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 | $0.00031 | $0.01048 |
| Opus 5 | $0.00015 | $0.00524 |
| Sonnet 5 | $0.00006 | $0.00210 |
| Haiku 4.5 | $0.00003 | $0.00105 |
Grade A, and why
opengeni-skills 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 today.
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 — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Managing Skills
A Skill is a folder containing SKILL.md and supporting UTF-8 text files.
Use Skills for reusable instructions and procedures. Use Memory for facts and
outcomes, and workspace instructions for short always-on rules.
Read
skill_read works without a sandbox. Omit paths to read SKILL.md; specify
relative paths to read exactly those files. Include SKILL.md explicitly only
when you want it alongside other files. An empty paths list is not a default.
Read supporting files only when needed. Reads return current saved content;
you do not need to pin a version to follow a Skill.
To discover supporting files, call skill_read with listFiles: true and no
paths. This returns only relative paths (at most 128) and available revision
identity, never file bodies. Then request only the paths you need. Inventory
cannot be combined with paths and does not require sandbox checkout.
Find and install
Management tools are lazy: discover the relevant tool with tool search before
calling it. Use skill_search to find installed or available Skills and
skill_install to install a chosen source. Installation resolves source bytes
on the server; do not invent a source hash. Search does not install anything.
Installed guidance never grants credentials, tools, or additional permissions.
Keep the same operationId and original arguments when retrying an uncertain
install. A committed install replays before fetching the source again. Updates
must supply the reviewed installation version; do not substitute a newer value
merely to get past a conflict.
A skills.sh URL must match the current SKILL.md frontmatter name, not merely
the folder basename. If a link is stale or ambiguous, check the current name or
use the exact GitHub folder URL (https://github.com/owner/repo/tree/ref/path).
Create and edit
Use skill_save for small changes to any text file, not only SKILL.md.
Every Skill requires name and description in SKILL.md YAML frontmatter.
That file is the source of truth: edit its frontmatter to change how the Skill
appears in the index. There is no separately editable short description. Saves
derive the index metadata from the same revision; supporting-file edits leave
it unchanged. Invalid or missing frontmatter is an error, not a fallback.
Choose a fresh UUID skillId, set expectedRevisionId to null and
expectedScopeVersion to 1, and retain the operation id for retries.
Keep the main instructions focused; place longer references or scripts in
supporting files. Text files may have any extension or no extension.
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.

opengeni-skills is a skill published in the GitHub repository Cloudgeni-ai/opengeni (127 stars, last pushed today), licensed Apache-2.0. It adds 31 tokens to every session and 1,048 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 2026-09-10.
