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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high YARA Match · line 3 YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).Fix: Remove offensive tool references and exploit code. Legitimate agent skills should not contain penetration testing tools, exploit frameworks, or reconnaissance utilities.
What it costs to keep this loaded
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 | $0.00083 | $0.02759 |
| Opus 5 | $0.00042 | $0.01380 |
| Sonnet 5 | $0.00017 | $0.00552 |
| Haiku 4.5 | $0.00008 | $0.00276 |
Grade A, and why
brand-identity 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 11d 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brand Identity — Define the Foundation, Not the Pixels
This skill emits the brand book — logo brief, color system, type system, usage rules — and a machine-readable design-tokens.json that design consumes. You write the rules every later pixel must obey; you do not paint the live UI.
A brand identity with nothing checkable behind it is a mood board. The bar here is a brand book that compiles: roles named, every color carrying four channels, contrast pairs proven against WCAG, and a tokens file that scripts/verify.sh can validate.
All four parts ship together — logo brief, color system, type system, usage guidelines with the tokens export. A part missing its bar is incomplete, not "lite".
The one-line boundary test: "define what our brand looks like everywhere" → here. "make this surface look premium" → design.
Logo brief
Specify a system, not a single picture. The mark must survive from favicon to billboard, in color and in one ink.
- Variation set — primary (horizontal lockup), stacked (vertical, for square/tight slots), mark-only (the symbol alone, for avatars/favicons), monochrome (single-ink: black, white-knockout). A logo with no mono version fails the moment it lands on a colored background or a fax. Test the mono version first; if it dies in one color, the design is too fragile.
- Clear space — define it relative to the mark, not in fixed px, so it scales: clear space = the cap-height (or x-height of the mark) on all four sides. Nothing intrudes inside it.
- Minimum size — below this, detail collapses. Defaults: 24px wide digital, 10mm wide print for the full lockup; the mark-only may go smaller (favicon).
- File + favicon matrix — ship the formats below. SVG is the digital primary (scales, tiny); PNG carries transparency; JPEG is print-safe; 72 DPI digital / 300 DPI print.
| Asset | Format | Notes |
|---|---|---|
| Logo (digital primary) | SVG | Vector, scales infinitely, smallest |
| Logo (raster, transparency) | PNG | @1x/@2x, transparent bg |
| Logo (print) | JPEG/PDF | 300 DPI, CMYK |

What ships with it
5 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.
- 11d ago First seen · 136 lines · 83 tokens per session scan A c95955ef1d54
brand-identity is a skill published in the GitHub repository ericrisco/rsc-harness (78 stars, last pushed yesterday), licensed MIT. It adds 83 tokens to every session and 2,759 once invoked, about $0.0004 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.
