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 | $0.00086 | $0.01782 |
| Opus 5.5 | $0.00034 | $0.00713 |
| Sonnet 5.5 | $0.00017 | $0.00356 |
| Haiku 4.5 | $0.00009 | $0.00178 |
Grade A, and why
apex-python-diagrams 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 23d 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.

Python Diagrams & Charts
Skill for generating diagrams and charts using Python libraries: matplotlib
for WAF/cost/compliance visualizations, diagrams for architecture diagrams,
and graphviz for ERDs, swimlanes, timelines, and wireframes.
Prerequisites
pip install diagrams matplotlib pillow && apt-get install -y graphviz
Routing Guide
Workflow charts and library-rendered diagrams emit both PNG and SVG siblings via the shared
scripts/diagram_io.py helper — PNG for raster
preview, SVG for scalable / accessible / diff-friendly review. Standalone SVG
wireframes are the exception below; they do not use this helper.
| Diagram type | Library | Output |
|---|---|---|
| WAF bar charts | matplotlib | .py + .png + .svg |
| Cost donut / projection charts | matplotlib | .py + .png + .svg |
| Compliance gap charts | matplotlib | .py + .png + .svg |
| Architecture diagrams | diagrams | .py + .png + .svg |
| Swimlane / business process | graphviz | .py + .png + .svg |
| Entity-relationship diagrams | graphviz | .py + .png + .svg |
| Timeline / Gantt charts | matplotlib | .py + .png + .svg |
| UI wireframes | SVG / graphviz | .py + .svg; PNG optional for SVG generator |
Required Outputs (Workflow Integration)

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.

apex-python-diagrams is a skill published in the GitHub repository jonathan-vella/apex-accelerator (50 stars, last pushed 2d ago), licensed MIT. It adds 86 tokens to every session and 1,782 once invoked, about $0.0003 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 2026-09-23.
