What it does

Plain English is an agent skill from Fallout-build/Fallout. Write clear, plain English for developer-facing prose aimed at an international audience. Use this skill whenever you draft or review a pull request description, commit message, changelog or release-note entry, issue report, code-review comment, or README / docs prose — especially in open-source repositories where many contributors read English as a second language. Trigger it even when the user does not say "plain English": any time the deliverable is short technical writing that other people will read, apply…

Its SKILL.md is about 2k 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 Plain language and style rules, Changelog and release notes and Pull requests. The repository describes itself as: ☢️ Fallout — The C/.NET Build System.

When your agent uses it

  • Review a pull request description
  • Release-note entry
  • Code-review comment
  • README / docs prose — especially in open-source repositories where many contributors read English as a second language

Example prompts

  • “plain English”
  • “/plain-english”

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Lead with the ask. First sentence says what changed and why. Everything
  2. Match length to substance. A one-line fix gets a one-line description.
  3. Cut filler. Drop preamble, restating the title, hedging, marketing words
  4. One idea per sentence. Do not chain clauses with em-dashes or semicolons.
  5. No idioms or figurative language. Say it literally.
  6. Define jargon on first use, or link it. Terms like "shim", "sentinel",
  7. Gloss every cross-reference. A bare #257 tells the reader nothing.
  8. Prefer short, common words.

What it can do on your machine

Read from SKILL.md and the folder at commit c1fd6e5. 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:

    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.

    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

Plain English loads about 2k tokens when it runs. Until then it costs about 167 tokens; SKILL.md has 1,022 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~167
When it runs · the whole SKILL.md, loaded when a task matches
~2k

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 1,022 words (~2,011 tokens).

“Goal: text a non-native English reader understands on the first pass, without a dictionary and without guessing at idioms. Applies to PR descriptions, commit messages, changelogs, release notes, issue reports, review comments, and docs — for new text and for…”
