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 | $0.00041 | $0.00364 |
| Opus 5.5 | $0.00016 | $0.00146 |
| Sonnet 5.5 | $0.00008 | $0.00073 |
| Haiku 4.5 | $0.00004 | $0.00036 |
Grade A, and why
library-architecture 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 2mo 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
Library Architecture
A reference library is only as good as your ability to find the right reference at the right time.
How to use
/library-architectureApply library design constraints to this conversation.
Constraints
System Requirements
- MUST use one tool, not three. Pick one and commit.
- MUST support tags and search. If you can't find a reference in 60 seconds, the system is failing.
- MUST save screenshots, not bookmarks. URLs die. Products redesign. Screenshots are permanent.
- SHOULD include a cropped detail of the specific thing that caught your eye alongside the full screenshot
Content Rules
- MUST collect decisions, not aesthetics. A checkout flow screenshot is more useful than a beautiful hero.
- MUST collect from outside your domain. At most 40% should be from your own industry.
- MUST collect across time. Include work from the 1950s alongside work from this month.
- SHOULD collect problems too. A well-crafted design that fails at some level teaches more than obvious success.
Maintenance
- Monthly: add minimum 10 new references, remove 5 that aren't earning their place
- Quarterly: review tags. Are you using all of them? Are there missing categories?
- MUST prune ruthlessly. 200 strong references beats 2,000 unsorted screenshots.
Anti-Patterns
- Saving everything without curation (hoarding is not collecting)
- Only saving work from your own domain
- Never revisiting or pruning the library
- Using multiple tools with no single source of truth
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.

library-architecture is a skill published in the GitHub repository Dragoon0x/taste-skills (7 stars, last pushed 8mo ago), licensed MIT. It adds 41 tokens to every session and 364 once invoked, about $0.0002 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 2026-08-31.
