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 | $0.00083 | $0.00958 |
| Opus 5.5 | $0.00033 | $0.00383 |
| Sonnet 5.5 | $0.00017 | $0.00192 |
| Haiku 4.5 | $0.00008 | $0.00096 |
Grade A, and why
prompt-library 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Prompt Library — паттерны формулировки задач
Локальный снапшот официальной библиотеки промптов Claude Code (52 промпта, 5 фаз SDLC, 15 категорий). Полный каталог — в prompts.md.
Принцип использования: постоянно. Получил задачу → определи фазу/категорию → проверь, применён ли паттерн соответствующего промпта. владелец спрашивает «как попросить» или даёт расплывчатый запрос → подбери конкретный промпт из каталога.
6 паттернов, почему эти промпты работают
- Outcome, не шаги. Скажи, что нужно получить, — файлы Claude найдёт сам.
add rate limiting to the public API and make sure existing tests still pass - Дай способ самопроверки. run / test / compare / verify в том же промпте —
Claude итерирует, а не останавливается после первой попытки.
write the migration, run it against the dev database, and confirm the schema matches - Укажи референс. Существующий файл/тест/паттерн → новый код консистентен.
add a settings page that follows the same layout as the profile page - Измеримая цель. Метрика + порог = однозначное «готово».
get the bundle size under 200KB and show me what you removed - Дай артефакт. Ошибки, логи, скриншоты, plan-output — вставляй сырьё или
@файл, а не пересказ.why is the build failing? @build.log - Скажи формат ответа. Формат, длина, аудитория — под то, как ответ будет использован.
Карта фаз → категории
| Фаза | Категории |
|---|---|
| Discover | Onboard, Understand |
| Design | Plan, Prototype |
| Build | Implement, Test, Refactor, Review, Steer |
| Ship | Git, Release |
| Operate | Debug, Incident, Data, Automate |
Алиасы симптомов → категория (не очевидно из названий):
- тормозит / медленно / slow / performance / latency / оптимизировать → Build·Refactor (Optimize against a measurable target)
- миграция / переезд на новый API / переписать на другой язык → Build·Refactor
- прод упал / 500 / инцидент / логи → Operate·Incident; падает тест или билд → Operate·Debug
- «надоело повторять» / рутина → Operate·Automate (скилл, хук, MCP)
- baseline для measurable-цели неизвестен → сначала замерь или спроси порог (паттерн 4)
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

prompt-library is a skill published in the GitHub repository KirillSachkov/sachkov-stack (4 stars, last pushed 2mo ago), licensed MIT. It adds 83 tokens to every session and 958 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-31.
