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 A, and why

update-skills 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 7d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/apply-update.sh, scripts/check-updates.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Update Skills

Check for updates to locally installed skills by fetching the latest from kimgoetzke/coding-agent-configs on GitHub and comparing against the local skills directory.

Configuration

  • Remote repo: https://github.com/kimgoetzke/coding-agent-configs.git
  • Scripts location: Bundled in this skill's scripts/ directory

Target directory by tool

Tool Default target directory
Claude Code ~/.claude/skills
Copilot ~/.copilot/skills
Pi ~/.pi/agent/skills

If you cannot determine which tool you are, ask the user.

Workflow

1. Determine target directory

Set the target directory based on the table above. Use the variable TARGET_DIR in subsequent steps.

Also resolve SKILL_DIR to the absolute path of this locally installed skill directory. Typical values:

  • Claude Code: ~/.claude/skills/update-skills
  • Copilot: ~/.copilot/skills/update-skills
  • Pi: ~/.pi/agent/skills/update-skills

2. Check for updates

Run the check script:

bash "$SKILL_DIR/scripts/check-updates.sh" "$TARGET_DIR"

3. Parse the output

The script outputs one line per skill with a status prefix:

Prefix Meaning
UP_TO_DATE:<name> No changes
CHANGED:<name> Files differ — diff follows until END_DIFF line
MISSING_LOCALLY:<name> Exists in repo but missing locally
ALL_UP_TO_DATE No updates available at all

Skills that exist locally but not in the remote repo are ignored.

4. Present results to the user

  • If ALL_UP_TO_DATE: tell the user all skills are up to date and stop
  • Otherwise, FOR EACH CHANGED or MISSING_LOCALLY skill:
    • List the skill name and summarise what changed (files added/removed/modified)
    • Show the diff in a code block
    • Ask the user if they want to apply this update

Files

What ships with it

2 files 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.
