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 | $0.00045 | $0.00654 |
| Opus 5.5 | $0.00018 | $0.00262 |
| Sonnet 5.5 | $0.00009 | $0.00131 |
| Haiku 4.5 | $0.00005 | $0.00065 |
Grade A, and why
create-skill 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 2mo 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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create Skill
Follow these steps to predictably convert a Gemini Gem or generic agentic prompt into a properly formatted structural skill for the Hypergraph Coding Agent Framework.
When to use this skill
- When the user provides an agentic prompt, a "Gemini Gem", or a raw textual description and asks you to create a "skill" out of it.
- When the user runs the
/hyper-create-skillslash command.
How to use it
-
Gather Inputs:
- Ensure you have the full content of the agentic prompt / Gemini Gem.
- Determine a short, hyphen-separated name for the skill (e.g.,
code-revieworapi-design). - Determine a concise, third-person description of what the skill does (e.g., "Generates unit tests for Python code using pytest conventions.").
-
Create the Directory Structure:
- Create the primary skill folder at
.agents/skills/<skill-name>/(Workspace scope) or~/.gemini/antigravity/skills/<skill-name>/(Global scope). Default to workspace scope unless otherwise specified. - Create the standard optional subdirectories:
scripts/(for helper scripts)examples/(for reference implementations)resources/(for templates and assets)
- Create the primary skill folder at
-
Draft the SKILL.md File:
- Create the main instruction file at the root of the skill folder:
SKILL.md. - Mandatory Frontmatter: Start the file with the strict YAML frontmatter exactly as shown in this skill's
resources/SKILL_TEMPLATE.md. - Structure the Content: Adapt the prompt into the standard markdown format using the template as a guide. Ensure you include the
## When to use this skilland## How to use itsections.
- Create the main instruction file at the root of the skill folder:
-
Organize and Create Auxiliary Files:
- Identify if the input prompt/Gem includes secondary materials (scripts, examples, JSON schemas, templates, etc.).
- Create any identified script files in the
scripts/subdirectory (ensure executable permissions if applicable). - Create any identified example files in the
examples/subdirectory under the new skill. - Create any identified template or asset files in the
resources/subdirectory under the new skill. - Explicitly reference these auxiliary files from within the newly generated
SKILL.mdfile using relative paths or explicit instructions.
What ships with it
2 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.

create-skill is a skill published in the GitHub repository tjmustard/Hypergraph-Coding-Agent-Framework (2 stars, last pushed 1mo ago), licensed MIT. It adds 45 tokens to every session and 654 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.
