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 | $0.00060 | $0.00645 |
| Opus 5.5 | $0.00024 | $0.00258 |
| Sonnet 5.5 | $0.00012 | $0.00129 |
| Haiku 4.5 | $0.00006 | $0.00064 |
Grade A, and why
Createskill 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Createskill
MANDATORY skill creation framework for ALL skill creation requests.
Authoritative Source
Before creating ANY skill, READ: ${PAI_DIR}/skills/CORE/SkillSystem.md
Canonical example to follow: ${PAI_DIR}/skills/Blogging/SKILL.md
TitleCase Naming Convention
All naming must use TitleCase (PascalCase).
| Component | Format | Example |
|---|---|---|
| Skill directory | TitleCase | Blogging, Daemon, CreateSkill |
| Workflow files | TitleCase.md | Create.md, UpdateDaemonInfo.md |
| Reference docs | TitleCase.md | StyleGuide.md, ApiReference.md |
| Tool files | TitleCase.ts | ManageServer.ts |
| Help files | TitleCase.help.md | ManageServer.help.md |
Wrong (NEVER use):
createskill,create-skill,CREATE_SKILLcreate.md,update-info.md,SYNC_REPO.md
Workflow Routing
When executing a workflow, output this notification directly:
Running the **WorkflowName** workflow from the **Createskill** skill...
| Workflow | Trigger | File |
|---|---|---|
| CreateSkill | "create a new skill" | workflows/CreateSkill.md |
| ValidateSkill | "validate skill", "check skill" | workflows/ValidateSkill.md |
| UpdateSkill | "update skill", "add workflow" | workflows/UpdateSkill.md |
| CanonicalizeSkill | "canonicalize", "fix skill structure" | workflows/CanonicalizeSkill.md |
Examples
Example 1: Create a new skill from scratch
User: "Create a skill for managing my recipes"
→ Invokes CreateSkill workflow
→ Reads SkillSystem.md for structure requirements
→ Creates skill directory with TitleCase naming
→ Creates SKILL.md, workflows/, tools/
→ Generates USE WHEN triggers based on intent
Example 2: Fix an existing skill that's not routing properly
User: "The research skill isn't triggering - validate it"
→ Invokes ValidateSkill workflow
→ Checks SKILL.md against canonical format
→ Verifies TitleCase naming throughout
→ Verifies USE WHEN triggers are intent-based
→ Reports compliance issues with fixes
What ships with it
5 files 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.

Createskill is a skill published in the GitHub repository CarbeneAI/Forge (9 stars, last pushed 2mo ago), licensed MIT. It adds 60 tokens to every session and 645 once invoked, about $0.0002 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.
