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 | $0.00032 | $0.00801 |
| Opus 5.5 | $0.00013 | $0.00320 |
| Sonnet 5.5 | $0.00006 | $0.00160 |
| Haiku 4.5 | $0.00003 | $0.00080 |
Grade A, and why
writing-fragments 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 23d 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 writing-fragments — 2 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.
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.
This is pure explore: widen the space of what could be written without committing to structure. Committing is exploit, a separate skill's job. Run a grilling session that produces fragments, interviewing the user relentlessly about whatever they want to write about. Imposing phases, outlines, or article structure is out of scope here.
As fragments emerge from either side of the conversation, append them to a single markdown file.
If the user did not pass a path, ask once where to save the document, then remember it for the rest of the session.
Capture fragments from the very first thing the user says, including the initial prompt.
On first write, put a single H1 at the top with a working title (it can change later) and nothing else: no metadata, no TOC, no date.
What is a fragment
A fragment is any piece of text that might survive into the final article. It must be readable by the author (the author can tell what it means), but it does not need to define its terms or be comprehensible to a cold reader. The bar is "is this a piece of good writing?", not "is this a self-contained argument?"
Fragments are deliberately heterogeneous. Examples of what could be a fragment:
- A sharp sentence you'd want to deploy somewhere but don't yet know where.
- A claim with a one-line justification.
- A vignette: a thing that happened, a code snippet, a scenario, an analogy.
- A half-thought: "something about how X feels like Y, work this out later."
- A quote, a piece of dialogue, an overheard line.
- A list of related observations that hang together by feel.
- A complaint, a confession, a punchline.
- A leading word: a compact metaphor or coinage the whole piece can hang on (one term that names the idea, the way tracer bullets or fog of war names a whole pattern).
Of these, the leading word is the most valuable fragment to land. It is load-bearing: name the right one in explore and it shapes the structure, the transitions, and the title later, paying dividends through the entire exploit phase. When the conversation circles a recurring idea, push to coin a word for it.
The novelist's diary is the model: years of unstructured noticings that later get mined for raw material. Fragments are noticings.
What ships with it
1 file 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.

writing-fragments is a skill published in the GitHub repository FradSer/dotclaude (594 stars, last pushed 8d ago), licensed MIT. It adds 32 tokens to every session and 801 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 91% identical to writing-fragments, differing in 2 lines, and is treated as a copy.
