What it does
YAML Master is an agent skill from jeremylongshore/tons-of-skills-marketplace. Execute proactive YAML intelligence: automatically activates when working with YAML files. Use when appropriate context detected. Trigger with relevant phrases based on skill purpose.
Its SKILL.md is about 650 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts, reference files and assets (for example `assets/README.md`, `references/README.md` and `references/SKILL.full.md`). Compatibility notes: Designed for Claude Code
It sits in DevOps & Cloud. It works with Kubernetes and GitHub Actions. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
When your agent uses it
- Appropriate context detected
- With relevant phrases based on skill purpose
Example prompts
- “/yaml-master”
Requirements
- Docker
- Compatibility (from SKILL.md): Designed for Claude Code
- Pre-approved tools (allowed-tools): Read, Write, Edit, Grep, Glob, Bash(general:*), Bash(util:*)
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Parse and validate YAML syntax (identify the first breaking error and its location).
- Normalize formatting (indentation, quoting) without changing semantics.
- Validate structure against the target system’s expectations (keys, types, required fields).
- Identify risky patterns (duplicate keys, ambiguous scalars, anchors used incorrectly).
- Output a minimal patch plus a short validation checklist (what to run next).
What it can do on your machine
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGrepGlobBash(general:*)Bash(util:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/, which the agent can run.
Shell commands in SKILL.md call:
kubectl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
yaml.orgdocs.github.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.
Compatibility
Designed for Claude Code
From compatibility in the SKILL.md frontmatter.
Context cost
YAML Master loads about 654 tokens when it runs, and up to ~5k if it reads all its reference files. Until then it costs about 49 tokens; SKILL.md has 271 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); the scripts in this folder are not scanned.

YAML Master
Proactive YAML intelligence: validate syntax, enforce consistent formatting, and keep configuration files schema-correct (Kubernetes, GitHub Actions, Docker Compose, and similar).
Overview
This skill activates when working with .yml/.yaml files to detect structural issues early (indentation, anchors, type mismatches), and to produce safe, minimal edits that keep CI/config tooling happy.
Prerequisites
- The YAML file(s) to inspect and their intended target (e.g., Kubernetes, GitHub Actions, Compose)
- Any relevant schema or constraints (when available)
- Permission to edit the file(s) (or to propose a patch)
Instructions
- Parse and validate YAML syntax (identify the first breaking error and its location).
- Normalize formatting (indentation, quoting) without changing semantics.
- Validate structure against the target system’s expectations (keys, types, required fields).
- Identify risky patterns (duplicate keys, ambiguous scalars, anchors used incorrectly).
- Output a minimal patch plus a short validation checklist (what to run next).
Output
- Corrected YAML with minimal diffs
- A concise list of issues found (syntax vs schema vs best practice)
- Follow-up validation commands appropriate for the target (e.g.,
kubectl apply --dry-run=client, CI lint)
Error Handling
- If the schema/target is unknown, ask for the target system and apply syntax-only fixes first.
- If the YAML is valid but tooling still fails, surface the exact downstream error and reconcile expectations.
Examples
Example: Fix an indentation/syntax error
- Input: a workflow with a mis-indented
steps:block. - Output: corrected indentation and a note on which job/step was affected.
Example: Convert JSON to YAML safely
- Input: a JSON config blob.
- Output: YAML with explicit quoting where necessary to avoid type surprises.
