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 | $0.00057 | $0.00610 |
| Opus 5 | $0.00028 | $0.00305 |
| Sonnet 5 | $0.00011 | $0.00122 |
| Haiku 4.5 | $0.00006 | $0.00061 |
Grade A, and why
article-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 4d 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
95% identical to article-writing — 1 line 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.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Article Writing
Write long-form content that sounds like an actual person with a point of view, not an LLM smoothing itself into paste.
When to Activate
- drafting blog posts, essays, launch posts, guides, tutorials, or newsletter issues
- turning notes, transcripts, or research into polished articles
- matching an existing founder, operator, or brand voice from examples
- tightening structure, pacing, and evidence in already-written long-form copy
Core Rules
- Lead with the concrete thing: artifact, example, output, anecdote, number, screenshot, or code.
- Explain after the example, not before.
- Keep sentences tight unless the source voice is intentionally expansive.
- Use proof instead of adjectives.
- Never invent facts, credibility, or customer evidence.
Voice Handling
If the user wants a specific voice, run brand-voice first and reuse its VOICE PROFILE.
Do not duplicate a second style-analysis pass here unless the user explicitly asks for one.
If no voice references are given, default to a sharp operator voice: concrete, unsentimental, useful.
Banned Patterns
Delete and rewrite any of these:
- "In today's rapidly evolving landscape"
- "game-changer", "cutting-edge", "revolutionary"
- "here's why this matters" as a standalone bridge
- fake vulnerability arcs
- a closing question added only to juice engagement
- biography padding that does not move the argument
- generic AI throat-clearing that delays the point
Writing Process
- Clarify the audience and purpose.
- Build a hard outline with one job per section.
- Start sections with proof, artifact, conflict, or example.
- Expand only where the next sentence earns space.
- Cut anything that sounds templated, overexplained, or self-congratulatory.
Structure Guidance
Technical Guides
- open with what the reader gets
- use code, commands, screenshots, or concrete output in major sections
- end with actionable takeaways, not a soft recap
Essays / Opinion
- start with tension, contradiction, or a specific observation
- keep one argument thread per section
- make opinions answer to evidence
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.
- 4d ago First seen · 80 lines · 57 tokens per session scan A 491f079c7e69
article-writing is a skill published in the GitHub repository ronmkr/PromptBook (2 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 57 tokens to every session and 610 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to article-writing, differing in 1 line, and is treated as a copy.

Skill "pi-autoresearch-loop" from twaldin/flt, covering pi-autoresearch — autonomous experiment loop, installation, quick start, core concepts and two-file persistence model.
grill
Rigorous requirements gathering through Socratic questioning. Use when the user says "/grill", "grill me", "ask me questions until we understand", or wants to be interrogated about implementation details before writing code. Forces deep thinking about edge cases, behavior, and design decisions before any code is…
grill-with-docs
Grilling session that challenges your plan against the existing domain model, sharpens terminology, and updates documentation (CONTEXT.md, ADRs) inline as decisions crystallise. Use when user wants to stress-test a plan against their project's language and documented decisions.
find-skills
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
improve-codebase-architecture
Find deepening opportunities in a codebase, informed by the domain language in CONTEXT.md and the decisions in docs/adr/. Use when the user wants to improve architecture, find refactoring opportunities, consolidate tightly-coupled modules, or make a codebase more testable and AI-navigable.
