skillnote

A command that displays the SkillNote dashboard, including the active collection, synchronized skills, web address, and available commands. SkillNote is a registry and dashboard for shared coding-agent instructions.

In plain words
What is it for?
Checking the selected collection, counting and listing local SkillNote skills, showing the dashboard URL, and listing commands for changing collections or publishing skills.
Why use it?
It gives a quick view of what is configured and synchronized without opening several files or remembering the server address.

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.

Clone the repo

Per session 13 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 444 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

skillnote scanned grade B 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 2d 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.

Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.

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.
