What is dash_skills GEMINI.md?

Instructions for creating and maintaining modular skill packages for the Gemini CLI and other AI agents. A skill package normally centers on a SKILL.md file, with optional scripts, references, and assets.

Writing skill metadata and instructions, organizing skill folders, keeping Markdown concise and readable, and maintaining existing skills.

It gives authors a consistent structure and writing guidance. This makes skills easier for agents to discover, read, and apply within limited context.

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	$0.00565	$0.00565
Opus 5.5	$0.00226	$0.00226
Sonnet 5.5	$0.00113	$0.00113
Haiku 4.5	$0.00056	$0.00056

Security

Grade A, and why

dash_skills GEMINI.md 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.

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.

Authoring and Maintaining Skills

This repository contains a curated collection of "skills" for the Gemini CLI and other AI agents. Skills are modular, self-contained packages that extend an agent's capabilities with specialized knowledge and workflows.

Skill Structure

Each skill is located in skills/<skill-name>/ and must contain a SKILL.md file.

skills/<skill-name>/
├── SKILL.md (required)
├── scripts/ (optional)
├── references/ (optional)
└── assets/ (optional)

`SKILL.md`

The SKILL.md file is the heart of the skill. It contains:

YAML Frontmatter: Metadata including name and description. The description is critical as it's used by the agent to decide when to trigger the skill.
Markdown Instructions: Procedural knowledge, examples, and workflows.

Authoring Guidelines

Be Concise: Agents have limited context windows. Focus on information the agent doesn't already have.
Imperative Tone: Use imperative or infinitive form for instructions (e.g., "Use isA<T>() for type checks" rather than "You should use...").
80-Column Rule: Wrap all text in .md files to 80 characters. This improves readability in terminals and split-pane editors.
Examples Over Explanations: Provide clear, realistic code snippets or interaction examples.
Tool Integration: If a skill uses scripts in scripts/, explain how the agent should invoke them.
YAML Frontmatter: Use YAML folded block scalars (|-) for long descriptions to keep lines under 80 characters.

Maintaining Skills

Keep Descriptions Accurate: The frontmatter description is the only thing the agent reads before activating the skill. Ensure it clearly states the "when to use" scenarios.
Test Scripts: Ensure all scripts in scripts/ are executable and produce LLM-friendly output.
Update References: Move detailed documentation or large schemas to the references/ folder to keep the main SKILL.md lean.

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.
