Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00012 | $0.00310 |
| Opus 5 | $0.00006 | $0.00155 |
| Sonnet 5 | $0.00002 | $0.00062 |
| Haiku 4.5 | $0.00001 | $0.00031 |
Grade A, and why
icon-lookup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Icon Lookup
Search for icons by name or identify an actual PUA character. Uses the Nerd Fonts icon database.
Instructions
If the argument contains PUA characters (codepoints in U+E000-U+F8FF or U+F0000+), identify them:
python3 ${CLAUDE_PLUGIN_ROOT}/scripts/identify-icons.py -c "$ARGUMENTS"
Otherwise, search by name:
python3 ${CLAUDE_PLUGIN_ROOT}/scripts/lookup-icon.py "$ARGUMENTS"
Present results showing:
- Icon name (e.g.,
nf-fa-star) - Codepoint (e.g.,
U+F005) - Whether it's in the filtered BMP PUA range (U+E000-U+F8FF) or the working Supplementary PUA-A range (U+F0000+)
- For filtered icons: placeholder syntax
{{U+F005}}or{{nf-fa-star}} - For working icons: note they can be written directly
If no results found, suggest different search terms or the Nerd Fonts cheat sheet.
Examples
/icon-lookup git→ search for git-related icons/icon-lookup → identify the character (nf-md-github)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

icon-lookup is a command published in the GitHub repository malob/nix-config (462 stars, last pushed yesterday), licensed MIT. It adds 12 tokens to every session and 310 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
