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 | $0.00087 | $0.02930 |
| Opus 5.5 | $0.00035 | $0.01172 |
| Sonnet 5.5 | $0.00017 | $0.00586 |
| Haiku 4.5 | $0.00009 | $0.00293 |
Grade A, and why
agents-sdk scanned grade A with 1 finding 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Custom routing: use `getAgentByName(env.MyAgent, "instance-id")` then `agent.fetch(request)`. This is a copy
100% identical to agents-sdk — 93 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.

agents-sdk is a skill published in the GitHub repository is-bo/fullstack-forge-skill (2 stars, last pushed 3d ago), licensed Apache-2.0. It adds 87 tokens to every session and 2,930 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). It is 100% identical to agents-sdk, differing in 93 lines, and is treated as a copy.
