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 | $0.00118 | $0.02158 |
| Opus 5.5 | $0.00047 | $0.00863 |
| Sonnet 5.5 | $0.00024 | $0.00432 |
| Haiku 4.5 | $0.00012 | $0.00216 |
Grade A, and why
diagram-generator 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.
This is a copy
91% identical to diagram-generator — 60 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Diagram Generator
ACTION REQUIRED (execute immediately after reading)
NOW: Confirm whether the current task falls within this skill's scopeNOW: Read../tool-index.mdto verify tool availability and actual pathsNEXT: If a tool is missing, invoke bootstrap — do not guess pathsACT: Enter the first step of the "Workflow" and execute — do not stop at the confirmation stage
Purpose
Create clear, editable diagrams from messy or structured inputs. Prefer text-based diagram source first so the result can be reviewed, versioned, and refined. Render to files only when the user asks for an image/PDF or when a downloadable artifact would materially help.
Default workflow
- Identify the user's intent, audience, and source material.
- Choose the diagram family and language using the decision table below.
- Normalize entities, relationships, labels, states, branches, and time/order information before writing diagram code.
- Generate concise, readable diagram source.
- Validate the syntax mentally and, when creating files, run
scripts/render_diagram.py. - Return the diagram source plus a short note about assumptions. When files are generated, include links to the output files.
Do not over-ask for clarification. If the request is underspecified, make reasonable assumptions and label them briefly.
Diagram language decision table
Use Mermaid unless another language is clearly better.
| User wants | Prefer | Why |
|---|---|---|
| process flow, decision tree, simple swimlane | Mermaid flowchart | readable and easy to paste into Markdown |
| sequence of system/user interactions | Mermaid sequenceDiagram or PlantUML sequence | Mermaid for docs; PlantUML for UML formality |
| lifecycle, state machine, transitions | Mermaid stateDiagram-v2 or PlantUML state | compact transition syntax |
| database schema, entities, relationships | Mermaid erDiagram | portable ER notation |
| class/interface/object model | Mermaid classDiagram or PlantUML class | Mermaid for docs; PlantUML for detailed UML |
| project schedule | Mermaid gantt | concise timeline syntax |
| hierarchy, ideas, notes | Mermaid mindmap | good default for idea maps |
| customer/product journey | Mermaid journey | built-in journey notation |
| git history | Mermaid gitGraph | built-in git notation |
| dependency graph, package graph, large network | Graphviz DOT | better layout engines for dense graphs |
| architecture with layers, clusters, boundaries | Mermaid flowchart with subgraphs, Graphviz clusters, or PlantUML C4-style | choose based on requested fidelity |
| weighted flow/sankey-like relationship | Mermaid sankey-beta when supported, otherwise SVG or Graphviz | Mermaid support may vary by renderer |
| custom visual where source languages fit poorly | SVG | precise control over layout and styling |
What ships with it
5 files 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.

diagram-generator is a skill published in the GitHub repository xAmirHamza77/ReverseOps-Skill (5 stars, last pushed 3mo ago), licensed MIT. It adds 118 tokens to every session and 2,158 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 91% identical to diagram-generator, differing in 60 lines, and is treated as a copy.
