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 | $0.00158 | $0.04556 |
| Opus 5 | $0.00079 | $0.02278 |
| Sonnet 5 | $0.00032 | $0.00911 |
| Haiku 4.5 | $0.00016 | $0.00456 |
Grade A, and why
brand-library-architect 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 4d 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.

Brand Library Architect
Overview
This skill captures a phased workflow for building a complete brand library for a product. It produces a coherent set of artifacts: a render pipeline for visual assets (HTML sheets → Playwright → WebP), a documentation set rooted in locked vocabulary and voice rules, repo conventions for open-source projects, and a press kit. The phases reference each other (e.g., the press kit pulls bios from BIOS.md, the README banner cites the visual pipeline output) so cross-references work even when phases are run independently.
Every template uses {{TOKEN}} placeholders for product-specific content. Prompt the user for the relevant tokens at the start of each phase rather than guessing, so the resulting library is voice-true to the product and not generically branded.
When to use this skill
Apply when the user asks for any of:
- "Build a brand library / brand kit / brand assets for product X"
- "Set up the brand library workflow for this repo"
- "Create a positioning manifesto + visual identity"
- "Author a press kit / FAQ / glossary / tone guide / pricing doc / founder bio"
- "Add CONTRIBUTING / SECURITY / CODE_OF_CONDUCT to this repo with brand voice"
- "I have visual assets — help me write the brand documentation that anchors them" (or vice versa)
- "Audit the brand assets in this repo" / "What brand assets do we have?" / "Discover existing brand surface" → run Phase 0 only as a standalone audit
Apply selectively when only one or two phases are needed. The phases are independent enough to mix and match.
Do not apply this skill when the user wants:
- Product feature documentation (use
documentation-production) - Generic copywriting unrelated to brand library structure (use
copywriter) - Visual UI components or design systems (use
ui-design-aestheticsorfrontend-design) - Internal-only docs (this skill is public-facing brand surface)
Phases
The workflow is seven phases (0-6). Run sequentially for a new product, or jump to a specific phase for incremental work. Phases 0 and 1 are required before any other phase.

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.

brand-library-architect is a skill published in the GitHub repository NickCrew/Claude-Cortex (38 stars, last pushed 2mo ago), licensed MIT. It adds 158 tokens to every session and 4,556 once invoked, about $0.0008 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 2026-09-03.
