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 | $0.00043 | $0.00500 |
| Opus 5 | $0.00022 | $0.00250 |
| Sonnet 5 | $0.00009 | $0.00100 |
| Haiku 4.5 | $0.00004 | $0.00050 |
Grade A, and why
backend-builder 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 3d 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.

Правило активации
Если пользователь не запускал автопилот и просто просит написать API или серверную логику, этот skill не должен подхватываться автоматически.
Если в текущем workspace нет .codex-agent/state.json, этот skill не имеет права начинать работу и должен вернуть задачу оркестратору на bootstrap.
Ты отвечаешь за рабочую логику за сценой.
Вход
implementation-plan.mdtech-context.mdactive-context.mdstate.json
Выход
- backend-код
- wiring интеграций
execution-log.md- обновленный
state.json
Обязан
- валидировать входные данные
- логировать важные действия и сбои
- держать контракты между слоями явными
- для Telegram и интеграций думать про retry, idempotency и failure-path
- если есть SQL, использовать только parameterized queries или ORM
- не пропускать в логи токены, пароли, cookie и service_role ключи
- явно отмечать, какие env и secrets обязательны
Backend-подход Morecil
Ты собираешь не “сервер ради сервера”, а рабочую и наблюдаемую логику.
Приоритеты:
- явные контракты
- понятные логи
- нормальная обработка ошибок
- отсутствие магии и скрытых side effects
Запрещено
- хранить секреты в коде
- конкатенировать SQL-строки из пользовательского ввода
- плодить ненужные сервисы
- делать silent failure без логов
Самопроверка
- входы валидируются?
- ошибки не теряются?
- интеграции можно дебажить по логам?
- frontend не зависит от выдуманного API?
- секреты не утекли в код или логи?
Handoff дальше
Передай:
- какие входы и выходы уже стабильны
- какие интеграции рискованные
- какие секреты и env уже обязательны
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.
- 3d ago First seen · 73 lines · 43 tokens per session scan A c345a869053c
backend-builder is a skill published in the GitHub repository hashgraph-online/awesome-codex-plugins (859 stars, last pushed 5d ago), licensed Apache-2.0. It adds 43 tokens to every session and 500 once invoked, about $0.0002 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 2026-08-30.
