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 | $0.00063 | $0.01780 |
| Opus 5.5 | $0.00025 | $0.00712 |
| Sonnet 5.5 | $0.00013 | $0.00356 |
| Haiku 4.5 | $0.00006 | $0.00178 |
Grade A, and why
skill-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 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.
This is a copy
92% identical to skill-creator — 403 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

About Skills
A Skill is a self-contained folder that gives the agent specialized knowledge, a workflow, or tools for one kind of task. Think of it as an onboarding guide: it turns a general-purpose agent into one equipped with procedural knowledge no model has on its own.
Skills provide:
- Workflows: multi-step procedures for a specific domain
- Tool integrations: how to work with specific file formats or APIs
- Domain expertise: schemas, conventions, business rules
- Bundled resources: scripts, references, and assets for repetitive work
Where Skills live
| Scope | Folder | Notes |
|---|---|---|
| Personal | ~/.emperor/skills/<name>/ |
Available in every session |
| Project | <project>/.emperor/skills/<name>/ |
Build sessions of that project only; overrides a personal Skill with the same name |
| Built-in / Plugin | shipped with Emperor or a Plugin | Read-only |
Create, update, delete, and import Skills only with skill_manage. These folders are outside the writable workspace, so file and shell tools cannot write them; skill_manage asks the user for approval unless the session runs with full access. To change a built-in or Plugin Skill, create a personal Skill with the same name; it takes precedence.

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.

skill-creator is a skill published in the GitHub repository TheSyart/emperor-agent (206 stars, last pushed yesterday), licensed MIT.
