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 | $0.00078 | $0.01437 |
| Opus 5 | $0.00039 | $0.00718 |
| Sonnet 5 | $0.00016 | $0.00287 |
| Haiku 4.5 | $0.00008 | $0.00144 |
Grade A, and why
agent-creator 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 10d 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 — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Creator
Создавайте агентские пакеты как переносимые системы, а не как промпты, которые работают только в текущем чате.
Core rule
Модель предлагает. Runtime, tools, tests, permissions, artifacts и reviewers доказывают.
Не доверяйте safety, tool execution, validation, memory hygiene и final acceptance только инструкции в промпте.
Перед началом
- Прочитайте
../grill-me/SKILL.md. - Зафиксируйте objective, target users, maturity, scope, autonomy, risk, allowed/forbidden actions, data sources, target platforms, export shape, validation и done condition.
- Прочитайте
../workflow-loop-me/SKILL.mdи соберите workflow notes, candidate loops и выбранный workflow spec. - Если пользователь дал ссылки на репозитории или инструменты, прочитайте
../repo-tool-librarian/SKILL.mdи сохраните их как catalog candidates без интеграции. - Для production/library/governed пакетов прочитайте
references/production-skill-os.md.
Обязательная форма серьезного agent package
- router / instruction entrypoint;
- Agent/Skill IR;
- versioned system identity and harness boundary for session, harness, sandbox, artifact store and credential broker;
- default-deny permission policy with approval binding, provenance-aware data flow and runtime enforcement;
- append-only run-event contract for effects, permissions, transfers, state revisions and budgets;
- workflow discovery notes, workflow spec и discovery ledger;
- repo/tool library для идей и reusable building blocks, не для автоматической интеграции;
- platform adapters;
- birth contract, runtime profile, birth plan, environment readiness и project context templates;
- IDE/runtime adaptation policy;
- focused skills или workflows;
- typed tool registry;
- permission matrix;
- hook registry, lifecycle event mappings и hook validation для правил, требующих автоматического enforcement;
- subagent topology decision, role registry, delegation plan, task/result contracts, run ledger, isolation, lifecycle и Subagent Eval Lab;
- memory and state model;
- workspace hygiene rules;
- checker/reviewer layer;
- context packaging policy;
- Trigger Lab;
- eval-validity report with task inventory, feasibility witnesses, grader mapping, contamination checks and frozen holdout;
- Output Eval Lab with outcome, trajectory, boundary and stability graders, repeated trials and infrastructure calibration;
- Harness Assumption Registry and matched-budget Ablation Lab;
- workflow/negative fixtures;
- skill training lab and skill-candidate lifecycle;
- target conformance matrix;
- final evidence contract;
- release review;
- machine-readable release decision that reconciles required gates and derives allowed claims;
- evidence ledger and claim guard;
- package verification;
- install simulation from final zip;
- post-birth cleanup;
- runtime/devkit boundary.
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.

agent-creator is a skill published in the GitHub repository mekotenkov-ux/seomeatagentscreator (5 stars, last pushed 1mo ago), licensed MIT. It adds 78 tokens to every session and 1,437 once invoked, about $0.0004 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 2026-08-31.
