skillnote

A SkillNote dashboard reports which SkillNote collection is active and which skills are synced into the project. SkillNote is a system for managing reusable instructions for coding agents.

In plain words
What is it for?
Use it when you want to see the active collection, count synced skills, find their names, or manage the collection.
Why use it?
It gives a quick view of the project's available skills and where to manage them, instead of checking project files manually.

Skill for Claude CodeCodex

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.

Made for: Claude Code, Codex.

Per session 49 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.
When invoked 400 The whole file, excluding the scripts and references it only reads on demand.
Security scan B 1 finding. Scan, not verified.
Origin original No closer match found in the catalogue.
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 it actually says

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).

Files

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.

Changes

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.
