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.

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 | $0.00098 | $0.01876 |
| Opus 5.5 | $0.00039 | $0.00750 |
| Sonnet 5.5 | $0.00020 | $0.00375 |
| Haiku 4.5 | $0.00010 | $0.00188 |
Grade A, and why
mermaid-diagramming 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 1mo 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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mermaid Diagramming
Produce Mermaid diagrams that use the project's blue-gray theme. Every diagram must include the theme init directive as its first line.
Theme Directive
Paste this as the first line inside every ```mermaid block, before the diagram type declaration:
%%{init: {'theme': 'base', 'themeVariables': {'primaryColor': '#dbeafe', 'primaryTextColor': '#1e3a5f', 'primaryBorderColor': '#3b82f6', 'lineColor': '#64748b', 'secondaryColor': '#f1f5f9', 'tertiaryColor': '#e0f2fe', 'background': '#ffffff', 'mainBkg': '#dbeafe', 'nodeBorder': '#2563eb', 'clusterBkg': '#eff6ff', 'clusterBorder': '#bfdbfe', 'titleColor': '#1e3a5f', 'edgeLabelBackground': '#f8fafc'}}}%%

Rules
- Always include the theme directive. No exceptions — every
```mermaidblock in this repo starts with the%%{init}%%line. - One diagram per concept. If a section needs multiple views, use separate fenced blocks with a heading for each.
- Keep labels short. Node labels ≤ 6 words. Use subgraphs for grouping, not long labels.
- Decision nodes use
{...}rhombus shape. Action nodes use[...]rectangles. Terminal/IO nodes use[/..../]parallelograms. - Left-to-right for pipelines, top-to-bottom for hierarchies. Default to
LRfor data flow;TDfor org charts, call trees, and phase sequences.
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.

mermaid-diagramming is a skill published in the GitHub repository bdfinst/agentic-dev-team (295 stars, last pushed 4d ago), licensed MIT. It adds 98 tokens to every session and 1,876 once invoked, about $0.0004 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 2026-09-03.
