Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00227 | $0.03813 |
| Opus 5.5 | $0.00091 | $0.01525 |
| Sonnet 5.5 | $0.00045 | $0.00763 |
| Haiku 4.5 | $0.00023 | $0.00381 |
Grade A, and why
icon-ops 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 324 lines — stays where its author put it; the contents beside it link to each section on GitHub.
icon-ops
Getting an icon onto a page is easy. Getting one that themes correctly, carries the right licence, matches the twelve icons beside it, and behaves for a screen reader is where the work actually is.
Helps with
An icon that won't change colour on hover, in dark mode, or when the theme
switches — almost always a hardcoded #000 in the file where currentColor
should be.
A UI where the icons "look off" without an obvious cause. Usually two icon sets mixed: different grid size, different stroke width, different corner language. Individually fine, together visibly wrong.
Choosing an icon set at the start of a project, when the choice is cheap, rather than after 60 icons are embedded.
Using a brand logo — GitHub, Google, a client's mark — and needing to know whether you actually may. The file licence does not answer this; trademark does.
Needing a logo for an arbitrary company that no icon set carries. That is a different category from icon sets — a runtime lookup by domain, not a committed glyph — with its own quota, caching and trademark consequences.
Icon-only buttons that a screen reader announces as "button", or announces twice. Both come from putting the accessible name in the wrong place.
Vendor SVGs carrying Inkscape/Figma metadata, fixed width/height that fights
CSS, and inline styles that resist theming.
Deciding between inline SVG, a <symbol> sprite, framework components, and an
icon font — and discovering too late that <img src="icon.svg"> cannot be
recoloured at all.
A sprite that renders nothing in production but worked locally (the external
<use> CORS trap).
Two inlined logos where the second one's gradient bleeds into the first. Both
files declared id="a"; the last definition in the document wins for the whole
page. Brand marks hit this constantly because they carry gradients.
Needing a mark in grey, knocked out of a dark header, or in one brand ink — and wanting to know whether to generate it or use the owner's published variant.
What ships with it
7 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.

icon-ops is a skill published in the GitHub repository 0xDarkMatter/claude-mods (76 stars, last pushed 11d ago), licensed MIT. It adds 227 tokens to every session and 3,813 once invoked, about $0.0009 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 2026-09-17.
