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 | $0.00049 | $0.00400 |
| Opus 5 | $0.00024 | $0.00200 |
| Sonnet 5 | $0.00010 | $0.00080 |
| Haiku 4.5 | $0.00005 | $0.00040 |
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.

SkillNote Dashboard
Show the user their SkillNote status for this project: which collection is active, how many skills synced, and where to manage them.
Resolve the host
HOST=$(cat ~/.skillnote/host 2>/dev/null | tr -d '[:space:]'); HOST=${HOST:-localhost}
API="http://${HOST}:8082"; WEB="http://${HOST}:3000"
Read the active collection
The active collection for this project is in ./.skillnote.json (a {"collections": [...]} file written by the collection picker). Synced skills live in ./.codex/skills/skillnote-*/.
cat ./.skillnote.json 2>/dev/null || echo '{"collections": []}'
ls -d ./.codex/skills/skillnote-* 2>/dev/null | sed 's#.*/skillnote-##' | sort
Report
Show a compact summary:
● SkillNote
Collection: <name from .skillnote.json, or "none — run the picker">
Skills: <count> (<comma-separated slugs>)
Web UI: <WEB>/collections
• Type /skills to invoke any synced skill
• Say "change collection" to switch ($skillnote:collection)
• Say "create a skill" to push a new one ($skillnote:skill-push)
If .skillnote.json is missing, tell the user no collection is active yet and that the picker runs automatically when they start codex (or they can say "change collection" now).
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.

skillnote is a skill published in the GitHub repository luna-prompts/skillnote (59 stars, last pushed 18d ago), licensed MIT. It adds 49 tokens to every session and 400 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (enumerates other installed skills).
