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 | $0.00078 | $0.00644 |
| Opus 5 | $0.00039 | $0.00322 |
| Sonnet 5 | $0.00016 | $0.00129 |
| Haiku 4.5 | $0.00008 | $0.00064 |
Grade A, and why
writing-beats 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 8d 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 — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
The user has passed (or will pass) a markdown file of raw material.
If the user did not say where to save the article, ask once and remember the path.
Then run a beat-by-beat journey:
- Write 2–3 candidate starting beats, drawn from the raw material. Each is a different entry point into the article. Show the user the beats before writing it to the article file. The user picks one. Preview what beats that might lead to once written - as if the user is seeing a little way down the path.
- Once the user picks a starting beat, write only that beat to the article file. A beat may be one sentence or several paragraphs — whatever that beat naturally is. Stop there.
- Re-read the article file from disk. Then offer 2–3 candidate next beats — different directions the journey could pivot to from where the article now stands.
- Loop steps 2–4 until the article reaches a natural end.
What is a beat
A beat is one move in the journey. It does one thing — sets a scene, lands a point, asks a question, drops an aside, twists the angle. Then it stops, leaving the reader at a place where the next beat can pivot.
A beat is sized by what it needs:
- A single sentence if that's all the move is ("And then nothing happened for three weeks.").
- A short paragraph if the move needs setup.
- Multiple paragraphs if the beat is a self-contained vignette, argument, or example.
If a "beat" needs five paragraphs and three subheadings, it's not a beat — it's two beats glued together. Split it.
Writing one beat
Once a beat is picked, write that beat only to the article file. Do not write the next beat.
Pull material from the raw pile to populate the beat. You can paraphrase, split, recombine, or quote. The pile is a quarry.
Ending the journey
The article ends when the journey is complete — not when the pile is empty. Most piles will have leftover fragments that don't make it in. That is fine; that is the point of having more raw material than you need.
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.

writing-beats is a skill published in the GitHub repository stevesolun/ctx (583 stars, last pushed 7d ago), licensed MIT. It adds 78 tokens to every session and 644 once invoked, about $0.0004 per session on Opus 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.
