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 | $0.00037 | $0.04311 |
| Opus 5 | $0.00018 | $0.02155 |
| Sonnet 5 | $0.00007 | $0.00862 |
| Haiku 4.5 | $0.00004 | $0.00431 |
Grade A, and why
Asset Manager scanned grade A with 1 finding 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 9d 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.

Expected in a hook, worth knowing in a rule or an instructions file.

Asset Manager
Keep design assets organized, optimized, and accessible.
Core Principle
Organized assets = faster development.
Assets should be:
- Easy to find
- Properly named
- Optimized for production
- Version controlled
- Consistently formatted

What ships with it
1 file 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.

Asset Manager is a skill published in the GitHub repository daffy0208/ai-dev-standards (36 stars, last pushed 8mo ago), licensed MIT. It adds 37 tokens to every session and 4,311 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Handles prompt construction, API calls, base64 decoding, and file saving. Supports reference images (logos, mascots) for brand-consistent generation.
image-fetcher
Acquires visual assets from multiple sources: web image search, live website screenshots via Playwright, and user-provided files. Organizes assets in the squad's reference folder.
canva
Create, search, autofill, and export designs from Canva. Enables agents to generate visual content, fill templates with brand assets, and export in various formats.
pro-image-optimizer
