Softaworks Agent Toolkit is a collection of packaged instructions, scripts, agents, and commands that give AI coding assistants reusable procedures for development, documentation, planning, and professional work. Developers install its components individually in compatible coding-agent environments; catalogue entries represent parts of this toolkit.
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 | $0.00082 | $0.02594 |
| Opus 5.5 | $0.00033 | $0.01038 |
| Sonnet 5.5 | $0.00016 | $0.00519 |
| Haiku 4.5 | $0.00008 | $0.00259 |
Grade A, and why
c4-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 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.

The opening of the file, as written. The whole thing — 296 lines — stays where its author put it; the contents beside it link to each section on GitHub.
C4 Architecture Documentation
Generate software architecture documentation using C4 model diagrams in Mermaid syntax.
Workflow
- Understand scope - Determine which C4 level(s) are needed based on audience
- Analyze codebase - Explore the system to identify components, containers, and relationships
- Generate diagrams - Create Mermaid C4 diagrams at appropriate abstraction levels
- Document - Write diagrams to markdown files with explanatory context
C4 Diagram Levels
Select the appropriate level based on the documentation need:
| Level | Diagram Type | Audience | Shows | When to Create |
|---|---|---|---|---|
| 1 | C4Context | Everyone | System + external actors | Always (required) |
| 2 | C4Container | Technical | Apps, databases, services | Always (required) |
| 3 | C4Component | Developers | Internal components | Only if adds value |
| 4 | C4Deployment | DevOps | Infrastructure nodes | For production systems |
| - | C4Dynamic | Technical | Request flows (numbered) | For complex workflows |
Key Insight: "Context + Container diagrams are sufficient for most software development teams." Only create Component/Code diagrams when they genuinely add value.
Quick Start Examples
System Context (Level 1)
C4Context
title System Context - Workout Tracker
Person(user, "User", "Tracks workouts and exercises")
System(app, "Workout Tracker", "Vue PWA for tracking strength and CrossFit workouts")
System_Ext(browser, "Web Browser", "Stores data in IndexedDB")
Rel(user, app, "Uses")
Rel(app, browser, "Persists data to", "IndexedDB")
Container Diagram (Level 2)
C4Container
title Container Diagram - Workout Tracker
Person(user, "User", "Tracks workouts")
Container_Boundary(app, "Workout Tracker PWA") {
Container(spa, "SPA", "Vue 3, TypeScript", "Single-page application")
Container(pinia, "State Management", "Pinia", "Manages application state")
ContainerDb(indexeddb, "IndexedDB", "Dexie", "Local workout storage")
}
Rel(user, spa, "Uses")
Rel(spa, pinia, "Reads/writes state")
Rel(pinia, indexeddb, "Persists", "Dexie ORM")
What ships with it
4 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.

c4-architecture is a skill published in the GitHub repository softaworks/agent-toolkit (2,595 stars, last pushed 7mo ago), licensed MIT. It adds 82 tokens to every session and 2,594 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 2026-08-30.
