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 | $0.00023 | $0.00401 |
| Opus 5.5 | $0.00009 | $0.00160 |
| Sonnet 5.5 | $0.00005 | $0.00080 |
| Haiku 4.5 | $0.00002 | $0.00040 |
Grade A, and why
find-font 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 17d 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
Find font
Standalone browsing of the local font catalog, outside any design task —
"what do I have that's warm and editorial," "find me a technical
monospace," etc. Read ${CLAUDE_PLUGIN_ROOT}/skills/find-font/references/ consulting.md and ${CLAUDE_PLUGIN_ROOT}/skills/find-font/references/ classification.md and follow them; this skill is the trigger, those
files are the mechanics.
Arguments (required): $ARGUMENTS — a free-text mood/structure/use-case
description, e.g. "warm editorial serif for body text".
Steps
- Read
~/.claude/local-font-sources/catalog/*.jsonand matchstatus: classifiedfamilies against$ARGUMENTSonstructure,mood, anduse_cases(perclassification.md's tag vocabulary and matching guidance). - If nothing classified fits, scan
~/.claude/local-font-sources/ index.jsonfor plausible unclassified families — matching on the family name andbundled_descriptionwhere one exists, not name alone — and classify the top 2-3 before answering. Don't report "nothing found" when unclassified candidates exist; also don't force a match when nothing in the index is actually plausible. - Report the best match: family, source (
namefromconfig.json), license, and why (the matching tags/reasoning) — plus the runner-up if one exists.
This is a lookup, not a design decision — it doesn't copy files, write
@font-face, or touch any project. That embedding step only happens
inside a real design task; see consulting.md.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

find-font is a skill published in the GitHub repository a8cteam51/claude-code-plugins (5 stars, last pushed 2d ago), licensed MIT. It adds 23 tokens to every session and 401 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-29.
