What it does

Google Developer Style is an agent skill from OpenAgentsInc/openagents. Apply the Google Developer Documentation Style Guide to user-facing docs, READMEs, AGENTS.md, and commit messages. Use when writing or reviewing prose in this repo.

Its SKILL.md is about 630 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 Development, covering Commit messages, Technical documentation and Agent instruction files. The licence is Apache-2.0.

When your agent uses it

  • Reviewing prose in this repo
  • Tasks that involve Commit messages
  • Tasks that involve Technical documentation

Example prompts

  • “/google-developer-style”

What it can do on your machine

Read from SKILL.md and the folder at commit ad9f02f. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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):

    • developers.google.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

Google Developer Style loads about 630 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 328 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~630

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.

Google Developer Documentation Style

Use this skill when you write or review user-facing documentation, READMEs, AGENTS.md, and commit messages for OpenAgents.

How to use this skill

Apply these rules to the text you produce or edit. When a rule would make something less clear, break the rule and stay consistent.

Voice and tone

  • Be conversational and friendly, but not frivolous or overly casual.
  • Write as a knowledgeable friend who understands what the developer wants to do.
  • Avoid jargon, buzzwords, clichés, metaphors, ableist language, and pop-culture references.
  • Avoid exclamation marks and over-polite phrases such as "please" or "please note."
  • Avoid filler words like "simply," "just," "it's easy," or "quickly" in procedures.
  • Avoid phrasing like "let's do something" or "we" for the reader; speak to the reader with "you."

Language and grammar

  • Use active voice. Make clear who performs the action.
  • Use second person ("you") for the reader.
  • Use present tense.
  • Use standard American spelling and punctuation.
  • Put conditions before instructions, not after.
  • Use serial commas.
  • Do not use ampersands (&) as conjunctions in body text or headings.

Formatting

  • Use sentence case for all headings, titles, and navigation.
  • Use code font for code, filenames, class names, method names, HTTP status codes, placeholders, and user input.
  • Use bold for UI elements and run-in headings.
  • Use italics sparingly, mainly when introducing or defining terms.
  • Underline only for link text.
  • Do not override global font styles.

Lists

  • Use numbered lists for sequences and procedures.
  • Use bulleted lists for related but unordered items.
  • Use description lists for related pairs of data.
  • Keep list items parallel in structure.
  • Put code in text in code font.
  • Use descriptive link text. Avoid "click here" or "this page."
  • Use unambiguous date and time formatting.
  • Provide alt text for images.

Banned patterns

  • "Dude!" / "This is awesome!"
  • "It's that simple" / "It's easy" / "simply"
  • "Please" in instructions
  • "At this time" / "please note"
  • "Let's" as an imperative to the reader
  • All-caps or title-case headings
