What it does

Blueprint Compare Pair is an agent skill from receptron/mulmoterminal. Pair every article of the old version with its article in the new one, and say whether each changed, was added or was removed — writing .blueprint/comparison.json and changing no document.

Its SKILL.md is about 680 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-compare-pair”

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:

    • sh
    • 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 Compare Pair loads about 678 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 343 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~678

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.

description
Pair every article of the old version with its article in the new one, and say whether each changed, was added or was removed — writing .blueprint/comparison.json and changing no document.

Pair the articles of the two versions

.blueprint/answers.json names the old version (old), the new version (new) — one file each — and what the person wants looked at first (focus, may be empty). Read both in full. The person may not be an engineer: say what you do in plain words.

Change nothing in the repository: neither version is touched. Write only under .blueprint/.

Find the articles

Run sh <base pack>/checks/chaff.sh tree <file> --format json on each version. Every node whose kind is article is one article; its address ("4") is how you name it below, and attrs.label (第4条, Article 4) is how the person reads it. The check uses the same tree, so an article chaff does not read as one is not yours to pair.

Pair them

For each article of the old version, find the article of the new version that carries the same provision — by what it says, not by its number: a provision that moved or was renumbered (old 第9条 is new 第8条) is one pair. Then write .blueprint/comparison.json:

json
{ "rows": [
  { "old": "1", "new": "1", "change": "same" },
  { "old": "4", "new": "4", "change": "changed", "what": "委託料が月額200,000円から220,000円になった" },
  { "old": null, "new": "5", "change": "added", "what": "毎月5日までの報告の条が足された" },
  { "old": "8", "new": null, "change": "removed", "what": "成果物の扱いの条が消えた" },
  { "old": "9", "new": "8", "change": "same" }
] }
  • same / changed — both old and new. changed needs what: one line, in the person's language, saying what is different, with the words or numbers from both versions. A change in a paragraph or an item is a change to the article that holds it.
  • added — only new; removed — only old. A what saying what the article is about helps the person.
  • Every article of each version appears in exactly one row.

Whether a pair is same or changed is not a judgement: the check compares the two articles' text (spacing aside, and leaving out the article's own number) and refuses a same whose text differs and a changed whose text does not. When you pair two articles that the check calls different but you think the change is trivial (punctuation, a character's width), it is still changed: say so in what.

Done when

node <usecase pack>/checks/comparison.mjs (with BLUEPRINT_BASE and BLUEPRINT_USECASE set to the pack folders from your prompt) passes. It writes .blueprint/comparison.txt, the pairing a person reads before the table.
