container-build-assessment

container-build-assessment is a skill for Claude Code from ivegamsft/basecoat. It costs 95 tokens per session (331 once invoked), scanned A, original, MIT.

A Docker build readiness assessment for an application. Docker packages an application and its dependencies into a container so it can run consistently in different environments.

In plain words
What is it for?
Use it to inspect a Dockerfile, estimate the resulting image size, assess build dependencies and security risks, and produce a consolidated report.
Why use it?
It reveals issues in a Dockerfile, dependency footprint, expected image size, and security posture before containerisation or deployment. The results are returned as structured JSON for automation.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./scripts/orchestrate-skill-scripts.ps1 `.

Good fit Use it to inspect a Dockerfile, estimate the resulting image size, assess build dependencies and security risks, and produce a consolidated report.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

container-build-assessment 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 4d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/analyze-dockerfile.ps1, scripts/estimate-build-size.ps1, scripts/scan-dependencies.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

Container Build Assessment

This skill runs four scripts in order to produce a structured container build assessment.

Usage

Run all steps:

./scripts/orchestrate-skill-scripts.ps1 `
  -SkillPath skills/container-build-assessment/SKILL.md `
  -DockerfilePath ./Dockerfile `
  -AppRoot .

Run one step:

./scripts/orchestrate-skill-scripts.ps1 `
  -SkillPath skills/container-build-assessment/SKILL.md `
  -Step analyze-dockerfile `
  -DockerfilePath ./Dockerfile

Output

The orchestrator returns step-by-step JSON plus a final consolidated result.

Files

What ships with it

5 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.
