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 | $0.00050 | $0.00278 |
| Opus 5 | $0.00025 | $0.00139 |
| Sonnet 5 | $0.00010 | $0.00056 |
| Haiku 4.5 | $0.00005 | $0.00028 |
Grade A, and why
memory-add-link 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 9d 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
memory-add-link
Hard rule
Never invent a summary.
If the user did not provide a summary (or an explicit “summarize as: …”), call memory_add_link without summary so others can contribute later.
Steps
- Extract
url(must behttp://orhttps://). - Optional fields only if user provided them:
title,summary,tags. - Call MCP
memory_add_link. - Report
id, whetherneeds_summaryis true.
Examples
User: “Save https://example.com/okf”
→ memory_add_link with url only.
User: “Save https://example.com — it’s Google’s OKF blog, tags: reading”
→ url + summary from their words + tags ["reading"].
After
If needs_summary, offer: “I can list other links waiting for a summary” → skill memory-contribute-summary.
$ARGUMENTS
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.

memory-add-link is a skill published in the GitHub repository MickaelV0/demo-mcp (0 stars, last pushed 1mo ago), licensed MIT. It adds 50 tokens to every session and 278 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.
