What is docker-helper?

Instructions and scripts for inspecting Docker containers, storage volumes, and Compose services for Pixel Detective and Dev Graph.

Use it to check Docker availability, list containers and volumes, inspect storage, and view or manage the named project services.

It shows which services and stored data exist or are stopped without requiring heavy services to run.

docker-helper — Skill for Claude Code and Codex by rm2thaddeus

Install

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.

Any agent

npx skills add rm2thaddeus/Pixel_Detective --skill docker-helper

Clone the repo

git clone --depth 1 https://github.com/rm2thaddeus/Pixel_Detective

Made for: Claude Code, Codex.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00044	$0.00397
Opus 5.5	$0.00018	$0.00159
Sonnet 5.5	$0.00009	$0.00079
Haiku 4.5	$0.00004	$0.00040

Security

Grade A, and why

docker-helper 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/docker_inventory.ps1), 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

Docker Helper

Use this skill to read Docker state for the repo and list stored data sources.

Quickstart

Status + capabilities: powershell -ExecutionPolicy Bypass -File skills\\docker-helper\\scripts\\docker_inventory.ps1 -Action status -ListCapabilities

Workflow

Confirm Docker is available

docker version
docker compose version

Inspect containers and compose services

docker ps -a
docker compose ps

Inspect volumes and storage

docker volume ls
docker system df
For repo volumes, run:
- docker volume inspect qdrant_storage
- docker volume inspect neo4j_data

Report findings

Note which services are up, stopped, or missing.
Identify which volumes exist and their mountpoints.

Script

Run: powershell -ExecutionPolicy Bypass -File skills\docker-helper\scripts\docker_inventory.ps1
With volume details: -ShowVolumes
List capabilities: -ListCapabilities
Action examples:
- -Action status
- -Action start -Target neo4j
- -Action stop -Target dev_graph_api
- -Action restart -Target qdrant_db
- -Action logs -Target dev_graph_ui -LogsTail 200

Notes

This skill can start/stop/restart services via docker compose in the repo root.
docker compose actions auto-detect the repo root (by locating docker-compose.yml).
The compose file may warn that the version field is obsolete; ignore the warning.

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.

docker-helper is a skill published in the GitHub repository rm2thaddeus/Pixel_Detective (21 stars, last pushed 8mo ago), licensed MIT. It adds 44 tokens to every session and 397 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
