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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00029 | $0.00260 |
| Opus 5 | $0.00015 | $0.00130 |
| Sonnet 5 | $0.00006 | $0.00052 |
| Haiku 4.5 | $0.00003 | $0.00026 |
Grade A, and why
demo-research-brief 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 12d 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.
What it actually says
Example: Demo Research Brief
Example skill: This bundle exists to demonstrate Open SSR. It is intentionally small and is not presented as a production research methodology.
Use it to test the complete registry path:
- List or search for
demo-research-brief. - Describe its registry metadata.
- Retrieve
SKILL.mdandtemplates/brief.mdwith checksums. - Install it into a configured scratch skills directory.
- Confirm the installed files remain inside that directory.
Example workflow
- Identify a topic and audience.
- Collect public source notes.
- Summarize the key claims.
- Flag uncertainty and missing evidence.
- Fill in
templates/brief.mdwith a concise brief and next steps.
Completion criterion
The example is complete when a fresh client can retrieve both files, verify their checksums, install them into a scratch skills root, and read the installed SKILL.md.
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.

demo-research-brief is a skill published in the GitHub repository cobibean/shared-skills-registry-mcp (7 stars, last pushed 2mo ago), licensed MIT. It adds 29 tokens to every session and 260 once invoked, about $0.0001 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.
