What it does
Helm Chart is an agent skill from astronomer/airflow-chart. Use for Helm chart work - creating charts, modifying existing charts, values design, testing. For the Astronomer airflow-chart repository, this is the umbrella chart whose single dependency is the upstream Apache Airflow chart.
Its SKILL.md is about 6.4k 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 Data & Analytics, covering Container orchestration and Data pipelines and ETL. It works with Apache Airflow, Helm, Kubernetes and Astro. The repository describes itself as: A Helm chart to install Apache Airflow on Kubernetes.
When your agent uses it
- Helm chart work - creating charts
- Modifying existing charts
Example prompts
- “/helm-chart”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Reference Helm Chart Best Practices
- Use helpers for reusable patterns
- Provide sensible security defaults
- Include comprehensive values documentation
- Add values.schema.json for IDE support
- All changes must pass pre-commit checks with prek run --all-files
What it can do on your machine
Read from SKILL.md and the folder at commit a204c9c. 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:
helmkubectlmakeuv
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:
charts.bitnami.comimg.shields.iojson-schema.orggithub.com
Also links to:
helm.sh
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
TEST_TOKENDB_PASSWORD
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Helm Chart loads about 6.4k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 1,035 words of instructions outside code blocks.
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 1,035 words (~6,382 tokens).
“This repository (astronomer/airflow-chart) is Astronomer's Helm chart for Apache Airflow. The chart is named airflow (see Chart.yaml), but the repo and the packaged release are airflow-chart.”
