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

create-docker-skill 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 today.

The scan reads SKILL.md. This mod also ships 1 executable file (execute.py), 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.

What it actually says

Follow the create-docker-skill skill workflow to scaffold a compliant agent skill that depends on containerized runtimes (Docker, Nextflow, HPC).

Inputs

  • $ARGUMENTS — optional skill name or use-case description. Omit to start with discovery.

Steps

  1. If $ARGUMENTS provides a skill name, use it to seed the discovery phase
  2. Follow the create-docker-skill phased workflow: determine container runtime and workflow type, gather environment check requirements, design pre-flight validation and subprocess execution scaffolding, then generate the skill directory
  3. Report the created skill path and Docker environment setup instructions

Output

Skill directory with SKILL.md containing pre-flight environment checks, subprocess execution patterns, security-override config, and Docker-aware error handling.

Edge Cases

  • If $ARGUMENTS is empty: begin with discovery — do not assume Docker is available
  • If Docker is not installed in the target environment: generate graceful degradation
  • If the workflow uses HPC or Nextflow instead of Docker: adapt scaffolding accordingly
Files

What ships with it

60 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.
