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 | $0.00062 | $0.01307 |
| Opus 5.5 | $0.00025 | $0.00523 |
| Sonnet 5.5 | $0.00012 | $0.00261 |
| Haiku 4.5 | $0.00006 | $0.00131 |
Grade A, and why
pragmatic-writing 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 — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Pragmatic Writing Skill
Writing style modeled on the masters of technical communication: Andy Hunt, Dave Thomas (The Pragmatic Programmer), and Joel Spolsky (Joel on Software). This skill transforms technical content into engaging, memorable prose.
When to Use This Skill
This skill applies when:
- Creating technical blog posts, essays, or articles
- Writing documentation that needs personality
- Explaining complex concepts to developers
- Crafting tutorials or how-to guides
- Writing "lessons learned" or postmortem content
- Any technical writing that should be read, not just referenced
Core Philosophy
"The difference between 'almost right' and 'right' is the difference between the lightning bug and the lightning." — Mark Twain (quoted by Pragmatic Programmers)
Technical writing doesn't have to be dry. The best technical writers make complex ideas feel obvious, use concrete examples before abstract theory, and treat the reader as a smart colleague.
The 10 Core Techniques
Reference the complete technique guide at techniques.md.
1. Concrete Before Abstract
Always start with a concrete example, then extract the principle.
❌ "Dependency injection is a design pattern where dependencies are passed
to objects rather than created by them."
✅ "Imagine your class needs a database connection. You could create it
yourself:
def initialize
@db = Database.new("localhost:5432")
end
But now your class is stuck with that exact database. What if you
want to test with a fake one? What if production uses a different host?
Instead, accept it as a parameter:
def initialize(db)
@db = db
end
That's dependency injection. Simple."
2. Physical Analogies
Map abstract concepts to physical experiences readers already understand.
See examples.md for analogy patterns:
- Software abstractions → Physical tools
- Code patterns → Architectural patterns
- System design → Everyday systems (postal service, restaurants)
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.

pragmatic-writing is a skill published in the GitHub repository robertguss/claude-code-toolkit (130 stars, last pushed 1mo ago), licensed MIT. It adds 62 tokens to every session and 1,307 once invoked, about $0.0002 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.
