cursor = base64({ ts, id, sig: hmac(ts + id, secret) })
或者只暴露不可猜的 ID(UUID v7)— 让 cursor 自然失效。
4. 双向分页
GET /posts?after=cursor1&limit=20 # 下一页
GET /posts?before=cursor1&limit=20 # 上一页
-- after
WHERE (ts, id) < ($after.ts, $after.id) ORDER BY ts DESC, id DESC
-- before(注意结果集要再反转)
WHERE (ts, id) > ($before.ts, $before.id) ORDER BY ts ASC, id ASC
-- 然后 reverse() 给客户端
三、Keyset Pagination(SQL 索引利用)
-- ❌ OFFSET 慢
SELECT * FROM users ORDER BY created_at DESC OFFSET 100000 LIMIT 20;
-- 扫 100020 行丢弃 100000
-- ✅ Keyset(cursor 模式)
SELECT * FROM users
WHERE (created_at, id) < ('2024-01-01', 12345)
ORDER BY created_at DESC, id DESC
LIMIT 20;
-- 利用 (created_at, id) 索引直接 seek 到位置,扫 20 行
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.

pagination is a skill published in the GitHub repository cass-2003/local-workflow-skill (12 stars, last pushed 2mo ago), licensed MIT. It adds 138 tokens to every session and 2,423 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
