Validate a container image change via backdoor deployment. An agent skill from microsoft/Docker-Provider.

  • Works in 3 steps: Obtain Build + Deploy Production Image… → Deploy Test Image (after build completes) → Compare Results
  • : deploying test image to a cluster
  • SKILL.md covers Required Inputs, Derived Values, Build Pipeline and General Rules, plus 2 more sections
  • Calls az, kubectl and helm; reaches dev.azure.com

What it does

Backdoor Deployment is an agent skill from microsoft/Docker-Provider, published by the product's own GitHub organization. Validate a container image change via backdoor deployment. Use when: deploying test image to a cluster, comparing data volume between deployments, comparing resource consumption, backdoor deploy, validate container image, image regression testing, build and deploy branch.

Its SKILL.md is about 7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Deployment, Containers and QA and bug reports. It works with Microsoft Azure and Kubernetes. The repository describes itself as: Azure Monitor for Containers.

When your agent uses it

  • : deploying test image to a cluster
  • Comparing data volume between deployments
  • Comparing resource consumption
  • Backdoor deploy

Example prompts

  • “/backdoor-deployment”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Obtain Build + Deploy Production Image (parallel)
  2. Deploy Test Image (after build completes)
  3. Compare Results

What it can do on your machine

Read from SKILL.md and the folder at commit 586b305. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • az
    • kubectl
    • helm
    • jq
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • dev.azure.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Backdoor Deployment loads about 7k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 2,676 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~73
When it runs · the whole SKILL.md, loaded when a task matches
~7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,676 words (~6,958 tokens).

“Validates a container image change by deploying the current production image, collecting baseline data, then deploying the test image (from a CI build) and comparing data volume and resource consumption. No regressions = pass.”
