What it does
Blueprint Style Counter is an agent skill from receptron/mulmoterminal. Prove the style bites: write texts that deliberately break the guide and confirm chaff reports them.
Its SKILL.md is about 490 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 Agent Workflows. The repository describes itself as: Run multiple Claude Code and Codex sessions in parallel — a browser terminal grid that shows which agent needs you. Local, tmux-backed, MIT. The licence is MIT.
When your agent uses it
- Agent Workflows work in your project
Example prompts
- “/blueprint-style-counter”
What it can do on your machine
Read from SKILL.md and the folder at commit b3f6ff0. 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:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Blueprint Style Counter loads about 488 tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 294 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.

Show that the style catches something
A style that no bad text can trip is a style nothing checks. This is the documents' version of breaking the code to see a test go red.
Write a few short texts in .blueprint/counter/, in the same language and kind as the models. Each
breaks the guide on purpose, and each in a different way: a long run-on sentence, the wrong sentence
ending mixed in, a heading the next sentence merely repeats, padding and cushion phrases, a term spelled
against STYLE.md. Keep them plausible — the kind of draft a real writer produces on a bad day.
List them in .blueprint/counter.json:
[{ "file": "run-on.md", "breaks": "語調と文末: 一文に三つ以上のことを詰めない" }]Done when
node <usecase pack>/checks/counter.mjs (with BLUEPRINT_BASE and BLUEPRINT_USECASE set to the pack folders from your prompt) passes: chaff reports something in every counter text,
at least three different rules fire across them, and every rule chaff.yaml turns on fires in at least one of
them (a note counts). A consistency rule (contractions, the Oxford comma, heading case) reports only against a
clear majority, so its text must lean one way and break it once or twice — a text split evenly shows nothing. Never
write in the report that a rule "does not react" unless a text built to trip it was run and stayed silent. If a text raises nothing, the style does not reach what
it breaks: either that part belongs in STYLE.md only (a machine cannot see it — say so in the report),
or a rule is too loose or off — change it in chaff.yaml and record the new level and its reason in
.blueprint/rule-decisions.json. This step's check runs the rules step's check again first, so a change
that makes the models fail their own style, or a change without a reason, stops here.
