emoji-lexicon-v7.md

Semantic emoji/icon lexicon for architecture, AI systems, documentation, and technical diagrams.

Icons function as semantic anchors — a visual DSL for system design that helps readers scan technical documents quickly.

Designed for: Markdown docs · architecture diagrams · draw.io / diagrams.net · Mermaid · Jupyter notebooks · technical blog posts.

This file consolidates every prior lexicon (v5, v6, the “category-first” variant) into one authoritative doc, recategorizes for sense, and adds a self-updating mechanism at the bottom. See Self Updating Doc and Maintenance Protocol before editing.

🧭 Design Principles

• Icons are semantic, not decorative.
• Prefer one canonical meaning per icon (the Canonical Icons table is the source of truth).
• An icon may appear in multiple categories — its canonical meaning still lives in one place.
• Separate Artifact vs Action vs State.
• Optimize for diagrams, markdown, and infographics.

⭐ Canonical Icons

The single source of truth. Each emoji appears at most once here (categories below may repeat it). ✅ marks an icon whose meaning is locked.

🗂️ Categories

An emoji may appear in more than one category. Each section lists its icons as an Icon · Name · Meaning table.

♻️ Self Updating Doc

A staging area you can edit freely. Drop emojis into the buckets below and ask me to “update the file emoji-lexicon-v7.md“ — I’ll process each bucket per the Maintenance Protocol at the very bottom.

Instructions

How to use the buckets (for you, the human):

• TODO — a holding pen. Candidates I’ve surfaced (or you’ve parked) that you haven’t decided on yet. From here you move emojis into TO BE ORGANIZED or TO BE CANONIZED.
• MORE LIKE THIS — drop an emoji here when you want more options like it. I’ll find lookalikes (by name, visual form, color, subject) and add them to TODO with a note on why they’re similar. The original stays so you can see the lineage.
• TO BE ORGANIZED — drop an emoji here and I’ll file it under one or more Categories above (and remove it from the bucket).
• TO BE CANONIZED — drop an emoji here (ideally with a note saying as what) and I’ll add it to the Canonical Icons table. No note / unclear note → I’ll write a short explanation in monospace parentheses right after the emoji.
• DON’T USE — emojis to avoid in generated docs. Listed as a standing reminder.
• TO BE DELETED — emojis to purge from the whole document.

You can scribble an inline note next to any emoji, e.g. 💉 (use this for DI instead of 🧲). I’ll try to honor inline notes first.

TODO

(empty — candidates I surface from MORE LIKE THIS land here for your review)

MORE LIKE THIS

(drop emojis here that you want more options like) ✨⭐🌟

TO BE ORGANIZED

_(drop emojis here to be filed under one or more categories)_ 🏚️ ## TO BE CANONIZED

(drop emojis here — with a note saying “as what” — to add to the Canonical Icons table)

DON’T USE

• 🚀 rocket — overused; do not use for deploy/launch/excitement. Prefer ⛴ / 📦 / 🏁 for delivery.
• 🎯 target / bullseye — avoid for “objective/goal”; prefer 🏰 (goal/stronghold) or 🏁 (milestone).

🗑️ TO BE DELETED

(emojis listed here get removed from every category, the canonical table, patterns, and quick-refs on the next update)

• (none yet)

🤖 Maintenance Protocol (instructions for Claude)

When the user says “update the file emoji-lexicon-v7.md“, process the Self Updating Doc and TO BE DELETED sections in this order:

1. Honor inline notes first. If the user wrote a note beside any emoji (anywhere in the buckets), do what it says before applying the generic rule for that bucket.
2. MORE LIKE THIS → for each emoji, brainstorm similar emojis along four axes — name, visual form, color, subject — name each candidate, and append them to TODO with a one-line “why similar”. Leave the originals in place (lineage). Do not auto-canonize or auto-file.
3. TODO → leave as a review pen. The user promotes these into TO BE ORGANIZED / TO BE CANONIZED themselves — don’t move them unless a note tells you to.
4. TO BE ORGANIZED → file each emoji under one or more existing Categories (multi-category is fine), then remove it from the bucket.
5. TO BE CANONIZED → add each to the Canonical Icons table with a meaning explaining as what. If the user left no note, or the note doesn’t make sense, generate a short explanation and place it in monospace/parentheses immediately after the emoji. Then remove it from the bucket.
6. DON'T USE → never emit these in any generated doc, and scrub them from the normal categories. Keep them listed here as a reminder.
7. TO BE DELETED → remove these emojis from every category, the Canonical Icons table, patterns, grammar, and quick-refs. Then clear the bucket.
8. Keep the Canonical table unique — an emoji appears at most once there (categories may repeat it).
9. Re-version when drastic. Per the global CLAUDE.md rules, if a pass changes the doc drastically, bump to emoji-lexicon-v8.md (keep the base name) and repoint the CLAUDE.md reference.
