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

sync-from-claude 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 9d 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.

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.

What it actually says

Sync from Claude

Sync from Claude Code using the skrills MCP server.

Use the mcp__plugin_skrills_skrills__sync-from-claude tool with:

  • to: Target agent (codex, cursor, or copilot). Default: codex
  • include_marketplace: Include marketplace skills (default: false)
  • dry_run: Preview changes without writing

Parse $ARGUMENTS for:

  • --to <agent> or -t <agent>: Target agent (default: codex)
  • --include-marketplace: Include marketplace skills
  • --dry-run or -n: Preview mode

This reads from ~/.claude/:

  • Skills from SKILL.md files

And syncs to the target directory:

  • Codex: ~/.codex/skills/ (Codex discovery root)
  • Cursor: .cursor/ directory (agents, rules, skills)
  • Copilot: ~/.config/github-copilot/instructions/

Report:

  • Number of skills copied
  • Number of skills skipped
  • Names of synced skills

Handle errors:

  • If Claude directory doesn't exist: Report and exit cleanly
  • If target directory doesn't exist: Offer to create 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.
